ctDNA analysis from the EVP vs chemotherapy muscle invasive bladder cancer trial (B15/EV304) shows ctDNA is strongly prognostic at all time points for both arms. EVP has higher clearance rates across time points, underlining its ⬆️ activity. Results for the control arm are strikingly similar to the ctDNA results in the chemo control arm in the NIAGARA trial. This consistency underlines the utility of ctDNA from a prognostic perspective.#ESMO26 @OncoAlert

Conclusions
• The use of perioperative EV plus pembrolizumab was not associated with a clinically meaningful detriment in general HRQoL or cystectomy-specific HRQoL
• No clinically meaningful between-group differences were observed in the prespecified HRQoL domains assessed
• The largest deterioration in most HRQoL domains was observed after surgery, followed by partial recovery in both treatment groups
• Sexual function showed clinically meaningful and persistent worsening in both treatment groups, consistent with the known impact of radical cystectomy
• Together with the efficacy and safety results observed in the primary analysis, these PRO findings further support the overall benefit-risk profile of perioperative EV plus pembrolizumab in participants with cisplatin-eligible MIBC1

Nonevaluable included samples that were not received or collected, had insufficient cell-free DNA for testing, or failed the assay
Reasons for reduced sample availability at the adjuvant time point
• The reduced sample availability at the adjuvant timepoint is likely multifactorial, reflecting:
– Expected patient attrition
– An elevated rate of test failures at adjuvant W30-34 associated with insufficient cell-free DNA and lower plasma volumes
– Timelines for procedures in the two arms were different
• Although these effects were observed across both arms, the greater frequency of assay failures and/or missed collections in the EV + pembro arm may have contributed to its higher attrition rate
ᵃPercentages are based on the intention-to-treat population (EV + pembro, n = 405; cis + gem, n = 403). ᵇBoth treatment arms combined.

Conclusions
• In this exploratory ctDNA analysis from KEYNOTE-B15, a ctDNA-positive status was associated with poor prognosis in both treatment arms
– ctDNA-negative status was associated with improved EFS (baseline and postsurgery) and pCR (presurgery) compared with ctDNA-positive status in both treatment arms
• Perioperative EV + pembro showed favorable EFS outcomes versus neoadjuvant cis + gem regardless of ctDNA status at baseline or postsurgery
• Participants with ctDNA clearance at presurgery had more favorable EFS outcomes compared with those without ctDNA clearance
• ctDNA clearance at presurgery was higher with EV + pembro versus cis + gem
– Participants in the EV + pembro arm with ctDNA clearance had improved EFS versus those in the cis + gem arm with ctDNA clearance
• These findings show that ctDNA is strongly prognostic, regardless of therapy in this study
• ctDNA clearance was higher with EV + pembro than with cis + gem

KEYNOTE-B15 / EV-304
1) Biomarker data: Presurgery ctDNA+ Predicts Low pCR, Any Regimen — pCR · 2) Biomarker data: ctDNA Clearers Fare Better With Perioperative EV + Pembro — EFS · 3) Biomarker data: Perioperative EV + pembro with serial ctDNA assessment
KEYNOTE-B15 ctDNA analysis presented by Jonathan Chatzkel at #ESMO26, with Min Teo as discussant 🧬 In cisplatin-eligible MIBC, ctDNA+ before surgery meant almost no pCR with either regimen (3.7% with EV + pembro, 2.2% with cis/gem). Among ctDNA− patients, pCR was 72.4% with EV + pembro vs 43.7% with cis/gem. In the EV + pembro arm, patients who cleared ctDNA had 24-month EFS of 81% vs 33% with persistent ctDNA+. The postsurgery results replicate NIAGARA. Serial ctDNA could open the door to bladder-sparing and surveillance questions. #MRD #ctDNA #BladderCancer

ctDNA Analysis of the Phase III KEYNOTE-B15 Trial: Neoadjuvant and Adjuvant Enfortumab Vedotin + Pembrolizumab in Cisplatin-Eligible Muscle-Invasive Bladder Cancer
🎤 Presented by Jonathan Chatzkel 🇺🇸 | Moffitt Cancer Center
@OncoAlert @urologysummit
🧬 Can molecular response help redefine perioperative treatment in MIBC?
🔬 STUDY DESIGN
Phase III KEYNOTE-B15/EV-304 | N=808
🟢 Perioperative EV + pembrolizumab (n=405)
🔴 Neoadjuvant gemcitabine/cisplatin followed by observation (n=403)
All patients underwent planned radical cystectomy + PLND.
Exploratory ctDNA analysis using the tumor-informed Signatera assay at baseline, presurgery, postsurgery and during adjuvant treatment.
📊 KEY RESULTS
🧬 1️⃣ Baseline ctDNA: a powerful prognostic marker
ctDNA positivity was associated with worse EFS.
EV + pembrolizumab vs chemotherapy:
✅ Baseline ctDNA-positive:
HR 0.54 (95% CI 0.37–0.80)
✅ Baseline ctDNA-negative:
HR 0.68 (95% CI 0.37–1.26)
📌 EFS estimates favored EV + pembrolizumab in both subgroups, although the CI crossed 1 in ctDNA-negative patients.
🧬 2️⃣ ctDNA CLEARANCE BEFORE SURGERY
✅ EV + pembrolizumab: 82.1%
🔴 Gemcitabine/cisplatin: 66.7%
📈 Absolute difference: +15.4 percentage points.
Molecular clearance was associated with more favorable EFS and pathological response.
🔬 3️⃣ pCR BY PRESURGICAL ctDNA STATUS
Among patients who were ctDNA-negative before surgery:
✅ EV + pembrolizumab: 72.4%
🔴 Gemcitabine/cisplatin: 43.7%
Among those remaining ctDNA-positive:
• EV + pembrolizumab: 3.7%
• Chemotherapy: 2.2%
📌 Persistent ctDNA positivity identified patients with a very low probability of pCR.
🧬 4️⃣ POSTSURGICAL ctDNA AND EFS
EV + pembrolizumab vs chemotherapy:
✅ ctDNA-negative:
HR 0.48 (95% CI 0.29–0.81)
🔹 ctDNA-positive:
HR 0.63 (95% CI 0.30–1.35)
Postoperative ctDNA positivity was associated with particularly poor EFS.
⚠️ Interpretation requires caution: the postsurgical ctDNA-positive subgroup was small, and sample availability decreased over time.
🔬 CONCLUSIONS
✅ ctDNA positivity identifies patients with poorer prognosis.
✅ ctDNA clearance was higher with EV + pembrolizumab than with cisplatin-based chemotherapy.
✅ Molecular clearance correlated with improved pathological response and EFS.
✅ EFS estimates favored EV + pembrolizumab across ctDNA-defined groups.
⭐ MY POINT OF VIEW | CLINICAL PEARL
We are moving beyond pathological response toward molecular assessment of treatment effectiveness.
🧬 ctDNA could become an essential tool for perioperative risk stratification in MIBC.
But an important distinction remains:
Prognostic ≠ Predictive.
These findings do not yet establish ctDNA as a biomarker for selecting EV + pembrolizumab, omitting cystectomy or safely de-escalating adjuvant therapy.
💡 The next breakthrough may not be another treatment combination, but learning how to personalize treatment intensity according to molecular response.
📌 Prospective ctDNA-guided trials will be essential to translate molecular clearance into clinical decisions.

🚨 Important new ctDNA data from KEYNOTE-B15 at ESMO 2026!
In cisplatin-eligible MIBC, EV+pembrolizumab achieved:
🔹 82.1% ctDNA clearance during neoadjuvant treatment vs 66.7% with gemcitabine/cisplatin.
🔹 87.0% ctDNA negativity before surgery vs 80.3% with chemotherapy.
🔹 95.2% ctDNA negativity after cystectomy vs 86.5% with chemotherapy.
Strikingly, only 4.8% remained ctDNA-positive after neoadjuvant EV+pembrolizumab and surgery!
We know from IMvigor011 that postoperative ctDNA can identify patients at high risk of recurrence and help guide adjuvant treatment strategies.
But what about patients achieving both pCR and sustained ctDNA negativity?
Do they really need another 5–6 cycles of adjuvant EV, with the potential for cumulative tox/ neuropathy?
Could pCR + ctDNA clearance, followed by longitudinal ctDNA monitoring, define a population suitable for treatment de-escalation?
VOLGA will add another important piece to this puzzle, using only 3 neoadjuvant EV cycles without adjuvant EV.
Of course, neither KEYNOTE-B15 nor VOLGA can establish the necessity of adjuvant EV through cross-trial comparisons.
We urgently need prospective, biomarker-guided de-escalation trials—not simply more treatment for everyone.

KEYNOTE-B15 / EV-304
Biomarker data: KEYNOTE-B15/EV-304: KM EFS per BICR by ctDNA status at postsurgery
KEYNOTE-B15 ctDNA analysis, cis-eligible MIBC: EV plus pembro cleared ctDNA more often than cis-gem.
📈 Presurgery ctDNA negative: pCR 72.4% vs 43.7%
📊 24-month EFS if cleared 81.1% vs 63.2%, if ctdna persistent 33.3% vs 35.3%
🔍 Presurgery ctDNA positive: pCR only in 2 of 72 across both arms
ctDNA is prognostic in both arms. Persistent positivity does poorly on either regimen, and know seeing trial designs to address.

ESMO 2026 - presidential LBA | VOLGA Phase III –
Perioperative Durvalumab + Enfortumab Vedotin (EV) in cisplatin-ineligible/refusing patients:
📊 EV + Durva vs Control
• 2-year EFS: 64% vs 45% (HR 0.51; p<0.0001)
• 2-year OS: 78% vs 69% (HR 0.58; p=0.0027)
• pCR: 45% vs 10%
Adding tremelimumab improved EFS (HR 0.61) but no significant OS benefit yet, with higher grade 3/4 toxicity (42% vs 30%).
🔥can this stop the need of post op EV ? Probably yes . New SOC 🙂👍

The standard of care continues to evolve for patients (pts) with muscle-invasive bladder cancer (MIBC). We evaluated if neoadjuvant durvalumab (D) ± tremelimumab (T) plus enfortumab vedotin (EV) followed by radical cystectomy (RC) and adjuvant D±T would be an effective option.
[Slide 2]
Results
Overall, 233, 233, and 229 pts were randomised to the D+EV, D+T+EV, and control arms, respectively. RC was completed in 85% (D+EV), 79% (D+T+EV), and 78% (control) of pts; and 55% (D+EV) and 42% (D+T+EV) completed adjuvant tx. Median EFS follow-up was 22.9 mo. D+EV showed significant improvements in EFS (HR 0.51 [95% CI, 0.38-0.67], P<0.0001; 24-mo rate 64% vs 45%) and OS (HR 0.58 [95% CI, 0.40-0.83], P=0.0027; 24-mo rate 78% vs 69%) vs control. D+T+EV also showed a significant improvement in EFS vs control (HR 0.61 [95% CI, 0.47-0.80], P=0.0004; 24-mo rate 60% vs 45%) but did not meet significance for OS; follow-up is ongoing. Pathological complete response per local review was observed in 45% (95% CI, 38.6-51.7) of pts in the D+EV arm and 10% (95% CI, 6.1-14.2) in the control arm. In the D+EV and D+T+EV arms, max. Grade 3/4 tx-related adverse events occurred in 30% and 42% of pts, respectively. ctDNA results will also be presented.
Conclusions
Dual primary endpoints of EFS were met. Perioperative D plus 3 cycles of neoadjuvant EV also demonstrated a significant improvement in OS vs control. Safety profiles were consistent with those of the individual agents.
[Slide 3]
Methods
VOLGA (NCT04960709), a phase 3, randomised, open-label trial, enrolled pts with MIBC (cT2-T4aN0/1M0 or cT1N1M0) ineligible for or who refused treatment (tx) with cisplatin and were planned for RC. Pts were randomised 1:1:1 to D+EV, D+T+EV, or control. D+EV and D+T+EV arms: perioperative D±T (neoadjuvant: 3 cycles of D, 2 cycles of T; adjuvant: 9 cycles of D, 1 cycle of T) and 3 cycles of neoadjuvant EV; RC was completed after neoadjuvant tx. Control arm: RC and observation or locally approved adjuvant tx. Dual primary endpoints were event-free survival (EFS): D+EV vs control and D+T+EV vs control. Overall survival (OS) was the key secondary endpoint. Safety was also assessed. Here we present results from a pre-planned interim analysis (data cutoff: 02 Mar 2026).

VOLGA explored short periods of EV (3 cycles) with duvalumab in muscle invasive bladder cancer #ESMO26 @NEJM. Results showed EVD was associated with better EFS + OS vs cystectomy alone (0.51 and 0.58 respectively). pCR 40-45% with ctDNA clearance rates of 60%. High rates of adjuvant IO therapy uptake and low rates of neuropathy suggest potential advantages of this approach which focuses the ADC in the neoadjuvant phase. It’s likely to be attractive for patients.

Biomarker data: pre-RC ctDNA dynamics and EFS by ctDNA status, durvalumab+EV arm (ESMO 2026)
ctDNA analysis is an increasingly utilised prognostic tool in muscle invasive bladder cancer. In VOLGA 78% of the muscle invasive bladder cancer patients were ctDNA positive at baseline which was prognostic. Also, the combination of perioperative durvalumab and neoadjuvant EV cleared ctDNA in 60% of patients (using the Natera Genome assay which has increased sensitivity). Clearance was associated with much better outcomes. #ESMO26

VOLGA also explored short periods of EV with duvalumab and tremelimumab in muscle invasive bladder cancer #ESMO26 @NEJM. Results showed EVDT improved EFS vs cystectomy (HR 0.61). Significant OS was not reached at this interim (HR 0.77 -ongoing analysis). EVDT = 10% higher rates of G3/4 toxicity and less EV delivery than the EV durvalumab arm. More is not always better. It appears the addition of treme partly compromised delivery of EV, which likely accounts for the more modest results compared to the doublet @OncoAlert

Kudos @tompowles1 on a fantastic #VOLGA presidential @ #ESMO26 👏
Less is More!
• Cis-inelig MIBC, 25% were cis refusers • D+EV x3 → RC → adj D x9 (NO adj EV) • EFS HR 0.51 • OS HR 0.58 • pCR 45 vs 10% • G3-4 TRAE 30%, • neuropathy only 18% • imAEs 33% (G3-4 11%) • GHS/QoL maintained post-RC
• Treme ↑tox (G3-4 42%, 5 deaths), NO OS gain.
My take: it's not just about chasing bigger numbers. Tox matters too, especially when OS is achieved. Need to discuss the pros and cons with patients.
Less PN and skin tox, and fewer G3+ immune AEs than more cycles and that's a win for patients ! 🙌

VOLGA: Conclusions
• Perioperative durvalumab plus 3 cycles of neoadjuvant enfortumab vedotin demonstrated statistically significant improvements in EFS and OS vs control in patients with MIBC ineligible for or who refused cisplatin-based chemotherapy
– EFS HR 0.51 (95% CI, 0.38–0.67), P<0.0001
– OS HR 0.58 (95% CI, 0.40–0.83), P=0.0027
– EFS and OS benefits were consistent across subgroups
• Durvalumab plus enfortumab vedotin had a tolerable and manageable safety profile that was consistent with the known safety profiles of the individual agents, with quality of life maintained after surgery
• Durvalumab and tremelimumab plus enfortumab vedotin also demonstrated a statistically significant improvement in EFS vs control
– OS analysis was not statistically significant at this interim analysis; follow-up is ongoing
VOLGA supports perioperative durvalumab plus 3 cycles of neoadjuvant enfortumab vedotin as a potential new standard of care for patients with MIBC ineligible for or who refused cisplatin-based chemotherapy

📈 EFS HR 0.51, OS HR 0.58. 24-mo OS 78% vs 69%
📝 EV stopped at surgery. Durvalumab continued for 9 adjuvant cycles, and pCR was 45% vs 10%
⚠️ Adding tremelimumab: OS HR 0.77, p=0.12, grade 3-4 AEs 70% vs 64%
Tremelimumab added toxicity without a significant OS gain at this interim, final OS pending. Congrats to the team and wonderful to see ctDNA and QoL in this presentation!

DASL-HiCaP Conclusions:
• The addition of darolutamide to 2 years of ADT and primary or Salvage RT including pelvic nodal radiation significantly improved MFS-CI for patients with DASL very-high risk prostate cancer.
• MFS-CI is a proven surrogate (early intermediate clinical endpoint) for OS in this setting.
• This benefit was consistent across all subgroups.
• PSA-PFS, time to subsequent therapy, and time to CRPC, all favoured darolutamide.
• The treatment burden was similar to placebo with limited additional burden.
• Darolutamide reduces the risk of relapse to a clinically meaningful degree, as such it defines a new paradigm for the care of patients with prostate cancer at very high risk of recurrence and being treated with curative intent radiotherapy.

Slide: rationale / unmet need (Niazi, ESMO 2026)
Compelling presentation by Tamim Niazi! DASL-HiCaP: adding darolutamide to ADT + RT improved MFS in very high-risk nonmetastatic prostate cancer (HR 0.42; 4-year MFS 95% vs 88%). Important phase III evidence for intensification! #ESMO26 @oncoalert @myESMO https://t.co/ALgNRFY3ka
[Slide 1]
DASL-HiCaP Rationale
Unmet need:
• At study inception in 2019, long course ADT + radiation was the standard of care for patients treated with primary radiation therapy for localized/locally advanced prostate cancer at very high risk of relapse.
• STAMPEDE in 2022 and ENZARAD in 2025 reported some patients do benefit from addition of abiraterone or enzalutamide (pelvic RT) to standard long course ADT plus radiation therapy.
• In 2026, there is still uncertainty as to which patients having standard of care Radiation and ADT will most likely benefit from systemic treatment intensification.

[Slide 2]
Key questions for patients with high-risk localised or relapsed prostate cancer treated with radiotherapy
• Does the addition of an ARPI* to RT + ADT** improve outcomes?
• Who benefits from the addition of RT to the pelvis?
• In which patients can we de-escalate treatment?
2 settings:
1. High-risk localised disease (treatment-naïve)
2. Post radical prostatectomy: High-risk salvage RT setting
*Androgen receptor pathway inhibitor
e.g. Abiraterone, Apalutamide, Darolutamide, Enzalutamide
**Androgen deprivation therapy

Strengths
• Academic, large, blinded, international trial with > 1000 patients
• Addresses an important question in the era of modern radiotherapy
• Inclusion of patients with high-risk relapsed disease
• PSMA PET scans and sample collection done and will support further research
Considerations
• Heterogenous patient population including treatment naïve and relapsed patients
• Early results from the interim analysis, final analysis awaited; OS data immature
• The question which patients with N0 disease benefit from addition of RT to the pelvis cannot be answered, since all patients received it
• Introducing a new definition of «very high-risk»

From clinical risk factors to biology
Today — Clinical selection
• cN1 M0 in conventional imaging
• Gleason 9/10 (and other DASL-HiCaP criteria)
• STAMPEDE: ≥2 of T3–4, GS 8–10, PSA ≥40
Next step — Retrospective validation
• Application of MMAI and Decipher to tissue from DASL-HiCaP, ENZARAD and other trials in this setting
• Meta-analysis of individual patient data across trials
• Analysis of treatment effects in patients with PSMA PET positivity
Future — Prospective selection
Biomarker-driven trials:
• PREDICT-RT (NCT04513717), using Decipher
• GUIDANCE (NCT05050084), using Decipher
• THUNDER (NCT06282588), using Decipher and PSMA PET
These trials incorporate modern biology for treatment selection and De-escalation strategies to minimise toxicity

DASL-HiCaP: darolutamide on top of 96 weeks of ADT plus RT improved MFS in very high-risk localized prostate cancer, HR 0.42, 4-yr MFS 95% vs 88%.
📈 n=1,106, interim at 67% of events, 46 mo follow-up. OS immature
📝 Thanks to @Silke_Gillessen putting this into context STAMPEDE M0 (HR 0.53) and ENZARAD (HR 0.88): not contradictory, the ARPI benefit tracks metastatic risk
🎯 N1 is the clearest indication. N0 is less clear, and Gleason seems to matter
Every patient got pelvic RT, so who needs it in N0 not yet answered.

Clinical implications
• DASL-HiCaP is statistically positive: 96 wks of ADT plus Darolutamide and prostate and pelvic RT improve MFS-CI for patients with very high-risk prostate cancer. Final analysis and OS awaited
• Added toxicity seems limited and this should be considered in the risk to benefit ratio. Also life expectancy is relevant in this context
• The clearest indication is in patients with N1 disease. This is supported by subset analysis of the trials with Abiraterone and Enzalutamide that also look positive in this subgroup
• For N0 disease, the indication is less clear. Gleason seems to be important and suggests biology is relevant: more work on biomarkers is needed
• Patients with very high-risk relapsed disease seem to have the same treatment effect, however few such patients were included in the trial

Conclusions
• This data does help to resolve the difference of the results of the other two trials, which is based around the proportion of patients at risk. They are not contradictory, the ARPI benefit seems to appear when the risk of metastases is high and disappears in lower-risk N0 patients (ENZARAD)
• The role of pelvic radiotherapy in very high-risk N0 patients has yet to be resolved
• We need to re-define "very high-risk" incorporating modern imaging and biomarkers
• In the future we should evaluate not only intensification, but biomarker driven de-escalation to avoid overtreatment in this group of patients, ideally with non-testosterone suppressing strategies

aAssessed by the Dako PD-L1 IHC 28-8 pharmDx assay. bAll patients receive GC chemotherapy on a Q3W schedule. Dose and schedule depend on the patient's calculated GFR. GFR >= 60 mL/min: gemcitabine 1000 mg/m2 D1, D8; cisplatin 70 mg/m2 D1; GFR 50 to < 60 mL/min: gemcitabine 1000 mg/m2 D1, D8; cisplatin 35 mg/m2 D1, D8. cA third arm (NIVO + linrodostat + GC/NIVO + linrodostat) was terminated. dpCR rate was defined by the proportion of randomized patients with absence of any cancer (T0 and N0) in pathology specimens after RC, based on blinded pathology review. EFS was defined as the time from randomization to any of the following events: progression of disease that precludes RC surgery, local or distant recurrence based on BICR assessments, or death due to any cause. OS was defined as the time between the date of randomization and the date of death from any cause.

Bravo @AndreaNecchi on a superb presentation of ENERGIZE trial at @myESMO #ESMO26 ! 👏
Ph3, n=653 cis-eligible MIBC: neoadj GC + nivo → adj nivo vs GC alone.
Median f/u 54.5 mo.
🔹 pCR 39.1% vs 29.6%: not dig 🔹 EFS HR 0.94: co-primaries not met 🔹 OS HR 0.88
👉Negative trial, but the ctDNA data are a key message: detectable ctDNA at baseline and after NAC strongly prognostic for worse EFS & OS.
Selecting patients by ctDNA, rather than adding IO for all, is where the field is heading!
Great to see this build on our Ph2 BLASST-1. Despite the negative result, it's very practice-informing.
Proud to be a part of this effort!

Summary
- In CA017-078, adding perioperative NIVO to neoadjuvant GC increased the pCR rate vs GC alone (39.1% vs 29.6%); however, the prespecified statistical threshold for the co-primary endpoint of pCR was not met
- The co-primary endpoint of EFS was not improved with NIVO+GC vs GC (HR, 0.94; P value, 0.6697), and OS data were immature with no clear treatment difference (HR, 0.88)
- The safety profile of NIVO+GC was consistent with that of the individual agents1,2
- Exploratory analyses suggested that pretreatment ctDNA status and ctDNA clearance during neoadjuvant treatment were prognostic (patients who were ctDNA-negative before treatment or achieved ctDNA clearance had better EFS and OS in both treatment arms)
- Although the co-primary endpoints were not met, these mature randomized phase 3 data - including exploratory ctDNA analyses - are practice-informing

🚨⭐🟠 #ESMO26 | Abstract 4736O | ENERGIZE (CA017-078)
Phase III trial of neoadjuvant chemotherapy ± nivolumab followed by adjuvant nivolumab in muscle-invasive bladder cancer (MIBC)
🎤 Presented by @AndreaNecchi 🇮🇹
@OncoAlert @urologysummit
🔬 Can perioperative nivolumab improve outcomes in patients with cisplatin-eligible MIBC?
📊 STUDY DESIGN
Phase III randomized trial | N=653
🔹 Nivolumab + gemcitabine/cisplatin → radical cystectomy → adjuvant nivolumab (n=325)
🔹 Gemcitabine/cisplatin → radical cystectomy → observation (n=328)
📊 KEY RESULTS
❌ Event-free survival (co-primary endpoint)
• Median EFS: NR vs 67.6 months
• HR 0.94 (95% CI 0.72–1.24)
• p=0.6697
➡️ No statistically significant improvement.
📈 Pathological complete response (co-primary endpoint)
• pCR: 39.1% vs 29.6%
• Absolute difference: +9.5 percentage points
❌ Did not meet the prespecified multiplicity-adjusted significance threshold.
🔬 Combined pathological response (≤ypT1N0)
• 51.7% vs 41.8%
🧬 ctDNA EXPLORATORY ANALYSIS
✅ Neoadjuvant ctDNA clearance:
• 81.3% vs 71.7%
📌 Pretreatment ctDNA positivity was associated with shorter EFS and OS.
However, no clear differential treatment benefit was observed according to baseline ctDNA status.
📊 Overall survival
• OS data remain immature.
• No established survival advantage.
⚠️ Safety was consistent with the known profiles of the individual agents.
🔬 CONCLUSION
Adding perioperative nivolumab to neoadjuvant gemcitabine/cisplatin did not significantly improve the co-primary endpoints of pCR or EFS in patients with MIBC.
⭐ MY POINT OF VIEW | CLINICAL PEARL
Improving pathological response does not necessarily translate into better long-term outcomes.
ENERGIZE reinforces an essential principle in perioperative oncology: pCR signals must be interpreted alongside EFS, OS, toxicity and statistical robustness.
🧬 ctDNA is emerging as a powerful prognostic biomarker, but its ability to guide treatment intensification or de-escalation still requires prospective validation.
💡 The future of perioperative MIBC treatment is not simply adding more immunotherapy. It is identifying who truly benefits—and who can safely avoid unnecessary treatment.

pCR by subgroups (Patients %):
PD-L1 ≥1%: 46.4 | 35.5; difference 10.9% (95% CI [illegible])
PD-L1 <1%: 33.3 | 24.3; difference 9.1% (95% CI [illegible])

Combined response (≤ ypT1N0) - Overall ITT: 51.7 | 41.8; difference 9.9% (95% CI [illegible])
Legend: NIVO+GC; GC
• Overall pCR rate was higher with NIVO+GC, but the multiplicity-adjusted analysis did not establish a significant difference
• Descriptive pCR rates were higher with NIVO+GC in both PD-L1 strata and in the cT2 and cT3/cT4a subgroups
• Overall combined response rate (≤ ypT1N0) was higher with NIVO+GC
aResults shown are from a descriptive pCR update at the EFS final analysis cutoff. The prespecified pCR final analysis had already been completed, and formal hypothesis testing was not repeated. Therefore, no P value is reported. bThe pCR hypothesis was evaluated at the multiplicity-adjusted 2-sided nominal significance level of 0.0009[illegible] at the final analysis, corresponding to a 99.9x% CI. Conventional 95% CIs were also reported descriptively.

ctDNA testing was performed using the Signatera tumor-informed molecular residual disease assay (Natera, Austin, TX, USA). ctDNA clearance status was categorized as positive at C1D1 but negative by C4D1 (cleared), or positive at both C1D1 and C4D1 (not cleared). The ctDNA-evaluable population (patients with ctDNA results for both C1D1 and C4D1) comprised 53.0% (346/653) of all randomly assigned patients. The ctDNA-evaluable population was representative of the total study population across all demographic features and baseline demographic characteristics were well balanced between the treatment arms.

Perioperative nivolumab plus neoadjuvant GC in resectable MIBC: final results and ctDNA analysis
CA017-078 (ENERGIZE; NCT03661320): randomized phase III trial of nivolumab + GC → radical cystectomy → adjuvant nivolumab (n=325) versus GC → radical cystectomy (n=328)
Key inclusion criteria
• Adults ≥18 years with previously untreated cT2-T4aN0/1M0 MIBC
• Fit for radical cystectomy and eligible for cisplatin (creatinine clearance ≥50 mL/min)
• Eastern Cooperative Oncology Group performance status 0-1
Study highlights
• Perioperative nivolumab did not significantly improve pCR or EFS; neither co-primary endpoint was met
• Grade 3-4 treatment-related AEs: 50.0% vs 49.5%
• There was one treatment-related death with nivolumab + GC
• ctDNA presence was prognostic in exploratory analyses

Conclusions
- KEYNOTE-866 is the first placebo-controlled trial to add perioperative PD-1(L)1-based immunotherapy to neoadjuvant cisplatin plus gemcitabine and RC + PLND for MIBC
- The addition of pembrolizumab to cisplatin plus gemcitabine did not confer a statistically significant EFS benefit in participants with MIBC who were eligible for cisplatin
- EFS outcomes were generally consistent across key subgroups
- The key secondary endpoints of OS and pCR rate were not formally tested for statistical significance per the statistical design
- OS was similar between the treatment groups
- pCR rate was numerically higher in the pembrolizumab group compared with the placebo group (44.4% vs 35.8%)
- Efficacy outcomes in the placebo group surpassed conventional benchmarks for neoadjuvant cisplatin plus gemcitabine and RC + PLND in MIBC1
- The safety profile of perioperative pembrolizumab added to standard-of-care neoadjuvant cisplatin plus gemcitabine and RC + PLND was manageable and consistent with prior reports with no new safety signals2,3
- While perioperative pembrolizumab plus neoadjuvant cisplatin-based chemotherapy is not supported for participants with MIBC, perioperative enfortumab vedotin plus pembrolizumab has become a standard of care in this disease setting4,5

Perioperative pembrolizumab or placebo + neoadjuvant cisplatin and gemcitabine in muscle-invasive bladder cancer: Phase III KEYNOTE-866
🎤 Presented by Jens Bedke 🇩🇪
@OncoAlert
🔬 Can adding perioperative pembrolizumab to cisplatin-based neoadjuvant chemotherapy improve outcomes in cisplatin-eligible MIBC?
📊 STUDY DESIGN
Phase III, randomized, double-blind, placebo-controlled trial.
👥 N=907 patients with cisplatin-eligible MIBC.
🔹 Pembrolizumab + gemcitabine/cisplatin → radical cystectomy → adjuvant pembrolizumab (n=453)
🔹 Placebo + gemcitabine/cisplatin → radical cystectomy → adjuvant placebo (n=454)
Median follow-up: 60.9 months.
📊 KEY RESULTS
❌ Event-free survival (PRIMARY ENDPOINT)
• Median EFS: 74.1 months vs NR
• HR 0.88 (95% CI 0.71–1.10)
• p=0.1366
➡️ No statistically significant EFS improvement.
📈 Pathological complete response (pCR)
✅ 44.4% vs 35.8%
• Estimated difference: +8.9 percentage points (95% CI 2.5–15.1).
⚠️ Higher pCR did NOT translate into a statistically significant improvement in the primary EFS endpoint.
📊 Overall survival
• Median OS: NR in both arms
• HR 1.00 (95% CI 0.79–1.27)
➡️ No observed OS advantage.
pCR and OS were not formally tested for statistical significance under the hierarchical testing strategy.
🏥 Surgery
• Underwent cystectomy: 91.6% vs 87.9%.
⚠️ SAFETY
• Grade 3–5 treatment-emergent AEs: 80.2% vs 75.1%.
• Grade 3–5 immune-mediated AEs/infusion reactions: 8.9% vs 1.8%.
🔬 CONCLUSION
KEYNOTE-866 did not meet its primary EFS endpoint. Despite increased pCR rates, perioperative pembrolizumab added to neoadjuvant cisplatin/gemcitabine did not demonstrate a significant EFS benefit.
⭐ MY POINT OF VIEW | CLINICAL PEARL
A higher pathological response rate is encouraging, but it is not enough to redefine a standard of care.
In curative-intent MIBC, durable disease control and survival must drive treatment decisions.
📌 These findings do not support routinely adding perioperative pembrolizumab to neoadjuvant gemcitabine/cisplatin in cisplatin-eligible MIBC.
💡 More treatment does not necessarily mean better outcomes. The real challenge is identifying which patients benefit from intensification—and which do not.

Kaplan-Meier survival data: EFS figure from journal pre-proof - pembrolizumab
KEYNOTE-866: No significant EFS benefit with perioperative pembro + gem/cis (HR 0.88, p=0.14) and no OS signal (HR 1.00).
Why did the control arm perform so well? More cT2 disease? No split-dose cisplatin? Important differences vs NIAGARA.

KEYNOTE-866
Kaplan-Meier survival data: primary endpoint - EFS by investigator assessment, ITT
#ESMO26 🚨 KEYNOTE-866: The final EFS analysis (N=907) of perioperative pembrolizumab + cisplatin/gemcitabine vs chemotherapy alone:
🔹 5-year EFS: 63.5% vs 61.9% (HR 0.88; p=0.137)
🔹 5-year OS: 70.8% vs 70.9% (HR 1.00)
🔹 pCR: 44.4% vs 35.8%
🔹 Grade 3–5 AEs: 80.2% vs 75.1%
Despite a numerically higher pCR rate, no significant EFS benefit emerged, and OS was virtually identical.
🚨In an evolving perioperative MIBC landscape, KEYNOTE-866 does not support adding pembrolizumab to cisplatin/gemcitabine.

Statistical Considerations
Overall type I error rate controlled at α = 2.5% (1-sided) with graphical method of Maurer and Bretz
EFS (primary) 1-sided α = 0.025
→ 0.36 → pCR (key secondary) 1-sided α = 0
→ 0.64 → OS (key secondary) 1-sided α = 0
pCR ↔ OS: 1.0 / 1.0
IA2 was planned to occur when ~331 EFS events were observed (~60 months after first participant was randomly assigned)
OS and pCR rate were to be formally statistically tested only if the EFS null hypothesis was rejected
1) Trial design schema: Cohort 7 — SG + EV + zimberelimab in treatment-naive mUC · 2) Safety data: Cohort 7 — treatment exposure and safety (TEAEs/TRAEs) · 3) Response data: Cohort 7: SG + EV + zimberelimab in treatment-naive mUC - interim
The triplet of SG (TROP2 Topo1), EV (Nectin4/MMAE) and PD-1 triplet therapy has a response rate of 81% in 21 patients in advanced bladder cancer. Complimentary targets and payload make sense . These data should br taken forward in muscle invasive and advanced disease. Strategies to manage toxicity in bladder cancer is essential #ESMO26 @myESMO @OncoAlert

Conclusions
• SG + EV + ZIM showed manageable toxicity and tolerability over 12 months of median follow-up in participants with treatment-naive mUC
– No treatment-related deaths were observed
– Discontinuation rate due to TRAEs for any agent was 33% (highest rate was reported for EV)
– The overall safety findings were consistent with the established toxicity profiles of SG, EV, and ZIM
• SG + EV + ZIM demonstrated promising antitumor activity, with early and durable responses
– Objective response was achieved in 81% of the participants; median DOR was 16.7 months
– Median PFS was 19.3 months, and median OS was not reached
• These findings support further investigation of immunotherapy combinations that include ADCs with different mechanisms of action in patients with UC
– Ongoing Gilead-supported studies of SG in combination with immunotherapy include the phase 2 DAD/DAD-IO (NCT04724018) study sponsored by the DFCI, and the phase 3 ECOG-ACRIN EA8231 (NCT06524544) study

Sacituzumab Govitecan + Enfortumab Vedotin + Zimberelimab in Treatment-Naïve Metastatic Urothelial Cancer: Phase Ib Interim Results
🎤 Presented by @RandySweisMD 🇺🇸
@OncoAlert
🔬 Dual ADC targeting + PD-1 blockade: a promising new strategy in 1L metastatic urothelial cancer?
Combining two ADCs targeting different antigens (Trop-2 and Nectin-4) with distinct cytotoxic payloads (SN-38 and MMAE), plus PD-1 inhibition.
📊 STUDY DESIGN
Phase Ib | Cohort 7 | N=21
SG + EV + zimberelimab (ZIM)
Median follow-up: 12.2 months.
📊 KEY EFFICACY RESULTS
✅ Objective Response Rate: 81% (17/21)
• Complete responses: 14% (3/21)
• Partial responses: 67% (14/21)
• Clinical benefit rate: 86%
📈 Duration of Response
• Median DoR: 16.7 months
• 12-month DoR rate: 76%
• 82% of responders maintained response ≥6 months.
✅ Progression-Free Survival
• Median PFS: 19.3 months (95% CI 10.6–NE)
• 12-month PFS: 73%
📊 Overall Survival
• Median OS: Not reached.
⚠️ SAFETY
• Grade ≥3 treatment-emergent AEs: 67%
• Grade ≥3 treatment-related AEs: 52%
• Treatment-related discontinuation of ≥1 drug: 33%
• No treatment-related deaths.
⭐ MY POINT OF VIEW | CLINICAL PEARL
An 81% ORR with encouraging durability is a compelling signal—but response rates alone do not establish a new standard of care.
🔬 Dual ADC therapy introduces an intriguing strategy: targeting different antigens while delivering complementary cytotoxic payloads.
However, this is a small, single-arm phase Ib cohort (n=21), with substantial toxicity and limited follow-up.
💡 The critical question is not whether we can intensify EV-based therapy, but whether a third agent provides meaningful additional survival benefit without compromising tolerability or quality of life.
📌 Randomized trials are essential before challenging EV + pembrolizumab as the established 1L standard.

#ESMO26 Can two ADCs + IO push response rates even higher in 1L metastatic urothelial cancer?
🚨TROPHY-U-01 Cohort 7, evaluating sacituzumab govitecan + enfortumab vedotin + zimberelimab (N=21).
🔹 ORR 81%, including 14% CR
🔹 Median DOR 16.7 months
🔹 Median PFS 19.3 months
🔹 Median OS not reached
🔹 Grade ≥3 treatment-related AEs: 52%; 33% discontinued ≥1 agent
Impressive early activity from dual ADC targeting Trop-2 + Nectin-4, but the key question is whether the added efficacy justifies the toxicity over EV+pembrolizumab.

The KN905 MIBC trial includes a 3rd, less celebrated arm of single agent pembro. Results show pembro delivers an important contribution to the EVP. The trial is small and EVP performs better, but pCR rates for pembro of 35% are in the same range as neoadjuvant cisplatin chemo while EFS/OS HRs of 0.71/O.76 vs surgery are impressive. Pembro had about half the toxicity of EVP, underlining the relevance of therapy duration. VOLGA (3 cycles of EVD), is a half way between Pembro alone and 9 cycles of EVP. @Annals_Oncology #ESMO26 @Annals_Oncology @OncoAlert

Summary and Conclusions
- In this ad hoc analysis of participants with MIBC who were cisplatin-ineligible or cisplatin-declining and were concurrently randomized to all 3 KEYNOTE-905 study arms:
- EFS and OS favored perioperative EV + pembro compared with RC + PLND alone
- Perioperative pembro was associated with numerically better EFS and OS compared with RC + PLND alone
- pCR and pDS rates favored perioperative EV + pembro or pembro versus RC + PLND alone
- Safety results with perioperative EV + pembro or pembro were generally consistent with the known safety profiles of the individual drugs, the underlying disease and/or surgery, or the preexisting comorbidities within the study population
- The pattern of efficacy outcomes across all 3 KEYNOTE-905 study arms was consistent with a contribution of both EV and pembro to the observed activity of the perioperative EV + pembro regimen in participants with MIBC who are cisplatin-ineligible
- However, these observations should be interpreted with caution due to the ad hoc nature of this analysis
- Perioperative EV + pembro is approved for patients with MIBC irrespective of eligibility for cisplatin-based neoadjuvant therapy, representing a new standard of care in this setting

#ESMO26 How much does each drug contribute to perioperative EV + pembrolizumab in MIBC?
🚨A 3-arm analysis of KEYNOTE-905/EV-303 (N=255).
EV+P vs P alone vs surgery:
🔹 3-year EFS: 69.5% vs 49.6% vs 37.4%
🔹 pCR: 58.8% vs 25.3% vs 10.3%
🔹 Pathologic downstaging: 65.9% vs 33.7% vs 14.9%
🔹 EFS HR vs surgery: 0.40 with EV+P; 0.71 with P alone
📌The efficacy gradient suggests both EV and pembrolizumab contribute to the combination's activity, with substantially greater benefit from EV+P.
📌Important caveat: descriptive, ad hoc analysis without formal statistical testing.

Perioperative Pembrolizumab or Enfortumab Vedotin + Pembrolizumab in Cisplatin-Ineligible Muscle-Invasive Bladder Cancer: Ad Hoc Analysis
🎤 Presented by Anders Ullén 🇸🇪
@OncoAlert
🔬 What is the contribution of each agent to the benefit of perioperative EV + pembrolizumab?
📊 STUDY DESIGN
Exploratory 3-arm analysis | N=255
Patients with #MIBC ineligible for or declining cisplatin, concurrently randomized to:
🟢 EV + pembrolizumab (n=85)
🔵 Pembrolizumab alone (n=83)
🔴 Radical cystectomy + PLND alone (n=87)
📊 KEY RESULTS
✅ OVERALL SURVIVAL
🔹 EV + pembro vs control:
HR 0.48 (95% CI 0.29–0.80)
🔹 Pembro vs control:
HR 0.76 (95% CI 0.48–1.20)
📈 Median OS:
• EV + pembro: NR
• Pembro: 51.0 months
• Control: 41.7 months
✅ PATHOLOGICAL COMPLETE RESPONSE
🟢 EV + pembro: 58.8%
🔵 Pembro: 25.3%
🔴 Control: 10.3%
Absolute differences vs control:
• EV + pembro: +48.6 percentage points
• Pembro: +15.7 percentage points
📌 EFS and OS favored perioperative EV + pembro versus surgery alone, while pembrolizumab monotherapy showed numerically favorable outcomes.
⚠️ SAFETY
Grade ≥3 AEs:
• Neoadjuvant: 44.0% vs 20.7% (EV + pembro vs pembro)
• Adjuvant: 60.0% vs 44.9%
🔬 INTERPRETATION
The efficacy pattern supports a potential contribution of both EV and pembrolizumab.
However, this was an ad hoc exploratory analysis, and comparisons should not be interpreted as confirmatory evidence of the independent contribution of each drug.
⭐ MY POINT OF VIEW | CLINICAL PEARL
The question is evolving from whether perioperative EV + pembrolizumab works to understanding why the combination works—and which patients truly need both agents.
The striking pCR difference and favorable OS signal reinforce the biological rationale for combining an ADC with immune checkpoint inhibition.
💡 But treatment intensification must always be balanced against toxicity, patient fitness and long-term benefit.
📌 EV + pembrolizumab is an established perioperative option for cisplatin-ineligible MIBC based on the parent KEYNOTE-905 trial. These exploratory findings add insight rather than establish a new treatment indication.

• Randomization was 1:1
• Participants had to be cisplatin-ineligible
2020 — Third arm added:
• Perioperative EV + pembro with RC + PLND
• Randomization was updated to 1:1:1
2022 — Inclusion criteria updated to include participants who were cisplatin-eligible but declined cisplatin-based chemotherapy
2022 —
• Randomization to pembro with RC + PLND was stopped
• Randomization updated to 1:1 to perioperative EV + pembro with RC + PLND vs. RC + PLND alone
• Adjuvant nivolumab permitted in the RC + PLND alone arm when clinically indicated and regionally available

PEACE-1
Slide: conclusions (Karim Fizazi)
PEACE-1 at 7.7 years, de novo mCSPC: abiraterone added to ADT plus docetaxel with long term improves survival.
📈 Docetaxel population, n=710: OS HR 0.68, median 6.2 vs 4.4 years, 7-year OS 45.7% vs 30.7%
📊 OS HR was 0.75 at the 2022 analysis, so the effect grew with follow-up
🔍 86% of controls got an ARPI after progression. No long-term safety signal
Fizazi's point this investigator imitated trial gives us what few industry frontline trials by following patients this long.
#ESMO26 #ProstateCancer #mCSPC #GUonc
[Slide 4]
Conclusion: PEACE-1
• Survival is clearly improved by abiraterone in the long-term
• Almost twice more long-term survivors with triplet systemic therapy in subgroups !
• Triplet systemic therapy active regardless of metastatic « volume »
• Early is truly better in mCSPC
• Almost systematic use of an ARPI beyond progression in the control arm of PEACE-1
• No long-term safety signal

Kaplan-Meier survival data: rPFS de novo high vs low volume, room for improvement / poor responders
But 4 yrs on, maybe the debate isn't doublet vs triplet. It's what we do with poor responders. PSA >0.2 at ~6 months = major unmet need & opportunity. Good to see trials now focused here (PEACE-6 PR, TRIPLE-SWITCH, REINFORCE, EvoPAR-PR05), as Ursula Vogl discussed. #ESMO2026 2/2 https://t.co/96R7jvX9kK

• Potential benefit from early 177Lutetium-PSMA-6174,5
• Poor responders PSA > 0.2 ng/mL at nadir → clinical trial (e.g. PEACE-6 Poor Responders6, TRIPLE-SWITCH7, REINFORCE8, EvoPAR-PR059)

PROTEUS: A Significant Advance in Surgery Outcomes in HR LPC/LAPC but No Surgery-Alone Comparator
• In HR LPC/LAPC, despite refinement of prostatectomy as an SOC,1 the frequency of disease recurrence is high and patients may be subject to additional morbidity from subsequent therapy2,3
• The PROTEUS main study, with a blinded design, demonstrated superior efficacy of 1-year perioperative apalutamide plus ADT compared with an active comparator4:
Unprecedented Study Design
• Largest size to date
• Novel end points
• PSMA PET inclusion
Enhanced Disease Control With Perioperative Apalutamide + ADT
Significant benefit:
• 9x greater pCR/MRD
• 20% lower hazard for metastasis or death
• 29% lower risk of recurrence or death
• ~3 years longer time to next treatment
Limitation
Control group did not receive SOC (surgery alone)
The PROTEUS Substudy was designed to compare perioperative apalutamide + ADT with RP + PLND versus SOC (surgery alone)
ADT, androgen deprivation therapy; HR LPC/LAPC, high-risk localized/locally advanced prostate cancer; pCR/MRD, pathologic complete response/minimal residual disease; PLND, pelvic lymph node dissection; PSMA PET, prostate-specific membrane antigen positron emission tomography; RP, radical prostatectomy; SOC, standard of care.

PROTEUS Substudy Conclusions
• Together with the PROTEUS main study, the PROTEUS Substudy supports 1-year perioperative APA + ADT as a treatment option for patients with HR LPC/LAPC fit for surgery and systemic therapy
• Perioperative APA + ADT improves disease control and gives patients a longer time before starting subsequent therapy
Enhanced Disease Control With Perioperative APA + ADT
• 62% lower risk of recurrence or death
• 51% lower risk of death or developing metastases over time
• ~50% fewer patients starting subsequent therapy by ~3 years
• >3× longer time to first subsequent therapy

PROTEUS: a positive result, but significant limitations
EFS and MFS at 3 years median follow-up is too short
INITIAL STAGING | No baseline PSMA PET in a very-high-risk population
PRIMARY ENDPOINT | EFS includes biochemical failure during prolonged androgen suppression
MFS | PSMA PET-detected events complicate interpretation without baseline PET
TOXICITY | Significant increase in toxicity
COMPARATOR | RP alone versus multimodality care, or ADT +RT
Nicholas van As
[Slide 4]
Should practice change now?
I would not currently support perioperative apalutamide + ADT with radical prostatectomy in high-risk prostate cancer.
Longer follow-up, mature survival data and outcomes after salvage treatment are needed before changing practice.

CAPItello-281 updated DCO: Conclusions
• In CAPItello-281, ~25% of tested patients had PTEN-deficient tumours
• A clinically meaningful improvement in OS (42% maturity) was observed for capi + abi vs pbo + abi (HR 0.82, 95% CI 0.68, 0.99; median OS: 57.4 vs 46.5 months)
• rPFS and SSE-FS outcomes were consistent with the primary analysis and continued to favour capi + abi
• The safety profile remained consistent with the primary analysis
– Most common AEs were on-target diarrhoea, rash and hyperglycaemia
These updated results support capivasertib plus abiraterone as a first-in-class treatment for this PTEN-deficient mHSPC population (high- and low-volume disease) with poor prognosis

Slide: Cross-trial comparison table of perioperative IO in MIBC: ENERGYZE, KN866
It hard to explain why 1 trial with gem/cis +/-PD(L)1 (NIAGARA) is +ve for EFS/OS and 2 very similar trials (presented today) are negative in MIBC. Potentially NIAGARA has the highest risk population, not all respond to IO and the maintenance phase the most effect- but the OS of gem/cis pembro HR of 1 is concerning. This reflects what we saw in metastatic disease with contradictory results for the big combination trials. Overall EVP looks better and more consistent #ESMO26 @myESMO @Annals_Oncology @OncoAlert

How I explain these two studies
• More similarities than differences with NIAGARA
• Patient mix had better than expected prognosis
- this makes it harder to demonstrate modest improvement
• Small imbalances, unseen at baseline, may explain different findings between the trials

#ESMO26 | VOLGA | Presidential Symposium-1
In cisplatin-ineligible/refusing MIBC, neoadjuvant EV + perioperative durvalumab significantly improved EFS and OS vs the control arm.
EFS: HR 0.55 (24-month: 78% vs 69%)
OS: HR 0.58 (24-month: 83% vs 75%)
pCR: 45% vs 10%
Impressive results!
Unlike KEYNOTE-905/EV-303, EV was administered only in the neoadjuvant setting, with no adjuvant EV.
I’m looking forward to the discussion during the session.
Context: the LBA2 abstract in this post reports, for D+EV vs control, EFS HR 0.51 (0.38-0.67) with 24-month EFS 64% vs 45%, and OS HR 0.58 (0.40-0.83) with 24-month OS 78% vs 69% (VOLGA pre-planned interim analysis, data cutoff 2 Mar 2026).

LBA2 - Perioperative durvalumab with or without tremelimumab plus neoadjuvant enfortumab vedotin in muscle-invasive bladder cancer: Results from the phase 3 VOLGA trial
Speakers Thomas B. Powles (London, United Kingdom)
Lecture Time 16:54 - 17:06
Abstract
Background
The standard of care continues to evolve for patients (pts) with muscle-invasive bladder cancer (MIBC). We evaluated if neoadjuvant durvalumab (D) ± tremelimumab (T) plus enfortumab vedotin (EV) followed by radical cystectomy (RC) and adjuvant D±T would be an effective option.
Methods
VOLGA (NCT04960709), a phase 3, randomised, open-label trial, enrolled pts with MIBC (cT2-T4aN0/1M0 or cT1N1M0) ineligible for or who refused treatment (tx) with cisplatin and were planned for RC. Pts were randomised 1:1:1 to D+EV, D+T+EV, or control. D+EV and D+T+EV arms: perioperative D±T (neoadjuvant: 3 cycles of D, 2 cycles of T; adjuvant: 9 cycles of D, 1 cycle of T) and 3 cycles of neoadjuvant EV; RC was completed after neoadjuvant tx. Control arm: RC and observation or locally approved adjuvant tx. Dual primary endpoints were event-free survival (EFS): D+EV vs control and D+T+EV vs control. Overall survival (OS) was the key secondary endpoint. Safety was also assessed. Here we present results from a pre-planned interim analysis (data cutoff: 02 Mar 2026).
Results
Overall, 233, 233, and 229 pts were randomised to the D+EV, D+T+EV, and control arms, respectively. RC was completed in 85% (D+EV), 79% (D+T+EV), and 78% (control) of pts; and 55% (D+EV) and 42% (D+T+EV) completed adjuvant tx. Median EFS follow-up was 22.9 mo. D+EV showed significant improvements in EFS (HR 0.51 [95% CI, 0.38–0.67], P<0.0001; 24-mo rate 64% vs 45%) and OS (HR 0.58 [95% CI, 0.40–0.83], P=0.0027; 24-mo rate 78% vs 69%) vs control. D+T+EV also showed a significant improvement in EFS vs control (HR 0.61 [95% CI, 0.47–0.80], P=0.0004; 24-mo rate 60% vs 45%) but did not meet significance for OS; follow-up is ongoing. Pathological complete response per local review was observed in 45% (95% CI, 38.6–51.7) of pts in the D+EV arm and 10% (95% CI, 6.1–14.2) in the control arm. In the D+EV and D+T+EV arms, max. Grade 3/4 tx-related adverse events occurred in 30% and 42% of pts, respectively. ctDNA results will also be presented.
Conclusions
Dual primary endpoints of EFS were met. Perioperative D plus 3 cycles of neoadjuvant EV also demonstrated a significant improvement in OS vs control. Safety profiles were consistent with those of the individual agents.

🔬 Why did NIAGARA succeed while KEYNOTE-866 and ENERGIZE failed to meet their primary efficacy endpoints?
📊 EFS HR:
✅ NIAGARA: 0.68
❌ KEYNOTE-866: 0.88
❌ ENERGIZE: 0.94
🧩 Different populations, baseline risks, eligibility criteria and trial designs complicate comparisons.
⭐ MY POINT OF VIEW
Different outcomes across trials do not establish superiority of PD-L1 over PD-1 blockade.
💡 In curative-intent MIBC, patient selection, endpoint definitions and absolute clinical benefit matter as much as the HR.
Cross-trial comparisons generate hypotheses, not definitive conclusions.

KEYNOTE-866 • ENERGIZE • TROPHY-U-01
🎤 Prof. Robert Jones 🇬🇧
@OncoAlert @urologysummit
🔬 Why do apparently similar trials produce different outcomes?
An excellent critical appraisal of perioperative immunotherapy in #MIBC and emerging triplet strategies in metastatic #UrothelialCancer.
📊 1️⃣ PERIOPERATIVE IMMUNOTHERAPY
✅ NIAGARA: EFS HR 0.68
❌ KEYNOTE-866: EFS HR 0.88
❌ ENERGIZE: EFS HR 0.94
But are these trials directly comparable?
📌 Important baseline differences:
• T2 disease: 40% vs 15% vs 76%
• 24-month control-arm EFS: 59.8% vs 70% vs 71.6%
Different populations, endpoints and statistical designs complicate cross-trial interpretation.
🧬 2️⃣ ctDNA: PROGNOSTIC ≠ PREDICTIVE
Pretreatment ctDNA positivity was associated with shorter EFS and OS.
⚠️ In ENERGIZE, baseline ctDNA positivity differed between arms (59% vs 51%), potentially introducing prognostic imbalance.
🔬 ctDNA clearance before cystectomy identified patients with more favorable outcomes.
But can ctDNA clearance identify candidates for bladder preservation?
Not yet! Prospective validation is essential before considering omission of radical cystectomy.
💊 3️⃣ DUAL ADC + IMMUNOTHERAPY: THE NEXT FRONTIER?
TROPHY-U-01 Cohort 7:
✅ ORR 81%
✅ Median PFS 19.3 months
✅ Median DoR 16.7 months
⚠️ Grade ≥3 treatment-related AEs: 52%
⚠️ Treatment-related discontinuation of ≥1 agent: 33%
Promising efficacy, but only 21 patients and no randomized comparator.
⭐ MY POINT OF VIEW CLINICAL PEARLS
🔹 A positive trial does not prove the superiority of one checkpoint inhibitor over another.
🔹 ctDNA may redefine risk stratification, but molecular clearance is not yet a license to omit surgery.
🔹 Dual ADC intensification is scientifically exciting, but added efficacy must justify added toxicity.
💡 The future of GU oncology is not about treating everyone more aggressively. It is about treating the right patient with the right strategy, at the right time.
📌 PRACTICE IMPLICATION
These new results do not independently establish a new standard of care. Individual trials must be interpreted on their own merits.
Access also matters: perioperative gemcitabine/cisplatin + durvalumab remains an important option where EV + pembrolizumab is unavailable.

1) Slide: Cross-trial table: VOLGA vs KEYNOTE-905/EV-303 · 2) Kaplan-Meier survival data — KEYNOTE-B15 / EV-304, KEYNOTE-905 / EV-303 · 3) Slide: VOLGA design + EFS/OS curves recap · 4) Kaplan-Meier survival data: EFS and pCR in VOLGA
#ESMO26 Dr. Michiel van der Heijden discussed the implications of VOLGA alongside KEYNOTE-905 and KEYNOTE-B15:
🔹 EV + durvalumab doublet: EFS HR 0.51; OS HR 0.58, a 42% reduction in the hazard of death.
🔹 Triplet (+ tremelimumab): EFS HR 0.61; OS not yet significant. More toxicity, without a demonstrated advantage from CTLA-4 blockade.
🔹 Crucial difference: VOLGA used only 3 neoadjuvant cycles of EV, followed by RC and adjuvant durvalumab, without adjuvant EV.
🔹 The unresolved question: Which patients need adjuvant therapy? pCR is informative, but does not guarantee eradication of micrometastatic disease.
🚨Key message: The doublet is the regimen most likely to move forward. The next breakthrough may come from response-adapted treatment, not adding another drug.

CONCLUSION
- WES revealed distinct somatic alteration profiles between cisplatin-naive (primary tumors) and cisplatin-exposed (metastatic) TGCT samples
- Significant proportion of somatic variants present in cfDNA at diagnosis was detectable in metastases and not in primary tumors, highlighting the potential of liquid biopsy for early identification of metastasis-associated molecular alterations.
INTRODUCTION
[...]h testicular germ cell tumors (TGCTs) respond well to cisplatin (cDDP)-based chemotherapy. [...] develop cDDP resistance, resulting in treatment failure with no effective alternative treatments [...] molecular mechanisms underlying cDDP resistance and TGCT pathogenesis remain incompletely [...] this issue, we performed whole-exome sequencing (WES) of primary tumors, metastases and [...] samples from patients with advanced TGCTs to identify genetic alterations that may contribute [...] and therapy resistance.
MATERIALS AND METHODS
Sample characteristics: Primary tumors 25; Metastases 7; cfDNA from diagnosis 6; gDNA (background control) 25
Whole exome sequencing
- Library preparation: SureSelect XT HS Human All Exon + SureSelect XT HS Reagent kits (Agilent)
- Sequencing: Illumina platform (NextSeq500, 2000)
- Sequencing depth = 50 million read pairs/sample
- Target mean coverage = 100x
Variant filtering
- Minimum tumor sequencing depth: >=15x
- Minimum alternative allele depth: >=10x
- Variant allele frequency (VAF): >=5%
- Exclusion of variants detected in matched germline
- Exclusion of non protein-altering variants
- Selection of genes with qualifying alterations in >=3 of 25 patients for primary tumor analysis and >=2 of 7 patients for metastasis analysis
- Evaluation of candidate genes based on their biological function, recurrence of detected variants across patient samples and their predicted functional consequences

Pembrolizumab Adds to EV Perioperatively
EV + Pembro Outperforms Either Drug Alone (EV-103 Cohort K, EV-303)
EV-103 cohort K: EV + pembro > EV alone
Longer PFS (median NR vs 8.0 mo) -> justified the combo in EV-302
Progression-free survival - EV + pembro (n = 76): median NR; EV monotherapy (n = 73): median 8.0 mo
Overall survival - EV + pembro (n = 76): median 22.3 mo; EV monotherapy (n = 73): median 21.7 mo
EV-303: EV + pembro > pembro alone > RC alone
EFS HR 0.40 vs 0.71; combo now standard for cisplatin-ineligible MIBC
Event-free survival - HR vs. control (95% CI)*: EV + pembro 0.40 (0.25-0.65) - Pembro 0.71 (0.47-1.07)
EFS landmarks (12 / 24 / 36 mo): EV + pembro 77.2% / 75.8% / 69.5%; Pembro 66.4% / 55.8% / 49.6%; RC + PLND 55.0% / 41.0% / 37.4%
Overall survival - HR vs. control (95% CI)*: EV + pembro 0.48 (0.29-0.80) - Pembro 0.76 (0.48-1.20)
OS landmarks (12 / 24 / 36 mo): EV + pembro 83.3% / 78.4% / 74.5%; Pembro 78.2% / 66.9% / 61.4%; RC + PLND 74.6% / 62.6% / 55.7%

Authors' conclusions
- ctDNA is strongly prognostic in both arms: ctDNA- -> better EFS and pCR
- EV + pembro beat cis + gem on EFS regardless of ctDNA status
- Clearance by presurgery -> better EFS; more frequent with EV + pembro
- Among clearers, EV + pembro still had better EFS
ctDNA-negative status was linked to better outcomes in both arms
Higher pCR at baseline and presurgery; longer EFS at baseline and postsurgery (exploratory analysis)

BACKGROUND [partially obscured by presenter]
RESULTS
Among 608 pts included in phase 1 trials at DITEP between September 2024 and November 2025, 431 with evaluable PRO-CTCAE data were included in the analysis. Median number of completed questionnaire was 11 [95% CI, 10-30].
Population, n (%): n 431; Age, median [Q1,Q3] 62.0 [54.0,69.0]; Gender: Female 242 (56.1), Male 189 (43.9); Cancer stage: Localized 10 (2.3), Locally advanced 29 (6.7), Metastatic 392 (90); [Type] of drug: Targeted therapy (TT) 182 (42.2), Immunotherapy (IO) 156 (36.2), ADC 68 (15.8), IO+ Chemo 10 (2.3), IT IO 6 (1.4), IO + RT 3 (0.7), IO + TT 3 (0.7), IO + ADC 1 (0.2), Radioligand 1 (0.2), TT + RT 1 (0.2)

- DLT rate was 4.6% (n=20) with a median time to DLT of 14 days [95% CI, 7-21] among pts with a DLT. 12.5% pts had a dose interruption, 8.4% a dose reduction and 6.5% discontinued treatment due to toxicity making a total of 90 tolerability events (20.9%). Median time to tolerability event was 42 days [95% CI, 31-63] among pts with a TE.
- Grade >=3 PRO-CTCAE events occurred earlier, preceding tolerability events by a median of 11 days [95% CI, 8-21] and DLTs by 2.5 days [95% CI, -3 to 12].
- Incorporating grade >=3 PRO-CTCAE data improved prediction of safety/tolerability events (AUROC 0.65 vs. 0.61). The PRO-CTCAE G>=3 flag was an independent predictor beyond clinical variables (adjusted OR 5.9 [95% CI, 2.2-15.5], p<0.001).
Figure 4: Mean cross-validated AUROC (±1 SD) of the model including the PRO-CTCAE G>=3 flag (ablative analysis)
[CONC]LUSION: [PRO]-CTCAE events preceded tolerability events and added independent predictive information beyond clinical variables (adjusted OR 5.9). Continuous PRO-CTCAE monitoring [...] both earlier and complementary toxicity signals to refine dose-escalation decisions and RP2D identification.

INTRODUCTION
The prognostic impact of molecular features in de novo metastatic (M1) hormone-sensitive prostate cancer (mHSPC) remains largely underexplored in real-world settings.
The Decipher Genomic Classifier (GC) predicts benefit from docetaxel (Grist et al., Cell 2025; Sweeney et al., ASCO 2026). In addition, PEACE-1 data showed that approximately 25% of de novo mHSPC presented neuroendocrine markers on IHC (Pobel et al., ESMO 2024), suggesting that transcriptomic features beyond GC may carry prognostic information.
Objective: to evaluate the prognostic value of GC and of validated gene expression signatures for overall survival in a large real-world cohort of de novo mHSPC, independently of clinical variables.
METHODS
Population. US patients with a diagnosis of prostate cancer (PCa) and a GC test performed on the diagnostic biopsy, with metastases diagnosed within 90 days before or after the PCa diagnosis (de novo M1).
Data. Clinical outcomes were obtained by linkage to electronic health record data. Transcriptome-wide gene expression profiling was performed in a clinical laboratory (Veracyte, San Diego, CA).
Signatures. GC and validated signatures: AR activity, small cell/NE-like, PTEN, TP53, PAM50, PSC; MKI67 and individual AR-dependent and NE-related genes.
Statistics. Associations with overall survival (OS) from diagnostic biopsy were assessed using Cox proportional hazards models, with GC and signatures dichotomized using published thresholds, MKI67 and individual genes as top 20% vs bottom 80%. Multivariable analyses (MVA) were adjusted for age, T stage, Gleason grade group and PSA. OS was estimated using the Kaplan-Meier method and compared with the log-rank test.
RESULTS
1 2,303 de novo mHSPC patients: aggressive disease, most with high-risk GC
209,649 pts with PCa and GC testing -> 2,303 pts (1.1%) with de novo M1 disease (M1 within 90 days of PCa diagnosis)
Most patients had aggressive disease: 55% had Gleason grade group 4-5 and 76% had high-risk GC, including 55% very high risk (score >0.85). A small cell NE-like transcriptomic signature was found in 6% of tumors.
2 Higher GC is independently associated with worse OS
On MVA, higher GC was independently associated with worse OS (HR 1.37 per 0.1-unit increase; p<0.001). Very high vs lower GC risk conferred a 3-fold increased risk of death (HR 3.31; p<0.001).
3 GC and TP53 combine to identify the highest-risk patients
Combined GC risk (very high vs lower) and TP53 stratification demonstrated incremental risk, with 5-year OS rates of 93.3% for lower GC + wildtype, 93.3% for lower GC + mutant, 67.6% for very high GC + wildtype, and 58.7% for very high GC + mutant.
4 NE-like, TP53, PTEN, MKI67 and low AR activity signatures predict worse OS
On MVA, the small cell NE-like signature (HR 2.57; 95% CI 1.56-4.24), the TP53 mutant signature (HR 2.31; 1.47-3.63), the PTEN inactivity signature (HR 1.58; 1.06-2.36), lower AR activity (HR 2.37; 1.61-3.48) and higher MKI67 expression (top 20%; HR 1.82, 1.24-2.67) were associated with worse OS. No deaths among the 30 patients (1%) classified the NE classified according to Beltran [partially obscured]
5 Neuroendocrine marker expression is associated with worse OS
On MVA, high KLK2 expression was associated with better OS (HR 0.46; 95% CI 0.25-0.87). Among NE-related genes, high DLL3 (HR 1.54; 1.03-2.30), CEACAM5 (HR 1.63; 1.08-2.47) and EZH2 (HR 1.55; 1.04-2.32) expression were associated with worse OS. Chromogranin A, SEZ6, INSM1 and synaptophysin showed similar trends (HR 1.12-1.37) without reaching significance.

BACKGROUND
In advanced thoracic malignancies, liquid biopsy (LB) accelerates molecular diagnosis and treatment initiation. Since its sensitivity remains variable and concurrent tissue NGS (tNGS) raises cost-efficiency concerns, identifying clinical predictors of LB positivity is essential to define when LB alone may suffice.
Can we predict, using baseline clinical features available at first visit, which patients are likely to have an informative baseline LB?
METHODS
We retrospectively included patients with advanced thoracic malignancies and available baseline LB at Gustave Roussy (2021-2026). LB samples were analysed through FoundationOne Liquid CDx. Baseline clinical features (age, sex, smoking habit (pack-years), stage at diagnosis, metastatic burden/sites, ECOG PS) were analysed through multivariable logistic regression. The predictive model was developed using clinically plausible variables and internally validated using bootstrap optimism correction.
RESULTS
516 baseline available LBs; 71 (14%) non-informative -> Multivariable logistic regression -> Predictive model development (variables: sex, pack-years, PS, stage at diagnosis, liver and bone metastases) -> Discrimination and internal validation (complete-case analysis on 417 patients) -> Potential clinical impact (using a >=90% predicted probability threshold)
INDEPENDENT PREDICTORS [forest plot, Multivariable logistic regression; odds ratio values small/partly illegible]: Age 1.00 (0.97-1.03), p = 0.927; Female 0.48 (0.25-0.94), p = 0.031; Pack-years 1.03 (1.01-1.05), p = 0.001; PS 2-4 2.46 (0.96-6.18), p = 0.055; Stage IV at diagnosis 1.48 (0.67-3.29), p = 0.333; N. of metastatic sites 1.02 (0.75-1.39), p = 0.890; Liver metastases 3.12 (0.97-10.04), p = 0.057; Brain metastases 1.45 (0.70-2.98), p = 0.320; Bone metastases 2.46 (1.14-5.33), p = 0.022
PREDICTIVE MODEL DISCRIMINATION [ROC curve]: Apparent AUC = 0.763 (95% CI 0.700-0.825); Optimism-corrected AUC = 0.736 (95% CI 0.675-0.800)
PREDICTIVE MODEL CALIBRATION [calibration plot]: Apparent; Optimism-corrected = 0.87; O/E = 1.00
CLINICAL IMPACT
417 patients included
Predicted probability >=90% n = 216 (52%) -> Liquid biopsy first -> 11/216 (5.1%) Non-informative LB (missing one KRAS non-G12C mut and one ROS1 fusion); 205/216 (PPV 94.9%) True informative LB -> 49% Potential reduction in concurrent tissue NGS (205/417)
Predicted probability <90% n = 201 (48%) -> Liquid biopsy + tissue NGS
CONCLUSION
A simple prediction model using clinical features available at first oncology visit may identify pts with high probability of informative LB, potentially sparing more than 40% of concurrent tNGS and optimizing resources.

EARLY PSA ASSESSMENT
At 6 months, PSA remained low in both arms: SOC + MDT median 0 (mean 0.3) vs SOC alone median 0 ng/mL (mean 0.1); n=525, p=0.27
CONCLUSION
No apparent excess of high-grade acute toxicity was observed with SBRT. Longer follow-up is required to determine efficacy.

Ternary Complex Formation: AR-JNJ-6143-BRD4
JNJ-6143 selectively binds AR and BRD4
Ternary complex sequesters and functionally inactivates BRD4
BRD4 cannot engage chromatin to drive transcription → Apoptosis
• Selectively binds AR and BRD4, resulting in BRD4 loss of function and death in PC cells1-3
• Induces tumor regression across preclinical in vivo CRPC models with AR and non-AR alterations2,3
• Preliminary phase 1 data suggest a favorable safety profile with evidence of tumor shrinkage and PSA decline in patients with mCRPC3

Slide: Best Poster: MIBC patients declining radical cystectomy - outcomes by cCR
This further #ESMO26 @ESMO_Open simultaneous publication is very important for me. @SanRaffaeleMI @MyUniSR
Outcomes of pts with MIBC who decline RC in perioperative setting:
Take-home message:
1. cCR (Milan criteria) is a reliable biomarker and indicator of outcomes with Systemic Rx and reTURBT

CONCLUSIONS
Patients with ypT0Nx at reTURBT achieved 24-month MFS and OS >95%, comparable to those with ypT0N0 after RC, supporting biopsy-confirmed cCR (Milan criteria) as a [cr]iterion for bladder preservation.

Slide: European Urology Oncology paper header: bladder-sparing vs early RC in cT1 micropapillary
In 2006 we reported 44 patients with non-muscle-invasive micropapillary bladder cancer treated at MD Anderson. 27 got BCG. At a median 30 months, only 5 of them were disease-free with their bladder in place.
Twenty years on, we went back to the literature to ask whether that picture still holds. New meta-analysis in @EurUrolOncol

Background
• Maintenance avelumab after platinum-based chemotherapy is standard of care in advanced urothelial cancer.
• A substantial proportion of patients never start planned maintenance treatment.
• Factors associated with failure to receive avelumab and the impact of the switch on quality of life (QoL) remain poorly characterised in prospective datasets.
Methods
• Exploratory, descriptive analysis from DISCUS (NCT06892860): investigator-initiated, international, randomised phase II trial.
• Randomisation to 3 (3C) or 6 (6C) cycles of gemcitabine plus cisplatin or carboplatin. Patients without progression received avelumab.
• PROs: EORTC QLQ-C30 GHS/QoL at baseline and relevant post-chemotherapy assessment (C4D1 for 3C and C7D1 for 6C). The pre- and post- immunotherapy GHS/QoL was restricted to patients who had avelumab (baseline and C7D1 for 3C and C9D1 for 6C).
[Three cycles] increased transition to avelumab
[bar chart partially obscured: 3C ...(74%) | 19 (15%) | 13 (10%); 6C ... | 40 (33%) | 12 (10%); legend: ...ce avelumab / ...ression / death / ...ity / patient / investigator decision]

*Multiple adverse events per patient therefore number of events used as denominator
QoL deterioration during chemotherapy identifies patients who will not reach avelumab
• GHS/QoL declined with 6C of chemotherapy but not with 3C
• Transition to avelumab was associated with stable QoL in both arms
[Bar chart, mean change in GHS/QoL from baseline: 3C + avelumab +2.0; 3C no avelumab -9.8; 6C + avelumab -4.6; 6C no avelumab -10.0; group n values illegible]
Shaded area = clinically meaningful decline (beyond -9 points). Arrow = 95% CI extending beyond the axis [rest illegible]
Patients who did not reach avelumab had poor outcomes: median PFS 3.9 and OS 7.5 months
PFS: HR 0.13 (95% CI: 0.08-0.20); legend: 3/6 cycles chemotherapy + avelumab; 3/6 cycles chemotherapy; x axis Time from Randomisation (months)
OS: HR 0.22 (95% CI: 0.13-0.35); legend: 3/6 cycles chemotherapy + avelumab; 3/6 cycles chemotherapy; x axis Time from randomisation (months)
Conclusions
• 34% of eligible patients never received avelumab, their outcomes were poor and only 27% received subsequent therapy.
• 3C increased transition to avelumab (74% vs 57%), driven by fewer progression/death events (15% vs 33%). Once avelumab started, QoL did not deteriorate further.
• Only baseline ECOG PS differed among patients who did and did not get avelumab.

BACKGROUND
• Nivolumab + ipilimumab (NIVO+IPI) is a standard first-line treatment for metastatic renal cell carcinoma (mRCC).
• Despite durable responses in many patients, >20% experience primary progressive disease (PPD) at first restaging.
• This study evaluated clinical factors and transcriptomic correlates associated with PPD.
METHODS
Clinical analysis | IMDC
1 Study population: IMDC real-world patients receiving first-line NIVO+IPI (n = 1,601).
2 Response definition: PPD = best overall response of PD per physician-assessed RECIST 1.1.
3 Statistical analysis: Multivariable logistic regression of baseline factors (evaluable n = 1,339).
Endpoint Definitions
•Time to Next-Line Therapy or Death (TNTD): Time from index date to next-line therapy or death.
•Mortality Without Next-Line Therapy (MWNT): Death before initiation of next-line therapy.
•Overall Survival (OS): Time from index date to death from any cause
Exploratory RNA-seq | COSMIC-313
1 Transcriptomic cohort: COSMIC-313 placebo + NIVO+IPI arm: 38 PPD vs 70 CR/PR (n = 108).
2 Differential expression: DESeq2 with adjustment for liver metastasis status.
3 Pathway enrichment: GSEA using MSigDB Hallmark gene sets.
Two complementary cohorts • Clinical associations and exploratory biology

[City of Hope logo]
Background
• Ongoing trials for mRCC are investigating novel inhibitors of GPR65 and HPK1 (MAP4K1), ENPP3xCD3 T cell engagers (TCEs), and CAR-T cells targeting CD70.
Methods
• Normalized RNA-sequencing gene expression data from IMmotion151, JAVELIN Renal 101, and HCRN-GU16-260 were analyzed.
• Gene co-expression was assessed using Pearson correlation coefficients.
• Patients were stratified into high/low expressors by median gene expression within each cohort.
• TME phenotypes were defined using NMF clusters and compared using ANOVA and chi-square tests.(1)
• PFS was analyzed using KM methods.
Results: gene co-expression
GPR65 and HPK1 (MAP4K1) were co-expressed with PDCD1, CTLA4 and CD274; ENPP3 and CD70 with KDR, EPAS1 and VEGFA in IMmotion151.
[Correlation heatmap: CTLA4, TIGIT, LAG3, PDCD1, MAP4K1, PTPN22, GPR65, CD274, MTOR, HAVCR2, CD70, ENPP3, VEGFA, EPAS1, KDR]
Results: GPR65, HPK1 (MAP4K1)
GPR65 and HPK1 (MAP4K1) were more highly expressed in patients bearing an immunogenic profile, defined by NMF cluster 4 in IMmotion151, p<0.05 for both.
[Stacked bar charts: Relative Abundance of NMF clusters, GPR65high/low, MAP4K1high/low]
Increased GPR65 and HPK1 (MAP4K1) expression were associated with prolonged PFS to IO-containing regimens (HCRN-GU16-260, JAVELIN Renal 101, respectively), p<0.05.
[KM panels: PFS - Nivolumab (GPR65 High/Low); Axitinib/Avelumab (MAP4K1 High/Low); number-at-risk rows small]
Results: ENPP3, CD70
ENPP3 and CD70 were more highly expressed in patients bearing an angiogenic profile, defined by either NMF clusters 2-3 in IMmotion151, p<0.05 for both.
[Stacked bar charts: ENPP3high/low, CD70high/low]
Increased ENPP3 and CD70 expression were associated with prolonged PFS to sunitinib (IMmotion151), (p=0.057, p=0.002, respectively).
[KM panels: Sunitinib (ENPP3 High/Low); Sunitinib (CD70 High/Low)]
Conclusions
• Emerging therapeutic targets in mRCC appear to have distinct associations with either angiogenic or immunogenic subtypes of the disease.
• Given ongoing trials with small molecules, TCEs and CAR-T approaches directed at these entities, our data inform combinatorial strategies for their use in mRCC.

Background
• Ongoing trials for mRCC are investigating novel inhibitors of GPR65 and HPK1 (MAP4K1), ENPP3xCD3 T cell engagers (TCEs), and CAR-T cells targeting CD70.
Methods
• Normalized RNA-sequencing gene expression data from IMmotion151, JAVELIN Renal 101, and HCRN-GU16-260 were analyzed.
• Gene co-expression was assessed using Pearson correlation coefficients.
• Patients were stratified into high/low expressors by median gene expression within each cohort.
• TME phenotypes were defined using NMF clusters and compared using ANOVA and chi-square tests.(1)
• PFS was analyzed using KM methods.
Results: gene co-expression
GPR65 and HPK1 (MAP4K1) were co-expressed with PDCD1, CTLA4 and CD274; ENPP3 and CD70 with KDR, EPAS1 and VEGFA in IMmotion151.
[Correlation heatmap: CTLA4, TIGIT, LAG3, PDCD1, MAP4K1, PTPN22, GPR65, CD274, MTOR, HAVCR2, CD70, ENPP3, VEGFA, EPAS1, KDR]
Results: GPR65, HPK1 (MAP4K1)
GPR65 and HPK1 (MAP4K1) were more highly expressed in patients bearing an immunogenic profile, defined by NMF cluster 4 in IMmotion151, p<0.05 for both.
[Stacked bar charts: Relative Abundance of NMF clusters, GPR65high/low, MAP4K1high/low]
Increased GPR65 and HPK1 (MAP4K1) expression were associated with prolonged PFS to IO-containing regimens (HCRN-GU16-260, JAVELIN Renal 101, respectively), p<0.05.
[KM panels: PFS - Nivolumab (GPR65 High/Low); Axitinib/Avelumab (MAP4K1 High/Low); number-at-risk rows small]
Results: ENPP3, CD70
ENPP3 and CD70 were more highly expressed in patients bearing an angiogenic profile, defined by either NMF clusters 2-3 in IMmotion151, p<0.05 for both.
[Stacked bar charts: ENPP3high/low, CD70high/low]
Increased ENPP3 and CD70 expression were associated with prolonged PFS to sunitinib (IMmotion151), (p=0.057, p=0.002, respectively).
[KM panels: Sunitinib (ENPP3 High/Low); Sunitinib (CD70 High/Low)]
Conclusions
• Emerging therapeutic targets in mRCC appear to have distinct associations with either angiogenic or immunogenic subtypes of the disease.
• Given ongoing trials with small molecules, TCEs and CAR-T approaches directed at these entities, our data inform combinatorial strategies for their use in mRCC.

Background
• Despite advancements in the treatment of metastatic renal cell carcinoma (mRCC), there are few treatments in the immunotherapy (IO) refractory setting.
• Preclinical studies have shown that PCSK9 inhibition combined with IO stunt tumor growth in multiple solid tumor models by downregulating MHC-1 expression and tumor antigen presentation, independent on its effect on cholesterol (Figure 1).1
• PCSK9 inhibition combined with IO has been shown to improve overall survival in patients with metastatic solid tumors (Figure 2).2
• We conducted an investigator-initiated trial combining PCSK9 inhibitor evolocumab with IO nivolumab in IO-refractory mRCC, BOOST-RCC (NCT06284564).
Figure 1 [PCSK9 pathway diagram]
Figure 1. Depiction of PCSK9 pathway for MHC-I expression1. MHC-1 is degraded in presence of PCSK9. When PCSK9 is absent or inhibited, MHC-1 is recycled, resulting in higher tumor antigen presentation and T-cell activation.

Methods
• BOOST-RCC is an investigator-led, phase 2 clinical trial which enrolled patients at MD Anderson and UT Southwestern between June 2024 and February 2025.
• A Simon 2-stage design was used with 10 patients in the first cohort. Stage 1 would be passed if >1/10 patients had an objective response.
• Patients were treated with evolocumab, a PCSK9 inhibitor, and nivolumab every 4 weeks and median follow up was 18 months.
• Circulating tumor cells (CTCs) were captured on a dendrimer-based device3, and HLA detected by cell surface immunofluorescence at baseline and on-treatment timepoints. Plasma PCSK9 and cytokines were measured via Multiplex ELISA. LDL and cholesterol were measured as standard of care testing.
• Paired, two-tailed t-tests with Welch corrections were performed. All timepoints were compared to baseline.

Conclusions
• In the BOOST-RCC trial, 9 of 10 patients experienced progression of disease.
• One patient (patient 9) with multiple lines of prior treatment had stable disease for 14 months, with a 16% decrease in target lesions and on-target effect of increased HLA expression on CTCs.
• The most common related grade 3 adverse events were fatigue (1) and elevated AST(1). There were no trial limiting toxicities.
• Evolocumab combined with nivolumab had on-target effects with significant decrease in plasma LDL and cholesterol and significant increase of plasma PCSK9 on treatment.
• Given no objective response to PCSK9 and nivolumab in this first stage population, this trial was stopped for further recruitment. This highlights heterogeneity of IO resistance in IO-refractory mRCC.

No PSMA PET at diagnosis
EAU and ESMO recommendations for initial staging of prostate cancer
INITIAL STAGING BY RISK CATEGORY
Low / favourable intermediate: No routine metastatic imaging
Unfavourable intermediate: Consider PSMA PET/CT
High risk / locally advanced: PSMA PET/CT if available
WHY PSMA PET?
proPSMA: staging accuracy 92% PSMA PET vs 65% CT + bone scan
More sensitive detection of nodal and distant disease before radical treatment
PROTEUS enrolled conventionally staged M0 patients without baseline PSMA PET.
Nicholas van As
[Slide 2]
Progression or delayed detection?
Baseline conventional imaging, but PSMA PET used to identify subsequent events
BASELINE: CONVENTIONAL IMAGING | FOLLOW-UP: PSMA PET
CT + bone scan M0 → Occult PSMA-avid micrometastasis → PSMA PET positive "MFS event"
Two biologically different possibilities can produce the same observed event:
A. Truly new metastatic progression
B. Pre-existing disease first detected later
Without baseline PSMA PET, these cannot reliably be distinguished.
~70% of RP patients with PSMA PET-detected relapse had persistent PSA.

One year of APA+ADT comes with toxicity, and outcomes after control-arm salvage aren't shown. His view: follow-up too short; would not yet support perioperative APA+ADT with RP in high-risk disease, needing mature survival and post-salvage data first. https://t.co/rmhKREVtW2

- AEs by CTCAE 5.0
Secondary:
- Best objective response by investigator per RECIST v1.1
Escalation
First-in-human starting dose (0.2 mg/kg Q3W) -> Accelerated dose titration (1 patient per cohort) -> Grade ≥2 related AE -> Standard "3 + 3" dose escalation -> Recommended phase 2 dose
Expansion
- CLDN6-positive platinum-resistant ovarian cancer expansion
- CLDN6-positive refractory NSCLC expansion
- Other CLDN6-positive refractory cancers expansion (including GCT) [highlighted]
- CLDN6-low/negative expansion
- CLDN6-low/positive ovarian cancer Ixo-V + combinations (including bevacizumab)
- CLDN6-positive NSCLC Ixo-V + pembrolizumab

CLDN6 as a Novel Therapeutic Target in GCT
- CLDN6 is a cell surface protein and a member of the claudin family of tight junction molecules1
- CLDN6 is highly expressed in multiple human cancers, including GCT, with little or no expression in healthy adult tissues2-4
- GCT are the most common solid malignancy in adolescent and young adult men and are typically diagnosed in the third and fourth decades of life5-7
- Although most patients with newly-diagnosed GCT are successfully treated with platinum-based chemotherapy, 20-30% relapse5,8,9
- Long-term survival is achieved in <10% of patients who progress post-HDCT/ASCT5,10
- Chemotherapy regimens produce ORRs of ~6-51%9
- Clinically effective salvage therapies are limited5,9

Elegant talk by @MattGalsky looking at molecular drivers and subtypes in relation to treatment benefit in #NIAGARA
#ESMO26 #Day2 @myESMO @OncoAlert https://t.co/nlzwm0f57T
[Slide 1]
NIAGARA: Background
- Muscle-invasive bladder cancer (MIBC) is molecularly heterogeneous, with recurrent alterations in cell-cycle regulation, receptor tyrosine kinase signalling, chromatin remodelling, and DNA damage response (DDR) pathways, alongside high genomic instability. In multiple studies, DDR alterations have been associated with improved response to cisplatin-based neoadjuvant chemotherapy (NAC)1-3
- Transcriptomic-based molecular subtypes further shape prognosis and treatment response by reflecting differences in differentiation state, stromal and immune contexture, and underlying biology4
- NIAGARA is a Phase 3, open-label, randomised trial assessing perioperative durvalumab plus NAC and radical cystectomy (RC) vs NAC and RC alone in patients with MIBC5
- Results from the interim analyses demonstrated that the addition of perioperative durvalumab to NAC resulted in statistically significant improvements in event-free survival (hazard ratio [HR] 0.68) and overall survival (HR 0.75), and a 10% improvement in pathological complete response rate vs NAC5
Here, we report exploratory analyses of MIBC molecular drivers and subtypes in relation to treatment benefit from NIAGARA

[Slide 2]
NIAGARA: Conclusions
- Baseline WES and RNA-seq captured the landscape of key mutational drivers and transcriptome-based subtypes, characteristic of MIBC
- Consistent with cisplatin sensitivity, DDR-related gene alterations (eg, ERCC2) were significantly associated with a higher pCR rate across arms
- Exploratory integrated baseline genomics and transcriptomics from NIAGARA suggest a broad benefit for perioperative durvalumab plus NAC in patients with MIBC
- Shared biology associated with sensitivity to immunotherapy was observed across molecular subtypes of MIBC and was enriched in the basal squamous and luminal infiltrated subtypes, which appeared to derive the most benefit with the addition of perioperative durvalumab to NAC
Exploratory analyses show the addition of perioperative durvalumab to NAC consistently improves EFS across a diverse molecular landscape

ABSTRACT #1900 / FPN ESMO CONGRESS 2026 • TRIAL IN PROGRESS • NCT07484022

Background
Enfortumab vedotin (EV) plus pembrolizumab is a first-line standard for locally advanced or metastatic urothelial cancer.
Systemic release of monomethyl auristatin E (MMAE) from EV contributes to off-target toxicity. Peripheral neuropathy is a key treatment-limiting toxicity of EV, reported in 67%(a) of patients in EV-302, leading to dose interruption (22%), reduction (13%), or discontinuation (15%); symptoms may persist after treatment and limit the duration and intensity of an otherwise effective regimen.
Therapeutic Concept
GB-4362 is designed to selectively bind and neutralize circulating free MMAE without binding intact EV, with the goal of reducing neuropathy and improving the therapeutic window.
Reducing treatment-related toxicities may help patients remain on EV plus pembrolizumab longer and support broader use across community and other care settings.
Phase 1 data may also inform development of GB-4362 with other MMAE-based antibody-drug conjugates, potentially extending the approach to additional cancer types.
GB-4362 has received Fast Track designation from the U.S. FDA for the prevention and/or reduction of EV-induced toxicity in patients with urothelial cancer.
Preclinical Data
In vitro, GB-4362 blocked MMAE, and not ADC cytotoxicity [curve: %viability vs Concentration mAb (nM); GB-4362 + MMAE; GB-4362 + ADC]
In mouse, EV's efficacy was preserved up to 80% MMAE reduction with GB-4362 [Tumor Volume (mm3) vs Time (day); GB-4362 administrations; Vehicle (Negative control); MMAE reduction ≥ ~85% (Postive control); No efficacy impact MMAE reduction ≤ ~80%]
In monkeys, single dose GB-4362 resulted in dose-dependent reduction in free MMAE which was associated with neutropenia improvement
Treatment | Grade 4 Neutropenia (%) | Free MMAE % (AUC0-2wk)
4mg/kg EV | 100% | 100%
4mg/kg EV + 0.5mg/kg GB-4362 | 100% | 74%
4mg/kg EV + 2mg/kg GB-4362 | 50% | 52%
4mg/kg EV + 4mg/kg GB-4362 | 33% | 32%
Grade 4 neutropenia is defined as ANC < 0.5 × 10^3 cells/µL. EV = enfortumab vedotin
Dose-escalation study design

Slide: Antonarakis: Conclusions — clonal hematopoiesis vs tumor HRR alterations in liquid biopsy, PARPi
Important data from #ESMO2026 in #mCRPC:
🧬 56% of HRR alterations detected by liquid biopsy were predicted to originate from clonal hematopoiesis (CH).
⚠️ Patients with CH-only HRR alterations did not appear to benefit from PARPi monotherapy.
Distinguishing CH from tumor-derived mutations is critical for treatment selection. #ProstateCancer @EAntonarakis @urotoday @PCF_Science @OncoAlert
[Slide 1]
CONCLUSIONS
• There is a high prevalence of predicted CH among HRR gene mutations in liquid-biopsy samples (56% overall), including in BRCA1 (32%) and PALB2 (24%).
• Patients with predicted CH-only HRR alterations do not appear to benefit from PARPi monotherapy, highlighting the importance of accounting for HRR mutation origin in therapy selection.
• Some CH-predicted mutations are enriched in samples after PARPi exposure, including TP53, NF1, pTERT and CBL.

And now @Maroto5Pablo reporting long term follow-up from phase Ib/II #EV-103 study.
Consistent with prior reports:
EV+P demonstrated sustained responses and survival, with a manageable safety profile.
#ESMO26 #Day2 @myESMO @OncoAlert https://t.co/OwVOGf2vtm
[Slide 2]
Conclusions: EV-103 cohorts DE, A, and K
• This analysis reports the longest follow-up to date from the phase 1b/2 EV-103 study (64.2 mo for the pooled EV+P cohort), demonstrating sustained responses and survival with 1L EV+P in patients with la/mUC who are cisplatin ineligible
• Median OS was 27.7 months in the pooled EV+P cohort and 22.8 months in the EV monotherapy cohort, and an estimated 33% of patients in the pooled EV+P cohort and 23.9% in the EV monotherapy cohort were alive at 5 years
– These data are notable given the historically poor outcomes in advanced UC (eg, 9.6% 5-y relative survival for metastatic bladder cancer, SEER; 8.4% of cisplatin-ineligible patients alive at 4.5-y median follow-up, EORTC 30986)(1,2)
• Consistent with previous reports,(3-5) the safety profile was manageable and most treatment-related AEs of special interest for EV improved or resolved over time and no new safety signals were observed
• These data are consistent with EV-302, reinforcing the long-term benefit-risk profile, sustained survival benefits, and 1L standard-of-care role of EV+P in la/mUC

POTOMAC: Conclusions
• Durvalumab plus BCG (I+M) reduced the risk of high-risk disease recurrence or death by 44% in patients with papillary only tumours compared with BCG (I+M) alone (HR 0.56, 95% CI, 0.37–0.84)1
• In patients with papillary only tumours, the addition of durvalumab to BCG (I+M) therapy led to:
• Fewer early high-risk disease recurrences
• Fewer BCG unresponsive recurrences
• Fewer cystectomies performed, with a favourable trend for cystectomy-free survival
• Similar results were observed in patients with T1 disease
• Safety of durvalumab plus BCG (I+M) in patients with papillary only tumours was consistent with the overall safety population and with the known safety profiles of the individual therapies
• The majority of imAEs were low grade and most resolved or were resolving at the data cutoff; imAEs were consistent with the known safety profile of durvalumab

#ESMO26 A multicenter study (n=671) exploring the clinical and molecular drivers of PSA ≤0.2 ng/mL was presented:
📌65.2% achieved a deep PSA response
📌Median CRPC-free survival: 88 vs 13.3 months
📌Median OS: 83.5 vs 31.5 months
📌Nonresponders showed enrichment of cell-cycle, chromosomal instability, DNA-repair and neuroendocrine programs
📌Deep responders had greater AR activity and enrichment of SPOP mutations
🚨Failure to achieve deep PSA suppression may reflect aggressive tumor biology, not simply inadequate treatment intensity.

1. BACKGROUND
• Germline testing is recommended for all mPC patients irrespective of age, family history or tumour characteristics.
• In other malignancies, early-onset and de novo disease are enriched for PGVs, and younger patients are often priorised for testing.
• Whether early-onset prostate cancer (<55y) truly shows increased PGV frequency has not been established.
2. OBJECTIVES
• Evaluate the prevalence of germline PGVs in mPC according to age.
• Assess whether age, de novo or recurring disease are associated with PGV frequency.
3. STUDY COHORT
1,036 mPC patients
Age groups (years): <55 n=99 (9.6%); 55-65 n=326 (31.5%); 65-75 n=402 (38.8%); >75 n=209 (20.2%)
de novo mPC (56.8%); Recurrent mPC (43.1%)
Targeted sequencing of 11 genes recommended by ASCO for germline testing in PC: BRCA1, BRCA2, EPCAM, HOXB13, MLH1, MSH2, MSH6, PMS2, ATM, CHEK2 AND PALB2
4. METHODS
Germline DNA extraction, library preparation & hybridisation capture → Targeted sequencing (Illumina sequencing; ASCO recommended gene panel) → Variant calling & classification (ACMG criteria) → PGV definition: Pathogenic / Likely pathogenic = PGV carrier
5. RESULTS
5.1 Overall PGV Prevalence: 5.31% (n=55)
Gene | % (n)
BRCA2 | 2.70% (28)
CHEK2 | 0.87% (9)
ATM | 0.77% (8)
PALB2 | 0.29% (3)
BRCA1 | 0.29 (3)
MSH2 | 0.19% (2)
PMS2 | ≤0.1% (1)
MSH6 | ≤0.1% (1)
5.2 PGV prevalence by presentation: p > 0.5 (Fisher's test); de novo 5.43%; Recurrent 5.15%
5.3 PGV prevalence by age group: <55 5.05% (n=5); 55-65 7.67% (n=25); 65-75 5.22% (n=21); >75 1.91% (n=4); Overall: 5.31%
• No significant trend across age groups (Cochran-Armitage p=0.24)
• ≤55 vs >55: 5.05% vs 5.5% (Fisher's test p>0.5)
• ≤75 vs >75: lower prevalence in >75 (Fisher's test p = 0.04)
6. KEY FINDINGS
Overall PGV prevalence 5.31%
BRCA2 most frequent 2.70%
Similar de novo vs recurrent 5.48% vs 5.15% (p > 0.5)
No significant age trend p = 0.24 (Cochran-Armitage)
7. CONCLUSIONS
→Age at diagnosis was not significantly as[sociated with PGV] prevalence in mPC. [partly obscured]
→No enrichment in PGVs was observed [in de] novo cases.
→The reduced prevalence in patients [>75 did not translate] into a significant overall trend. [partly obscured]
→Overall PGV prevalence aligns with [obscured]
Age and timing of metastasis [are not] predictors of PGV carrier status [and] support germline testing acros[s ...] [obscured by presenter]

Phase 1b/2 EV-103 (KEYNOTE-869)a Study Overview
• EV-103 first demonstrated durable clinical benefit with 1L EV+P in cisplatin-ineligible la/mUC, supporting the initial indication in this population1,2
• EV-302 (KEYNOTE-A39)b subsequently confirmed these findings and established EV+P as a standard of care in la/mUC3-5
• This long-term follow-up evaluated clinical benefit durability and long-term safety of EV+P
• With the longest follow-up of EV+P in la/mUC to date, these results may help guide real-world management and optimize patient benefit

Study Treatment
Lenvatinib 20 mg once daily orally Plus Pembrolizumab 200 mg iv. Every 3 weeks (maximum 35 cycles)
Until disease progression, unacceptable adverse events, or patient withdrawal
Endpoints
Primary
- ORR according to RECIST v1.1 (by investigator)
Secondary
- PFS (by investigator)
- OS
- Safety profile
NCT05036434. Data cut-off: 6 Mar, 2026
Hypothesis and sample size determination
- Simon's optimal two-stage design
- Null ORR 10%(P0) vs. target ORR 30% (P1), α=0.05 and 80% power
- Stage 1: 10 patients; ≥2 responses required to proceed to stage 2 (19 additional patients)
- Planned enrollment: 30 (29 evaluable, allowing of 5% drop-out)
- Primary endpoint met if ≥6 of 29 evaluable patients achieve an object response.
[Slide 2]
[ESMO Congress Madrid 2026 logo]
Conclusion
- ACCOMPLISH met its primary endpoint, with a confirmed ORR of 27% (8 of 30 patients; 95% CI 12-46%). Lenvatinib plus pembrolizumab demonstrated meaningful antitumor activity in advanced ACC after mitotane and platinum-based chemotherapy.
- The safety profile was consistent with previous reports of this combination, and no new safety signals were identified.
- These results support lenvatinib plus pembrolizumab as a potential treatment option in this setting.

Slide: Summary: small-cell GU neuroendocrine carcinoma of the bladder (De Santis, ESMO 2026)
Insightful talk on small cell neuroendocrine carcinoma of bladder by #MariaDeSantis.
Platinium remains the backbone. DLL3 is a promising therapeutic target.
#ESMO26 #Day2 @myESMO @OncoAlert https://t.co/gTITpXUHSW
[Slide 1]
Summary
Small-cell GU neuroendocrine carcinoma - focus on the bladder
▪ Early systemic risk
▪ Expert pathology and systemic staging are essential, even in cT1 bladder disease.
▪ Platinum remains the backbone – analogy with small cell lung cancer (SCLC)
▪ Platinum–etoposide produces 40-60% responses, but durability is limited.
▪ Localised bladder disease needs multimodal therapy
▪ Combine platinum-etoposide with radical cystectomy or definitive chemoradiotherapy.
▪ Immunotherapy in analogy with SCLC is promising option, but requires caution
▪ Bladder-specific survival benefit remains unproven. Curative use remains investigational.
▪ DLL3 is a promising therapeutic target
▪ Early activity supports biomarker-directed trials. GU efficacy and survival benefit need confirmation.
Evidence remains limited: multidisciplinary decisions and clinical-trial enrolment are central

INTRODUCTION: Molecular profiling has become an integral component of precision oncology in prostate cancer, particularly in advanced disease, where the identification of actionable alterations may inform the use of targeted therapies and refine prognostic assessment. Genomic alterations involving androgen receptor signaling, tumor suppressor genes, homologous recombination repair, and mismatch repair define biologically relevant subgroups; however, these events do not occur in isolation. Their patterns of co-occurrence may reflect cooperating pathways that contribute to tumor progression, whereas mutual exclusivity may identify distinct molecular lineages, redundant oncogenic mechanisms, or biologically incompatible genomic states. Characterizing these relationships in real-world populations may therefore improve the interpretation of complex molecular reports. The aim of this analysis was to identify patterns of co-occurrence and mutual exclusivity among predefined molecular alteration groups in patients with prostate cancer included in the prospective WAYFIND-R real-world genomic database.
Methods: Data were prospectively collected from the WAYFIND-R database. Patients were stratified into 7 groups according to the predominant molecular profile: G0_SPOP, G1_AR, G2_TumorSuppressorGenes, G3_HRR, G4_MMR, G5_CHIP, and G6_Other.
Results:
97 patients profiled ; 533 of 904 screened genes (59%) harbored a detectable mutation across the cohort; 41% showed no mutation detected in the tested panel.
G2_Tumor Suppressors was the most frequent clinically relevant subgroup (48.4%), followed by G3_HRR (35.0%).
CONCLUSION
TumorSuppressorGenes appear to act as a common molecular denominator, suggesting that tumor suppressor gene alterations may represent a common genomic background upon which additional molecular events accumulate. Robust patterns of mutual exclusivity were not observed across most molecular subgroups, except SPOP ↔ CHIP relationship. The presence of CHIP mutations in nearly 20% of patients represents a clinically relevant finding that should be considered to avoid false-positive interpretation of somatic tumor variants.
We want to thanks all the WAYFIND-R´s patients and their families

🚨⭐🔵 #ESMO26 | New Targets in Prostate Cancer: ADCs & Emerging Biologies
🎤 Presented by Ana Aparicio 🇺🇸 | MD Anderson Cancer Center
@OncoAlert
🔬 ADCs in mCRPC: Is choosing the right target enough, or does the construct matter just as much?
A fascinating overview of the next generation of antibody-drug conjugates in #ProstateCancer.
🧬 1️⃣ WHAT DETERMINES ADC ACTIVITY?
ADC efficacy depends on much more than antigen expression:
🔹 Target density and inter/intratumoral heterogeneity
🔹 Antigen shedding and internalization
🔹 Intracellular trafficking
🔹 Antibody, linker, payload and drug-to-antibody ratio (DAR)
🔹 Bystander effect
🔹 Tumor microenvironment and resistance mechanisms
📌 Target expression is dynamic—not a fixed biological property.
🎯 2️⃣ PHASE III: B7-H3 ADCs MOVE FORWARD
Two major randomized trials are evaluating B7-H3-directed ADCs against docetaxel in mCRPC:
✅ IDeate-Prostate01
NCT06925737 | N=1,440
• Ifinatamab deruxtecan (I-DXd)
• B7-H3-directed ADC
• Topoisomerase I inhibitor payload
• DAR 4
✅ BNT324-03
NCT07365995 | N=736
• BNT324 (DB-1311)
• B7-H3-directed ADC
• Topoisomerase I inhibitor payload
• DAR 6
🔬 These studies will help determine whether ADCs can improve outcomes over taxane chemotherapy.
💥 3️⃣ ABBV-969: A BISPECIFIC ADC TARGETING PSMA + STEAP1
A particularly innovative approach designed to address heterogeneous target expression.
Phase I | N=49 heavily pretreated patients with mCRPC.
📊 At doses ≥3 mg/kg:
✅ Confirmed PSA50 response: 67%
✅ Confirmed PSA90 response: 28%
✅ Confirmed ORR: 45% among 29 RECIST-evaluable patients
⚠️ Grade ≥3 treatment-emergent AEs: 63%, predominantly anemia.
📌 Encouraging antitumor activity, including in patients previously treated with taxanes and radioligand therapy, but still early-phase evidence.
🧬 4️⃣ EMERGING TARGETS: STEAP2 & CD46
🔹 STEAP2: Potentially favorable and relatively homogeneous expression across prostate cancer progression.
🔹 CD46: Broadly expressed membrane protein with internalization properties that may be exploited therapeutically.
Both represent interesting opportunities for ADC development, although expression and biological rationale alone cannot establish clinical efficacy.
🔬 CONCLUSION
The ADC landscape in prostate cancer is expanding beyond single-target approaches.
Bispecific constructs, novel payloads and strategies addressing tumor heterogeneity may help overcome resistance.
⭐ MY POINT OF VIEW | CLINICAL PEARL
The future of ADC therapy in prostate cancer will not be determined by identifying the most highly expressed antigen alone.
What matters is the interaction between:
🎯 The right target
🧬 The right construct
💊 The right payload
👤 The right patient
💡 A highly expressed target does not guarantee an effective ADC—and heterogeneous expression does not necessarily preclude response.
The challenge is to translate molecular targeting into durable survival benefit with an acceptable therapeutic index.
📌 For now, these agents remain investigational. Randomized efficacy, safety and biomarker data will determine their place in clinical practice.

🚨 First-in-class RIPTAC™ in mAPMR
Thrilled to see this beautifully presented by @BGarmezy at #ESMO26.
JNJ-6143 is a first-in-class RIPTAC™ targeting AR × BRD4, designed to induce BRD4 loss of function and prostate cancer cell death. https://t.co/jA1TO8j0OC
[Slide 1]
JNJ-6143: Conclusions
• JNJ-6143 is a first-in-class RIPTAC™ molecule that forms a targeted dual-protein lock between AR (PC-selective tumor antigen) and BRD4 (essential cell survival protein) to trigger cell death
• JNJ-6143 was highly active with an encouraging safety profile in this phase 1 study of patients with heavily pretreated mCRPC
• At the RP2D of 50 mg once daily (oral):
– <60% any grade TRAEs
– 77% confirmed PSA50 rate and 48% confirmed PSA90 rate
– High PSA response rate irrespective of high-risk molecular features
– 69% confirmed ORR
• A phase 2 study (NCT07832292) has been initiated with 50 mg once daily
These early data suggest that JNJ-6143 has the potential to combine high tumor selectivity and robust efficacy with a favorable safety profile and convenient oral administration

🚨⭐🔵 #ESMO26 Novel AR targeted therapies in mCRPC
🎤 Presented by Alice Bernard-Tessier
@OncoAlert
🔬 Androgen receptor (AR) remains a central therapeutic target in mCRPC—but the field is clearly evolving beyond conventional ARPIs.
📌 KEY CONCEPTS
🧬 1. AR alterations are common
AR alterations are enriched in mCRPC and may be found in up to 80% of patients, including:
• AR amplification
• AR mutations
• AR splice variants
• AR rearrangements
These alterations are associated with worse prognosis, although their role as fully validated predictive biomarkers of ARPI resistance remains incomplete.
💊 2. The next generation of AR targeting is expanding
The session reviewed several new strategies beyond standard AR pathway inhibition:
• Next-generation AR inhibitors
• AR degraders
• CYP11A1 inhibition
• RIPTACs, a novel concept exploiting AR presence, rather than classic AR dependence
🧪 3. AR degraders are gaining momentum
Emerging compounds and trials suggest that AR degradation may overcome resistance mechanisms not fully addressed by current ARPIs.
Examples discussed included:
• Luxdegalutamide
• BMS-986460
• Other AR degraders in clinical development
🧬 4. Genotype may increasingly guide drug choice
A major practical message from this talk:
“Genotype picks the drug.”
Different novel strategies may be better suited for different AR alterations:
• AR degraders and CYP11A1 inhibition may be particularly relevant when tumors harbor AR alterations
• AR activating mutations may identify biologically distinct therapeutic vulnerabilities
💥 5. RIPTACs may shift the paradigm
The RIPTAC concept is especially interesting because it moves the field:
➡️ from AR dependence to AR presence
This could potentially expand AR-directed therapy even in tumors where canonical AR addiction is less clear.
Early phase 1 data with JNJ-6143 showed PSA responses across doses and across heterogeneous molecular backgrounds.
📌 TAKE-HOME MESSAGES
1️⃣ AR is still the target.
2️⃣ AR alterations are frequent and drive resistance to ARPIs.
3️⃣ Genotype may increasingly determine therapeutic selection.
4️⃣ RIPTACs introduce a potentially new framework for AR-directed therapy.
⭐ MY POINT OF VIEW | CLINICAL PEARL
This talk reinforces that mCRPC is entering a more biologically segmented era.
The future is not simply “more AR blockade,” but smarter AR targeting, choosing the right mechanism for the right resistance biology.
💡 The real shift is from one-size-fits-all AR inhibition to precision AR-directed therapy.
For daily practice, this means molecular characterization will become progressively more relevant—not only for prognosis, but for selecting the next therapeutic strategy after ARPI resistance emerges.

🚨⭐🔵 #ESMO26 | Emerging Immune-Based Therapies in Prostate Cancer
From Molecular Selection to Next-Generation Immunotherapy in mCRPC
🎤 Presented by Niven Mehra 🇳🇱
@OncoAlert
🔬 Is prostate cancer really an immunologically cold tumor—or have we simply not identified the right patients and therapeutic platforms?
An outstanding overview of the evolving immunotherapy landscape in #ProstateCancer.
🧬 1️⃣ CHECKPOINT INHIBITION: BIOMARKERS MATTER
dMMR/MSI-H (~3% of patients) remains the best-established subgroup for immune checkpoint inhibition in mCRPC.
📊 International multicenter real-world cohort (n=93):
✅ ORR: 46%
✅ PSA50 response: 60%
✅ Median PFS: 7.7 months
✅ Median OS: 27 months
✅ 3-year PFS: 26%
🔬 INSPIRE: nivolumab + ipilimumab
In the dMMR subgroup:
✅ ORR: 75%
✅ PSA50: 86%
✅ Median PFS: 32.7 months
⚠️ Grade ≥3 treatment-related AEs occurred in 48% of the overall INSPIRE population.
📌 CDK12 and BRCA2 alterations alone are not sufficiently validated predictive biomarkers for checkpoint inhibition. TMB-high/MSS disease remains a more uncertain subgroup.
🎯 Clinical implication: Test for dMMR/MSI-H. Missing this biomarker can mean missing a meaningful therapeutic opportunity.
💥 2️⃣ T-CELL ENGAGERS: A NEW FRONTIER
Among emerging immune strategies, T-cell engagers are one of the most clinically advanced approaches.
🔹 Xaluritamig (STEAP1 × CD3)
Demonstrates early antitumor activity in mCRPC, with cytokine release syndrome remaining a major consideration.
🔹 Pasritamig (KLK2 × CD3)
Phase I | N=174
✅ PSA50: 42.4% at the recommended phase II dose (n=33)
✅ Median rPFS: 7.85 months in that cohort
✅ CRS: 8.9%, all grade 1, in the RP2D safety population
🔹 Conditionally activated PSMA engagers
JANX007 and VIR-5500 illustrate how tumor-selective activation and masking technologies may improve the therapeutic window.
🔬 The challenge is no longer simply engaging T cells, but achieving sustained activity while limiting cytokine release, immunogenicity and on-target/off-tumor toxicity.
🧪 3️⃣ CAR-T THERAPY: PROOF OF CONCEPT
Early phase I programs targeting PSCA, PSMA and other prostate-associated antigens demonstrate feasibility.
However, important challenges remain:
• T-cell persistence
• Antigen heterogeneity
• Immunosuppressive tumor microenvironment
• On-target/off-tumor toxicity
• Manufacturing complexity
📌 Promising biology, but not yet an established treatment in prostate cancer.
💉 4️⃣ PERSONALIZED VACCINES & IN-SITU IMMUNOTHERAPY
Personalized neoantigen vaccines aim to generate immune responses against patient-specific tumor mutations.
Manufacturing time, low neoantigen burden and limited immunogenicity remain important barriers.
🔬 SYNC-T SV-102: intratumoral immunotherapy
Early phase I results (n=15):
✅ ORR: 87%
✅ Complete responses: 53%
⚠️ Highly encouraging, but preliminary findings from a very small, selected cohort requiring independent validation.
🦠 5️⃣ ONCOLYTIC VIROTHERAPY
CAN-2409 + radiotherapy represents an important randomized phase III development in localized prostate cancer.
📊 N=745
✅ Disease-free survival HR 0.70
✅ 95% CI 0.52–0.94
✅ p=0.016
An important proof of concept for immune-based therapeutic strategies, although these findings concern localized disease rather than mCRPC.
🧬 6️⃣ PATIENT SELECTION WILL BE EVERYTHING
Future immune strategies may require different selection criteria:
🔹 dMMR/MSI-H → checkpoint inhibitors
🔹 Antigen expression (STEAP1, KLK2, PSMA) → T-cell engagers
🔹 Low disease burden and favorable immune contexture → possible opportunities for vaccines and in-situ immunotherapy
Emerging biomarkers include genomic and transcriptomic profiles, antigen heterogeneity, ctDNA tumor fraction and PSMA-PET tumor volume.
⭐ MY POINT OF VIEW | CLINICAL PEARL
Prostate cancer is not uniformly resistant to immunotherapy. Our challenge is identifying which immune strategy fits each biological context.
Three important lessons:
✅ Molecular testing must be integrated into routine metastatic prostate cancer care.
✅ T-cell engagers may expand immunotherapy beyond the small dMMR/MSI-H population.
✅ CAR-T cells, vaccines and oncolytic approaches are exciting, but clinical adoption must follow robust evidence of meaningful patient benefit.
💡 The next breakthrough in prostate cancer immunotherapy may come not from activating the immune system more aggressively, but from activating it more precisely.
From biomarker selection to engineered immune recognition: precision immunotherapy is beginning to reshape the field.

🚨⭐🔵 #ESMO26 | Optimising Radioligand Therapy in Advanced Prostate Cancer
🎤 Presented by @AzadOncology 🇦🇺
@OncoAlert
🔬 Beyond ¹⁷⁷Lu-PSMA: combinations, alpha emitters and the emerging promise of Auger electrons.
An excellent overview of how radioligand therapy (RLT) is evolving in #mCRPC.
📊 1️⃣ EVOLUTION: RADIOLIGANDS + DUAL IMMUNOTHERAPY
Phase II EVOLUTION (ANZUP2001):
¹⁷⁷Lu-PSMA-617 + nivolumab/ipilimumab vs ¹⁷⁷Lu-PSMA-617 alone.
✅ PSA-PFS at 12 months: 33% vs 17%
✅ rPFS at 12 months: 47% vs 23%
📈 Median rPFS: 12.0 vs 8.5 months
⚠️ However:
• Grade 3–4 AEs: 75% vs 29%
• Treatment-related myocarditis: 7% in the combination arm
• Trial recruitment stopped early.
⭐ An important reminder: biological synergy must translate into meaningful benefit without unacceptable toxicity.
💊 2️⃣ Lu-PSMA COMBINATIONS: ENCOURAGING SIGNALS
📊 PSA50 | Median rPFS | Median OS
🔹 VISION (¹⁷⁷Lu-PSMA-617 + protocol-permitted standard care): 46% | 8.7 mo | 15.3 mo
🔹 PRINCE (+ pembrolizumab, n=37): 76% | 11.2 mo | 20.8 mo
🔹 LuPARP (+ olaparib, n=29): 69% | 12.8 mo | 33.5 mo
🔹 AlphaBet (+ radium-223, n=33): 55% | 10.0 mo | 13.5 mo
🔹 LuCAB (+ cabazitaxel, n=26): 73% | 10.9 mo | 16.5 mo
⚠️ These are cross-trial descriptive comparisons, not evidence that any combination is superior to VISION. Patient selection, prior therapies and trial designs differ.
☢️ 3️⃣ ALPHA EMITTERS: A NEW LEVEL OF PRECISION
Unlike beta particles, alpha particles have shorter tissue penetration and high linear energy transfer, potentially improving tumor-cell killing.
🔬 PAnTHa: ²²⁵Ac-PSMA-Trillium
Phase I dose escalation | N=50
✅ PSA50: 58% overall
✅ PSA50: 83% at 125 kBq/kg
✅ PSA90: 58% at the expansion dose
✅ ORR: 46%
✅ Disease control: 83%
⚠️ Xerostomia: 76%
⚠️ Grade ≥3 treatment-emergent AEs: 38%
✅ No dose-limiting toxicities observed.
These preliminary results support further investigation, not routine clinical adoption.
⚛️ 4️⃣ AUGER ELECTRONS: TARGETING MICROSCOPIC DISEASE
An exciting emerging concept.
Auger electrons deposit energy over extremely short distances, potentially targeting microscopic tumor deposits and individual cells.
🔬 Terbium-161 (¹⁶¹Tb) emits beta particles and Auger/conversion electrons.
Could this improve radioligand effectiveness against micrometastatic disease?
The biological rationale is compelling, but clinical benefit remains to be demonstrated.
⭐ MY POINT OF VIEW | CLINICAL PEARL
The future of radioligand therapy will not be defined by the strongest radiation emitter, but by the right radiation strategy for the right patient.
Three essential questions remain:
🔹 Which combinations truly improve survival?
🔹 Can we intensify antitumor activity without unacceptable toxicity?
🔹 How should PSMA expression, tumor heterogeneity and disease burden guide isotope selection?
💡 Precision radioligand therapy means more than targeting PSMA: it means optimizing the payload, the partner, the timing and the patient.
From beta to alpha and Auger emitters, we are entering an exciting new era in #ProstateCancer.

🚨⭐🔵 #ESMO26 | Emerging immune-based therapies in mCRPC
🎤 Presented by Niven Mehra
@OncoAlert
🔬 Immunotherapy in prostate cancer is finally becoming more nuanced: checkpoint blockade works in selected biologic subsets, while T-cell engagers are opening a new therapeutic frontier.
📌 KEY MESSAGES
🧬 1. Checkpoint inhibition has clear activity in dMMR / MSI-H mCRPC
International real-world data presented for dMMR/MSI-H mCRPC showed:
✅ ORR: 46%
✅ PSA50 response: 60%
✅ Median PFS: 7.7 months
✅ Median OS: 27 months
This is a critical reminder that prostate cancer is not uniformly immunologically “cold”—selected molecular subgroups can derive meaningful and durable benefit from anti–PD-(L)1 therapy.
📌 In contrast, the role of immunotherapy in TMB-high but microsatellite-stable mCRPC remains much less clear.
🧪 2. Beyond checkpoint blockade, four immune strategies are emerging
The talk reviewed a broader immunotherapy landscape in prostate cancer:
• T-cell engagers
• In-situ vaccines
• Oncolytic viruses
• CAR-T cells
Among these, CD3 T-cell engagers appear particularly advanced and clinically relevant.
🎯 3. T-cell engagers are showing encouraging early activity
Two key examples were highlighted:
Xaluritamig (STEAP1 × CD3)
• Novel bispecific T-cell engager targeting STEAP1
• Early data support proof of concept
• CRS occurred in 72%, but grade ≥3 CRS in only 2%, mostly confined to cycle 1 with step-up dosing
Pasritamig (KLK2 × CD3)
• First-in-class KLK2-directed engager
• 174 patients treated
• PSA50 at RP2D: 42.4%
• KLK2 may provide a more prostate-restricted target and potentially widen the therapeutic window
⚙️ 4. Next-generation engager design aims to improve tolerability
A key challenge for T-cell engagers remains cytokine release and off-tumor toxicity.
Strategies under development include:
• Masking / conditional activation
• Costimulation (signal 2)
• Alternative effectors
These innovations may help preserve efficacy while improving safety and outpatient feasibility.
⭐ MY POINT OF VIEW | CLINICAL PEARL
This talk highlights a very important shift:
Immunotherapy in prostate cancer is no longer a yes-or-no question. It is becoming a biomarker- and platform-specific question.
Checkpoint inhibitors are clearly relevant in dMMR/MSI-H disease, while T-cell engagers may expand immune-based treatment well beyond this small subset.
💡 The future of immune therapy in mCRPC will likely depend on matching the right immune strategy to the right tumor biology—and on engineering therapies that are not only active, but deliverable in practice.
For now:
✅ Test for dMMR/MSI-H
✅ Watch the evolution of T-cell engagers
✅ Expect immune therapy in prostate cancer to become increasingly selective, modular and precision-driven

1. Impact of GLP1 Agonists on Cancer Incidence
KEY ISSUE
Growing global obesity burden
13 human malignancies associated with obesity and identified as obesity-associated cancers (OACs).
KEY INSIGHT
GLP-1 receptor agonists are associated with decreased cancer incidence in diabetic and obese patients.
ESMO COMMITMENT
ESMO advocates for increased investment in cancer prevention research to reduce the risk of OACs.

[Slide 2]
3. "Most Favoured Nation (MFN)"
KEY ISSUE
High U.S. drug prices compared with other high-income countries.
MFN pricing policies aim to align U.S. medicine prices with the lowest prices paid in comparable markets.
KEY INSIGHT
MFN pricing may also lead manufacturers to alter global pricing and launch strategies, with potential consequences for patient access to medicines worldwide.
ESMO COMMITMENT
ESMO advocates for fair, sustainable pricing and reimbursement of cancer medicines, promoting value-based access and affordability while safeguarding timely patient access to innovative cancer treatments worldwide.

6. AI for Clinical Decision-Making
KEY ISSUE
AI-driven clinical decision-making in oncology.
Autonomous AI agents are increasingly capable of supporting complex oncology clinical decision-making.
KEY INSIGHT
AI agents can perform oncology decision-making tasks at near expert level in selected scenarios but require rigorous validation, governance, and human oversight is needed.
ESMO COMMITMENT
ESMO promotes safe and responsible AI adoption in cancer care through its Artificial Intelligence and Digital Oncology (AIDO) Committee and ESMO Basic Requirements for AI-Based Biomarkers in Oncology (EBAI), advancing real-world evidence, validation standards, transparency and human oversight.
Development and validation of an autonomous artificial intelligence agent for clinical decision-making in oncology

[Slide 4]
10. Oncology Workforce Crisis
KEY ISSUE
Growing global cancer workforce shortage.
An estimated 100 million healthcare worker shortfall by 2050 threatens our ability to deliver quality care.
KEY INSIGHT
Without urgent investment in training, retention, wellbeing, and multidisciplinary cancer teams, workforce shortages will continue to worsen while cancer incidence rises.
ESMO COMMITMENT
ESMO advocates for policy solutions to the cancer workforce crisis and supports the EU's efforts to reduce burnout by strengthening psychosocial risk prevention.
ESMO Resilience Task Force Reaccommodation's to Manage Psychosocial Risks, Optimise Well-Being and Reduce Burnout in Oncology.

Biomarker data: Conclusions - clonal hematopoiesis (CH) among HRR mutations in liquid biopsy, Emmanuel
Not all HRR mutations on liquid biopsy are tumour-derived in #prostateCancer
At #ESMO26, 56% of patients with detected HRR mutations had predicted CH-only alterations. These patients appeared to derive little benefit from PARPi monotherapy @EAntonarakis @OncoAlert https://t.co/IPUFQCNMzD
[Slide 1]
CONCLUSIONS
• There is a high prevalence of predicted CH among HRR gene mutations in liquid-biopsy samples (56% overall), including in BRCA1 (32%) and PALB2 (24%).
• Patients with predicted CH-only HRR alterations do not appear to benefit from PARPi monotherapy, highlighting the importance of accounting for HRR mutation origin in therapy selection.
• Some CH-predicted mutations are enriched in samples after PARPi exposure, including TP53, NF1, pTERT and CBL.

#ESMO26 Is chronological age telling us the whole story in advanced prostate cancer? an IRONMAN registry analysis of 4,332 patients showed:
📌Mortality followed a J-shaped pattern, with higher risk in the youngest and oldest patients
📌The excess risk in men <55 years attenuated after adjustment, while mortality remained elevated after age 75
📌Older patients received less chemotherapy and more ADT monotherapy
📌In an exploratory cohort (n=20), clonal hematopoiesis and epigenetic aging were associated with numerically worse survival
📌Age-related survival differences extend beyond treatment patterns, comorbidities and frailty.

#ESMO26 Can we reduce the xerostomia burden of ²²⁵Ac-PSMA therapy?
A detailed xerostomia analysis from the phase I PAnTHA trial of ²²⁵Ac-PSMA-Trillium in heavily pretreated mCRPC (N=50) was presented:
📌Xerostomia was limited to grade 1–2, with no treatment discontinuations
📌At doses ≤125 kBq/kg, grade 2 xerostomia occurred in 22%, with improvement in 88% after treatment
📌At 150 kBq/kg, grade 2 xerostomia increased to 62%
📌Salivary gland radiation exposure increased with dose (p<0.0001)
📌Salivary α-amylase did not predict xerostomia severity (p=0.68)

Great discussions at #ESMO2026!
A pleasure to participate as an invited discussant in today’s Rapid Oral session on #BladderCancer.
From NMIBC to metastatic disease: ADCs, immunotherapy, biomarkers and patient-reported outcomes. The therapeutic landscape is changing rapidly!
But presenting new evidence is only part of the story. Putting results into context and critically assessing their clinical value is essential to understand what should change in daily practice.
Great to share the session with Britt Suelmann and @ProfSyedHussain.
Thank you @myESMO for the invitation and to all the investigators for their outstanding research! And above all : thank you to our patients for their trust.!

Biomarker data: PROMPT (Niven Mehra): Replace, or complement? Tissue NGS vs plasma ctDNA by pathway
Can liquid biopsy replace tumour tissue in mCRPC?
PROMPT study at #ESMO26: ctDNA detected 82% of HRR-altered cases, adding 7% yield to tissue testing.
But PI3K/AKT alterations, particularly PTEN biallelic losses, were frequently missed @MehraNiven @OncoAlert https://t.co/BbaYEskD5C

Plasma alone identifies 50 of 61 altered patients (82%); as an adjunct it adds 4 patients tissue missed (+7%).
Plasma-first is defensible for PARP-inhibitor eligibility.

CONCLUSIONS
SL-28 represents a novel class of cell therapy, demonstrating antitumor activity across multiple biologically distinct cancer types
CR: 33%; PR: 33%; SD: 33%
SL-28 (TELLS) cells are not genetically modified. Their antitumor activity is enhanced through a novel TezR-mediated activation approach, representing the first therapeutic application of this Novel Receptor System
SL-28 is an off-the-shelf, allogeneic cell therapy that does not require HLA matching or immunosuppressive conditioning. Clinical experience to date suggests a favorable safety profile, with no observed GvHD, ICANS, or CRS

1) Biomarker data: Baseline ctDNA Burden Was Prognostic of rPFS in Both Arms · 2) Biomarker data: TALAPRO-3 ctDNA: Conversion ctDNA+ to ctDNA- at Week 5 associated with longer rPFS · 3) Biomarker data: TALAPRO-3 ctDNA tumor fraction analysis - Conclusions
ctDNA tumor fraction in TALAPRO-3 from @AzadOncology at #ESMO26 🧬 In HRR-deficient mCSPC, baseline ctDNA+ (TF ≥1%) was prognostic for rPFS in both arms. Week 5 matters too: 82% of ctDNA+ patients cleared on TALA + ENZA vs 68% on PBO + ENZA, and clearance tracked with longer rPFS (HR 0.36 vs persistent ctDNA+). Early on-treatment ctDNA could become a real tool for risk stratification and monitoring. Next up is whether it adds value beyond PSA. #MRD #ctDNA #ProstateCancer

Conclusions
• In TALAPRO-3, baseline and on-treatment Week 5 ctDNA tumor fraction showed potential prognostic utility for rPFS in mCSPC
• Conversion of ctDNA tumor fraction from positive at baseline to negative at Week 5, which was higher with TALA + ENZA compared with PBO + ENZA, correlated with improved rPFS
• Further investigation will look at whether ctDNA provides independent prognostic value beyond established markers (e.g., PSA at 6 months) through multivariate analysis
ctDNA tumor fraction has potential as a prognostic biomarker and may improve risk stratification and therapeutic monitoring in patients with mCSPC

TCRs clearly work for cancer-testis antigens in select patients and interesting data on TILs to be presented at #ESMO2026 on monday. However, patient selection still restricts who is eligible - target expression, HLA subtype…and geography! Afami-cell only approved by FDA, no other agent.

A decade of lessons
2013 — Lete-cel (NYESO-1) TCR in synovial sarcoma: ORR 20-50%; DOR 15-30 weeks
• Higher LDR impacts efficacy (Flu 120mg/m2 + Cy 2700mg/m2)
• Bridging therapy is essential option
• Correlates of response: expansion, persistence, IL15 levels, depletion of lymphocytes
• Correlates of resistance: loss of HLA expression & Ag presenting machinery
2016 — Lete-cel (NYESO-1) TCR in myxoid round cell liposarcoma: ORR 20-40%; DOR 5-7m
• Correlates of response: Expansion, persistence, IL15 levels, depletion of lymphocytes
• Tocilizumab doesn't appear to impact efficacy
2019 — Afami-cel (MAGE-A4 TCR) in synovial sarcoma + MRCLS: ORR 39% (SS), 25% (MRCLS); DOR 12m (SS), 4m (MRCLS)
• Clinical correlates: Lower disease burden, higher MAGEA4 expression, lack of bridging therapy
• Higher cell dose may impact efficacy
• Integrating cells early is likely better
FDA approved in 2024
2020 — Lete-cel (NYESO-1) TCR in synovial sarcoma + MRCLS: ORR 43%; DOR 12.2m
• Primary endpoint met

Conclusions
Afamicel and letecel have shown promise in synovial sarcoma and myxoid round cell liposarcoma
• There is an on-going need to identify biomarkers of response/resistance
• Consideration of synergistic combinations may optimize efficacy (mRNA vaccines)
Leveraging cancer testis antigens as promising therapeutic targets through alternate therapeutic approaches, ie bispecific antibodies will continue to expand the field via off the shelf-options
Exploring alternate adoptive cell approaches, ie TIL, CAR-T as well as new targets, ie fusions will contribute to novel and exciting therapeutic options in the future and expand beyond the HLA restriction

1) Slide: PROMPT (Niven Mehra): Concordance is high for HRR - PI3K/AKT biallelic loss is the outlier · 2) Kaplan-Meier survival data: PROMPT (Niven Mehra): Only plasma-detected PTEN loss appears prognostic · 3) Slide: Conclusions and take-home message - plasma vs tissue genotyping in prostate cancer
Can plasma replace tissue for genotyping in mCRPC? Niven Mehra presented PROMPT at #ESMO26 🧬 In 301 matched tissue/plasma pairs, plasma alone found 82% of BRCA/HRR-altered patients and added 4 that tissue missed, so plasma-first with reflex to tissue at low tumor fraction is defensible for PARPi eligibility. PI3K/AKT is different: only 38% were caught, mostly from missed PTEN loss. But PTEN loss seen in plasma was prognostic (HR 2.11 adjusted for ctDNA fraction), while tissue-only loss was not. Report a low-TF plasma result as not informative, not negative. #ctDNA #LiquidBiopsy #ProstateCancer
[Slide 1]
Concordance is high for HRR — PI3K/AKT biallelic loss is the outlier
| SNV / indel | Biallelic loss
BRCA1/2 | PPV 82%; PPA 93% (14/15) · 95% CI 70–99% | PPV 100%; PPA 50% (3/6) · 95% CI 19–81%
HRR (non-BRCA) | PPV 97%; PPA 81% (29/36) · 95% CI 65–90% | n/a; n = 1 — not evaluable
PI3K / AKT | PPV 65%; PPA 57% (13/23) · 95% CI 37–74% | PPV 50%; PPA 14% (8/58) · 95% CI 7–25%
Accuracy fails predominantly for detection of copy-number loss in PI3K/AKT — PTEN-dominated
Tissue as comparator, n = 301. PPA = positive percent agreement (plasma-positive among tissue-positive), Wilson 95% CI; PPV = positive predictive value (tissue-positive among plasma-positive). Tissue is a comparator.
Updated after re-review of 10 PTEN homozygous-deletion calls since abstract submission; patients carrying both a BRCA and a non-BRCA HRR alteration (n = 3) are assigned to the BRCA row.

58 of 245 patients are tissue-only, and their survival is comparable to wild-type — 29 vs 32 months, HR 1.16 (0.81–1.66), p = 0.43.
When PTEN loss is visible in plasma, median survival is 11–17 months: HR 3.50, and 2.11 (1.38–3.24) after adjusting for ctDNA fraction.

Conclusions and take-home message
1 BRCA1/2 and HRR
Plasma is a credible standalone test for PARP-inhibitor eligibility when tumour fraction is adequate — 82% of all altered patients, and 100% of tissue-positive SNVs above 5% tumour fraction. As an adjunct it adds 7% over tissue alone.
2 PI3K / AKT
Neither compartment is a gold standard. PTEN loss is spatially heterogeneous and discordance runs in both directions — relevant if the capivasertib biomarker moves from IHC to NGS.
3 Reporting standard
A plasma result below the tumour-fraction threshold should be reported as not informative (not as negative).
Matched leukocyte DNA is essential not optional — 10 apparent HRR/PI3K findings were clonal haematopoiesis.
Proposed pathway for BRCA1/2 and HRR: plasma first at APMR -> reflex to tissue if tumour fraction is below threshold

6/The CSS point estimate still leans toward cystectomy, and the interval is wide enough to drive a cystoscope through.
The OS estimate is 94% weighted on a single NCDB study. Every included study carried serious risk of confounding on ROBINS-I.
Recurrence after bladder sparing ran 33–75%.
LVI was more common in the RC groups, which tells you who got sent to surgery and that a cystectomy specimen finds what a TURBT misses.

INTRODUCTION
Partial nephrectomy, performed as robotic-assisted partial nephrectomy (RAPN), is the standard treatment for localized renal cell carcinoma (RCC), providing excellent outcomes while preserving renal function (1).
The phase II FASTRACK II trial demonstrated promising local control and acceptable toxicity with stereotactic ablative radiotherapy (SABR) (2). However, randomized evidence comparing SABR with surgery in operable patients is lacking.
The RAPSTAR trial aims to address this evidence gap by comparing RAPN with SABR, with a primary focus on renal function preservation. Beyond renal function, the trial will also assess oncological outcomes, treatment-related toxicity, quality of life, and cost-effectiveness.
METHODS
RAPSTAR is a multicenter, randomized, open-label phase III trial comparing RAPN and SABR (1:1) in patients with localized RCC eligible for surgery and radiotherapy. A total of 164 patients (82 per arm) will be enrolled over 4 years, with post-treatment follow-up at 6, 12, 18, and 24 months.
The sample size was calculated using the approach described by Borm et al. (3), assuming a clinically relevant between-group difference of 5 mL/min/1.73 m² in eGFR, a standard deviation of 15 mL/min/1.73 m², R² ≥ 0.5, a two-sided α of 0.05, and 80% power. The calculated sample size of 142 evaluable patients was increased to 164 to account for potential attrition.
The primary analysis is planned in the intention-to-treat population, with a supportive per-protocol analysis.
Inclusion criteria:
• Age ≥18 years
• Biopsy-confirmed diagnosis of RCC with no more than one lesion in one kidney (bilateral RCC allowed)
• Stage I disease (tumour ≤7 cm in diameter)
• ECOG performance status ≤2
• Eligible for both surgery and radiotherapy
• Provision of written informed consent
• Multidisciplinary decision justifying the need for active local treatment
N = 164, 1:1 randomisation, stratification by: ✓ tumour size (T1a vs T1b) ✓ randomising centre
SABR: 26 Gy in 1 fraction for tumors <4 cm; 42 Gy in 3 fractions for tumors 4-7 cm

Background
KIM-1 has emerged as a promising biomarker for RCC. Although current evidence from recent phase III trials supports the prognostic value of circulating KIM-1 in mRCC, the biological role of KIM-1 remains poorly understood.
We investigated the prognostic value of plasma KIM-1 in patients with metastatic RCC treated with immune-based therapies and explored its association with peripheral immune cell phenotypes.
Methods
[Schema: Patients with mRCC → Baseline plasma/PBMC (C1D1) → ICI-based therapy (ICI mono/dual or ICI-TKI) → On-treatment plasma/PBMC (C2D1) → Plasma KIM-1, T cell subsets in PBMC → PFS/OS]
Study design: Multicenter retrospective study in Japan
Participants: Patients who initiated ICI-based therapy for mRCC between October 2018 and July 2024
Treatment regimens: ICI mono/dual: Nivolumab / Ipilimumab + Nivolumab; ICI-TKI: ICI + tyrosine kinase inhibitor (TKI) combinations
Measurements: Plasma KIM-1 and T-cell subsets in peripheral blood mononuclear cells (PBMC) were evaluated by ELISA and flow cytometry, respectively. KIM-1 was measured at baseline and on-treatment (mainly at the second ICI dose).
Endpoints: Associations in plasma KIM-1 levels and T-cell subsets in PBMC of baseline and on-treatment samples with clinical outcomes were evaluated. Analyses were performed using available data.

Discussion
✓ A decrease in circulating KIM-1 during ICI-based therapy was significantly associated with longer OS, whereas the association with PFS did not reach significance.
✓ Higher baseline KIM-1 levels correlated with lower proportions of several peripheral T-cell subsets. The strongest unadjusted correlation was observed for CXCR3+CD8+ T cells, suggesting an association between KIM-1 and peripheral immune composition.
✓ Combining KIM-1 dynamics with baseline CXCR3+CD8+ T-cell proportions may help stratify patients by prognosis. This exploratory finding requires validation, as formal interaction tests were not significant and incremental prognostic value was not established.
✓ The retrospective design, small sample size, multiple comparisons, and variation in on-treatment sampling times limit interpretation.
Take Home Message
1. Lower baseline KIM-1 levels are associated with higher frequencies of T-cell subsets implicated in antitumor immunity, particularly CXCR3+CD8+ T cells.
2. Combining KIM-1 dynamics with baseline CXCR3+CD8+ T cell status may improve prognostic stratification, warranting further validation.

BACKGROUND
In mPC, genomic alterations (GenAlt) may act as predictive biomarkers for treatment selection. HRR gene alterations identify candidates for PARP inhibitors (PARPi); activation of the PI3K/AKT pathway may support AKT inhibitors (capivasertib). Two among TP53, RB1, PTEN alterations are associated with aggressive variant PC (AVPC) and the greatest benefit from chemotherapy. SPOP mutations may predict sensitivity to androgen receptor-targeting agents, whereas the role of TMPRSS2-ERG remains controversial.
Aim: to challenge the single-driver paradigm in mPC by defining co-occurring molecular profiles to guide treatment strategies in the precision-medicine era.
METHODS
342 mPC pts enrolled in the FPG500 program (NCT06020625)
127 (37.1%) excluded: insufficient / damaged biopsy
215 pts with evaluable CGP (TSO500 HT assay)
Pts were stratified into potentially therapeutic profiles:
PARPi – ≥1 HRR gene alteration
AVPC – ≥2 alterations among PTEN, TP53, RB1
AKT-inhibitor – PTEN and/or PIK3CA alterations
Hormone-sensitive – SPOP
TMPRSS2-ERG – TMPRSS2-ERG fusion
RESULTS – TARGETABLE PROFILES
72% of evaluable pts (n=215) harbored a potentially targetable profile
Prevalence of each profile (% of evaluable pts): TMPRSS2-ERG 26%; AKT-inhibitor 22.8%; PARPi 20%; SPOP 11.6%; AVPC 6%
TMPRSS2-ERG was the most frequent profile, followed by the AKT-inhibitor and PARPi profiles. AVPC was identified in 6% (n=13) of pts.
SPOP (11.6%) showed strict mutual exclusivity with TMPRSS2-ERG – two distinct, non-overlapping molecular groups.
RESULTS – CO-OCCURRENCE
Overlap of the AVPC profile (n=13) with other profiles: AKT-inhibitor 92%; TMPRSS2-ERG 54%
92% of AVPC pts also qualified for the AKT-inhibitor profile and 54% overlapped with the TMPRSS2-ERG profile.
33% overall co-occurrence among the other groups, mainly TP53 with PTEN or TMPRSS2
CONCLUSIONS
• Comprehensive genomic profiling identified clinically targetable alterations in the majority of mPC pts (72%).
• The high rate of genomic co-occurrence challenges the single-driver paradigm.
• Findings support the potential role of routine molecular profiling to optimize treatment selection in mPC.

Safety data: CATALINA-1 TEAEs and TRAEs Experienced by >=20% of Patients (Ixo-V, GCT)
First-in-class CLDN6 ADC ixotatug vedotin (Ixo-V) in heavily pretreated relapsed germ cell tumors, presented by Darren Feldman at #ESMO26 🎯 CLDN6 is almost universally expressed in GCT and barely present in healthy adult tissue. In 11 patients from the phase 1 CATALINA-1 study, ORR was 45.5%, DCR 72.7% and mPFS 5.8 months. 3 of 6 responders came after HDCT/ASCT, and one patient with testicular GCT is still responding at 47.4 months. Safety was manageable, with mostly low-grade AEs, reversible G4 neutropenia and no febrile neutropenia. A real option could be emerging for the 20–30% who relapse. #GermCellTumor #TesticularCancer #GUOnc

INTRODUCTION
- Sequencing androgen receptor-pathway inhibitors (ARPI) have limited activity in mCRPC.
- Bipolar androgen therapy (BAT), which cycles serum testosterone between supraphysiological and castrate levels, can resensitize prostate cancer to androgen receptor pathway inhibitors (ARPIs) in patients who previously progressed on them.
- After a course of BAT, enzalutamide rechallenge has yielded meaningful PSA and radiographic responses, with PSA50 rates above 50%. The mechanism is incompletely understood but plausibly reflects BAT's demonstrated ability to downregulate AR and reverse AR-V7 expression in circulating tumor cells.
- To report exploratory genomic biomarker analyses to identify predictors of response.
METHODS
[Figure 1 schema - small text largely illegible: Phase 2, single-arm, multicenter (9 institutions), open-label trial - N = 51 treated patients; Testosterone cypionate (BAT) / Darolutamide / Washout; Endpoints]
- Study Design: phase II, single-arm trial in mCRPC pts after progression to abiraterone (Figure 1).
- Population & Settings: Pts received testosterone cypionate 400 mg IM (day 1) followed by darolutamide 1200 mg/day (days 29-56) in 63-day cycles.
- Data Collection: ctDNA was collected at baseline and end of treatment and evaluated for evaluation by next-generation sequencing (NGS) of AR alterations, including amplification, and mutations as potential biomarkers of rPFS and OS.
- Study Registration: NCT04558866 (ClinicalTrials.gov).
RESULTS
rPFS by AR Amplification Status
- AR amplification was significantly associated with inferior rPFS (median 8.3 vs. 2.9 months; HR 0.39; p = 0.0284), compared to non-amplified status (Figure 2).

CONCLUSION
- Alternating bipolar androgen therapy and darolutamide (ExBAT) showed durable rPFS and a manageable safety profile, in men with mCRPC who progressed on abiraterone.
- Baseline AR amplification emerged as a potential biomarker of resistance to this strategy, identifying a subgroup with markedly worse rPFS and OS and warranting prospective validation as a tool for treatment selection. These findings support further evaluation of BAT-based ARPI sequencing, potentially guided by AR status, as an alternative to conventional therapy in this setting.

INTRODUCTION
❑ The differences between de novo and metachronous mPC are incompletely characterized.
❑ This study compared demographic, clinical, molecular, and immunologic features between de novo and metachronous mPC.
METHODS
The Tempus Lens Platform was used to query the multimodal de-identified database to establish and subsequently analyze a cohort of patients diagnosed with mPC who underwent genomic profiling with xT (DNA) and xR (RNA) (n = 6,306).
Patients were classified as de novo (Stage IV at diagnosis) or metachronous (Stage I–III at diagnosis with progression to Stage IV >180 days later).
De Novo n = 6,171 Metachronous n = 135
❑ Immune cell proportions were estimated from RNA using quanTIseq.
❑ Differential gene expression analyses were conducted using Wilcoxon rank-sum tests with Benjamini-Hochberg correction.
❑ Gene set enrichment analysis was conducted using the Hallmark libraries.
❑ Groups were compared using Wilcoxon rank-sum tests or chi-squared tests as appropriate.
RESULTS
Figure 1. Treatment with prostatectomy or radiation was more common in patients with metachronous disease (prostatectomy: 57% vs 5.2%, radiotherapy: 92% vs 22%, p<0.001).
Figure 2. Treatment with upfront chemotherapy with ADT +/- ARPI was more common in de-novo metastatic pts (15.7% vs 8.1%, p=0.037).
Figure 3. Metachronous pts were enriched for APLNR (13% vs 4.7%, p<0.001) and ZMYM3 somatic alterations (11% vs 4.8%, p<0.001), while most canonical prostate cancer drivers (e.g., TP53, PTEN, ERG) had a similar frequency between groups.

Figure 5. Inflammatory signaling (TNFα/NF-κB) and KRAS-related pathways were enriched in metachronous pts.
SUMMARY
❑ Metachronous mPC is a distinct entity characterized by lower PSA at diagnosis, greater prior local therapy exposure, unique genomic alterations, and a more immunologically suppressed tumor microenvironment compared to de novo disease.
❑ Future work should investigate therapeutic vulnerabilities and differences in survival associated with metachronous vs. de novo disease.

INTRODUCTION
❑ Early-onset prostate cancer (EO-PCa) is increasingly recognized as biologically distinct, but its clinical behavior, molecular features, and outcomes relative to average-onset (AO-PCa) disease remain incompletely characterized.
SUMMARY
• EO-PCa exhibits distinct clinical and molecular characteristics compared to AO-PCa.
• OS appears to be driven by a combination of age and tumor biology.
METHODS
The Tempus Lens platform was used to query the de-identified, multimodal database for patients diagnosed with metastatic prostate cancer (N= 6,967) tested with Tempus xT (DNA-seq) and xR (RNA-seq).
Eligible de novo metastatic patients had a sample collected within 60 days of diagnosis and were stratified by onset age (EO-PCa ≤55 years; AO-PCa >55 years).
❑ Clinicogenomic characteristics were compared using Wilcoxon rank-sum tests or chi-squared tests as appropriate.
❑ Real-world overall survival (rwOS) was defined as the time from sample collection to death or loss to follow up.
❑ Median rwOS (mOS) was estimated using Kaplan-Meier (KM) curves and compared using log-rank tests. Hazard ratios (HR) were estimated using Cox proportional hazards models. Risk set adjustment was used to account for immortal time bias.
RESULTS
Figure 1. Frequency of primary radiotherapy or prostatectomy treatment in EO-PCa vs. AO-PCa. Patients with EO-PCa were more likely to undergo primary treatment (radiotherapy: 37.2% vs 26.4%; prostatectomy: 18.7% vs 10.4%, p<0.001).
Figure 2. Selected molecular differences between EO-PCa and AO-PCa. EO-PCa was enriched for germline BRCA2 variants (4.8% vs 2.6%, p=0.019), TMPRSS2 fusions (39.7% vs 34.7%, p=0.015), and ERG fusions (41.1% vs 36.6%, p=0.031). Somatic FOXA1 (15.4% vs 9.4%, p<0.001) and SPOP mutations (11.1% vs. 8.2%, p=0.033) were more common in AO-PCa.
Figure 3. Median real-world OS for EO-PCa vs. AO-PCa. EO-PCa was associated with longer mOS in the overall cohort [42 vs 32 months, HR = 1.51 (95% CI 1.26-1.81), p<0.001] and in SPOP-alt and TP53-alt sub-cohorts.
[Fig 3 bars, EO/AO months: Overall 42.0/32.0; SPOP alt 67.1/52.0; TP53 alt 33.8/25.9]
Figure 4. Association of SPOP and TP53 alterations with real-world OS in AO-PCa and EO-PCa. SPOP alterations were prognostic for favorable mOS compared to wild-type (AO-PCa: 52 months vs 30.7 months, p<0.001; EO-PCa: 67.1 months vs 41.7 months, p= 0.41). TP53 alterations were prognostic for worse mOS compared to wild-type (AO-PCa: mOS 25.9 months vs 37.9 months, p<0.001; EO-PCa: mOS 33.8 vs 55.9 months, p<0.001).

TALAPRO-2 CTC analysis of TALA + ENZA vs PBO + ENZA in mCRPC (n=599)
🔹 Baseline CTC <5 in 81.5%; CTC=0 in 65.3%
🔹 ≥5→<5 CTC conversion at any time: 90% vs 64%
🔹 Baseline CTC=0 associated with longer rPFS in both arms
TALA+ENZA: HR 0.53
PBO+ENZA: HR 0.42
🔹 CTC <5 similarly prognostic: HR 0.41 & 0.35
🔹 Week 9/17 CTC clearance showed favorable rPFS trends, but small n limited interpretation
🔑 Lower baseline CTC burden was strongly prognostic; CTC conversion was numerically more frequent with TALA + ENZA.

Abstract
[Slide 4]
WUTSUP-02: Conclusions
• The perioperative Tislelizumab with neoadjuvant Disitamab Vedotin demonstrates a positive antitumor activity and a manageable safety profile in high risk, non-metastatic UTUC
• Higher HER2 expression may be associated with numerically greater response rates, but this exploratory finding requires further validation

Background
Cabazitaxel may improve LuPSMA efficacy by overcoming heterogeneous PSMA expression and enhancing radiation damage as a radiosensitiser.
Methods
We conducted a single-arm, investigator-initiated phase I/II trial at two centres. Eligible pts had progressive mCRPC, PSMA-PET positive disease (SUVmax ≥15) without discordance on FDG-PET, and prior treatment with docetaxel and an androgen receptor pathway inhibitor. LuPSMA (7.4 GBq) was administered IV 6-weekly (≤6 cycles), concurrently with cabazitaxel IV 3-weekly (≤12 doses), on days 2 and 23 of a 6-week cycle with G-CSF prophylaxis. Four dose levels of cabazitaxel (12.5mg/m2 -20mg/m2) were evaluated using a 3+3 design. The primary objective was to determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D). Key secondary endpoints included safety, ≥50% PSA response rate (PSA50-RR), PSA- and radiographic progression-free survival (PSA-PFS and rPFS), and overall survival (OS).
Results
Between 26 Jul 2022 and 13 Feb 2025, 35 eligible pts were enrolled. Median (IQR) age was 68.0 years (63.0 - 75.0), baseline PSA 50.2 ug/L (IQR 15.1 - 109.8), PSMA SUVmean 8.3 (6.5 - 10.2), PSMA volume 493.3 mL (119.0-874.7), and FDG volume 85.8 mL (30.0 - 246.9). 25 pts (71%) had de novo metastatic disease; 10 (29%) had M1c disease at baseline. No dose-limiting toxicities were observed. The MTD and RP2D was 20mg/m2 cabazitaxel 3-weekly with 7.4 GBq LuPSMA 6-weekly. 26 (74%) and 22 (63%) pts received all doses of LuPSMA and cabazitaxel, respectively. Clinically significant grade 3 treatment-related adverse events (TRAEs) occurred in 8 (24%) pts: neutropenia, anemia (both n=2), diarrhea, weight loss, urinary tract infection and fatigue (n=1 each). No febrile neutropenia, grade 4 or 5 TRAEs occurred. The efficacy analysis was conducted in pts treated at the MTD (n=26) with a median follow-up of 20.4 months. PSA50-RR was 73% (95% CI 54-86), the median PSA-PFS was 8.5 (95% CI 4.8-12.1), rPFS 10.9 (10.2-13.4) and OS 16.5 (13.4-21.8) months.
Conclusions
Combined LuPSMA and cabazitaxel was safe with encouraging anti-tumour activity in a heavily pre-treated cohort of mCRPC pts with unfavourable baseline characteristics.

Conclusions
• Treatment with talazoparib plus enzalutamide did not result in clinically meaningful differences between arms (≥5-point threshold in overall mean change for deterioration) in HRQoL based on EORTC QLQ-C30 and -PR25 scales, except for appetite loss
• While numerical worsening was noted for several HRQoL parameters in the talazoparib arm compared with the control arm, these differences did not reach the threshold for clinically meaningful difference despite the addition of a third therapy to standard-of-care treatment
• Reduction of HRQoL around Week 17, including fatigue and appetite loss, is consistent with the onset of anemia, which was managed with dose modifications and supportive care
• Time to definitive deterioration in GHS/QoL and urinary symptoms, and time to deterioration in worst pain were comparable between arms
These results can help inform the risk-benefit assessment of talazoparib plus enzalutamide as a potential treatment option for patients with mCSPC harboring HRR gene alterations

BACKGROUND
- Despite major therapeutic advances, precision oncology has had limited impact in the treatment of ccRCC.
- Common genomic drivers are well described, but the biological and clinical significance of rare recurrent somatic alterations remains unclear.
- We hypothesized that a large-scale harmonized multi-cohort analysis could uncover low-frequency yet clinically relevant molecular subsets.
METHODS
[Figure 1. Study overview; Figure 2. Variant calling pipelines for significantly mutated genes (SMGs) and recurrent copy number variants (CNVs); Figure 3. Clinical characteristics of the aggregated cohort - figure text largely illegible]
RESULTS
- Out of 118 SMGs, 72 occurred in fewer than 2% of tumors (long tail of mutations).
- We identified NF2 loss-of-function (LOF) mutations as a recurrent, low-frequency (2%) alteration across cohorts (a).
- NF2 LOF was associated with upregulation of proliferative pathways and downregulation of IFN-y signaling (b).
- Clinically, NF2 LOF was associated with more aggressive disease and worse survival (c), independent of stage, sarcomatoid features, age, and treatment type (d).
[Figure 4. Genomic and survival analyses of NF2 loss-of-function (LOF) tumors - details illegible]
- Other rare LOF alterations included:
MLH1 (0.8%) associated with increased MSI and TMB, a trend towards better outcomes with immunotherapy (IO) and worse survival with VEGF TKI.
B2M (0.6%) associated with downregulation of IFN-y signaling.
STK11 (0.4%) associated with downregulation of immune pathways and worse outcomes with IO.
Comprehensive multi-omic profiling of large harmonized datasets can reveal clinically important subsets missed by smaller studies.
Rare genomic alterations can refine prognostic stratification and therapeutic selection in ccRCC.

Background
- We previously developed a plasma proteomic signature (TKI-POS) by selecting circulating proteins associated with response to TKI therapy in RCC.
- This PRO-TKI score was associated with prolonged OS after treatment with TKI-containing regimens, versus immune-checkpoint inhibitors-only regimens, in an independent validation cohort.
- A bioinformatic analysis of the model proteins was performed to characterize the biological mechanisms underlying the plasma proteins most predictive of TKI benefit.
Methods
[Schema: Pre-treatment Plasma Sample -> Aptamer-based Proteomic Assay -> Computational Analysis -> TKI-positive / TKI-negative]
- Pre-treatment plasma proteomic data from 178 mRCC were generated using SomaScan 7K.
- During the TKI-POS model development, proteins were selected from the 7K panel.
- Protein localization and expression in different tissues were obtained from publicly available datasets.
- Fisher's exact test (FDR<0.1) was used to identify significantly enriched functional groups.

Figure A. Protein localization Venn diagram based on Human Protein Atlas data; B. Protein network of angiogenesis-related proteins; C. Enrichment analysis of the core proteins in the model
Results
- TKI-POS model is comprised of 416 proteins (393 non-redundant proteins). 169 proteins are considered as core predictive proteins, as they had higher weight in the model (i.e., they were selected >=10 times during model development).
- Protein localization analyses support a composite circulating signal derived from tumor, immune and host stromal compartments (Figure A).
- Among the 416 model proteins, 82 were associated with angiogenesis and vascular remodeling.
- Additional proteins associated with TKI response were linked to tumor plasticity (e.g., B-catenin), inflammation (e.g., IL-8 and IL6), endothelial biology (e.g., PLXDC1 and PLXND1), and extracellular matrix remodeling (e.g., THSB2 and THSB4); Figure B.
- Enrichment analysis further demonstrated significant overrepresentation of pathways related to angiogenesis, tumor-promoting inflammation, extracellular matrix remodeling, lipid transport, and poor prognosis in RCC (Figure C).

BACKGROUND
- There is no validated strategy to guide personalized treatment selection following 1st line EV/P failure in mUC
- Liquid biopsy approaches enable real-time functional tumor profiling and may identify emerging actionable targets to inform rational treatment sequencing
- We developed an epigenomic chromatin-based liquid biopsy platform interrogating tumor-derived circulating chromatin using H3K4me2 to capture active enhancer[s] and promoters

[Logos: Dana-Farber Cancer Institute; Harvard Medical School]
Background
- Intrinsic or acquired resistance to LuPSMA is seen in nearly all patients (pts) with mCRPC.
- Biomarkers to select pts for LuPSMA monotherapy, combination strategies or alternative therapies are lacking.
- Serial ctDNA profiling before, during and at progression (PD) on LuPSMA may build on prior publications to elucidate genomic and epigenomic associations with resistance.

- mCRPC pts treated with >=2 cycles of LuPSMA at Dana-Farber Cancer Institute (Jul 2022 - Aug 2024) with research plasma at cycle 1 (C1D1) and at C3D1 and/or PD.
[LuPSMA treatment cycles C1-C6; C1D1 (n=63); C3D1 (n=50); PD (n=41); PredicineCARE: Targeted NGS: SNVs, CNVs, fusions; PredicineSCORE: LP-WGS: CNB score, tumor fraction (TF), ARBS nucleosome profiling]
[Clinical outcome definitions table partly obscured: ...response Best PSA decline >90% 17/72; ...tional response PSA90 or OS >18 mo 24/72; ...c resistance Clinical/radiographic PD <=3 mo or OS <=9 mo 25/72; ...d resistance PD after 3 mo 54/72]
[Stat tiles: 72 treated LuPSMA; 63 with baseline ctDNA NGS; 154 LP-WGS samples (52 pts); 35% intrinsic resistance]
Median age 71 yrs; median PSA 41 ng/mL; visceral metastases 33%. Self-reported Race: 60 White, 6 Black, 4 Hispanic, 1 Asian, 1 N/A
Results: Tumor Fraction & ARBS
Baseline ctDNA tumor fraction is prognostic
[KM: p < 0.0001; table Continuous TF: OS HR 25.6 P 2.6x10^-x; CR-PFS 6.5, 2.3x10^-x; PSA-PFS 6.4, 5.3x10^-x - exponents illegible]
Figure 2. (Left) OS by baseline TF >2% vs <=2%. (Right) Baseline combo TF by response group (Wilcoxon). *Cox HR per unit TF (0-1).
- TF >2% (n=46) vs <=2% (n=17): shorter OS (log-rank p<0.0001).
- Mean TF lower in exceptional responders (0.08 vs 0.33; P=1.3x10^-x) and higher with intrinsic resistance (0.41 vs 0.15; P=1.7x10^-x).
Integrated Analysis of PSA, tumor fraction and AR binding sites during LuPSMA treatment
Figure 3. (A) ARBS abnormality score vs CNV-inferred TF (R=0.81); ... 105/154 samples (68%) CNB-positive; 78/154 (51%) AR-positive by ARBS profiling. In pts 54 and 55, TF and ARBS abnormality fell at C3D1 and rebounded at PD; in pt 54, PSA remained below baseline.
Results: Intrinsic Resistance
Baseline alterations in the 9p21 locus (MTAP, CDKN2A/B), the PI3K/AKT pathway, AR gain, MDM2 gain and BRCA2 were enriched in pts with intrinsic resistance.
[Forest table, Gene | Resistant (n=25) | Non-resist. (n=38) | OR (95% CI) | FDR - e.g. MTAP 11 (44%) | 1 (3%) | 27.5 (3.4->400) | 0.007; CDKN2B 11 (44%) | 2 (5%) | 13.5 (2.5-140) | 0.007; remaining rows small, partially legible]
Figure 4. Baseline gene alterations (SNV/CNV/fusion) associated with intrinsic resistance (all FDR <0.025; n=63).
- PTEN alteration (OR 0.08, FDR 0.034) and MYC gain (OR 0.09, FDR 0.040) were less frequent in exceptional responders.
- Associations are univariable and not adjusted for TF; many CNV associations may reflect higher tumor burden.
Results: Acquired Resistance
Of 41 pts with PD samples, 18 had treatment-emergent or clonally enriched alterations, spanning TP53, DNA repair, PI3K/RAS/MAPK, WNT and AR-axis genes.
Figure 5. Alterations emergent or enriched (VAF increase >10%) at PD vs [...] patient.
- Emergent AR L702H; BRCA2, POLE, MRE11 and P[...] alterations in 5 pts; TP53 in 6 pts.
- 4 clones declined >10% at PD (TP53 x2, RB1, RA[...])
Conclusions
- Baseline ctDNA tumor fraction is strongly prognostic o[...] identifies pts with markedly shorter OS.
- Baseline 9p21 (MTAP/CDKN2A/B) loss, PI3K/AKT alte[...] MDM2 gain and BRCA2 alterations are associated wi[th intrinsic] resistance.
- Acquired resistance is genomically heterogeneous, wi[...] suggests AR signaling is retained at PD in most patie[nts].
- Integrating ctDNA with clinical features may help sele[ct ...] combinations or alternative therapies; validation in la[rger cohorts is] warranted.
- Longitudinal ctDNA tumor fraction dynamics and AR [...] molecular insights beyond PSA alone during prosta[...]
- Plasma cfRNA analysis is ongoing.

BARCODE2: Open-label, single arm phase II study
Part 1: Genetic screening for actionable DRG PGV
- Cohort: mCRPC with prior/ongoing treatment of docetaxel and/or abiraterone/enzalutamide
- Screen using DRG panel (n=115) based on known associations of germline variants with mCRPC* → PGV absent: standard of care off study
- PGV present: monitor until qualifying progression
Part 2: Treatment with 3-weekly carboplatin (AUC5)
- Progression after treatment of docetaxel and abiraterone/enzalutamide ← Direct entrants: mCRPC with eligible treatment history and prior confirmed PGV
- Enter part 2 and start carboplatin
- Follow-up including RECIST, PSA, bone scans and adverse events → Discontinue carboplatin after maximum 10 cycles or disease progression if occurring first

1. BACKGROUND & RATIONALE
High Clinical Burden of BCG Failure:
Intravesical Bacillus Calmette–Guérin (BCG) immunotherapy is the established standard-of-care for high-risk non–muscle invasive bladder cancer (NMIBC). However, up to 50% of patients experience recurrence or progression, frequently requiring radical cystectomy.
Unmet Need for Predictive Biomarkers:
There are currently no validated baseline biomarkers to identify tumors inherently resistant to BCG prior to treatment initiation.
Study Hypothesis & Objective:
We hypothesized that baseline primary NMIBC tumors harbor pre-existing transcriptomic and immunological rewiring that dictates therapeutic failure prior to BCG exposure.
2. METHODOLOGICAL WORKFLOW
Phase 1: Multi-Cohort Harmonization & Quality Control
Transcriptomics datasets (GSE13507, GSE176178, GSE224248) were downloaded from Gene Expression Omnibus. Patient clinical annotations were standardized for recurrence, progression, and BCG response.
Phase 2: Differential Expression & Pathway Scoring (GSVA & GSEA)
Differential gene expression was performed. Gene Set Variation Analysis (GSVA) and GSEA evaluated functional activity across 10,488 GO Biological Processes, KEGG, and HALLMARK pathways.
Phase 3: Immune Microenvironment Deconvolution & Subtyping
xCell algorithms quantified 64 immune and stroma cell types. Unsupervised hierarchical clustering and PCA identified distinct pre-treatment resistance phenotypes among BCG non-responders.
3. SUMMARY TABLE OF ANALYZED COHORTS

🧬 New TALAPRO-3 ctDNA data in HRR-mutated mCSPC at #ESMO26:
• Baseline ctDNA positivity → poorer rPFS in both arms
• ctDNA clearance rates→ higher with TALA+ENZA vs PBO+ENZA
• ctDNA clearance by week 5 → better rPFS in both arms
• Persistently undetectable ctDNA → most favourable outcomes
💡 Take-home: Early ctDNA dynamics show promise for refining prognosis, but are not yet ready to guide routine treatment decisions.

Background
• In the Phase 3 TALAPRO-3 trial, adding TALA (PARPi) to ENZA (ARPI) significantly improved rPFS versus PBO + ENZA in patients with HRR-deficient metastatic castration-sensitive prostate cancer (mCSPC; also known as metastatic APMN/S prostate cancer) (HR=0.48; 95% CI 0.36–0.65; p<0.001)1,2
• Circulating tumor DNA (ctDNA) tumor fraction is an emerging prognostic biomarker with broad potential utility across multiple treatment approaches and tumor types*,3,4
• We assessed the potential prognostic utility of baseline ctDNA tumor fraction and its early on-treatment dynamics, captured as the change at Week 5, in patients from TALAPRO-3
*ctDNA tumor fraction is the proportion of total cell-free DNA in a sample which is tumor derived.4

WUTSUP-02: Background
• UTUC is frequently invasive at diagnosis with high recurrence risks, and its neoadjuvant chemotherapy pCR rate is generally lower than that of bladder cancer; Furthermore, Renal function impairment and cisplatin ineligibility limit treatment options for many UTUC patients, highlighting an urmet need for novel perioperative strategies
• This phase II study aimed to explore the efficacy and safety profile of neoadjuvant Disitamab vedotin (DV, a HER2-targeting ADC) combined with perioperative Tislelizumab (a PD-1 inhibitor) in high risk, non-metastatic UTUC with HER2 expression

1) Slide: Clonal hematopoiesis in HRR genes on liquid biopsy and PARPi outcomes in prostate cancer · 2) Slide: CH vs HRR liquid biopsy PARPi study - Methods and patient flow - Emmanuel S. Antonarakis, ESMO26 · 3) Slide: Variant origin prediction in HRR genes (prostate cancer, F1LCDx) - Emmanuel S. Antonarakis, ESMO26
Interesting data at #ESMO26: 13% of #HRRa on liquid biopsy were predicted to be #clonal #hematopoiesis (CH). Patients with CH-only HRRa had worse outcomes on PARPi vs tumor-derived HRR alterations. Important reminder to account for CH when interpreting ctDNA in mCRPC. @OncoAlert https://t.co/ssI29dzJCn
[Slide 1]
BACKGROUND:
• CH arises from fitness-enhancing hematopoietic mutations, occasionally involving HRR genes, which may lead to false-positive results in liquid biopsies, leading to PARPi treatment in patients who do not harbor tumor-derived HRR mutations.
• In addition, CH alterations may be linked to increased risk of hematological toxicities after therapy, such as myelodysplastic syndrome and acute myeloid leukemia (MDS/AML).
• An algorithm, called "variant origin prediction" (VOP), leveraging cell-free DNA fragmentomics can help infer CH-derived variants without relying on white blood cell sequencing.
• The VOP algorithm achieves 99%, 94%, 94% sensitivity and 100%, 94%, 95% specificity in classifying germline, tumor-somatic and CH-derived short variants, respectively, at the >0.5 threshold.
AIMS:
(1) Describe the prevalence of mutations predicted of CH origin versus germline/tumor origin in HRR genes
(2) Explore the association between CH-predicted vs. germline/tumor HRR genes and outcomes to PARPi
(3) Assess changes in CH prevalence following PARPi exposure

METHODS
• We included patients with prostate cancer and FoundationOne® Liquid CDx (F1LCDx) comprehensive genomic profiling.
• Clinical data were obtained from the US-wide deidentified Flatiron Health-Foundation Medicine clinico-genomic database, from ~280 cancer clinics (~800 sites of care), between 1/2014 - 9/2025.
• Time-to-next treatment (TTNT) and real-world overall survival (rwOS) were compared by Cox models between mCRPC pts receiving PARPi monotherapy with CH-predicted vs. germline/tumor HRR alterations in BRCA1/2, PALB2, RAD51C/D, BARD1, adjusting for clinical covariates.
• CH mutation prevalence in common CH-associated genes was compared pre- vs post- PARPi exposure.

KEYNOTE-905 vs VOLGA | EV has two partners in MIBC!
Both perioperative strategies improve EFS and OS in cisplatin-ineligible MIBC.
🔹 KEYNOTE-905: EV + pembrolizumab, with postoperative EV.
🔹 VOLGA: EV + durvalumab, without postoperative EV.
The key difference? Postoperative EV — 6 cycles vs NONE!
⚠️ Different trials, different designs. Cross-trial comparisons cannot establish superiority.

KEYNOTE-905 / EV-303
Post text
🔬 Great summary by @niklas_kluemper on KEYNOTE-905/EV-303 at #ESMO2026. Let me add the pathology angle, because his key question is ours to answer.
The ad hoc analysis, 255 concurrently randomised, cisplatin-ineligible:
📊 2-yr EFS 41% / 56% / 76% (cystectomy / pembro / EV+P) 🔬 pCR 10% / 25% / 59% 📉 EFS HR 0.71 (0.47–1.07) for pembro, 0.40 (0.25–0.65) for EV+P ⚠️ Grade ≥3 TEAEs 42% / 70% / 69%
Two things I keep coming back to 🧠
1️⃣ The toxicity numbers look reassuring and are not. 70 vs 69% grade ≥3 says EV adds no extra severe events, but a single rate collapses two very different profiles. Neuropathy, skin and metabolic toxicity in a curative-intent setting are not interchangeable with immune-related events, and they persist in survivors. Equal rates, unequal consequences.
2️⃣ 41% of patients on EV+P still have residual disease. We will not find them just with a IHC cutoff. Membranous Nectin-4, read on the membrane only, together with histological subtype and divergent squamous differentiation, is the most informative combination we already have and routinely leave unmeasured.
And a pathology point that follows directly: once pCR carries this much weight, ypT0N0 at cystectomy becomes a high-stakes diagnosis. Thus, Sampling protocols and regression assessment need to be standardised and centrally reviewed, not left to local practice. 🎯
Also worth stating plainly: this is an ad hoc comparison, not a powered head-to-head. Pembro alone did not separate from surgery here (CI crosses 1). Interpret the three-arm ranking accordingly.
Looking forward to Sunday's symposium. 🎤

KEYNOTE-905: what does EV add to pembrolizumab?
ESMO 2026 ad hoc analysis: 255 patients concurrently randomised to all three arms
% of patients - Cystectomy alone / Pembrolizumab / EV + pembrolizumab
2-year EFS: 41 / 56 / 76
pCR (pT0N0): 10 / 25 / 59
Downstaging (<pT2N0): 15 / 34 / 66
0.71 EFS HR pembro vs control (0.47-1.07)
0.40 EFS HR EV-P vs control (0.25-0.65)
15.7 / 28.7 / NR median EFS (months): control / pembro / EV-P
42 / 70 / 69% grade ≥3 TEAEs: control / pembro / EV-P
Pembrolizumab alone is active - but EV more than doubles pCR (59% vs 25%) at a similar grade ≥3 AE rate

#ESMO2026
🚨 Three phase III trials with perioperative chemoimmunotherapy. Different outcomes in MIBC.
NIAGARA: durvalumab + GC → EFS HR 0.68, OS HR 0.75 ✅
KEYNOTE-866: pembrolizumab + GC → EFS HR 0.88, OS HR 1.00
CA017-078: nivolumab + GC → EFS HR 0.94
Interestingly, all three showed numerically higher pCR rates, but only NIAGARA demonstrated statistically significant survival benefits in the reported analyses.
Why? Differences in trial populations, treatment schedules, statistical design—or tumor biology?
These are cross-trial observations, not head-to-head comparisons. We should resist attributing the differences simply to PD-1 versus PD-L1 inhibition.
The key challenge: identifying which MIBC patients truly benefit from adding immunotherapy to chemotherapy.
We urgently need predictive biomarkers and molecularly informed perioperative treatment selection. 🔬

OS HR 0.88 (95% CI 0.64-1.21) not significant^a
Selected trial characteristics
Adjuvant immunotherapy: Yes (durvalumab) | Yes (pembrolizumab) | No
Primary endpoints: EFS and OS (positive) | EFS and OS (not significant) | EFS and pCR (not significant)
Median follow-up: ~34 months | ~41 months | ~55 months
Key takeaway: similar ~9-10 percentage-point pCR gains across trials, but only NIAGARA demonstrated statistically significant EFS and OS benefit.
Cross-trial comparison; not head-to-head. Trial designs, patient populations and follow-up differ.
pCR = pathological complete response; EFS = event-free survival; OS = overall survival; RC = radical cystectomy; GC = gemcitabine/cisplatin.

השנתי של ESMO במדריד מציג גם השנה תמונה מורכבת של התקדמות באונקולוגיה, לצד תוצאות שעשויות לשנות את הטיפול בחלק מהגידולים, מתפרסמים גם מחקרים שליליים המזכירים לנו שלא כל שילוב טיפולי חדש אכן משפר את התוצאות הקליניות.
🏆 אונקולוגיה 🦀 הזוכים 🎉 עד כה...
1. DeLLphi-305 | סרטן ריאה מסוג תאים קטנים, מחלה נרחבת (ES-SCLC)
אחת התוצאות הבולטות היא ממחקר פאזה III שבחן הוספת tarlatamab, נוגדן דו־ספציפי המכוון ל־DLL3, ל־durvalumab כטיפול אחזקה לאחר טיפול ראשוני במחלה שלא התקדמה.
ההבדלים היו משמעותיים:
חציון ההישרדות הכוללת (mOS): 21.1 לעומת 12.7 חודשים (HR 0.42).
חציון ההישרדות ללא התקדמות (mPFS): 7.4 לעומת 1.9 חודשים (HR 0.34).
המשמעות: תוצאה מרשימה, שעשויה לבסס אפשרות טיפולית חדשה באחזקה בקו הראשון בסרטן ריאה מסוג תאים קטנים. לצד עוצמת התועלת, יהיה חשוב להעריך גם את פרופיל הרעילות, ובפרט CRS ורעילות נוירולוגית, ואת היכולת ליישם את הטיפול בשגרה.
2. VOLGA | סרטן שלפוחית השתן החודר לשריר (MIBC)
במחקר פאזה III נבחן טיפול פרי־אופרטיבי ב־enfortumab vedotin (EV) וב־durvalumab בחולים שאינם מתאימים לציספלטין או מסרבים לקבלו.
דווח על שיפור בהישרדות ללא אירוע (EFS; HR 0.55) ובהישרדות הכוללת (OS; HR 0.58), לצד שיעור גבוה יותר של תגובה פתולוגית מלאה (pCR): 45% לעומת 10%.
המשמעות: מדובר בתוצאה חשובה באוכלוסייה עם אפשרויות טיפול מוגבלות. היא מחזקת את מקומם של שילובים המבוססים על ADC ואימונותרפיה במחלה הניתנת לטיפול בכוונה מרפאת. עם זאת, חשוב להבחין בין זרועות הטיפול השונות במחקר, ובפרט בין משטר המבוסס על durvalumab לבין הוספת tremelimumab, שבה לא הודגם עדיין יתרון מובהק בהישרדות הכוללת.
3. STARBOARD | מלנומה מתקדמת עם מוטציית BRAF V600
המחקר בדק שילוב של encorafenib ו־binimetinib עם pembrolizumab לעומת pembrolizumab בלבד בקו הראשון.
התוצאות הצביעו על שיפור משמעותי:
שיעור התגובה האובייקטיבית (ORR): 70% לעומת 32.7%.
חציון PFS: 33 לעומת 3.4 חודשים (HR 0.33).
התועלת ב־PFS ובשיעור התגובה בולטת, אך הרעילות הייתה גבוהה יותר: תופעות לוואי בדרגות 3–4 דווחו ב־70% לעומת 39%. נתוני ההישרדות הכוללת עדיין אינם בשלים.
המשמעות: שילוב מבטיח במיוחד, אך עדיין נותרו שאלות לגבי מיקומו ביחס לאפשרויות אימונותרפיה משולבת אחרות ולגבי מאזן התועלת והרעילות.
4. HERIZON-GEA-01 ו־G-HOPE-001 |
טיפולים חדשים בסרטן הקיבה וה־GEJ
שני מחקרים בולטים בתחום שבו הצורך בטיפולים יעילים עדיין גדול:
HERIZON-GEA-01:
zanidatamab בשילוב כימותרפיה, עם או בלי tislelizumab, בחולים עם מחלה מתקדמת HER2
חיובית.
בזרוע הטיפול המשולש חציון OS הגיע ל־27 חודשים (HR 0.65), וכ־40% מהמטופלים היו בחיים לאחר שלוש שנים.
G-HOPE-001:
ה־ADC arcotatug tavatecan, המכוון ל־CLDN18.2, הראה שיפור בהישרדות הכוללת לעומת טיפול לבחירת הרופא: 10.2 לעומת 6.9 חודשים (HR 0.57). גם ההישרדות ללא התקדמות השתפרה.
המשמעות: שתי התוצאות מחזקות את הפוטנציאל של טיפולים ממוקדים ושל ADCs בסרטן הקיבה וה־GEJ. חשוב לזכור שמדובר באוכלוסיות שונות ובקו טיפול שונה, ולכן אין להסיק מהן על יתרון ישיר של תרופה אחת על פני האחרת.
❌ המאכזב 😞
5. KEYNOTE-866 | סרטן שלפוחית השתן החודר לשריר
במחקר נבחנה הוספת pembrolizumab לכימותרפיה מבוססת cisplatin ו־gemcitabine סביב הניתוח, בחולים המתאימים לציספלטין.
המחקר לא השיג שיפור מובהק ב־EFS (HR 0.88; p=0.1366), ולא הודגם יתרון בהישרדות הכוללת.
המשמעות: תוצאה שלילית עבור המשטר שנבדק. היא מדגישה שלא ניתן להסיק על הצלחת טיפול פרי־אופרטיבי אחד מהצלחת שילוב אחר, גם כאשר שניהם מבוססים על אימונותרפיה.
🔍 החשוד 🤨
6. INTerpath-001 | חיסון mRNA אישי במלנומה
זהו מחקר חיובי מבחינת הישרדות ללא הישנות (RFS) והישרדות
☢️ רדיותרפיה: המחקרים העיקרים 🎯
7. DASL-HiCaP | סרטן ערמונית מקומי בסיכון גבוה מאוד
במחקר פאזה III נבחנה תוספת darolutamide לטיפול הכולל דיכוי אנדרוגני (ADT) והקרנות, בחולים עם סרטן ערמונית מקומי בסיכון גבוה מאוד.
דווח על הפחתה של כ־58% בסיכון לגרורות או למוות. שיעור ההישרדות ללא גרורות (MFS) לאחר ארבע שנים היה 95% לעומת 88%.
המשמעות: תוצאה משמעותית התומכת בהעצמת הטיפול הסיסטמי בחולים המתאימים, על גבי טיפול הכולל הקרנות ו־ADT. חשוב להדגיש שהמחקר בוחן את תוספת darolutamide, ולא את יעילות ההקרנות לבדן.
8. MASTERPLAN | סרטן לבלב מקומי בסיכון גבוה
מחקר פאזה II אקראי בחן הוספת SBRT במינון 40 Gy בחמש פרקציות לכימותרפיה בחולים עם סרטן לבלב מקומי בסיכון גבוה, לרבות מחלה גבולית לנתיחות ומחלה מקומית מתקדמת.
התוצאות היו מעודדות:
חציון OS: 22 לעומת 14 חודשים (HR 0.45).
שיפור גם בהישרדות ללא התקדמות ובשליטה המקומית.
לא זוהתה עלייה ברורה ברעילות החמורה שיוחסה ל־SBRT.
המשמעות: זהו אות חיובי חשוב לתפקידה האפשרי של רדיותרפיה סטריאוטקטית בסרטן לבלב מקומי. עם זאת, המחקר כלל 74 מטופלים בלבד, ונדרש מחקר פאזה III כדי לאשר את התועלת, ובפרט את השפעתה על ההישרדות הכוללת.
9. SARON | סרטן ריאה אוליגומטסטטי
המחקר בחן הוספת רדיותרפיה קונסולידטיבית לטיפול הסיסטמי בחולים עם NSCLC אוליגומטסטטי סינכרוני ללא שינויים גנומיים בני־מטרה (AGA-negative).
נמצא שיפור בהישרדות ללא התקדמות: חציון PFS של 13.9 לעומת 8.9 חודשים (HR 0.64). גם השליטה המקומית השתפרה, עם שיעור כישלון מקומי לאחר 12 חודשים של 13% לעומת 39.5%.
אולם, לא הודגם יתרון בהישרדות הכוללת: חציון OS של 31 לעומת 28 חודשים (HR 0.99).
המשמעות: המחקר מדגים היטב את ההבדל בין שיפור בשליטה המקומית ובהישרדות ללא התקדמות לבין הארכת חיים. התוצאות אינן מבטלות את ערכה של הרדיותרפיה בחולים נבחרים, אך אינן תומכות בקביעה שתוספת טיפול מקומי משפרת OS באוכלוסייה שנבדקה.
לסיכום: לצד ההתלהבות מתוצאות חיוביות, צריך להקפיד להבחין בין מחקר פאזה III למחקר פאזה II, בין ניתוחי ביניים לתוצאות בשלות, ובין שיפור במדדי המחלה לבין הוכחה להארכת חיים.
*הסקירה משקפת את הנתונים שדווחו עד 24 באוקטובר 2026; חלק מהמחקרים עדיין דורשים מעקב נוסף ואימות של התועלת ארוכת הטווח.

Part 1 — Pembrolizumab in Neuroendocrine Prostate Cancer
OS HR 0.33 — A Survival Breakthrough?
01. WHY THIS TRIAL?
• Metastatic neuroendocrine prostate cancer (NEPC).
• Aggressive disease. Poor prognosis.
• De novo or treatment-emergent NEPC.
• Can pembrolizumab improve survival when added to platinum-etoposide?
• Phase Ib/II randomized cohort | N = 70
02. WHAT WAS COMPARED?
PEMBRO + CHEMO | n = 40
• Pembrolizumab 200 mg Q3W
• + Carboplatin AUC 5 D1
• + Etoposide 100 mg/m² D1-3
VERSUS
CHEMO ALONE | n = 30
• Carboplatin + etoposide
• Chemotherapy Q3W × 4-6 cycles.
• Pembrolizumab up to 35 cycles.
• Median follow-up: 15.4 months.

No convincing response advantage.
PD-L1 is NOT yet a validated predictive biomarker in NEPC.
03 — WHAT ABOUT SAFETY?
GRADE 3-5 TREATMENT-RELATED AEs
63% vs 80%
Pembrolizumab + chemo vs chemo alone
Grade 5 TRAEs
0% vs 3%
No unexpected safety signals reported.
Do NOT interpret this as pembrolizumab reducing chemotherapy toxicity.
Small exploratory cohort.
04 — CAN THIS CHANGE PRACTICE?
WHY CAUTION IS NEEDED
• Only 70 patients.
• Exploratory phase Ib/II randomized cohort.
• No formal hypothesis testing.
• PD-L1 analysis was post hoc.
• OS benefit much larger than PFS benefit.
TAKE-HOME
PROMISING OS SIGNAL.
PD-L1 CPS ≥1 MAY ENRICH BENEFIT.
NOT YET A NEW STANDARD OF CARE.

KOL infographic: Perioperative EV in MIBC: vs KEYNOTE-905 cross-trial comparison
Niklas Klümper@niklas_kluemper
KEYNOTE-905 / EV-303VOLGA
Post text
🚨 VOLGA is positive! But how much perioperative EV do we really need in MIBC?
Interesting comparison with KEYNOTE-905 at #ESMO26:
🔹 VOLGA (EV + durvalumab): 2-year EFS 64%, OS 78%, pCR 45%. EFS HR 0.51.
🔹 KEYNOTE-905 (EV + pembrolizumab): 2-year EFS 74.7%, OS 79.7%, pCR 57.1%. EFS HR 0.40.
Numerically lower EFS and pCR in VOLGA. Why?
Different patient populations and tumor characteristics? Different study designs? It seems premature to attribute these differences to pembrolizumab vs durvalumab.
But the most intriguing question is how much benefit does adjuvant EV actually add?
VOLGA achieved a significant OS benefit with just 3 neoadjuvant EV cycles and NO adjuvant EV, whereas KEYNOTE-905 planned 9 EV cycles (3 neoadjuvant + 6 adjuvant)—and fewer than half of patients reportedly completed the full planned EV course.
Could pCR and ctDNA clearance help us safely omit adjuvant EV and reduce cumulative toxicity?
⚠️ Cross-trial comparisons are hypothesis-generating, not evidence of superiority or equivalence. Only prospective trials can establish the incremental benefit of adjuvant EV.
More EV ≠ necessarily better outcomes. Let’s identify who really needs it! 🔬

Safety (grade 3/4 treatment-related AEs) 69% (EV + P) | Completed all 9 adjuvant EV doses < 50% of patients^1
EFS and pCR numerically lower in VOLGA - why?
• Different populations (VOLGA: cisplatin-ineligible/refusing vs KEYNOTE-905: cisplatin-eligible or declining).
• Different immunotherapy backbone (durvalumab vs pembrolizumab) does not appear to fully explain the differences.
• Other factors (patient characteristics, tumor biology, study design) may contribute.
How much does adjuvant EV add?
• Both trials show major survival benefits.
• VOLGA achieves this with only 3 neoadjuvant EV cycles and no adjuvant EV.
• In KEYNOTE-905, <50% received all 9 adjuvant EV doses, leaving the incremental benefit of adjuvant EV uncertain.
Key questions for the future
• Can pCR and ctDNA clearance identify patients who can safely omit adjuvant EV?
• Do we need different strategies for cisplatin-ineligible vs cisplatin-eligible patients?
• Prospective biomarker-guided de-escalation trials are needed.
Both VOLGA and KEYNOTE-905 show substantial survival benefits in cisplatin-ineligible/refusing MIBC.
The optimal amount and timing of perioperative EV - and which patients truly need adjuvant EV - remain open questions.
^1 <50% of patients in KEYNOTE-905 received all 9 planned adjuvant EV doses (NEJM 2026).
Cross-trial descriptive comparison; not a head-to-head analysis. Different patient populations, treatment regimens and follow-up. VOLGA: ESMO 2026 LBA2 (preplanned interimanalysis, median EFS follow-up 22.9 months); KEYNOTE-905: NEJM 2026, doi:10.1056/NEJMoa2511674.

Interesting exploratory ctDNA data from EV-304/KEYNOTE-B15 at #ESMO26 in cisplatin-eligible MIBC.
🔹 ctDNA clearance: 82.1% with EV+P vs 66.7% with gem/cis
🔹 Baseline ctDNA+ patients derived substantial EFS benefit from EV+P (HR 0.54)
🔹 Persistent ctDNA positivity after surgery was associated with poor outcomes regardless of treatment.
ctDNA is a powerful prognostic biomarker, but can it guide treatment selection or bladder preservation? More work is needed.

🚨 VOLGA | ESMO 2026 | LBA2
A major advance in cisplatin-ineligible muscle-invasive bladder cancer!
💚 EV + durvalumab significantly improved survival:
📊 EFS: HR 0.51 | 24-month 64% vs 45%
📊 OS: HR 0.58 | 24-month 78% vs 69%
🔥 The key distinction: EV was given ONLY before surgery — NO postoperative EV!
🤔 Does tremelimumab add meaningful benefit? Is adjuvant durvalumab essential? Can treatment eventually be de-escalated?
Impressive survival benefit. Important questions remain.

- Cisplatin-ineligible or refused cisplatin
- Planned for radical cystectomy
- Randomised phase III (open-label)
[Bladder illustration] Resectable MIBC in cisplatin-ineligible patients
02 STUDY DESIGN
695 patients (1:1:1)
Arm A (n = 233): Neoadjuvant 3 cycles Durvalumab + EV -> Radical cystectomy -> Adjuvant 9 cycles Durvalumab (no EV)
Arm B (n = 233): Neoadjuvant 3 cycles D + EV + 2 cycles T + EV -> Radical cystectomy -> Adjuvant 9 cycles D + 1 cycle T (no EV)
Control (n = 229): Radical cystectomy -> Observation or locally approved adjuvant treatment

03 PRIMARY ENDPOINTS
- Event-free survival (EFS)
- D + EV vs control
- D + T + EV vs control
- Key secondary endpoint Overall survival (OS)
- Safety also assessed
04 KEY RESULTS
DURVALUMAB + EV vs CONTROL
EVENT-FREE SURVIVAL: HR 0.51 (95% CI 0.38-0.67) P < 0.0001; 24-month EFS 64% vs 45%
OVERALL SURVIVAL: HR 0.58 (95% CI 0.40-0.83) P = 0.0027; 24-month OS 78% vs 69%
05 WHAT DOES THIS MEAN?
- First randomised phase III trial showing statistically significant improvement in both EFS and OS with a chemotherapy-free perioperative regimen in cisplatin-ineligible MIBC.
- Large improvement in 24-month survival.
- Provides a new potential standard approach for this population.
06 TAKE-HOME (PART 1)
✓ EV + durvalumab improved EFS and OS versus control.
✓ EFS HR 0.51 | OS HR 0.58.
✓ EV GIVEN ONLY BEFORE SURGERY!
✓ Postoperative treatment = immunotherapy alone.
✓ Survival benefit demonstrated without adjuvant EV.

01 DOES TREMELIMUMAB ADD ANYTHING?
EFFICACY vs CONTROL
EVENT-FREE SURVIVAL
D + EV: HR 0.51 (0.38-0.67) P < 0.0001; 24-mo EFS 64% vs 45%
D + T + EV: HR 0.61 (0.47-0.80) P = 0.0004; 24-mo EFS 60% vs 45%
OVERALL SURVIVAL
D + EV: HR 0.58 (0.40-0.83) P = 0.0027; 24-mo OS 78% vs 69%
D + T + EV: Not significant (follow-up ongoing)
02 PATHOLOGICAL COMPLETE RESPONSE
pCR by local review
D + EV 45% (95% CI 38.6-51.7) | D + T + EV Not reported - | Control 10% (95% CI 6.1-14.2)
Large improvement in pCR with EV + durvalumab vs control.
03 SURGERY GETS DONE
Radical cystectomy completion rate
D + EV 85% | D + T + EV 79% | Control 78%
High and comparable cystectomy completion rates across all arms.
04 ADJUVANT TREATMENT COMPLETION
Completed adjuvant treatment
D + EV 55% | D + T + EV 42%
Many patients could not complete adjuvant immunotherapy.
05 SAFETY
Maximum grade 3/4 treatment-related AEs
D + EV 30% | D + T + EV 42%
Higher toxicity with addition of tremelimumab. No new safety signals.
06 KEY POINTS
- Tremelimumab added to durvalumab + EV improved EFS vs control, but no significant OS benefit at this analysis.
- Greater grade 3/4 toxicity with triple combination (42% vs 30%).
- Surgery was feasible with high completion rates.
- Only 55% and 42% completed adjuvant treatment in the two experimental arms.
07 TAKE-HOME (PART 2)
✓ EV + durvalumab shows meaningful and statistically significant improvement in EFS and OS.
✓ Adding tremelimumab does not clearly improve outcomes and increases toxicity.
✓ Cystectomy completion rates are high and comparable.
✓ Many patients did not complete adjuvant immunotherapy.
✓ EV WAS GIVEN ONLY BEFORE SURGERY. NO ADJUVANT EV IN VOLGA.
CLINICAL INTERPRETATION
- EV + durvalumab is a promising perioperative, chemotherapy-free option for cisplatin-ineligible MIBC.
- No established incremental benefit with tremelimumab.
- Follow-up is ongoing for OS in the triple combination arm.
- Results support a perioperative strategy without postoperative EV.
- The study does not establish whether adjuvant durvalumab can be omitted.

01 WHAT MAKES VOLGA IMPORTANT?
- Phase III trial in cisplatin-ineligible / refusing MIBC.
- Significant improvement in both EFS and OS.
- EFS HR 0.51 | OS HR 0.58.
- 24-month absolute gains: EFS +19% | OS +9%.
- EV given ONLY before surgery!
02 CAN WE OMIT CYSTECTOMY?
NO - NOT BASED ON VOLGA.
- Radical cystectomy was part of the treatment strategy.
- High pCR (45%) is encouraging but does not establish that surgery can be safely omitted.
- Bladder preservation remains investigational.
PATHOLOGICAL COMPLETE RESPONSE
pCR by local review
D + EV 45% (95% CI 38.6-51.7) | Control 10% (95% CI 6.1-14.2)
Large improvement in pCR but does not establish surgery omission.
03 IS ADJUVANT DURVALUMAB ESSENTIAL?
- Only 55% (D + EV) and 42% (D + T + EV) completed adjuvant treatment.
- Survival benefit observed despite incomplete adjuvant therapy.
- The independent contribution of adjuvant durvalumab cannot be determined.
- Can it safely be omitted? Unanswered.
04 WHAT REMAINS UNANSWERED?
- Long-term survival and recurrence outcomes.
- Optimal role of tremelimumab.
- ctDNA-guided treatment selection.
- Whether adjuvant durvalumab can be de-escalated.
TAKE-HOME (PART 3)
✓ VOLGA improved both EFS and OS.
✓ EV was exclusively neoadjuvant.
✓ NO POSTOPERATIVE EV!
✓ Cystectomy remains integral to the tested strategy.
✓ Adjuvant durvalumab cannot yet be safely omitted based on these data.

Great discussions at #ESMO2026!
A pleasure to participate as an invited discussant in today’s Rapid Oral session on #BladderCancer.
From NMIBC to metastatic disease: ADCs, immunotherapy, biomarkers and patient-reported outcomes. The therapeutic landscape is changing rapidly!
But presenting new evidence is only part of the story. Putting results into context and critically assessing their clinical value is essential to understand what should change in daily practice.
Great to share the session with Britt Suelmann and @ProfSyedHussain.
Thank you @myESMO for the invitation and to all the investigators for their outstanding research! And above all : thank you to our patients for their trust.!

Kas invaziv mesane kanserinde perioperatif tedavi
Faz III, çok merkezli, randomize çalışma
Sisplatin alamayan veya sisplatini reddeden kas invaziv mesane kanseri hastaları (n=695)
Amaç
Perioperatif enfortumab vedotin (EV) + durvalumab ± tremelimumab yaklaşımını değerlendirmek.
Çalışma kolları
1 Neoadjuvan EV + durvalumab: Neoadjuvan EV + durvalumab → Radikal sistektomi → Adjuvan durvalumab
2 Neoadjuvan EV + durvalumab + tremelimumab: Neoadjuvan EV + durvalumab + tremelimumab → Radikal sistektomi → Adjuvan durvalumab + tremelimumab
3 Kontrol: Radikal sistektomi → ± uygun adjuvan tedavi
Başlıca sonuçlar (ESMO 2026, LBA2)
2 yıllık EFS: %64 EV + durvalumab grubunda | %45 Kontrol grubunda | HR 0,51
2 yıllık OS: %78 EV + durvalumab grubunda | %69 Kontrol grubunda | HR 0,58
pCR (patolojik tam yanıt): %45 EV + durvalumab grubunda | %10 Kontrol grubunda
Tremelimumab eklenen üçlü kombinasyon (EV + durvalumab + tremelimumab)
• EFS’de anlamlı iyileşme sağladı.
• Ara analizde OS farkı istatistiksel olarak anlamlı değildi.

PHASE 3 DATA · 2026 ESMO CONGRESS
KEYNOTE-B15: ctDNA Clearance and Prognosis in Cisplatin-Eligible MIBC
In an exploratory analysis of the phase 3 KEYNOTE-B15 trial (NCT04700124), perioperative enfortumab vedotin-ejfv (Padcev) plus pembrolizumab (Keytruda) led to higher presurgical ctDNA clearance than neoadjuvant gemcitabine plus cisplatin, and ctDNA status was prognostic for event-free survival in both arms, according to data presented at the 2026 ESMO Congress.
Enfortumab vedotin plus pembrolizumab vs gemcitabine plus cisplatin
Presurgical ctDNA clearance: 82.1% vs 66.7% - 69/84 vs 68/102 patients with detectable ctDNA at baseline
24-mo EFS after ctDNA clearance: 81.1% vs 63.2% - Positive at baseline, negative presurgery (n = 69 vs 68)
pCR if ctDNA negative presurgery: 72.4% vs 43.7% - 131/181 vs 80/183 patients who underwent RC
24-mo EFS if ctDNA+ postsurgery: 10.0% vs 10.0% - HR, 0.63; 95% CI, 0.30-1.35 (n = 10 vs 30)
ctDNA negative postsurgery: 24-mo EFS 89.9% vs 82.2% - HR, 0.48; 95% CI, 0.29-0.81 (n = 199 vs 193)

FAQ
About this page
What is on the ESMO 2026 GU Cancer slides page?
The 260 GU Cancer slide photos, abstract screenshots and data graphics plus 38 KOL-made infographics that oncologists, societies, media and companies posted on X from the ESMO 2026 embargo lift (October 22) through the congress in Madrid (October 23–27), compiled by KOL Pulse. Each card links to the original post and keeps the author's full text. It is one tumor-type page of the ESMO 2026 slide library: https://kolpulse.com/kol-pulse-esmo26-slides
Which GU Cancer trials are covered?
Trials with their own slide groups, by number of slide posts: KEYNOTE-B15 / EV-304 (16), VOLGA (15), DASL-HiCaP (13), ENERGIZE (12), KEYNOTE-866 (10), KEYNOTE-905 / EV-303 (8), TROPHY-U-01 (8), PROTEUS (7), PEACE-1 (7), CAPItello-281 (6), TroFuse-055 (1). Slides that compare several trials sit in a Cross-trial group, and slides not tied to a tracked trial come last. Physician posts come first in every group.
How do I filter by trial or KOL?
Use the trial chips in each section, the Trial menu (which also finds cross-trial slides that name that trial) and the KOL menu or the Built by avatars. Filters combine; counts only offer combinations that have results, and Clear filters or the Escape key resets. Every state has a shareable link, for example #tag=keynoteb15.
What are the OCR text and the source notes?
View OCR Text opens a verbatim transcription of the slide image; survival curves are captured as the printed numbers only, never read off the curve.

Can I use this page with my own AI assistant (NotebookLM, Perplexity, Claude, ChatGPT)?
Yes. Paste the page URL, or a filtered link, into your assistant and ask questions against it. Example prompt: "From the slide transcriptions on this page, list each trial's primary endpoint result with the hazard ratio and data cut exactly as printed on the slide, and the physician who posted it."
