Dr. @bensolomon1 presents IMpower 030: perioperative atezolizumab + chemo in resectable NSCLC at #WCLC26. Unfortunately, EFS did not meet significance. Trends present for EFS and OS but not significant. High rates of surgery in both arms ~90% and placebo arm performed better than expected. Disappointing negative results.
Two negative Phase 3 atezolizumab trials—but two very different messages.
IMpower030 missed its statistical threshold despite a strong efficacy signal. S1914 showed no survival gain and greater toxicity.
In early-stage NSCLC, context matters.

Important findings from the MAVERICK study. Cognitive toxicity is not an abstract endpoint! Memory, concentration, independence, work, driving, child care and simply feeling like yourself significantly impacts #QOL.
But surveillance isn’t burden free for patients & families. It’s regular brain MRIs, living with scan-xiety, time off work, transportation, access to timely imaging AND treatmen

These are fantastic outcomes.

Dr. @JuliaRotow at #WCLC26 with primary results from DESTINY-Lung04: first-line trastuzumab deruxtecan vs platinum + pemetrexed + pembro in advanced HER2 mutant NSCLC. Primary endpoint of PFS favors T-DXd at 14.3 vs 8.3m, HR 0.63 and RR 70% vs 44.5%, DOR 13.7 vs 9.7m, PFS2 22.7 vs 17.3m.
#WCLC26 In DESTINY-Lung04, no OS signal yet. Toxicities led to discontinuation in 16% of both arms. Biggest concern here is the ILD at 20.8% - while most were grade 1/2 and resolved, these are still high rates. This will impact delivery and possibly subsequent therapies... https://t.co/ZUQSd7yaFX

Dr. @bensolomon1 presents IMpower 030: perioperative atezolizumab + chemo in resectable NSCLC at #WCLC26. Unfortunately, EFS did not meet significance. Trends present for EFS and OS but not significant. High rates of surgery in both arms ~90% and placebo arm performed better than expected. Disappointing negative results.
Two negative Phase 3 atezolizumab trials—but two very different messages.
IMpower030 missed its statistical threshold despite a strong efficacy signal. S1914 showed no survival gain and greater toxicity.

MDT-BRIDGE: Treat First. Decide Surgery Later?
A simple but interesting concept in locally advanced NSCLC:
• Start with chemo-immunotherapy rather than locking in the local treatment upfront.
• Then reassess in the MDT.
• If resectable → surgery.
• If not resectable → definitive chemoradiotherapy.
• Continue durvalumab after either pathway.
The idea:
Treat → Reassess → Choose the best curative-
Compelling results from MDT-BRIDGE #WCLC26
Two personal takeaways/ideas
Stop calling full resectability upfront: assess it after neoadjuvant chemo-IO, when the tumour has already shown you what it does.
➕ the value is in the sequence, not just the drug. Prime with IO, let the immune response settle, then irradiate. Personal opinion: it will hold in upfront unresectable disease too (APOLO).

Bayer's HYRNUO first-line expansion rests on SOHO-01, a single-arm study.
Its 75% response rate is evidence of activity. It cannot establish superiority over another treatment without a comparator.
Keep the approval and the comparative claim separate.

😈To play devils advocate, I think FLAURA2 (for sensitizing EGFR mutations), PAPILLION, and REZILIENT3 all point towards the importance of upfront chemotherapy with EGFR inhibition.
💭My thought is that #EGFR lung cancers (esp Exon 20) really do need intensification upfront.
@EGFRResisters @EgfrUk
🤔The myelosuppression in REZILIENT3 is strange. This is the same platinum pemetrexed chemotherapy used in PAPILLION and FLAURA-2, but with way higher adverse event profile.

@DrewMoghanaki Great! So, AS with MRI can be considered as the new SoC ?. Thanks
@_ShankarSiva @DrewMoghanaki Seems to support that the old theory that there were subclinical brain Mets and pci was treating may be false.
@_ShankarSiva @DrewMoghanaki The cumulative incidence of BM was higher with MRI-only. My guess is BMFS was overwhelmed by deaths events rather than brain mets events. One of the reasons why it would be interesting to know the data for limited-stage (less deaths than ES) as a subg
@DrewMoghanaki Treatment of brain metastases only improves OS in 1 scenario - single brain met. PCI goal is prevention of brain metastases and 18% to 5% is 2/3 reduction in likelihood of mets. Mitigate the toxicity using pharmacologic interventions but PCI works.
@PDBrownOnc @DrewMoghanaki @_ShankarSiva I had prior OS at ~0.38 2 yr - here looks closer to .55 (right at top end of 95 CI prior). I think that alter in base outcome is a primary takehome of the trial (along with the likely end of WB/PCI). Only going to move higher faster moving

1. SWOG S1827 MAVERICK
⭐️Perhaps my TOP pick for most important study that will be presented at #WCLC26
🧠PCI reduces brain metastases in SCLC by about 50%, based on older studies that did not mandate MRI surveillance. In the Takahasi et al study, the OS benefit was less clear whe modern MRI surveillance + SRS techniques were used. Add to that the integration of immunotherapy (both PD1 and DLL3 TCE), and the role of PCI will be put to the test.
🧑⚖️MAVERICK will finally adjudicate the decades old question around the role of PCI among patients with #SCLC.

2. HARMONi-2
⭐️HARMONi-6, presented @ASCO earlier this year showed an OS benefit favoring ivonesicimab, a PD1+VEGF bispecific, relative to pembrolizumab in squamous NSCLC
📖Previously published data showed a PFS advantage (11.1 vs 5.8 months; HR 0.51) favoring ivonesicimab. Though even in this study, there were some peculiar findings, like the remarkably poor PFS seen in the pembrolizumab arm for PDL1≥50% (which was nearly half of what was seen in KEYNOTE-24)
🤔But the real question was always OS and dissecting the data here will be key. Like HARMONi-6, I will also want to see these studies replicated on a global scale.

3. B7H3 ADCs in SCLC
⭐️Perhaps the first cytotoxic agent to displace topotecan for relapsed refractory #SCLC.
❗️There has NOT been a single study where topotecan demonstrated an OS benefit when compared to another chemotherapy agent. The only study that showed an OS benefit was the O'Brien 2006 study where it was compared to best supportive care (ie, doing nothing)
‼️The truth is that NO chemotherapy (CAV, ambirubicin, topotecan, irinotecan, lurbinectidin, paclitaxel, temozolomide) has show OS superiority when compared to another cytotoxic in the relapsed / refractory #SCLC.
⚡️The B7H3 ADCs stand to be potentially disruptive in this rapidly evolving space!

4. REZILIENT 3
🤓 Permit me to nerd out for a bit. Why are #EGFR Exon 20 insertions so hard to target? On a high level, there are TWO reasons.
1⃣Steric hinderance: #EGFR Exon 20 insertions disrupt the drug-binding pocket, with a shift ofthe αC-helix into the pocket owing to the C-terminal insertions.
2⃣Preserved ATP affinity (main reason): In contrast to sensitizing #EGFR mutations (exon 19 del, L858R, L861Q), ex20ins can INCREASE ATP affinity. This creates a pharmacologic problem because the TKI must compete with abundant intracellular ATP.
📋 The PAPILLION trial showed a PFS advantage with ami+chemo vs chemo alone (HR 0.40). REZILIENT-3 may build on this and potentially show that a zipalertinib+chemo > chemo alone.
❓Questions (if trial is positive): When should we use ami+chemo over zipalertinib+chemo? What is CNS efficacy? How does the HR benefit here stack up against sunvozertinib?

⭐️ Very early data, but extremely intriguing. LB2102, a DLL3-targeted CAR-T armored with dnTGFBR2, showed 20% ORR / 70% DCR in R/R SCLC/LCNEC.
1⃣CAR-T expansion was consistent, with higher exposure associated with response.
2⃣CRS (n=6, 30%) and ICANS (n=2, 15%), w/ majority being Gr 1-2 and not leading to discontinuation of drug
3⃣Lower pre-infusion lymphocyte count (p=0.04) and higher levels of IL15 on Day 1 was associated with better clinical response (p=0.02).
4⃣Most pts ( 76%, 13/17) had DLL3 expression >90%. How does this change post DLL3 TCE exposure?

7. Small cell transformation in EGFR NSCLC
⭐️OA05.03 is a fascinating translational presentation describing the "neuroendocrine plastic (NEP)" stage
1⃣Through elegant methods of lineage tracing and multiomic analyses, the authors identified an NEP state
2⃣KEY TAKEAWAY is that over-expression of E2F1 via epigenetic remodeling (↑H3K27ac, ↓H3K27me3) at NE loci redirects E2F1 away from cell-cycle programs toward ASCL1/NE lineage programming and this is a crucial step in driving SCLC transformation.
3⃣Identification of an NEP state allows for a window of opportunity to re-direct cells before irreversible lineage commitment!

8. MDT-BRIDGE
⭐️Neoadjuvant durvalumab + chemo --> followed by serial MDT reassessment allowed 92.3% of patients to receive to curative-intent surgery or CRT, even with nearly a third of pts having borderline resectable disease
🗝️ KEY INSIGHTS:
- 74.6% overall resection rate (n = 142)
- 96.2% R0 resection
- 27.3% pCR among patients remaining resectable
- 90.1% 12-mo EFS in the resectable cohort
- 75.1% 12-mo PFS in those converted to CRT
⚡️The interesting concept here isn't prior neoadjuvant exposure. Rather it’s the dynamic treatment strategy, allowing patients to transition from surgery to definitive CRT rather than abandoning curative intent when resectability changes. This will be a heavily debated study.
@lcsmchat @OncoAlert @OncLive @LungCancerEu @Lung_Cancers @MedwatchHQ
9. NAUTIKA-1: divarasib cohort
⭐️ This is a very interesting dataset looking at neoadjuvant divarasib for stage IB-IIIB (T3N2 only; per KRAS G12C+ NSCLC
🗝️ KEY INSIGHTS: Among 20 patients enrolled, there was 42% MPR, 16% pCR, 55% ORR, and 100% R0 resection
🤔 The data are small, but provocative. For whom should we prioritize the KRAS G12Ci approach in the neoadjuvant setting, since many of these patients do respond quite well to neoadjuvant chemoIO? Should we consider KRAS G12Ci for PDL1 < 1%? Those with KEAP1 alterations? Those who are chemotherapy ineligible? Should there be a perioperative component? Should we combine with KRAS G12Ci with IO (or chemoIO)? This is hypothesis generating data!
@KRASKickers @lcsmchat @YoungLungCancer @OncoAlert @MedwatchHQ
10. IRAE prediction using machine learning
⭐️ The ENTIRE OA11 session is filled with incredible presentations, but this one really caught my eye. Can we predict who will develop severe toxicity from neoadjuvant chemoimmunotherapy in NSCLC?
1⃣In a multicenter cohort of 947 patients, grade ≥3 TRAEs occurred in 46%.
2⃣An explainable ML framework identified CatBoost as the top-performing model (AUC 0.824 in model)
3⃣Patients with Gr ≥3 TRAEs had higher MPR rates in both discovery (p=0.005) and validation (p=0.030), suggesting a potential association between TRAE severity and response!
🎯These kind of analyses are very useful for pretreatment risk stratification and adverse event monitoring! This will be need prospective validation, but is really provocative!

HONORABLE MENTIONS
1⃣PL03.08 - Ran out of time, but this is obviously a MAJOR study looking at front line T-Dxd in #HER2 #NSCLC. Big question will be positioning given approval of zongertinib in 1L setting.
2⃣OA07.02 - Ambient air pollution exposure and lung cancer prognosis. Builds on prior studies showing a concerning relationship between air quality and lung cancer prognosis.
3⃣OA13.01 - Intracranial Responders in Cerebrospinal Fluid and Peripheral-Intracranial Immune Linkage During ICI Therapy in NSCLC Brain Metastases. First, it is amazing that the authors were able to generate this dataset given complexity of acquisition and analyses involved. Will be very interesting to see the details!
4⃣OA14.05 - Ivonescimab-Chemo vs Placebo-Chemo in EGFR-TKI-Resistant, EGFR-Mutated NSCLC (HARMONi): Updated Overall Survival Analysis. Interesting study and devil will be in details given that prior IO studies (KEYNOTE-789) were negative.
5⃣OA10.03 - Sac-TMT in patients with previously treated NSCLC with alterations other than EGFR. Will be an interesting dataset to compare with TROPION-Lung05.

Three positive first-line phase III trials now shape EGFR exon 20 insertion NSCLC:
• PAPILLON: amivantamab + chemo
• WU-KONG 28: sunvozertinib
• REZILIENT 3: zipalertinib + chemo
No head-to-head winner. No clear OS winner yet. https://t.co/0jo6u0aVJa
My read: all 3 are reasonable 1L options.
In practice, sunvozertinib may become preferred for many oncologists and patients because it offers meaningful efficacy as oral monotherapy with lower treatment burden.
That is a likely practice pattern—not a proven evidence-based ranking.
Combination strategies remain strong options, especially when clinicians prioritize combination-trial data or particular patient/disease features.

288 impressions · view on X ↗😈To play devils advocate, I think FLAURA2 (for sensitizing EGFR mutations), PAPILLION, and REZILIENT3 all point towards the importance of upfront chemotherapy with EGFR inhibition.
💭My thought is that #EGFR lung cancers (esp Exon 20) really do need intensification upfront.
@EGFRResisters @EgfrUk
@jennifermarksmd 1️⃣ You are still offering EGFR inhibition + chemo with Ami/chemo, which is the larger principle.
2️⃣I do think pts with EGFR NSCLC specifically benefit from intensification upfront. Chemo is one way. I’m agnostic to whether it is the ONLY way (ami/laz) but combos needed IMO
@TejasPatilMD But do you actually though? Perhaps I’m still not over the 1L zipalertinib + chemo toxicity being what it is. I’d rather use ami + chemo.
@TejasPatilMD The biology/binding pocket is clearly different for exon20ins. I’m not sure the data can justify tki +chemo for the sake of toxicity at this time. Would have been helpful to see 1L monotherapy from zipalertinib.
1. Toxicity doesn’t necessarily keep accumulating with time.
Most selected TRAEs emerged in the first 2 years, with relatively few new events thereafter. https://t.co/ZRzPZg47JE
2. Manage toxicity rather than reflexively abandoning therapy.
Only 6% discontinued for TRAEs.
Dose reductions occurred in ~26%.
Exploratory analyses found no apparent PFS or brain-progression disadvantage across dose levels. https://t.co/nxSWCrI6Lg
3. Ask about what patients may not volunteer.
Cognition, mood, weight, edema and lipids all deserve proactive monitoring. https://t.co/T3MUnrqCew
Oh and one bonus signal for thought: hypercholesterolemia was associated with improved PFS (HR 0.50), raising the hypothesis that it could be an on-target pharmacodynamic marker.

🇰🇷 Sunday, September 13, 2026
A major session spanning SCLC and non-driver NSCLC, with several practice-changing Phase 3 readouts:
🧠 SWOG S1827 MAVERICK
Brain MRI surveillance ± PCI in SCLC
🧩 TAISHAN-302
Tam-Peli, a B7-H3 ADC, vs topotecan in relapsed SCLC

🧬 #WCLC26 Presidential Symposium 2
🇰🇷 Monday, September 14, 2026
This one is all about oncogene-driven NSCLC, with important updates across EGFR and ROS1:
🔹 ADAURA
8-year OS landmark update for adjuvant osimertinib in resected EGFR-mutant NSCLC
🔹 PAPILLON
OS with 1L amivantamab + chemotherapy in EGFR exon 20 insertion NSCLC
🔹 REZILIENT 3
Phase 3 results of 1L zipalertinib + chemotherapy in EGF

Presidential Symposium 1 looks like a fascinating Sunday morning in Seoul.
Four phase III trials. One could change a decades-old approach to brain radiation, two test a new drug class in SCLC, and one may explain why promising phase II data didn’t survive phase III.
Here’s what we know — and what we’ll learn.

Here we go with our second tweet on @iaslc #wclc26 prep!
1/6 If Presidential Symposium 1 at #WCLC26 is eclectic, Symposium 2 has a remarkably clear theme:
Targeted therapy moving earlier — and getting better.
ADAURA → PAPILLON → REZILIENT3 → ARROS-1.
Here’s what we already know — and what Monday morning in Seoul should tell us
@OncoAlert @OncBrothers @oncodaily @Jani_Chinmay @Latinamd @COlaza
Looking forward to @IASLC #WCLC26
Pleased to be a co-author of OA10.01, led by Alex Spira:
Phase 1 Global Study of Iza-Bren in Metastatic EGFR-mutated NSCLC: Results of the Randomized Dose Expansion Cohort
Iza-bren is a first-in-class EGFR×HER3 bispecific ADC that has already shown encouraging activity in EGFR-mutant NSCLC after EGFR TKIs.
At WCLC, we’ll see results from the global randomized d
Seoul in a week. Nine trials in two Presidential Symposia will answer questions we have been arguing about for a decade: whether PCI survives the MRI era in SCLC, whether topotecan is finished as a comparator once two B7-H3 ADCs report side by side, and whether exon 20 gets one standard or two. Bring your skepticism. #WCLC26 @IASLC
@oncoalert @oncodaily @larvol @tribeMDUS @sylvestercancer @oncbro
With less than two weeks to go the two Presidential Symposia at #WCLC26 got the headlines. Here are six abstracts from the oral and mini-oral sessions that matter just as much for advanced NSCLC — ranked. @IASLC @oncoalert @oncbrothers @uicc @myESMO @ASCO #LCSM https://t.co/wimvvNVUyW
6/6 So Presidential Symposium 1 gives us four very different questions:
1. Can we safely use less radiation?
2. Can B7-H3 ADCs establish a new treatment class in SCLC?
3. Why did a promising ADC + IO strategy fail in phase III?
Sometimes the most important trials tell us what to stop doing — not just what to add.
See you Sunday morning in Seoul. 🇰🇷 #WCLC26
5/6 ARROS-1
One I’m particularly looking forward to — and I’m pleased to be a co-author.
Zidesamtinib is a next-generation ROS1 inhibitor designed for potent CNS activity and resistance coverage.
Preliminary TKI-naïve ARROS-1 data were striking:
ORR 89%
Intracranial ORR 83% in a small evaluable CNS cohort.
Now WCLC brings updated efficacy and safety in the TKI-naïve population.

1️⃣ TAISHAN-302
Relapsed SCLC
⭐ Can a new strategy finally beat topotecan?
2️⃣ ARTEMIS-008
Risvutatug rezetecan vs topotecan in relapsed SCLC
⭐ ADCs challenge an old chemotherapy standard.
3️⃣ DeLLphi-309
Tarlatamab extended-interval dosing
🚨 Landmark development in ES-SCLC!
Phase 3 DeLLphi-305 has shown a statistically significant and clinically meaningful OS benefit with tarlatamab (IMDELLTRA) + durvalumab versus durvalumab alone as 1L maintenance after platinum–etoposide + durvalumab.
PFS and ORR also improved.
A potentially important new chapter in ES-SCLC maintenance therapy.

4/6 ARTEMIS-008
Another B7-H3 ADC, risvutatug rezetecan, versus topotecan.
Here we already know something important:
✅ The phase III trial met its primary overall-survival endpoint, with a statistically significant and clinically meaningful benefit.
At WCLC the question isn’t “did it work?”
It’s how much did it work?
HR, median OS, absolute benefit, PFS, durability and safety will matter.
5/6 EVOKE-03 / KEYNOTE-D46
Sacituzumab govitecan + pembrolizumab vs pembrolizumab alone in untreated metastatic NSCLC with PD-L1 ≥50%.
The early data looked promising.
But phase III tells a different story:
❌ PFS numerically favored the combination but did not reach statistical significance, and the study was discontinued.
At WCLC I want to understand why — and what the OS, subgroup and safet
3/6 PAPILLON
1L amivantamab + chemotherapy changed treatment for EGFR exon20ins NSCLC.
What we know:
PFS: 11.4 vs 6.7 months
HR 0.40
ORR: 73% vs 47%
The initial OS analysis showed a favorable but immature trend.
At WCLC: mature overall survival.
That is the missing piece.
4/6 ⚡ REZILIENT3
And immediately after PAPILLON comes a potential challenger:
zipalertinib + chemotherapy in first-line EGFR exon20ins NSCLC.
We already know from the public topline announcement:
✅ REZILIENT3 met its primary PFS endpoint.
But we don’t know the numbers.
At WCLC: the HR, median PFS, response, CNS activity, safety and OS maturity.
Back-to-back with PAPILLON, this should be fas
3/6 TAISHAN-302
Tam-peli is a B7-H3 antibody-drug conjugate being compared with topotecan in relapsed SCLC.
We know: Early-phase activity has been very encouraging.
We don’t yet know publicly: whether the phase III trial is positive.
At WCLC: OS, PFS, response durability and toxicity — and whether B7-H3 is truly ready for prime time in SCLC.
The PCI question has been answered in a contemporary phase III RCT. Final results remain embargoed until 9/13. #WCLC26 @PDBrownOnc @bslotman https://t.co/ABMuPK4xCV
2/6 MAVERICK / SWOG S1827
The question: in the MRI era, do patients with SCLC still need prophylactic cranial irradiation?
(both limited and extensive stage)
We know: PCI reduces brain metastases, but cognition and the role of modern MRI surveillance remain major concerns.
At WCLC: Can MRI surveillance safely replace PCI without compromising survival — and what happens to brain control, cognitio
I can’t wait to learn about the results of #S1827 in the presidential session on the first day of #WCLC2026 @IASLC @SWOG #PCI in Limited Stage SCLC & Extensive Stage SCLC Benefits, neurotoxicity, Early detection of lesions, role of MRI & SRS all are important questions. https://t.co/WGCEXlTLi1
2/6 ADAURA — 8-year update
We already know that 3 years of adjuvant osimertinib improves DFS and OS after resection of EGFR-mutant NSCLC.
Now comes the fascinating long-term question:
Does that benefit remain durable years after osimertinib has stopped?
At WCLC: the 8-year OS landmark and the shape of those survival curves.
This is less about establishing the standard — and more about underst

Updated overall survival data from the #HARMONi clinical trial on ivonescimab will be presented on September 15th at the @IASLC World Congress on Lung Cancer (#WCLC 2026) in Seoul #LCSM https://t.co/gZbFGP34GD
1. OA14.05 — HARMONi updated OS. Ivonescimab + chemo after a 3rd-gen EGFR TKI: PFS 6.8 vs 4.4 mo (HR 0.52), OS HR 0.76 in the July analysis. PDUFA is Nov 14. The highest-stakes number of the meeting, presented eight weeks before the FDA decides. @iaslc #wclc26 @SMMT_TX #LCSM https://t.co/MbLtwgCYYO
One of my old $SMMT writeups (2/2)
The science still holds—ivonescimab safely delivers VEGF in squamous NSCLC (HARMONi-6, Lancet). But HARMONi OS missed significance. The Real test (HARMONi-3 squamous data) still pending 2H26. Watching closely. https://t.co/2RRA5SZWpu https://t.co/KFZNBDOdvY
HARMONi (n=438, phase 3): ivonescimab + chemo nearly doubled PFS in EGFR-mutant NSCLC after TKI failure, 6.8 vs 4.4 months, HR 0.52. OS trended better, 16.8 vs 14.0 months, but the CI touched 1.01. Serious treatment-related AEs: 28% vs 15% (that's the trade-off to watch)
WCLC 2026 | HARMONi 🇰🇷
With longer follow-up, ivonescimab + chemotherapy continues to show an OS benefit after third-generation EGFR TKI progression.
The global data make this one particularly interesting to follow.

1/6 Alright! Three weeks to go @iaslc #WCLC26
Presidential Symposium 1 looks like a fascinating Sunday morning in Seoul.
Four phase III trials. One could change a decades-old approach to brain radiation, two test a new drug class in SCLC, and one may explain why promising phase II data didn’t survive phase III.
Here’s what we know — and what we’ll learn.
@OncoAlert @OncBrothers @Latinamd @COlazagasti @Jani_Chinmay #LCSM
2/6 MAVERICK / SWOG S1827
The question: in the MRI era, do patients with SCLC still need prophylactic cranial irradiation?
(both limited and extensive stage)
We know: PCI reduces brain metastases, but cognition and the role of modern MRI surveillance remain major concerns.
At WCLC: Can MRI surveillance safely replace PCI without compromising survival — and what happens to brain control, cognition and QoL?
This one could directly change practice.
3/6 TAISHAN-302
Tam-peli is a B7-H3 antibody-drug conjugate being compared with topotecan in relapsed SCLC.
We know: Early-phase activity has been very encouraging.
We don’t yet know publicly: whether the phase III trial is positive.
At WCLC: OS, PFS, response durability and toxicity — and whether B7-H3 is truly ready for prime time in SCLC.
4/6 ARTEMIS-008
Another B7-H3 ADC, risvutatug rezetecan, versus topotecan.
Here we already know something important:
✅ The phase III trial met its primary overall-survival endpoint, with a statistically significant and clinically meaningful benefit.
At WCLC the question isn’t “did it work?”
It’s how much did it work?
HR, median OS, absolute benefit, PFS, durability and safety will matter.
5/6 EVOKE-03 / KEYNOTE-D46
Sacituzumab govitecan + pembrolizumab vs pembrolizumab alone in untreated metastatic NSCLC with PD-L1 ≥50%.
The early data looked promising.
But phase III tells a different story:
❌ PFS numerically favored the combination but did not reach statistical significance, and the study was discontinued.
At WCLC I want to understand why — and what the OS, subgroup and safety data teach us.
6/6 So Presidential Symposium 1 gives us four very different questions:
1. Can we safely use less radiation?
2. Can B7-H3 ADCs establish a new treatment class in SCLC?
3. Why did a promising ADC + IO strategy fail in phase III?
Sometimes the most important trials tell us what to stop doing — not just what to add.
See you Sunday morning in Seoul. 🇰🇷 #WCLC26
@GlopesMd Hate to be missing it but looking forward to keeping up with the updates via this platform and #lcsm community!
@GlopesMd Yes! Like the Japanese 2017 Ph3 I bet this will show safe to observe and treat when metastases present. Excited to see results
Here we go with our second tweet on @iaslc #wclc26 prep!
1/6 If Presidential Symposium 1 at #WCLC26 is eclectic, Symposium 2 has a remarkably clear theme:
Targeted therapy moving earlier — and getting better.
ADAURA → PAPILLON → REZILIENT3 → ARROS-1.
Here’s what we already know — and what Monday morning in Seoul should tell us
@OncoAlert @OncBrothers @oncodaily @Jani_Chinmay @Latinamd @COlazagasti
2/6 ADAURA — 8-year update
We already know that 3 years of adjuvant osimertinib improves DFS and OS after resection of EGFR-mutant NSCLC.
Now comes the fascinating long-term question:
Does that benefit remain durable years after osimertinib has stopped?
At WCLC: the 8-year OS landmark and the shape of those survival curves.
This is less about establishing the standard — and more about understanding how durable that standard really is.
3/6 PAPILLON
1L amivantamab + chemotherapy changed treatment for EGFR exon20ins NSCLC.
What we know:
PFS: 11.4 vs 6.7 months
HR 0.40
ORR: 73% vs 47%
The initial OS analysis showed a favorable but immature trend.
At WCLC: mature overall survival.
That is the missing piece.
4/6 ⚡ REZILIENT3
And immediately after PAPILLON comes a potential challenger:
zipalertinib + chemotherapy in first-line EGFR exon20ins NSCLC.
We already know from the public topline announcement:
✅ REZILIENT3 met its primary PFS endpoint.
But we don’t know the numbers.
At WCLC: the HR, median PFS, response, CNS activity, safety and OS maturity.
Back-to-back with PAPILLON, this should be fascinating.
5/6 ARROS-1
One I’m particularly looking forward to — and I’m pleased to be a co-author.
Zidesamtinib is a next-generation ROS1 inhibitor designed for potent CNS activity and resistance coverage.
Preliminary TKI-naïve ARROS-1 data were striking:
ORR 89%
Intracranial ORR 83% in a small evaluable CNS cohort.
Now WCLC brings updated efficacy and safety in the TKI-naïve population.
The big question: could zidesamtinib ultimately move into first-line ROS1+ NSCLC?
6/6 Presidential Symposium 2 tells a larger story about where precision oncology is going:
➡️ targeted therapy after surgery
➡️ targeted therapy + chemotherapy upfront
➡️ competing strategies for the same genomic subgroup
➡️ next-generation drugs designed for the brain and resistance
We’re no longer asking simply “Can we target this alteration?”
We’re asking:
Which drug? When? In what sequence? And how early can we use it?
That’s a good sign of how far lung cancer has come. #WCLC26
