The phase III REZILIENT3 trial met its primary endpoint, with the investigational agent zipalertinib plus chemotherapy significantly improving PFS over chemotherapy alone for first-line advanced NSCLC with EGFR exon 20 insertion mutations. Conversely, the phase III SKYSCRAPER-03 trial showed no PFS benefit from adding the investigational anti-TIGIT antibody tiragolumab to atezolizumab versus standard durvalumab for patients with unresectable NSCLC post-chemoradiation. Additionally, new biomarker analyses from the CheckMate 77T trial were published, detailing correlative work including ctDNA clearance and post-surgical MRD.

“Another phase III trial fails to improve outcomes over the PACIFIC regimen for stage III NSCLC. This time SKYSCRAPER-03, which compared post CRT Tiragolumab + Atezolizumab vs Durvalumab.”

Separately, an exploratory analysis of CAPItello-291 suggests PTEN IHC may identify patients with HR+/HER2- advanced breast cancer who benefit from capivasertib, even without NGS-detected alterations. In first-line advanced TNBC, investigational ivonescimab plus a taxane demonstrated an 80% ORR in a small phase 2 study.

“ORR 27%, median rwPFS 6.5 mo, OS 14.2 mo. Longer rwPFS in those who had stopped T-DXd for reasons other than progression. No ILD on rechallenge.”

“First-line ivonescimab+taxane in advanced TNBC (n=36): ORR 80%, mPFS 15.2 mo. In CPS<10 disease, ORR was 79.3% and mPFS 13 mo—the key signal.”

“Most interestingly, among PTEN-deficient tumors without PIK3CA/AKT1/PTEN alterations detected by NGS: mPFS 16.2 vs 4.6 mo HR 0.43 (95% CI 0.15–1.05)”

In hepatocellular carcinoma (HCC), the phase III TORCH trial found that TACE plus thermal ablation significantly improved median OS to 88.6 months versus 35.1 months for TACE alone in unresectable, liver-confined disease. Additionally, Depth of Response (DpR) is being discussed as a novel efficacy endpoint in HCC, with data from trials like IMbrave150 and HIMALAYA showing its correlation with overall survival.

“The control arm is not how we treat high-risk rectal cancer in the US. We already know TNT is better than CRT → surgery → adjuvant chemotherapy based on OPRA's modern benchmark.”

“TORCH is a little tricky to interpret because it essentially compares TACE deliberately left incomplete with TACE followed by ablation. In some ways, that feels more like “inadequate local therapy” vs “adequate local therapy” than a clean test of what TACE itself adds.”

The LITESPARK-011 trial, published in The Lancet, showed the investigational combination of belzutifan plus lenvatinib improved median PFS to 14.8 months versus 10.7 months for cabozantinib (HR 0.70) in advanced ccRCC after anti-PD-(L)1 therapy, with no significant difference in OS at interim analysis. In prostate cancer, a new analysis from the PROpel trial highlighted the greatest benefit from olaparib plus abiraterone in mCRPC patients with BRCA2 mutations. Additionally, the largest real-world dataset on Lu-PSMA-617 (n=3,709) showed a median imaging PFS of 7.6 months, similar to the VISION trial, in an older, more heavily pretreated population.

“Our original article — higher LAG-3 expression in RCC was associated with a distinct immune-rich TME and improved rwORR to 1st line IO, serving as a potential biomarker of early IO response.”

The FDA approval is based on the Phase 3 EXCALIBER-RRMM trial, which showed the iberdomide regimen achieved a 41% MRD-negative complete response rate versus 21% for the control arm (daratumumab, bortezomib, dexamethasone); PFS data are still immature. Commentary also highlighted a study of an investigational bispecific BCMA/GPRC5D CAR-T for extramedullary myeloma, which showed a 97% ORR but a median PFS of only 5.8 months.

“Iberdomide (first CELMoD) now @US_FDA ✅ based off EXCALIBER-RRMM in 2L and beyond for R/R #MultipleMyeloma. IberDd: - Improved MRD (41% vs. 21%) - PFS still immature - AEs: Cytopenias and Infections ”

Other commentary focused on therapy-related hematologic malignancies, noting that the IDH2 R140Q group is characterized by DNA hypermethylation and enrichment for focal IKZF1 deletions, and that IMiD discontinuation may lead to regression of secondary leukemia in some cases.
