Multiple recent studies evaluate different immunotherapy approaches for advanced NSCLC, including long-term benefits for nivolumab plus ipilimumab with chemotherapy in PD-L1-negative tumors, limited advantages from PD-(L)1 rechallenge strategies, and early positive signals from combining TIGIT and PD-1 inhibitors in PD-L1-high patients.
Key oncology developments include a $315 million partnership between Astellas and Vir for the prostate cancer T-cell engager VIR-5500, with updated phase 1 data showing an 82% PSA50 rate. The FDA accepted a filing for Ono Pharmaceuticals' tirabrutinib seeking accelerated approval in primary central nervous system lymphoma. Research findings also identified a new kidney cancer biomarker and showed promising results for the TRK inhibitor repotrectinib and the breast cancer triple therapy gedatolisib plus palbociclib and fulvestrant.
Multiple oncology trials present recent results, including cabozantinib-nivolumab activity in non-clear cell RCC, savolitinib efficacy in MET-amplified gastric cancer, and induction nivolumab feasibility in HPV-driven oropharyngeal cancer.
Three trials show ultra-low-dose checkpoint inhibitors retain efficacy with reduced toxicity and dramatically lower costs. DELII and Patil et al. trials tested low-dose nivolumab in solid tumors and HNSCC; NIVIPIT tested intratumoral low-dose ipilimumab in melanoma.
FDA approves AstraZeneca and Daiichi Sankyo's Datroway for first-line TNBC patients not eligible for PD-1/L1 inhibitors, based on Phase III TROPION-Breast02 data showing a 21% reduction in risk of death versus chemotherapy.
Phase 3 BREAKWATER found encorafenib plus cetuximab plus FOLFIRI improved PFS and response in first-line BRAF V600E-mutant metastatic colorectal cancer. OS data remain immature.
MSD said sacituzumab tirumotecan improved overall survival and progression-free survival in the Phase III TroFuse-005 trial in endometrial cancer. The study also met its objective response rate endpoint.
Tumour-infiltrating lymphocyte therapy has shown durable responses in refractory melanoma, including a 31.4% objective response rate in phase II data. The 2024 FDA approval of Lifileucel marked a milestone as regulators in other markets continue reviews.
The FDA has accepted for review a supplemental application for taletrectinib in advanced ROS1-positive NSCLC, with a PDUFA date of January 4, 2027. Updated TRUST-I and TRUST-2 data showed high response rates, durable responses and no new safety signals.
Sensei Biotherapeutics dosed the first patient in a Phase 1b/2 trial of PIKTOR (sapanisertib + serabelisib) in HR+/HER2- advanced breast cancer. The multi-node PI3K/AKT/mTOR inhibitor previously showed a 47% overall response rate in a Phase 1b trial.
