BioNTech and Bristol Myers Squibb report Phase 2 lung cancer combo data

BioNTech and Bristol Myers Squibb announced results from the global Phase 2 ROSETTA Lung‑107 trial of pumitamig plus docetaxel in metastatic non‑small cell lung cancer patients who progressed after first‑line immunotherapy plus chemotherapy. The study of 50 patients showed a confirmed objective response rate of 36.7% and a median progression‑free survival of 6.9 months. Safety was manageable, with treatment‑related adverse events in 52.0% of patients and grade ≥ 3 events in 18.0%. The data were presented at the ESMO 2026 Congress and will inform ongoing Phase 3 programs.

The company says the results support continued advancement of pumitamig in multiple Phase 3 lung‑cancer trials, potentially expanding treatment options beyond docetaxel in the second‑line setting (). Investors should watch for subsequent trial readouts that could affect the valuation of both firms.
