Imdelltra DLL3 therapy posts overall survival win for first-line small cell lung cancer
Amgen’s DLL3 T‑cell engager Imdelltra showed an overall survival win in the phase 3 DeLLphi‑305 trial for first-line small cell lung cancer, supporting earlier use against an aggressive disease. The study builds on DeLLphi‑303 ES‑SCLC maintenance data with a 25.3‑month median OS and a full nod converted from earlier go-ahead last year after DeLLphi‑304.
