Amgen, AstraZeneca Team Up; Death Risk in Small Cell Lung Cancer Cut by 58% — BigGo Finance
Amgen and AstraZeneca's immunotherapy combination reduced death risk by 58% in extensive-stage small cell lung cancer, extending median survival to 21.1 months. The trial showed 80% one-year survival with the combo vs. 53% with Imfinzi alone. Amgen's Imdelltra sales grew 115% YoY to $288M in Q2, with 2025 sales at $627M. The results may expand Imdelltra's use and redraw the competitive landscape for first-line maintenance therapy.
