AstraZeneca lung cancer drug combo boosts survival in late
Amgen's Imdelltra and AstraZeneca's Imfinzi combo improved survival in a late-stage lung cancer trial. The combo also enhanced progression-free survival and response rate. Imdelltra, approved for extensive-stage small-cell lung cancer, generated $513M in 2023 sales for Amgen, with cancer therapies making up 23% of its total sales. AstraZeneca has faced recent setbacks in other drug trials.
