Amgen's Lung Cancer Drug Combination Offers Significant Survival Benefit in Trial
Amgen's Imdelltra combined with AstraZeneca's Imfinzi showed a 58% reduction in death risk for extensive-stage small cell lung cancer patients, increasing median survival to 21.1 months. The study, presented at the European Society for Medical Oncology Congress, suggests potential for Imdelltra as a first-line maintenance therapy. Imdelltra reported $288M in Q2 2023 sales and $627M in 2025 global sales.
