A combination of Amgen's Imdelltra and AstraZeneca's Imfinzi reduced the risk of death by 58% in patients with first-line extensive-stage small cell lung cancer, one of the most aggressive and difficult-to-treat forms of the disease, according to trial data presented at the ESMO oncology congress.

Nearly 80% of patients receiving the Imdelltra-Imfinzi combination were alive at one year, compared with 53% of patients treated with durvalumab, the AstraZeneca immunotherapy, alone. Progression-free survival was more than tripled in the combination arm relative to the control group.

The results were presented at the European Society for Medical Oncology meeting, a major oncology conference running October 23 to 27, 2026. The findings reinforce the potential for combining Amgen's bispecific T-cell engager Imdelltra with checkpoint immunotherapy as a first-line treatment standard in a cancer type that has historically offered patients limited survival options.
