NCT ID NCT04063163

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This Phase 3 trial tested whether adding an experimental immunotherapy drug called HLX10 to standard chemotherapy could help people with extensive-stage small cell lung cancer live longer. The study enrolled 585 people who had not received prior treatment. Participants were randomly assigned to receive either HLX10 plus chemo or a placebo plus chemo. The main goal was to see if the combination improved overall survival.
