Summary

This study compares a new drug, serplulimab, combined with chemotherapy, against an existing drug, atezolizumab, also with chemotherapy, for people with extensive-stage small cell lung cancer who haven't had treatment before. The goal is to see which combination works better at controlling the cancer and improving survival. About 200 adults in the US are taking part.
