Description
This study is a Global Phase 3, open-label, multicenter study designed to evaluate the efficacy and safety of BL-M14D1 in combination with atezolizumab compared with standard-of-care therapy in adult participants with previously untreated extensive-stage small cell lung cancer (ES-SCLC). Standard-of-care therapy consists of carboplatin plus etoposide chemotherapy and atezolizumab, followed by maintenance treatment with atezolizumab with or without lurbinectedin.
