Adults who were histologically diagnosed and never treated for extensive-stage small cell lung cancer (ES-SCLC) were enrolled. Eligible Patients were randomly assigned (1:1) to receive four cycles (21 days as one cycle) of intravenous carboplatin (area under the curve of 5 mg/mL per min, day 1 of each cycle) and etoposide (100 mg/m² of body-surface area, on days 1-3 of each cycle) with either socazolimab (5 mg/kg, day 1 of each cycle) or matching placebo, following maintenance therapy with socazolimab or placebo. From July 15, 2021, to May 12, 2022, 498 eligible patients were randomly assigned to receive socazolimab (250 patients) or placebo (2Signal transduction and targeted therapy28https://www.ebi.ac.uk/biostudies/studies/S-EPMC11725569biostudies-literatureA multicenter, randomized, double-blind, placebo-controlled phase 3 study of Socazolimab or placebo combined with carboplatin and etoposide in the first-line treatment of extensive-stage small cell lung cancer.PMC11725569Huang DWu LHu YHan LSocazolimab Study GroupYu GYi TDai XWang QChen ZCheng PWong MSun HWu YYu XTan LLi JChen JLi BXLi NZhang WLi XLi YZhang TZhang ZHe ZLu SYang RShi JMa DfalseA multicenter, randomized, double-blind, placebo-controlled phase 3 study of Socazolimab or placebo combined with carboplatin and etoposide in the first-line treatment of extensive-stage small cell lung cancer.This is a randomized, double-blind, placebo-controlled phase 3 clinical trial (ClinicalTrials.gov, NCT04878016) conducted in 54 hospitals in China.
