Brief summary: The purpose of this study is to observe and evaluate the efficacy and safety of SHR-1210 vs placebo as consolidation chemotherapy after radical concurrent chemoradiotherapy for unresectable locally advanced ESCC.

Detailed description: In China, the incidence of esophageal cancer has declined in recent years, but the mortality rate has been ranked fourth. Morbidity and mortality were ranked sixth and fourth in all malignancies, respectively. Therefore, esophageal cancer has always been a major malignant tumor that threatens the health of our residents. We designed a multicenter, randomized, double-blind, open-label phase II clinical trial of anti-PD-1 antibody SHR-1210 versus placebo as consolidation chemotherapy (CCT) after radical concurrent chemoradiotherapy for unresectable locally advanced esophageal squamous cell carcinoma (ESCC).The purpose of this study is to observe and evaluate the efficacy and safety of SHR-1210 vs placebo as consolidation chemotherapy after radical concurrent chemoradiotherapy for unresectable locally advanced ESCC.
