Clinical Trial Summary

The purpose of this study is to observe and evaluate the efficacy and safety of Sintilimab for Consolidation Therapy After Radical Concurrent Chemoradiotherapy for Locally Advanced Unresectable Esophageal Squamous Cell Carcinoma

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 single-arm, open-label, phase II trial of Sintilimab for consolidation therapy after radical concurrent chemoradiotherapylocally advanced esophageal squamous cell carcinoma.The purpose of this study is to observe and evaluate the efficacy and safety of Sintilimab for consolidation therapy after radical concurrent chemoradiotherapy for locally advanced unresectable esophageal squamous cell carcinoma.
