Summary
Brief summary
This is a randomized, double-blind multi-center, phase III study comparing the efficacy and
safety of sintilimab or placebo in combination with chemotherapy as first-line treatment in
subjects with unresectable, locally advanced recurrent or metastatic esophageal squamous cell
carcinoma.

After the interim analysis conducted by the iDMC, an open-label assignment of experimental
arm therapy will continue in regions outside of China, in order to further evaluate the
efficacy and safety of sintilimab in combination with chemotherapy in subjects representing
the western population with advanced esophageal squamous cell carcinoma
