Final analysis of camrelizumab plus chemotherapy for untreated advanced or metastatic esophageal squamous cell carcinoma: The ESCORT-1st trial

The interim analysis of the randomized phase 3 ESCORT-1st study demonstrated significantly longer overall survival (OS) and progression-free survival (PFS) for camrelizumab-chemotherapy than placebo-chemotherapy in untreated advanced/metastatic esophageal squamous cell carcinoma (ESCC). Here, we present the final analysis of this study and investigate potential indicators associated with OS.
