Preoperative Anti-PD-1 Antibody Combined With Chemoradiotherapy for Locally Advanced Squamous Cell Carcinoma of Esophagus — PALACE-1  

Esophageal Squamous Cell Carcinoma Clinical Trial

Official title:
A Phase Ib Study of Pre-Operative Pembrolizumab + Chemoradiation in Patients With Locally Advanced Esophageal Squamous Cell Carcinoma

Clinical Trial Summary

This study will evaluate the safety and feasibility of preoperative immune checkpoint therapy with concurrent chemoradiotherapy in patients with locally advanced esophageal squamous cell carcinoma. And this study will provide valuable information for further clinical trials of preoperative pembrolizumab and other immune checkpoint therapy in esophageal cancer treatment.

Clinical Trial Description

Esophageal cancer ranks the eighth most common cancer (the fifth most common cancer in China), while ESCC is the most common subtype in Asia (more than 90 % in china). Radical resection is thought to be the mainstay of esophageal cancer treatment and preoperative CRT is well applied in treating locally advanced esophageal cancer. In a multicohort, phase IB study, pembrolizumab was used in 23 unresectable esophageal cancer patients. In this clinical trial, the incidence of grade 3 treatment-related adverse events was 39 % without the appearance of grade 4 and higher-grade adverse event, while the overall response rate reached 30 %. The safety of immune checkpoint therapy for unresected esophageal cancers using nivolumab, a different PD-1 monoclonal antibody, has also been confirmed by high quality clinical trials. This study will evaluate the safety and feasibility of preoperative immune checkpoint therapy using pembrolizumab with concurrent chemoradiotherapy in patients with locally advanced esophageal squamous cell carcinoma. And this study will provide valuable information for further clinical trials of preoperative pembrolizumab and other immune checkpoint therapy in esophageal cancer. ;
