Perioperative Cadonilimab Combined With Neoadjuvant Chemotherapy in Resectable Esophageal Squamous Cell Carcinoma (ESCC)

Официальное название

A Randomized, Controlled, Multi-center Phase II/III Clinical Trial of Perioperative Cadonilimab Combined With Neoadjuvant Chemotherapy in Patients With Resectable Locally Advanced Thoracic Esophageal Squamous Cell Carcinoma (ESCC)

Обзор

This is a randomized, controlled, multi-center phase II/III study. All patients are resectable locally advanced thoracic esophageal squamous cell carcinoma (ESCC), Eastern Cooperative Oncology Group (ECOG) performance status 0-1. The purpose of this study is to evaluate the efficacy and safety of perioperative Cadonilimab combined with neoadjuvant chemotherapy versus neoadjuvant chemotherapy in patients with resectable ESCC.
