The Purpose of This Study is to Evaluate the Efficacy and Safety of Sintilimab in Combination With Xelox as Neoadjuvant Therapy for Patients With Resectable Locally Advanced Gastric or Gastroesophageal Adenocarcinoma.

A Prospective, Multicenter, Single-armed, Phase II Study Evaluating Efficacy and Safety of Neoadjuvant Sintilimab in Combination With Capecitabine and Oxaliplatin (XELOX) in Patients With Resectable Locally Advanced Gastric or Gastroesophageal Adenocarcinoma.

Sintilimab in Combination With Capecitabine and Oxaliplatin (XELOX) as Neoadjuvant Therapy in patients With Resectable Locally Advanced Gastric Cancer

Study Overview

• Status: Unknown
• Conditions: Gastric Cancer
• Intervention / Treatment: Drug: Sintilimab; Drug: Oxaliplatin; Drug: Capecitabine

Detailed Description

This prospective, multicenter, single-armed, phase II study will evaluate efficacy and safety of Sintilimab in combination with Xelox (Oxaliplatin 130mg/m2 iv d1 Q3w and Capecitabine 1000mg/m2 po Bid d1-14 Q3W) as neoadjuvant therapy in patients with resectable locally advanced gastric or gastroesophageal adenocarcinoma(G/GEJ AC). Newly diagnosed, treatment naïve patients with resectable locally advanced gastric or G/GEJ AC will be eligible to receive up to 3 cycles of sintilimab plus Xelox regimen as neoadjuvant therapy. Following radical gastrectomy will be performed within one to four weeks since last dosing for patients with resectable cancer after radiological evaluation.
