Официальное название

A Single-arm, Open-label, Multicenter Phase 2 Study to Evaluate XELOX + Tislelizumab in Combination With Doxorubicin Hydrochloride Liposome Injection （XELOX+PD-1+PLD）as Neoadjuvant Therapy for Resectable Gastric Cancer

Обзор

This is a signle-arm, multi-center, open-lable, phase II study. The objective is to evaluate the effectiveness and safety of tislelizumab + oxaliplatin + capecitabine + PLD in the neoadjuvant treatment of resectable gastric adenocarcinoma.

Подробное описание

This single-arm, multicenter, open-label study plan to enroll patients with resectable stage III gastric adenocarcinoma to recieve tislelizumab + oxaliplatin + capecitabine + PLD regimen for 2 or 4 cycles, radical resection will be performed after neoadjuvant therapy. Radiological evaluation will be performed every 2 cycles to evaluate the resectability of tumor. Survival follow-up will be performed after surgery, until patient's withdrawal of informed consent, loss to follow-up or death, whichever comes first.
