Tislelizumab in Combination With Pre-operative CRT Versus SOC for Locally Advanced G/GEJ Adenocarcinoma

Официальное название

Tislelizumab in Combination With Pre-operative Chemoradiotherapy Versus SOC for Patients With Locally Advanced Gastric/Gastroesophageal Junction Adenocarcinoma: a Multicenter, Randomized, Open-label, Phase IIB Trial

Обзор

The purpose of this study is to evaluate the efficacy of Tislelizumab in the neoadjuvant (prior to surgery) or adjuvant (after surgery) treatment of previously untreated adults with gastric and gastroesophageal junction (GEJ) adenocarcinoma. The primary study hypotheses are that: Neoadjuvant and adjuvant Tislelizumab plus chemoradiotherapy, followed by adjuvant Tislelizumab and chemotherapy is superior to neoadjuvant chemoradiotherapy or chemotherapy, followed by adjuvant chemotherapy in terms of rate of Pathological Complete Response (pathCR) at the time of surgery.
