About this study

Official title: XELOX and Bevacizumab in Combination With Tislelizumab for First-Line Treatment of Patients With MSS/pMMR RAS-mutated Metastatic Colorectal Cancer (mCRC): A Single-arm, Phase II Study.

The goal of this clinical trial is to compare XELOX +Bev +Tislelizumab with standard chemotherapy，in MSS/pMMR-type RAS-mutated metastatic colorectal adenocarcinoma. The main questions it aims to answer are efficacy and safety of the regimen of XELOX +Bev +Tislelizumab. The investigators want to transform ras-mutated colorectal cancer into a "hot tumor" through the combination of anti-vascular therapy and chemotherapy, and then achieve better therapeutic effect through the combination with immunotherapy. Participants will receive the regimen of XELOX +Bev +Tislelizumab.

Conditions: Tislelizumab, Bevacizumab, Oxaliplatin, Capecitabine, MSS/pMMR, Metastatic Colorectal Cancer (mCRC)
Being tested: Tislelizumab+Bevacizumab+Oxaliplatin+Capecitabine
Keywords: Single-arm, Phase II
Medical subject headings: Colorectal Neoplasms
