5. Study Description
Brief Summary
This study is a single-arm, single center study. The purpose of this study is to evaluate the efficacy and safety of FMT capsules XBI-302 combined with Nivolumab in the treatment of anti-PD-1/L1 resistant gastric cancer.
Detailed Description
The primary purpose of this single-arm, open-label, single center trial is to evaluate the efficacy and safety of XBI-302 combined with Nivolumab in the treatment of anti-PD-1/L1 resistant gastric cancer.
During treatment period, all eligible subjects will receive XBI-302 with Nivolumab following gut preparation. The imaging evaluation of efficacy will be performed every 6 weeks.
