What the trial is, and whether it could suit you
This study is to evaluate the safety and efficacy of intraperitoneal injection of immune checkpoint inhibitor combined with zoledronic acid for the treatment of malignant ascites in gastric cancer.
This study is a phase Ib/II clinical study to evaluate the safety and efficacy of intraperitoneal injection of immune checkpoint inhibitors in combination with zoledronic acid in the treatment of malignant ascites in gastric cancer, which consists of two phases, firstly, the phase Ib safety study, which adopts the '3+3' drug-escalation experimental design, and after determining the safe and tolerable dose, it will proceed to the second part of the phase II efficacy study. The Phase II study was designed by Simon's two-stage approach to evaluate the efficacy of immune checkpoint inhibitors in combination with zoledronic acid in the treatment of malignant ascites in gastric cancer.
