Brief Summary

The combination of immune checkpoint inhibitors and platinum containing dual drugs are more used as a first-line therapeutic approach for patients diagnosed with advanced gastric cancer for its superior efficacy. However, there are no standard recommendations for subsequent treatment after progression on first-line therapy. Here, the investigators conduct this open-label, monocenter, single arm phase II study to evaluate whether sintilimab in combination with irinotecan, leucovorin folinate and fluorouracil can be the salvage therapy for patients diagnosed with unresectable or metastatic gastric cancer progression on first-line therapy. Patients participated in this study will receive sintilimab 3mg/kg for patients with body weight<60kg or 200mg for patients with body weight ≥ 60kg, plus irinotecan 180mg/m2 intravenous infusion, leucovorin folinate 400mg/m2 intravenous infusion and fluorouracil 400mg/m2 intravenous injection followed by 2400mg/m2 intravenous infusion for 48 hours, repeated every two weeks. The primary endpoint is progression-free survival (PFS). The investigators estimated that 40 patients were necessary. Secondary endpoints include overall survival, objective response rate, disease control rate and safety for unresectable or metastatic gastric cancer.
