REVIVE study: a prospective observational study in chemotherapy after nivolumab therapy for advanced gastric cancer

Nivolumab is an increasingly used standard care treatment for heavily pretreated patients with advanced gastric cancer, with increasing clinical use in Japan. Data from retrospective studies on various tumors have shown the objective response rate to cytotoxic chemotherapy potentially improves after an exposure to immune checkpoint inhibitors. Based on these data, we conducted the multicenter observational REVIVE study to evaluate the efficacy and safety of cytotoxic chemotherapy in nivolumab-refractory or nivolumab-intolerant patients with advanced gastric cancer. Patients who are refractory or intolerant to nivolumab and scheduled to receive irinotecan monotherapy, oxaliplatin combination treatment or oral trifluridine/tipiracil hydrochloride therapy will be included. The primary end point is overall survival of nivolumab-pretreated patients with advanced gastric cancer after the cytotoxic chemotherapy.
