Unfortunately, other Phase III clinical Study (GEM+S-1 vs GEM vs S-1) have been started in Japan.
To assess the usefulness of Gemcitabine plus S-1 therapy based on the antitumor effect and survival period. By performing a phase I/II study of this combination in patients with inoperable or with postoperative pancreatic cancer.
Condition or disease
Drug: GemcitabineDrug: S-1
Phase 1Phase 2
A multicenter Open-label, single-arm, phase I/II clinical trial is conducted on patients with histological stage IV Pancreatic cancer given gemcitabine plus S-1. The usefulness of this regimens as 1st line therapy for pancreatic cancer was evaluated by the disease-free survival(DFS), median survival time (MST), incidence and severity of adverse event.
