A Phase III Study of Fruquintinib in Combination With Paclitaxel in Second Line Gastric Cancer(FRUTIGA)

A Phase III Study to Evaluate the Efficacy and Safety of Fruquintinib in Combination With Paclitaxel Versus Paclitaxel Alone in Second Line Gastric Cancer

Fruquintinib once daily in 4 weeks treatment cycle (three weeks on and one week off) in combination with Paclitaxel 80mg/㎡（day1, 8, 15 of 4 weeks cycle) was well tolerated and demonstrated encouraging preliminary clinical antitumor activity in patients with advanced GC in ph1b/2 study. This study is aimed to evaluate the efficacy and safety of Fruquintinib in combination with Paclitaxel in the treatment of patients with aGC who have progressed after first line standard chemotherapy.

This is a randomized, double-blind, placebo-controlled, multicenter Phase III clinical trial to compare the efficacy and safety of Fruquintinib combined with Paclitaxel versus Paclitaxel alone in patients with advanced gastric cancer who have progressed after first-line standard chemotherapy. After checking eligibility criteria, subjects will be randomized into Fruquintinib combined with Paclitaxel group (treatment group) or placebo combined with Paclitaxel group (control group) in a ratio of 1:1. Primary Efficacy Endpoint: Overall Survival (OS), Progression free survival (PFS) (According to RECIST Version 1.1). Secondary Efficacy Endpoints: Objective Response Rate (ORR), Disease Control Rate (DCR), Duration of Response (DOR), EORTC QLQ-C30 (V3) .Safety and tolerance will be evaluated by incidence, severity and outcomes of AEs and categorized by severity in accordance with the NCI CTC AE Version 4.03.
