A Phase III Trial Evaluating Fruquintinib Efficacy and Safety in 3+ Line Colorectal Cancer Patients （FRESCO)

A Randomized, Double-blind and Placebo-controlled Phase III Trial Comparing Fruquintinib Efficacy and Safety vs Best Support Care (BSC) in Advanced Colorectal Cancer Patients Who Have Failed at Least Second Lines of Chemotherapies

Fruquintinib administered at 5mg once daily(QD) in 4 weeks treatment cycle (three weeks on and one week off) was well tolerated and demonstrated encouraging preliminary clinical antitumor activity in patients with metastatic colorectal cancer (CRC) in phase Ib and phase 2 study. This study is aimed to evaluate the efficacy and safety of Fruquintinib in the treatment of patients with metastatic CRC who have progressed after second line or above standard chemotherapy

This is a randomized, double-blind, placebo-controlled, multicenter Phase III clinical trial to compare the efficacy and safety of Fruquintinib plus BSC versus placebo plus BSC in patients with metastatic colorectal cancer who have progressed after second-line or above standard chemotherapy. After checking eligibility criteria, subjects will be randomized into Fruquintinib plus BSC group (treatment group) or placebo plus BSC group (control group) in a ration of 2:1. Primary Efficacy Endpoint: Overall Survival (OS). Secondary Efficacy Endpoints: Progression free survival (PFS) (According to RECIST Version 1.1), Objective Response Rate (ORR), Disease Control Rate (DCR), . 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 4.0.
