A Phase Ib Study of Fruquintinib in 3rd Line mCRC

A Randomized, Open-label Phase Ib Trial of Fruquintinib "4mg Once Daily Continuous"Versus "5mg Once Daily 3wks on/1wk Off" in Patients With Metastatic Colorectal Carcinoma as 3rd Therapy

Fruquintinib is a novel oral small molecule compound discovered and developed by Hutchison MediPharma that selectively inhibits vascular endothelial growth factor receptors (VEGFR) 1, 2, and 3 and has demonstrated potent inhibitory effects on multiple human tumor xenografts.Based on first-in-human study, both 4mg QD and 5mg 3wks on/1wk off are safety and efficacy, this phase Ib study is to evaluable the safety, tolerability and efficacy of these 2 regimens with mCRC failed 2nd therapy or more and to determine the recommended dose and regimen in phase II/III study.

This is a phase Ib, randomize, interventional, open-label, multicenter study to provide fruquintinib to subjects diagnosed with metastatic colorectal cancer who have failed after standard therapy and for whom no therapy alternatives exist.

The primary endpoint of this study will be safety.
