Treatment of Refractory Colorectal Cancer: Regorafenib vs. TAS-102

Abstract

Purpose of Review

This paper reviews the development, mechanism of action, clinical efficacy, and safety of regorafenib and TAS-102. Through this review, we aimed to help clinicians make an appropriate choice in patients who progressed after standard therapies.

Recent Findings

Regorafenib and TAS-102 have shown superior survival results compared with placebo in refractory metastatic colorectal cancer (mCRC). In the phase III CORRECT study, regorafenib showed significant improvement in overall survival (OS) and progression-free survival (PFS). TAS-102 was associated with OS and PFS benefit as well in the phase III RECOURSE study. However, the toxicity profiles were quite different between the two agents.

Summary

Regorafenib and TAS-102 are approved for the management of refractory mCRC. Optimal treatment sequence for using these two novel agents is not defined yet. Safety profiles and patient's condition should be considered before using these two agents in clinical settings. Further investigation is needed to identify the predictive biomarkers of both agents. These results will allow patients to benefit more from regorafenib and TAS-102.
