Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to purpose of this study is to assess if regorafenib is active enough, in terms of 6-month progression-free rate, to warrant further comparative studies in patients with RAS-mutant advanced colorectal cancer who have progressed after first-line oxaliplatin-based chemotherapy plus bevacizumab.
