Summary

The study is an double blind, randomized, multicenter phase 3 trial. The efficacy analyses are based on 570 Chinese patients with RAS wt mCRC treated with mFOLFOX-6 ± cetuximab. Study treatment continues until disease progression or unacceptable toxicity (ie, not for a fixed number of courses). The primary endpoint of the study is progression-free survival (PFS) time according to RECIST 1.0; key secondary endpoints include overall survival (OS) time, overall response rate (ORR), and safety/tolerability.
