Objectives

Primary Objectives Part 1: To evaluate the safety and tolerability of MK-1084, cetuximab, and mFOLFOX6. Part 2: To compare the progression-free survival (PFS) of MK-1084, cetuximab, and mFOLFOX6 with or without mFOLFOX6 and bevacizumab, as assessed by a blinded independent central review (BICR) according to RECIST version 1.1 (Reactive Criteria for Response in Solid Tumors 1.1). Secondary Objectives – Part 2 • To compare the objective response rate (ORR) of MK-1084, cetuximab, and mFOLFOX6 with or without mFOLFOX6 and bevacizumab, as assessed by BICR according to RECIST 1.1. • To compare the overall survival (OS) of MK-1084, cetuximab, and mFOLFOX6 with or without mFOLFOX6 and bevacizumab. • Assess the duration of response (DOR) of MK-1084, cetuximab, and mFOLFOX6 compared to mFOLFOX6 with or without bevacizumab, as assessed by BICR according to RECIST 1.1. • Assess the safety and tolerability of MK-1084 with cetuximab and mFOLFOX6. • Assess the mean changes since baseline of MK-1084 and mFOLFOX6 plus cetuximab compared to mFOLFOX6 with or without bevacizumab. • Assess the time to deterioration of MK-1084, cetuximab, and mFOLFOX6 compared to mFOLFOX6 with or without bevacizumab.
