A Randomized, Active-Controlled, Double-blind, Multicenter, Phase 3 Clinical Study of Ivonescimab in Combination with mFOLFOX6 (Oxaliplatin, Leucovorin and 5-Fluorouracil) versus Bevacizumab in Combination with FOLFOX for the First-line Treatment of Metastatic Colorectal Cancer(HARMONi-GI3)
This trial will be performed as a phase 3, randomized, active-controlled, double-blind, multiregional study comparing Ivonescimab in combination with mFOLFOX6 (Oxaliplatin, Leucovorin and 5-Fluorouracil) versus Bevacizumab in combination with mFOLFOX6 in patients with metastatic colorectal cancer who have not previously received systemic therapy for metastatic disease. Approximately 600 patients will be randomly assigned to the 2 treatment groups in a 1:1 ratio. Each enrolled subject will receive an intravenous infusion of the Ivonescimab/Bevacizumab Plus mFOLFOX6 (Q2W, up to 8 cycles) in treatment periods per the randomization schedule. Afterward, Ivonescimab/ Bevacizumab Plus 5-Fluorouracil and Leucovorin will be used for maintenance treatment (administered on Day 1 of each cycle, Q2W) for up to 2 years.
