Phase 3 Study Comparing PF-08634404 Plus Chemotherapy to Bevacizumab Plus Chemotherapy for Adults With Advanced Metastatic Colorectal Cancer

What this Trial Is About

Researchers are evaluating a new medicine called PF-08634404 combined with chemotherapy for adults with colorectal cancer that has spread to other parts of the body. The study aims to understand how well this new combination works compared to an existing treatment using Bevacizumab with chemotherapy. The study is a phase 3, double-blind, randomized trial focusing on treatment effectiveness and safety in participants who have not received prior systemic therapy for metastatic disease. Participants are randomly assigned to one of two groups. One group receives PF-08634404 with chemotherapy, and the other group receives Bevacizumab with chemotherapy. Both treatments are given through intravenous IV infusions in cycles. Treatment continues as long as it helps and side effects are manageable. Treatments are administered at clinical sites by trained staff. Participants will have regular visits for treatment, health evaluations, and various tests. After stopping treatment, there is a follow-up visit about 30 to 37 days later to review health and side effects. Further follow-up occurs every 12 weeks by phone, in person, or via health record review to monitor health status and any new treatments. The study duration for each participant is approximately 33 months. Researchers will measure progression-free survival, overall survival, response rates, quality of life, and monitor safety throughout the study.
