Study of Pumitamig Plus Chemotherapy Compared to Bevacizumab Plus Chemotherapy in Adults With Untreated, Unresectable, or Metastatic Colorectal Cancer

What this Trial Is About

This trial studies participants with previously untreated, unresectable, or metastatic colorectal cancer. It evaluates the safety and effectiveness of pumitamig combined with chemotherapy compared to bevacizumab combined with chemotherapy. The study includes participants who do not have specific genetic markers like dMMR, MSI-H, or BRAF V600E mutations, which may affect treatment response. Participants receive treatment with study drugs such as pumitamig, bevacizumab, and chemotherapy regimens including FOLFOX, FOLFIRI, and CAPOX. The treatments are given at specified doses on specific days. The study uses a randomized, double-blind design with multiple experimental and comparator arms to assess these combinations. Throughout the study, participants undergo regular assessments to measure tumor response and survival outcomes. Key evaluations include imaging tests using RECIST v1.1 criteria, monitored by both investigators and independent reviewers, over a period of up to 5 years. Researchers track objective response, progression-free survival, and overall survival to determine treatment outcomes and safety.
