Early Phase 1RecruitingCity of Hope Medical CenterNCT05245786Data as of May 2026

Treatment: Copper Cu 64 Anti-CEA Monoclonal Antibody M5AThis early phase I trial investigates how well 64Cu-labeled M5A antibody scan works in assessing tumor activity before and after patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced) who are undergoing chemotherapy and radiotherapy. Using 64Cu-labeled M5A positron emission tomography imaging may play a significant role in imaging patients with colorectal cancer.
