Trial of Hu5F9-G4 in Combination With Cetuximab in Patients With Solid Tumors and Advanced Colorectal Cancer

Status: Active

Description

This trial will evaluate Hu5F9-G4 in combination with cetuximab. Hu5F9-G4 is a monoclonal antibody which is designed to block a protein called CD47, which is widely expressed on human cancer cells. Blocking CD47 with Hu5F9-G4 may enable the body's immune system to find and destroy the cancer cells. Cetuximab is a monoclonal antibody drug that is used for treatment of certain types of colorectal cancer as well as head and neck cancer. The major aims of the study are: (Phase 1b) to define the safety profile and to determine a recommended Phase 2 dose for Hu5F9-G4 in combination with cetuximab, and (Phase 2) to evaluate the objective response rate of Hu5F9-G4 in combination with cetuximab in patients with advanced colorectal cancer.
