Description:
The primary objectives of this study are: (Phase 1b) to investigate the safety and
tolerability and to determine the recommended Phase 2 dose (RP2D) for magrolimab in
combination with cetuximab; and (Phase 2) to evaluate overall response rate (ORR) of
magrolimab in combination with cetuximab in participants with Kirsten rat sarcoma 2 viral
oncogene homolog (KRAS) mutant and KRAS wild-type colorectal cancer (CRC).

Purpose
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.
