A Phase 1b/2 Trial of the Anti-CD47 Antibody Hu5F9-G4 in Combination with Cetuximab in Patients with Solid Tumors and Advanced Colorectal Cancer
CD47 is overexpressed on cancer and cancer stem cells and prevents their elimination by phagocytic macrophages by delivering a potent "don't eat me" signal. Hu5F9-G4 is a humanized monoclonal antibody (mAb) that binds to CD47 and blocks its interaction with its receptor, thereby enabling phagocytosis of cancer cells. Anti-CD47 is highly synergistic in combination with other anti-cancer therapies including tumor-targeting mAbs such as cetuximab.
Single arm, non-randomised study.
