Overview

IMM01 + tislelizumab is an investigational combination immunotherapy being evaluated for the treatment of advanced solid tumors and classic Hodgkin lymphoma. IMM01 (timdarpacept) is a recombinant SIRPα-Fc fusion protein that targets the CD47-SIRPα pathway. It is designed with a dual mechanism of action: blocking the 'don't eat me' signal by disrupting the CD47/SIRPα interaction and delivering an 'eat me' signal through its IgG1 Fc domain, which engages activating Fcγ receptors on macrophages. Notably, IMM01 is engineered to avoid binding to human red blood cells, which minimizes the risk of treatment-induced anemia. Tislelizumab is a humanized IgG4 monoclonal antibody directed against the programmed cell death protein 1 (PD-1) receptor, acting as a checkpoint inhibitor to restore T-cell mediated anti-tumor responses. Together, the combination aims to synergistically activate both innate and adaptive immune responses against cancer cells.
