About IGM-8444

IGM-8444 is an IgM antibody targeting Death Receptor 5 (DR5) that is being developed for the treatment of patients with solid and hematologic malignancies. DR5 is a member of the tumor necrosis factor receptor superfamily (TNFrSF) and is often expressed on the surface of cancer cells. Strong activation of the DR5 pathway requires multiple receptors to be cross-linked simultaneously by an antibody or other binding agent to create an apoptotic death signal to the cell. Unlike traditional IgG antibodies, IGM-8444 has 10 binding units, enabling it to cross-link multiple DR5 receptors at the same time, sending a stronger signal to cause cancer cell death. The Company is currently conducting a multicenter, open-label clinical trial to determine the safety, tolerability, and pharmacokinetics of IGM-8444 as a single agent and in combination in subjects with relapsed and/or refractory solid or hematologic cancers.
