CD137 (4-1BB) is a positive regulator of the immune system that is highly upregulated on activated T cells (adaptive immune cells) and NK cells (innate immune cells). The potential to dually target innate and adaptive immunity makes CD137 a highly attractive target for cancer immunotherapy. AGEN2373 is a fully human monoclonal antibody that boosts the immune response to cancer cells by enhancing CD137 co-stimulatory signaling in activated immune cells. Importantly, the unique binding properties of AGEN2373 are expected to limit its activity outside of the tumor site and mitigate toxicities that may be associated with systemic activation of CD137 in humans.
AGEN2373 is advancing in a clinical trial against solid tumors.
