The OX40/OX40L costimulatory pathway is crucial for effective T-cell activation and is inducibly expressed in response to immunological stimulation. Targeting OX40L has demonstrated safety and efficacy in preclinical studies using nonhuman primate models of kidney and heart transplantation.
APG-777 is an anti-IL-13 humanized monoclonal antibody (mAb) designed to block Th2 inflammatory signaling mediated by the IL-13Rα1/IL-4Rα complex, while APG-990 is a fully human anti-OX40L mAb that that blocks type 1/2/3 inflammatory signaling. Apogee Therapeutics Inc. is studying the combination effects of APG-777 and APG-990 as potential therapy for atopic dermatitis (AD).
