ADG106: Novel agonistic anti-CD137 NEObody™ candidate

Our NEObody™ candidate,ADG106, is a fully human ligand-blocking, agonistic anti-CD137 Immunoglobulin G4, or IgG4, mAb, being developed for the treatment of advanced solid tumors and non-Hodgkin’s lymphoma, or NHL. CD137 stimulates the immune system to attack cancer cells and is a key driver for long-lasting T-cell proliferation and survival. In preclinical studies, we observed that ADG106 had robust antitumor activity and was well tolerated as a single agent and in combination with the existing standard-of-care and other immuno-oncology therapies. ADG106 activates CD137 in a native ligand-like fashion, blocks reverse signaling of CD137 ligand, and has potent cross-linking via Fc receptor. Because of this novel mechanism of action, ADG106 was observed to favorably balance CD137-induced toxicity and CD137 agonism, which we believe has potential to address the limitations of other existing anti-CD137 therapies.

ADG106 is in ongoing Phase 1b/2a clinical trials in patients with advanced or metastatic solid tumors and/or relapsed/refractory non-Hodgkin’s lymphoma.
