A phase 1/2 study of AU-007, a monoclonal antibody (mAb) that binds to IL-2 and inhibits CD25 binding, in patients with advanced solid tumors: Interim results.
Abstract:e14507 Background: AU-007 is a computationally designed mAb that binds to IL-2 on its CD25 binding epitope. AU-007 bound IL-2 (A/IL-2) cannot bind to trimeric (CD25, CD122, CD132) IL-2 receptors (IL-2R) on Tregs, vascular endothelium, or eosinophils, but IL-2’s binding to dimeric IL-2Rs (CD122, CD132) on T effector and NK cells is unhindered. AU-007 thus redirects endogenous or exogenous IL-2 (aldesleukin) towards T effector and NK cell activation, while diminishing immunosuppressive Treg activation and vascu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
