AN3025 was generated through rabbit immunization followed by phage display, then humanized by CDRs grafting. The binding affinity and specificity were studied by ELISA and FACS. The ability of AN3025 to mitigate TNF/TNFR2 signaling pathway was characterized using TNFR2 overexpressing Jurkat cell line in vitro. The in vivo anti-tumor activity was evaluated in TNFR2 humanized mouse model bearing MC38 tumor. Our early pre-clinical data demonstrate that AN3025 binds human TNFR2 with high affinity and blocks its interaction with TNFα, which enhances IFNγ production in Treg/Teff co-culture assay and significantly inhibits MC38 tumor growth as a monotherapy in the hTNFR2 mouse model.

“The anti-hTNFR2 antibody program (AN3025) has demonstrated great potentials in controlling tumors pre-clinically,” said Dr. Nanhai He, Head of Drug Discovery of Adlai Nortye. “We’ll continue to push this exciting program forward and are looking forward to its clinical development soon.”

About AN3025

AN3025 is a novel humanized IgG1 (variant) anti-hTNFR2 antibody that is currently under pre-clinical development. This antibody binds to the extracellular domain of human TNFR2 with sub-nanomolar affinity and occludes its ligand TNFa from accessing TNFR2. Since TNFR2 is highly expressed on a subset of immunosuppressive cells, including regulatory T cells (Tregs) and MDSCs, within tumor microenvironment, AN3025 is expected to amplify the antitumor immune response to aid in immunotherapy.
