Business Description

Overview We are a biotechnology company focused on identifying and advancing innovative therapeutic opportunities. In January 2026 we announced our wholly owned subsidiary, Axion Bio, Inc., or Axion Bio, was discontinuing development of our former lead product candidate, AXN-2510, a bispecific antibody targeting both programmed death-ligand 1 and the family of vascular endothelial growth factors in solid tumor cancers. Axion Bio in-licensed AXN-2510 from ImmuneOnco Biopharmaceuticals (Shanghai) Inc., or ImmuneOnco, in August 2024. The license and collaboration agreement with ImmuneOnco was terminated in January 2026. Prior to developing AXN-2510, our development efforts were focused on pursuing the development of cell therapies, including our proprietary folate receptor alpha co-stimulatory antigen receptor (CoStAR) tumor infiltrating lymphocyte (TIL) cell therapy for the treatment of cancer. We are actively seeking to in-license or acquire and develop additional novel therapeutic candidates in diseases with significant unmet medical need. Our Strategy Our strategy is to pursue potential acquisitions or in-licensing of therapeutic candidates.
