About Bexion Pharmaceuticals

Bexion Pharmaceuticals, a mid-stage clinical stage biopharmaceutical company, is developing a new generation of biologic immunotherapy to treat solid tumor cancers and Chemotherapy Induced Peripheral Neuropathy (CIPN) with potential portfolio expansion opportunities in other cancers and broader neuropathic pain indications. Bexion’s lead drug candidate is BXQ-350, a first-in-class biologic containing the multifunctional, lysosomal activator protein, Saposin C and a-phosphatidylserine. BXQ-350, an “S1P Activator”, has demonstrated pre-clinical antitumor effects in vitro and in vivo, particularly in colorectal, brain and other solid tumors. Bexion has completed two single agent Phase 1 programs in adults and in a pediatric population. The Phase 1 programs demonstrated a strong safety profile with evidence of single agent activity across a range of solid tumors including Glioblastoma Multiforme (GBM), colorectal cancer and appendiceal cancer. Additionally, other clinical and non-clinical data suggest BXQ-350 improves symptoms associated with CIPN.
