Opexa Therapeutics, Inc. (Opexa) is a biopharmaceutical company developing autologous cellular therapies with the potential to treat major illnesses, including multiple sclerosis (MS) and diabetes. The Company has a global license from Baylor College of Medicine (or Baylor) to an individualized T-cell therapeutic vaccine, Tovaxin, which is in clinical development for the treatment of MS. MS is the result of a person’s own T-cells attacking the myelin sheath that coats the nerve cells of the central nervous system (CNS). Tovaxin consists of attenuated patient-specific myelin reactive T-cells (MRTCs) against peptides from one or more of the primary proteins on the surface of the myelin sheath (myelin basic protein (MBP), proteolipid protein (PLP) and myelin oligodendrocyte glycoprotein (MOG)). Opexa has developed an adult stem cell technology to produce monocyte-derived stem cells (MDSC) from blood.
