About Opexa Opexa’s mission is to lead the field of Precision Immunotherapy™ by aligning the interests of patients, employees and shareholders. The Company’s leading therapy candidate, Tcelna ®, is a personalized T-cell immunotherapy currently in a Phase IIb clinical development program (the Abili-T trial) for the treatment of Secondary Progressive Multiple Sclerosis. Tcelna is derived from T-cells isolated from the patient’s peripheral blood, expanded ex vivo, and reintroduced into the patients via subcutaneous injections. This process triggers a potent immune response against specific subsets of autoreactive T-cells known to attack myelin. About Multiple Sclerosis (MS) Multiple Sclerosis is a chronic, inflammatory condition of the central nervous system and is the most common, non-traumatic, disabling neurological disease in young adults. It is estimated that approximately two million people have MS worldwide. While symptoms can vary, the most common symptoms of MS include blurred vision, numbness or tingling in the limbs and problems with strength and coordination. The relapsing forms of MS are the most common. The Secondary Progressive form of MS represents about a third of the MS patient population.
