THE WOODLANDS, Texas--(BUSINESS WIRE)--Opexa Therapeutics, Inc. (NASDAQ:OPXA), a company developing Tcelna™, a novel T-cell therapy for multiple sclerosis (MS), today announced the initiation of a Phase IIb clinical trial of Tcelna in patients with Secondary Progressive Multiple Sclerosis (SPMS). Several patients have already been enrolled in the study and enrollment is expected to increase rapidly as additional sites begin screening and enrolling patients in the coming weeks. Tcelna is the first ever personalized T-cell therapy for MS patients and has received Fast Track Designation from the United States Food and Drug Administration (FDA) for the treatment of SPMS. The therapy is specifically tailored to each patient’s individual disease profile and has demonstrated superior safety and encouraging indications of efficacy in previous clinical studies in MS that included the treatment of SPMS patients. There is currently only one FDA-approved treatment for SPMS but safety warnings have severely restricted its use.
