Opexa Executes Service Agreement with Blood Group Alliance, Inc.

Further Enhancing Tovaxin Production Process in Support of Future Clinical Trials

THE WOODLANDS, Texas--(BUSINESS WIRE)-- Opexa Therapeutics, Inc. (NASDAQ: OPXA), a company developing Tovaxin®, a novel T-cell therapy for multiple sclerosis (MS), announced today that the Company has executed an agreement with Blood Group Alliance, Inc. (BGA), a cooperative of community blood centers, to provide blood collection services to support Opexa’s clinical studies, including a planned Phase III study of Tovaxin in patients with Relapsing-Remitting MS.

This agreement will substantially enhance the overall process for the production of Tovaxin as the first step in the manufacturing process is obtaining a unit of whole blood from the patient. With BGA’s North American footprint extending throughout the United States and into Canada, patients in Opexa’s clinical trials will have access to a very broad network of treatment centers ensuring improved efficiency in blood collection. BGA has agreed to manage the collection of the blood and ship the units to Opexa’s facility for further manufacturing of the Tovaxin product. Opexa recently announced a similar agreement with the American Red Cross. In combination, these two groups provide Opexa with access to over 90% of the blood procurement centers in the United States. With these agreements, Opexa has now put into place a strong network of procurement locations nationwide which provide feasibility for commercialization as well as an excellent supply chain for Opexa’s future clinical studies.

"The feasibility of procurement for the clinical manufacture of Tovaxin has been solidified with the execution of these agreements,” commented Jaye Thompson, Ph.D., Senior Vice President, Clinical Development and Regulatory Affairs of Opexa. “We are pleased to be associated with BGA and their network of community blood centers. Our partnership will allow Opexa great flexibility to utilize investigational sites in almost any location for future Tovaxin studies. This unlimited access will be valuable for our patients and physicians. In addition, these contracts should result in a stable and reduced cost of goods in the manufacture of Tovaxin.”

Charles Mosher, President and CEO, Blood Group Alliance, commented, “We have purposefully been reaching out to provide services to the cell therapy industry since 2005. Our goal is to provide the industry and our cooperative members the opportunity to collaborate in a mutually beneficial way to support patient needs. BGA is pleased to support the planned Phase III clinical trial of Tovaxin, a novel therapy that may positively impact the lives of patients with a chronic disease that poses risk of debilitation. We look forward to working together during Opexa’s Phase III study and through commercialization.”

About Opexa

Opexa Therapeutics, Inc. is dedicated to the development of patient-specific cellular therapies for the treatment of autoimmune diseases. The Company’s leading therapy, Tovaxin®, is a personalized cellular immunotherapy treatment that is in late stage clinical development for MS. Tovaxin is derived from T-cells isolated from 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 and, thereby, reduces the risk of relapse over time.

Opexa is preparing for a Phase III clinical trial with Tovaxin following the completion of a Phase IIb clinical study in 150 patients with MS. Data from this clinical study show evidence that relapsing-remitting MS patients treated with Tovaxin saw overall clinical and disability benefits over the placebo group, including a clinically relevant decrease in the Annualized Relapse Rate (ARR), and improvement in disability score (EDSS), as well as an excellent safety profile with no serious adverse events related to Tovaxin treatment.
