• Two Phase 1/2 clinical trials for ABX-101 (MPS IIIB) and ABX-102 (MPS IIIA) for Sanfilippo Syndrome to commence in 2015

PlasmaTech Biopharmaceuticals, Inc. (NASDAQ: PTBI), a biopharmaceutical company advancing protein biologic therapies and oncology supportive care products, announced today that it has entered into a definitive agreement to acquire Abeona Therapeutics, a company engaged in the development and commercialization of therapies for patients with lysosomal storage diseases. Under the terms of the agreement, the Company will issue to Abeona Therapeutic members a total of 3,979,761 common shares upon closing of the transaction, and up to an additional $9 million in performance milestones, in common stock or cash, at the Company's option.

"We believe this acquisition represents an exciting cornerstone of our strategy to build a world class cell and gene therapy company focused on rare diseases," noted Steven H. Rouhandeh, PlasmaTech's Executive Chairman. "Abeona's programs in MPS IIIB & IIIA address a compelling unmet medical need with breakthrough technology and fundamental core competencies to develop products and accelerate value for patients and shareholders. This acquisition will accelerate development and internationalization of both clinical programs due to increased access to capital and organizational capabilities. Importantly, the Abeona operating and scientific teams will remain intact and we believe Tim Miller's unique blend of experience and capabilities makes him ideal to move the company forward towards our goal of becoming a leader in rare diseases.

Abeona Therapeutics is developing gene therapies for patients with rare genetic diseases, with initial therapies being developed for patients with Sanfilippo syndromes (MPS III). The Company was formed in early 2013 to help focus the search for a cure for Sanfilippo Syndrome and provide a unifying voice between patient advocate groups, researchers, clinicians and investors. Dr. Miller, a co-founder, has over 16 years of scientific research, product development, clinical operations and business development expertise, with a focus on transitioning novel biotherapeutics through pre-clinical development and into Phase 1 and 2 human clinical trials. Previously with Juventas Therapeutics, SironRX Therapeutics, and Copernicus Therapeutics, Dr. Miller has focused on gene therapy and regenerative medicine. During his career, he has worked on therapies in cystic fibrosis, cardiovascular disease, wound healing, scar prevention and Sanfilippo syndromes. Dr. Miller has managed all aspects of biotechnology business development, manufacturing of biologics, and multiple clinical programs from start-up and has direct experience engaging Food and Drug Administration (FDA) and NIH advisory agencies on multiple Investigational New Drug (IND) submissions.

"We want to thank our supporting foundations and patient advocates, who have demonstrated that their voice is a critical component of accelerating rare disease programs," said Dr. Miller. Abeona Investors include U.S.-based Cure Sanfilippo Foundation, Sanfilippo Research Foundation, Team Sanfilippo, the Abby Grace Foundation, the National MPS Society, The Children's Medical Research Foundation, Inc., and the Ryan Foundation. Abeona has strong international support from the international Sanfilippo community, with investments from Spain-based Stop Sanfilippo and Sanfilippo B Foundation, Geneva, Switzerland-based Fondation Sanfilippo, Australian-based Sanfilippo Children's Foundation and Mexico-based Red Sanfilippo Foundation. Support for the program has also been provided by the Canadian led Sanfilippo Children's Research Foundation (SCRF).

The Board of Directors of PlasmaTech Biopharmaceuticals and the Managers of Abeona have unanimously approved the transaction. The transaction is expected to close in the second quarter of 2015, subject to customary closing conditions.

About Alpha-1 Deficiency and SDF™ Process: The global market for drugs derived from human blood plasma fractionation is currently estimated to be greater than US$15 billion and growing at a rate close to 10% annually. Despite this significant market opportunity, limited innovation in fractionation technology has occurred in decades. PTBI has developed and patented a new extraction process for plasma biologics that may fundamentally change the economics of blood plasma fractionation, and is expected to make possible the extraction of several additional therapeutically useful plasma proteins. The Company believes that PlasmaTech's proprietary fractionation process is expected to significantly enhance yields of specific high-value proteins, including alpha-1 antitrypsin, expanding market opportunities while greatly enhancing margins. The Company believes that PlasmaTech's lead product opportunity, alpha-1 antitrypsin ("AAT"), will offer a potentially high revenue, short time-to-market respiratory product for treatment of inherited COPD, or alpha-1 antitrypsin deficiency ("AATD"), among other indications. In addition, the SDF process is expected to produce higher yields of other high-value proteins with significant therapeutic benefit.

About PlasmaTech: PlasmaTech is a biopharmaceutical company focused on advancing protein biologic therapies and oncology supportive care products. Exploiting two proprietary platforms, Salt Diafiltration (SDF™) Process and Polymer Hydrogel Technology (PHT™), PlasmaTech is active in the development and commercialization of human plasma-derived therapeutics, including its proprietary alpha-1 protease inhibitor, SDF Alpha™. The company has developed a robust product pipeline that includes two commercial stage products, MuGard® and ProctiGard™, with additional follow-on products in development.

About Abeona Therapeutics: Abeona was formed in early 2013 to help focus the search for a cure for Sanfilippo Syndrome and provide a unifying voice between patient advocate groups, researchers, clinicians and investors. Abeona Therapeutics is the result of collaborative efforts between scientists, clinicians and multiple international patient advocate groups for developing Sanfilippo therapies. The collaboration has helped focus parents and caregivers on a leading therapy with broad potential to provide long-term benefits to children with Sanfilippo Syndrome. Clinical trials for Sanfilippo types A and B are anticipated to begin in mid-2015.
