NEW YORK and CLEVELAND, Jan. 19, 2017 (GLOBE NEWSWIRE) —
- ABO-101, Abeona’s third AAV gene therapy program to receive EMA Orphan Designation
- Clinical trials anticipated to begin enrolling in second quarter 2017
- Natural History Study in 25 patients has established efficacy outcome measures
- FDA previously granted Orphan Drug and Rare Pediatric Disease Designations
Abeona Therapeutics Inc. (Nasdaq:ABEO), a clinical-stage biopharmaceutical company focused on developing gene therapies for life-threatening rare diseases, announced today that the European Medicines Agency (EMA) Committee for Orphan Medicinal Products has granted Orphan Drug Designation (EMA/OD/226/16) for Abeona’s gene therapy program ABO-101 for children impacted by Sanfilippo syndrome type B (MPS IIIB), a rare autosomal recessive disease that causes neurocognitive decline, speech loss, loss of mobility, and premature death in children.
“This designation builds on our commercial portfolio of AAV gene therapies that have received FDA and EMA orphan drug designations, which is an important validation of the scientific and clinical translation of these products for severely underserved patient populations,” stated Timothy J. Miller, Ph.D., President & CEO of Abeona Therapeutics Inc. “Accomplishing the designation would not have been possible without the contributions of Nationwide Children’s Hospital researchers Drs. Doug McCarty and Haiyan Fu, the Stop Sanfilippo Fundacion, Fundacion Sanfilippo B, Red Sanfilippo Fundacion, the Sanfilippo Children’s Research Foundation, Ben’s Dream, the Sanfilippo Medical Research Foundation, Team Sanfilippo and the National MPS Society USA.”
ABO-101 has previously been granted the U.S. Food and Drug Administration (FDA) Orphan Product Designation in the United States and received the Rare Pediatric Disease Designation as a pre-requisite part of the FDA’s Priority Review Voucher (PRV) process. The FDA has allowed the Investigational New Drug (IND) for a Phase 1/2 clinical trial, and enrollments are anticipated to begin in the second quarter of 2017.
About European Union (EU) Orphan Drug Designation: The European Commission grants orphan drug designation status to provide incentives to develop medicinal products to treat, prevent or diagnose diseases or conditions that affect no more than five in 10,000 persons in the European Union. The orphan drug designation provides Abeona with incentives and benefits in the EU, including protocol assistance, reduced fees and protection from market competition once ABO-101 is approved for the treatment of MPS IIIB patients.
About ABO-101 (AAV-NAGLU): ABO-101, the company’s first-in-human, adeno-associated viral (AAV)-based gene therapy for MPS III (Sanfilippo syndrome), which involves a one-time intravenous delivery of a normal copy of the Naglu gene to cells of the central nervous system and peripheral organs with the aim of reversing the effects of the genetic errors that cause the disease. After a single dose of ABO-101 in Sanfilippo preclinical models, ABO-101 induced cells in the CNS and peripheral organs to produce the missing enzyme and remove the underlying sugar (GAG) storage pathology in cells. Preclinical in vivo efficacy studies in Sanfilippo syndrome have demonstrated functional benefits that remain for months after treatment. A single dose of ABO-101 significantly restored normal cell and organ function, corrected cognitive defects that remained months after drug administration, increased neuromuscular function and normalized the lifespan of animals with MPS IIIB after treatment compared to untreated control animals. These results are consistent with studies from several laboratories suggesting AAV treatment could potentially benefit patients with Sanfilippo syndrome. Safety and efficacy studies of AAV gene therapy treatments for Sanfilippo syndrome have recently been published in several peer-reviewed scientific journals.
About Sanfilippo syndromes (or mucopolysaccharidosis): Mucopolysaccharidosis (MPS) type III (Sanfilippo syndrome) is a group of four inherited genetic diseases each caused by a single gene defect, described as type A, B, C or D, which cause enzyme deficiencies that result in the abnormal accumulation of glycosaminoglycans (GAGs, or sugars) in body tissues. MPS III is a lysosomal storage disease, a group of rare inborn errors of metabolism resulting from deficiency in normal lysosomal function. Mucopolysaccharides (GAGs) are long chains of sugar molecules used in building connective tissues in the body. There is a continuous process in the body of replacing used materials and breaking them down for disposal. Children with MPS III are missing an enzyme, which is essential in breaking down the used mucopolysaccharides called heparan sulfate. The partially broken down mucopolysaccharides remain stored in cells in the body causing progressive damage. In MPS III, the predominant symptoms occur due to accumulation of GAGs within the central nervous system (CNS), including the brain and spinal cord, and other tissues, which result in cognitive decline, motor dysfunction, and eventual death. Importantly, there is no cure for MPS III and treatments are largely supportive care.
About Abeona: Abeona Therapeutics Inc. is a clinical-stage biopharmaceutical company developing gene therapies for life-threatening rare genetic diseases. Abeona’s lead programs include ABO-102 (AAV-SGSH) and ABO-101 (AAV-NAGLU), adeno-associated virus (AAV) based gene therapies for Sanfilippo syndrome (MPS IIIA and IIIB, respectively). Abeona is also developing EB-101 (gene-corrected skin grafts) for recessive dystrophic epidermolysis bullosa (RDEB), EB-201 for epidermolysis bullosa (EB), ABO-201 (AAV-CLN3) gene therapy for juvenile Batten disease (JNCL), ABO-202 (AAV-CLN1) gene therapy for treatment of infantile Batten disease (INCL), and ABO-301 (AAV-FANCC) for Fanconi anemia (FA) disorder and ABO-302 using a novel CRISPR/Cas9-based gene editing approach to gene therapy for rare blood diseases. In addition, Abeona has a plasma-based protein therapy pipeline, including SDF Alpha™ (alpha-1 protease inhibitor) for inherited COPD, using its proprietary SDF™ (Salt Diafiltration) ethanol-free process.
