NEW YORK and CLEVELAND, Feb. 17, 2017 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (Nasdaq:ABEO):
Abeona Therapeutics Inc. (NASDAQ:ABEO), a leading clinical-stage biopharmaceutical company focused on developing therapies for life-threatening rare genetic diseases, announced updated data from the ongoing gene therapy clinical trial for Sanfilippo syndrome Type A (MPS IIIA), at the 13th Annual WORLDSymposium™ 2017 lysosomal storage disorders conference in San Diego, CA. The ongoing Phase 1/2 trial for ABO-102 (AAV-SGSH) is a first-in-man clinical trial utilizing a single intravenous injection of AAV gene therapy for subjects with MPS IIIA, a rare autosomal recessive disease affecting every cell and organ in the body, which results in neurocognitive decline, speech loss, loss of mobility, and premature death in children.
“We remain encouraged by continued signs of tolerability and biopotency in the low-dose cohort, and enrollment of the high-dose cohort is underway,” stated Kevin M. Flanigan, M.D., principal investigator with the Center for Gene Therapy at Nationwide Children’s Hospital and Professor of Pediatrics and Neurology at The Ohio State University College of Medicine. “Additionally, we are pleased to see further decreases in CSF GAG measurements, as well as preliminary evidence for stabilization or improvement of some cognitive functions, at six months post-dosing.”
Per the design of the clinical trial, subjects received a single, intravenous injection of ABO-102 to deliver the AAV viral vector systematically throughout the body to introduce a corrective copy of the gene that underlies the cause of the MPS IIIA disease. Subjects are evaluated at multiple time points post-injection for safety assessments and initial signals of biopotency and clinical activity, which suggest that ABO-102 successfully reached target tissues throughout the body, including the central nervous system. Observations reported at the WORLDSymposium™ conference included:
“The data demonstrate an early and robust systemic delivery of ABO-102, and the increased reductions in CNS HS GAG support our approach for intravenous ABO-102 delivery for subjects with Sanfilippo syndromes,” stated Timothy J. Miller, Ph.D., President and CEO of Abeona Therapeutics. “We are excited about continued biomarker signals in this trial, as well as early positive signals in the neurocognitive assessments. While we are still very early in the trial, we are extremely encouraged by these early results and look forward to expanding enrollment in this clinical trial with enrollments accelerating at two additional international clinical sites.”
Abeona’s MPS IIIA program, ABO-102, has been granted Orphan Product Designation in the USA and in the European Union, has received the Rare Pediatric Disease Designation in the US, and recently received Fast Track designation by the US FDA.
Sanfilippo syndromes (or mucopolysaccharidosis (MPS) type III): 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. The incidence of MPS III (all four types combined) is estimated to be 1 in 70,000 births. Mucopolysaccharides are long chains of sugar molecule used in the building of 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 within the central nervous system (CNS), including the brain and spinal cord, resulting 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.
