First-In-Man Gene Therapy Delivering AAV by Single Intravenous Injection to Treat Central Nervous System and Peripheral Manifestations of Disease
NEW YORK, NY and CLEVELAND, OH -- (Marketwired) -- 05/17/16 --
Abeona Therapeutics Inc. (NASDAQ: ABEO), a clinical-stage biopharmaceutical company focused on developing products for severe and life-threatening rare genetic diseases, announced today that the first patient in a Phase 1/2 trial for ABO-102 (AAV-SGSH), a single treatment gene therapy strategy for patients with Sanfilippo syndrome type A (a.k.a Mucopolysaccharidosis Type IIIA or MPS IIIA) has been enrolled at Nationwide Children's Hospital (Columbus, Ohio).
"MPS IIIA is a profound and deadly lysosomal storage disease with no approved treatments available. Caused by a single gene defect, most of the children with this disease do not reach adulthood. This investigational gene therapy approach, delivered as a single intravenous injection to treat the whole body, represents a new treatment paradigm for addressing this relentlessly progressing disease," noted Kevin M. Flanigan, MD, 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. "We are grateful to the many patient foundations and parents who have supported the research needed to advance a potential treatment for this devastating unmet medical need."
"This treatment trial is the culmination of more than eighteen years of research and development, and none of it would have been possible without support from the Sanfilippo foundations," say Drs. Haiyan Fu and Doug McCarty, who lead the lysosomal disease basic research program in the Center for Gene Therapy.
The company previously announced that ABO-102 has been granted Orphan Product Designation in the USA and received the Rare Pediatric Disease Designation.
The clinical study is supported by neurocognitive testing data generated in a 25-subject MPS III Natural History Study, where all patients are through 1 year of follow up assessments.
"Abeona has demonstrated global leadership in supporting clinical and commercial development of promising gene therapies for children with Sanfilippo syndrome, and we applaud their efforts to bring these potential treatments to clinical trials," said Kathleen Buckley, President of Team Sanfilippo.
"This first-in-man gene therapy, which uses an AAV delivered by a single intravenous injection to treat the central nervous system and the peripheral disease manifestations in Sanfilippo patients, helps advance the field of gene therapy with new treatment options for these devastating diseases," noted Timothy J. Miller, PhD, Abeona's President and CEO.
About ABO-102 (AAV-SGSH): ABO-102 is an adeno-associated viral (AAV)-based gene therapy for MPS IIIA (Sanfilippo syndrome), which involves a one-time delivery of a normal copy of the defective gene to cells of the central nervous system (CNS) with the aim of reversing the effects of the genetic errors that cause the disease. After a single dose in Sanfilippo preclinical models, ABO-102 induced cells in the CNS and peripheral organs to produce the missing enzyme repaired the underlying cell pathology that is the cause of the disease. Preclinical in vivo efficacy studies in Sanfilippo syndrome have demonstrated functional benefits that are sustained for months to years after treatment. A single dose of ABO-102 significantly restored normal cell and organ function, corrected cognitive deficits, increased neuromuscular function and normalized the lifespan of animals with MPS IIIA over 100% for more than one year after treatment compared to untreated control animals. These results are consistent with studies from several laboratories suggesting AAV treatment to replace the defective gene could potentially benefit patients with Sanfilippo syndrome. In addition, safety studies conducted in animal models of Sanfilippo syndrome have demonstrated that delivery of ABO-102 is well tolerated with minimal side effects.
About Abeona: Abeona Therapeutics Inc. is a clinical stage company developing gene therapy and plasma-based products for severe and life-threatening rare genetic diseases. Abeona's lead programs are ABO-102 (AAV-SGSH) and ABO-101 (AAV-NAGLU), adeno-associated virus (AAV) based gene therapies for Sanfilippo syndrome (MPS IIIA and IIIB), respectively. We are also developing ABO-201 (AAV-CLN3) gene therapy for juvenile Batten disease (JBD); and ABO-301 (AAV-FANCC) for Fanconi anemia (FA) disorder using a novel CRISPR/Cas9-based gene editing approach to gene therapy program for rare blood diseases. In addition, Abeona is developing plasma protein therapies, including SDF Alpha™ (alpha-1 protease inhibitor) for inherited COPD, using our proprietary SDF™ (Salt Diafiltration) ethanol-free process.
