Abeona Therapeutics Receives FDA Fast Track Designation for ABO-101 for Treatment of Sanfilippo Syndrome Type B (MPS IIIB)
Ongoing Phase 1/2 study of ABO-101 enrolling eligible patients with MPS IIIB
NEW YORK and CLEVELAND, April 04, 2019 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (Nasdaq: ABEO), a fully-integrated leader in cell and gene therapy development, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to ABO-101, the Company’s novel one-time gene therapy for Sanfilippo syndrome type B (MPS IIIB). ABO-101 is designed to deliver a functional copy of the NAGLU gene to the central nervous system and peripheral tissues. Abeona is enrolling eligible patients with MPS IIIB at sites in the U.S. and Spain and expects to activate additional sites globally this year to accelerate enrollment. Information about the study is available at AbeonaTrials.com and ClinicalTrials.gov (NCT03315182).
“Receiving Fast Track designation is recognition by FDA that ABO-101 shows promise in treating a serious life-threatening disease and may address the significant unmet medical need of children with MPS IIIB,” said João Siffert, M.D., Chief Executive Officer. “We will continue to interact with global regulatory authorities about the ABO-101 clinical program to facilitate development of this one-time AAV9 mediated gene therapy.”
Fast Track designation is granted by the FDA to facilitate the development and expedite review of investigational therapies intended to treat serious or life-threatening diseases that show potential for addressing significant unmet medical needs. Clinical development of drug products receiving the designation benefit from frequent FDA interactions during all aspects of development and if specific criteria are met, they are eligible for priority review and accelerated approval. ABO-101 has also received Orphan Drug designations in the U.S. and EU, and Rare Pediatric Disease designation from the FDA.
ABO-101 is part of the Company’s portfolio of novel, one-time, AAV9-based gene therapies for rare lysosomal storage diseases. Pre-clinical data demonstrated that ABO-101 delivers a functional copy of the NAGLU gene to the central nervous system and peripheral tissues through a single intravenous infusion. The therapy is designed to address the underlying lysosomal enzyme deficiency responsible for abnormal accumulation of glycosaminoglycans in the brain and throughout the body that result in progressive cell damage and neurodevelopmental and physical decline.
About Sanfilippo Syndrome
Sanfilippo syndrome, or MPS type III, is a group of devastating rare genetic lysosomal storage diseases with no approved treatments. MPS III is characterized by developmental decline, including loss of ability to communicate, cognitive impairment, hearing loss, behavioral disturbances, seizures, as well as difficulties with sleep. Systemic manifestations include coarsening of facial features and enlargement of organs such as the liver. An estimated 70% of children with MPS III do not reach age 18. The underlying cause of the syndrome is a missing enzyme in the lysosome that is essential to breaking down heparan sulfate. As a result, partially degraded heparan sulfate accumulates inside the cells, including the brain and spinal cord, causing progressive damage. MPS III is caused by single gene defects unique to each type of the syndrome - A, B, C or D. The cause of MPS IIIA is a deficiency in the SGSH enzyme, while MPS IIIB is distinguished by a marked decrease in NAGLU enzyme activity.
About Abeona Therapeutics
Abeona Therapeutics Inc. is a clinical-stage biopharmaceutical company developing cell and gene therapies for life-threatening rare genetic diseases. The Company’s lead programs include EB-101, its gene-corrected cell therapy for recessive dystrophic epidermolysis bullosa, and ABO-102, a novel AAV9-based gene therapy for Sanfilippo syndrome type A (MPS IIIA). The Company’s portfolio of AAV9-based gene therapies also features ABO-101 for Sanfilippo syndrome type B (MPS IIIB), and ABO-202 and ABO-201 for CLN1 disease and CLN3 disease, respectively. Its preclinical assets include ABO-401, which uses the novel AIM™ AAV vector platform to address all mutations of cystic fibrosis. Abeona has received numerous regulatory designations from the FDA and EMA for its pipeline candidates and is the only company with Regenerative Medicine Advanced Therapy designation for two investigational therapies (EB-101 and ABO-102).
