Abeona Therapeutics and Taysha Gene Therapies Enter into Licensing and Inventory Purchase Agreements for ABO-202, a Clinical Stage, Novel, One-time Gene Therapy for CLN1 Disease - Seite 2

ABO-202 is a one-time, self-complementary AAV (serotype 9) gene therapy designed to deliver a functional copy of the palmitoyl-protein thioesterase 1 (PPT1) gene. Preclinical studies in a CLN1 animal model demonstrated that ABO-202 normalized survival and led to improvement of neurological function in affected mice.  The therapy has been granted Orphan Drug and Rare Pediatric Disease designations by the U.S. Food and Drug Administration (FDA) and has received Orphan Medicinal Product Designation from the European Medicines Agency.

About CLN1 disease (Infantile Batten disease)
CLN1 disease, also known as Infantile Neuronal Ceroid Lipofuscinosis or infantile Batten disease, is a rapidly progressing rare lysosomal storage disease with no approved treatment. It primarily affects the central nervous system and typically manifests during the first year of life with vision impairment that can progress to blindness, progressive motor and cognitive decline, seizures and ultimately early death. The underlying cause of the disorder is a defect in the PPT1 gene that encodes the enzyme of the same name, resulting in the accumulation of lipopigments within cells, leading to neuroinflammation and neurodegeneration. Some patients with CLN1 disease develop symptoms later in childhood or in adulthood; these variants are called late-infantile, juvenile, or adult-onset CLN1.

About ABO-202
ABO-202 is a novel, one-time gene therapy for CLN1 disease, a rapidly progressing rare lysosomal storage disease with no approved therapy. ABO-202 delivers a functional copy of the PPT1 gene to address the underlying gene and enzyme deficiency that leads to abnormal buildup of lipopigments and results in neuroinflammation and neurodegeneration.

About Abeona Therapeutics
Abeona Therapeutics Inc. is a clinical-stage biopharmaceutical company developing gene and cell therapies for serious diseases. Abeona’s clinical programs include EB-101, its autologous, gene-corrected cell therapy for recessive dystrophic epidermolysis bullosa in Phase 3 development, as well as ABO-102 and ABO-101, novel AAV-based gene therapies for Sanfilippo syndrome types A and B (MPS IIIA and MPS IIIB), respectively, in Phase 1/2 development. The Company’s portfolio of AAV-based gene therapies also features ABO-201 for CLN3 disease. Abeona’s novel, next-generation AIM capsids have shown potential to improve tropism profiles for a variety of devastating diseases. Abeona’s fully functional, gene and cell therapy GMP manufacturing facility produces EB-101 for the pivotal Phase 3 VIITAL study and is capable of clinical and commercial production of AAV-based gene therapies.
