- Milestone marks the first patient with GM1 gangliosidosis treated with gene therapy
- Initial data expected in second half of 2019
- AXO-AAV-GM1 is Axovant’s third investigational gene therapy program to enter the clinic
BASEL, Switzerland, May 16, 2019 (GLOBE NEWSWIRE) – Axovant Gene Therapies Ltd. (Nasdaq: AXGT), a clinical-stage company developing innovative gene therapies, today announced dosing of the first patient in a clinical study of AXO-AAV-GM1 (also known as AAV9-GLB1), an investigational gene therapy for the treatment of GM1 gangliosidosis. To date, the patient experienced no complications related to the intravenous (IV) administration of the vector and continues to be followed by physicians. GM1 gangliosidosis is a progressive and fatal pediatric lysosomal storage disorder caused by mutations in the GLB1 gene leading to impaired production of the beta-galactosidase enzyme. There are currently no approved treatments for GM1 gangliosidosis. Axovant expects initial data from the AXO-AAV-GM1 clinical program in the second half of 2019, as well as continued enrollment of patients in this program throughout 2019.
The clinical study of AXO-AAV-GM1 is being conducted at the National Institutes of Health (NIH), by Cynthia Tifft, M.D., Ph.D., Deputy Clinical Director at the National Human Genome Research Institute, and a leading expert in ganglioside storage disorders. A three-way Cooperative Research and Development Agreement (CRADA) between Axovant, the NIH, and the University of Massachusetts (UMass) Medical School has been established to support the conduct of the clinical program.
“GM1 gangliosidosis is a devastating disease in young children, for which there are no currently approved treatment options. The development of a safe and effective gene therapy for these patients would be a welcome advancement in the field of pediatric lysosomal storage disorders affecting the brain,” said Dr. Tifft.
The endpoints of the clinical study include safety, biomarker, neurodevelopment, and Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopy (MRS) measures.
AXO-AAV-GM1 delivers a functional copy of the GLB1 gene via an adeno-associated viral (AAV) vector, with the goal of restoring β-galactosidase enzyme activity for the treatment of GM1 gangliosidosis. The gene therapy is delivered intravenously, which has the potential to broadly transduce the central nervous system and treat peripheral manifestations of the disease as well. Preclinical studies in murine and a naturally-occurring feline model of GM1 gangliosidosis have supported AXO-AAV-GM1’s ability to improve β-galactosidase enzyme activity, reduce GM1 ganglioside accumulation, improve neuromuscular function, and extend survival.About Axovant Gene TherapiesAxovant, part of the Roivant family of companies, is a clinical-stage gene therapy company focused on developing a pipeline of innovative product candidates for debilitating neurological and neuromuscular diseases.
