rAAV2/5-hNAGLU is an investigational gene therapy developed by uniQure N.V. for Sanfilippo Syndrome B, a rare inherited metabolic disorder. It is designed to deliver a functional copy of the human NAGLU gene using an AAV2/5 viral vector, with the goal of restoring the enzyme missing in affected patients.
rAAV2/5-hNAGLU is being studied for the treatment of Sanfilippo Syndrome B, also known as Mucopolysaccharidosis type IIIB, a rare lysosomal storage disorder. It is administered as an intracerebral gene therapy in children with the condition, aiming to address the underlying enzyme deficiency in the central nervous system.
rAAV2/5-hNAGLU is developed by uniQure N.V., a gene therapy company listed on Nasdaq under the ticker QURE. The company is conducting clinical development of this vector for Sanfilippo Syndrome B.
rAAV2/5-hNAGLU is in Phase 1 clinical development. The completed Phase 1 trial evaluated intracerebral gene therapy in children with Sanfilippo Syndrome B. The program remains investigational and has not been approved by the FDA or any regulatory authority.
rAAV2/5-hNAGLU has been evaluated in one completed Phase 1 trial, NCT03300453, titled Intracerebral Gene Therapy in Children With Sanfilippo Type B Syndrome. The trial enrolled 4 patients in France. No active trials of this vector are currently listed.
