A Randomized, Controlled, Open-label, Multicenter, Phase IIb Safety and Efficacy Study of rhHNS (Recombinant Human Heparan N Sulfatase) Administration Via an Intrathecal Drug Delivery Device in Pediatric Patients With Early Stage Mucopolysaccharidosis Type IIIA Disease
In Brief
A Phase 2 clinical trial evaluating Recombinant human heparan N-sulfatase [rhHNS] for Sanfilippo Syndrome. Completed, enrolled 21 participants across 10 sites in 8 countries.
Detailed Summary
Sanfilippo syndrome Type A, or Mucopolysaccharidosis (MPS) IIIA, is a rare lysosomal storage disease caused by deficiency of the enzyme heparan N-sulfatase (sulfamidase). In the absence of this enzyme, there is an accumulation of the glycosaminoglycan, heparan sulfate, resulting in progressive neurodegeneration. Symptoms are usually first noted in the 1st or 2nd year of life, although definitive diagnosis is often delayed, with an average age of diagnosis of 4.5 years. The disease is characterized by developmental delays initially, followed by neurological developmental arrest, then regression. These developmental deficits are typically associated with severe behavioral disturbances. Patients have a significantly reduced lifespan, with few surviving beyond the 2nd or 3rd decade. The purpose of this study is to evaluate the safety and efficacy of recombinant human heparan-N-sulfatase (rhHNS) in pediatric patients with Early Stage Mucopolysaccharidosis Type III A Disease.
