HYOGO, Japan I October 31, 2024 I JCR Pharmaceuticals Co., Ltd. (TSE 4552; “JCR”) announced the initiation of the first patient dosing in Japan in the Phase I clinical trial of JR-441, an investigational enzyme replacement therapy for the treatment of mucopolysaccharidosis type IIIA (MPS IIIA, also known as Sanfilippo syndrome type A). JR-441 is a proprietary recombinant heparan N-sulfatase capable of crossing the blood-brain barrier (BBB).
MPS IIIA is a rare genetic disorder characterized by severe central nervous system (CNS) symptoms, for which there is currently no approved treatment. Preclinical studies have demonstrated the potential of JR-441 to address CNS-related symptoms associated with MPS IIIA.
This open-label, multicenter, single-arm study aims to assess the safety profile, biological effect, and pharmacokinetic profile of JR-441 in patients aged 1 to under 18 years with MPS IIIA.
“MPS IIIA has been one of the most significant challenges in the treatment of CNS symptoms,” said Dr. Kimitoshi Nakamura, Professor of Pediatrics at the Graduate School of Medical Sciences, Kumamoto University, and the Medical Expert of the study. “This novel therapeutic approach represents a new era for managing the condition. We have been eagerly awaiting the opportunity to offer this treatment, and I am hopeful that its effectiveness will be confirmed in the clinical setting, ultimately improving the daily lives of both patients and their families.”
JR-441 received Orphan Drug Designation from both the European Commission (EC) and the U.S. Food and Drug Administration (FDA), with a Phase I/II trial underway in Germany, which began in 2023 (JR-441-101, NCT06095388).

About Mucopolysaccharidosis Type IIIA (Sanfilippo Syndrome Type A)
Mucopolysaccharidosis type IIIA, or Sanfilippo syndrome type A, is an autosomal recessive disease caused by pathogenic mutations in the SGSH gene, encoding a lysosomal enzyme involved in the degradation of heparan sulfate. The accumulation of heparan sulfate in several types of cells of the body, especially in the central nervous system in the brain, results in severe neurological deterioration, cognitive impairment, mild somatic involvement, and shortened lifespan.
