October 27, 2023 I JCR Pharmaceuticals Co., Ltd. (TSE 4552; Chairman and President: Shin Ashida; “JCR”) announced today that the first patient in the Phase I/II clinical trial withMucopolysaccharidosis Type IIIA (MPS IIIA; Sanfilippo Syndrome Type A) has been dosed with JR 441, a blood brain barrier (BBB) penetrating form of heparan N sulfatase that was developed using JCR’s proprietary J Brain Cargo ® BBB penetrating technology. JR 441 is a recombinant fusion protein of antibody fragment against the human transferrin receptor and heparan N sulfatase, the enzyme missing or malfunctioning in subjects with MPS IIIA .
MPS IIIA is a lysosomal storage disorder (LSD) characterized by multiple somatic and neurological signs and symptoms with no established standard of care. While MPS III is a heterogeneous disease, type IIIA is typically characterized by an earlier onset than other forms of MPS III. While less prevalent in Japan, MPS IIIA is considered to be the most prevalent form of MPS III globally. Preclinical evidence indicated that JR-441 may address the somatic as well as neurological sequalae of MPS IIIA in individuals affected with the disease. JR-441 was received orphan drug designation by the European Commission (EC) in January 2022.
The main objectives of the phase I/II clinical study which is conducted at the International Center for Lysosomal Disorders (ICLD) of the University Hospital of Hamburg Eppendorf (UKE) is to establish the safety of chronic dosing of JR 441 in individuals with MPS IIIA, the pharmacokinetics of JR 441 and to explore early signs of efficacy. Th e trial is an open label study comparing two different doses of JR 441 over a treatment period of 52 weeks. Patients participating in the trial will be offered to enter an extension study upon completion of the treatment period.
“Offering patients a treatment option with an innovative therapy that is designed to address both somatic and central nervous system signs and symptoms of MPS IIIA completely changes my conversations with families having an affected member with MPS IIIA. This disease has no established standard of care and enrollment in this study offers them access to an experimental interventional tre atment” said PD Dr. Nicole Muschol, Principal Investigator of t he trial.“
JR 441 is the third program based on the J Brain Cargo ® platform that enters clinical stage, following JR 141 and JR 171 ,,” adds Shin Ashida, Chairman, President and CEO of JCR Pharmaceuticals, “it is another testament to our efforts to bring our innovation to patients across the globe. My deepest respect goes to the families, Dr. Muschol and all the physicians and clinical staff who are so committed to changing the future of individuals affected with this disease.”
The trial is a single center study in Germany and intends to enroll a total of twelve patients , age one to 18 years at various stages of disease progression. Further information can be found at clinicaltrials.gov under the NCT identifier NCT06095388.
JCR, a pharmaceutical company having developed the proprietary BBB penetrating technology J Brain Cargo ® , is focusing on the development of treatments for LSDs with central nervous system signs and symptoms. JCR intends to start clinical trials on four additional programs from its LSD pipeline by FY2027 .
There is no impact on the consolidated business results for this fiscal year ending on March 31, 2024 related to the matter.
About Sanfilippo syndrome (MPS III)
Sanfilippo syndrome is an autosomal recessive disease caused by a deficiency of the enzymes that metabolize mucopolysaccharides within the body. The disease is classified into four subtypes (A, B, C, and D) according to the respective deficient enzymes. Sy mptoms include accumulation of heparan sulfate in tissues throughout the body. Notably, the rapidly progressive form of the disease frequently affects neurocognitive development, which peaks around 2 or 3 years of age, before subsequent ly deteriorati ng, re sulting in a complete loss of speech by the age of 7 or 8. Progression further gives rise to symptoms such as sleep disorders, hepatosplenomegaly, seizures , and neurobehavioral abnormalities.
