The release of extracellular vesicles (EVs) from microglia may play a key role in driving neurodegeneration in Sanfilippo syndrome. EVs are tiny particles that carry a variety of cargo, such as proteins and DNA, between cells to facilitate cell-to-cell communication. Microglia are a class of immune cells in the…

A Phase 1 clinical trial in Japan that’s testing JCR Pharmaceuticals‘ experimental enzyme replacement therapy JR-441 for treating Sanfilippo syndrome type A has dosed its first patient. The study will test the therapy as a once-weekly infusion into the bloodstream in children and adolescents, ages 1-18 to…

A number of proteins that accumulate to toxic levels in other neurodegenerative diseases also build up in cells derived from patients with all types of Sanfilippo syndrome, but treating the cells with a molecule to reduce heparan sulfate, which accumulates in Sanfilippo, also caused the other protein levels to…

JCR Pharmaceuticals said it received permission from the Pharmaceuticals and Medical Devices Agency (PMDA), a regulatory agency in Japan, to start a Phase 1 clinical trial of JR-441, an experimental enzyme replacement therapy for Sanfilippo syndrome type A.
