Product Description
JR-446 is a novel drug developed based on the J-Brain Cargo technology, which has been clinically validated through the approval of IZCARGO for the treatment of MPS II in Japan in 2021. Animal studies have previously confirmed delivery of JR-446 into the Central Nervous System (CNS) and somatic organs and significant reduction of substrate caused by the deficiency in the enzyme that causative for the onset of MPS IIIB. As there is no established standard of care for the treatment of MPS IIIB, JR-446 is believed to have the potential to become a transformative treatment of MPS IIIB.
