Regenxbio to File BLA for Hunter Syndrome Treatment
Regenxbio says it will file a BLA with FDA using the accelerated approval pathway for its RGX-121 to treat mucopolysaccharidosis type 2, also known as Hunter Syndrome. The company says its pivotal trial for RGX-121 is active and enrolling patients. Regenxbio describes RGX-121 as an investigational, one-time AAV (adeno-associated virus) therapeutic using the NAV AAV9 vector to deliver the gene that encodes the iduronate-2-sulfatase enzyme.
Company officials say their most recent discussions with FDA supported the plan to submit a BLA through the accelerated approval pathway.
