First enzyme replacement therapy that reaches both the body and the brain for Hunter syndrome. Supported by Phase 1/2 data published in NEJM. Also received Rare Pediatric Disease Priority Review Voucher. Market cap ~$3.1B (sub-$7B). Launch planned within weeks of approval via Denali Patient Services. Next catalyst: BIIB122/DNL151 (LRRK2 inhibitor for Parkinson's) in Phase 3 with Biogen.
