Sells medicines for PKU, DMD, AADC deficiency, and other rare disorders across the United States and international markets, while developing RNA-splicing and inflammation programs. Revenue combines product sales with collaboration and royalty income, with regulatory approvals, reimbursement, and partners shaping the business.
Develops and commercializes medicines for rare neurological and metabolic disorders. The marketed portfolio spans Sephience for phenylketonuria, Translarna and Emflaza for Duchenne muscular dystrophy, Upstaza/Kebilidi gene therapy for AADC deficiency, and Latin American rights to Tegsedi and Waylivra. Sales reach the United States, Europe, Japan, Latin America, and other international markets.
Builds candidates through RNA-splicing and inflammation-and-ferroptosis platforms. Votoplam for Huntington’s disease is being advanced in a Novartis-funded late-stage study, supporting collaboration economics, while earlier programs target neurological, hematologic, and inflammatory diseases.
Commercial execution pairs global launches with country-level pricing and reimbursement work. Operations are managed as a single segment and depend on product authorizations, external manufacturers and distributors, and collaborators that develop or commercialize partnered assets.
