PTC presents Sephience data at metabolic disorders symposium
PTC Therapeutics (PTCT) presented data on Sephience at a metabolic disorders symposium. Clinical trials and real-world data showed significant reductions in blood phenylalanine levels and dietary liberalization in PKU patients. Sephience is approved in the U.S., EU, and Japan. The drug carries warnings about bleeding risk and hypophenylalaninemia. PKU affects about 58,000 people globally.
