Supernus receives seven‑year U.S. orphan‑drug exclusivity for ONAPGO and files sNDA for second supplier

Supernus announced that the FDA granted seven years of orphan‑drug market exclusivity for its ONAPGO apomorphine infusion device, effective February 3 2025. The company also submitted a supplemental New Drug Application for a second supplier of ONAPGO, with FDA approval expected by mid‑2027. The exclusivity and additional supplier aim to protect the product’s market position and address earlier supply constraints.

The exclusivity shields ONAPGO from generic competition for seven years, potentially supporting higher sales and margins for Supernus. The pending second‑supplier approval could improve supply reliability and sustain market demand.
