About MIPLYFFA
MIPLYFFA is Zevra’s only FDA-approved and commercialized therapy. It treats Niemann-Pick disease type C, a rare and serious brain disease that mostly affects children and has no other good options. The drug was granted FDA approval in 2024 in combination with miglustat.
By extending exclusivity to 2041, the new patent removes a major overhang on future cash flows, strengthens investor confidence in the company’s ability to generate durable profits from its lead asset, and supports Zevra’s broader pipeline and geographic-expansion plans.
In 2025, MIPLYFFA generated $87.4 million in net revenue, up from $10.1 million in 2024, and accounting for more than 82% of the company’s total net revenue of $106.5 million. The strong launch of MIPLYFFA drove Zevra from a net loss in 2024 to a full-year net profit of $83.2 million in 2025
