BOSTON, Mass., May 6, 2026 -- Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) (Zevra, or the Company), a commercial-stage company focused on providing therapies for people living with rare disease, today reported its financial results for the first quarter ended March 31, 2026.

“We made meaningful progress across the business in the first quarter, led by continued performance for MIPLYFFA, underscoring its role in addressing the needs of patients with Niemann-Pick disease type C,” said Neil F. McFarlane, Zevra's President and Chief Executive Officer. “We also completed the $50.0 million divestiture of the SDX portfolio, and we repaid our term loan debt, sharpening our strategic focus and strengthening our financial position as we execute on our 2026 priorities.”

MIPLYFFA® (arimoclomol) Highlights

•U.S.: Received nine MIPLYFFA prescription enrollment forms for Niemann-Pick disease type C (NPC) during Q1 2026, bringing the total to 170 since product launch. Market access remains stable at 69% of covered lives.

•EU: A Marketing Authorisation Application for the evaluation of arimoclomol for the treatment of NPC is under review by the European Medicines Agency (EMA). The Company submitted its response to the EMA’s 120-day list of questions within the 90-day clock stop period, advancing the application along the standard review process. Arimoclomol has been designated an Orphan Medicinal Product by the EMA.

•Global Expanded Access Program (EAP): As of March 31, 2026, 122 patients were enrolled in the global EAP.

•In the Journal of Inherited Metabolic Disease, MIPLYFFA was included in the newly updated Clinical Practice Guidelines for the treatment and management of NPC.

Pipeline and Innovation Highlights

•Enrolled 10 patients in the event-driven Phase 3 DiSCOVER trial for the treatment of Vascular Ehlers-Danlos Syndrome during Q1 2026, bringing the total number of enrolled patients to 62, with a total of two confirmed events. The Company expects to hold a follow-up meeting with the Food and Drug Administration (FDA) in the second half of this year to explore pathways to accelerate clinical development.

Corporate Highlights

•Executed $50.0 million SDX portfolio sale to Commave Therapeutics, strengthening the balance sheet and supporting strategic priorities.

•Prepaid the principal balance on its $63.1 million term loan in full, resulting in a strong, debt-free balance sheet and enhanced financial and strategic flexibility.
