WAKIX (pitolisant) has received approval from Japan's Ministry of Health, Labour and Welfare for two key indications: excessive daytime sleepiness associated with obstructive sleep apnea syndrome (OSAS) for patients undergoing airway obstruction treatment, and narcolepsy (types 1 and 2). This marks the first approval in Japan for a histamine H3 receptor antagonist/inverse agonist targeting these specific sleep disorders.
Philippe Martin, Viatris Chief R&D Officer, highlighted that WAKIX offers a novel treatment option that is not classified as a controlled substance. The approval supports Viatris' strategy to grow its innovative medicines portfolio in Japan by addressing unmet medical needs with differentiated therapies. Excessive daytime sleepiness is a significant symptom for both OSAS and narcolepsy patients in Japan, impacting daily functioning and quality of life.
The regulatory submission was supported by data from domestic Phase 3 clinical trials in Japan, alongside international studies. WAKIX, a product licensed to Viatris for the Japanese market, was originally discovered by Bioprojet. It has prior approvals for narcolepsy in over 38 countries, including the U.S. and European nations, and for OSAS-related EDS in more than 29 European countries. The drug is designated as an orphan drug in Japan for narcolepsy.
