The clear emerging threat for Harmony Biosciences is the potential market entry of Axsome Therapeutics' AXS-12.

AXS-12 is an investigational drug for the treatment of narcolepsy, directly targeting the same indication as Harmony Biosciences' primary product, WAKIX (pitolisant). Axsome Therapeutics is currently conducting a Phase 3 trial (SYMPHONY) for AXS-12, with topline results expected in the second half of 2024. If successful, AXS-12 could offer a new treatment option for narcolepsy, potentially with a different efficacy or safety profile, which could compete directly for market share with WAKIX.

WAKIX® (pitolisant)

• U.S. Narcolepsy Therapeutics Market: The U.S. narcolepsy therapeutics market was valued at approximately $1.186 billion in 2023 and is projected to reach around $1.867 billion by 2030. Another estimate places the U.S. narcolepsy therapeutics market at $1.018 billion in 2024, growing to approximately $2.166 billion by 2034. The market opportunity for diagnosed narcolepsy patients in the U.S. is approximately 80,000 individuals.

• Global Idiopathic Hypersomnia Treatment Market: The global idiopathic hypersomnia treatment market reached $1.5 billion in 2024 and is expected to grow to $2.8 billion by 2031. North America holds a significant share, dominating the idiopathic hypersomnia treatment market with 50.5% in 2024.

• Sustained Market Penetration and Increased Patient Base for WAKIX in Narcolepsy: Harmony Biosciences continues to report strong demand and a growing patient base for its flagship product, WAKIX (pitolisant), for the treatment of narcolepsy. The company has consistently achieved record quarterly increases in the average number of patients on WAKIX, and management expects the drug to reach "blockbuster status," generating over $1 billion in annual revenue in narcolepsy alone.
• Launch of Next-Generation Pitolisant Formulations and Expansion into New Indications: Harmony Biosciences is advancing new formulations of pitolisant, including Pitolisant GR (gastro-resistant) and Pitolisant HD (high-dose/optimized pharmacokinetic profile). These next-generation formulations are designed to offer improved characteristics and extend the product's lifecycle, with patent protection for Pitolisant GR expected out to 2044. Additionally, the company is evaluating pitolisant for new indications, such as idiopathic hypersomnia, with Phase 3 trials for Pitolisant HD in this area expected to commence in Q4 2025.
• Advancement and Potential Commercialization of Novel Pipeline Assets: Harmony Biosciences is diversifying its pipeline beyond the current pitolisant franchise by developing new product candidates. A significant driver is BP1.15205, a highly potent and selective oral orexin-2 receptor agonist, which is an investigational compound for narcolepsy and other sleep/wake disorders. The first subject for BP1.15205 is expected to be dosed in Q4 2025. The company has also expanded its focus into rare epilepsies through strategic acquisitions, adding assets like EPX-100, which is in registrational Phase 3 trials. These new pipeline programs aim to address unmet medical needs in various neurological disorders and offer substantial future revenue potential.
