U.S. Food and Drug Administration Accepts New Drug Application and Grants Priority Review for Takeda’s Oveporexton (TAK-861) as a Potential First-in-Class Therapy for Narcolepsy Type 1
-This FDA Acceptance is a Milestone for People Living with Narcolepsy Type 1 Who Need New and Different Treatment Options
-Oveporexton is an Orexin Agonist Designed to Restore Orexin Signaling and Address the Underlying Orexin Deficiency that Causes Narcolepsy Type 1
-The Prescription Drug User Fee Act (PDUFA) Target Action Date is the Third Quarter of this Calendar Year
OSAKA, Japan and CAMBRIDGE, Massachusetts, February 10, 2026 – Takeda (TSE:4502/NYSE:TAK) today announced that the U.S. Food and Drug Administration (FDA) accepted its New Drug Application (NDA) and granted Priority Review for oveporexton (TAK-861) for the treatment of narcolepsy type 1 (NT1). Oveporexton is an investigational oral orexin receptor 2 (OX2R)-selective agonist designed to address the underlying orexin deficiency that causes NT1 by restoring orexin signaling. The FDA has set a Prescription Drug User Fee Act (PDUFA) goal date in the third quarter of this calendar year. Takeda remains on track to potentially bring the first approved orexin agonist treatment to people living with NT1.
NT1 is a chronic, rare neurological disease caused by a loss of orexin and characterized by excessive daytime sleepiness and cataplexy (sudden loss of muscle tone). This results in a spectrum of physical, cognitive and psychosocial effects that can have a debilitating impact on many aspects of a person’s life, including work, education and social interactions. Despite existing therapies, the majority of patients continue to experience symptoms and are forced to cope with the continued impact of NT1.
“The FDA’s acceptance of our NDA is a milestone for people living with narcolepsy type 1,” said Andy Plump, M.D., Ph.D., president of R&D at Takeda. “Considering the high unmet need, this community deserves a new and different treatment approach that aims to address the underlying orexin deficiency that causes NT1 by restoring orexin signaling. We are one step closer to potentially transforming the current treatment paradigm and intend to deliver through our leading work in orexin science.”
The NDA filing is supported by a comprehensive data package including the FirstLight (TAK-861-3001) and RadiantLight (TAK-861-3002) global Phase 3 studies. Key oveporexton data measuring objective and patient-reported improvements in wakefulness, excessive daytime sleepiness, cataplexy, ability to maintain attention, overall quality of life and daily life functions demonstrate statistically significant and clinically meaningful improvements achieving near normal ranges across the broad range of symptoms investigated. Oveporexton was generally well-tolerated with a safety profile consistent across clinical studies to date. The most common adverse events were insomnia, urinary urgency and urinary frequency. Learn more about the Phase 3 data results here.
Oveporexton previously received Breakthrough Therapy designation for the treatment of excessive daytime sleepiness in NT1 from the U.S. FDA and the Center for Drug Evaluation of China’s National Medical Products Administration. Oveporexton has also received Sakigake designation from the Japanese Ministry of Health, Labour and Welfare.
The NDA filing has no significant impact on the full year consolidated forecast for the fiscal year ending March 31, 2026.
