FDA Approves Takeda’s Orzeyful for Narcolepsy Type 1
FDA has approved Takeda’s Orzeyful (oveporexton) tablets to treat narcolepsy type 1 in adults. An agency statement says Orzeyful is the first medicine approved for narcolepsy type 1 as a complete disorder, addressing the full range of symptoms that define the condition. It is the first drug to work by directly targeting the loss of orexin signaling that causes the disease, FDA says.
The statement says the safety and efficacy of Orzeyful were evaluated in two 12-week studies that enrolled 273 adults with narcolepsy type 1. It says that in both studies, patients taking Orzeyful 2 mg showed improvements in their ability to stay awake during the day compared with those receiving a placebo. Patients also reported substantially less daytime sleepiness, a significant reduction in cataplexy episodes, and meaningful improvement across the full range of narcolepsy symptoms, including sleep paralysis, hallucinations, and disrupted nighttime sleep.
The most common side effects were reported to be insomnia, increased urinary frequency, urgency to urinate, and increased saliva production.
FDA granted Orzeyful Breakthrough Therapy and Priority Review designations.
