Long-Term Open-Label Study of ALKS 2680 Tablets for Narcolepsy Type 1, Type 2, and Idiopathic Hypersomnia

What this Trial Is About

Researchers are evaluating the long-term safety, tolerability, and lasting effects of ALKS 2680 tablets in adults with Narcolepsy Type 1, Narcolepsy Type 2, or Idiopathic Hypersomnia. This study is an open-label extension designed to continue monitoring participants who completed earlier ALKS 2680 parent studies, focusing on treatment durability and adverse events over an extended period. Participants receive ALKS 2680 oral tablets in doses ranging from 4 mg to 18 mg once daily. The study includes groups with Narcolepsy Type 1, Narcolepsy Type 2, and Idiopathic Hypersomnia. Treatment effects and safety are observed for up to 100 weeks, with dosing adjusted as needed. The study follows a non-randomized, open-label design without blinding. During the study, participants undergo regular assessments including monitoring of treatment-emergent adverse events, measurement of sleep latency using the Maintenance of Wakefulness Test, and evaluation of daytime sleepiness via the Epworth Sleepiness Scale. The total participation duration extends up to approximately 100 weeks, with safety, tolerability, and treatment effects closely tracked throughout this period.
