简要总结
Narcolepsy is a sleep disorder in which patients are not able to maintain wakefulness or require treatment to maintain wakefulness during the daytime. Narcolepsy is a lifelong neurologic disease for which no cure has been clinically available. JZP441 is currently being developed for the treatment of narcolepsy type 1 (NT1). This study will assess the safety of efficacy of JZP441 in adult patients with NT1.
详细描述
This Phase 1b, randomized, double-blind, sponsor-unblinded, placebo-controlled 4-way crossover study will evaluate the efficacy, safety, tolerability, and pharmacokinetics (PK) of a range of JZP441 doses in participants with NT1. Changes in daytime sleepiness will be assessed via objective (MWT) and subjective (KSS, VAS for sleepiness) efficacy measures.

结局指标
主要结局
Mean sleep latency of the first 4 sessions of the Maintenance of Wakefulness Test
时间窗: 1, 3, 5, and 7 hours after the first dose of study intervention
The MWT is the standard objective measure of an individual's ability to remain awake during the daytime in a darkened quiet environment and is commonly used to assess response to treatment. The MWT will be used to compare the pharmacodynamic response of JZP441 versus placebo. Sleep latency will be reported in minutes.

- Number of Participants Reporting Treatment-emergent Adverse Events(Baseline up to Week 11)
- Pharmacokinetic Parameter Maximum Plasma Concentration(Day 1 (predose), 2, 4, 6, 8, 10, and 12 hours post first dose; Day 2 (24 hours) post first dose.)
