Detaljeret beskrivelse

This first-in-human study is designed to characterize the safety, tolerability, pharmacokinetics (PK), and pharmacodynamic (PD) of JZP269, an orexin-2 receptor agonist, in healthy participants. The study will also assess the effect of food on JZP269 PK, characterize cerebrospinal fluid (CSF) exposure, and evaluate the wake-promoting PD effects using the Maintenance of Wakefulness Test (MWT) and Karolinska Sleepiness Scale (KSS) in sleep-deprived participants.

Mean Sleep Latency on the Maintenance of Wakefulness Test (MWT) in Sleep-deprived Participants
Tidsramme: Day 1 of dosing and monitoring period
The MWT measures a participant's ability to remain awake under quiet conditions during the day. Sleep latency is the time it takes for a participant to fall asleep while trying to remain awake during the MWT, and sleep onset is determined objectively by electroencephalography. The MWT calculates mean sleep latency as the average time to sleep onset. Shorter mean sleep latency indicates a greater difficulty maintaining wakefulness.
Day 1 of dosing and monitoring period
Mean Karolinska Sleepiness Scale (KSS) Score in Sleep-deprived Participants
Tidsramme: Day 1 of dosing and monitoring period
The KSS is a 9-point scale that measures subjective sleepiness during the preceding 10 minutes, ranging from 1 ("extremely alert") to 9 ("very sleepy, great effort to keep awake, fighting sleep"). Higher scores indicate greater sleepiness.
Day 1 of dosing and monitoring period
