A Multiple Ascending Dose Study to Investigate the Safety, Tolerability, and Pharmacokinetics of JZP441 in Healthy Participants

Completed · Phase 1 · Has a placebo group

Conditions studied: Healthy Participants

In brief

Treatments for narcolepsy and hypersomnolence disorders should have good oral bioavailability and brain penetration properties. JZP441 has demonstrated wake-promoting efficacy and anticataplectic activity in nonclinical studies and may represent a novel approach for these patients.
