A 4-Week Study of the Safety, Efficacy, and Pharmacokinetics of JZP-110 [(R)-2-amino-3-phenylpropylcarbamate Hydrochloride] in Subjects With Parkinson's Disease and Excessive Sleepiness

Overview

  • Study type

    Interventional
  • Study phase

    II
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

This study is a 4-week, multicenter, randomized, double-blind, placebo-controlled, ascending dose, 4-period crossover study designed to evaluate the safety, tolerability, efficacy, and PK of JZP-110 (75, 150, and 300 mg) in the treatment of excessive sleepiness in adult subjects with idiopathic PD.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

See eligibility criteria

Inclusion Criteria:

  1. Diagnosis of idiopathic PD according to the UK PDS Brain Bank Criteria.
  2. Hoehn and Yahr stage 1, 2, or 3.
  3. Baseline ESS score >10.
  4. Baseline mean sleep latency of ≤20 minutes on the MWT.

Exclusion Criteria:

  1. Diagnosis of other degenerative Parkinsonian syndromes (e.g., progressive supranuclear palsy, multiple system atrophy [MSA], or dementia with Lewy bodies [DLB]).
  2. Usual nightly time in bed of <6 hours, including the night before the Baseline visit.
  3. Prior or documented history of moderate or severe obstructive sleep apnea (OSA).
  4. Has evidence at screening of severe cognitive impairment or has cognitive impairment that in the opinion of the investigator would prevent completion of study procedures or the ability to provide informed consent.
