About this study

Official title: A 4-Week, Double-blind, Placebo-controlled, Randomized, Multicenter, Crossover 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

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs) Leading to Early Discontinuation

    Measured: Up to Day 35

Secondary outcomes (1)
  1. Change From Baseline in Epworth Sleepiness Scale (ESS) Total Score

    Change from Baseline ESS defined in terms of change from study baseline (prior to first dose in Period 1) to the end of each Treatment Period (Weeks 1, 2, 3, and 4).

    The Epworth Sleepiness Scale (ESS) is a self-administered questionnaire with 8 questions, asking subjects how likely they would be to doze off or fall asleep in different situations. Responses range from 0 = would never doze to 3 = high chance of dozing. Higher scores represent greater severity of excessive sleepiness. The total score ranges from 0 - 24, with higher scores representing greater severity of excessive sleepiness.

    Measured: Baseline to Weeks 1, 2, 3, and 4

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing JZP-110 in people with Excessive Sleepiness and Parkinson Disease, run by Jazz Pharmaceuticals at 25 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 25 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Jan 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment Emergent Adverse Events (TEAEs) Leading to Early Discontinuation (time frame: Up to Day 35). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03037203, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jan 2020.
