What is being measured

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

  1. Change in the Maintenance of Wakefulness Test (MWT)

    Change in the mean sleep latency time as determined from the first four trials of a 40-minute MWT from the end of the Stable Dose Phase to the end of the Double-blind Withdrawal Phase. Mean sleep latency defined as the average of the first four MWT trial's measurements.

    Measured: Week 4 to Week 6

  2. Change in the Epworth Sleepiness Scale (ESS)

    Change in Epworth Sleepiness Scale (ESS) score from the end of the Stable Dose Phase to the end of the Double-blind Withdrawal Phase. A negative change from baseline represents improvement in excessive sleepiness.

    The ESS is a self-administered questionnaire with 8 questions. Each activity is scored on a scale ranging from 0-3, with 0 = would never fall asleep, and 3 = high chance of falling asleep. The total score ranges from 0-24, with a higher number representing an increased propensity for sleepiness. An analysis of covariance (ANCOVA) was used for the analysis of ESS scores. The response variable was the change in ESS score from week 4 to week 6.

    Measured: Week 4 to Week 6

Secondary outcomes (3)
  1. Patient Global Impression of Change (PGIc)

    Percentage of subjects reported as worse (minimally, much, or very much) on the PGIc at the end of the Double-blind Withdrawal Phase. PGIc was rated by subjects and measures the change in their condition since treatment starts on a 7-point scale ranging from 1= very much improved to 7= very much worse.

    Measured: Week 4 to Week 6

  2. Clinical Global Impression of Change (CGIc)

    Percentage of subjects reported as worse (minimally, much, or very much) on the CGIc at the end of the Double-blind Withdrawal Phase. CGIc was rated by clinicians and measures the change in the subject's condition since treatment starts on a 7-point scale ranging from 1= very much improved to 7= very much worse.

    Measured: Week 4 to Week 6

  3. Change in Functional Outcomes of Sleep Questionnaire (FOSQ-10)

    Change is total score from the end of the stable dose phase to the end of the double blind withdrawal phase. Functional Outcomes of Sleep Questionnaire Short Version (FOSQ-10) is a 10-item disease-specific quality of life questionnaire to assess the effect of excessiveness sleepiness on multiple activities of everyday living. The FOSQ-10 consists of 10 questions, each scored on a scale from 1-4. The questionnaire has a 4-point response format for each question (1 = extreme difficulty, 2 = moderate difficulty, 3 = a little difficulty, and 4 = no difficulty). The total score is derived by the mean of the 5 subscale scores, multiplied by 5, resulting in a possible range of scores between 5 to 20; lower FOSQ-10 scores are worse, indicating more difficulty carrying out activities; higher FOSQ-10 scores are better, indicating less difficulty carrying out activities.

    Measured: Week 4 to Week 6

A Phase 3 study testing JZP-110 in people with Obstructive Sleep Apnea, run by Jazz Pharmaceuticals at 30 sites in 5 countries.

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

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Sep 2019). 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?

Change in the Maintenance of Wakefulness Test (MWT) (time frame: Week 4 to Week 6). The study lists 2 primary outcomes in all. 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 NCT02348619, 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?
