What is being measured

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

  1. Total Sleep Time in the First Two Thirds of the Night

    Total sleep time during the first 2/3 of the night following an 8-hour phase advance bedtime, as measured by PSG. This is representative of trans meridian travel across 8 time zones.

    Measured: 1 Day

Secondary outcomes (5)
  1. Total Sleep Time

    Total Sleep Time as measured by PSG.

    Measured: 1 Day

  2. Latency to Persistent Sleep

    Length of time elapsed between lights out and onset of persistent sleep as measure by PSG.

    Measured: 1 Day

  3. Wake After Sleep Onset

    The amount of wake time during the sleep period after sleep onset (as measured by polysomnography).

    Measured: 1 Day

  4. Next Day Alertness as Measured by the Karolinska Sleepiness Scale (Night 1 Average Score)

    A 9-point scale that measures subjective levels of fatigue by asking how sleepy subjects feel at that moment: 1 = extremely awake to 9 =extremely sleepy/fighting to stay awake.

    Measured: 1 Day

  5. Next Day Alertness as Measured by the Visual Analogue Scale (Night 1 Average Score)

    The VAS was a self-rated scale to assess sleepiness. Participants marked along a 100 mm line to represent their current state of sleepiness, 0 being very sleepy and 100 being very alert. The VAS was administered four times following the dose administration after awakening.

    Measured: 1 Day

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tasimelteon in people with Jet Lag Type Insomnia, run by Vanda Pharmaceuticals at 12 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 4 inclusion and 3 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 15 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 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 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 15 Sep 2023). 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?

Total Sleep Time in the First Two Thirds of the Night (time frame: 1 Day). 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 NCT03373201, 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 15 Sep 2023.
