What is being measured

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

  1. To determine the effect of dual release Zaleplon (Zaleplon AP) on Total Sleep Time (TST)

    The change from baseline on the mean of drug nights 1 and 2 relative to placebo.

    Measured: Polysomnography tests for 2 consecutive nights at each treatment arm

Secondary outcomes (3)
  1. To determine the efficacy of Zaleplon AP on Latency to Persistent Sleep (LPS)

    The change from baseline on the mean of drug nights 1 and 2 relative to placebo.

    Measured: Polysomnography tests for 2 consecutive nights at each treatment arm

  2. To determine the efficacy of Zaleplon AP on Wake time After Sleep Onset (WASO)

    The change from baseline on the mean of drug nights 1 and 2 relative to placebo.

    Measured: Polysomnography tests for 2 consecutive nights at each treatment arm

  3. To evaluate the presence of any residual effects using the digital symbol substitution test (DSST) and a memory test

    The change from baseline on the mean of drug nights 1 and 2 relative to placebo.

    Measured: 2 consecutive mornings at each treatment arm

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Zaleplon AP formulation in people with Insomnia, run by Intec Pharma Ltd. at 6 sites in 2 countries.

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 11 inclusion and 17 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 19 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Israel. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To determine the effect of dual release Zaleplon (Zaleplon AP) on Total Sleep Time (TST) (time frame: Polysomnography tests for 2 consecutive nights at each treatment arm). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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?
