About this study

Official title: Z-Drugs for the Treatment of Sleep Disorders in Alzheimer's Disease: a Randomized, Triple-blind, Placebo-controlled Study

The purpose of this study is to determine whether Zolpidem and Zoplicone are efective in the treatment of sleep disorders in Alzheimer's disease (AD)

Read the detailed description

Sleep disorders (SD) affects 35 to 50 percent of patients with AD. These disorders often make caring for patients at home very difficult. Zolpidem and Zoplicone are prescribed drugs for sleep disorder in AD patients.

Being tested
Zolpidem, Zoplicone, Placebo
Keywords

What is being measured

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

  1. Nighttime Total Sleep Time

    Mean Total Sleep Time (in minutes) during the 12h nocturnal period (8:00pm-8:00am) after 2 weeks under treatment

    Measured: Baseline, 14 days follow-up

Secondary outcomes (7)
  1. Daytime Total Sleep Time

    Daytime Total Sleep Time (in minutes) during the 12h daytime period (8:00am-8:00pm) after 2 weeks under treatment

    Measured: Baseline, 14 days follow-up

  2. Ratio of daytime to nighttime sleep

    Daytime Total Sleep Time / Nighttime Total Sleep Time

    Measured: Baseline, 14 days follow-up

  3. Nighttime Wake after Sleep Onset

    Nighttime Wake after Sleep Onset (in minutes) during the 12h nocturnal period (8:00pm-8:00am) after 2 weeks under treatment

    Measured: Baseline, 14 days follow-up

  4. Proportion of sleep time at nighttime

    Proportion of sleep time (%) during the 12h nocturnal period (8:00pm-8:00am) after 2 weeks under treatment

    Measured: Baseline, 14 days follow-up

  5. Proportion of patients with gain of at least 30 minutes in Total Sleep Time

    Proportion of patients with gain of at least 30 minutes in Total Sleep Time after 2 weeks under treatment

    Measured: Baseline, 14 days follow-up

  6. Differences between sleep efficiency between the two treatments.

    Analyze possible differences between sleep efficiency between the two treatments after 2 weeks under treatment

    Measured: Baseline, 14 days follow-up

  7. Nighttime Number of Awakenings

    Change in scores of nighttime number of awakenings from baseline to intervention weeks

    Measured: Baseline, 14 days follow-up

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zolpidem and Zoplicone in people with Sleep and Sleep Disorders, run by Brasilia University Hospital at 1 site in Brazil.

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 13 inclusion and 9 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 10 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. 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?

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?

Nighttime Total Sleep Time (time frame: Baseline, 14 days follow-up). 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 NCT03075241, 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 10 Nov 2020.
