What is being measured

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

  1. Change in sleep quality, as assessed by the Pittsburgh Sleep Quality Index (PSQI)

    The PSQI is a 9-question instrument used to measure the quality and patterns of sleep in adults.

    Scoring of the answers is based on a 0 to 3 scale, whereby 3 reflects the negative extreme on the Likert Scale. A global sum of "5"or greater indicates a "poor" sleeper.

    Measured: Baseline, week 5, week 9

Secondary outcomes (5)
  1. Improvement in sleep quality, as assessed by the Huntington's disease (HD) sleep questionnaire

    This questionnaire contained 45 questions that focused on different sleep-related issues such as duration, quality of sleep, abnormal nocturnal behavior and quality of life.

    The questionnaire has a total score of 19 points, scores of (0 - 3) represent the 'normal' range whilst, scores of (4 - 6) reflect 'mild' and scores of 7 and above indicate a 'significant' sleep disturbance.

    Measured: Baseline, week 5, week 9

  2. Improvement in daytime somnolence, as evaluated by the Epworth Sleepiness Scale (ESS)

    The ESS is a questionnaire designed to measure the subject's general level of daytime sleepiness.

    This scale scores from 0-24, with higher scores showing severe excessive daytime sleepiness.

    Measured: Baseline, week 5, week 9

  3. Improvement in self-perceived cognitive function, as assessed by the Quality of Life in Neurological Disorders questionnaire (NeuroQOLv2.0) Cognition Function - Short Form

    It is an 8-question instrument designed and validated to evaluate perceived difficulties in cognitive abilities (e.g., memory, attention, and decision making, or in the application of such abilities to everyday tasks (e.g., planning, organizing, calculating, remembering and learning).

    The score ranges from 0-100, with higher scores meaning a better or worse outcome according to the domain evaluated.

    Measured: Baseline, week 5, week 9

  4. Improvement in global cognitive functioning, as assessed by the Montreal cognitive assessment (MoCA)

    The MoCA was designed as a rapid screening instrument for mild cognitive dysfunction.

    Scores on the MoCA range from zero to 30, with a score of 26 and higher generally considered normal.

    Measured: Baseline, week 5, week 9

  5. Improvement in quality of life, as evaluated by the Huntington's Disease Quality of Life Questionnaire (HDQoL)

    It is a disease-specific scale containing 40 questions, with answers including different types of frequency from "never" to "all of the time".

    Measured: Baseline, week 5, week 9

Questions about this trial

What is this clinical trial studying?

A study testing Melatonin in people with Huntington Disease, run by The University of Texas Health Science Center, Houston at 1 site 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 5 inclusion and 7 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 May 2023. 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 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.

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?

Change in sleep quality, as assessed by the Pittsburgh Sleep Quality Index (PSQI) (time frame: Baseline, week 5, week 9). 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 NCT04421339, 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 May 2023.
