What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Deutetrabenazine Oral Tablet [Austedo]Drug

    Also called Austedo

    The participants randomized to this group will receive oral deutetrabenazine for 8 weeks. Week 1: 6 mg tab once daily; Week 2: 6 mg tab (BID); Week 3: 9 mg tab (BID); Week 4: 12 mg tab (BID); Week 5: 15 mg (6 mg tab + 9 mg tab BID); Week 6: 18 mg (9 mg tab + 9 mg tab BID); Week 7: 21 mg (9 mg tab + 12 mg tab BID); Week 8: 24 mg (12 mg tab BID).

  • Placebo oral tabletDrug

    Also called Placebo

    The participants randomized to this group will receive oral placebo for 8 weeks. Week 1: 6 mg tab once daily; Week 2: 6 mg tab (BID); Week 3: 9 mg tab (BID); Week 4: 12 mg tab (BID); Week 5: 15 mg (6 mg tab + 9 mg tab BID); Week 6: 18 mg (9 mg tab + 9 mg tab BID); Week 7: 21 mg (9 mg tab + 12 mg tab BID); Week 8: 24 mg (12 mg tab BID).

What is being measured

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

  1. Efficacy of deutetrabenazine to control symptoms of dysphagia associated with Huntington's disease.

    The change in swallow function/dysphagia from baseline to maintenance therapy using the clinical swallow assessment Huntington's Disease Dysphagia Scale (HDDS). The Huntington's Disease Dysphagia Scale is an 11-item scale used to monitor swallowing difficulties in persons in early to advanced disease stages. The Huntington's Disease Dysphagia Scale includes questions related to the preparatory oral, oral, pharyngeal, and esophageal phases of swallow. The response options are the following: Question 1-4 and 6-11: 1 No, almost never; 2 Yes, seldom; 3 Yes, sometimes; 4 Yes, frequently; 5 Yes, almost always. Question 5: 1 Yes, almost always; 2 Yes, frequently; 3 Yes, sometimes; 4 Yes, seldom; 5 No, almost never. Higher scores mean a worse outcome.

    Measured: 18 months

  2. Non-instrumental assessment of the efficacy of deutetrabenazine to control symptoms of dysphagia associated with Huntington's disease.

    Non-instrumental assessment and symptoms of dysphagia using the Bedside Swallowing Assessment Scale. The Bedside Swallowing Assessment Scale interpretation: Level 1: irrelevant alterations, scores ≤ 19; level 2: average alterations, scores 20-23; level 3: severe alterations, scores ≥ 24. Higher scores mean a worse outcome.

    Measured: 18 months

  3. Instrumental assessment of the efficacy of deutetrabenazine to control symptoms of dysphagia associated with Huntington's disease.

    Assessment of pharyngeal and esophageal dysphagia using the Videofluoroscopic Swallowing Study, also known as the Modified Barium Swallow Study. The instrumental assessment provides a description of any anatomical differences and physiological problems that may be associated with the patients' symptoms in all phases of the swallow. Results from the videoflourographic study are used to rate the severity of dysphagia according to the Dysphagia Outcome and Severity Scale. The Dysphagia Outcome and Severity Scale scores range from 1 to 7, with 7 representing normal swallowing and 1 representing severe dysphagia.

    Measured: 18 months

Secondary outcomes (3)
  1. Effect of deutetrabenazine on body weight in HD patients.

    Secondary endpoints are treatment success from baseline to maintenance therapy on body weight. Body weight will be calculated in kilograms.

    Measured: 18 months

  2. Effect of deutetrabenazine on body mass index in HD patients.

    Secondary endpoints are treatment success from baseline to maintenance therapy on body mass index. Body mass index will be calculated by dividing the weight in kilograms by the square of the height in meters (kg/m2).

    Measured: 18 months

  3. Effect of deutetrabenazine on fat distribution in HD patients.

    Secondary endpoints are treatment success from baseline to maintenance therapy on body fat distribution. Body fat distribution will be estimated using skinfold caliper measurements of skinfold thickness at four sites: scapular, biceps, triceps and suprailiac, together with arm and leg circumferences.

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Deutetrabenazine Oral Tablet [Austedo] in people with Huntington Disease, run by Fundacion Huntington Puerto Rico at 1 site in Puerto Rico.

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 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: stopped early, as of the sponsor's last update on 27 Feb 2025. 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 Puerto Rico. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Efficacy of deutetrabenazine to control symptoms of dysphagia associated with Huntington's disease. (time frame: 18 months). The study lists 3 primary outcomes in all. 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?
