Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Modified Motor Score (mMS) (Sum of Score of Items 4-10 and 13-15 of the Unified Huntington's Disease Rating Scale [UHDRS] Motor Assessments) at Week 26

    The mMS is a subscale of the UHDRS total motor score and comprises 13 responses from the 10 items, 4-10 and 13-15, from the UHDRS motor assessment. The items for mMS include dysarthria, tongue protrusion, finger taps (right and left), pronate/supinate hands (right and left), luria - first-hand-palm sequencing, arms rigidity (right and left), body bradykinesia, gait, tandem walking, and retropulsion pull test. Each of these items are rated on a scale of 0 (normal) to 4 (marked impairment). Total score ranges from 0 to 52, with higher scores indicating more severe motor impairment.

    Baseline, Week 26

Secondary Outcomes (7)

  • The UHDRS Functional Assessment at Week 26

    Week 26

  • Number of Participants With Clinical Global Impression - Improvement (CGI-I) Score

  • Change From Baseline in Stroop Word Reading Test at Week 26

  • Change From Baseline in Total UHDRS Behavioral Assessment Score at Week 26

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Able to provide written Informed Consent prior to any study related procedure.
  • Huntington's disease diagnosed with the aid of clinical features and a positive family history and/or the presence of ≥ 36 CAG repeats in the Huntington gene.
  • Male or female age ≥ 30 years.
  • Willing and able to take oral medication and able to comply with the study specific procedures.
  • Ambulatory, being able to travel to the assessment centre, and judged by the Investigator as likely to be able to continue to travel for the duration of the study.
  • Availability of a caregiver or family member to accompany the participant.
  • A sum of ≥ 10 points on the mMS at the screening visit.
  • For participants taking allowed antipsychotic medication, the dosing of medication must have been kept constant for at least 6 weeks before randomization. The allowed antipsychotic medication is Amisulpride, Haloperidol, Olanzapine, Risperidone, Sulpiride, or Tiapride.
  • For participants taking allowed antidepressant or other psychotropic medication, the dosing of medication must have been kept constant for at least 6 weeks before randomization.
  • Willing to provide a blood sample for CAG analysis (where CAG result is not already available).
  • In France only, the participant must be affiliated to a social security system or be a beneficiary of such a system.

You may not qualify if:

  • Unable to give written informed consent.
  • Treatment with any non-allowed antipsychotic medication within 12 weeks of randomization. The non-allowed antipsychotic medication is any medication other than Amisulpride, Haloperidol, Olanzapine, Risperidone, Sulpiride, or Tiapride.
  • Treatment with the antidepressants Fluoxetine or Paroxetine within 6 weeks of randomization.
  • Use of Tetrabenazine within 12 weeks of randomization, or at any time during the study period.
  • Treatment with any investigational product within 4 weeks of randomization.
  • Use of tricyclic antidepressants, class I antiarrhythmics, and strong CYP2D6 inhibitors such as Ajmalicine, Chinidin/Quinidine and Ritonavir, within 6 weeks of randomization.
  • Participants previously included into this study.
  • A prolonged QTc interval at screen (defined as a QTc interval of \> 450 milliseconds \[msec\] for males or \> 470 msec for females), or other clinically significant heart conditions.
  • Creatinine clearance \<40 milliliters (mL)/minute (min) as measured at the screening visit.
  • Any clinically significant, abnormal, baseline laboratory result which in the opinion of the Investigator, affects the participants' suitability for the study or puts the participant at risk if he/she enters the study.
  • Clinically significant hepatic or renal impairment.
  • Participants with a history of epilepsy or a history of seizure(s) of unknown cause.
  • Severe intercurrent illness, which, in the opinion of the Investigator, may put the participant at risk when participating in the trial or may influence the results of the trial or affect the participants' ability to take part in the trial.
  • Alcohol and/or drug abuse as defined by Diagnostic and Statistical Manual - Fourth Edition - Text Revision (DSM IV-TR) criteria for substance abuse - this includes the illicit use of cannabis within the last 12 months.
  • Participants with suicidal ideation, defined as a positive score on criteria for major depressive episode, item A9 on the DSM-IV-TR criteria for a Major Depressive Episode.
  • +6 more criteria
