Primary Outcome Measures:
  • Change From Baseline (Average of Screening and Day 0) in the Average TMC Scores From Weeks 9 & 12 [ Time Frame: Screening, Day 0, Weeks 9, 12 ]
    Total TMC score is a sum of chorea scores which range 0-28, with a decrease indicating improvement in chorea


Secondary Outcome Measures:
  • Number of Participants With Treatment Success at the End of Therapy as Measured by the Patient Global Impression of Change (PGIC) [ Time Frame: 12 weeks ]
    A treatment success is defined as Much or Very Much Improved at the Week 12 visit. The PGIC is a 7-point Likert Scale, ranging from very much worse to very much improved

  • Number of Participants With Treatment Success at the End of Therapy Based on Clinical Global Impression of Change (CGIC) [ Time Frame: 12 weeks ]
    A treatment success is defined as Much or Very Much Improved at the Week 12 visit. The PGIC is a 7-point Likert Scale, ranging from very much worse to very much improved. The clinician was asked to comment about the subject.

  • Change in the Short Form 36 Health Survey (SF-36) Physical Functioning Score (Based on Items 3a to 3j) From Baseline to Week 12 [ Time Frame: Baseline, 12 weeks ]
    Change in the Short Form 36 Health Survey (SF-36) physical functioning score (based on items 3a to 3j) from Baseline to Week 12. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.

  • Change in Berg Balance Test (BBT) [ Time Frame: Baseline, 12 weeks ]
    The Berg Balance Test (BBT) is a 14-item assessment of sitting, standing, transferring, and turning. Each task ranging from standing up from a sitting position, to standing on one foot each task is given a score of zero (unable) to four (independent), and the final measure is the sum of all of the scores.The scale range, which is 0-56, with higher scores indicating better balance/lower fall risk.

Detailed Description:
This is a randomized, double-blind, placebo-controlled, parallel-group study designed to evaluate the efficacy, safety and tolerability of SD-809 for the treatment of chorea associated with Huntington's Disease. Approximately 90 subjects will be randomized (1:1) into the study, with approximately 45 subjects receiving SD-809 and 45 subjects receiving placebo. The study will be conducted at approximately 30 centers in the U.S. and Canada.
