  Eligibility

Ages Eligible for Study:   18 Years to 65 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Voluntarily provide informed consent, or have a legally authorized representative (LAR) provide informed consent with subject assent, in accordance with local regulations and governing Institution Review Board (IRB) requirements prior to any procedures or evaluations performed specifically for the sole purpose of the study (other than the Montreal Cognitive Assessment (MoCA) to assess capacity to provide informed consent). Capacity to provide informed consent will be determined by the MoCA and investigator judgment according to the following:

    • Have a score of greater than or equal to 21 on the MoCA and is competent to provide informed consent, in the judgment of the investigator.
    • Have a score of less than 21 on the MoCA and is competent to provide informed consent, in the judgment of a mental health professional (independent of the investigator).
    • Have a score of less than 21 on the MoCA and is not competent to provide informed consent, in the judgment of a mental health professional (independent of the investigator), and has a LAR provide informed consent with assent by the subject.
  2. Have a clinical diagnosis of HD, confirmed by either CAG repeat number of greater than or equal to 39 or a positive family history (a first degree relative with a clinical diagnosis of HD) if CAG repeat number is not known.
  3. Are 18 to 65 years inclusive at screening visit (Visit 1).
  4. Have a UHDRS Total Functional Capacity greater than or equal to 7 at Visit 1.
  5. If currently taking antipsychotic medication(s), have been on a stable regimen for at least 60 days prior to randomization.
  6. Have completed at least 10th grade or equivalent of formal education.
  7. Are fluent in English.
  8. If female, are either a) not of childbearing potential (i.e., surgically sterilized or post-menopausal for more than 1 year) or b) have a negative pregnancy test and if sexually active must agree to use a medically reliable form of contraception throughout the study. Acceptable methods of contraception include a reliable intrauterine device, hormonal contraception or spermicide in combination with a barrier method.
  9. If male, are either a) not of reproductive potential or b) if sexually active must agree to use a medically reliable form of contraception throughout the study. Acceptable methods of birth control include spermicide in combination with a barrier method, or subjects' female partner is willing to use medically acceptable methods of birth control.
  10. Have normal clinical laboratory test results and ECG, or results with minor deviations, which are not considered to be clinically significant by the investigator.

Exclusion Criteria:

  1. Have a history or presence of significant cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, or neurological disorders other than HD which, in the opinion of the investigator, increases the risk of the study drug or may confound the interpretation of study measures.
  2. Have unstable or severe depression, in the opinion of the investigator.
  3. Have alcohol or drug abuse or dependence, as defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision.
  4. Have received treatment with an investigational drug or device within 60 days prior to Visit 1.
  5. Are pregnant or lactating.
  6. Are an employee of Omeros, an investigator, or study staff member, or their immediate family member.
