The official eligibility criteria
Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.
Inclusion Criteria:
* Signed informed consents must be obtained prior to participation in the study
* Ambulatory male or female participants between 21 to 70 years of age, inclusive, on the day of Informed Consent signature

* Meets all of the following criteria:
* UHDRS IS score ≥90
* UHDRS TFC score = 13
* UHDRS TMS score = 7-25, inclusive
* CAP100 ≥ 70 Calculation: CAP = Age at study entry × (CAG length - 30) / 6.49
Exclusion Criteria:
* History of gene therapy or cell transplantation or any other experimental brain surgery for the treatment of HD
* Serologic evidence for active viral hepatitis as indicated by:
* positive anti-HBc IgM

In the case of oophorectomy alone, the reproductive status of the woman needs to have been confirmed by follow-up hormone level assessment.

Not medical advice.
Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
