UNIQURE AMT-130
Recruiting
The European Phase Ib/II clinical trial of AMT-130 for the treatment of HD will explore the safety, proof of concept, and dosing in 15 total patients with with early manifest Huntington’s disease split into a five person manifest Huntington’s disease split into a five person, low-dose open-label(patients know what they are getting) cohort, followed by a nine patient, higher-dose open-label cohort. All patients will be dosed with AMT-130. The therapeutic goal is to inhibit the production of the mHTT. Using AAV vectors to deliver micro-RNAs directly to the brain. A one time injection.

Exclusion criteria:
- Evidence of suicide risk
- Receipt of an experimental agent within 60 days or five half-lives prior to Screening or anytime over the duration of this study.
- Participation in an investigational trial or investigational paradigm (such as exercise/physical activity, cognitive therapy, brain stimulation, etc.) within 60 days prior to Screening or anytime over the duration of this study.

- Hospitalization for any major medical or surgical procedure involving general anesthesia within 12 weeks of Screening or planned during the study.
- Current or recurrent disease, infection, or other significant concurrent medical condition or medications that could confound clinical and laboratory evaluations or could affect a subject’s safety or their ability to undergo the neurosurgical procedure or comply with the procedures and study visit schedule
