What this trial studies
HDClarity is an observational initiative aimed at recruiting at least 2500 participants at various stages of Huntington's disease. The study focuses on collecting high-quality cerebrospinal fluid (CSF) and plasma samples to evaluate biomarkers and pathways relevant to the disease. Participants will attend annual visits for medical history assessments and biosample collection, with the option for additional sampling in the first year. This longitudinal approach allows for comprehensive data collection to facilitate therapeutic development for Huntington's disease.
Why it matters
Potential benefit: If successful, this initiative could lead to the identification of new biomarkers and therapeutic targets for Huntington's disease.
How similar studies have gone: Other studies focusing on biomarker collection for neurodegenerative diseases have shown promise, indicating that this approach may yield valuable insights.
