Summary
Brief summary
HDClarity will seek at least 2500 research participants at different stages of Huntington's
disease (HD). The primary objective is to collect a high quality CSF sample for evaluation of
biomarkers and pathways that will enable the development of novel treatments for HD. The
secondary objective is to generate a high quality plasma sample collection matching the CSF
collections, which will also be used to evaluate biomarkers and pathways of relevance to HD
research and development.
