- Original description
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.Read full original descriptionShow less
