简要总结
This observational study will establish a clinical baseline and measure changes over time in movement, thinking, behavior, brain imaging, blood and spinal fluid markers in subjects with early stage Huntington's disease. Participants enrolled in this study may be eligible to participate in a future planned study of stem cell therapy for Huntington's Disease (HD).
In-person study visits occur at screening, baseline, and every 6 months thereafter for a minimum of 12 months, with interim phone call assessments.
详细描述
In PRE-CELL the investigators propose to enroll a cohort of early-stage HD patients in a prospective observational study designed to characterize clinical, neuro-imaging, laboratory and biomarker correlates of disease progression over 12-18 months. Subjects who complete a minimum of 12 months' participation in this trial will be candidates for enrollment in the future planned Phase 1 trial of intrastriatal delivery of mesenchymal stem cell (MSC)/Brain-derived neurotrophic factor (BDNF).
