SHIELD HD is an international, multisite, prospective, longitudinal cohort natural history study to assess the natural history of HD and its biomarkers that are associated with modulation of the number of cytosine-adenine-guanine (CAG) repeats in the mutant Huntingtin (HTT) gene.
Approximately 60 patients will be enrolled into the study and followed for up to 24 months at clinical sites in North America and Europe.
The results of this study will inform assessments for a future interventional treatment trial.

- DDR gene expression [ Time Frame: 2 years ]To assess deoxyribonucleic acid (DNA) damage repair (DDR) gene expression in accessible biofluids and disease trajectories for established and novel biomarkers and clinical outcomes.
- Compare rates of change in biomarkers for disease progression [ Time Frame: 2 years ]To compare the rates of change for different outcomes and cytosine adenine guanine (CAG) age product (CAP) Scores.
- Additional biomarkers to be examined [ Time Frame: 2 years ]The exploratory objectives of this study are to be determined and may include the examination of additional biomarkers present in CSF, plasma, and whole blood, including but not limited to mutant HTT (mHTT) protein, cytokines, and others, as well as clinical markers of progression.
