Change in Total Functional Capacity [ Time Frame: Minimum 12 months up to 48 months ] [ Designated as safety issue: No ]
Study duration depends on each subject's calendar date of enrollment.
To assess the effects of creatine monohydrate (HD-02) on the progression of functional decline in HD as measured by the change in the Total Functional Capacity (TFC) scale over 36 months. [ Time Frame: after approximately 163, 325, & 488 subjects have completed the study ] [ Designated as safety issue: No ]

Clinical symptoms (changes in other UHDRS scores); safety (frequency of adverse events); tolerability (proportion of subjects completing study at assigned dosage level), quality of life, other biological markers. [ Time Frame: Duration of the trial ] [ Designated as safety issue: Yes ]
To assess the long-term safety and tolerability of creatine(HD-02) in HD, its effect on clinical symptoms, quality of life, and effect on biological outcome measures of HD progression as compared to placebo. [ Time Frame: after 50, 150, and 300 subjects have reached 12 months of follow-up and after 50% of the subjects have reached the 36 month visit ] [ Designated as safety issue: Yes ]

Creatine Safety, Tolerability, & Efficacy in Huntington's Disease (CREST-E)
Creatine Safety, Tolerability, & Efficacy in Huntington's Disease (CREST-E)

Huntington's disease (HD) is a slowly progressive disorder that devastates the lives of those affected and their families. There are no treatments that slow the progression of HD, only mildly effective symptomatic therapies are available.Creatine monohydrate is considered a nutritional supplement. The purpose of CREST-E is to test whether high-dose creatine can slow the progressive functional decline that occurs in persons 18 years or older with early clinical features of HD. The long-term safety, tolerability and effectiveness of up to 40 grams daily creatine compared to placebo is studied. A variety of biological processes are assessed for markers of disease activity or progression and creatine effects. Up to 50 active research centers globally will enroll 650 subjects.
