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.

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • 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.

Secondary Outcome Measures:
  • 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 ]
