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

This study has been terminated.
(Results of an interim analysis showed that it was unlikely that creatine was effective in slowing loss of function in early symptomatic Huntington's Disease.)

  Purpose
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.

Condition Intervention Phase
Huntington's Disease Drug: Creatine Monohydrate Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Creatine Safety, Tolerability, & Efficacy in Huntington's Disease (CREST-E)
