Official title
Open-Label Trial of Sulforaphane in Premutation Carriers With FXTAS to Find Biomarkers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
FXTAS is a rare genetic progressive neurodegenerative disorder, linked to a trinucleotide repeat expansion in the FMR1 gene. FXTAS is characterized by tremor and ataxia in addition to atrophy and white matter disease in the central nervous system (CNS). In addition to the major clinical observations of intention tremor and gait dysfunction, minor symptoms of parkinsonism, neuropathy, and cognitive decline also significantly impact individuals with FXTAS. The dietary supplement being tested in this study is called Sulforaphane. It is found in broccoli and similar cruciferous vegetables and may cause some gas and discomfort. This is not a study looking at clinical efficacy but instead a study of molecular outcome measures. Investigators want to get more information about how Sulforaphane affects specific biomolecular markers captured in blood. In this study, participants will be taking an increasing amount of the Sulphoraphane supplement pills (238mg/tablet), starting at 1 and increasing to 6, every morning at breakfast for 6 months. In addition, there will be a total of 3 visits (Initial, 3-month and 6-month) to the MIND Institute where participants will be evaluated. At each visit (3 total) participants will undergo a battery of medical and neurologic exams which make take 2-3 days to complete each time. Participants and/or their caregivers will also be asked to fill out questionnaires/surveys. At the initial visit and at 6 months, we will collect blood for analysis. Two MRI scans will be done, also at the initial visit and at 6 months.
