Micronised Resveratrol as a Treatment for Friedreich Ataxia

---

Brief description of study

The aim of this study is to assess the efficacy of micronised resveratrol as a treatment for FRDA, in terms of reducing the severity of ataxia symptoms at 24 weeks, through a randomised blinded, placebo controlled crossover trial.

Detailed Study Description

Friedreich ataxia (FRDA) is the most common hereditary ataxia, with an estimated prevalence in Caucasians of 1 in 30,000. Neurological features of FRDA are progressive gait and limb ataxia, absent lower limb reflexes, and loss of position and vibration sense. There are currently no treatments proven to alter the natural history of FRDA. Resveratrol is a naturally occurring compound found in red wine, berries, and nuts. It is postulated to have wide-ranging health benefits, including antioxidant, anticarcinogenic, antidiabetic and neuroprotective properties.

The study will be a double-blinded, placebo-controlled randomised 2-period crossover trial of 2g/day of micronised resveratrol in FRDA over 24 weeks. The study will enrol 40 patients with FRDA from 3 sites. The primary outcome measure is the change in modified Friedreich Ataxia Rating Scale (mFARS) score from baseline to 24 weeks.
