Abstract Details

An Open Label Clinical Pilot Study of Resveratrol as a Treatment for Friedreich Ataxia
Movement Disorders
S43 - (-)
006
FRDA is due to a triplet repeat expansion in the FXN gene, resulting in deficiency of the mitochondrial protein frataxin. Resveratrol is a plant-derived compound. It was identified to increase frataxin expression in cellular and mouse models of FRDA, and has anti-oxidant properties.
27 participants were enrolled in this open-label sequential clinical pilot study. Thirteen participants received resveratrol 1g daily (low-dose), and fourteen received resveratrol 5g daily (high-dose).
24 participants completed the study (twelve in each dosage group). Preliminary assessment of selected secondary outcome measures has been completed. Improvement in ataxia was evident in the high-dose group (change in ICARS, International Cooperative Ataxia Rating Scale -1.9 points, 95% CI -3.1, -0.8, p=0.004) but not the low-dose group (change in ICARS -0.3 points, 95% CI -3.2, 2.6, p=NS). A significant decrease in the oxidative stress marker plasma F2 isoprostane levels occurred in the high-dose group (-216.9 pmol/L plasma, 95% CI -301.4, -132.2, p<0.001) but not the low-dose group (-45.2 pmol/L plasma, 95% CI -152.9, 62.6, p=0.38, p=NS). Change in lymphocyte frataxin levels and other secondary outcome measures will be presented. No serious adverse events were recorded. Gastrointestinal side effects were a common dose-related adverse event.
Preliminary analysis of results from this open-label trial suggests that treatment with high-dose resveratrol for 12 weeks improves some clinical and biological markers of FRDA. A placebo-controlled study is required to assess whether resveratrol is clinically beneficial in FRDA.
