    Lipoic Acid for Treatment of Progressive Multiple Sclerosis: A Phase 2 Randomized Clinical Trial

    Spain R, et al

    Published in Neurology

    Methodology

    Phase 2 randomized, double-blind, placebo-controlled trial of lipoic acid 1200 mg/day for two years in progressive multiple sclerosis, with change in timed 25-foot walk as the primary outcome plus MRI and disability measures.

    Key Findings

    Two years of oral lipoic acid 1200 mg/day did not slow decline in timed walking speed or other clinical and MRI measures compared with placebo in progressive multiple sclerosis; gastrointestinal side effects and dropout were common.

    Conclusions

    Lipoic acid did not slow decline in walking speed or produce clinical effects different from placebo.

    Limitations

    Moderate sample (n=115) for a two-year progressive MS trial, substantial dropout and adherence problems, and a single dose regimen tested.

    Supplements Studied

    LA did not slow decline in walking speed or have other clinical effects different from placebo and was associated with newly described adverse events.
