A randomized, placebo-controlled trial of coenzyme Q 10 and remacemide in Huntington’s disease

The Huntington Study Group·2001·Neurology

Abstract

OBJECTIVES: To determine whether chronic treatment with coenzyme Q10 or remacemide hydrochloride slows the functional decline of early Huntington's disease (HD). METHODS: The authors conducted a multicenter, parallel group, double-blind, 2 x 2 factorial, randomized clinical trial. Research participants with early HD (n = 347) were randomized to receive coenzyme Q10 300 mg twice daily, remacemide hydrochloride 200 mg three times daily, both, or neither treatment, and were evaluated every 4 to 5 months for a total of 30 months on assigned treatment. The prespecified primary measure of efficacy was the change in total functional capacity (TFC) between baseline and 30 months. Safety measures included the frequency of clinical adverse events. RESULTS: Neither intervention significantly altered the decline in TFC. Patients treated with coenzyme Q10 showed a trend toward slowing in TFC decline (13%) over 30 months (2.40- versus 2.74-point decline, p = 0.15), as well as beneficial trends in some secondary measures. There was increased frequency of nausea, vomiting, and dizziness with remacemide and increased frequency of stomach upset with coenzyme Q10. CONCLUSIONS: Neither remacemide nor coenzyme Q10, at the dosages studied, produced significant slowing in functional decline in early HD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
