- 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.

- BACKGROUND: Riluzole retards striatal glutamate release and pathologic consequences in neurotoxic animal models of Huntington's disease (HD).OBJECTIVE: To determine the dosage-related impact of riluzole on chorea in HD.METHODS: An 8-week double-blind dose-ranging multicenter study of riluzole was conducted in 63 subjects (32 women, 31 men) with HD who were randomized to receive placebo, riluzole 100 mg/day, or riluzole 200 mg/day. The prespecified outcome measure was change in the total maximal chorea score of the Unified Huntington's Disease Rating Scale (UHDRS).RESULTS: Fifty-six (89%) subjects completed the study. A reduction (p < 0.01) in chorea at 8 weeks was found using a linear trend test with dose. Comparing the groups individually, the reduction in chorea for the riluzole 200-mg/day group (-2.2 +/- 3.3) was different (p = 0.01) from placebo (+0.7 +/- 3.4), but the riluzole 100-mg/day group (-0.2 +/- 2.9) was not. Riluzole did not improve other motor, cognitive, behavioral, or functional components of the UHDRS. Alanine aminotransferase was elevated in a dosage-dependent fashion (p = 0.01).CONCLUSIONS: Over 8 weeks of treatment, riluzole 200 mg/day ameliorated chorea intensity in HD without improving functional capacity or other clinical features of illness. Riluzole 200 mg/day was attended by reversible liver transaminase abnormalities that would require monitoring in long-term studies.
