BACKGROUND: Cysteamine has been demonstrated as potentially effective in numerous animal models of Huntington's disease.
METHODS: Ninety-six patients with early-stage Huntington's disease were randomized to 1200 mg delayed-release cysteamine bitartrate or placebo daily for 18 months. The primary end point was the change from baseline in the UHDRS Total Motor Score. A linear mixed-effects model for repeated measures was used to assess treatment effect, expressed as the least-squares mean difference of cysteamine minus placebo, with negative values indicating less deterioration relative to placebo.
RESULTS: At 18 months, the treatment effect was not statistically significant - least-squares mean difference, -1.5 ± 1.71 (P = 0.385) - although this did represent less mean deterioration from baseline for the treated group relative to placebo. Treatment with cysteamine was safe and well tolerated.
CONCLUSIONS: Efficacy of cysteamine was not demonstrated in this study population of patients with Huntington's disease. Post hoc analyses indicate the need for definitive future studies. © 2017 International Parkinson and Movement Disorder Society.
