Primary Outcome Measures:
  • A comparison between the mean changes from baseline in the Dimebon 20 mg TID treatment group and the placebo group on the MMSE [ Time Frame: Week 26 ] [ Designated as safety issue: No ]
  • A comparison of the distributions of the CIBIC-plus (ADCS CGIC)in the Dimebon 20 mg TID treatment group and the placebo group [ Time Frame: Week 26 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • A comparison between the mean changes from baseline of the Dimebon 20 mg TID treatment group and the placebo group on the NPI [ Time Frame: Week 26 ] [ Designated as safety issue: No ]
  • A comparison between the mean changes from baseline of the Dimebon 20 mg TID treatment group and the placebo group on the ADCS-ADL [ Time Frame: Week 26 ] [ Designated as safety issue: No ]
  • A comparison between the mean changes from baseline of the Dimebon 20 mg TID treatment group and the placebo group on the UHDRS'99 Total Motor Score [ Time Frame: Week 26 ] [ Designated as safety issue: No ]

20 mg Dimebon orally TID

Detailed Description:

This study is a multicenter Phase 3, randomized, double-blind, placebo-controlled safety and efficacy study of Dimebon treatment in subjects with Huntington disease (HD). The study will evaluate Dimebon 20 mg three times daily (TID) administered orally (PO) for six months (26 weeks) compared with matching placebo TID for the primary safety and efficacy analyses. Safety and tolerability will be assessed by recording of adverse events and by monitoring of vital signs, physical examinations, safety laboratory evaluations, and 12-lead electrocardiogram(ECG)assessments.
