The Unified Huntington's Disease Rating Scale (UHDRS) behavioral subscale assesses frequency and severity of psychiatric-related symptoms, including depressed mood, apathy, low self-esteem/guilt, suicidal thoughts, anxiety, irritable behavior, aggressive behavior, obsessional thinking, compulsive behavior, delusions, and hallucinations. A total score was calculated by summing up all the individual behavioral frequency items (range 0-56) with higher scores representing more severe behavioral impairment. (NCT00608881)
Timeframe: Baseline and Month 60

---|---|
A - Coenzyme Q10 2400 mg/Day | 1.39 |
B - Placebo | 1.43 |
The Unified Huntington's Disease Rating Scale (UHDRS) behavioral subscale assesses frequency and severity of psychiatric-related symptoms, including depressed mood, apathy, low self-esteem/guilt, suicidal thoughts, anxiety, irritable behavior, aggressive behavior, obsessional thinking, compulsive behavior, delusions, and hallucinations. The total score is the sum of the product of the individual behavioral frequency and severity items (range 0-176) with higher scores representing more severe behavioral impairment. (NCT00608881)

The motor section of the Unified Huntington's Disease Rating Scale (UHDRS) assesses motor features of Huntington disease with standardized ratings of oculomotor function, dysarthria, chorea, dystonia, gait, and postural stability. The total motor score is the sum of all the individual motor ratings, with higher scores (124) indicating more severe motor impairment than lower scores. The score ranges from 0 to 124. (NCT00608881)

The primary outcome variable at the start of the trial was the change in TFC score from baseline to Month 60. The Data and Safety Monitoring Board recommended to the trial leadership that they reconsider how they accommodate missing data from subjects who die in their primary analysis of the change in TFC score. Based on these recommendations, the trial leadership changed the primary analysis to that of a joint rank approach. TFC consists of five ordinally scaled items assessing a person's capacity with: (1) occupation; (2) financial affairs; (3) domestic responsibilities; (4) activities of daily living; and (5) independent living.
