简要总结
A randomized, double-blind, placebo-controlled, flexible dose study to evaluate efficacy and safety of Pramipexole versus placebo for 6 weeks in children (age 6-17) diagnosed with Tourette Disorder according to DSM IV criteria. The primary efficacy measure will be the Total Tic Score (TTS) of the Yale Global Tic Severity Scale (YGTSS) at 6 weeks.

结局指标
主要结局
Mean Change From Baseline in Total Tic Score of the Yale Global Tic Severity Scale
时间窗: baseline 6 weeks
Total Tic Score is the sum of ten individual ratings of the impairment due to tics. Each scale ranges from 0 (None/Absent) to 5 (Severe) and total score ranges from 0 to 50. Analysis was adjusted for baseline total tic score and age as linear covariates.
