NCT00206323

Brief Summary

Previous studies using topiramate in Tourette subjects have shown that with the use of this medication subjects report that their tics get better. The purpose of this study is to study if topiramate improves the symptoms of Tourette syndrome, such as motor tics, or other associated symptoms such as attention or obsessive-compulsive problems.

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Total Tic Score at Day 70

    A component of the Yale Global Tic Severity Scale (YGTSS), the change from baseline in Total Tic Score (TTS) at visit 5 (day 70) is the pre-defined primary endpoint. The Total Tic Score (TTS) is a summation of the Total Motor Tic and Total Phonic Tic Scores. The Overall Impairment Rating is rated on a 50-point scale anchored by 0 (No impairment) and 50 (Severe impairment).

  • Subjects with mental retardation.
  • Subjects with progressive or degenerative neurological disorders or a structural disorder of the brain from birth, trauma or past infection.
  • Subjects taking more than one agent for the treatment of tics, more than one agent for the treatment of comorbid symptoms or more than one agent for the treatment of ADHD and/or the dose of the current treatment has not been stable for a minimum of 6 weeks.
