NCT02102698

Brief Summary

Tourette's Syndrome is a neurological disease characterized by motor and vocal tics. It has been hypothesized that abnormal interactions of dopamine with its receptors may cause the tics. The purpose of this study is to test the hypothesis that a drug (ecopipam) that selectively blocks dopamine D1/D5 receptors can reduce the frequency and severity of the tics.

Outcome Measures

Primary Outcomes (1)

  • Yale Global Tic Severity Scale - Total Tic Score

    The Yale Global Tic Severity Scale (YGTSS) is the standard rating scale used to assess the effects of a new treatment on the symptoms of Tourette's Disorder (TD). The YGTSS is a clinician-rated, multi-dimensional instrument for assessing tic symptom severity in children and adults with TD. Both motor and vocal tics are assessed for symptom number, frequency, intensity, complexity, and interference on a 0-5 Likert scale. Scores from each dimension are totaled to reflect the severity of motor tics (range 0-25) (min of 0 to max 25), vocal tics (range 0-25) (min of 0 to max 25) and combined tics, or Total Tic Score (TTS) (range 0-50) (min of 0 to max of 50, sum of motor tics and vocal tic scores). For all scores, lower score represents better outcome. The primary outcome measure is the YGTSS-TTS (Yale Global Tic Severity Scale Total Tic Score which includes both the motor and phonic tic scores).

Eligibility Criteria

Age7 Years - 17 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Subjects must exhibit both motor and vocal tics.
  • Subjects must have a minimum score of 20 at both Screening and Baseline (just prior to the first treatment) on the Yale Global Tic Severity Scale.
  • Subjects must be age (≥ 7 to \< 18 years of age)
  • Subjects must weigh ≥ 20 kg (45 lbs)
  • Adolescent females of childbearing potential who are sexually active must be using effective contraception (i.e., oral contraceptives, intrauterine device, double barrier method of condom and spermicide) and agree to continue use of contraception for the duration of their participation in the study. They must also agree to use contraception for 30 days after their last dose of study drug.
  • Sexually active male subjects must use a barrier method of contraception during the study and agree to continue the use of male contraception for at least 30 days after the last dose of study drug.
  • Subject's parent or legal guardian must execute a written informed consent.
  • Subject must execute a written informed assent.

You may not qualify if:

  • Subjects who have unstable medical illness or clinically significant abnormalities on laboratory tests, or ECG at Screening.
  • Subjects with a major depressive episode in the past 2 years
  • Subjects with a history of attempted suicide
  • Subjects with clinically significant suicidality (based on the Columbia Suicide Rating Scale (C-SSRS)
  • Subjects with a first-degree relative with a major depressive episode that resulted in any psychiatric hospitalization, or attempted/ completed suicide with the exception of a hospitalization for post-partum depression.
  • Subjects with a history of seizures (excluding febrile seizures that occurred \>2 years in the past)
  • Subjects with a myocardial infarction within 6 months.
  • Girls who are currently pregnant or lactating.
  • Subjects who have a need for medication (other than ecopipam) with possible effects on TS symptoms (i.e., lithium, psychostimulants)
  • Subjects who have a need for medications which would have unfavorable interactions with ecopipam, e.g., dopamine antagonists or agonists \[including bupropion\], tetrabenazine, or monoamine oxidase inhibitors.
  • Subjects with a lifetime history of bipolar disorder type I or II, dementia, schizophrenia, or any psychotic disorder determined by the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders - 4th Edition (DSM-IV) Axis-I Disorders (SCID).
  • Subjects with current or recent (past 3 months) DSM-IV substance abuse or dependence (with the exception of nicotine).
  • Subjects with positive urine drug screen (cocaine, amphetamine, methamphetamine, tetrahydrocannabinol (THC), benzodiazepines, barbiturates, phencyclidine (PCP), opiates) at Screening. Subjects with urine positive only for benzodiazepines and/or marijuana (i.e., a user but not an abuser as based on DSM-IV criteria) may be eligible.
  • Subjects who have had previous treatment with ecopipam.
  • Subjects who have had treatment with:
  • +5 more criteria
