Ecopipam Treatment of Tourette Syndrome

August 27, 2015 updated by: Psyadon Pharma
Tourette's Syndrome is a neurological disease characterized by verbal and motor tics. The currently available drug treatments are considered to be inadequate. This clinical trial is designed to test if ecopipam is effective for the treatment of Tourette's Syndrome in adults.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Tourette's Syndrome is a neurological disease characterized by verbal and motor tics. Although its causes are unknown, many researchers believe that changes in brain chemicals (called neurotransmitters) are critically involved. One of these neurotransmitters is called dopamine, and it exerts its actions through its receptors (called D1-type or D2-type). It has been suggested that the symptoms of Tourette's Syndrome are due to an overactivity at the D1-type receptor. Ecopipam is a selective antagonist of the D1-type receptors. The present clinical trial is designed to test if ecopipam is able to relieve the symptoms of the disease in adults patients with Tourette's Syndrome. Eligible patients will be treated for eight weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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 treatment with:

    • investigational medication or depot neuroleptics within 3 months
    • fluoxetine within 6 weeks

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Yale Global Tic Severity Score
Time Frame: 8 weeks
The Yale Global Tic Severity Score is a composite of subject reported severity of motor (range 0-25) and vocal (range 0-25) tics , as well as an impairment score (range 0-50). The outcome we are using is the Total Tic Severity score which is the sum of the motor and vocal tic severity scores (range 0-50). The higher the score on this scale, the more severe the symptoms. A positive drug effect is associated with a decrease from baseline.
8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adult Attention Deficit/Hyperactivity Disorder (ADHD) Self-report Symptom Checklist (ASRS)
Time Frame: Every 7 days
This is a standard measure of ADHD severity that is typically used in these types of clinical trials.
Every 7 days
Hamilton Depression Scale

Every 7 days
Premonitory Urge for Tics Scale (PUTS-1)
Time Frame: Every 7 days
This is a measure of the tic behavior that is seen in Tourette's patients, and it is typically used in these types of trials.
Every 7 days
Clinician Global Impression - Improvement and Severity Scales (CGI)
Time Frame: End of trial
This is a measure of how the treating physician perceives the effectiveness of a drug treatment, and it is typically used in these types of clinical trials.
End of trial
