Active clinical trials for "Tourette Syndrome"

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.

A joint NIH -Tourette Syndrome Association Conference has emphasized the critical need for the testing and development of new pharmacotherapy for tic suppression in Tourette syndrome (TS). This submission is a safety, tolerability and efficacy pilot study using two medications that modulate glutamate neurotransmission, riluzole, a glutamate antagonist, and D-serine, a glutamate agonist. Glutamate is the primary excitatory neurotransmitter in the central nervous system, an essential component of pathways implicated in TS and an extensive modulator of dopamine, the major neurotransmitter associated with tics. This is a single site, short-term, proof of concept study of riluzole and D-serine for the treatment of tics. Each medication will be evaluated and compared to placebo as part of a double-blind, randomized, parallel, flexible dose, three-arm, 8-week, treatment protocol (D-serine, riluzole, or placebo). A total of sixty patients (age 8-17 years) with TS and moderate to moderately-severe tics will receive study medication according to a 2:1 (dopamine modulating drug: placebo), randomized schedule, i.e., riluzole (n=24), D-serine (n=24), placebo (n=12). The primary outcome measure is tic suppression as determined by changes in the Total Tic Subscore of the Yale Global Tic Severity Scale (YGTSS). Secondary tic outcome measures include changes in the YGTSS Total Score and two Global Impression Scales. Further, since both riluzole and D-serine have been proposed as treatments for obsessive-compulsive behaviors, a TS co-morbidity, these symptoms will be followed. Safety measures include serial physical examinations, vital signs, laboratory studies (comprehensive metabolic panel, complete blood count, plasma amino acids, and urine analyses), documentation of side effects and adverse events, and measurement of changes in ADHD, depression and anxiety. This pilot investigation will provide important proof-of-concept data on glutamate therapies for TS and, in turn, evidence for large-scale, multi-center clinical trials.

This study will compare the efficacy of supportive therapy versus habit-reversal therapy for the treatment of Tourette syndrome and chronic tic disorder.

This study will determine the effectiveness of cognitive behavior therapy (CBT) with habit reversal training (HRT) in treating chronic tic disorders (CTDs) in children and adolescents.

The aim of this study is to evaluate the efficacy and safety of bilateral pallidal stimulation in patients with a severe form of Gilles de la Tourette syndrome.

The purpose of this study is to determine whether deep brain stimulation is effective at reducing tic frequency and severity in adults with Tourette syndrome.

Tourette's syndrome is a disabling neuropsychiatric disorder with major psychosocial consequences in some patients. The pathophysiology is still unknown. Some data suggest an dysfunction of limbic circuits in basal ganglia. The aim of this study is to evaluate the effect of high frequency stimulation of the internal part of the globus pallidus and/or parafascicular-median centre of the thalamus, two structures implicated in the limbic circuit, in patients with severe Tourette's syndrome.

OBJECTIVES: I. Evaluate the presumed mechanism of action of low dose pergolide to act acutely through the dopaminergic autoreceptor or postsynaptically at D2 sites in children 7 to 17 with tourette syndrome (GTS). II. Compare tolerability and safety of pergolide in these patients to standard neuroleptic therapy via naturalist assessment after 3-6 months of treatment using matched historical controls on neuroleptics. III. Determine efficacy of pergolide for tic control in these patients.

Two-part study consisting of a double-blind, randomized, placebo-controlled, study at two target dose levels (Part 1) and an open-label, non-randomized study (Part 2) to determine the efficacy of ABX-1431 in treating adult patients with Tourette syndrome or Chronic Motor Tic Disorder as measured by the change from baseline in Total Tic Score of the Yale Global Tic Severity Scale (YGTSS-TTS) compared with placebo.

This is a study to evaluate the efficacy and safety of deutetrabenazine (TEV-50717) tablets for the reduction of motor and phonic tics associated with TS in children and adolescents 6 through 16 years of age.
