Active clinical trials for "Tourette Syndrome"

The primary objective of the proposed study is to evaluate the safety and efficacy of Epidiolex (cannabidiol) in adults with obsessive compulsive and related disorders (OCRDs). Subjects will be treated in an open-label fashion with Epidiolex for two weeks.

This will be a multistate, multicenter clinical study to determine the efficacy and safety of medical cannabis for a wide variety of chronic medical conditions.

Tourette's Syndrome (TS) is characterized by repetitive movements and vocalizations called tics. Due to the suffering caused by TS, children and adolescents often require treatment for their tics. The investigators' research focuses on developing novel repetitive transcranial magnetic stimulation (rTMS) interventions for child and adolescent neuropsychiatric disorders. In this project, the investigators will determine the effect of pairing 3 weeks of rTMS and HRT on tic severity and plasticity as indexed by supplementary motor area (SMA) y-aminobutyric acid (GABA) concentration and functional connectivity of the SMA to the primary motor cortex (M1) in children and adolescents with TS. Children (N = 50, 6-18 years) with TS will be randomized to either a (1) rTMS+HRT arm, or (2) sham rTMS+HRT. Outcome measures will examine tic severity (primary), brain chemistry and function (secondary) at baseline and then at week 7. The investigators' proposed aims are: (Aim 1) To determine the effect of paired rTMS and HRT on tic severity as measured by the Yale Global Tic Severity Scale (YGTSS) by comparing it to sham rTMS + HRT. 1-1: The investigators hypothesize that tic severity will decrease from baseline to post-treatment. 1-2: The investigators also hypothesize that the reduction in tic severity will be greater in the paired treatment group (rTMS+HRT > Sham rTMS+HRT). (Aim 2) To determine the effect of paired rTMS and HRT on brain plasticity compared to sham rTMS + HRT. 2-1: The investigators hypothesize that patients treated with the paired rTMS and HRT will have a greater increase in GABA concentration comparted to sham and HRT. 2-2: The investigators also hypothesize that functional connectivity between the SMA and M1 will be greater with paired treatment (rTMS+HRT > Sham rTMS+HRT).

This Phase 3 multicenter study evaluates the maintenance of efficacy, safety and tolerability of ecopipam tablets in children, adolescents and adults in the treatment of Tourette's Disorder (TD). The study includes an open-label period followed by double-blind, placebo-controlled, randomized withdrawal period.

This research is being performed to try to understand if the use of deep brain stimulation or DBS can treat the symptoms of Tourette syndrome that do not respond well to current medications. In order to do this the investigators will place small stimulation leads on both sides of the brain in a region (a portion of the thalamus) that may alter the abnormal activity in the brain contributing to the symptoms of Tourette syndrome. This requires two surgical procedures, and several preoperative and postoperative visits for tuning the stimulation parameters and recording stimulation effects. The FDA has not approved DBS for use in people with Tourette syndrome, and Medtronic (the manufacturer of the device) has not conducted testing for the system in Tourette syndrome. Therefore its use in this study is experimental.

This pilot study will investigate the clinical and neurophysiological effects of repetitive transcranial magnetic stimulation (rTMS) followed by comprehensive behavioral intervention for tics (CBIT) in adult patients with Tourette's Syndrome (TS). Two groups of moderate disease severity will be randomized to receive active or sham rTMS targeted to the supplementary motor area (SMA) followed by eight CBIT sessions. The change in tic frequency and severity (primary outcome) and neurophysiological changes (secondary outcome) will be compared between the two groups. The central hypothesis is that low frequency rTMS will augment the effects of CBIT through favorable priming of the SMA network.

The purpose of this pilot study is to evaluate the effects of Atomoxetine, a selective noradrenaline reuptake inhibitor, on impulsivity in patients with Tourette's syndrome.

The primary objective of this study is to evaluate the long-term safety and tolerability of ecopipam tablets in children (greater than or equal to [>=] 6 and less than [<] 12 years of age), adolescents (>=12 and <18 years of age), and adults (>=18 years of age) with Tourette's Syndrome (TS).

Although behavior therapy is recognized as a first-line intervention for Tourette's Disorder (TD), less than 40% of adults with TD respond to this evidence-based treatment. Limited tolerance for aversive premonitory urges and affective states that accompany tics may be one likely factor that impedes behavior therapy outcomes. This study examines the relationship between distress tolerance and tic inhibition among adults with TD, and investigates the mechanism and effect of therapeutic skills training to enhance distress tolerance abilities. Findings will determine the optimal approach to enhance distress tolerance among adults with TD and ultimately lead to better behavior therapy outcomes.

The study will examine whether combining Comprehensive Behavioral Intervention for Tics (CBIT) with inhibition of the supplementary motor area (SMA) using transcranial magnetic stimulation (TMS) normalizes activity in the SMA-connected circuits, improves tic suppression ability, and enhances CBIT outcomes in young people with tic disorder. The study will also examine different TMS dosing strategies.
