NCT ID: NCT03058562 Completed - Tourette Syndrome Clinical Trials

A Study to Evaluate the Effects of ABX-1431 on Patients With Tourette Syndrome

Start date: February 1, 2017
Phase: Phase 1
Study type: Interventional

The study will investigate the effects and the safety of a single-dose of ABX-1431 HCl on tics and other symptoms of Tourette Syndrome. During part 1 (periods 1 and 2) each patient will receive study drug once and placebo once. Patients who complete part 1 with adequate clinical safety will be offered the option to participate in part 2 (periods 3 and 4) and again willl receive study drug once and placebo once where, in contrast to part 1, administration will take place with a standard high fat meal.

NCT ID: NCT02205918 Completed - Tourette's Syndrome Clinical Trials

Brain-Behavior Interactions in Tic Suppression

Start date: July 1, 2017
Phase:
Study type: Observational

The purpose of this study is to examine how the brain and environment interact to influence children's ability to suppress tics using a medical technology called Transcranial Magnetic Stimulation (TMS).

NCT ID: NCT00026000 Completed - Tourette's Syndrome Clinical Trials

Brain Activation in Vocal and Motor Tics

Start date: November 2001
Phase: N/A
Study type: Observational

This study will investigate the brain areas that are activated by vocal and motor tics in patients with Tourette's syndrome and other tic disorders. Tics are involuntary repetitive movements similar to voluntary movements. They may be simple, involving only a few muscles or simple sounds, or complex, involving several groups of muscles in orchestrated bouts. This study will involve only simple motor tics, such as eye blinking, nose wrinkling, facial grimacing and abdominal tensing, and simple vocal tics, such as throat clearing, sniffing and snorting. Healthy normal volunteers and patients between 14 and 65 years of age with simple motor or vocal tics may be eligible for this study. Participants will have a brief medical history and physical examination and magnetic resonance imaging (MRI) of the brain. MRI uses a magnetic field and radio waves to produce images. For the procedure, the subject lies on a table that is moved into a cylindrical chamber containing a strong magnet. Earplugs are worn to muffle the loud thumping sounds made by electrical switching of the radio frequency circuits and protect against temporary hearing impairment. During the scan, normal volunteers will be asked to make simple movements or sounds designed to imitate tics, such as raising eyebrows, blinking or coughing. Patients with tic disorders will have two parts to the scanning session. First they will relax and allow tics to occur spontaneously, then they will be asked to imitate a specific tic when there is no urge to tic. Patients and healthy subjects will have electromyography (EMG) to record the timing of the voluntary movements and tics. For this procedure, several pairs of small, saucer-like electrodes are attached to the skin with a gel or paste. Electric signals from the electrodes are amplified and recorded on a computer. A microphone may be placed near patients to record any vocal tics. A video camera may also be used to record the tics.
