Internet-delivered Behaviour Therapy for Children and Adolescents With Tourette's Disorder
Tourette's DisorderPersistent (Chronic) Motor or Vocal Tic DisorderThe purpose of this trial is to evaluate the clinical efficacy, 12-month durability, and cost-effectiveness of BIP TIC - a therapist-guided and parent-guided internet-delivered behavioural intervention for children and adolescents with Tourette's Disorder and Persistent (Chronic) Motor or Vocal Tic Disorder.
Investigations of the Pathophysiology of Gilles de la Tourette Syndrome. Part 1: Simultaneous PET...
Gilles de la Tourette SyndromeTourette SyndromeGilles de la Tourette syndrome (GTS; also known as Tourette syndrome) is a congenital neuropsychiatric disorder. Characteristic symptoms are so-called tics-rapid, repetitive movements (motor tics) or vocalizations (vocal tics) that start suddenly without any apparent purpose. Previous research supports the hypothesis of defective regulation (dysregulation) of the dopaminergic system, with particular discussion of dysfunction of tonic/phasic dopamine release or dopaminergic hyperinnervation. Moreover, given the complex interaction of different neurotransmitters, especially in the basal ganglia, it can be assumed that abnormal dopaminergic transmission also affects other transmitter systems, such as glutamate (Glu) or γ-aminobutyrate (GABA). Furthermore, recent results suggest an abnormality in cerebral iron metabolism in GTS. Since iron is accumulated in dopamine vesicles and plays a central role in dopamine synthesis, this observation may also be related to dysfunction of the dopaminergic system. Therefore, in this multimodal study, the investigators aim to combine positron emission tomography (PET), magnetic resonance imaging (MRI), and magnetic resonance spectroscopy (MRS) methods comparing patients with GTS and a control cohort. In Part 1 of this study, MRI and MRS at 3 Tesla are employed to investigate (i) the binding potential of D1 dopamine receptors, (ii) the concentrations of Glu, glutamine and GABA in the corpus striatum and the cortex cingularis anterior and (iii) the subcortical iron concentration.
A Study to Explore the Effect of Sepranolone in Tourette Syndrome
Tourette SyndromeTourette Syndrome in AdolescenceThe study was an open-label, randomized, multicenter, parallel, Phase 2a study in adolescents and adult patients with Tourette syndrome that aimed to explore the efficacy of Sepranolone as a treatment for Tourette syndrome, by reducing the severity and frequency of tics. The total study duration from the Screening Visit to the final follow-up visit was approximately 26 weeks and included the following periods: A baseline period of 4 weeks between the screening visit (Visit 1) and randomization (4 weeks of baseline period were not needed in well-known adult subjects with stable Tourette syndrome history over the past at least 4 weeks). A school holiday/annual leave period of 2-6 weeks where no study-related activities were done. A randomized treatment period of 12 weeks A safety follow-up period of 4 weeks
Safety and Efficacy Study of NBI-98854 in Adults With Tourette Syndrome
Tourette SyndromePhase 2, double-blind, placebo-controlled study to assess the safety and efficacy of NBI-98854 administered once daily (qd) for a total of 8 weeks of treatment. This study will enroll approximately 90 male and female subjects clinically diagnosed with Tourette Syndrome.

Tourette SyndromeThis is a Phase 2b, randomized, double-blind, placebo-controlled, dose-optimization study to evaluate the efficacy, safety, and tolerability of NBI-98854 titrated to the subject's optimal dose administered once daily (qd) for a total of 12 weeks of treatment in pediatric subjects with TS.
Online Remote Behavioural Intervention for Tics (ORBIT)
Tic DisordersTourette SyndromeOnline Remote Behavioural Intervention for Tics (ORBIT). Primary objective: to evaluate the clinical effectiveness of BiP Tic, a therapist-guided, parent-assisted, internet-based behavioural therapy intervention for tics in young people, compared with usual care plus online education. Secondary objectives include 1) optimising the design of the intervention, 2) undertaking an internal pilot, 3) evaluating cost effectiveness and 4) longer term impact, and 5) identifying barriers to implementation.
