CANNA-TICS: Efficacy and safety of oral treatment with nabiximols in adults with chronic tic disorders - Results of a prospective, multicenter, randomized, double-blind, placebo controlled, phase IIIb superiority study.
Preliminary data suggest that cannabis-based medicines might be a promising new treatment for patients with Tourette syndrome (TS)/chronic tic disorders (CTD) resulting in an improvement of tics, comorbidities, and quality of life. This randomized, multicenter, placebo-controlled, phase IIIb study aimed to examine efficacy and safety of the cannabis extract nabiximols in adults with TS/CTD (n = 97, randomized 2:1 to nabiximols:placebo). The primary efficacy endpoint was defined as a tic reduction of ≥ 25% according to the Total Tic Score of the Yale Global Tic Severity Scale after 13 weeks of treatment. Although a much larger number of patients in the nabiximols compared to the placebo group (14/64 (21·9%) vs. 3/33 (9·1%)) met the responder criterion, superiority of nabiximols could formally not be demonstrated. In secondary analyses, substantial trends for improvements of tics, depression, and quality of life were observed. Additionally exploratory subgroup analyses revealed an improvement of tics in particular in males, patients with more severe tics, and patients with comorbid attention deficit/hyperactivity disorder suggesting that these subgroups may benefit better from treatment with cannabis-based medication. There were no relevant safety issues. Our data further support the role of cannabinoids in the treatment of patients with chronic tic disorders.

Potential impact of COVID-19 on ongoing clinical trials: a simulation study with the neurological Yale Global Tic Severity Scale based on the CANNA-TICS study.
The COVID-19 pandemic has manifold impacts on clinical trials. In response, drug regulatory agencies and public health bodies have issued guidance on how to assess potential impacts on ongoing clinical trials and stress the importance of a risk-assessment as a pre-requisite for modifications to the clinical trial conduct. This article presents a simulation study to assess the impact on the power of an ongoing clinical trial without the need to unblind trial data and compromise trial integrity. In the context of the CANNA-TICS trial, investigating the effect of nabiximols on reducing the total tic score of the Yale Global Tic Severity Scale (YGTSS-TTS) in patients with chronic tic disorders and Tourette syndrome, the impact of the two COVID-19 related intercurrent events handled by a treatment policy strategy is investigated using a multiplicative and additive data generating model. The empirical power is examined for the analysis of the YGTSS-TTS as a continuous and dichotomized endpoint using analysis techniques adjusted and unadjusted for the occurrence of the intercurrent event. In the investigated scenarios, the simulation studies showed that substantial power losses are possible, potentially making sample size increases necessary to retain sufficient power. However, we were also able to identify scenarios with only limited loss of power. By adjusting for the occurrence of the intercurrent event, the power loss could be diminished to different degrees in most scenarios. In summary, the presented risk assessment approach may support decisions on trial modifications like sample size increases, while maintaining trial integrity.

Tic Reduction in Adult Onset Gilles De La Tourette Syndrome Using as Required Nabiximols Spray.
Tourette syndrome (TS) manifests with motor and vocal tics that can reach disabling intensity. Established therapies may show insufficient relief or side effects. Cannabinoids have demonstrated therapeutic potential in small studies. This report presents buccal Nabiximols "as required" in the treatment of tics in TS.. A 25-year-old man presented with stigmatizing motor and phonic tics after cessation of daily Cannabis use. After Tiaprid 300 mg per day had shown no sufficient effect a trial of Nabiximols reduced tics by >90%.. Nabiximols could be an adjunct treatment in TS for situations were tics are severly disabling.

Severe motor and vocal tics controlled with Sativex®.
A single case report on cannabinoid treatment for treatment-resistant Tourette syndrome (TS).. Our subject received 10.8 mg Tetrahydocannabinol and 10 mg cannabidiol daily, in the form of two oro-mucosal sprays of 'Sativex. Both subjective and objective measures demonstrated marked improvement in the frequency and severity of motor and vocal tics post-treatment. There was good interrater reliability of results.. Our results support previous research suggesting that cannabinoids are a safe and effective treatment for TS and should be considered in treatment-resistant cases. Further studies are needed to substantiate our findings.
