SCI-110 in the Treatment of Tourette Syndrome
Sponsor:

SciSparc

Brief Summary:

To evaluate the efficacy, safety and tolerability of the cannabinoid-based medication SCI-110 compared to placebo in subjects with Tourette syndrome.

Condition or disease

Tourette Syndrome

Intervention/treatment

SCI-110

Placebo

Phase

Phase 2

Detailed Description:

It is believed that SCI-110 will be a valuable treatment option, especially for t those subjects with TS, who do not benefit from or do not tolerate first-line treatment with antipsychotics. Since there is evidence that currently available CBM improves not only tics, but also psychiatric comorbidities, SCI-110 might be even more beneficial to improve a broader spectrum of symptoms resulting in both improved quality of life and decreased disease related costs. Moreover, PEA was shown to minimize AEs associated with cannabinoids use and to reduce their required effective dose (data not published). Hence, the use of SCI-110 is expected to show a therapeutic effect superior to currently available CBMs. It can be assumed that AEs in TS subjects do not differ from AEs described in other groups of subjects treated with medicinal cannabis and/or cannabinoids. In general, cannabinoids are considered as well tolerated.}}

    • Male subjects must be willing to use a condom with sexual partners during this study and for a period of three months following the last administration of study medication until the follow-up visit. Male subjects must be willing to abstain from sperm donation for 3 months after the completion of this study
