This is an investigator-initiated proof of concept study with the purpose to examine the safety, tolerability and feasibility of Dronabinol (synthetic Δ9-THC) and PEA for the treatment of adults with Tourette syndrome.

Tourette Syndrome Drug: Dronabinol and Palmotoyletahnolamide Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Intervention Model Description:

Participants will receive active medications and will be followed-up bi-weekly for 12 weeks.

Masking: No masking
Primary Purpose: Treatment

Official Title: Examining the Efficacy of a Therapeutic Combination of Dronabinol (Synthetic Δ9-tetrahydracannabinol) and Palmitoylethanolamide for Tourette Syndrome

Primary Outcome Measures:

Estimated Enrollment: 18
Actual Study Start Date: February 1, 2017
Estimated Study Completion Date: January 2019
Estimated Primary Completion Date: January 2018 (Final data collection date for primary outcome measure)
Experimental: Dronabinol and Palmitoylethanolamide

Subjects will be titrated up on Dronabinol dose during the first week of the trial (2.5mg Dronabinol for 3 days and then 5mg Dronabinol for 4 days increasing to 10mg Dronabinol for the remainder of the trial). Dronabinol will only be increased to 10mg at the week 1 assessment if the subject is tolerating the 5mg dose of Dronabinol and the Dronabinol may be reduced based on patient side-effects. Subjects will be assigned to receive two 400mg tablets of PEA daily for all 12 weeks.

Drug: Dronabinol and Palmotoyletahnolamide

Subjects will receive Dronabinol which will be slowly titrated in the first week of the study and will receive the PEA a standing dose of 400mg of PEA. They will be followed for a total of 12 weeks.

  • MimyX
  • N-(2-hydroxyethyl)palmitate
  • N-palmitoylethanolamine
  • PeaPure
  • C18H37NO2
  • PEA

We propose a 12-week, investigator-initiated, open-label trial of a therapeutic combination of Dronabinol and PEA in 18 adults with Tourette syndrome. Subjects will receive Dronabinol and PEA in combination for the duration of the trial. Our goal for this pilot study is to (1) provide initial safety, feasibility and tolerability data on both Dronabinol and PEA in a TS population and (2) provide data in order to make a more informed decision regarding the appropriate sample size and design of a larger clinical trial to prove efficacy (i.e. sample size and trial duration in large efficacy trial of the Dronabinol/PEA combination in TS).

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Adult between 18-60 years of age
  • Meet DSM-5 criteria for the diagnosis of Tourette syndrome
  • Significant current tic symptoms: YGTSS total tic score greater than or equal to 22 at baseline
  • On stable psychiatric medication regimen for a minimum of 4 weeks prior to beginning the trial
  • Accepted method of birth control

Exclusion Criteria:

  • Comorbid bipolar disorder, psychotic disorder, substance use disorder, developmental disorder or intellectual disability (IQ<70)

Medication change is defined to include dose changes or medication discontinuation.
  • Recent change in behavioral treatment for Tourette syndrome or comorbid conditions (i.e. OCD) within the last 4 weeks or initiation of behavioral therapy for tics within the last 12 weeks.
  • Taking any co-medications (over the counter or prescription), food supplements/additives which can have a drug interaction with dronabinol or PEA.
  • Positive pregnancy test or drug screening test
  • History of cannabis dependence
  • Significant Medical Comorbidity
  • History of hypersensitivity to any cannabinoid or sesame oil
