This phase 2, randomized, double blind 12-week treatment trial of Cannabidivarin (CBDV) will assess the affect of CBDV on behavior in people with PWS.
The study is recruiting 26 patients ages 5 to 30 years with PWS and will take place at the Montefiore Medical Center in Bronx, NY.

Study Type: Randomized, double-blind, placebo-controlled
Eligible Ages: 5 to 30 years
Trial Id: NCT03848481
Duration: 12 weeks
Status: opening soon
Lead Sponsor: Montefiore Medical Center
Countries: United States
- Male or Female child outpatients aged 5 to 30 years.
- Diagnosis of PWS confirmed by genetic testing and patient medical records and history.
- Stable pharmacologic, educational, behavioral and/or dietary interventions for 4 weeks prior to the study start, and for the duration of the study.
- Have a physical exam and laboratory results that are within the norms for PWS5. Presence of a parent/caregiver/guardian that is able to consent for their participation and complete assessments regarding the child's development and behavior throughout the study. Child Assent will be obtained if the subject is 7 years of age or older and has the mental capacity to understand and sign a written assent form and/or give verbal assent.
- Score on the Clinical Global Impression Scale Severity (CGI-S) ≥ 4 (moderate severity) at baseline.
- Score of ≥18 on the Aberrant Behavior Checklist-Irritability (ABC-I) at baseline.
- Agree not to drive or operate machinery.
- Exposure to any investigational agent in the 30 days prior to randomization.
- Prior chronic treatment with CBD, CBDV or an endo-cannabinoid treatment.
- Positive testing for THC or other drugs of abuse via urine testing at the screening visit or baseline visits upon repeat confirmation testing.
- Lifetime history of drug abuse including marijuana/cannabis use.
- A primary psychiatric diagnosis other than PWS, including bipolar disorder, psychosis, schizophrenia, PTSD or MDD. These patients will be excluded due to potential confounding results.
- A medical condition that severely impacts the subject's ability to participate in the study, interferes with the conduct of the study, confounds interpretation of study results or endangers the subject's well-being (including but not limited to hepatic or renal impairment and cardiovascular disease).
- Known or suspected allergy to CBDV or excipients used in the formulation (i.e. sesame).
- Renal, pancreatic, or hematologic dysfunction as evidenced by values above upper limits of normal for BUN/creatinine, or values twice the upper limit of normal for serum lipase and amylase, platelets <80,000 /mcL, or WBC<3.0 103 /mcL.
- Liver dysfunction manifested by > 3 X UNL values of AST or ALT
- ECG abnormality at baseline screening or clinically significant postural drop in systolic blood pressure at screening. If the initial screening ECG shows a QTcB of greater than 460 msec, then 2 additional ECGs will be conducted in the same sitting, 5 minutes apart. If not recognized at screening, then a full triplicate repeat showing an average QTcB of 460 msec or less to meet all inclusion/exclusion criteria
- Female subjects who are pregnant will be excluded from the study. If a female subject is able to become pregnant, she will be given a serum pregnancy test before entry into the study. Female subjects will be informed not become pregnant while taking CBDV.
