|Condition or disease||Intervention/treatment||Phase|
|Fragile X Syndrome||Drug: ZYN002 - CBD Transdermal Gel Other: Placebo Transdermal Gel||Phase 2 Phase 3|
This is a randomized, double-blind, placebo-controlled, multiple-center study, to assess the efficacy and safety of ZYN002, a pharmaceutically manufactured CBD, formulated as a transdermal gel, for the treatment of children and adolescent with FXS. Approximately 204 male and female patients, ages 3 to < 18 years, will undergo a screening process. Eligible participants will be randomized 1:1 to either trial drug or placebo and will undergo a 14-week treatment period. Randomization will be stratified by gender, weight category and geographic region. All participants may receive placebo during the trial. Participants who are taking anti-epileptic drugs may undergo an additional 1-2 weeks of blinded treatment to taper off study drug treatment. The assignment will be done by a computer generated system and neither the study doctor or the participant or their caregivers will know which treatment is being given to them. The dose of the treatment will depend on the weight of the participants. If the participants weigh less than or equal to 35 kg, they will receive 2 sachets of the gel twice a day (1 sachet approximately every 12 hours) and if they weigh more than 35 kg, they will receive 4 sachets of gel per day (2 sachets approximately every 12 hours). Parents/ caregivers will be instructed on proper application of the gel. The gel will be applied to clean, dry, intact skin of the upper arms/ shoulders.
Blood samples will be collected for safety analysis of ZYN002. An independent analytical laboratory will also perform CGG repeat and methylation status analyses. Additionally, the parents/caregivers will be asked to complete some questionnaires. There will be other questionnaires and scales that will be completed at the site by the study doctor.
After the final dose, patients will be followed weekly for 4 weeks by telephone, prior to discharge from the study.

- Aberrant Behavior Checklist-Community, Fragile X Factor Structure (ABC-C FXS) Pre-specified Subscale 3 [ Time Frame: Change from baseline to end of treatment (Week 14) ]The ABC-C is a standard parent/caregiver reported behavioral outcome measure for use in developmental disability clinical trials.
- Clinical Global Impressions- Improvement (CGI-I) [ Time Frame: Change from baseline to end of treatment (Week 14) ]The CGI-I global improvement item is a 7-point Likert scale designed to measure behavioral symptomatic change at a specific time compared to baseline. CGI-I is a standard global measure of potential change with treatment in placebo-controlled pharmacotherapy trials in developmental disabilities.
