Summary

This study is evaluating the long term and safety and tolerability of ZYN002, a clear gel that can be applied to the skin (called transdermal application) twice a day for treatment of symptoms of Fragile X Syndrome (FXS) Who is it for? Patients who have been diagnosed with Fragile X Syndrome and are aged between 3 and 18 years old who have participated in the ZYN2-CL-016 double-blind study and meet certain eligibility criteria. Study details Eligible participants will undergo up to a 52-week treatment period. Participants who are taking anti-epileptic drugs may undergo an additional 1-2 weeks of treatment to taper off study drug treatment. All participants will be assigned to ZYN002. 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. Participants whose weight changes during the course of the study may have their doses changed at the investigator’s discretion on or after the Month 1 visit, or reduced due to tolerability issues at investigator’s discretion. Blood samples will be collected for safety analysis of ZYN002. 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 and/or with the participant and their parents/caregivers. Participation in this study may help the child’s/ adolescent’s FXS symptoms; however, we cannot guarantee that he/ she will get any benefits from this study. The results of this study may benefit future patients.

Plain Language Summary

Simplified for easier understanding

Fragile X Syndrome (FXS) is the most common inherited cause of intellectual disability and autism. It can cause significant difficulties with learning, behaviour, anxiety, and social interaction. There is currently no approved medication specifically for FXS, which means families often have limited treatment options. This extension study is testing the long-term safety and tolerability of ZYN002, a cannabidiol gel applied directly to the skin twice a day. The study is open only to children and teenagers aged 3–18 who have already completed a related clinical trial (ZYN2-CL-016). Participants continue to receive ZYN002 for up to 52 weeks, with regular assessments, blood tests, and questionnaires completed by parents and caregivers to track how the child is doing and whether the gel is causing any side effects. Your child may be eligible if they have a diagnosis of Fragile X Syndrome, are aged 3–18, and participated in the qualifying prior study without serious adverse events. Children currently taking other experimental treatments or with significantly elevated liver enzymes are not eligible.

ZYN002 is a pharmaceutically manufactured Cannabidiol (CBD) that is developed as a clear gel that can be applied to the skin (called transdermal delivery). The gel will be applied to clean, dry, intact skin of the shoulders and/or upper arms. Only participants from the ZYN2-CL-016 study who meet the inclusion criteria and none of the exclusion criteria for study ZYN2-CL-017 are eligible. Parents/caregivers will apply the study gel twice daily for the 52-week treatment period. Participants who weigh less than or equal to 35 kg, will receive 1 sachet of ZYN002, applied every 12 hours (± 2 hours). Participants who weigh more than 35 kg will receive 2 sachets of ZYN002, applied every 12 hours (± 2 hours). At the Investigator’s discretion, the dose may be increased to a total of 4 sachets a day or decreased to a total of 2 sachets a day any time after the first month of treatment. Participants who are taking Anti-epileptic drugs may have an additional one or two weeks of treatment after the 52 week treatment period to taper off study treatment. Participant compliance with the intervention will be monitored by the study coordinator through drug accountability at each study visit.
