Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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.

Outcomes
Primary outcome [1] 308017 0
To evaluate the long-term safety and tolerability of ZYN002.
Safety assessments will include collection of any adverse events, physical and neurological exams (including Tanner staging), clinical laboratory safety assessments (hematology, chemistry and urinalysis), vital signs and 12-lead ECGs. Finally, as the study drug is delivered transdermally, tolerability to study drug application will be assessed through skin check examinations performed at each visit after treatment with study gel has been initiated.
Timepoint [1] 308017 0
Safety and tolerability will be assessed at every study visit from Day 1 to end of treatment, including Day 1, Months 1, 3, 6, 9 and 12, any Unscheduled Visits and the taper period.
