Study type
Interventional
Description of intervention(s) / exposure
During the first part of the study with 32 healthy volunteers, participants will be randomised to one of five treatment groups as indicated below.
- Treatment A: 5 g of 1% ZYN002
- Treatment B: 10 g of 1% ZYN002
- Treatment C: 5 g of 2.5% ZYN002
- Treatment D: 10 g of 2.5% ZYN002
- Treatment E: 5 g or 10g of placebo
During the second part of the study with 12 patients diagnosed with epilepsy, will receive the highest tolerated dose (Treatment A, B, C or D) from the first part of study or placebo.
ZYN002 or placebo gel will be applied to the skin on the right or left shoulder and/or upper arm as a single application.
The gel will be thoroughly massaged into the shoulders and/or upper arms by a member of the research facility. Participants will not be permitted to wash their shoulder and/or upper arm (application site) for at least 12 hours after application.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The trial site will receive a list of randomization numbers to be used in the study but the list of numbers will not denote which treatment the participant is receiving.

The trial site Pharmacist will be in possession of a sealed opaque envelope. The outside of each of the envelopes will be labelled with the randomization number. Inside the envelope will be the randomization sequence assigned to the specific randomization number. A sealed envelope will only be opened by the site if the blind is required to be broken.

The trial site will screen and enroll subjects that meet the study criteria. Once it is determined the subject/patient qualifies to participate in the study the site will choose from the randomization list the first randomization number for the participant. The randomization list does not denote the treatment the participant is receiving. The site will continue to use the next randomization number in the sequence provided for each subsequent subject enrolled, until they have randomized the appropriate number of subjects for the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomization schedule has been prepared by a statistician. The software application SAS was used to generate the randomization codes. A series unique codes have been issued on a per protocol allocation ratio of 3:1.

Statistical methods / analysis
Pharmacokinetics: Descriptive statistics (arithmetic mean, median, standard deviation, minimum, maximum, coefficient of variation, geometric mean) for the individual PK parameters and plasma concentration over time will be presented. Actual sampling times will be used to estimate plasma PK parameters.
Neuropsychological Tests: Neuropsychological parameters will be summarized for each treatment period and time point using descriptive statistics (number of subjects, mean, standard deviation [SD], median, minimum, and maximum).
Safety Analyses: AEs will be tabulated and classified by system organ class and preferred term using the Medical Dictionary for Regulatory Affairs (MedDRA).
Vital signs collected by time point will be summarized using descriptive statistics and presented by treatment. Changes from baseline in the vital signs will also be summarized by treatment. Safety laboratory tests results and change from baseline will also be tabulated by treatment group. Pulse oximetry measured over the 24-hour treatment period will be summarized by treatment. Application site irritation will be summarized using counts and percentages for each treatment and time point.
Sample size for the study is chosen for the purpose of the study. No formal statistical assumptions are used to determine the sample size.
