Description of intervention(s) / exposure
A total of 42 eligible subjects will be randomized in 1:1:1:1:1:1:1 ratio to one of the seven treatment cohorts. Then within a cohort, a subject will be further randomized in 2:1 ratio to receive either ZYN002 or placebo. Therefore, six eligible unique subjects will be randomized to a treatment cohort. Within a treatment cohort, four subjects will be randomized to receive ZYN002 and two subjects will be randomized to receive placebo. Participants will be randomised to one of seven treatment groups as indicated below.
Treatment A – 10 g of 2.5% ZYN002 or placebo applied twice daily (AM and PM) to right and left upper arms/shoulders (Total active daily dose 500mg)
Treatment B – 10 g of 2.5% ZYN002 or placebo applied twice daily (AM and PM) to right and left upper thighs (Total active daily dose 500mg)
Treatment C – 10 g of 2.5% ZYN002 or placebo applied twice daily on right and left upper arms/shoulders AM and right and left upper thighs (PM) (Total active daily dose 500mg)
Treatment D – 6 g of 4.2% ZYN002 or placebo applied twice daily (AM and PM) to right and left upper arms/shoulders (Total active daily dose 504mg)

Treatment E – 6 g of 4.2% ZYN002 or placebo applied twice daily on right and left upper arms/shoulders AM and right and left upper thighs (PM) (Total active daily dose 504mg)
Treatment F – 4.7 g of 4.2% ZYN002 or placebo applied twice daily (AM and PM) to right and left upper arms/shoulders (Total active daily dose 394.8mg)
Treatment G – 4.7 g of 4.2% ZYN002 or placebo applied twice daily on right and left upper arms/shoulders AM and right and left upper thighs (PM) (Total active daily dose 394.8mg)
Participants will receive the same number of treatments of placebo gel as the number of active study drug in order to keep the study blinded.
The gel will be thoroughly massaged into right and left upper arms/shoulders or right and left upper thighs by the participant. Once the participant has completed their treatment application they will be instructed to wash their hands thoroughly with soap and water to remove any residual gel. Participants will be instructed to not lay or lean on either shoulder/arm, for at least 30 minutes post dosing/ Subjects will be permitted to shower more than 90 minutes prior to each morning’s dosing.. Dosing period will be 13 days plus one morning dose on day 14. Adherence to treatment will be monitored by empty gel syringe return and collection and review of participant dosing diary.

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 will be blinded to which treatment the participant is receiving. 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 the first randomization number for the participant. 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 will be prepared by a statistician. The software application SAS will be used to generate the randomization codes. A series unique codes will be issued on a per protocol treatment cohort allocation. On Day 1 eligible healthy subjects will be randomized to one of the seven treatment cohorts receiving randomized treatment twice daily. Subjects in each treatment cohort will be randomized to receive either active treatment or placebo in a 2:1 ratio.

Statistical methods / analysis
Pharmacokinetics: PK parameters listed above for ZYN002 (CBD) and THC will be calculated/derived from the data using non-compartmental analysis with WinNonlin. Actual sampling times and actual dose will be used to estimate plasma PK parameters. 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 by treatment group and time point. Differences in dose-dependent PK parameters (Cmax,ss, Cmin,ss, Cav,ss, AUC) between Treatments (A-G) will be compared via an Analysis of Variance (ANOVA) model or an appropriate non-parametric approach.
The pre-dose Ctrough plasma levels over the days of dosing will be compared statistically for assessment of steady-state for each ZYN002 dose level. Attainment of steady-state will be concluded if the 90% CI for the geometric mean ratio between two consecutive time points (i.e. Day 10 vs. Day 8) is completed within the acceptance range of (0.80 – 1.25).
Safety Analyses: All subjects who receive at least one dose of study drug will be included in the safety analysis.
AEs will be classified by system organ class and preferred term using the MedDRA version 19.0 or higher. AEs and SAEs will be tabulated by treatment group. Additionally, the total number of AEs and the total number of subjects with AEs will be identified for each treatment.
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. ECGs, safety laboratory test results and change from baseline will also be tabulated by treatment group. 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.
