Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study will comprise 2 dosing periods of 12 participants. In the first period, 6 participants will be randomised to receive one dose of 150mg (3x50mg) EMD-RX5 CBD capsules. The other 6 participants will be randomised to receive one 150mg dose of Epidyolex oil. During this time PK and safety assessments will be made.

Following a washout period of 5-7 days, participants will return to the site for their second and final dosing period.

During the second dosing period, participants that received the Epidyolex oil in the first dosing period will receive EMD-RX5 CBD capsules and those that received the capsule in the first dosing period will receive the oil in the second dosing period. PK assessments will be taken up to 24 hours after the study drug administration in each dosing period. Adherence to the dosing regime will be monitored through one-on-one supervised dosing.

Treatment: Drugs
Comparator / control treatment
Epidyolex oil 100mg/mL is used as the comparator treatment for this study. A single 150mg dose of the oil will be administered.

Outcomes
Primary outcome [1] 330657 0
Describe the pharmacokinetic parameters of EMD-RX5 CBD 50mg capsules after a once daily administration of 150mg
Timepoint [1] 330657 0
Plasma CBD PK parameters Cmax; Tmax; AUC0-24hr; AUCinf; T1/2 at the following times: pre-dose, 30 mins, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 8 hours, 12 hours and 24 hours post dose.
Secondary outcome [1] 407100 0
To compare the pharmacokinetic parameters of EMD-RX5 CBD 50mg capsules after a single dose of 150mg to a single 150mg dose of CBD oil
Timepoint [1] 407100 0
Comparison of plasma CBD PK parameters Cmax; Tmax; AUC0-24hr; AUCinf; T1/2 of 150mg CBD capsules and 150mg CBD dose in oil at the following times: pre-dose, 30 mins, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 8 hours, 12 hours and 24 hours post dose.
Secondary outcome [2] 407101 0
To evaluate the safety and tolerability of EMD-RX5 CBD 50mg capsules as assessed together by standard clinical and laboratory measures.

Examples of possible adverse events are: sleepiness, allergic reaction, injury to cells in the liver.

Clinical assessments will include: heart rate assessed by digital heart rate monitor, temperature assessed using infrared thermometer, blood pressure assessed by digital sphygmomanometer.

Laboratory measures (blood tests) will also be used to assess safety, including liver function tests, kidney function tests and full blood count tests (red blood cells, white blood cells and platelet cells).
Timepoint [2] 407101 0
Comparison of adverse events (AEs) during the treatment and post-treatment periods. Adverse events will be monitored daily from the day of the first dose through to 7 days after the final dose. Clinical measures will be assessed prior to the first dose, 24 hours post-first dose, prior to the second dose and 24 hours post-second dose.

Statistical methods / analysis
The analysis of the relative bioavailability between the two different formulations (EMD-RX5 capsule as test and Epidyolex oil as reference) will be based on the dose-dependent plasma CBD parameters AUCinf, AUC0-24hr and Cmax. The natural log-transformed parameters will be analysed separately using a mixed effect model (data permitting) with the treatment group (formulation), sequence and period as fixed effects and subject nested within sequence as a random effect. The geometric means (exponentiated least squares means) and the associated 90% confidence intervals for each treatment group and the geometric mean ratio (exponentiated difference between EMD-RX5 capsule least-squares mean as test and Epidyolex oil least-squares mean as reference) and the associated 90% confidence interval will be presented. The geometric mean ratios and the associated confidence intervals will be expressed as percentages.

Bioequivalence will be concluded if the 2-sided 90% CI is completely contained within the interval (0.80, 1.25). The within- and between-subject variability of both treatments will also be estimated directly from the model for all AUC parameters and Cmax.

The analysis will also be repeated based on the dose-normalised AUCinf, AUC0-24hr and Cmax results.

Tmax will be analyzed nonparametrically using the Wilcoxon signed rank test.

Safety will be assessed by summarising adverse events and clinical laboratory tests. Adverse events will be listed and summarised by system organ class and preferred terms per treatment group. Vital signs and clinical laboratory tests will be tabulated and summarised per treatment group. Adverse event severity will be graded according to the CTCAE grading criteria (CTCAE version 5.0).
