Summary

What is this study about? The purpose of this study is to investigate how safe and tolerable a single dose (worn for 24 hrs, 3.5 days or 7 days) and repeat doses (worn for 14 days) of ZYN001 transdermal delivery system is in healthy volunteers. The study will look at how the body absorbs, distributes, breaks down and then removes the study drug from your body. This will be done by analysing the levels of ZYN001 in your blood and urine at various times following drug administration. Your skin at the application sites will be checked to see if there is any irritation or reactions present when the ZYN001 patch is removed. The study will also investigate if ZYN001 affects your brain functioning by administering a number of neuropsychological tests. Who is if for? You may be eligible to join this study if you are aged between 18 and 55 years and are in good health. Study details: This study will investigate different formulation of patches containing ZYN001 compared to a placebo patch (a treatment with no active ingredients which looks like the real thing but it is not). This study is ‘double-blind’ which means you and your study doctor, together with the study staff administering the study treatment will not know whether you are receiving ZYN001 or a placebo patch. What does study participation involve? Initially, the study will investigate four (4) different patches in each study period. All patches will have the same amount of THC drug within a study period but the ingredients in the patches will be different. You will report to the clinic the day before receiving treatment (Day -1). You will participate in either: • Period 1 - one patch worn for 24 hours • Period 2 - one patch worn for 3.5 days • Period 3 - one patch worn for 7 days OR, you will participate in either: Period 4 - one patch applied and worn for 3.5 days, removed and patch #2 applied and worn for 3.5 days, removed and patch #3 applied and worn for 3.5 days, removed and patch #4 applied and removed 3.5 days later Period 5 - one patch applied and worn for 7 days, removed and patch #2 applied and worn for 7 days You will receive application of ZYN001 or a placebo patch. The patch will be applied to either your left or right upper arm. Throughout the study you will have various medical tests (physical examinations, vital signs measured, ECG measured, neuropsychological tests) and will have several blood and urine samples collected for laboratory analysis.
