Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
ZYN001 transdermal patch contains 36mg of delta-9 tetrahydrocannabinol (THC). The patch will be applied to the right or left upper arm.

Phase 1: In Periods 1 to 3 qualified participants will be randomized to receive a ZYN001 patch or a placebo patch:
Period 1 – patch worn for 24 hours
Period 2 – patch worn for 3.5 days
Period 3 – patch worn for 7 days

Phase 2 of the study- two groups will receive multiple patch applications. Participants will be randomized to one of two treatment groups as indicated below:
Period 4 – patch worn for 3.5 days, repeated 4 times (4 applications) for a total of 14-days patch wear time.
Period 5 – patch worn for 7 days, repeated two times (2 applications) for a total of 14-days patch wear time.

Outcomes
Primary outcome [1] 302365 0
To evaluate the safety and tolerability of ZYN001.
Assessed by: monitoring physical examinations, examination of skin application site, vital signs, 12-lead ECG, laboratory tests, neuropsychological tests and adverse events throughout the study. Possible adverse events could include- getting dizzy, loss of balance, change in heart rate or blood pressure, red or irritated eyes, feeling tired, pounding in chest or heart, dry mouth, jitters, headache, upset stomach, vomiting, sore throat, increased appetite, trouble concentrating, memory problems, confusion, depression, feeling paranoid, rash, trouble sleeping, blurry vision, ringing in the ears, diarrhea, and hallucinations.
Timepoint [1] 302365 0
Timepoint: Periods 1-5 subjects are confined to the research facility until the patch is removed and then return for PK draws and assessments over an additional 2 weeks at which time they will complete the End of Study Visit unless the skin irritation score is greater than ‘0’ or they test positive for THC. If this is the case, they will return to the research facility until the skin irritation score is equal to ‘0’ and they test negative for THC.

Period 4 subjects are confined for 5 days, return the evening of Day 7 and are confined until Day 9, returning the morning of Day 11 and released on Day 12 then they return for 4 PK draws and assessments over an additional 2 weeks at which time they will complete the End of Study visit unless the skin irritation score is greater than 0 or they test positive for THC. If this is the case they will return to the research facility until the skin irritation score equals 0 and they test negative for THC.

Study assessments are collected for all study periods as follows:
Physical Exam at Screening with a Targeted Physical Exam at Day -1, each day of dosing and EOS Visit

Summary
Brief 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.
