Description of intervention(s) / exposure
Single centre, open-label, single application study in a total of 12 healthy participants.

Eligible participants will receive a single application (3 day, 72 hour application time) of a transdermal oxymorphone patch (containing 19.2 mg oxymorphone) with a subsequent 4 day washout period. The total duration of the intervention is 7 days.

Outcomes
Primary outcome [1] 288633 0
To characterise the pharmacokinetic profile of oxymorphone delivered transdermally using the oxymorphone patch, assessed through collection of blood samples.
Timepoint [1] 288633 0
Pharmacokinetic profile will be assessed through collection of blood samples at various time points. On Day 1 there will be an intensive blood sampling period in which samples will be collected every 1-2hrs and for the duration of the in-house period sample will be collected every 4-8hrs. A total of 43 blood samples will be collected from each participant and analysed.
Secondary outcome [1] 300665 0
To evaluate the safety/tolerability of oxymorphone delivered transdermally from the oxymorphone patch.

Safety/tolerability will be assessed by:
* The frequency of Adverse Events
* The frequency of skin irritation at site
* Clinically important changes in Vital signs from baseline
* Clinically important changes in ECG measurements from baseline
* Clinically laboratory tests and assessments
Timepoint [1] 300665 0
Safety/tolerability will be assessed by:
* The frequency of Adverse Events measured daily throughout the duration of the stuy
* The frequency of skin irritation measured after removal of the patch
* Clinically important changes in Vital signs from baseline, measured 4 hourly throughout the in-house period
* Clinically important changes in ECG measurements from baseline, measured 6 - 12 hourly throughout the in-house period
* Clinically laboratory tests and assessments measured at baseline, day 4, discharge and f/up

* Evidence or history of substance or alcohol abuse (drink more than 2 standard units of alcohol per day), including positive test results for drugs of abuse in the urine or a positive alcohol breath test at Screening or at Check-In.
* Unwilling or unable to abstain from recreational drug/substance use, alcohol, caffeine or other xanthine-containing products from Day -1 until discharge.
