Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Multiple dose study where each participant attends a single treatment session and receives Advantan fatty ointment (methylprednisolone aceponate 1 mg/g (0.1% w/w)) at various dose durations. The intervention for this trial is the Reference Listed Drug (RLD) of Advantan fatty ointment (methylprednisolone aceponate 1 mg/g (0.1% w/w)) .

Subjects will be healthy subjects who have shown a vasoconstriction response to a single dose of Advantan fatty ointment. All applications, measurements and assessments will be carried out at the Zenith Clinical Site where all participants will be confined and monitored for the duration of the study i.e. a 2 day period.

There will be 12 sites in total (6 on each arm) where 4 sites will be treated with the fatty ointment and 2 will be untreated control sites. The 8 treated sites (4 on each arm) will have 10 mg of fatty ointment applied at various dose-durations at 6, 4, 2, 1.5, 1, 0.75, 0.5 and 0.25 hours prior to fatty ointment removal. The fatty ointment is then removed from all sites and the Chromameter measurements for the pharmacodynamic responses of the topical corticosteroid will be carried out at 0, 2, 4, 6, 19 and 24 hours following removal.

Subjects who meet the inclusion and exclusion criteria will be included in this study. Pre and post study laboratory tests will be performed along with an ECG and medical evaluation. A follow up visit will also be completed to assess for safety.

Outcomes
Primary outcome [1] 334024 0
To determine the ED50 parameter of Advantan fatty ointment (methylprednisolone aceponate 0.1%w/w) using the Minolta Chromameter. The values will be used to measure the degree of colour change of each treatment site using a formulation that will be calculated and plotted against time.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each participant will be identified by a 3 digit screening number and a 2 digit subject number. The screening number will be issued once the participant has given written consent to participate in the study and the two digit study number (randomisation number) after acceptance into the study. Randomization will be performed using a randomisation table created by computer software (i.e. computerized sequence generation).

Treatment sites will be randomly allocated for each participant.
Masking / blinding
Open (masking not used)
