Pivotal in vivo bioequivalence study comparing two formulations of 21-acetoxyl group-11 beta-hydroxy-6 Alpha-Methyls-17-propiono Oxy-1,4-pregnen diethylene-3,20-diketone fatty ointment applied to the skin in healthy male and female volunteers.
Scientific title
A pivotal in vivo bioequivalence study comparing two formulations of 21-acetoxyl group-11 beta-hydroxy-6 Alpha-Methyls-17-propiono Oxy-1,4-pregnen diethylene-3,20-diketone fatty ointment, using the appropriate dose duration (ED50) calculated from the Pilot dose duration-response study, using healthy male and female volunteers who meet the responder and detector criteria.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A multiple dose study design whereby each participant receives 10 mg (5mg/cm2) per site of the test formulation of 21-acetoxyl group-11 beta-hydroxy-6 Alpha-Methyls-17-propiono Oxy-1,4-pregnen diethylene-3,20-diketone fatty ointment (0.1% w/w) and 10 mg (5mg/cm2) per site of the innovator formulation of 21-acetoxyl group-11 beta-hydroxy-6 Alpha-Methyls-17-propiono Oxy-1,4-pregnen diethylene-3,20-diketone fatty ointment (0.1% w/w). The composition of the test and innovator formulations will be the same except for the excipients of each formulation.

The intervention for this trial is the test formulation of 1 mg/g (0.1% w/w) 21-acetoxyl group-11 beta-hydroxy-6 Alpha-Methyls-17-propiono Oxy-1,4-pregnen diethylene-3,20-diketone fatty ointment

Subjects will be healthy subjects who have shown a vasoconstriction response to a single dose of 21-acetoxyl group-11 beta-hydroxy-6 Alpha-Methyls-17-propiono Oxy-1,4-pregnen diethylene-3,20-diketone fatty Ointment

The test and reference ointment will be applied to pre-allocated sites at times determined from the pilot study results (ACTRN12623000272695).
ED50 (optimal dose duration)
D1 (Shorter dose duration reference listed drug calibrator)
D2 (Longer dose duration reference listed drug calibrator)

The ointment is then removed from all sites 5 hours after the first application 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.

There will be 16 sites in total (8 on each arm whereby 6 sites will be treated with the test or reference cream and 2 sites will be untreated control sites).

All application times will be recorded and checked in individual subjects Case Report Forms.

Ointment is applied by a trained staff member using pre-filled applicators.

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] 334809 0
To compare the in vivo bioequivalence of two formulations of 21-acetoxyl group-11 beta-hydroxy-6 Alpha-Methyls-17-propiono Oxy-1,4-pregnen diethylene-3,20-diketone fatty ointment (as summarised by AUEC (Area Under the Effect Curve)) using vasoconstriction. Blanching will be evaluated objectively using a Minolta CR30 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.
Timepoint [1] 334809 0
Ointment is applied at various times to 6 sites per arm and assessed at each evaluation time of 0, 2, 4, 6, 19 and 24 hours after cream removal.
Secondary outcome [1] 422134 0
Safety of the two formulations will be assessed throughout the study days by observing the skin and asking participants if they are experiencing any side effects.
Timepoint [1] 422134 0
Assessed at each evaluation time of 0, 2, 4, 6, 19 and 24 hours after cream removal.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All formulations will be labelled as Formulation A and B. The identification of each treatment will only be known to the Managing Director and the Section Head - Trials and Regulatory Affairs.

Randomisation will be performed using a randomisation table created by computer software (i.e. computerised sequence generation).
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 which is determined by the order in which the participants give consent, ie the 1st participant to give consent is allocated 001. and a 2 digit subject number which is determined by simple randomisation using a computer generated true random number generator at www.random.org. The screening number will be issued once the participant has given written consent to participate in the study and the two digit subject number will be issued after acceptance into the study.

The Randomization Scheme is computer generated by Zenith and as such, treatment sequences are randomly assigned to each subject number

Other design features
This is a single period, two treatment study where each subject has ointment applied at time points determined by the Pilot Study e.g. receives 2 test and 4 reference doses on each arm as well as 2 blank sites per arm.
