Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, three-treatment, three-period, six-sequence, crossover, bioequivalence design whereby each participant receives the test formulation of 1 x 500 mg paracetamol, 200 mg ibuprofen and 5.1 mg doxylamine succinate immediate release tablet on one occasion and the innovator formulations of 1 x 500 mg paracetamol, 10 mg codeine phosphate hemihydrate and 5.1 mg doxylamine succinate immediate release tablet on one occasion and 1 x 500 mg paracetamol and 200 mg ibuprofen immediate release tablet on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of 500 mg paracetamol, 200 mg ibuprofen and 5.1 mg doxylamine succinate.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose).

Participants are required not to eat for 10 hours prior to dosing. Subjects are required to fast for approximately 4 hours after receiving each dose. Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance and will be monitored for 24 hours.

Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site 10 hours prior to dosing.

Pre and post study laboratory tests will be completed to assess the health of participants.

Each dose will be taken orally with 240 ml of water at ambient temperature. Medication must be swallowed whole and a mouth check will be conducted to ensure the medication has been taken as directed.

Comparator / control treatment
Single dose, three treatment, three period, six sequence, crossover study design whereby each participant receives the test formulation of paracetamol, 200 mg ibuprofen and 5.1 mg doxylamine succinate on one occasion and the innovator formulation of 500 mg paracetamol, 10 mg codeine phosphate hemihydrate and 5.1 mg doxylamine succinate on one occasion and 500 mg paracetamol and 200 mg ibuprofen on one occassion with each dose separated by a one week washout period. The comparator/control for this trial is the innovator formulation of paracetamol, 200 mg ibuprofen and 5.1 mg doxylamine succinate .

Outcomes
Primary outcome [1] 320581 0
This is a composite primary outcome to compare the bioavailability of paracetamol, ibuprofen and doxylamine (as summarised by Cmax and AUC) for all formulations. All plasma samples will be assayed for paracetamol, ibuprofen and doxylamine using one fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines. Codeine phosphate will not be analysed in this study.
Timepoint [1] 320581 0
Prior to dosing and at 10 min, 20 min, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 14, 16, 20, 24, 36 and 48 hours post dosing.
Secondary outcome [1] 372102 0
This is a composite secondary outcome measuring Time to maximum peak concentration (Tmax) for paracetamol, ibuprofen and doxylamine combined in one assay. Tmax will be the time where the maximum concentration occurred in the sample points.
Timepoint [1] 372102 0
Prior to dosing and at 10 min, 20 min, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 14, 16, 20, 24, 36 and 48 hours post dosing.

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, B and C. The identification of each treatment will only be known to the Managing Director and the Section Head - Trials and Regulatory Affairs.

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 subject number (randomisation number) after acceptance into the study
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation list will be prepared using a computer program for a three-way partial replicate crossover design.
Masking / blinding

Summary
Brief summary
The objective of this study is to evaluate the bioequivalence by comparing the rate and extent of absorption of the test formulation, a 500 mg paracetamol / 200 mg ibuprofen / 5.1 mg doxylamine succinate immediate release tablet relative to that of the reference formulations, an immediate release tablet containing 500 mg paracetamol / 10 mg codeine phosphate hemihydrate / 5.1 mg doxylamine succinate and an immediate release tablet containing 500 mg paracetamol / 200 mg ibuprofen following oral administration of a single dose to healthy male and female subjects under fasting conditions.
