Description of intervention(s) / exposure
Single dose, four-way fully replicated crossover study whereby each participant receives the test formulation of (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid, 1 x 25 mg capsule on two occasions and the innovator formulation of (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid, 1 x 25 mg capsule on two occasions with each dose separated by a four week washout period. The intervention for this trial is the test formulation of (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid.

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

Participants are required not to eat for 10 hours prior to dosing and to fast for approximately 4 hours after each dose.

Bathroom visits will be supervised to ensure no unauthorized water or food intake and for personal safety.

Participants will be confined at the Clinical Site for 12 hours prior to dosing to ensure compliance and for 24 hours after dosing.

Participants will be monitored for adverse events throughout the study.

Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing and drugs of abuse testing will be performed upon each participant reporting to the Clinical Site 12 hours prior to dosing.

Pre and post study laboratory tests will be completed to assess the health of the 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 that the medication has been taken as directed.

Outcomes
Primary outcome [1] 326612 0
To evaluate the pharmacokinetics (as summarised by Cmax and AUC) of the test formulation relative to that of the reference formulation. All plasma samples will be assayed for (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid using one fully validated LC/MS/MS method. Validation will be conducted to comply with FDA guidelines.

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 labeled as Formulation A and B. Treatments will be allocated randomly.
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).
