Health condition
Health condition(s) or problem(s) studied:
(2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid capsules are indicated for the induction of remission in patients with acute promyelocytic leukemia (APL), French-American-British (FAB) classification M3 (including the M3 variant), characterized by the presence of the t(15;17) translocation and/or the presence of the PML/RARa gene who are refractory to, or who have relapsed from, anthracycline chemotherapy, or for whom anthracycline-based chemotherapy is contraindicated. (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid is for the induction of remission only. 318744 0

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover study design whereby each participant receives the test formulation of (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid, 1 x 12 mg capsule on one occasion and the innovator formulation of (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid, 2 x 10 mg capsules on one occasion with each dose separated by a two week washout period. The intervention for this trial is the test formulation of (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-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 before receiving a standardised high fat content meal and to fast for approximately 4 hours after each dose. The high fat content meal will consist of 2 eggs fried in butter, 2 slices of white toast, 120g hash brown patties, 2 slices of bacon and 240mL of whole milk comprising of approximately 800 to 1000 calories (approximately 50% of total caloric content of the meal derived from fat). This test meal will derive approximately 150, 250, and 500 600 calories from protein, carbohydrate, and fat, respectively.

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 12 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 & urine drugs of abuse 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 along with HIV, Hepatitis and drugs of abuse testing.

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] 324882 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)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid using one fully validated LC/MS/MS method. Validation will be conducted to comply with FDA guidelines.

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. The identification of each treatment will only be known to the Managing Director and Section Head - Trials and Regulatory Affairs or their delegate.
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).
