Titles & IDs
Public title
A randomised, open label study to compare the bioavailability of 12mg (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid capsules against the innovator 10mg (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid capsules conducted under fasting condition in healthy male volunteers.
Scientific title
A single dose, randomized, open label, pilot study of a test formulation of (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid capsule in a 2 way crossover comparison against the innovator (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid capsule conducted under fasting conditions in healthy male volunteers.

Health condition
Health condition(s) or problem(s) studied:
Tretinoin 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. Tretinoin is for the induction of remission only. 316465 0

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover study design whereby each participant receives the test formulation of 1 x 12 mg (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid capsule on one occasion and the innovator formulation of 1 x 10 mg (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid capsule on one occasion with each dose separated by a two week washout period. The intervention for this trial is the test capsule formulation.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for water consumed with the dose).
Participants are required not to eat for 10 hours before receiving each dose and to fast for approximately 4 hours after receiving each dose.

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 along with HIV, Hepatitis and drugs of abuse testing.

Each dose (1 x 12 mg (test) or 10 mg (Reference)) 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, crossover study whereby each participant receives the test formulation (1 x 12 mg) on one occasion and the innovator formulation (1 x 10 mg) on one occasion with each dose separated by a two week washout period. The comparator/control for this trial is the innovator capsule formulation.

Outcomes
Primary outcome [1] 323057 0
To compare the bioavailability of (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid (as summarised by Cmax and AUC) for the 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 a fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.

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 - Trails and Regulatory Affairs.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each participant will be given 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. Sequence generation will be by using a simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
