Comparative assessment in healthy male volunteers under fasting conditions of the absorption and pharmacokinetics of 1 generic formulation of (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid capsule against the innovator (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid capsule

A single dose, open label, balanced, randomized, 2 treatment, four period, two sequence, four-way, fully replicated crossover bioequivalence study of (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid capsules against the innovator (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid capsule conducted under fasting conditions in healthy male volunteers

Brief summary

The objective of this study is to evaluate the bioequivalence of the test (new) formulation of 25 mg (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid capsule relative to that of the reference formulation (innovator brand of 25 mg (2E,4E,6E,8E)-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethylnona-2,4,6,8-tetraenoic acid capsule ) following oral administration of a single dose of 25 mg in healthy male subjects under fasting conditions.

Interventions

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

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.
