Brief summary

The objective of this study is to evaluate the bioequivalence of the test (new) formulation of 1 x 10 mg against the reference formulation (innovator brand of 1 x 10 mg tretinoin capsule) following oral administration of a single dose of 1 x 10 mg in healthy male subjects under fasting conditions.

Interventions

Single dose, crossover study design whereby each participant receives the test formulation of tretinoin (1 x 10 mg) on one occasion and the innovator formulation of tretinoin (1 x 10 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of tretinoin. Each dose (1 x 10 mg) 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. 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 before receiving each dose and 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 and for 11 hours after dosing. 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 healthy of participants along with HIV, Hepatitis and drugs of abuse testing.
