Summary

This study will be an open-label, randomized, single dose, three way crossover study in healthy male subjects. The aim of the study is to evaluate the pharmacokinetic parameters of two formulations of a fixed dose combination (FDC) capsule of dutasteride and tamsulosin hydrochloride (HCl) (0.5 milligram \[mg\]/0.2 mg) relative to co-administration of dutasteride 0.5 mg capsules and tamsulosin hydrochloride 0.2 mg tablets in both the fed and fasted states. Approximately 84 healthy adult male subjects will be enrolled into the study and split into two cohorts (fed and fasted), allowing for approximately 36 subjects to complete each cohort. Subjects from both cohorts will receive single oral doses in 3 treatment periods and be randomized to one of six different treatment sequences (ABC, ACB, BAC, BCA, CAB, CBA) wherein A= FDC1: Dutasteride and tamsulosin HCl (0.5 mg/0.2 mg), B= FDC2: Dutasteride and tamsulosin HCl (0.5 mg/0.2 mg), C= Co-administration of commercial formulations of dutasteride(0.5mg) and tamsulosin HCl (0.2mg). Each treatment period will be separated by a minimum 28 day washout period. Blood samples for pharmacokinetic analysis will be taken at regular intervals after dosing. Safety will be assessed by measurement of blood pressure, heart rate and review of adverse events.
