Summary

This study will be an open-label, randomized, single dose, two-period crossover study to determine the bioavailability of a fixed dose combination capsule formulation of dutasteride and tamsulosin hydrochloride (0.5mg/0.2mg) relative to co-administration of dutasteride 0.5mg capsules and tamsulosin hydrochloride 0.2mg tablets in healthy male subjects of North East Asian and non-Asian ancestry. Subjects will receive single oral doses of a combination capsule formulation of dutasteride 0.5 mg/ tamsulosin 0.2 mg in a fed or fasted state or concomitant dosing of dutasteride 0.5 mg and the Japan-sourced Harnal-D 0.2 mg in a fed or fasted state. Each dose of study medication will be separated by a 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, safety laboratory data, and review of adverse events. The study will enrol 88 healthy male subjects to ensure that 80 complete the study. At least twenty percent of the study population will be of Japanese ancestry, approximately 20% will be of Chinese ancestry and approximately 20% of Korean ancestry while the remainder of the population will be of non-Asian ancestry.

Interventions

DRUG

Dutasteride (0.5mg); Tamsulosin hydrochloride (0.2mg); fixed dose combination product of duatsteride (0.5mg) and tamsulosin hydrochloride (0.2mg)

In the first dosing session, twenty-two subjects of each cohort will receive the FDC capsule (dutasteride and tamsulosin hydrochloride (0.5mg/0.2mg) and the other 22 will receive commercial capsules of dutasteride 0.5mg and commercial tablets of tamsulosin hydrochloride 0.2mg co-administered. Following a wash-out period of at least 28 days, those subjects who received the FDC capsule in session 1, will be co-administered commercial capsules of dutasteride 0.5mg and commercial tablets of tamsulosin hydrochloride 0.2mg while those who were co-administered commercial capsules of dutasteride 0.5mg and commercial tablets of tamsulosin hydrochloride 0.2mg in session 1 will receive the FDC capsule in the second dosing session.
