Official title
An Open-Label, Randomized, Single Dose Three-Period Partial Crossover Study to Determine the Bioequivalence and Food Effect of a Combination Capsule Formulation of Dutasteride and Tamsulosin Hydrochloride (0.5mg/0.4mg) Compared to Concomitant Dosing of AVODART™ 0.5mg and Flomax 0.4mg Commercial Capsules in Healthy Male Subjects
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will be an open-label, randomized, single dose, three way partial crossover study in healthy male subjects. The aim of the study is to evaluate bioequivalence of a fixed dose combination (FDC) capsule of dutasteride and tamsulosin hydrochloride (HCl) (0.5 milligram \[mg\]/0.4 mg) relative to co-administration of dutasteride 0.5 mg capsules and tamsulosin hydrochloride 0.4 mg tablets in both the fed and fasted states. Approximately 98 healthy adult male subjects will be enrolled into the study. Subjects will receive single oral doses in 3 treatment periods and be randomized to one of twelve different treatment sequences (ABC, ACB, BAC, BCA, CAB, CBA, ABD, ADB, BAD, BDA, DAB, DBA) wherein A= commercially available tamsulosin hydrochloride 0.4 mg and dutasteride 0.5 mg in a fed state, B= fixed dose combination formulation of dutasteride and tamsulosin hydrochloride (0.5 mg dutasteride, 0.4 mg tamsulosin hydrochloride) in a fed state, C= commercially available tamsulosin hydrochloride 0.4 mg and dutasteride 0.5 mg in a fasted state, D= fixed dose combination formulation of dutasteride and tamsulosin hydrochloride (0.5 mg dutasteride, 0.4 mg tamsulosin hydrochloride) in a fasted state. Each treatment period will be separated by a minimum 28 day washout period. The total duration of a subject's involvement in this study is approximately 15-18 weeks.
