Descriptive Information
Brief Title  ICMJE Bioequivalence Study of Dutasteride Capsules in Healthy Japanese Male Subjects
Official Title  ICMJE Bioequivalence Study of Dutasteride Capsules-An Evaluation of the Bioequivalence of Dutasteride Capsule Manufactured at GSK Compared to Dutasteride Capsule Manufactured at Catalent in Healthy Japanese Male Subjects
Brief Summary This will be a single center, open-label, single dose, randomized and 2-way crossover study in healthy Japanese male subjects under fasting conditions. The study will be conducted to determine the bioequivalence between dutasteride capsules manufactured at GSK (test product) and dutasteride capsule manufactured at Catalent (reference product) in healthy Japanese male subjects. Subjects will have a screening visit within 30 days prior to the first dose of study treatment, two treatment periods separated by 28-days washout period, a re-visit 10-14 days after the second dose for the first follow-up and a second follow up via telephone 50-54 days after the second dose. The total duration of the study will be approximately 15 weeks from screening to the second follow up.
