简要总结
A single-center, open-Label, randomized, single-dose, two-period, two-sequence, crossover study to assess the bioequivalence of test formulation entecavir tablets 1.0 mg with reference formulation entecavir tablets (Baraclude®) 1.0 mg in healthy adult subjects under fasting conditions.
详细描述
This is a single-center, open-label, randomized, single-dose, two-period, two-sequence, crossover study to assess the bioequivalence of test formulation Entecavir Tablets 1.0 mg with reference formulation Entecavir Tablets (Baraclude®) 1.0 mg in healthy adult subjects under fasting conditions. Each subject will be randomized to one of two treatment sequences (TR, RT) according to a randomization schedule prepared prior to the start of the study. There will be a 21-day washout between each single dose administration. Subjects in each group will be dosed on the same day for Day 1 of Period 1, and all subjects in each group will be crossed over to the alternate formulation and will be dosed on the same day for Day 22 of Period 2.
