Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
