the Day 8, Day 15 and the final follow-up visit on Day 22through the duration of the
study
4. Have a creatinine clearance (CLCr) = 80 mL/min;

Summary
Brief summary
This is a phase 1, randomized, parallel-group, single-center study in healthy adult subjects.
The study will be conducted in two parts sequentially:
Part 1 is an open-label, two-arm, active-controlled design to evaluate the PK and safety of
single oral dose of ETV XR tablet (1.5 mg) in healthy subjects. Part 1 will consist of 16
healthy subjects.
Part 2 is a double-blind, three-arm, placebo-controlled design to evaluate the PK and safety
of higher oral doses of ETV XR tablet (3 mg and 6 mg) in healthy subjects. Part 2 will
consist of 24 healthy subjects.
