Subjects will be released from confinement on Day 20 after the completion of all study procedures including the 120-hour blood sample collection. Thereafter, subjects will return for outpatient visits on Days 25 and 30 as well as 30 days after the last dose of study drug. A ± 2 day window will be permitted on the 30-day Follow-up Visit to accommodate subject scheduling.
