Outcomes
Primary Outcomes
Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE)
Time Frame: Day 1 to Week 24
An adverse event (AE) was defined as any untoward medical occurrence in a clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. TEAEs are defined as AEs with a start date and time on or after the first dose of study treatment through the end of study. Clinically significant changes in vital signs, physical exams, laboratory assessments and electrocardiograms were also reported as TEAEs.
Secondary Outcomes
- Change From Baseline in BK Viral Load(Baseline and Week 24)
