Outcome Measures

Primary Outcomes (1)

    Week 2 and Week 4

  • Number of Participants Reporting Who Had One or More Treatment-emergent Adverse Event (TEAE)

    On or after the start of study drug (Day 1) to 14 days after the last dose of study medication (up to 10 weeks)

  • Number of Participants With Markedly Abnormal Clinical Laboratory Findings

    From Day 1 to 14 days after the last dose of study medication (up to 10 weeks)

  • Number of Participants With Markedly Abnormal Electrocardiogram (ECG) Findings

    From Day 1 to 14 days after the last dose of study medication (up to 10 weeks)

  • Number of Participants With Markedly Abnormal Vital Sign Measurements
