TEAEs included both serious and non-serious AEs.

Number of Participants With Clinically Significant Abnormalities in Vital Signs Baseline up to Day 57 Vital signs included measurement of pulse rate, systolic and diastolic blood pressure, respiratory rate, and body temperature. Clinically significant vital signs abnormalities assessment was based on Investigator interpretation. Number of participants with clinically significant abnormalities in vital signs were reported.
Number of Participants With Clinically Significant Abnormalities in Physical Examination Baseline up to Day 57 Physical examination included weight and height measurements. Clinically significant physical examination abnormalities assessment was based on Investigator interpretation. Number of participants with clinically significant abnormalities in physical examination were reported.
