Primary Endpoints

Number of Participants With TEAEs, SAEs, and Severe TEAEs - Part 1: SAD
Day 1 to 37 days

An adverse event (AE) was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A serious adverse event (SAE) was defined as an AE: 1. resulting in death, 2. was life-threatening, 3. required inpatient hospitalization or prolongation of existing hospitalization, 4. resulted in persistent disability, 5. was a congenital anomaly/birth defect, or considered to be an important medical event. An adverse event was considered a Treatment-Emergent Adverse Event (TEAE) if the event started during the effective duration of treatment.
