- Primary Outcome Measures
Name Time Method Percentage of Participants Who Were Hospitalized and/or Died Through Day 29 (Primary Pre-specified Analysis) Up to 29 days The percentage of participants who were hospitalized and/or died through Day 29 is presented.

Number of Participants With an Adverse Event (AE) Up to 318 days The number of participants with at least 1 AE is presented. An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
