What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of participants experiencing an Adverse Event (AE)
Time Frame: Up to 17 days
|
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.
An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
The number of participants who experienced an AE will be reported.
|
Up to 17 days
|
Number of participants discontinuing study treatment due to an AE
Time Frame: Up to 3 days
|
