Study Endpoints

Primary Endpoints

Number of Participants Who Experience One or More Adverse Events (AEs)
Up to approximately 169 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 is presented.

Number of Participants Who Discontinue Study Intervention Due to an AE
Up to approximately 85 days
