A SAE is defined as any untoward medical occurrence that, at any dose: results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant; abnormal pregnancy outcomes; or any other situation according to medical or scientific judgment. The intensity of SAEs is assessed as per the Division of Acquired Immunodeficiency Syndrome (DAIDS) criteria Version 2.1 where grades are defined based on numeric criteria as follows Grade 1: mild; Grade 2: moderate; Grade 3: severe; Grade 4: potentially life-threatening; Grade 5: death. A higher grade indicates greater severity. Any = occurrence of the event regardless of intensity grade and treatment relationship. Treatment related = occurrence of the event which, in the investigator's opinion, is related to the administered treatment regardless of the intensity grade.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. The intensity of non-serious AEs is assessed using the DAIDS criteria Version 2.1 where grades are defined based on numeric criteria as follows Grade 1: mild; Grade 2: moderate; Grade 3: severe; Grade 4: potentially life-threatening; Grade 5: death. A higher grade indicates greater severity. Any = occurrence of the event regardless of intensity grade and treatment relationship. Treatment related = occurrence of the event which, in the investigator's opinion, is related to the administered treatment regardless of the intensity grade.
