10.3. Appendix 3: Adverse Events: Definitions and Procedures for Recording,
Evaluating, Follow-up, and Reporting

10.3.1. Definition of AE

AE Definition

• An AE is any untoward medical occurrence in a patient or clinical study participant,
temporally associated with the use of study intervention, whether or not considered
related to the study intervention.

• NOTE: 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 study intervention.

Events Meeting the AE Definition

• Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis)
or other safety assessments (eg, ECG, radiological scans, vital sign measurements),
including those that worsen from baseline, considered clinically significant in the
medical and scientific judgment of the investigator Any abnormal laboratory test
results that meet any of the conditions below must be recorded as an AE:

• Is associated with accompanying symptoms.

• Requires additional diagnostic testing or medical/surgical intervention.

• Leads to a change in study dosing (outside of any protocol-specified dose
adjustments) or discontinuation from the study, significant additional
concomitant drug treatment, or other therapy.

• Exacerbation of a chronic or intermittent preexisting condition including either an
increase in frequency and/or intensity of the condition.

• New conditions detected or diagnosed after study intervention administration even
though it may have been present before the start of the study.

• Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

• Signs, symptoms, or the clinical sequelae of a suspected overdose of either study
intervention or a concomitant medication. Overdose per se will not be reported as
an AE/SAE unless it is an intentional overdose taken with possible
suicidal/self-harming intent. Such overdoses should be reported regardless of
sequelae.
