An AE is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. The term AE is used generally to include any AE whether serious or non-serious. A serious AE (SAE) is an AE that fulfills one or more of the following criteria: results in death, is immediately life-threatening; requires in-patient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability or incapacity or substantial disruption of the ability to conduct normal life functions; is a congenital abnormality or birth defect; is an important medical event that may jeopardize the participant or may require medical intervention to prevent one of the outcomes listed above.
