An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant whether or not it is related to the investigational product. The investigator assesses the relationship of each event to the use of the investigational product. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first use of the investigational product.
