Nature and Severity of Adverse Events (AEs) up to Day 21
On or after first drug administration up to end of study (Day 21).

An AE was defined as any untoward medical occurrence in a subject or clinical trial subject administered a medicinal product and which did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product. Serious Adverse Event (SAE) is an adverse event that at any dose: Results in death, Is life-threatening (i.e. the subject was at risk of death at the time of the event; it does not refer to an event which hypothetically might have caused death if it was more severe), Requires inpatient hospitalization or prolongation of existing hospitalization, Results in persistent or significant disability/incapacity, Is a congenital anomaly/birth defect, Is considered to be an important medical event.
