An adverse event (AE) is defined as any untoward medical occurrence in a participant who is administered a pharmaceutical product and which does not necessarily have a causal relationship with the treatment. Serious adverse events (SAEs) are 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, other situations judged by physician, is associated with liver injury and impaired liver function. Adverse events of medical interest (AEMIs) are AEs of scientific interest specific to the drug class. Treatment-emergent events (i.e., TEAEs, TESAEs and TEAEMIs) were defined as events that commence on or after the time of first study drug administration.
