A serious adverse event (SAE) was defined as any untoward medical occurrence that at any dose: Results in death, Is life-threatening, Requires in patient hospitalization or prolongation of existing hospitalization,Is a congenital anomaly or birth defect, Is an infection that requires treatment parenteral antibiotics, Other important medical events which based on medical or scientific judgement may jeopardize the patients, or may require medical or surgical intervention to prevent any of the above. |

Outcome results
Area Under the Curve From 0 to the Time of the Last Quantifiable Concentration (AUC(0-t)) for a Single Dose of Brivaracetam
AUC(0-t) is the area under the curve from time 0 to the time of the last quantifiable concentration.
Time frame: Blood samples for this analysis were collected on Predose (Day 1), 0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36, and 48 hours postdose
Population: Pharmacokinetic Per Protocol Set (PK-PPS) included all randomized study participants who were included in the SS, had no important protocol deviations (IPDs) that were considered to impact the data validity for analysis of the primary study objective, and had a sufficient number of bioanalytical assessments to calculate reliable estimates for the primary pharmacokinetic parameters for both treatments.
