An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is 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, may jeopardize the participant or require medical or surgical intervention to prevent one of the other outcomes listed in the definition above, or is an event of possible drug-induced liver injury.

Safety Population consisted of all participants enrolled in the study and who had received at least one dose of study drug.

Baseline was considered to be Day 1 pre-breakfast. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline is set to missing as well. If measurements were taken in triplicate, then the mean of the triplicate measurements was used as the Baseline.

AUC with respect to that time interval was calculated using the linear trapezoidal rule. The weighted mean was determined by dividing the AUC by the observed length of the collection interval (time of last assessment - time of first assessment in hours). In order for the AUC to be calculated, the first and last time points and at least one additional assessment falling between the two must be non-missing.
