An adverse events (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect; other important medical events that may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed before

Urine samples were collected at indicated time points for the assessment of Urinary pH. Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0). Baseline was defined as Day -1 for Period 1.

Population: Safety Population. Only those participants with data available at the specified time points were analyzed (represented by n= X in the category titles).

Twelve-lead ECGs was performed with the participant in a supine or semi-supine position after a rest of at least 10 minutes using an automated ECG machine to measure PR interval, QRS duration, QT Interval, QTcF Interval and QTcB interval. Baseline was defined as Day 1 (Pre-dose) for each Period.
