A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acidic pH (5.0 - 6.0). Baseline was defined as the latest pre-dose assessment with a non-missing value for each period, including those from unscheduled visits. | Baseline (Day -1) and Day 4 | 
| Number of Participants With Abnormal Values on Urinalysis by Dipstick | Urine samples were collected at indicated time points to analyze parameters including glucose, protein, blood, and ketones by dipstick. The dipstick test gives results in a semi-quantitative manner and results for urinalysis parameters can be read as Negative, Trace, 1+ (low concentrations present), 2+ (moderate concentrations present), 3+ (high concentrations present) and 4+ (very high concentrations present) indicating proportional concentrations in the urine sample. | Baseline (Day -1) and Day 4 | 
| Change From Baseline in Electrocardiogram (ECG) Parameters: PR Interval, QRS Duration, QT Interval and Corrected QT Interval According to Fridericia's Formula (QTcF) | Single 12-lead ECGs were obtained to measure PR Interval, QRS Duration, QT Interval and QTcF Interval. Baseline was defined as the latest pre-dose assessment with a non-missing value for each period, including those from unscheduled visits. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value. | Baseline (Day -1) and Day 4 | 
| Absolute Values of ECG Parameters: PR Interval, QRS Duration, QT Interval and QTcF | Single 12-lead ECGs were obtained to measure PR Interval, QRS Duration, QT Interval and QTcF Interval. Baseline was defined as the latest pre-dose assessment with a non-missing value for each period, including those from unscheduled visits. | Baseline (Day -1) and Day 4 | 
| Change From Baseline in Vital Signs Measurements: Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) | SBP and DBP were measured in the supine or semi-supine position with a completely automated device after at least 5 minutes of rest for the participant in a quiet setting without distractions. Baseline was defined as the latest pre-dose assessment with a non-missing value for each period, including those from unscheduled visits. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value. | Baseline (Day -1) and Day 4 | 
| Absolute Values of Vital Signs Measurements: SBP and DBP | SBP and DBP were measured in the supine or semi-supine position with a completely automated device after at least 5 minutes of rest for the participant in a quiet setting without distractions. Baseline was defined as the latest pre-dose assessment with a non-missing value for each period, including those from unscheduled visits. | Baseline (Day -1) and Day 4 | 
| Change From Baseline in Vital Signs Measurements: Pulse Rate | Pulse rate were measured in the supine or semi-supine position with a completely automated device after at least 5 minutes of rest for the participant in a quiet setting without distractions. Baseline was defined as the latest pre-dose assessment with a non-missing value for each period, including those from unscheduled visits. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value. | Baseline (Day -1) and Day 4 | 
| Absolute Values of Vital Signs Measurements: Pulse Rate | Pulse rate were measured in the supine or semi-supine position with a completely automated device after at least 5 minutes of rest for the participant in a quiet setting without distractions. Baseline was defined as the latest pre-dose assessment with a non-missing value for each period, including those from unscheduled visits. | Baseline (Day -1) and Day 4 |
