Number of Participants Reporting Treatment-Emergent Adverse Events (TEAEs)
Day 1-11 in each period, along with the 29-36 day post final dose follow-up

An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An adverse event is considered a TEAE if the event started during the effective duration of treatment. All events that started on or after the first dosing day and time/start time, if collected, but before the end of the study were flagged as TEAEs. The algorithm did not consider any events that started prior to the first dose date. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

Number of Participants With Clinical Laboratory Abnormalities Meeting Pre-Defined Categorical Criteria Without Regard to Baseline Abnormality
Day 1-11 in each period, along with the 29-36 day post final dose follow-up

Pre-defined categorical criteria for laboratory abnormalities included: Lymphocytes \<0.8 x lower limit of normal (LLN); Basophils/Leukocytes \> 1.2 x upper limit of normal (ULN); Eosinophils/Leukocytes \>1.2 x ULN; Monocytes/Leukocytes \>1.2 x ULN; low-density lipoprotein (LDL) Direct Endpoint Measure \>1.2 x ULN; Triglycerides \>1.3 x ULN; Specific Gravity \<1.003 or \>1.030; pH \>8; Ketones ≥1; Urobilinogen (EU) ≥1; URINE Bilirubin ≥1; Leukocyte Esterase ≥1.

Number of Participants With Vital Signs Abnormalities Meeting Pre-Defined Categorical Criteria
Day 1-11 in each period, along with the 29-36 day post final dose follow-up

Vital signs categorical criteria: 1) supine systolic blood pressure (SBP) \<90 millimeters of mercury (mmHg); 2) supine diastolic blood pressure (DBP) \<50 mmHg; 3) supine pulse rate \<40 or \>120 beats per minute (bpm); 4) change from baseline (increase or decrease) in supine SBP greater than or equal to (≥) 30 mmHg; 5) change from baseline (increase or decrease) in supine DBP ≥ 20 mmHg.

Number of Participants With Abnormal Electrocardiogram (ECG) Meeting Pre-Defined Categorical Criteria
Day 1-11 in each period, along with the 29-36 day post final dose follow-up

ECG categorical criteria: 1. PR interval (the interval between the start of the P wave and the start of the QRS complex, corresponding to the time between the onset of the atrial depolarization and onset of ventricular depolarization): a) ≥300 millisecond (msec), b) ≥25% increase when baseline is \> 200 msec, c) ≥50% increase when baseline is less than or equal to (≤) 200 msec. 2\. QRS interval (time from ECG Q wave to the end of the S wave corresponding to ventricle depolarization): a) ≥140 msec, b) ≥50% increase from baseline. 3\. QTcF interval (QT corrected using the Fridericia formula): a) \>450 msec and ≤480 msec, b) \>480 msec and ≤500 msec, c) \>500 msec, d) \>30 msec and ≤60 msec increase from baseline, e) \>60 msec increase from baseline.
