Abnormal clinically significant vital signs included absolute systolic blood pressure (BP) values: less than (<) 90 millimeter of mercury (mmHg), maximum increase or decrease of greater than or equal to (>=) 30 mmHg from baseline; absolute diastolic BP value: <50 mmHg, maximum increase or decrease of >=20 mmHg from baseline; absolute heart rate values: >120 beats per minute (bpm).

Cohort 1 analysis set included all those participants in the safety analysis set (SAS) (all participants who receive at least one dose of study medication, including partial doses) who were randomized into cohort 1 of the study. Here, 'n' signifies those participants who were evaluable for particular category for each group respectively.

Abnormal clinically significant vital signs included absolute systolic BP values: <90 mmHg, maximum increase or decrease of >=30 mmHg from baseline; absolute diastolic BP values: <50 mmHg, maximum increase or decrease of >=20 mmHg from baseline; absolute heart rate values: >120 bpm.

Cohort 2 analysis set included all those participants in the SAS (all participants who receive at least one dose of study medication, including partial doses) who were randomized into cohort 2 of the study. Here, 'n' signifies those participants who were evaluable for particular category for each group respectively.

Abnormal ECG findings included maximum value of >=300 millisecond (msec), maximum increase of >=25% for baseline value of >200 msec and maximum increase of >=50% for baseline value of <=200 msec for PR interval (int); maximum value of >=200 msec, maximum increase of >=25% for baseline value of >100 msec and maximum increase of >=50% for baseline value of <=100 msec for QRS interval; maximum value of >=500 msec for QT interval; maximum value of 450 to <480, 480 to <500 and >=500 msec, increase of >=30 to <60 and >=60 msec for QT interval corrected using Fridericia's formula (QTcF interval).

For hematology, liver function, renal function, electrolytes, clinical chemistry, abnormality was reported if the observed value was more than or less than X times the upper limit of normal (ULN) or lower limit of normal (LLN) respectively; X=specified in categories of each parameter in the measured values section. For urinalysis of glucose, ketones, protein, blood, abnormality was reported if result was >=1 in qualitative test of respective parameters, indicating levels in urine were abnormal. Urine pH and specific gravity abnormality reported if pH >8 and specific gravity <1.003 or >1.030.

Cohort 1 analysis set. Here, 'N' (number of participants analyzed) signifies those participants who were evaluable for this measure for each group respectively. Here, 'n' signifies those participants who were evaluable for particular category for each group respectively.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
