Age within ±10 years to his/her matched participant(s) enrolled in the study. 25. Normal BP measured on the same arm, after 5 min in the supine position at Screening and Baseline defined as: * SBP 90-140 mmHg, DBP 60-90 mmHg, and pulse rate 60-100 bpm (inclusive) for subjects \< 65 years of age. * SBP 95-160 mmHg, DBP 65-95 mmHg, and pulse rate 60-100 bpm (inclusive) for subjects ≥ 65 years of age. Exclusion Criteria: Participants with normal renal function and participants with mild, moderate, or severe renal impairment who meet one or more of the following criteria will not be considered eligible to participate in the clinical study: 1.

History or presence of a clinically relevant abnormality in any organ system, that is incapacitating, requires hospitalization, or in the opinion of the investigator makes the participant ineligible for enrollment in the study. 24.
