Study Endpoints
Primary Endpoints
Change From Baseline to Day 10 in 24-hour Mean Ambulatory Systolic Blood Pressure (SBP)
Baseline and Day 10

SBP was measured using ambulatory blood pressure monitoring (ABPM) on Day -1 and Day 10 of each treatment period. The 24-hour least squares (LS) mean ambulatory SBP change from baseline was then determined for Day 10, the last day of multiple dose treatment. Baseline is defined as the average 24-hour SBP for each participant on Day -1. Increased values represent an increase in hypertensive severity.

Number of Participants Who Experienced at Least One Adverse Event (AE)
Up to 70 days

An AE is defined as any unfavorable and unintended medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

Number of Participants Who Discontinued the Study Medication Due to an AE
Up to 70 days

An AE is defined as any unfavorable and unintended medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

Secondary Endpoints
Change From Baseline to Day 10 in 24-hour Mean Ambulatory Diastolic Blood Pressure (DBP)
Baseline and Day 10
Change From Baseline to Day 10 in Maximum Moving Average (maxMAΔ) Blood Pressure Measured Over 4 Hours
Up to 4 hours postdose on Days 1 and 10
Area Under the Plasma Concentration-time Curve From Time 0 to 12 Hours (AUC0-12hr) of MK-8457
