Outcome results

Primary

Change From Baseline to Week 8 in Trough, Cuff, Seated Diastolic Blood Pressure (SDBP)

The change from baseline in trough SDBP at Week 8 as measured by the Omron monitor. Morning doses of study medication were taken after the exam on study visit days, therefore exam measurements were taken when medication levels were at its lowest ('the trough'). Following a 5-minute rest period, three separate blood pressure measurements were taken with a full 2-minute (not exceeding 5 minutes) interval between measurements, with the cuff fully deflated between measurements. The mean of the 3 seated blood pressure measurements constitute the blood pressure value for the visit.

Time frame: Day 0, Week 8

Population: The Efficacy Population included participants who received at least 1 dose of double-blind randomized study medication and had a baseline and at least 1 post-baseline blood pressure measurement. Last observation carried forward.

Change From Baseline in Mean Ambulatory Blood Pressure During the Final 2, 4, and 6 Hours of the Dosing Interval at Week 8

In week 8, participants arrived at the site in the morning without having taken that day's dose of medication. Once the ambulatory blood pressure monitor (ABPM) had been applied, medication was taken and the participant wore the ABPM for a period of 24-hours. Systolic and diastolic blood pressure readings taken in the final 2, 4, and 6 hours of the 24-hour ABPM cycle are summarized.

Time frame: Baseline, Week 8

Population: The ambulatory blood pressure monitor (ABPM) population was defined as participants in the efficacy population that had valid baseline and Week 8 ABPM data. Valid (technically successful) ABPM had at least 23 hours of ABPM data.

Change From Baseline to Week 2 in Trough, Cuff, Seated Blood Pressure

The change from baseline in trough systolic and diastolic blood pressure at Week 2 as measured by the Omron monitor. Morning doses of study medication were taken after the exam, therefore exam measurements were taken when medication levels were at its lowest ('the trough'). Following a 5-minute rest period, three separate blood pressure measurements were taken with a full 2-minute (not exceeding 5 minutes) interval between measurements, with the cuff fully deflated between measurements. The mean of the 3 seated blood pressure measurements constitute the blood pressure value for the visit.

Time frame: Baseline, Week 2

Population: The efficacy population was defined as participants who received at least 1 dose of double-blind randomized study medication and had a baseline and at least 1 post-baseline blood pressure measurement. Last observation carried forward.

Percentage of Participants Achieving Blood Pressure Goals at Week 8

Percentage of participants who achieved the following goals: Systolic blood pressure: \<140 mmHg, \<135 mmHg, \<130 mmHg, \<120 mmHg Diastolic blood pressure: \<90 mmHg, \<85 mmHg, \<80 mmHg Blood pressure: \<140/90 mmHg, \<135/80 mmHg, \<130/80 mmHg, \<120/80 mmHg

Time frame: Week 8

Population: Efficacy population. Last observation carried forward. Denominator is the number of participants who have seated cuff BP measurement in each treatment group at any visit during the entire randomized treatment phase. Participants randomized to placebo-olmesartan, the measurement is after at least one dose of olmesartan.
