Overview
Brief Summary
The purpose of this study is to determine the safety and efficacy of azilsartan medoxomil, once daily (QD), compared to placebo and olmesartan in participants with essential hypertension.
Detailed Description
Hypertension affects approximately 50 million individuals in the United States. As the population ages, the prevalence of hypertension will continue to increase if broad and effective preventive measures are not implemented. According to the World Health Organization, hypertension is the most common attributable cause of preventable death in developed nations, as uncontrolled hypertension greatly increases the risk of cardiovascular disease, cerebrovascular disease, and renal failure. Despite the availability of antihypertensive treatments, hypertension remains inadequately controlled; only about one-third of patients continue to maintain control successfully. TAK-491 (azilsartan medoxomil) is an angiotensin II receptor blocker and this study is being conducted to evaluate the efficacy and safety of oral azilsartan medoxomil compared to placebo and olmesartan in subjects with essential hypertension. Individuals who want to participate in this study will be required to provide written informed consent. Study participation is anticipated to be about 11 weeks. Multiple procedures will occur at each visit which may include fasting, blood collection, urine collection, vital signs including sitting blood pressure and pulse, body height and weight, physical examinations and electrocardiograms. Outside of the study center, participants will be required to wear an ambulatory blood pressure monitoring device at 24 hour intervals.

Outcomes
Primary Outcomes
Change From Baseline in the 24-hour Mean Systolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring.
Time Frame: Baseline and Week 6.
The change in 24-hour mean systolic blood pressure measured at week 6 relative to baseline. Ambulatory blood pressure monitoring measures blood pressure at regular intervals throughout the day and night. The 24-hour mean is the average of all measurements recorded for 24 hours after dosing.
Secondary Outcomes
- Change From Baseline in Mean Trough Clinic Sitting Systolic Blood Pressure(Baseline and Week 6.)
- Change From Baseline in the 24-hour Mean Diastolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring.(Baseline and Week 6.)
- Change From Baseline in Mean Trough Clinic Sitting Diastolic Blood Pressure(Baseline and Week 6.)
- Change From Baseline in Daytime (6am to 10 pm) Mean Systolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring.(Baseline and Week 6.)
- Change From Baseline in Daytime (6am to 10 pm) Mean Diastolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring.(Baseline and Week 6.)
- Change From Baseline in the Nighttime (12 am to 6 am) Mean Systolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring.(Baseline and Week 6.)
- Change From Baseline in the Nighttime (12 am to 6 am) Mean Diastolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring.(Baseline and Week 6.)
- Change From Baseline in the 12-hour Mean Systolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring(Baseline and Week 6.)
- Change From Baseline in the 12-hour Mean Diastolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring(Baseline and Week 6.)
- Change From Baseline in the Trough (22-24-hr) Mean Systolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring.(Baseline and Week 6.)
- Change From Baseline in the Trough (22-24-hr) Mean Diastolic Blood Pressure Measured by Ambulatory Blood Pressure Monitoring.(Baseline and Week 6.)
- Percentage of Participants Who Achieve a Clinic Systolic Blood Pressure Response, Defined as < 140 mm Hg and/or Reduction From Baseline ≥ 20 mm Hg(Baseline and Week 6.)
- Percentage of Participants Who Achieve a Clinic Diastolic Blood Pressure Response, Defined as < 90 mm Hg and/or Reduction From Baseline ≥ 10 mm Hg(Baseline and Week 6.)
- Percentage of Participants Who Achieve Both a Clinic Diastolic and Systolic Blood Pressure Response(Baseline and Week 6.)
