Trial summary

Obesity and hypertension are independent risks for congestive heart failure (CHF) and chronic kidney disease. In obesity induced hypertension, the most common cause of human essential hypertension, the potential importance of mineralocorticoid receptor blockade has not been widely investigated.

About this study

Official title: Investigation of Reduction of Blood Pressure and Metabolic Rate in Obese Hypertensive Patients Using Eplerenone: Implications for Treatment of Hypertension and Heart Failure

Obesity and hypertension are independent risks for congestive heart failure (CHF) and chronic kidney disease. In obesity induced hypertension, the most common cause of human essential hypertension, the potential importance of mineralocorticoid receptor blockade has not been widely investigated. We propose to test the hypothesis that eplerenone reduces metabolic demand, improves cardiac function and attenuates glomerular hyperfiltration and microalbuminuria in obese patients. Our specific aims are to assess changes in basal metabolic rate, cardiac and renal function in obese hypertensive subjects treated with eplerenone compared to amlodipine.

Read the detailed description

The proposed trial will utilize an open label study design. Patients with hypertension and obesity will be recruited. After a 3-week washout period for patients currently on antihypertensive medication, eligible participants will be assigned to receive 25 mg of eplerenone or 5 mg of amlodipine. After a 4 week period on medication, drug will be advanced to 50 mg of eplerenone or 10 mg of amlodipine for an additional 4 weeks.

Protocol Synopsis:

  1. Recruit 20 study participants with a systolic blood pressure (SBP) between 140 and 160 mmHg and/or a diastolic blood pressure between 90 and 100 mmHg who also have a body mass index > 30-45. If participants are on antihypertensive treatment, they will undergo a 3-week washout period. The study participants will be identified in the Division of Hypertension.
  2. Assign study participants to receive 25 mg of eplerenone or 5 mg of amlodipine per day for 4 weeks. Up-titration to eplerenone 50 mg and amlodipine 10 mg for an additional 4 weeks.
  3. Obtain basal metabolic rate, cardiac output and other indices of cardiac performance, cognitive abilities, and rating of depression and anxiety symptoms at baseline and after 8 weeks of treatment.
  4. Obtain blood pressure measures at all visits.
  5. Obtain mood ratings at all visits.
  6. Compare basal metabolic rate, cardiac output and other indices of cardiac performance between treatment groups.
  7. Compare difference in SBP and DBP between treatment groups.
  8. Compare differences in plasma insulin, serum electrolytes, plasma renin activity, cortisol and aldosterone concentrations, urinary albumin excretion, and glomerular filtration rate between treatment groups.
  9. Compare mood rating as well as symptoms of depression and anxiety between treatment groups.

Questions about this trial

What is this clinical trial studying?

A study testing eplerenone, amlodipine, eplerenone and amlodipine in people with Obesity and Hypertension, run by University of Mississippi Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 29 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: funding to complete was inadequate). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Basal metabolic rate (time frame: Pre and post treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2018.
