Who may be able to join

  • Participants must be healthy, with no prior history of hypertension, no family history of hypertension, diabetes, stroke or cardiac disease in first-degree relatives before the age of 70 years and have an average (two measurements) blood pressure of <130/89 mm Hg and >100/50 mmHg at the screening visit.

About this study

The purpose of this research protocol is to determine if the same effects are observed in vivo in humans using a similar approach. Demonstrating that mineralocorticoid acts on zona glomerulosa cells to regulate aldosterone production in a short feedback loop would provide important insight into hormone regulation, and explain variability in pathophysiologic states such as hypertension and cardiovascular diseases.

Read the detailed description

In order to provide additional evidence indicating the presence of functional and in order to provide additional evidence indicating the presence of functional mineralocorticoid receptors (MR) on zona glomerulosa (ZG) cells, the investigators propose the following protocol in healthy volunteers. The investigators will evaluate aldosterone and cortisol production in response to an angiotensin II infusion after three separate test conditions: 1) placebo, 2) following a single dose of fludrocortisone, and 3) following a single dose of eplerenone (a MR antagonist).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Fludrocortisone and Eplerenone in people with Healthy Volunteers, run by Brigham and Women's Hospital 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 3 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: finished, as of the sponsor's last update on 8 Jun 2021. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Serum aldosterone after angiotensin II infusion (time frame: 5 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02871648, which also lists 2 linked publications.

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 8 Jun 2021.
