About this study

The purpose of this research study is to determine whether blood pressure treatment regimens with spironolactone are better than blood pressure treatment regimens without spironolactone at lowering blood pressure in stroke survivors.

Read the detailed description

This is a pragmatic, randomized, open-label, blinded-endpoint trial comparing spironolactone-containing antihypertensive regimens versus standard antihypertensive regimens based on the 2017 AHA/ACC guidelines in stroke survivors.

This study will randomize a total of 200 patients, 100 white and 100 non-white patients, at least three weeks after last known normal or symptom discovery/onset of their stroke to an antihypertensive regimen with spironolactone once daily or standard BP control based on the 2017 AHA/ACC guidelines for 1 year.

Participants will undergo baseline testing for neurohormonal levels and will be followed for 12 months with regular assessment of home BP readings. The primary outcome of home systolic BP will be measured at 3 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Average change in home systolic blood pressure at 3 months

    The average home systolic blood pressure will be measured using a home blood pressure cuff

    Measured: Baseline, 3 month

Secondary outcomes (5)
  1. Proportion of patients achieving BP < 130/80 mm Hg

    The proportion of patients achieving BP < 130/80 mm Hg at 3 months will be measured

    Measured: 3 months

  2. Number of antihypertensive medications at 3 months

    The number of antihypertensive medications at 3 months will be collected

    Measured: 3 months

  3. Number of antihypertensive medications at 1 year

    The number of antihypertensive medications at 1 year will be collected

    Measured: 1 year

  4. Stroke, myocardial infarction, or death

    Incidence of stroke of any type (ischemic or hemorrhagic), myocardial infarction, or death from any cause

    Measured: 1 year

  5. Change in modified Rankin Scale score

    Measure of neurologic disability (0=no disability to 6=dead)

    Measured: Baseline, 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Spironolactone Pill in people with Intracerebral Hemorrhage and Ischemic Stroke, run by Yale University at 5 sites 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 4 inclusion and 12 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: under way, not looking for participants, as of the sponsor's last update on 4 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Average change in home systolic blood pressure at 3 months (time frame: Baseline, 3 month). 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 4 Sep 2026.
