About this study
Official title: Role of LSD1 in Hypertension in Blacks
Lysine specific demethylase-1 (LSD1) is an epigenetic regulator of gene transcription involved in the pathophysiology of elevated blood pressure and likely renal damage in Blacks. This project investigates whether a genetically driven anti-hypertensive approach proves superior in controlling blood pressure and mitigating renal injury in Blacks who carry the risk allele for LSD1 (rs587168). The findings of these investigations may lead to a new approach in treating a subset (~30%) of the essential hypertension population (Black LSD1 risk allele hypertensives).
Read the detailed description
This proof-of-principle physiologic study in hypertensive Black LSD1 risk allele carriers testing the hypothesis that reductions in blood pressure will be greater with a genetically-driven anti-hypertensive approach (mineralocorticoid receptor antagonist, eplerenone) compared to a non-specific approach (amlodipine). 56 participants will be enrolled in a 12-week randomized, double-blind, active controlled, outpatient study to assess whether eplerenone (LSD1 specific treatment) proves superior in 24-hr ambulatory systolic blood pressure reduction than amlodipine (non-specific treatment). Participants will be randomized to either eplerenone 50mg or amlodipine 2.5mg with escalations in dose of study drug every 4 weeks if the participant's blood pressure is > 140/90.

| Study group | Role | What they receive |
|---|---|---|
| Eplerenone Arm | Experimental | We posit that individuals who carry the LSD1 risk allele have increased mineralocorticoid receptor activity, which results in hypertension. Thus, our mechanistic clinical study will assess whether hypertensive LSD1 risk allele carriers will show significantly greater reductions in blood pressure with a specific aldosterone mediated treatment approach (mineralocorticoid receptor blockade) than with a non-specific approach (amlodipine). To test this hypothesis, we will perform a randomized, double-blind, active controlled study in hypertensive carriers of the LSD1 risk allele using a novel two-limb, proof-of-principle study. Our primary outcome will be a liberal salt diet systolic blood pressure. Therefore, this mechanistic trial will provide support for using a genetic marker that identifies individuals who are uniquely responsive to mineralocorticoid receptor blockade--personalized, precision medicine.

What is being measured
The primary outcome is the main question the study is designed to answer.
24-hour systolic ambulatory blood pressure
Subjects will be counseled regarding liberal salt dietary intake to ensure similar intakes in all subjects [Na+ (200 mEq), potassium (K+, 100 mEq) and calcium (800 mg)]. After completion of this diet for 6 days, the subject will collect a 24-hour ambulatory blood pressure. Procedure will be performed before randomization and after 4 weeks of therapy.
Measured: Change in systolic blood pressure between baseline and 4 weeks on study drug

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Eplerenone and Amlodipine in people with Hypertension and Mineralocorticoid Excess, 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 6 inclusion and 7 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 1 Oct 2026. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
24-hour systolic ambulatory blood pressure (time frame: Change in systolic blood pressure between baseline and 4 weeks on study drug). 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 1 Oct 2026.
