Summary

This trial is investigating whether a genetically-driven anti-hypertensive approach is better at controlling blood pressure and mitigating renal damage in Blacks who carry the risk allele for LSD1.

Who is the study for?

This trial is for Black individuals over 17 years old with high blood pressure, who may be on up to two blood pressure medications and have normal kidney function and lab tests. They must carry the rs587168 risk allele for LSD1. People with heart disease other than hypertension, diabetes, or a history of smoking are not eligible.

What is being tested?

The study is testing whether using Eplerenone (an MR antagonist) can better control blood pressure and prevent kidney damage in Blacks carrying the rs587168 allele compared to Amlodipine, based on their genetic makeup.

What are the potential side effects?

Eplerenone may cause increased potassium levels, dizziness or diarrhea; Amlodipine might lead to swelling, fatigue or palpitations. Side effects vary from person to person.

Experimental Treatment

Group I: Eplerenone ArmExperimental Treatment1 Intervention

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.
