Recent updates in hypertension classification by the American Heart Association (AHA) place nearly half of the U.S. population in the hypertensive category. Excess dietary salt is a major risk factor for hypertension, with 50% of hypertensive individuals exhibiting salt-sensitivity of blood pressure (SSBP). SSBP is an independent predictor of cardiovascular events and death. While kidney mechanisms in salt-sensing have been extensively studied, emerging evidence suggests that immune cells can also sense sodium (Na+).\n\nThis trial hypothesizes that myeloid cell-derived isolevuglandins (IsoLGs) drive endothelial dysfunction, perpetuating the salt-sensitive phenotype. Preliminary data indicate that targeting IsoLGs with the IsoLG scavenger 2-hydroxybenzylamine (2-HOBA) may interrupt this immune-vascular axis, reducing salt sensitivity and associated cardiovascular risks.\n\nThis phase 2 clinical trial aims to investigate the role of 2-HOBA in modulating immune cell function within blood vessels in hypertensive patients. The study will explore the impact of immunity on salt sensitivity and assess 2-HOBA's potential to reduce endothelial dysfunction, improve immune cell activation, and alleviate SSBP.",[25,26,27,28],"Salt Sensitivity of Blood Pressure","High Blood Pressure","Inflammation","Renin-Angiotensin-Aldosterone System",[30,31,32,33],"salt sensitivity","hypertension","renin-angiotensin-aldosterone system","immune cells","NOT_YET_RECRUITING","2026-05-20",{"date":37,"type":38},"2026-05-26","ACTUAL",{"date":40,"type":19},"2026-07",{"date":42,"type":19},"2031-07",{"name":44,"class":45},"Vanderbilt University Medical Center","OTHER",1,{"id":48,"slug":49,"hasResults":11,"nctId":50,"briefTitle":51,"officialTitle":52,"acronym":53,"eligibilityCriteria":54,"healthyVolunteers":55,"sex":15,"minAge":16,"maxAge":4,"enrollmentInfo":56,"targetDuration":4,"studyType":20,"phases":58,"briefSummary":60,"conditions":61,"keywords":67,"overallStatus":68,"whyStopped":4,"lastUpdateSubmitDate":69,"lastUpdatePostDateStruct":70,"startDateStruct":72,"completionDateStruct":74,"leadSponsor":76,"locationsCount":46},"100437088","phase-2-precision-bp-precision-chronopharamacotherapy-targeting-np-raas-bp-rhythm-axis-100437088","NCT04971720","PRECISION-BP: Precision Chronopharamacotherapy Targeting NP-RAAS-BP Rhythm Axis","Natriuretic Peptide-Renin-Angiotensin-Aldosterone System Rhythm Axis and Nocturnal Blood Pressure","PRECISION-BP","Inclusion Criteria:\n\n* Age more than or equal to 18 years of age\n* Body Mass Index between 30 to 45 kg\u002Fm\\^2\n* Blood pressure: Systolic BP more than or equal to 130mmHg and less than or equal to 160mmHg and diastolic blood pressure more than or equal to 80mmHg and less than or equal to 100mmHg.

These conditions are associated with an increased risk of cardiovascular (CV) events and death. Natriuretic Peptides (NPs) are hormones produced by the heart which directly regulate BP by causing dilation of blood vessels and by removing sodium and water from the body. NPs have a 24-hour day-night rhythm and this controls the day-night rhythm of BP as well. The NP-BP rhythm relationship is broken down in obese individuals. Obese individuals also have lower circulating NP levels. Lower circulating levels of NPs and elevated renin hormone (a part of the Renin-Angiotensin-Aldosterone System \\[RAAS\\]) at nighttime may contribute to the high nocturnal blood pressure in obese individuals which puts them at a higher risk of developing CV events. This current study seeks to determine the biological implications of chronopharmacology for synchronizing NP-RAAS-based blood pressure therapy with the physiological diurnal rhythms to restore the normal diurnal rhythm of blood pressure in obese individuals.",[62,63,64,65,66,28],"Obesity","Cardiovascular Diseases","Hypertension","Nocturnal Blood Pressure","Natriuretic Peptides",[66,65,28,62],"RECRUITING","2026-04-03",{"date":71,"type":38},"2026-04-09",{"date":73,"type":38},"2022-02-18",{"date":75,"type":19},"2027-01-01",{"name":77,"class":45},"University of Alabama at Birmingham","Renin Angiotensin Aldosterone System"]
