Early Mineralocorticoid Receptor Antagonist Therapy for Low-Renin Essential Hypertension (EMERALD)

2026年11月6日 更新者：China National Center for Cardiovascular Diseases

Early Mineralocorticoid Receptor Antagonist Therapy for Low-Renin Essential Hypertension: A Randomized Controlled Study

This study aims to evaluate the efficacy and safety of early initiation of eplerenone, a second-generation mineralocorticoid receptor antagonist, compared with standard antihypertensive treatment in adults with low-renin essential hypertension. The study will assess whether an eplerenone-based treatment strategy provides greater blood pressure reduction, improves blood pressure control, and reduces antihypertensive medication burden compared with standard treatment.

详细说明

The EMERALD Trial is a prospective, randomized, open-label, controlled study designed to compare the efficacy and safety of early initiation of a second-generation mineralocorticoid receptor antagonist with standard antihypertensive treatment in adults with low-renin essential hypertension.

A total of 128 eligible participants will be enrolled and randomly assigned in a 1:1 ratio to either an intervention group or a control group.

In the intervention group, participants will receive an eplerenone-based treatment strategy, starting with eplerenone 50 mg once daily. The dose may be gradually increased to 50 mg twice daily, and additional antihypertensive medications may be added according to blood pressure response and treatment tolerability.

In the control group, participants will receive standard antihypertensive treatment based on current clinical guidelines and routine practice. Medication doses may be gradually increased or treatment regimens adjusted according to blood pressure response and treatment tolerability.

In both groups, treatment will be adjusted to achieve an office seated blood pressure below 140/90 mmHg.

Participants will be followed for 24 weeks, with scheduled clinic visits at baseline and weeks 4, 12, and 24, supplemented by remote follow-up between visits.

The primary outcome is the change in mean daytime systolic blood pressure from baseline to week 12, assessed by 24-hour ambulatory blood pressure monitoring. Secondary outcomes include changes in office and ambulatory blood pressure, blood pressure control rates, treatment adjustments, time to blood pressure control, and antihypertensive medication burden assessed using defined daily doses.

Exploratory outcomes include changes in cardiac structure and function, urinary albumin-to-creatinine ratio, and circulating renin and aldosterone levels. Treatment safety will be evaluated throughout the study, with particular attention to hyperkalemia, changes in kidney function, symptomatic hypotension, and other adverse events.

参与者组/臂
干预/治疗
实验性的：Early Eplerenone-Based Treatment

Participants will receive stepped antihypertensive treatment starting with eplerenone 50 mg orally once daily. Treatment will be intensified as needed by sequentially adding amlodipine 5 mg once daily, increasing eplerenone to 50 mg twice daily, increasing amlodipine to 5 mg twice daily, adding hydrochlorothiazide 12.5 mg once daily, adding doxazosin 4 mg once daily, and increasing hydrochlorothiazide to 25 mg once daily. Participants taking two antihypertensive drugs before washout will generally start with eplerenone plus amlodipine. Treatment adjustments will depend on blood pressure, tolerability, and safety assessments, with a target seated office blood pressure below 140/90 mmHg. Treatment will continue for 24 weeks.
药品：Eplerenone

Eplerenone will be administered orally at 50 mg once daily as the initial treatment in the experimental arm. The dose may be increased to 50 mg twice daily according to the prespecified treatment algorithm, blood pressure response, tolerability, serum potassium, and kidney function. Treatment will continue for 24 weeks, with dose reduction or interruption when clinically indicated.
有源比较器：Standard Treatment

Participants will receive stepped antihypertensive treatment starting with telmisartan 40 mg orally once daily. Treatment will be intensified as needed by sequentially adding amlodipine 5 mg once daily, increasing telmisartan to 80 mg once daily, increasing amlodipine to 5 mg twice daily, adding hydrochlorothiazide 12.5 mg once daily, adding doxazosin 4 mg once daily, and increasing hydrochlorothiazide to 25 mg once daily. Participants taking two antihypertensive drugs before washout will generally start with telmisartan plus amlodipine. Treatment adjustments will depend on blood pressure, tolerability, and safety assessments, with a target seated office blood pressure below 140/90 mmHg. Treatment will continue for 24 weeks.
药品：Telmisartan

Telmisartan will be administered orally at 40 mg once daily as the initial treatment in the active comparator arm. The dose may be increased to 80 mg once daily according to the prespecified treatment algorithm, blood pressure response, and tolerability. Treatment will continue for 24 weeks, with dose reduction or interruption when clinically indicated.

大体时间
Change From Baseline in Mean Daytime Ambulatory Systolic Blood Pressure at Week 12
大体时间：Baseline and Week 12

Change in mean daytime systolic blood pressure, measured in mmHg by 24-hour ambulatory blood pressure monitoring, from baseline to Week 12. Mean daytime systolic blood pressure is the average of all valid daytime systolic readings. A valid recording requires at least 70% of scheduled readings, including at least 20 daytime readings and 7 nighttime readings. Change is calculated as the Week 12 value minus the baseline value; a negative value indicates a reduction in blood pressure.
