Sacubitril/Valsartan Versus Amlodipine in Hypertension and Left Ventricular Hypertrophy.
Study Details
Study Description
Brief Summary
-
Study name: Prospective Comparison of Angiotensin receptor neprilysin inhibitor (ARNI) with Amlodipine on ventricular remodeling in hypertension and left ventricular hypertrophy.
-
Medicine: sacubitril/valsartan (ARNI, 200mg tablet) and the matching placebo; amlodipine (5mg tablet) and the matching placebo.
-
Rationale: according to the results of previous clinical studies, ARNI has obvious advantages in improving cardiac remodeling and reducing blood pressure. However, there is no evidence to demonstrate the efficacy of ARNI in reducing blood pressure and improving ventricular remodeling in hypertension patients with left ventricular hypertrophy (LVH) compared with calcium channel blockers.
-
Objective: to demonstrate the superior efficacy of ARNI on improvement of LVH and blood pressure control compared with amlodipine in hypertension patients with LVH.
-
Study design: This study This is a 24-week prospective, randomized, active-controlled, double-blind, multi-center study, with two equally sized treatment groups: sacubitril/valsartan (200mg tablet); amlodipine (5mg tablet).
-
Study population: men or women aged over 18 years; Untreated patients or patients with taking single antihypertensive drugs; Essential mild to moderate hypertension; Echocardiographic diagnosis of LVH.
-
Randomization and treatment: Eligible patients will be randomly divided into 2 groups, taking one pill of sacubitril/valsartan (200mg tablet) + one pill of matching placebo of amlodipine daily, or one pill of amlodipine (5 mg/tablet) + one pill of matching placebo of sacubitril/valsartan daily.
-
Follow up: after meeting the inclusion criteria, there will be 2-week placebo run-in. Then patients will be randomly assigned into ARNI group and amlodipine group. There will be 5 visiting points in the treatment period, which will be the 4th week, 8th week, 12th week, 18th week and 24th week.
-
Sample size: 120 patients in total.
-
Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in April 2021, recruitment will start. Patients enrollment and follow-up will be performed between June 2021 to June 2022.

-
Study population: men or women aged over 18 years will be screened for hypertension and LVH. Eligible patients should be untreated patients or patients with taking single antihypertensive drugs with essential mild to moderate hypertension (clinic systolic blood pressure ≥ 140 and < 180mmHg), and echocardiographic diagnosis of LVH (LVMI: male≥115g/m2, female≥ 95g/m2). Patients should have abilities to understand the study requirements and provide informed consent.
-
Randomization and treatment: After screening period and run-in period by centers, eligible patients will be randomly divided into 2 groups, taking one pill of sacubitril/valsartan (200mg tablet) + one pill of matching placebo of amlodipine daily, or one pill of amlodipine (5 mg/tablet) + one pill of matching placebo of sacubitril/valsartan daily. At the 12th week of treatment, if systolic blood pressure ≥ 120 mmHg or diastolic blood pressure ≥ 80 mmHg and no safety problems, dosage titration (sacubitril/valsartan 200mg QD to 400mg QD, amlodipine 5mg QD to 10mg QD) should be conducted.
-
Follow up: after meeting the inclusion criteria, there will be 2-week placebo run-in. Clinic blood pressure, ambulatory blood pressure, echocardiography, NT proBNP, myocardial fibrosis index, concomitant medication records and adverse event records will be collected at randomization/the end of run-in period. Then patients will be randomly assigned into ARNI group and amlodipine group. The treatment will be observed for 24 weeks. There will be 5 visiting points in the treatment period, which will be the 4th week, 8th week, 12th week, 18th week and 24th week. Global longitudinal strain (GLS) was detected at randomization, the 12th week and 24th week.
-
Sample size: At least 60 eligible patients should be enrolled in each group, and a total of 120 patients should be enrolled in total.
-
Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in April 2021, recruitment will start. Patients enrollment and follow-up will be performed between June 2021 to June 2022.

At baseline and 24-week follow-up, all patients will undergo standard transthoracic echocardiography performed in the sinus rhythm using the Vivid E9 and E95 Echo-system (General Electric Medical Health, Milwaukee, Wisconsin, USA) equipped with a M5S transducer. LVGLS will be obtained from two-, three-, and four-chamber apical views, and LVGLS analysis will be performed using an offline software (EchoPac, Version 113; General Electric Medical Health).
