Mechanisms Underlying Hypotensive Response to ARB/NEP Inhibition - Aim 3

Completed · Phase 4 · Has a placebo group

Conditions studied: Heart Failure

In brief

This is a double-blind, randomized, two x two crossover (aprepitant vs placebo) during both initiation of Entresto, LCZ696, (50 mg dose) and at steady-state of Entresto (200 mg bid dose or the highest tolerated dose).

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Black and white men and women
• Stable patients with a reduced ejection fraction (EF)
• EF ≤55%, and
• history of symptoms of New York Heart Association (NYHA) class I, II, or III heart failure (HF)
• stable clinical symptoms including no hospitalizations for the last three months, or one month if hospitalized only once for initial diagnosis of HF
• who are not already taking LCZ696
• treatment with a stable dose of an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) and with a beta blocker (unless contraindicated or not tolerated) for at least four weeks
• for patients with NYHA Class II or III HF and EF ≤35%, treatment with a stable dose of an mineralocorticoid receptor (MR) antagonist for at least four weeks, unless not possible due to renal function or adverse reaction
• For female subjects, the following conditions must be met:
• postmenopausal status for at least one year
• status post-surgical sterilization
• or if childbearing potential, utilization of barrier methods of birth control or an oral contraceptive and willingness to undergo urine β-HCG testing on every study day
• Age 18 years of age or older

You may not qualify if…

• History of hypersensitivity or allergy to any of the study drugs, drugs of similar chemical classes, ACEi, ARBs, or neutral endopeptidase inhibitor (NEPi), as well as known or suspected contraindications to the study drugs
• History of angioedema
• History of decompensated HF within the last 3 months (exacerbation of chronic HF manifested by signs and symptoms that required intravenous therapy or hospitalization) or one month if hospitalized only once for initial diagnosis of HF
• History of heart transplant or on a transplant list or with left ventricular assistance device
• Symptomatic hypotension and/or a systolic blood pressure (SBP)<100 mmHg at screening or <95 mmHg during the study
• Serum potassium >5.2 mmol/L at screening or during the study
• Impaired renal function (eGFR of <30mL/min/1.73 m2) as determined by the four-variable Modification of Diet in Renal Disease (MDRD) equation, where serum creatinine (Scr) is expressed in mg/dL and age in years:
• a. eGFR (mL/min/1.73 m2)=175 • Scr-1.154 • age-0.203 • (1.212 if Black) • (0.742 if female)
• Acute coronary syndrome, cardiac, carotid, or other major cardiovascular surgery, percutaneous coronary intervention, or carotid angioplasty within six months prior to screening
• Coronary or carotid artery disease likely to require surgical or percutaneous intervention within six months of screening
• History of serious neurologic disease such as cerebral hemorrhage, stroke, seizure, or transient ischemic attack with clinically significant residual deficits
• History of ventricular arrhythmia with syncopal episodes
• Symptomatic bradycardia or second- or third-degree atrioventricular block without a pacemaker
• Presence of hemodynamically significant mitral and/or aortic valve disease, except mitral regurgitation secondary to left ventricular (LV) dilatation
• Presence of other hemodynamically significant obstructive lesions of the LV outflow tract, including aortic and subaortic stenosis
• Type 1 diabetes
• Poorly controlled type 2 diabetes mellitus (T2DM), defined as a HgbA1c >9%
• In T2DM, dipeptidyl peptidase-4 inhibitor use for one month prior to enrollment will be excluded due to possible interaction with LCZ696
• Hematocrit <35%
• Breast feeding and pregnancy
• History or presence of immunological or hematological disorders
• History of malignancy not felt to be cured, except non-melanoma skin cancer
• Diagnosis of asthma requiring use of inhaled beta agonist more than once a week
• History of hypersensitivity reaction to contrast
• Clinically significant gastrointestinal impairment that could interfere with drug absorption
