The Effect of Neprilysin (LCZ696) on Exercise Tolerance in Patients With Heart Failure (NEPRIExTol)

October 21, 2020 updated by: University of Sao Paulo General Hospital

The Effect of NEPRIlysin (LCZ696) on EXercise TOLerance, Muscle Vasodilatation, Muscle Strength and Body Composition in Patients With Heart Failure - NEPRIExTol-HF Trial

Studies with new drugs in the treatment of heart failure (HF), such as the combination of valsartan/sacubitril, also known as LCZ696, have demonstrated important clinical impact on the morbidity and mortality outcomes in HF population. However, the effect of LCZ696 on the pathophysiological mechanisms of HF such as exercise tolerance (peak VO2) and peripheral muscle blood flow is not known. Since LCZ696 is a new drug with promising effects on the treatment of HF, the objective of the present study will be to evaluate the effect of LCZ696 in patients with HF on: 1) peak VO2, 2) 6-minute walk test, 3) peripheral muscle blood flow, 4) muscle strength, and 5) body composition.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Heart failure (HF) with reduced ventricular ejection fraction is a disease that affects around 5.7 million people in the United States, with a mortality rate of approximately 50% within 5 years. HF is characterized by an exacerbation of the renin-angiotensin-aldosterone system (RAAS), which leads to an increase in sympathetic nerve outflow, peripheral vasoconstriction, and reduced functional capacity. Moreover, many clinical trials have been developed for the treatment of HF patients focused on inhibition of RAAS, such as enalapril. Nevertheless, hospitalization and mortality rates in this population are excessive. However, studies with new drugs, such as the combination of valsartan/sacubitril, also known as LCZ696, have demonstrated important clinical impact on the morbidity and mortality outcomes in HF population. However, the effect of LCZ696 on the pathophysiological mechanisms of HF such as exercise tolerance (peak VO2) and peripheral muscle blood flow is not known. Since LCZ696 is a new drug with promising effects on the treatment of HF, the objective of the present study will be to evaluate the effect of LCZ696 in patients with HF on: 1) peak VO2, 2) 6-minute walk test, 3) peripheral muscle blood flow, 4) muscle strength, and 5) body composition.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)
