November 3, 2020 updated by: University of Zurich

Differential Vascular and Endocrine Effects of Valsartan/Sacubitril in Heart Failure With Reduced Ejection Fraction: A Double-blind Randomized Controlled Phase IV Trial (VASCEND)

The objective of this study is to evaluate whether valsartan/sacubitril leads to a superior improvement in endothelial function and endocrine status compared to valsartan alone.

Detailed Description

Valsartan/sacubitril (Entresto®; LCZ696) is a first-in-class angiotensin receptor neprilysin inhibitor (ARNI) that has recently been approved for the treatment of chronic heart failure with reduced ejection fraction (HFrEF). The drug consists of a 1:1 complex of the angiotensin receptor blocker (ARB) valsartan and the neprilysin inhibitor sacubitril. In a recent randomized controlled trial in patients with heart failure and reduced ejection fraction (PARADIGM-HF), valsartan/sacubitril significantly reduced all-cause and cardiovascular mortality as well as hospitalizations for heart failure compared to enalapril. The precise reason why combined angiotensin receptor and neprilysin blockade is superior to ACE blockade is still unclear and knowledge of the mechanisms involved would provide further insight which patients with symptomatic heart failure will particularly benefit from valsartan/sacubitril. On the one hand, many of the peptides affected by neprilysin blockade act on vascular endothelial cells. On the other, neprilysin inhibition may induce significant endocrine changes with a shift to more favorable hormonal profile in HFrEF patients. Detailed studies on the vascular and endocrine effects of valsartan/sacubitril in humans are lacking so far. The investigators hypothesize that valsartan/sacubitril results in an incremental improvement of endothelial dysfunction and endocrine imbalance over valsartan in patients with heart failure with reduced ejection fraction.

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)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Measure Description
Time Frame
Difference in flow-mediated vasodilatation (FMD)
Time Frame: Baseline, 3 months
Difference in flow-mediated vasodilatation (FMD, percent dilatation of brachial artery after blood pressure cuff occlusion) between the valsartan/sacubitril and valsartan group as assessed at the final study visit
Baseline, 3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
