Differential Vascular and Endocrine Effects of Valsartan/Sacubitril in Heart Failure With Reduced Ejection Fraction — VASCEND  

Heart Failure Clinical Trial

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

Clinical Trial Summary

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.

Clinical Trial 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. ;
