The potential role of valsartan + AHU377 ( LCZ696 ) in the treatment of heart failure

Introduction: Heart failure remains a syndrome with a very high mortality rate and a poor quality of life. For patients with heart failure and a preserved ejection fraction (HFpEF), no drugs have shown to improve mortality and morbidity, and therefore novel drugs are highly needed. LCZ696 , a first in class Angiotensin Receptor neprilysin inhibitor (ARNi), might be an interesting novel drug for the treatment of heart failure.

Areas covered: Previous studies have shown promising effects of a combination drug with a neutral endopeptidase and an angiotensin-converting Enzyme inhibitor (omapatrilat) for the treatment of patients with heart failure. However, the occurrence of angioedema prevented the drug from further development. The majority of this paper will discuss the metabolism, pharmacokinetics, pharmacodynamics, clinical effects, and safety of LCZ696, with a particular focus on heart failure.

Expert opinion: LCZ696 is superior to valsartan alone in reducing blood pressure. Preliminary results from a Phase II trial showed that LCZ696 reduced NT-proBNP to a greater extent than valsartan alone, and in addition LCZ696 had beneficial effects on symptoms. With these promising first results, the results of ongoing further studies in heart failure are eagerly awaited.
