Neparvis

Neparvis can only be obtained with a prescription. The medicine is available as tablets and granules to be taken by month twice a day.

For more information about using Neparvis, see the package leaflet or contact your doctor or pharmacist.

The two active substances in Neparvis, sacubitril and valsartan, work in different ways. Sacubitril blocks the breakdown of natriuretic peptides produced in the body. Natriuretic peptides cause sodium and water to pass into the urine thereby reducing the strain on the heart. They also reduce blood pressure and protect the heart from developing fibrosis (scar tissue) that occurs in heart failure.

Valsartan is an ‘angiotensin-II-receptor antagonist’, which means that it blocks the action of a hormone called angiotensin II. The effects of angiotensin II can be harmful in patients with heart failure. By blocking the receptors (targets) to which angiotensin II normally attaches, valsartan stops the hormone’s harmful effects on the heart and also reduces blood pressure by allowing blood vessels to widen.

Neparvis has been shown to be effective at treating heart failure in adults in one main study. In the study, Neparvis was compared to enalapril, another medicine used for heart failure. Patients in the study had long-term heart failure with symptoms of the disease and reduced ejection fraction (the proportion of blood leaving the heart). In the group treated with Neparvis, 21.8% (914 of 4,187) of patients either died as a result of heart and circulation problems or were admitted to hospital with heart failure compared to 26.5% (1,117 of 4,212) of patients treated with enalapril. In general, patients were monitored for about 27 months, during which they took the medicine for about 24 months on average. The study was stopped early because there was compelling evidence that Neparvis was more effective than enalapril.

A study involving children and adolescents showed that the way Neparvis behaves in the body in people below 18 years old is similar to that seen in adults. In addition, Neparvis led to similar reductions across age groups in the blood levels of NT-proBNP. Patients with heart failure have raised levels of NT-proBNP, substances made by the heart. A reduced level of NT-proBNP is associated with a better outcome for patients.

In addition, the study comparing Neparvis with enalapril in 377 patients aged 1 month to below 18 years with heart failure due to systemic left ventricle systolic dysfunction. The main measure of effectiveness was the likelihood of a better outcome after one year of treatment compared with that in the other treatment group (based on the ranking of various events such as death, urgent heart transplant or worsening of symptoms). The results did not show that Neparvis was more effective than enalapril in terms of this measure. However, in both the Neparvis and enalapril groups, there were relevant improvements in symptoms and quality of life measures.

For the full list of side effects and restrictions with Neparvis, see the package leaflet.

The most common side effects with Neparvis in adults (which may affect more than 1 in 10 people) include hyperkalaemia (high blood potassium levels), hypotension (low blood pressure) and renal impairment (kidneys working less well). A potentially severe side effect, angioedema (rapid swelling of deeper skin tissues as well as the tissues around the throat, causing breathing difficulty) can occur uncommonly (in up to 1 in 100 people).

Side effects in children and adolescents are similar to those seen in adults.

Neparvis must not be taken with medicines known as ACE inhibitors (to treat heart failure and high blood pressure) or with medicines containing aliskiren (to treat high blood pressure) in patients who have diabetes or reduced kidney function. It must not be taken by patients who have suffered angioedema, those who have severe liver disease or by women who are pregnant.

Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Neparvis have been included in the summary of product characteristics and the package leaflet.

As for all medicines, data on the use of Neparvis are continuously monitored. Suspected side effects reported with Neparvis are carefully evaluated and any necessary action taken to protect patients.

Neparvis was granted a marketing authorisation valid throughout the European Union on 26 May 2016.

This overview was last updated in 04-2023.

The European Medicines Agency decided that the benefits of Neparvis are greater than its risks and it can be authorised for use in the EU. The main study found that in adults Neparvis reduced deaths from heart and circulation problems or hospital admissions for heart failure. An additional study has shown that Neparvis is expected to provide clinically meaningful benefits to children and adolescents with symptomatic heart failure due to systemic left ventricular dysfunction.

The serious side effects with Neparvis in the main study were similar to those of enalapril, another medicine used for heart failure. Valsartan, one of the active substances in the medicine, is well established for the treatment of high blood pressure and heart failure; its side effects are well known.
