Heart Failure With Preserved Ejection Fraction
Conditions
Keywords
Heart Failure, HFpEF, Entresto™, Neprilysin, Diastolic Heart Failure
Brief summary
To determine biomarker responses to Entresto™in patients with Heart Failure with preserved Ejection Fraction (HFpEF) and who have high or low serum neprilysin (NEP) levels.
Detailed description
This is a proof of concept single arm study in which 40 subjects with HFpEF will be assigned to Entresto™ 49/51 mg (sacubitril/valsartan) twice-daily for a total duration of up to 5 weeks of treatment. Blood will be drawn prior to and at completion of treatment. The primary endpoint measured is change in biomarkers with Entresto™ administration that reflect NEP activity and myocardial stress (NT pro-ANP, -BNP, -CNP) and drug action (cGMP). This endpoint has been well validated as a measure of Entresto™ drug response.
Interventions
Entresto™ 49Mg-51 mg will be given twice daily orally for 5 weeks

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Plasma N-terminal Proatrial Natriuretic Peptide (NT proANP) | baseline, 5 weeks | Change in plasma NT pro-ANP value levels as measured in pg/mL. NT-pro ANP means N-terminal polypeptide of ANP (atrial natriuretic peptide) precursor. Natriuretic peptides are substances made by the heart. Elevated levels can mean the heart isn't pumping as much blood the body needs. |
| Change in Plasma N-terminal Pro B-type Natriuretic Peptide (NT-proBNP) | baseline, 5 weeks | Change in plasma NT pro-ANP value levels as measured in pg/mL. Natriuretic peptides are substances made by the heart. Two main types of these substances are brain natriuretic peptide (BNP) and N-terminal pro b-type natriuretic peptide (NT-proBNP). Elevated levels can mean the heart isn't pumping as much blood the body needs. |
| Change in Plasma N-terminal Brain Natriuretic Peptide (BNP) | baseline, 5 weeks | Change in plasma BNP biomarker value levels as measured in pg/mL. Brain natriuretic peptide is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume. Elevated levels can mean the heart isn't pumping as much blood the body needs. |
| Change in Plasma Cyclic Guanine Monophosphate (cGMP) | baseline, 5 weeks | Change in Plasma cGMP biomarker value levels as measured in nmol/L. Cyclic guanosine monophosphate is a cyclic nucleotide derived from guanosine triphosphate. cGMP acts as a second messenger to tissue and cellular responses. |
