Compositions and methods for treating heart failure
View Patent ↗The present invention provides methods for treating chronic heart failure patients using the medication comprising neuregulin. The methods comprise first performing a companion diagnostic test of each patient before treatment; and then providing a suitable treatment to the patient according to the results of the companion diagnostic test. When the result of the test is within a favorite treatment zone, the patient is suitable for heart failure treatment by administering an effective amount of neuregulin.
1 . A method of treating a heart failure patient by neuregulin 1, the method comprising administering neuregulin 1 at an amount of 0.6 or 1.2 ug/kg to the heart failure patient; wherein the patient has been identified for treatment by neuregulin 1 based on a companion diagnostic test; wherein the neuregulin 1 comprises the amino acid sequence of SEQ ID NO: 1.
2 . The method of claim 1 , wherein the companion diagnostic test measures the plasma level of NT-proBNP in the patient.
3 . The method of claim 2 , wherein the result of the test is indicative for the treatment by neuregulin 1 when the plasma level of NT-proBNP≤4000 fmol/ml.
4 . The method of claim 2 , wherein the result of the test is indicative for the treatment by neuregulin 1 when the plasma level of NT-proBNP is between 1600 fmol/ml and 4000 fmol/ml.
5 . The method of claim 2 , wherein the result of the test is indicative for the treatment by neuregulin 1 when the plasma level of NT-proBNP is ≤1600 fmol/ml.
6 . The method of claim 2 , wherein the plasma level is measured by immunoassay.
7 . The method of claim 1 , wherein the companion diagnostic test is evaluating heart function by NYHA heart function classification.
8 . The method of claim 2 , wherein the result of the test is indicative for the treatment by neuregulin 1 when the heart function is NYHA class II or III.
