Neuregulin based methods for treating heart failure
View Patent ↗The present invention features methods of treating patients with chronic heart failure by administering a neuregulin polypeptide within a dosage range which is both effective and safe.
1. A method for treating or delaying heart failure in a human subject in need thereof, wherein the method comprises administering to the human subject in need thereof a neuregulin 1 protein at an amount of:
a) 0.3 μg, 0.6 μg, 1.2 μg; or 2.4 μg;
b) 6 EU, 12 EU, 24 EU, or 48 EU;
c) 0.04 nmol, 0.08 nmol, 0.17 nmol, or 0.34 nmol/kg/day.
2. The method of claim 1 , wherein the neuregulin 1 protein is neuregulin 1 β2 isoform.
3. The method of claim 1 , wherein the neuregulin 1 protein comprises the amino acid sequence set forth in SEQ ID NO:1.
4. The method of claim 1 , wherein the neuregulin 1 protein is administered at an amount of 1.2 μg.
5. The method of claim 1 , wherein the neuregulin 1 protein is administered to the human subject intravenously.
6. The method of claim 1 , wherein the neuregulin 1 protein is administered to the human subject for one day or multiple days.
7. The method of claim 1 , wherein the neuregulin 1 protein is administered to the human subject for at least 10 days.
8. The method of claim 1 , wherein the neuregulin 1 protein is administered to the human subject from 10 minutes to 12 hours per day.
9. The method of claim 8 , wherein the neuregulin 1 protein is administered to the human subject 10 hours per day for 10 days.
10. The method of claim 1 , wherein the human subject has or is suspected of having heart failure, wherein the heart failure is caused by one or more ischaemic, congenital, rheumatic, idiopathic, viral or toxic factors.
11. A method for treating or delaying heart failure in a human subject in need thereof, wherein the method comprises administering to the human subject in need thereof a neuregulin 1 protein in an amount of;
a) 0.3 μg, 0.6 μg, 1.2 μg; or 2.4 μg;
b) 6 EU, 12 EU, 24 EU, or 48 EU; or
c) 0.04 nmol, 0.08 nmol, 0.17 nmol, or 0.34 nmol/kg/day, for at least 3 days.
12. The method of claim 11 , wherein said neuregulin 1 protein is administered for at least 5 days.
13. The method of claim 11 , wherein said neuregulin 1 protein is administered for at least 10 days.
14. The method of claim 11 , wherein the neuregulin 1 protein is neuregulin 1 β2 isoform.
15. The method of claim 11 , wherein the neuregulin 1 protein comprises the amino acid sequence set forth in SEQ ID NO:1.
16. The method of claim 11 , wherein the neuregulin 1 protein is administered at an amount of 1.2 μg.
17. The method of claim 11 , wherein the neuregulin 1 protein is administered to the human subject intravenously.
18. The method of claim 17 , wherein the neuregulin 1 protein is administered to the human subject from 10 minutes to 12 hours per day.
19. The method of claim 18 , wherein the neuregulin 1 protein is administered to the human subject 10 hours per day for 10 days.
20. The method of claim 11 , wherein the human subject has or is suspected of having heart failure, wherein said heart failure is caused by one or more ischaemic, congenital, rheumatic, idiopathic, viral or toxic factors.
