Therapies for chronic renal failure
View Patent ↗The present invention provides methods for the treatment, and pharmaceuticals for use in the treatment, of mammalian subjects in, or at risk of chronic renal failure, or at risk of a need for renal replacement therapy. The methods involve the administration of certain proteins of, or based upon, the osteogenic protein/bone morphogenetic protein (OP/BMP) family within the TGF-β superfamily of proteins.
1. A method of treating a mammal afflicted with a renal condition selected from the group consisting of chronic diabetic nephropathy, diabetic glomerulopathy, diabetic renal hypertrophy, hypertensive nephrosclerosis, hypertensive glomerulosclerosis, renal dysplasia, glomerular hypertrophy, tubular hypertrophy, glomerulosclerosis and tubulointerstitial sclerosis, the method comprising the step of administering to said mammal a therapeutically effective amount of OP-1.
2. The method of claim 1 , wherein the OP-1 comprises a pro form, a mature form, or a soluble form of human OP-1.
3. The method of claim 1 , wherein said renal condition is associated with renal fibrosis.
4. The method of claim 1 , wherein said mammal has less than about 50% of the functional nephron units of a mammal having intact healthy kidneys.
5. The method of claim 1 , wherein said mammal has a GFR which is chronically less than about 50% of a GFRexp for said mammal.
6. The method of claim 1 , wherein said mammal is a human male weighing at least about 50 kg and has a GFR which is chronically less than about 50 ml/min.
7. The method of claim 1 , wherein said mammal is a human female weighing at least about 40 kg and has a GFR which is chronically less than about 40 ml/min.
8. The method of claim 1 , wherein the administration of the OP-1 is parenteral.
9. The method of claim 8 , wherein the administration of the OP-1 is intravenous.
10. The method of claim 8 , wherein the administration of the OP-1 is intraperitoneal.
11. The method of claim 8 , wherein the OP-1 is administered into the renal capsule.
12. The method of claim 8 , wherein a stent has been implanted into the mammal for administration of the OP-1.
13. The method of claim 12 , wherein the stent is an intravenous stent.
14. The method of claim 12 , wherein the stent is an intraperitoneal stent.
15. The method of claim 12 , wherein the stent is an intracapsular stent.
16. The method of claim 1 , wherein the administration of OP-1 is by an implanted device.
