Treatment of bone disorders with skeletal anabolic drugs
Disclosed herein are methods for the prevention and treatment of a variety of mammalian conditions manifested by loss of bone mass, including osteoporosis. The present invention provides methods of using PTHrP, or analogs thereof, for the treatment of metabolic bone disorders that are both effective and have an increased safety.
1. A method of increasing bone mass in a human patient in need thereof, said method comprising administering intermittently to said patient PThrP-(1-36) at a dosage of at least 400 μg/day for a period of at least 3 months, wherein the bone mass density of said patient increases at a rate of at least 1% per month.
2. The method of claim 1 , wherein the bone mass density of said patient increases at a rate of at least 1.5% per month.
3. The method of claim 1 , wherein PTHrP-(1-36) is administered to said patient at a dosage of at least 400 μg/day.
4. The method of claim 1 , wherein PTHrP-(1-36) is administered subcutaneously.
5. The method of claim 1 , wherein said human patient is afflicted with, or at risk of, primary or secondary osteoporosis.
6. The method of claim 1 , wherein said human patient is afflicted with, or at risk of, a metabolic bone disorder selected from the group consisting of: osteomalacla, renal osteodystrophy, and other types of skeletal disorders with associated bone loss.
7. A method of increasing bone mass in a human patient in need thereof, said method comprising administering intermittently to said patient PTHrP-(1-36) at a dose of 400 μg/day for a period of three months, wherein the bone mass density of said patient increases at least 3%.
8. The method of claim 1 , wherein the bone mass density of said patient increases at a rate of at least 4.5%.
9. The method of any one of claims 1 , 2 or 7 , wherein said PTHrP, or an analog thereof, is administered subcutaneously.
10. The method of claim 1 , wherein said human patient is afflicted with, or at risk of, primary or secondary osteoporosis.
11. The method of claim 1 , wherein said human patient is afflicted with, or at risk of, a metabolic bone disorder selected from the group consisting of: osteomalacla, renal osteodystrophy, and other types of skeletal disorders with associated bone loss.
