Abstract

Abstract A method is disclosed for producing an anabolic state in a mammal by co-administration by subcutaneous injection of a combination of effective amounts of IGF-I and an IGF binding protein in a defined molar ratio in the absence of growth hormone so as to produce a greater anabolic response in the mammal than that achieved using IGF-I alone in an amount equal to that used for IGF-I in the combination. Preferably, the IGF-I is native-sequence, mature human IGF-I, the binding protein is IGFBP-3, and the mammal is human or a non-human animal of economic importance such as a cow or pig.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 70 words
A method for producing an anabolic state in a mammal comprising co-administering to the mammal by subcutaneous bolus injection effective amounts of IGFBP-3 and IGF-I in a molar ratio of IGFBP-3 to IGF-I of about 0.5:1 to about 3:1 so as to produce a greater anabolic state in the mammal than that achieved using an equivalent dose of IGF-I alone, wherein growth hormone is not also administered to the mammal.
Claim 2
Independent Claim 70 words
A method for producing an anabolic state in a mammal comprising co-administering to the mammal by subcutaneous bolus injection effective amounts of IGFBP-3 and IGF-I in a molar ratio of IGFBP-3 to IGF-I of about 0.5:1 to about 3:1 so as to produce a greater anabolic state in the mammal than that achieved using an equivalent dose of IGF-I alone, wherein growth hormone is not also administered to the mammal.
Claim 3
Dependent Claim 11 words
The method of claim 1 wherein the mammal is an animal.
Claim 4
Dependent Claim 27 words
The method of claim 2 wherein the IGF-I and IGFBP-3 are bovine, ovine, or porcine IGF-I and IGFBP-3, and the animal is bovine, ovine, or porcine, respectively.
Claim 5
Dependent Claim 11 words
The method of claim 1 wherein the mammal is a human.
Claim 6
Dependent Claim 19 words
The method of claim 4 wherein the IGF-I is human native-sequence, mature IGF-I and the IGFBP-3 is human IGFBP-3.
Claim 7
Dependent Claim 20 words
The method of claim 5 wherein the IGF-I is in a sterile, isotonic solution containing a citrate buffer, pH 6.
Claim 8
Dependent Claim 18 words
The method of claim 5 wherein the molar ratio of IGFBP-3 to IGF-I is about 0.8:1 to 1.5:1.
Claim 9
Dependent Claim 28 words
The method of claim 4 wherein the IGF-I is a human native-sequence IGF-I analog having the glutamic acid at position 3 replaced by another amino acid or deleted.
Claim 10
Dependent Claim 10 words
The method of claim 8 wherein the IGF-I is des(1-3)-IGF-I.
Claim 11
Dependent Claim 21 words
The method of claim 9 wherein the des(1-3)-IGF-I is in a sterile, isotonic solution containing acetic acid, pH 3.2 to 4.5.
Claim 12
Dependent Claim 11 words
The method of claim 8 wherein the IGFBP-3 is human IGFBP-3.
Claim 13
Dependent Claim 16 words
The method of claim 1 wherein the effective amount of IGF-I is at least 0.1 mg/kg/day.
Claim 14
Dependent Claim 14 words
The method of claim 4 wherein the effective amount of IGF-I is 1-20 mg/kg/day.
Claim 15
Dependent Claim 34 words
The method of claim 4 wherein the human to be treated has reached a maximum growth level and then a decrease in annualized growth rate after having previously been treated with growth hormone alone.
Claim 16
Dependent Claim 26 words
The method of claim 4 wherein the human to be treated is at an age that is 2-3 years before his or her growth plate closes.
Claim 17
Dependent Claim 25 words
The method of claim 4 wherein the effective amount of IGF-I is less than the dose that gives a maximal growth response using IGF-I alone.
Claim 18
Dependent Claim 15 words
The method of claim 4 wherein the human to be treated is a pregnant woman.
