Title: Method for inhibiting growth hormone action
Abstract:Human growth hormone variants are disclosed having enhanced affinity for the growth hormone receptor. Also disclosed are human growth hormone variants conjugated to one or more chemical groups, such as poly(ethylene glycol), which is believed to prolong the in vivo half-life of the variants.
Inventor(s): Cunningham; Brian C. (San Bruno, CA), Wells; James A. (Burlingame, CA), Clark; Ross G. (Pacifica, CA), Olson; Kenneth (Burlingame, CA), Fuh; Germaine G. (Pacifica, CA)
Assignee: Genentech, Inc. (South San Francisco, CA)
Filing Date:Feb 24, 1998
Application Number:09/028,648
Claims:1. A method for inhibiting growth hormone action in a patient comprising administering to the patient an effective amount of a human growth hormone variant comprising the following set of amino acid substitutions:

H18A, Q22A, F25A, D26A, Q29A, E65A, K168A, E174A, and further comprising a substitution at G120.

2. The method of claim 1, wherein the patient has acromegaly.

3. The method of claim 1, wherein the patient has a tumor comprising tumor cells expressing receptors that bind human growth hormone.

4. The method of claim 1, wherein the patient has diabetic retinopathy.

5. The method of claim 1 wherein the human growth hormone variant is conjugated to one or more chemical groups that increase the actual molecular weight of the human growth hormone variant to between about 40 and about 100 kilodaltons.

6. The method of claim 5 wherein said chemical group is poly(ethylene glycol).

7. The method of claim 6 where the human growth hormone variant is conjugated to between about four and about six molecules of poly(ethylene glycol).

8. The method of claim 1 wherein the substitution at G120 is selected from G120R, G120K, G120W, G120Y, G120F, and G120E.

9. The method of claim 8 wherein the substitution at G120 is G120K.

10. The method of claim 9 wherein the human growth hormone variant is conjugated to one or more chemical groups that increase the actual molecular weight of the human growth hormone variant to between about 40 and about 100 kilodaltons.

11. The method of claim 10 wherein said chemical group is poly(ethylene glycol).

12. The method of claim 11 where the human growth hormone variant is conjugated to between about four and about six molecules of polyethylene glycol.
