Stable formulations of peptides

1. A method for the preparation of a shelf-stable pharmaceutical composition of a GLP-1 compound comprising: dissolving said GLP-1 compound in aqueous medium, adjusting the pH of the solution to between about 8.0 and about 10.5, and heating the solution to a temperature between about 50° C. and about 95° C. for a period of time from about 3 minutes to about 180 minutes to result in a shelf-stable pharmaceutical solution.

2. The method according to claim 1 , wherein the temperature is between 60° C. and 95° C.

3. The method according to claim 1 , wherein the temperature is between 50° C. and 80° C.

4. The method according to claim 1 , wherein the temperature is between 70° C. and 80° C.

5. The method according to claim 1 , wherein the temperature is between 60° C. and 80° C.

6. The method according to claim 1 , wherein the pH is between about 8.0 to 10.0.

7. The method according to claim 1 , wherein the pH is about 8.15.

8. The method according to claim 1 wherein the heating is continued for a period of time which is between 15 minutes and 120 minutes.

9. The method according to claim 1 wherein the heating is continued for a period of time which is between 10 minutes and 90 minutes.

10. The method according to claim 1 wherein the heating is continued for a period of time which is between 3 minutes and 30 minutes.

11. The method according to claim 1 wherein the heating is continued for a period of time which is between 5 minutes and 15 minutes.

12. The method according to claim 1 , further comprising freeze drying the solution after the heating step; wherein the resulting freeze-dried composition is shelf-stable.

13. The method according to claim 1 , further comprising the addition of a pharmaceutically acceptable excipient after the heating step; wherein the resulting pharmaceutical composition is shelf-stable.

14. The method according to claim 1 , wherein said GLP-1 compound is Arg 34 , Lys 26 (N ε -(γ-Glu(N α -hexadecanoyl)))-GLP-1(7-37).
