FORMULATIONS OF GLUCAGON-LIKE-PEPTIDE-2 (GLP-2) ANALOGUES

Abstract:

Liquid formulations of GLP-2 analogues that make them suitable for long term storage as liquids and/or that makes them especially suitable for delivery by a drug delivery device are described. Solid compositions comprising acetate salts of glucagon-like peptide 2 (GLP-2) analogues useful for making the liquid formulations are also described. The development of these liquid formulations is based on the finding that acetate present in the formulation that originates from the GLP-2 analogues has an effect on the viscosity of the formulation, that during long term storage at 2-8.degree. C. of GLP-2 analogues, the concentration dependence for covalent oligomer formation is inversely dependent on increasing concentration of the GLP-2 analogue, and that GLP-2 analogues used in the formulations are not compatible with phosphate buffer commonly used in the prior art to reconstituted powdered or lyophilized GLP-2 compositions.
