Patent ID: 7875700

Claim:
A solid complex comprising: an insulin compound conjugate comprising an insulin compound conjugated to a modifying moiety, wherein the modifying moiety comprises from 2 to 10 PEG subunits (OCH 2 —CH 2 ) forming a PEG component coupled to a lipophilic component, where the lipophilic component is selected from the group consisting of alkyls, fatty acids and linear or branched lipids, and either the PEG component or the lipophilic component is coupled to the insulin compound at the B29 amino acid residue; and a cation, wherein the cation is a divalent cation selected from the group consisting of Zn ++ , Mn ++ , Ca ++ , Fe ++ , Ni ++ , Cu ++ , Co ++ and Mg ++ ; where the insulin compound conjugate is complexed with the cation, and wherein the solid complex is a crystalline solid or a rod shaped crystal.
