The present invention is directed to stabilized insulin composition comprising a mixture of insulin species such as insulin and an insulin analog. As disclosed herein, insulin compositions comprising a mixture of insulin and insulin analog species form heterodimeric complexes having a greater stability than the homodimeric complexes formed in compositions comprising single insulin species. Consequently, the present invention provides methods for stabilizing insulin molecules, methods for identifying stable heterodimeric insulin complexes and stabilized insulin compositions.

The present invention relates to insulin crystals formed from zinc, protamine, a hexamer-stabilizing compound, and a polypeptide selected from the group consisting of insulin, an insulin analog, and a derivatized insulin. The crystals are suitable for administering to a patient for control of blood glucose levels. The crystals have been derived from the neutral protamine Hagedorn (NPH) form in a process utilizing precisely determined protamine concentrations and fortification of NPH crystals formed at a first lower concentration of protamine to achieve a second higher concentration of protamine.

The present invention relates to a process for forming non-adsorbed insulin crystals from zinc, protamine, a hexamer-stabilizing compound, and a polypeptide selected from the group consisting of insulin, an insulin analog, a derivatized insulin, and a derivatized insulin analog. The crystals are suitable for administering to a patient for control of blood glucose levels. The crystals are formed in a process utilizing precisely determined protamine concentrations.

Compositions and methods for modulating injection site pain associated with rapid acting injectable insulin formulations have been developed for subcutaneous injection. The formulations contain insulin in combination with a zinc chelator such as ethylenediaminetetraacetic acid (“EDTA”), a dissolution/stabilization agent such as citric acid, a magnesium salt, and, optionally, additional excipients. New presentations include rapid acting concentrated insulin formulations and a way to enhance the absorption of commercially available rapid acting analog formulations by mixing them with a vial containing dry powder excipients that accelerate their absorption. Devices for mixing excipient and insulin together at the time of administration, while minimizing residence time of the mixture, are also described.

The present invention provides a monomeric insulin analog formulation stabilized against aggregation in which the buffering agent is either TRIS or arginine. The stable formulations of the present invention are useful for treating diabetes, and are particularly advantageous in treatment regimes requiring lengthy chemical and physical stability, such as, in continuous infusion systems.

A storage stable formulation comprising an aqueous solution suitable for parenteral delivery, particularly as an injectable formulation to a patient, preferably having a pH of 7.1 to 7.6, containing a fatty acid-acylated insulin or a fatty acid-acylated insulin analog and stabilized using zinc and preferably a phenolic compound.

Disclosed are fusion proteins that include albumin fused to a polypeptide that has insulin activity. The fusion proteins may include albumin fused to insulin or an insulin analog. In particular, the fusions proteins may include albumin fused to a single chain insulin analog. The fusion proteins may exhibit extended insulin activity in vivo or in vitro relative to insulin that is not fused to albumin. The fusion proteins may be formulated as aerosol compositions.

The present invention relates to an insoluble composition comprising an acylated protein selected from the group consisting of acylated insulin, acylated insulin analogs and acylated proinsulin and preparations thereof. The formulations are suitable for parenteral or other delivery to a patient for prolonged control of blood glucose levels. More specifically, the present invention relates to compositions comprising an acylated protein complexed with zinc, protamine and a phenolic compound such that the resulting microcrystals resemble the neutral protamine zinc (NPH) insulin crystalline form. Surprisingly; this acylated protein composition has been found to have therapeutically superior subcutaneous release pharmacokinetics, and longer and flatter glucose kinetics than currently marketed NPH insulin formulations. Furthermore, the crystals of the present invention retain some of the advantageous properties of NPH crystals, namely being able to be easily resuspended and also mixed with soluble insulin.

The invention relates to crystals of an insulin analog in which asparagine (Asn) in position B3 of the B chain is replaced by a naturally occurring basic amino acid residue and at least one amino acid residue in the positions B27, B28 or B29 of the B chain is replaced by another naturally occurring neutral or acidic amino acid residue, where phenylalanine (Phe) in position B1 of the B chain can optionally be absent, the crystals being present in the space group R3 (No. 146) with the cell axes A=81.5 ű1 Å and C=33.3 ű1 Å, their preparation and use, and a pharmaceutical composition comprising these crystals.

The invention relates to a pharmaceutical formulation comprising a polypeptide selected from the group consisting of insulin, an insulin metabolite, an insulin analog, an insulin derivative and combinations thereof; a surfactant or combinations of two or more surfactants; optionally a preservative or combinations of two or more preservatives; and optionally an isotonicizing agent, buffers or further excipients or combinations thereof, the pharmaceutical formulation having a pH in the acidic range.
