This invention relates to stable non-aqueous formulations which are suspensions of proteinaceous substances or nucleic acids in non-aqueous, anhydrous, aprotic, hydrophobic, non-polar vehicles with low reactivity. More specifically, the present invention relates to stable protein or nucleic acid formulations wherein the compound remains in stable, dry powder form, yet the formulation is flowable and, therefore amenable to delivery to an animal via injection, transdermal administration, oral delivery or using an implantable device for sustained delivery. These stable formulations may be stored at elevated temperatures (e.g., 37&deg; C.) for long periods of time and are especially useful as flowable formulations which can be shipped and/or stored at high temperatures or in implantable delivery devices for long term delivery (e.g., 1-12 months or longer) of drug.

Stable protein and nucleic acid formulations using non-aqueous, anhydrous, aprotic, hydrophobic, non-polar vehicles with low reactivity.

This invention relates to stable non-aqueous polar aprotic formulations of peptide compounds. These stable formulations comprise peptide in non-aqueous polar aprotic solvent. They may be stored at elevated temperatures for long periods of time and are especially useful in implantable delivery devices for long term delivery of drug.

Non-aqueous polar aprotic peptide formulations

This invention relates to stable liquid aqueous formulations of peptide compounds at high concentrations. These stable formulations comprise at least about 10% peptide in water. They may be stored at elevated temperatures for long periods of time and are especially useful in implantable delivery devices for long term delivery of drug.

Aqueous formulations of peptides

This invention relates to stable non-aqueous protic formulations of peptide compounds. These stable formulations comprise peptide in non-aqueous protic solvent. They may be stored at elevated temperatures for long periods of time and are especially useful in implantable delivery devices for long term delivery of drug.

Non-aqueous protic peptide formulations

A sustained release delivery system for delivering a beneficial agent is provided. The system includes a reservoir comprising the beneficial agent and a capillary channel in communication with the reservoir and the exterior of the system for delivering the beneficial agent from the system. The capillary channel has a cross-sectional area and a length selected to deliver the beneficial agent at a predetermined rate. The system may further include an outer surface that is impermeable and non-porous during delivery of the beneficial agent. The beneficial agent may be formulated in a glassy sugar matrix.

Diffusional implantable delivery system

This invention relates to stable non-aqueous polar aprotic formulations of peptide compounds. These stable formulations comprise peptide in non- aqueous polar aprotic solvent. They may be stored at elevated temperatures for long periods of time and are especially useful in implantable delivery devices for long term delivery of drug.

Dried proteins are stabilized against loss of biological activity in formulations by adding an reconstitution stabilizer upon rehydration of the dried protein. A kit for producing and a formulation produced by dissolving the dried composition in a solvent containing the reconstitution stabilizer is also described.
