Liquid pharmaceutical formulations for injection comprising thiamine pyrophosphate 1-(3-aminopropyl)-2-methyl-1H-imidazole and uses thereof
Concentrated, low-viscosity, low-volume liquid pharmaceutical formulations of proteins have been developed. Such formulations can be rapidly and conveniently administered by subcutaneous (SC) or intramuscular (IM) injection, rather than by lengthy intravenous infusion. These formulations include low-molecular-weight and/or high-molecular-weight proteins, such as mAbs, and organophosphates. The viscosity of the formulation is significantly reduced by the addition of one or more organophosphates.

(ii) about 0.02 M to about 0.30 M thiamine pyrophosphate 1-(3-aminopropyl)-2-methyl-1H-imidazole (TPP-APMI); and
(iii) a pharmaceutically acceptable solvent;
wherein the liquid pharmaceutical formulation, when in a volume suitable for injection, has an absolute viscosity of from about 1 cP to about 100 cP at 25° C. as measured using a cone and plate viscometer or a microfluidic viscometer; and the absolute viscosity of the liquid pharmaceutical formulation is less than an absolute viscosity of a control composition comprising the antibody, a buffer in place of the TPP-APMI, and the pharmaceutically acceptable solvent; and
wherein the absolute viscosity is an extrapolated zero-shear viscosity.

The method of claim 11 , wherein the injecting has an injection force that is at least 10% less than an injection force for a control composition, the control composition comprising the antibody and the pharmaceutically acceptable solvent, but without the TPP-APMI, when administered in the same way as the liquid pharmaceutical formulation.
14. The method of claim 11 , wherein the injecting is performed with a needle between 27 and 31 gauge in diameter.
15. A method of preparing the liquid pharmaceutical formulation of claim 1 comprising the step of combining the antibody, the pharmaceutically acceptable solvent, and the TPP-APMI.
