Abstract
The present invention relates to rusalatide acetate compositions, formulations and dosage forms that include 23 amino acid monomer (“Monomer”), dimer (“Dimer”) of two 23 amino acid Monomers, or any combination of Monomer and Dimer, wherein any ratio, proportion or percentage of Monomer and Dimer may be present in the compositions, formulations and dosage forms. The invention also broadly covers stable compositions, formulations or dosage forms that include rusalatide acetate and any pharmaceutically acceptable salts thereof.
Claims2
A stable polypeptide composition comprising:
- (a) a 23 amino acid polypeptide comprising Ala-Gly-Tyr-Lys-Pro-Asp-Glu-Gly-Lys-Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val (SEQ ID NO:
- 1), the polypeptide having been synthesized and purified according to Good Manufacturing Practice (GMP) requirements,
- (b) a peptide dimer comprising two polypeptides, each with the amino acid sequence Ala-Gly-Tyr-Lys-Pro-Asp-Glu-Gly-Lys-Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val (SEQ ID NO:1), wherein the two polypeptides are covalently linked by a disulfide bond, and
- (c) an aqueous carrier, wherein the carrier comprises glycerol and water,
- further wherein the composition comprises chitosan,
- further wherein the composition comprises polyvinylpyrrolidone,
- further wherein the composition comprises polyethylene glycol,
- further wherein the composition comprises trehalose,
- further wherein the composition comprises xanthan gum,
- further wherein the composition comprises guar gum,
- further wherein the composition comprises sodium alginate,
- further wherein the composition comprises calcium trisodium diethylenetriaminepentaacetic acid,
- further wherein the composition is a single use liquid dosage form,
- further wherein the composition has a purity of at least ninety percent,
- further wherein the composition is at least ninety percent free of reactive oxygen species, endotoxins,
- organic solvents, degradation impurities, and redox-active transition metal impurities.
