OPTIMIZED RATIOS OF AMINO ACIDS AND SUGARS AS AMORPHOUS STABILIZING COMPOUNDS IN PHARMACEUTICAL COMPOSITIONS CONTAINING HIGH CONCENTRATIONS OF PROTEIN-BASED THERAPEUTIC AGENTS
The present invention relates to improved pharmaceutical compositions that contain high concentrations of one or more protein biomolecule(s). In particular, the invention relates to pharmaceutical compositions that include an optimized ratio of protein biomolecule to an amorphous stabilizing compound or compounds, especially a sugar, such as sucrose, trehalose, glucose, lactose or sorbitol, or mixtures thereof, or one or more amino acid molecules such as arginine, alanine, glycine, lysine or proline, or derivatives and salts thereof, or mixtures thereof. The inclusion of such amorphous stabilizing compound(s), at such optimized ratio, provides acceptable long-term stability of the protein biomolecule, and facilitates shorter lyophilization time, more specifically shorter drying time, even more specifically shorter primary drying time.
