A U.S. Patent for “High Concentration Protein Formulations with Reduced Viscosity” was awarded to the Bhami Research Lab on May 12th, 2020. The present invention is an antibody agent formulation comprising: (i) one or more antibody agents at a concentration between about 10 mg/mL and about 300 mg/mL; and (ii) a viscosity-reducing agent that comprises a combination of nicotinic acid (acid form) and tryptophan, present at a concentration between about 5 mM and about 100 mM each, wherein: the formulation has a viscosity between about 1 cP and about 100 cP when measured at 25.degree. C., using a cone and plate viscometer. Learn More
