Inventor(s):	Srikanth Sundaram, Daniel Charles Stewart
Assignee:	Maia Pharmaceuticals Inc
Application Number:	US17/934,901
Patent Claims:	1. A method for administering bortezomib to a patient in need thereof, comprising intravenously administering to the patient a liquid, ready-to-use aqueous composition consisting of about 1 mg/mL bortezomib, about 10 mg/mL mannitol, about 20 mg/mL dimethyl sulfoxide, about 0.82 mg/mL sodium acetate, water and, optionally, hydrochloric acid, sodium hydroxide, or a combination thereof, wherein the ready-to-use composition is prepared by a process comprising adding a first solution of bortezomib dissolved in dimethyl sulfoxide to a second solution comprising mannitol, sodium acetate, and water, wherein the pH of the ready-to-use composition is about 5 to about 6. 2. The method of claim 1, wherein the composition has a pH of about 5.5 to about 6. 3. The method of claim 1, further comprising filling the liquid composition in a vial, freezing the liquid composition in the vial, evacuating the head space in the vial, filling the head space with nitrogen, stoppering the vial, and thawing the vial. 4. The method of claim 1, wherein the patient suffers from cancer. 5. The method of claim 1, wherein the patient suffers from multiple myeloma. 6. The method of claim 1, wherein the patient suffers from mantle cell lymphoma. 7. A method for administering bortezomib to a patient in need thereof, comprising intravenously administering to the patient a liquid, ready-to-use aqueous composition consisting of about 2.5 mg/mL bortezomib, about 25 mg/mL mannitol, about 22 mg/mL dimethyl sulfoxide, about 0.82 mg/mL sodium acetate, water and, optionally, hydrochloric acid, sodium hydroxide, or a combination thereof, wherein the ready-to-use composition is prepared by a process comprising adding a first solution of bortezomib dissolved in dimethyl sulfoxide to a second solution comprising mannitol, sodium acetate, and water, wherein the pH of the ready-to-use composition is about 5 to about 6. 8. The method of claim 7, wherein the composition has a pH of about 5.25 to about 5.75. 9. The method of claim 7, further comprising filling the liquid composition in a vial, freezing the liquid composition in the vial, evacuating the head space in the vial, filling the head space with nitrogen, stoppering the vial, and thawing the vial. 10. The method of claim 7, wherein the patient suffers from cancer. 11. The method of claim 7, wherein the patient suffers from multiple myeloma. 12. The method of claim 7, wherein the patient suffers from mantle cell lymphoma.
