Methods of reducing aggregation of IL-1ra
First Claim
1. A method of reducing aggregation of an aggregating interleukin-1 receptor antagonist (IL-1ra) comprising incubating IL-1ra with at least one accessory molecule at a concentration sufficient to reduce aggregation of the IL-1ra or reduce the rate of aggregation of the IL-1ra, wherein at least one of the at least one accessory molecule is selected from a sugar and a multiple-charge anion.

- 1. A method of reducing aggregation of an aggregating interleukin-1 receptor antagonist (IL-1ra) comprising incubating IL-1ra with at least one accessory molecule at a concentration sufficient to reduce aggregation of the IL-1ra or reduce the rate of aggregation of the IL-1ra, wherein at least one of the at least one accessory molecule is selected from a sugar and a multiple-charge anion.
- 10. A method of preparing an interleukin-1 receptor antagonist (IL-1 ra) drug formulation comprising incubating an aggregating IL-1ra with at least one accessory molecule at a concentration sufficient to reduce aggregation of the IL-1ra or reduce the rate of aggregation of the IL-1ra, wherein at least one of the at least one accessory molecule is selected from a sugar and a multiple-charge anion, wherein aggregation is reduced.
- 19. A method of treating a patient comprising administering to the patient a composition comprising (i) a therapeutically effective amount of an aggregating interleukin-1 receptor antagonist (IL-1ra) and (ii) at least one accessory molecule at a concentration sufficient to reduce aggregation of the IL-1ra or reduce the rate of aggregation of the IL-1ra, wherein at least one of the at least one accessory molecule is selected from a sugar and a multiple-charge anion.
- 28. A method of treating a patient having rheumatoid arthritis comprising administering to the patient a composition comprising (i) a therapeutically effective amount of an aggregating interleukin-1 receptor antagonist (IL-1ra) and (ii) at least one accessory molecule at a concentration sufficient to reduce aggregation of the IL-1ra or reduce the rate of aggregation of the IL-1ra, wherein at least one of the at least one accessory molecule is selected from a sugar and a multiple-charge anion.
- 37. A method of treating a patient having osteoarthritis comprising administering to the patient a composition comprising (i) a therapeutically effective amount of an aggregating interleukin-1 receptor antagonist (IL-1ra) and (ii) at least one accessory molecule at a concentration sufficient to reduce aggregation of the IL-1ra or reduce the rate of aggregation of the IL-1ra, wherein at least one of the at least one accessory molecule is selected from a sugar and a multiple-charge anion.
- 46. A pharmaceutical composition comprising an aggregating interleukin-1 receptor antagonist (IL-1ra) and at least one accessory molecule at a concentration sufficient to reduce aggregation of the IL-1ra or reduce the rate of aggregation of the IL-1ra, wherein at least one of the at least one accessory molecule is selected from a sugar and a multiple-charge anion, and wherein aggregation is reduced.
