Abstract

The present invention provides, among other things, stable formulations comprising an anti-Interleukin 1 Receptor 1 (IL1R1) antibody at a concentration of between than 50-200 mg/ml, wherein the formulation comprises less than 130 mM arginine and a pH of 4.4-6.5, wherein the amount of HMW species in the formulation increases less than 2% upon storage at 25° C. for at least 4 weeks.

Claims (27)

1 . A stable formulation comprising an anti-interleukin-1 receptor 1 (IL1R1) antibody,

wherein the formulation comprises less than 130 mM arginine, a buffer and a pH of 4.4-6.5,

wherein the anti-IL1R1 antibody comprises a HCDR1 of SEQ ID NO: 5 (FHWIA), a HCDR2 of SEQ ID NO: 6 (IIHPGASDTRYSPSFQG), a HCDR3 of SEQ ID NO: 7 (QRELDYFDY), a LCDR1 of SEQ ID NO: 8 (RASQSIGSSLH), a LCDR2 of SEQ ID NO: 9 (YASQSFS), and a LCDR3 of SEQ ID NO: 10 (HQSSSLPLT), and

wherein the anti-IL1R1 antibody is present at a concentration of 50-200 mg/ml.

2 . The stable formulation of claim 1 , wherein the formulation comprises less than 67 mM arginine.

3 . The stable formulation of claim 1 , wherein the formulation is substantially free of arginine.

4 . The stable formulation of claim 1 , wherein the anti-IL1R1 antibody is present at a concentration of 100-165 mg/ml.

5 . The stable formulation of claim 4 , wherein the anti-IL1R1 antibody is present at a concentration of 150 mg/ml.

6 . The stable formulation of claim 1 , wherein the buffer is present at a concentration of 15 mM to 75 mM.

7 . The stable formulation of claim 5 , wherein the buffer comprises 25 mM sodium acetate.

8 . The stable formulation of claim 1 , wherein the pH is 4.6-5.7.
