Abstract

The present invention provides pharmaceutical formulations comprising a human antibody that specifically binds to human interleukin-4 receptor (hIL-4R). The formulations may contain, in addition to an anti-hIL-4R antibody, at least one amino acid, at least one sugar, or at least one non-ionic surfactant. The pharmaceutical formulations of the present invention exhibit a substantial degree of antibody stability after storage for several months.

Claims (37)

1 . A pharmaceutical formulation comprising:

(i) an anti-human interleukin-4 receptor alpha (anti-hIL4Rα) antibody at a concentration of about 100 mg/ml to about 200 mg/ml, wherein the anti-hIL4Rα antibody is a human antibody, wherein the anti-hIL4Rα antibody is an immunoglobulin molecule comprising two heavy chains and two light chains interconnected by disulfide bonds, wherein each heavy chain comprises a heavy chain variable region (HCVR), wherein the HCVR comprises the amino acid sequence of SEQ ID NO: 1, wherein each light chain comprises a light chain variable region (LCVR), wherein the LCVR comprises the amino acid sequence of SEQ ID NO: 5;

(ii) a thermal stabilizer at a concentration from about 0.9%±0.135% w/v to about 10%±1.5% w/v;

(iii) a non-ionic surfactant; and

(iv) arginine at a concentration from about 20 to 100 mM;

wherein the pharmaceutical formulation has a pH from about 5.6 to about 6.2;

wherein the viscosity of the pharmaceutical formulation is less than 35 cPoise; and

wherein less than about 5% of the anti-hIL4Rα antibody recovered from the pharmaceutical formulation after 3 months of storage at 5° C. is aggregated, as determined by size exclusion chromatography.

20 . The pharmaceutical formulation of claim 19 , wherein the non-ionic surfactant is poloxamer 188.

21 . The pharmaceutical formulation of claim 14 , wherein the non-ionic surfactant is a polysorbate.

22 . The pharmaceutical formulation of claim 21 , wherein the polysorbate is polysorbate 20 or polysorbate 80.

23 . The pharmaceutical formulation of claim 22 , wherein the polysorbate 20 or polysorbate 80 is at a concentration of about 0.2% w/v.
