Stabilized formulations containing anti-interleukin-4 receptor (IL-4R) antibodies
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.

(ii) acetate at a concentration of about 2.5 mM to about 22.5 mM;
(iii) histidine at a concentration of about 10 mM to about 30 mM;
(iv) an organic cosolvent that is a nonionic polymer containing a polyoxyethylene moiety at a concentration of from 0.2% w/v to 1% w/v; and
(v) a sugar or a sugar alcohol at a concentration of about 2.5% w/v to about 10% w/v,
