1. A pharmaceutical formulation comprising:
(i) PEGylated FGF-21 polypeptide comprising the sequence set forth in SEQ ID NO: 2 (PEG-FGF-21) at a concentration of 20 mg/mL;
(ii) histidine at a concentration of 20 mM;
(iii) sucrose at a concentration of 600 mM;
(iv) Polysorbate 80 at a concentration of 0.05% (w/v); and
(v) Diethylenetriaminepentaacetic acid (DTPA) at a concentration of 50 μM;
(vi) wherein the pH is 7.1,
wherein DTPA functions as a structural stabilizer and the formulation exhibits:
(a) a lower rate of PEGylated FGF-21 polypeptide deamidation when stored at 40° C. for about a month with respect to a reference formulation without DTPA;
(b) a lower rate of high molecular weight (HMW) PEGylated FGF-21 polypeptide aggregation when stored at 40° C. for about a month with respect to the reference formulation without DTPA; or
(c) both (a) and (b).
