摘要:
The present invention provides, among other things, pre-lyophilization formulations, reconstituted formulations, and lyophilate powder compositions comprising a Factor IX (FIX) polypeptide. The present invention also provides lyophilization methods for producing lyophilate powder comprising a FIX polypeptide. The present invention is directed to a pre-lyophilization formulation comprising: (a) a Factor IX (FIX) polypeptide having FIX coagulation activity; (b) a buffering agent; (c) a stabilizing agent; (d) a bulking agent; and (e) a surfactant, wherein the formulation has a fill volume of less than about 5 mL,and wherein each of (a)-(e) are at an amount per vial (mg/vial) Empty Vials sufficient to allow (1) improved stability of the FIX polypeptide when lyophilized.
