Abstract: Methods of preparing lyophilized preparations of Factor IX which preserve more than 90% of the calcium binding property of Factor IX are disclosed. Factor IX formulated with trehalose shows a superior stability profile after 12 weeks storage at 25° C./60% relative humidity (RH) and 40° C./75% RH relative to Factor IX formulated without trehalose. The data suggest that the inclusion of trehalose in the formulation could allow for temperature excursions or even long-term room temperature storage of a Factor IX lyophilized product. The formulations tested contained 10 mM histidine pH 6.8, 3% mannitol, 66 mM sodium chloride, 0.0075% Polysorbate 80, with and without 1% trehalose. Upon storage at 40° C./75% RH or 25° C./60% RH over 12 weeks the trehalose-containing formulation was comparable to product stored at 2-8° C. while the formulation without trehalose was found to undergo significant aggregation and loss of activity.

Abstract: Gamma globulin concentrates are stabilized against anticomplement activity generation during lyophilization by inclusion in the concentrate of a physiologically acceptable, substantially nonsurface-active hydrophilic macromolecule. The improved concentrates may be safely administered to patients. The main additives to the gamma globulin are a substantially nonsurface-active hydrophilic macromolecule, a protein and a polyol.
