    • 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. The two formulations demonstrated comparable stability over 26 weeks of real time storage at −20° C. and 2-8° C.
    • 公开了制备因子IX的冻干制剂的方法,其保留超过90%的因子IX的钙结合性质。 用海藻糖配制的因子IX在25℃/ 60%相对湿度(RH)和40℃/ 75%RH相对于没有海藻糖配制的因子IX存储12周后显示出优异的稳定性。 该数据表明,在制剂中包含海藻糖可以允许因子Ⅸ冻干产品的温度漂移或甚至长期室温储存。 测试的制剂含有10mM组氨酸pH 6.8,3%甘露醇,66mM氯化钠,0.0075%聚山梨醇酯80,含有和不含1%海藻糖。 在40℃/ 75%RH或25℃/ 60%RH下在12周内储存时,含海藻糖的制剂与2-8℃下储存的产品相当,而没有海藻糖的制剂被发现显着 聚合和失去活动。 这两种配方在-20℃和2-8℃下实时存储26周时表现出可比的稳定性。
