Maintenance of protein stability during manufacture, storage, and delivery is necessary for the successful development of a drug product. Herein, the utility of two compatible solutes—ectoine and hydroxyectoine—in stabilizing a model protein labeled Fab2 has been investigated. Specifically, the performance of ectoine and hydroxyectoine in stabilizing Fab2 in a spray-dried formulation at elevated temperature and after multiple freeze/thaw cycles has been compared with the performance of a formulation containing trehalose and a formulation containing no excipient as controls. In the solid state at 90 and 37 °C and in freeze concentrate systems, ectoine and hydroxyectoine suppress protein aggregation. Like trehalose, hydroxyectoine also limits N-terminal pyroglutamate formation in Fab2 in the solid state. The extent of protein stabilization is dependent on the excipient concentration in the formulation, but at a 1:1 excipient to protein mass ratio, hydroxyectoine is better than trehalose in stabilizing Fab2. The results presented here suggest that ectoine and hydroxyectoine are effective excipients for stabilizing therapeutic antibodies.

在升高的温度下以及在冷冻/融化过程中,喷雾干燥制剂中的依古丁碱和羟合睾酮可稳定抗体。

要成功开发药物产品,必须在制造,储存和运输过程中维持蛋白质的稳定性。在本文中,已经研究了两种相容的溶质-胶质蛋白和羟基胶质蛋白-在稳定标记为Fab2的模型蛋白中的效用。具体地,已经将油桃和羟基油桃在喷雾干燥的制剂中在升高的温度下以及在多次冷冻/解冻循环后稳定Fab 2的性能与含有海藻糖和不含赋形剂的制剂作为对照进行了比较。在90和37°C的固态以及冷冻浓缩系统中,ectoine和hydroxyectoine抑制蛋白质聚集。像海藻糖一样,羟基联苯胺也限制了固态Fab2中N末端焦谷氨酸的形成。蛋白质稳定化的程度取决于制剂中赋形剂的浓度,但在赋形剂与蛋白质的质量比为1:1的情况下,在稳定Fab2方面,羟基外皮优于海藻糖。此处给出的结果表明,ectoine和hydroxyectoine是稳定治疗性抗体的有效赋形剂。
