    • Methods for preparing a polymer-based sustained release device including a biocompatible polymer having incorporated therein a biologically active agent are described. In one embodiment, the method of preparing a polymer-based sustained release device comprises the steps of (a) exchanging a continuous medium component of a disperse system, the disperse system including a biologically active agent as a dispersed entity, with an organic liquid, thereby forming a first mixture that includes the biologically active agent and the organic liquid; (b) combining a biocompatible polymer with the first mixture, thereby forming a second mixture that includes the biologically active agent, the organic liquid, and the biocompatible polymer; and (c) separating the organic liquid from the second mixture, thereby forming the polymer-based sustained release device. In one embodiment, the continuous medium component of the disperse system is exchanged with the organic liquid using diafiltration, for example, diafiltration using tangential flow filtration.

    • The invention relates to a sustained release composition and methods of forming and using said composition for the sustained release of biologically active agent. The sustained release compositions of the invention comprise a biocompatible polymer and a biologically active agent characterized by a porous center and a less porous outer layer wherein the center and outer layer consist of essentially the same materials. The sustained release compositions can be prepared by annealing at least a substantial portion of the exterior surface of a polymer/active agent matrix. The compositions which have been annealed exhibit a decrease in the release of agent over the first 24 hours following administration (i.e., reduced burst) and as a result can show an increase in the duration of sustained release thereby providing increased therapeutic benefits.
    • 本发明涉及缓释组合物和形成和使用所述组合物以持续释放生物活性剂的方法。 本发明的持续释放组合物包含生物相容性聚合物和生物活性剂,其特征在于多孔中心和较少多孔外层,其中中心层和外层由基本上相同的材料组成。 持续释放组合物可以通过使至少大部分的聚合物/活性剂基质的外表面退火来制备。 已经退火的组合物在给药后的前24小时表现出试剂释放的降低(即,减少的爆发),结果可以显示持续释放的持续时间的增加,从而提供增加的治疗益处。

    • A method of purifying human growth hormone (hGH) from deamidated hGH, oxidized hGH or both. The method comprises the steps of forming a metal cation complexed-hGH composition enriched in native hGH under conditions wherein none or less than all of the deamidated hGH, oxidized hGH or both complex with a metal cation and, isolating the metal cation-complexed hGH composition from the deamidated hGH, oxidized hGH or combination thereof. The method can further comprise the step of releasing purified hGH from the complex. Alternatively, the metal cation-complexed hGH can be encapsulated into a biocompatible polymer for sustained release of hGH. The purification method can be performed one or more times using the hGH released from the metal cation-complexed hGH composition, depending on the purity of hGH desired.
