    • Methods and compositions are taught that may be used to administer specific bioactive polypeptides, known as T20 and T1249 to a patient, e.g. , as a method of treating a disease or disease state. In particular, the invention teaches carrier hydrogel composition that contain (a) a polymer material and (b) an effective dose of T20, T1249 or a derivative thereof. The polymer materials used in the carrier hydrogel composition preferably have reverse gelation properties and exist as a liquid, aqueous solution at temperatures below physiological temperatures ( e.g. , below the body temperature of a patient) but form hydrogels under physiological conditions ( e.g. , at temperature at or near the body temperature of a patient). The carrier hydrogel compositions may thus be administered to a patient by injection while they are in a liquid state. Upon administration the carrier hydrogel compositions then form hydrogels with the T20 and/or T1249 polypeptides embedded therein. The T20 and/or T1249 polypeptides are thereby released with improved pharmacokinetic properties and bioavailability. The invention thus provides methods for administering T20 and T1249 polypeptides to a patient by administering the T20 and/or T1249 polypeptides in the carrier hydrogel composition of the invention. Methods of treating various diseases and disease states, particularly HIV infection, are also provided that involve administering an effective dose of T20 and/or T1249 polypeptides to a patient in the carrier hydrogel composition of the invention.
    • 教导了可用于向患者(例如,作为治疗疾病或疾病状态的方法)向特定生物活性多肽(称为T20和T1249)施用的方法和组合物。 特别地,本发明教导了含有(a)聚合物材料和(b)有效剂量的T20,T1249或其衍生物的载体水凝胶组合物。 在载体水凝胶组合物中使用的聚合物材料优选具有反向凝胶化性质并且在低于生理温度(例如,低于患者体温))的温度下以液体,水溶液形式存在,但在生理学上形成水凝胶 条件(例如,,在患者体温或接近体温的温度)。 因此,载体水凝胶组合物可以在液体状态下通过注射施用于患者。 给药后,载体水凝胶组合物然后形成水凝胶,其中嵌入有T20和/或T1249多肽。 由此释放T20和/或T1249多肽,并具有改善的药代动力学性质和生物利用度。 因此,本发明提供了通过在本发明的载体水凝胶组合物中施用T20和/或T1249多肽来向患者施用T20和T1249多肽的方法。 还提供了治疗各种疾病和疾病状态,特别是HIV感染的方法,其涉及向本发明的载体水凝胶组合物中的患者施用有效剂量的T20和/或T1249多肽。
