Methods for increasing and maintaining hematocrit in a mammal comprising administering a hyperglycosylated analog of erythropoietin are disclosed. An analog may be administered less frequently than an equivalent molar amount of recombinant human erythropoietin to obtain a comparable target hematocrit and treat anemia. Alternatively, a lower molar amount of a hyperglycosylated analog may be administered to obtain a comparable target hematrocrit and treat anemia. Also disclosed are new hyperglycosylated erythropoietin analogs, methods of production of the analogs, and compositions comprising the analogs.
本发明公开了提高和维持哺乳动物血细胞比容的方法,包括施用红细胞生成素的高糖基化类似物。与等摩尔量的
重组人促红细胞生成素相比,可减少类似物的给药次数,以获得可比的目标血细胞比容并治疗贫血。另外,也可以施用较低摩尔量的高糖基化类似物,以获得相当的目标血细胞比容和治疗贫血。还公开了新的高糖基化促红细胞生成素类似物、类似物的生产方法和包含类似物的组合物。
