简要总结
This is a randomized, double-blind, multicenter clinical phase III study involving about 105 cancer patients aged >18 years who are receiving palliative chemotherapy and who are suffering from chemotherapy associated anemia. A standard treatment group (ERYPO®) will be included to provide a reference reflecting current standard medical practice.
详细描述
Eligible patients were randomized to one of two different treatment groups (EPO HEXAL or ERYPO) in a 2:1 ratio. Patients received double-blind treatment for a period of 12 weeks. Following randomization the patients were treated subcutaneously with a dose of 150 IU/kg body weight of study drug three times per week. Dose adjustments to 300 IU/kg body weight three times per week were to be done if hemoglobin (Hb) increased <1.0 g/dL or the reticulocyte count increased <40,000 /μl after 4 weeks or if Hb increased <2.0 g/dL after 8 weeks of treatment. The primary endpoint was the Hb response in the EPO HEXAL group during weeks 5-12 of the study defined as absolute increase in Hb value of 2.0 g/dL from the mean value of the screening/baseline period in the absence of red blood cell transfusion during the preceding 4 weeks. For that purpose, Hb levels were measured at the weekly study visits by a central laboratory. Further parameters of treatment efficacy, safety and tolerability were recorded.

研究组 & 干预措施
HX575 epoetin alfa Hexal AG
HX575 (erythropoietin alfa of the Sponsor Hexal AG). Eligible patients to be randomized in ratio 2:1 and to be subcutaneously treated (solution for injection (s.c.)) for 12 weeks with HX575 in pre-filled syringes. The maximum weekly dose of HX575 was 300 IU/kg body weight to maintain hemoglobin levels in the therapeutic range. Application of the drug required at least once per week and allowed maximum three times per week.
