Primary Outcome Measures:
  • To Compare the Efficacy of HX575 Hexal AG and ERYPO® Janssen-Cilag. [ Time Frame: 28 weeks ]
    Primary endpoint was the mean absolute change in Hb level between the screening/baseline and the evaluation period. A two-sided 95 % confidence interval for the difference in mean change (mean of evaluation period - mean of screening/baseline period) in Hb between epoetin alfa HX575 Hexal AG and ERYPO® Janssen-Cilag was computed. The difference was estimated from an analysis of a co-variance model including factors treatment, center, mean baseline Hb (<11.5 and ≥11.5 g/dL) as factors and change of the mean weekly dose from screening/baseline to the evaluation period (of HX575 epoetin alfa Hexal AG or ERYPO® Janssen-Cilag) as a covariate. HX575 Hexal AG was considered at least as good as ERYPO® Janssen-Cilag if the 95 % confidence interval of the difference in mean changes in Hb levels between HX575 Hexal AG and ERYPO® Janssen-Cilag lied entirely within the interval [-0.5 g/dL; 0.5 g/dL]. Primary Endpoint was analyzed based on intent-to-treat (ITT) population.


Secondary Outcome Measures:
  • Mean Absolute Change in Hemoglobin Level From the Screening/Baseline Period to the Evaluation Period - ITT Population [ Time Frame: 28 weeks ]
    The mean absolute change in Hb levels between the screening/baseline period and the evaluation period was analyzed for the intent-to-treat (ITT) population in the same way as the primary efficacy endpoint. A two-sided 95 % confidence interval for the difference in mean change (mean of evaluation period - mean of screening/baseline period) in Hb between HX575 epoetin alfa Hexal AG and ERYPO® Janssen-Cilag was computed. The difference was estimated from an analysis of a co-variance model including factors treatment, center, mean baseline Hb (<11.5 and ≥11.5 g/dL) as factors and change of the mean weekly dose from screening/baseline to the evaluation period (of HX575 epoetin alfa Hexal AG or ERYPO® Janssen-Cilag) as a covariate. HX575 Hexal AG was considered at least as good as ERYPO® Janssen-Cilag if the 95 % confidence interval of the difference in mean changes in Hb levels between HX575 Hexal AG and ERYPO® Janssen-Cilag lied entirely within the interval [-0.5 g/dL; 0.5 g/dL].

Study Completion Date: January 2006
Primary Completion Date: January 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: HX575 epoetin alfa Hexal AG
Eligible patients were switched from the comparator ERYPO®, to epoetin alfa HX575 Hexal AG in ratio 2:1 to be intravenously treated with HX575 in pre-filled syringes for 24 weeks (solution for injection i.v.). The maximum weekly dose was 300 UI/kg body weight (given 1 to 3 times) to maintain hemoglobin levels between 10-13 g/dL.
Drug: HX575 epoetin alfa Hexal AG
HX575 Solution for i.v. injection Containing 1000, 2000 and 4000 IU of rh erythropoietin
Other Name: Binocrit, Abseamed
Active Comparator: ERYPO®, Janssen-Cilag
Eligible patients were randomized and continued to be treated with ERYPO® Janssen-Cilag in pre-filled syringes intravenously (solution for injection i.v.) for 24 weeks. The maximum weekly dose was 300 UI/kg body weight (given 1 to 3 times) to maintain hemoglobin levels between 10-13 g/dL.
Drug: ERYPO®, Janssen-Cilag
Solution for i.v. injection
Other Names:
  • EPREX®
  • Solution for i.v. injection

Detailed Description:
The primary objective of this Phase III study is the evaluation of therapeutic equivalence of HX575 Hexal AG and a comparator of epoetin alfa, ERYPO® in the maintenance intravenous treatment of renal anemia. Efficacy, dosage and safety of HX575 Hexal AG in the long-term treatment were assessed.
