Response to epoetin alfa in anemic patients with chronic renal failure is manifested by increased hematocrit, hemoglobin, reduced transfusion requirements and increase in quality of life. Hemoglobin (laboratory haematology parameter) is the primary endpoint of the study .

The intent-to-treat (ITT) population consists of all randomized patients who were exposed to treatment with study drug for at least four weeks and have at least one Hb value available at week 4 or later. Following the intent-to-treat principle, patients are analyzed according to the treatment they were assigned to at randomization.

Mean weekly study drug dose during evaluation period (Week 21-28)

Following the intent-to-treat principle, patients are analyzed according to the treatment they were assigned to at randomization.

Number of patients with positive antidrug antibody (ADA) finding at any time during their treatment period. Count includes 2 patients (1 in each arm) that already had a positive ADA Baseline finding. ADA testing performed by by Radio-Immuno-Precipitation assay. No patient developed neutralizing antibodies.

All patients treated with study drug with a post-baseline antibody assessment
