Primary Outcome Measures:
- Percentage of Participants With an Increase of Greater Than or Equal to 1 Gram Per Decilitre in Hemoglobin Level at Week 8 [ Time Frame: Baseline to Week 8 ]
Therapeutic response was defined as an increase of greater than or equal to (>=) 1 gram per decilitre (g/dL) in hemoglobin (Hb) level as compared to baseline, following 8 weeks of Epoetin beta treatment. The Therapeutic response rate was summarized as percentage of participants with an increase of >= 1 g/dL in Hb level at Week 8 as compared to baseline.
Secondary Outcome Measures:
- Mean Change From Baseline in Hemoglobin Level up to Week 16 [ Time Frame: Baseline, Week 4, Week 8, Week 12, and Week 16 ]
The mean change in Hb concentration was calculated by subtracting the baseline Hb concentration from the Weekly Hb concentration.
- Percentage of Red Blood Cell Transfusion-free Participants [ Time Frame: Up to Week 16 ]
Percentage of participants who have not received red blood cell (RBC) transfusion (packed RBC or whole blood) during the study were reported.
- Number of Participants With or With no Response on Efficacy of Treatment With or Without Iron Replacement Therapy [ Time Frame: Up to Week 16 ]
Effect of individual iron supplementation on the efficacy of Epoetin beta treatment was described by percentage of participants with or with no response on efficacy of treatment due iron replacement therapy. Response was determined by calculating the difference in Hb level at H3 (Week 8) as compared to H1 (baseline). If H3-H1 is greater than (>) 1, there is a response (response value =1), otherwise there was no response (response value=0). If both were missing, then response was also missing. Response value as "1" denotes an effect on the response of treatment with or without iron replacement therapy. Response value as "0" denotes no effect on the response of treatment with or without iron replacement therapy.
- Number of Participants With Adverse Events and Serious Adverse Events [ Time Frame: Up to Week 16 ]
An adverse event (AE) was defined as any untoward medical occurrence in a subject who is administered a study treatment regardless of whether or not the event has a causal relationship with the treatment. An AE, therefore, could be any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the study treatment, whether or not related to the treatment. A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect. Number of participants with at least one AE and SAE were reported.
