Mean Change in Hb Concentration Between Baseline and the Efficacy Evaluation Period [ Time Frame: From Baseline (Week 0) to EEP (Week 29 to Week 36) ]
Mean change in Hb concentration was calculated as the difference between the time adjusted average of Hb during the efficacy evaluation period (EEP [Week 29 to Week 36]), and the Hb at Baseline (Week 0). A positive change from baseline indicates improvement.

  • Mean Time to Achievement of Response During the EEP [ Time Frame: From Week 29 to Week 36 ]
    Participants with Hb concentrations within target range of 10-12 g/dl were considered to be responders. Mean time to achievement of response during the EEP (Week 29 to Week 36) is presented.

    The percentage of participants whose Hb Concentrations remained within the target range of 10.0- 12.0 g/dL throughout the EEP (Week 29 to Week 36) is presented.
  • Mean Time Spent by Participants in the Target Range of 10.0- 12.0 g/dL During the EEP [ Time Frame: From Week 29 to Week 36 ]
    Mean time spent by participants in the target range of 10.0- 12.0 g/dL during the EEP (Week 29 to Week 36) is presented.
  • Percentage of Participants Requiring Dose Adjustments During Dose Titration Period and EEP [ Time Frame: Weeks 0 to Week 36 ]
    Percentage of participants requiring dose adjustments during dose titration period (DTP [Week 0 to Week 28]) and EEP (Week 29 to Week 36) is presented. The dose adjustments (increase or decrease) were required: if a single Hb concentration was either ≥ 13 g/dL or < 9 g/dL; if the difference of 2 consecutive Hb concentrations was ≥2 g/dL; if the values of scheduled Hb assessments on the day of administration of C.E.R.A. and on the previous study visit were both out of range of 10 to 12 g/dL; if the values of the scheduled Hb assessments on the day of administration of C.E.R.A. and on the previous study visit were both out of the range 10.5 to 11.5 g/dL. Dose adjustment could be made at any time at the discretion of the clinician if clinically warranted.
  • Number of Participants Who Received Red Blood Cell Transfusions During the Study Period [ Time Frame: Up to Week 52 ]
    Red blood cell transfusions were given during the treatment period in case of medical need. Blood transfusions occurred during the DTP (Week 0 to Week 28), EEP (Week 29 to Week 36), and during the long term safety period (LSTP [Week 37 to Week 52]) are presented.
  • Number of Participants Who Experienced Any Adverse Events or Serious Adverse Events [ Time Frame: Up to Week 52 ]
    An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. 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.

A Single Arm, Open Label Study to Assess the Efficacy, Safety and Tolerability of Once-monthly Administration of Subcutaneous C.E.R.A. for the Treatment of Chronic Renal Anaemia in Pre-dialysis Patients Not Currently Treated With ESA.
This single arm study will assess the efficacy and safety of subcutaneous methoxy polyethylene glycol-epoetin beta (Mircera) for the correction and maintenance of hemoglobin levels in predialysis patients with renal anemia who are not currently treated with erythropoietin stimulating agents (ESA). Eligible patients will receive monthly subcutaneous injections of Mircera at an initial recommended dose of 1.2 micrograms/kg. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
