Primary Outcome Measures:
  • Rate of patients who maintain mean Hb concentration in the range of ≥ 10.0g/dL and ≤ 12.0g/dL [ Time Frame: 26 weeks ]

Secondary Outcome Measures:
  • Mean Hb concentration for term of evaluation [ Time Frame: 26 weeks ]
  • The ratio of patients whose Hb concentration reach ≥ 10.0g/dL and increasing amount of Hb concentration reach ≥ 1.0g/dL [ Time Frame: 26 weeks ]
  • Time required for reaching Hb concentration of ≥ 10.0 g/dL and reaching increasing amount of Hb concentration of ≥ 1.0g/dL [ Time Frame: 26 weeks ]
  • Slope of regression line of Hb concentration per week [ Time Frame: 26 weeks ]
  • Variation of QOL [ Time Frame: 26 weeks ]
  • Adverse events [ Time Frame: 26 weeks ]
  • Laboratory measurements [ Time Frame: 26 weeks ]
  • Vital signs, standard 12-lead ECG [ Time Frame: 26 weeks ]
  • Anti-R744 antibody titer [ Time Frame: 26 weeks ]
  • Anti-Epoetin beta antibody titer [ Time Frame: 26 weeks ]
