  Purpose
This single arm study will assess the efficacy and safety of intravenous Mircera, administered with pre-filled syringes, for the treatment of anemia in patients with chronic kidney disease who are on dialysis, and who have previously received treatment with epoetin alfa or beta or darbepoetin alfa. Patients will receive monthly intravenous injections of Mircera, with the starting dose derived from the dose of epoetin alfa or beta or darbepoetin they were receiving in the week preceding study start. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.

Condition Intervention Phase
Anemia
Drug: methoxy polyethylene glycol-epoetin beta [Mircera]
Phase 3

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open Label Study of the Effect of Intravenous Mircera on Hemoglobin Levels in Anemic Patients With Chronic Kidney Disease Who Are on Dialysis, and Who Have Previously Received Epoetin Alfa or Beta or Darbepoetin Alfa Treatment.

Primary Outcome Measures:
  • Percentage of Participants With Hb Levels Within 11.0-12.5 Grams Per Deciliter (g/dL) During Evaluation Phase [ Time Frame: Visits 8 to 10 (Months 6 to 8) ] [ Designated as safety issue: No ]
  • Percentage of Participants With Hb Levels Within 10.0-13.0 g/dL During Evaluation Phase [ Time Frame: Visits 8 to 10 (Months 6 to 8) ] [ Designated as safety issue: No ]
  • Percentage of Participants With Hb Levels Within 11.0-12.5 g/dL by Dose Modifications During Evaluation Phase [ Time Frame: Visits 8 to 10 (Months 6 to 8) ] [ Designated as safety issue: No ]
    Dose adjustment included increase or decrease in dose. Percentage of participants with Hb levels within 11.0-12.5 g/dL by dose adjustment categories (with dose adjustment and without dose adjustment) were reported.

  • Percentage of Participants With Hemoglobin Levels Within 10.0-13.0 g/dL by Dose Modification During Evaluation Phase [ Time Frame: Visits 8 to 10 (Months 6 to 8) ] [ Designated as safety issue: No ]
    Dose adjustment included increase or decrease in dose. Percentage of participants with Hb levels within 11.0-12.5 g/dL by dose adjustment categories (with dose adjustment and without dose adjustment) were reported.


Secondary Outcome Measures:
  • Percentage of Participants With Hb Levels Within 11.0-12.5 g/dL During Screening Phase [ Time Frame: Visits 1 to 2 (Months -2 to -1) ] [ Designated as safety issue: No ]
  • Percentage of Participants With Hb Levels Within 10.0-13.0 g/dL During Screening Phase [ Time Frame: Visits 1 to 2 (Months -2 to -1) ] [ Designated as safety issue: No ]
  • Percentage of Participants With Hb Levels Within 11.0-12.5 g/dL by Dose Modification During Screening Phase [ Time Frame: Visits 1 to 2 (Months -2 to -1) ] [ Designated as safety issue: No ]
    Dose adjustment included increase or decrease in dose. Percentage of participants with Hb levels within 11.0-12.5 g/dL by dose adjustment categories (with dose adjustment and without dose adjustment) were reported.

  • Percentage of Participants With HbLevels Within 10.0-13.0 g/dL by Dose Modification During Screening Phase [ Time Frame: Visits 1 to 2 (Months -2 to -1) ] [ Designated as safety issue: No ]
    Dose adjustment included increase or decrease in dose. Percentage of participants with Hb levels within 11.0-12.5 g/dL by dose adjustment categories (with dose adjustment and without dose adjustment) were reported.

  • Percentage of Participants With Changes Between Screening and Evaluation Phase With Respect To Hb Levels [ Time Frame: Visits 1 to 2 (Months -2 to -1) and Visits 8 to 10 (Months 6 to 8) ] [ Designated as safety issue: No ]

    Shifts in Hb levels between Screening and Evaluation Phase were classified as follows: Category A: Participants with Hb levels in both Screening and Evaluation Phase within 10-13 g/dL; Category B: Participants who had Hb values within 10-13 g/dL during Screening but shifted outside the range during Evaluation; Category C: Participants who had Hb values outside range during Screening but shifted to stable values (at least within 10 - 13 g/dL) during Evaluation.; Category D: Participants with less than two values available during Evaluation Phase.

    Participants could appear in only 1 category. Participants had to have 2 or 3 values within range (depending on the number of measurements available) to be counted.


  • Percentage of Participants With Hb Fluctuations Within Evaluation Phase [ Time Frame: Visits 8 to 10 (Months 6 to 8) ] [ Designated as safety issue: No ]
    Hb fluctuation was defined as the deviation from individual mean Hb-value within the study phase (Evaluation Phase) and was categorized as less than or equal to (≤) ±1 g/dL, greater than (>) ±1.0 to ±1.5 g/dL, > ±1.5 to ±2.0 g/dL, and > ±2.0 g/dL. Percentage of participants within these deviation categories were reported for Evaluation Phase of the study.

  • Percentage of Participants With Hb Fluctuations Within Screening Phase [ Time Frame: Visits 1 to 2 (Months -2 to -1) ] [ Designated as safety issue: No ]
    Hematology and clinical chemistry were performed partially by a central laboratory as well as by the local laboratories by means of their established methods. Normal ranges and methods as well as quality assurance certificates had to be available to the sponsor prior to the start of the study. Hb fluctuation was defined as the deviation from individual mean Hb-value within the study phase (Screening Phase) and was categorized as ≤ ±1 g/dL, >±1.0 to ±1.5 g/dL, >±1.5 to ±2.0 g/dL, and >±2.0 g/dL. Percentage of participants within these deviation categories are reported for Screening Phase of the study.

  • Percentage of Participants Requiring Erythrocyte Transfusions [ Time Frame: Visits 1 to 10 (Months -2 to 8) ] [ Designated as safety issue: No ]
