Study Description
Brief Summary:
This single-arm study will assess the efficacy and safety of intravenous (IV) Mircera when administered for the maintenance of hemoglobin (Hb) levels in participants with chronic renal anemia. Individuals currently receiving maintenance treatment with epoetin alfa or darbepoetin alfa will receive monthly injections of Mircera, with the starting dose (120, 200, or 360 micrograms [mcg] IV injection) derived from the dose of epoetin alfa or darbepoetin alfa they were receiving in the week preceding study start.

Condition or disease Intervention/treatment Phase
Chronic Renal Anemia Drug: Methoxy polyethylene glycol-epoetin beta Phase 3

Arms and Interventions

Arm Intervention/treatment
Experimental: Mircera in Renal Anemia
Participants with chronic renal anemia who have been previously treated with erythropoiesis-stimulating agent (ESA) therapy will receive IV Mircera every 4 weeks for a total of 24 weeks in this single-arm study. The first dose of 120, 200, or 360 mcg will be determined by the dose of ESA received prior to administration of study treatment. Subsequent doses will be adjusted to maintain Hb concentrations within target of 10.5 and 12.5 grams per deciliter (g/dL).
Drug: Methoxy polyethylene glycol-epoetin beta
Participants will receive a starting dose of 120, 200, or 360 mcg via IV injection. Thereafter, the once-monthly dose will be titrated to achieve target Hb concentrations.
Other Name: Mircera/CERA


Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants Who Maintained Average Hb Within Plus/Minus (±) 1 g/dL of Reference Hb and Within Target Range During the Efficacy Evaluation Period (EEP) [ Time Frame: Weeks -4, -3, -2, -1,and 0; pre-dose (0 hours) during Weeks 18, 20, 22, and 24 ]
    Reference Hb was determined individually per participant as the average of all Hb values during a pre-treatment stability assessment (Weeks -4 to 0). During the EEP (Weeks 17 to 24), participants provided a total of four blood samples for Hb monitoring while on treatment with Mircera/CERA. The average Hb during the EEP was calculated per participant and assessed against the reference value. The percentage of participants who had average Hb during the EEP in the target range of 10.5 to 12.5 g/dL and within ±1 g/dL of their individual reference Hb was determined as the primary endpoint. The 95 percent (%) confidence interval (CI) was calculated using the Pearson-Clopper method for exact confidence bounds.


Secondary Outcome Measures :
  1. Mean Change in Time-Adjusted Hb From Baseline to EEP [ Time Frame: At Weeks -4, -3, -2, -1, and 0; pre-dose (0 hours) during Weeks 18, 20, 22, and 24 ]
    Reference Hb was determined individually per participant as the average of all Hb values during a pre-treatment stability assessment (Weeks -4 to 0). During the EEP (Weeks 17 to 24), participants provided a total of four blood samples for Hb monitoring while on treatment with Mircera/CERA. The average Hb during the EEP was calculated per participant and assessed against the reference value. The mean change in Hb value between reference (i.e., "Baseline") Hb and the EEP average Hb was calculated and expressed in g/dL.

  2. Percentage of Participants Whose Hb Remained Within Target Range Throughout the EEP [ Time Frame: Pre-dose (0 hours) during Weeks 18, 20, 22, and 24 ]
    During the EEP (Weeks 17 to 24), participants provided a total of four blood samples for Hb monitoring while on treatment with CERA/Mircera. The percentage of participants who maintained each single Hb measurement in the target range of 10.5 to 12.5 g/dL was determined. The 95% CI was calculated using the Pearson-Clopper method for exact confidence bounds.

  3. Mean Time Spent in the Target Range for Hb During the EEP [ Time Frame: Pre-dose (0 hours) during Weeks 18, 20, 22, and 24 ]
    During the EEP (Weeks 17 to 24), participants provided a total of four blood samples for Hb monitoring while on treatment with Mircera/CERA. Time spent in the target range of 10.5 to 12.5 g/dL was defined as time from first on-target Hb to time of last known on-target Hb, as collected during the EEP. Time spent in the target range was averaged among all participants and expressed in days.

  4. Percentage of Participants Who Required Any Dose Adjustment of Mircera/CERA During the Dose Titration Period (DTP) and EEP [ Time Frame: Weeks 0, 4, 8, 12, 16, 20, and 24 ]
    Study drug administration occurred monthly during the DTP (Weeks 0 to 16), which began with a pre-specified dose of Mircera/CERA according to the dose of ESA administered during Week -1. Subsequent doses could be adjusted throughout the study including during the EEP (Weeks 17 to 24) on the basis of Hb levels or other modification criteria. The percentage of participants who required a dose adjustment for any reason was calculated during the DTP and EEP.

  5. Number of Participants Prematurely Withdrawn From the Study to Receive Blood Transfusion [ Time Frame: Continuously and at every visit from Week 0 (every week until Week 2, thereafter every 2 weeks) through Week 24 ]
    The number of participants who were prematurely withdrawn from the study to receive a blood transfusion during treatment, including the DTP (Weeks 0 and 16) and/or EEP (Weeks 17 to 24), was reported.
