A Study of Mircera for the Maintenance Treatment of Participants With Chronic Renal Anemia

February 29, 2016 updated by: Hoffmann-La Roche

A Single Arm, Open Label Study to Assess the Efficacy, Safety, and Tolerability of Once-Monthly Administration of Intravenous C.E.R.A. for the Maintenance of Haemoglobin Levels in Dialysis Patients With Chronic Renal Anaemia

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.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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 Names:
  • Mircera/CERA

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
Weeks -4, -3, -2, -1,and 0; pre-dose (0 hours) during Weeks 18, 20, 22, and 24

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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.
At Weeks -4, -3, -2, -1, and 0; pre-dose (0 hours) during Weeks 18, 20, 22, and 24
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.
Pre-dose (0 hours) during Weeks 18, 20, 22, and 24
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.
Pre-dose (0 hours) during Weeks 18, 20, 22, and 24
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.
Weeks 0, 4, 8, 12, 16, 20, and 24
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.
Continuously and at every visit from Week 0 (every week until Week 2, thereafter every 2 weeks) through Week 24
