A Study of Intravenous Mircera in Hemodialysis Patients With Chronic Renal Anemia
November 2, 2017 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 Haemodialysis Patients With Chronic Renal Anaemia.
This single arm study will assess the efficacy, safety and tolerability of once-monthly administration of intravenous Mircera for the maintenance of hemoglobin levels in hemodialysis patients with chronic renal anemia.
Patients will receive 4-weekly intravenous injections of Mircera, at a starting dose of 120, 200 or 360 micrograms.
The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Intervention / Treatment |
---|---|
Experimental: C.E.R.A. 120, 200, or 360 mcg
Eligible participants were administered Continuous Erythropoietin Receptor Activator (C.E.R.A.) at a dose of 120, 200, or 360 microgram (mcg), intravenously (IV), every 4 weeks i.e.
Weeks 4, 8, 12, 16 and 20 but not on Weeks 24 and 28.
The initial dose of C.E.R.A.was based on the last dose of the previous Erythropoiesis Stimulating Agent (ESA).
The ESA therapy was administered from enrollment to the 4 weeks stability verification period (SVP), weekly, either as epoetin (<8000 IU, 8000-16000 IU, or >16000 IU) or darbepoetin alpha (<40 mcg, 40-80 mcg, or >80 mcg).
A telephone follow-up visit took place 4 weeks after the end of C.E.R.A. treatment (Week 28).

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Who Maintained Their Mean Hemoglobin Concentration Within +/- 1.0 Gram/Deciliter of Their Reference Hemoglobin Concentration and Between 10.0 and 12.0 Gram/Deciliter During the Efficacy Evaluation Period
Time Frame: EEP (Week 16 to Week 24)
|
The reference hemoglobin (Hb) value was taken as the time adjusted average of all Hb assessments during the SVP (Week -4 to Week 0).
The time adjusted average Hb concentration of all the values recorded during the efficacy evaluation period (EEP) was calculated for each participant and their reference Hb concentration was subtracted from this value.
The percentage of participants maintaining their average Hb concentration during the EEP within +/- 1 gram/deciliter (g/dL) of their reference Hb concentration and between the Hb range 10.0 -12.0 g/dL is presented.
The EEP was defined as Week 16 to Week 24.
Data missing at the end of the EEP was handled using the last value carried forward method, including any data missing due to withdrawal of participants following red blood cells (RBC) transfusion.
