BACKGROUND AND OBJECTIVES: C.E.R.A., a continuous erythropoietin receptor activator, offers once-monthly dosing without compromising haemoglobin control. This study was undertaken to examine whether monthly C.E.R.A. using pre-filled syringes maintains stable haemoglobin levels when administered according to local clinical judgement. RESEARCH, DESIGN AND METHODS: MIRACEL was a prospective, open-label, single-arm, multicentre study performed at 90 nephrology centres in Germany. After a 2-month screening phase, haemodialysis patients receiving epoetin or darbepoetin were converted to monthly intravenous C.E.R.A., with a 5-month titration phase followed by a 2-month evaluation phase. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov: NCT00413894 RESULTS: Of 661 patients screened, 424 (64.1%) started C.E.R.A. therapy (previous treatment: 72.2% epoetin, 27.8% darbepoetin); 416 were eligible for inclusion in the intent-to-treat population. A mean of two C.E.R.A. dose changes were required during the 7-month treatment period. The primary efficacy variable, haemoglobin within 11-12.5 g/dL or 10-13 g/dL during the evaluation phase, was achieved in 109 (30.8%) and 265 (74.9%) of the 354 evaluable patients, respectively, with no differences observed between patients formerly receiving epoetin or darbepoetin or different dosing frequencies. During the screening, titration and evaluation phases, mean haemoglobin was 11.7 +/- 0.7 g/dL, 11.6 +/- 0.9 g/dL and 11.4 +/- 1.0 g/dL, respectively, and 90.6% (377/416), 70.4% (293/416) and 82.9% (345/416) of patients exhibited < or = 1 g/dL change from phase-specific individual means. C.E.R.A. was well-tolerated with a safety profile similar to that reported in phase III studies. CONCLUSIONS: In this single-arm, open-label, multicentre study, conversion of a large population of haemodialysis patients from epoetin or darbepoetin to monthly C.E.R.A. administration using pre-filled syringes was shown to be practical, convenient and offer good control of haemoglobin levels, regardless of the previous type of therapy or dosing frequency.
