Trial Outcomes & Findings for A Study of Once Monthly Intravenous Mircera for the Maintenance Treatment of Dialysis Patients With Chronic Renal Anemia. (NCT NCT00737464)

NCT ID: NCT00737464

Last Updated: 2017-12-07

Results Overview

Participants maintaining mean hemoglobin (Hb) concentration within the target range i.e. 10.0 - 12.0 gram per deciliter (g/dL) during last 4 weeks (Weeks 8 to 12) of treatment period (TP) were reported. Total duration for treatment period was 12 weeks. Stability verification period of 2-weeks was conducted before treatment period. The reference Hb concentrations were based upon the mean of the assessments at Weeks -2, -1 and Week 0. The target range for assessment was set at the reference value Hb +/- 1 g/dL but not \>12.0 g/dL and not \<10.0 g/dL.

PRIMARY outcome

Timeframe: Weeks 8 to 12 (Last 4 weeks of treatment period)

Population: Per-protocol (PP) population comprised of participants who had received at least 1 dose of MIRCERA (Week 0) and for whom data for at least one follow-up variable was available and who had completed the study.

Participants maintaining mean hemoglobin (Hb) concentration within the target range i.e. 10.0 - 12.0 gram per deciliter (g/dL) during last 4 weeks (Weeks 8 to 12) of treatment period (TP) were reported. Total duration for treatment period was 12 weeks. Stability verification period of 2-weeks was conducted before treatment period. The reference Hb concentrations were based upon the mean of the assessments at Weeks -2, -1 and Week 0.

Population: Per-protocol (PP) population comprised of participants who had received at least 1 dose of MIRCERA (Week 0) and for whom data for at least one follow-up variable was available and who had completed the study.

The mean change in Hb concentration between reference stability verification period (SVP) and in last 4 weeks (Weeks 8 to 12) of treatment period (TP) was reported. Duration for SVP was 2 weeks followed by treatment period of 12 weeks. The reference Hb concentrations were based upon the mean of the assessments at Weeks -2, -1 and Week 0. The target range for assessment was set at the reference value hemoglobin +/- 1 g/dL but not \>12.0 g/dL and not \<10.0 g/dL.
