Trial Outcomes & Findings for A Study of Monthly Subcutaneous Mircera for the Treatment of Chronic Renal Anemia in Predialysis Patients Not Treated With ESA. (NCT NCT00661388)

NCT ID: NCT00661388

Last Updated: 2025-09-11

Results Overview

Mean change in Hb concentration was calculated as the difference between the time adjusted average of Hb during the efficacy evaluation period (EEP \[Week 29 to Week 36\]), and the Hb at Baseline (Week 0). A positive change from baseline indicates improvement.

Measure
C.E.R.A
Eligible participants were administered continuous erythropoietin receptor activator (C.E.R.A) subcutaneously, every 4 weeks for 44 weeks. The initial dose of C.E.R.A. was 1.2 micrograms (mcg)/kilogram (kg). Subsequent doses were adjusted to maintain the individual participant's hemoglobin (Hb) within the target range of 10.0 and 12.0 grams (g)/ deciliter (dL).

An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.

SECONDARY outcome

Timeframe: Baseline (Week 0), Weeks 8, 16, 32, 40

Population: Safety population included all participants who received at least one dose of the trial medication and underwent a safety follow-up, whether withdrawn prematurely or not. Number of participants analyzed at a particular visit is determined by 'n'.

Mean change from Baseline in creatinine concentration was calculated as the difference between Baseline and post-baseline measurements. It was recorded for each participant at enrollment (Week 0) and at different time points during the study up to Week 48.
