Measure
C.E.R.A.
Participants with chronic renal anemia Stage III-IV, not on dialysis, were administered C.E.R.A. according to routine clinical practice and were followed for the treatment duration of 24 weeks (6 months). Dosing and titration of C.E.R.A. treatment was at the discretion of the investigator in accordance with local clinical practice or prescribing information. Dosing instructions as per the local label were - For correction of anemia: 0.6 mcg/kg of C.E.R.A. once every two weeks, and for Maintenance of Hb levels: Conversion to C.E.R.A. dose (120, 200, or 360 mcg either once monthly; or 60, 100, or 180 mcg once every 2 weeks) depending on the previous weekly epoetin or darbepoetin dose.

PRIMARY outcome

Timeframe: Up to Week 24

Population: The intent-to-treat (ITT) population included all participants who received at least 1 dose of C.E.R.A. (Week 0), for whom data for at least one follow-up variable was available, and who did not have a major protocol violation. The participants who achieved target Hb range (10-12 g/dL) were included in the analysis.

Correction of anemia was evaluated in participants with Hb \< 10 gram/deciliter (g/dL). Hemoglobin levels were recorded for each participant at enrollment and at different time points during the study up to Week 24. The mean time required to achieve target Hb range (10-12 g/dL) was calculated using the following formula: Time to achieve target range = (Date of Hb evaluation when participant achieves target range at first time - visit date of first dosing) + 1.

PRIMARY outcome

Timeframe: Up to Week 24

Population: The ITT population was the anticipated population for analysis.

Maintenance of Hb levels was to be evaluated for participants on Erythropoiesis stimulating agent (ESA) with Hb levels 10-12 g/dL. None of the participants in the enrolled population had received treatment with other ESAs and had pre-therapy Hb level as 10 g/dL or above. Therefore, the percentage of participants who had received treatment with other ESAs and were maintaining Hb level within 1 g/dL of baseline value during the study could not be evaluated. Baseline is defined as Week 0.

Correction of anemia was evaluated in participants with Hb \< 10 g/dL at enrollment. Hemoglobin levels were recorded for each participant at enrollment and at different time points during the study up to Week 24.

Timeframe: Up to Week 24

Population: The safety population was defined as all participants entered into the study.

An adverse event (AE) is any untoward medical occurrence in a 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, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Pre-existing conditions which worsened during this study were reported as AEs. 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.
