An Observational Study of Mircera (Methoxy Polyethylene Glycol-epoetin Beta) in Patients With Renal Anemia

Mean hemoglobin was calculated from measurements taken during the Evaluation Period (Month 0 to Month 12). The target hemoglobin range was 10 to 13 gram/deciliter (g/dL). Percentage of participants with at least one hemoglobin value less than (<) 10 g/dL or greater than (>) 13 g/dL during the evaluation period by predialysis/hemodialysis is presented.

The percentage of participants with hemoglobin (Hb) values within the pre-defined ranges (10-12 g/dL, 11-12 g/dL, and 11-13 g/dL) during evaluation period (Month 0 to Month 12) by dose modification (yes or no), age (<65 years, greater than or equal to [>=] 65 years) and center size (>100 participants, less than or equal to [<=] 100 participants) is presented.

The percentage of participants with hemoglobin values within the pre-defined ranges (10-12 g/dL, 11-12 g/dL, and 11-13 g/dL) during Month 6 to Month 12 by dose modification (yes or no), age (<65 years, >=65 years) and center size (>100 participants, <=100 participants) is presented.

For characterization of intra-individual fluctuations, the maximum absolute differences were derived from study period specific individual mean values. Maximum intra-individual fluctuation of hemoglobin values by predialysis/hemodialysis, age (<65 years, >=65 years), and center size (>100 participants, <=100 participants) is presented. Data for this outcome measure was reported for overall participants.

Serum ferritin levels were measured as nanogram/milliliter (ng/mL). Data for this outcome measure was reported for overall participants.

Serum iron levels were measured as microgram/deciliter (mcg/dL). Data for this outcome measure was reported for overall participants.

Transferrin levels were measured as milligram/deciliter (mg/dL). Data for this outcome measure was reported for overall participants.

Transferrin saturation (TSAT) measured as a percentage, is a medical laboratory test. It is the ratio of serum iron and total iron-binding capacity, multiplied by 100. Data for this outcome measure was reported for overall participants.

The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement. Data for this outcome measure was reported for overall participants.

Physicians were asked to rate their satisfaction with the methoxy polyethyleneglycol-epoetin beta treatment at final visit. Physicians' responses were "very satisfied", "satisfied", "undecided", or "not satisfied". One physician could analyze multiple participants but for the purpose of analysis each physician was counted as one for each analyzed participants; hence, the number of physicians (as per this assessment) was equal to the number of participants analyzed. Data for this outcome measure was reported for overall participants.

At final visit, physicians were asked to answer ("yes" or "no") the question, whether they would continue treatment with methoxy polyethyleneglycol-epoetin beta treatment after study completion. Data for this outcome measure was reported for overall participants.

At final visit, physicians were asked to state the reasons in case of discontinuation of treatment with methoxy polyethyleneglycol-epoetin beta. The same participant could have discontinued treatment due to multiple reasons. Data for this outcome measure was reported for overall participants.

Number of participants who switched to other ESA therapies including Aranesp, Biopoin, Biosimilar, Erypo, and NeoRecormon is presented. Data for this outcome measure was reported for overall participants.

Participants were asked to rate their satisfaction with methoxy polyethyleneglycol-epoetin beta treatment at final visit. Participants' responses were "very satisfied", "satisfied", "undecided", or "not satisfied". Data for this outcome measure was reported for overall participants.

Average methoxy polyethylene glycol-epoetin beta dose per application is presented by study month. Mean values were taken when more than 1 application was documented for a participant during the time period considered. Data for this outcome measure was reported for overall participants.
