An Observational Study of Mircera (Methoxy Polyethylene Glycol-Epoetin Beta) in Chronic Kidney Disease Patients on Dialysis With Renal Anemia

Study Overview
=================
Brief Summary
-----------------
This observational study will evaluate the use in clinical practice and efficacy of Mircera (methoxy polyethylene glycol-epoetin beta) in chronic kidney disease patients on dialysis receiving Mircera for the treatment of chronic renal anemia. Eligible patients will be followed for 24 weeks.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Age of Participants Treated With C.E.R.A | Age was calculated on screening/Baseline visit day by using formula: Age = (Screening visit date - Date of birth)/365.25 | Baseline (Week 0) | 
| Mean Weight of Participants Treated With C.E.R.A | Weight of the participants was measured at the Baseline and summarized with descriptive statistics. | Baseline (Week 0) | 
| Number of Participants With Co-morbidity Treated With C.E.R.A | Co-morbidity is the presence of one or more additional disorders (or diseases) co-occurring with a primary disease or disorder; or the effect of such additional disorders or diseases. Co-morbid participants with renal and urinary disorders, vascular disorders, metabolism and nutrition disorders were reported. | Up to Week 24 | 
| Mean Time Required to Achieve Target Hemoglobin Range | The target range of hemoglobin (Hb) was 10-12 gram/deciliter (g/dL). Time to achieve target range = (Date of Hb evaluation when participant achieved target Hb range at first time - visit date of first dosing) + 1 | Up to Week 24 | 
| Percentage of Participants Achieved Target Range of Hemoglobin | The target range of Hb was 10-12 gram/deciliter (g/dL). Time to achieve target range = (Date of Hb evaluation when participant achieved target Hb range at first time - visit date of first dosing) + 1. The percentage of participants with Hb < 10 g/dL at enrollment, achieving the target range of hemoglobin 10-12 g/dL was reported. | Up to Week 24 | 
| Percentage of Participants Who Had Received Treatment With Other Erythropoiesis-Stimulating Agents Maintaining Hb Level Within 1 Gram/Deciliter of Baseline Value During Study Period in Participants. | Percentage of participants maintaining Hb level within 1 g/dL of baseline value during study period who had received treatment with other Erythropoiesis-Stimulating Agents (ESAs) were reported. | Up to Week 24 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Achieving Hb Target Range (10-12 Hb g/dL) at Least Once During the Study | For correction of anemia, number of participants achieving Hb target range (10-12 g/dL) at least once during the study were reported. | Up to Week 24 | 
| Mean Time Spent by Participants in the Hb Target Range | Maintenance of target Hb was evaluated by assessing the mean time spent by participants in target Hb range. The target Hb range in the study was 10-12 g/dL. | Up to Week 24 | 
| Evaluation of Route of Administration for C.E.R.A | C.E.R.A. was administered by Intravenous (IV) and Subcutaneous (SC) route of administration. The frequency (number of injections) for both of these routes of administration used in the study was reported. | Up to Week 24 | 
| Evaluation of Dose Per Injection of C.E.R.A | The dosing and titration of C.E.R.A treatment were at the discretion of the investigator in accordance with local clinical practice or approved prescribing information. Mean dose per injection of C.E.R.A received by participants was reported. | Up to Week 24 | 
| Number of Participants Received Concomitant Medications | Medications that were used during the study treatment period (from the first dose date of study medication to the end of the study) were included as concomitant medications. The prescribed concomitant medications (in greater than or equal to 10% of participants) in the study were prazosin, torasemide, vitamin and nutritional supplements, omeprazole, amlodipine, calcium supplements, calcitriol, and clonidine. Participants treated with the each of these concomitant medications were reported. | Up to Week 24 |
