European Union Registry in Paediatric Chronic Kidney Disease Patients Looking at Safety and Usage Patterns of Darbepoetin Alfa

Study Overview
=================
Brief Summary
-----------------
This European study observes paediatric patients with Chronic Kidney Disease using Darbepoetin Alfa to assess the drug's long term safety and profile the patterns of its use within this population.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Serious Adverse Drug Reactions (SADR), Serious Adverse Events (SAEs) or Events of Medical Interest (EMIs) | An ADR was defined as an undesirable medical occurrence or worsening of a pre-existing medical condition that the investigator considered associated with the use of darbepoetin alfa. An AE is any untoward medical occurrence or worsening of a pre-existing condition whether or not considered to have a causal relationship with darbepoetin alfa. An SADR or SAE is any ADR or AE that is either: • Fatal • Life threatening • Requires or prolongs in-patient hospitalization • A persistent or significant disability/incapacity, or • A congenital anomaly/birth defect. An EMI is defined as one of the following pre-specified AEs: Thromboembolic Events (eg, venous thrombosis, embolism, vascular occlusion) • Seizures • Severe hypertension (Investigator discretion accompanied by recorded blood pressure) • Cardiovascular events (eg, cardiac arrhythmia, myocardial ischaemia/infarction, heart failure) • Pure red cell aplasia (PRCA) • Hypersensitivity reactions (eg, rash, urticaria, anaphylaxis). | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hemoglobin Concentration by Three Monthly Intervals |  | Baseline, Months 3, 6, 9, 12, 15, 18, 21, and 24 | 
| Weight Adjusted Darbepoetin Alfa Monthly Dose by Monthly Intervals | Baseline dose = the daily dose equivalent x 30, where the daily dose equivalent = the last available dose prior to or at Day 1 / reported intended frequency. | Baseline and Months 1 to 24 | 
| Parathyroid Hormone Level by Three Monthly Intervals |  | Baseline, Months 3, 6, 9, 12, 15, 18, 21, and 24 | 
| Number of Participants With Non-serious Adverse Drug Reactions (ADRs) | An ADR was defined as an undesirable medical occurrence or worsening of a pre-existing medical condition that the investigator considered associated with the use of darbepoetin alfa. A non-serious ADR was one in which none of the following applied: Fatal Life threatening Required or prolonged in-patient hospitalization A persistent or significant disability/incapacity, or A congenital anomaly/birth defect. | 2 years |
