Anemia
Conditions
Brief summary
BCD-131 is pegylated darbepoetin beta. BCD-131-2 is International Multicenter Randomized Open-Label Comparative Study (Phase II) of the Efficacy and Safety of BCD-131 and Mircera in Treatment of Anemia in Chronic Kidney Disease Patients on Dialysis.
Detailed description
The hypothesis of the study is that the efficacy of BCD-131 is equivalent to that of Mircera® based on the analysis of the primary endpoint (changes in the Hb level over the period of evaluation as compared to the baseline Hb level ) during the 21-week period of treatment. This study is a study of the maintenance treatment of anemia. The study will include up to 100 dialysis patients with stage 5D chronic kidney disease, established efficacy of dialysis and renal anemia without other causes of anemia, receiving erythropoiesis-stimulating agents (ESA) and reaching target hemoglobin levels.
