Long-Term Safety and Efficacy of JR-131, a Biosimilar of Darbepoetin Alfa, in Japanese Patients With Renal Anemia Undergoing Hemodialysis: Phase 3 Prospective Study.

ABSTRACT: The objective of this study was to evaluate the safety and efficacy of JR-131, a biosimilar of darbepoetin alfa, for long-term treatment of renal anemia patients undergoing hemodialysis. In this multicenter, single-arm, phase 3 study, 159 patients with renal anemia who had been receiving darbepoetin alfa or recombinant human erythropoietins were treated with intravenous JR-131 for 52 weeks. In patients receiving darbepoetin alfa, JR-131 was administered at the same dose, while in patients receiving recombinant human erythropoietin the dose was determined based on the 1:200 conversion ratio following the Japanese darbepoetin alfa package insert. No notable adverse drug reactions were reported, and no anti-JR-131 antibodies were detected. The hemoglobin levels were maintained in the range of
