Biosimilar erythropoietin in anemia treatment (BEAT)-Efficacy and safety of a 1:1 dose conversion from EPREX® to EPIAO® in patients with end-stage renal disease on hemodialysis: A prospective, randomized, double blind, parallel group study.
Medicine (Baltimore) 2022 November 26
BACKGROUND: EPREX®/ERYPO®/PROCRIT® (epoetin alfa, Janssen-Cilag GmbH) was the first available recombinant human erythropoietin (rHuEPO) and was universally reference product as per the recommendation provided by European Medicines Agency. EPIAO® is a biosimilar formulation of EPREX®, and making it a 1:1 dose conversion from EPREX® according to recommendation of European Medicines Agency. This study evaluated the clinical efficacy and safety of EPIAO® in subjects with end-stage renal disease receiving hemodialysis after intravenous administration.
METHODS: This study was a multicenter, prospective, randomized, double-blind, parallel-group, 2-cohort, maintenance phase, therapeutic equivalence study to evaluate a 1:1 dose conversion from EPREX® to EPIAO® in terms of clinical efficacy and safety that was conducted at 20 sites in 2 countries in patients with end-stage renal disease on hemodialysis. Eligible subjects were treated with EPREX® (reference product of epoetin) for a period of at least 3 months before the treatment period, and then were randomly assigned to the group of EPREX® or EPIAO®. Primary endpoints were mean absolute change in hemoglobin level and mean absolute change in weekly epoetin dosage from baseline to 6 months after treatment with EPIAO®/EPREX® in parallel groups.
RESULTS: A total of 200 people received the random intervention and were included in the safety set. After 6, 9, and 12 months of treatment with EPIAO® or EPREX®, there were no significant differences in the hemoglobin levels of the 2 groups compared with baseline. The 95% confidence interval for the treatment difference was within the predetermined acceptable range: ±0.5 g/dL. There were no significant differences in the epoetin dosage of the 2 groups compared with the baseline. The 95% confidence interval for the treatment difference was within the predetermined acceptable range: ± 45 IU/kg. There were no significant differences in the incidence of adverse events between the EPIAO® and EPREX® groups. Most adverse events were mild to moderate and were reverted/resolved.
CONCLUSION: EPIAO® demonstrated promising effectiveness and manageable safety in patients with end-stage renal disease on hemodialysis.
