The U.S. Food and Drug Administration recently approved Pfizer’s biosimilar anemia drug, Retacrit (epoetin alfa-epbx). After two previous approval attempts, Retacrit was approved as a biosimilar to Epogen (Amgen) and Procrit (epoetin alfa, Johnson & Johnson).
Nephrologists as a group appear to be receptive to biosimilars for their patients. Spherix Global Insights reported their approval in a March 2018 survey of 202 nephrologists, especially if Retacrit use should become required by dialysis organizations. Only 22% of nephrologists surveyed agreed with the statement “I would not be pleased if my dialysis center switched to a biosimilar ESA.”
