Abstract

The recombinant human erythropoietins and allied proteins (epoetin alfa, attempted copies and biosimilar variants of epoetin alfa, epoetin beta, epoetin delta, epoetin zeta, epoetin theta, epoetin omega, darbepoetin alfa, and methoxy-polyethylene glycol-epoetin beta) are among the most successful and earliest examples of biotechnologically manufactured products to be used in clinical medicine. This article charts a brief history of their use in clinical medicine, mainly dealing with chronic kidney disease, paying special attention to how these agents were introduced into clinical medicine and what has happened subsequently; in 2009, there were several developments that could be regarded as a "perfect storm" in terms of the long-term use of these compounds in chronic kidney disease and oncology and, likely, elsewhere. We are now very much at a "crossroads," where mature reflection is required, because with the latest trials and meta-analyses, these therapies seem not only expensive but also very much a clinical tradeoff (increased risk of adverse effects versus a small gain in fatigue scores). How we arrived at this crossroads is a useful illustration of how easy it is, without properly designed randomized, controlled trials, to assume that clinical benefit must follow therapeutic interventions.
