Patients with cancer or chronic kidney disease (17 studies).
Erythropoiesis-stimulating agents (ESAs) including biosimilars.
Addition of iron to an ESA, placebo or best standard therapy.
A growing body of evidence suggested that adding iron to treatment with an ESA may improve hematopoietic response and reduce the likelihood of red blood cell transfusion. The biosimilar literature review suggested that biosimilars of epoetin alfa have similar efficacy and safety to reference products, although evidence in cancer remained limited.
