Although previous studies have recognized that timely correction of anemia is desirable, no published research quantifies the association between the timeliness of the hemoglobin rise and patients' outcomes. This study evaluates whether anemic patients with cancer who are receiving chemotherapy and who experienced an early response to epoetin alfa (≥ 1 g/dL hemoglobin increase at the end of 4 weeks of treatment) experienced better clinical and drug utilization outcomes compared with patients who did not experience an early response. Three large, open-label, community studies of epoetin alfa for the treatment of chemotherapy-related anemia were retrospectively analyzed to assess the association of early hemoglobin response to subsequent transfusion requirements, subsequent hemoglobin response, quality of life, and epoetin alfa dosage administered over the study. Two epoetin alfa dosing regimens were evaluated: 10,000 units 3 times weekly with potential escalation to 20,000 units, and 40,000 units once weekly with potential escalation to 60,000 units. In all studies, patients who experienced an early hemoglobin response had statistically lower subsequent transfusion requirements, higher rates of subsequent hemoglobin response, shorter time to hemoglobin response, better improvements in quality of life scores, and lower average weekly epoetin alfa dose than patients who did not experience an early hemoglobin response. Similar proportions of patients experienced early response in the 3-times weekly and once-weekly epoetin alfa regimens. This ad hoc analysis found that early hemoglobin response to epoetin alfa therapy was associated with improved clinical benefits and drug utilization. Early hemoglobin response may therefore be considered as a desired goal of epoetin alfa therapies.

These factors together increase the potential for inappropriate overuse of costly drugs with marginal benefits. Oversight of drug use, such as by institutional drug formulary committees, can protect against this practice at the final stage of drug
