Abstract
BACKGROUND:Continuous erythropoietin receptor activator (CERA; methoxy polyethylene glycol-epoetin beta) is a new erythropoiesis-stimulating agent with a prolonged half-life. The objective of this study was to select a starting dose of CERA for the treatment of anemia in non-small-cell lung cancer (NSCLC) patients. PATIENTS AND METHODS: The study was an open-label randomized phase II trial containing four treatment groups of patients with anemia and stage IIIB or IV NSCLC. The fourth treatment group was a reference group of patients treated with darbepoetin alfa administered at either 6.75 μg/kg s.c. every 3 weeks or 2.25 μg/kg weekly. Due to observed imbalances in death across treatment arms, this study was prematurely terminated. RESULTS: The primary efficacy parameter of the mean hemoglobin (Hb) change from baseline during weeks 5-13 was +0.03 g/dl, +0.50 g/dl, and -0.02 g/dl in the CERA 6.3, 9, and 12 μg/kg dose groups, respectively, and +0.26 g/dl in the darbepoetin alfa dose group (P value not significant for all three study arms). Eight (21%), 12 (32%), 9 (24%), and 4 (10%) patients in the CERA 6.3, 9, and 12 μg/kg and darbepoetin groups, respectively, died. CONCLUSION: In this phase II study in patients with stage IIIB or IV NSCLC receiving chemotherapy, none of the four treatment arms showed an adequate increase in mean Hb level.
