    Abstract:
    OBJECTIVE: To determine a recommended dose of once-weekly epoetin-beta administration for anemic cancer patients receiving myelosuppressive chemotherapy, we conducted a multicenter, randomized, double-blind trial. METHODS: A total of 86 patients with malignant lymphoma or lung cancer who received chemotherapy containing platinum, taxanes or anthracyclines were enrolled in the study. Patients were randomly assigned into groups that received three dose levels of epoetin-beta (9000, 18,000 or 36,000 IU) administered subcutaneously once a week for 12 weeks. The primary endpoint was change in hemoglobin, while the secondary endpoints were quality of life (QOL) assessed by Functional Assessment of Cancer Therapy-Anemia (FACT-An) questionnaire and transfusion requirements. RESULTS: Among the 69 patients (per protocol set population) assessable for efficacy, hemoglobin level change in the 36,000 IU group was significantly greater than that in the 9000 IU group (1.75 +/- 2.15 versus 0.04 +/- 1.98 g/dl; P = 0.009), and a significant dose-response relationship was observed for the change in hemoglobin level (P = 0.003). Although changes in FACT-An Total Fatigue subscale (Fatigue subscale) scores were similar for the three dosage groups, there was a statistically significant correlation (r = 0.435, P < 0.001) between the change in hemoglobin levels and the change in Fatigue subscale scores. The proportion of transfused patients was significantly smaller in the 36 000 IU group compared with that in the 9000 IU group (P = 0.022, not adjusted for pre-study transfusions). The incidence of adverse events was similar in the three dosage groups. CONCLUSIONS: Once-weekly epoetin-beta 36,000 IU for 12 weeks was well tolerated and significantly increased hemoglobin levels in anemic cancer patients receiving chemotherapy.
