数据说明

Conditions: Leukemia, Myelodysplastic Syndromes. OBJECTIVES: Primary * Determine the hematological response rate in patients with myelodysplastic syndromes treated with azacitidine, darbepoetin alfa, and filgrastim (G-CSF). Secondary * Determine the time to leukemia progression, survival, and changes in apoptotic index of bone marrow in patients treated with this regimen. OUTLINE: This is an open-label, nonrandomized study. * Initial therapy (courses 1 and 2): Patients receive azacitidine subcutaneously (SC) or intra-venous (IV) on days 1-5 (week 1) and darbepoetin alfa* SC on day 8 (week 2). Treatment repeats every 28 days for 2 courses. Patients undergo bone marrow aspirate and biopsy to assess response. Patients with a major hematological improvement OR with grade 3-4 hematological toxicities during the first 2 courses of therapy AND/OR ≥ 50% reduction in bone marrow cellularity compared to baseline proceed to optimization therapy A. Patients not meeting any of the above criteria proceed to optimization therapy B. Patients with disease progression are removed from study. * Optimization therapy A (courses 3-8): Patients receive azacitidine SC or IV on days 1-5 (week 1), darbepoetin alfa** SC on day 8 (week 2), and filgrastim (G-CSF) SC 3 times weekly in weeks 2-4. * Optimization therapy B (courses 3-8): Patients receive a higher dose of azacitidine on days 1-5 (week 1), darbepoetin alfa** SC on day 8 (week 2), and G-CSF 3 times weekly in weeks 2-4. In both optimization therapy A and B, treatment repeats every 28 days for 6 courses. Patients with any degree of hematological improvement after initial therapy and optimization therapy proceed to maintenance therapy. * Maintenance therapy (course 9 and all subsequent courses): Patients receive azacitidine on days 1-5 (week 1). Only patients with anemia (hemoglobin < 12 g/dL) and/or neutropenia (absolute neutrophil count < 1,500/mm ³) at the start of any given course during maintenance therapy receive darbepoetin alfa** SC beginning on day 8 (week 2) and continuing on
