- Registration Number
- NCT00003138
- Lead Sponsor
- Eastern Cooperative Oncology Group
- Brief Summary
RATIONALE: Erythropoietin and colony-stimulating factors such as filgrastim stimulate the production of blood cells. It is not yet known whether erythropoietin with or without filgrastim is more effective than standard blood transfusions in reducing the need for transfusions in patients who have anemia associated with myelodysplastic syndrome.
PURPOSE: Randomized phase III trial to compare the effectiveness of erythropoietin with or without filgrastim with that of standard blood transfusions in reducing the need for transfusions in patients who have anemia associated with myelodysplastic syndrome.
- Detailed Description
OBJECTIVES:
* Compare the benefit of erythropoietin vs standard transfusion support in reducing transfusion requirements in patients with myelodysplastic syndromes.
* Compare the clinical response, disease progression, and survival in patients treated with these regimens.
* Compare the toxicity of these regimens in these patients.
* Evaluate whether adding filgrastim (G-CSF) or increasing the erythropoietin dose will reduce the transfusion requirement in patients who do not respond to erythropoietin alone.
* To compare the benefit of erythropoietin versus supportive care alone on quality of life (QOL) in persons with myelodysplastic syndromes.
OUTLINE: This is a randomized, controlled, multicenter, cross-over study. Patients are stratified according to morphologic subtype (refractory anemia \[RA\] vs RA with ringed sideroblasts vs RA with excess blasts), transfusion requirement (yes vs no), prior erythropoietin treatment (yes vs no), and erythropoietin level (at least 200 mU/mL vs less than 200 mU/mL). Patients are randomized to one of two treatment arms.
* Arm I (standard transfusion support): Patients receive red cell and platelet transfusions for symptoms or to maintain hematocrit level of 25% or above. Patients undergo bone marrow aspirate and biopsy at 4 months and then every year until development of acute leukemia or completion of study. Patients with progressive disease may cross over to arm II after at least 4 months on study and up to 1 year from the time of randomization. Patients who cross over receive erythropoietin alone.
* Arm II (Erythropoietin): Patients receive erythropoietin subcutaneously (SC) or intravenously (IV) daily. Patients undergo bone marrow aspirate and biopsy as in arm I. Treatment continues daily for a maximum of 1 year.
Patients with stable or progressive disease at day 120 receive filgrastim (G-CSF) SC daily or 3 days a week and erythropoietin SC daily for up to 6 months. Patients with no response to G-CSF and lower-dose erythropoietin may proceed to a higher dose of erythropoietin.
Quality of life is assessed at baseline, every 4 months during study, and at study completion.
Patients are followed every 4 months for 2 years, every 6 months for 3 years, and then annually for 5 years.
ACTUAL ACCRUAL: A total of 118 patients were accrued for this study.

Group Intervention Description Erythropoietin Filgrastim Erythropoietin was administered at 150 units/kg subcutaneously every day. If patients stopped responding, they were subsequently treated with Erythropoietin (150 units/kg) and filgrastim and then Erythropoietin (300 units/kg) and filgrastim. Supportive Care Transfusion Patients received red cell and platelet transfusions for symptoms or to maintain hematocrit at or above 25% by volume. Patients who required transfusion support for symptomatic anemia prior to entering the study and who developed an increase in their transfusion requirement of \>= 50% shall cross over to the Erythropoietin treatment arm, after at least four months on the supportive therapy arm. Erythropoietin Erythropoietin Erythropoietin was administered at 150 units/kg subcutaneously every day. If patients stopped responding, they were subsequently treated with Erythropoietin (150 units/kg) and filgrastim and then Erythropoietin (300 units/kg) and filgrastim.
- Primary Outcome Measures
Name Time Method Proportion of Patients Free of Transfusion at 4 Months Assessed at 4 months Whether a patient required transfusion or not at 4 months was recorded.
- Secondary Outcome Measures
Name Time Method Quality of Life- Total Functional Assessment of Cancer Therapy - General (FACT-G) Score at 4 Months Assessed at 4 months The FACT-G scale has 4 dimensions, including physical well-being, social/family well-being, emotional well-being, and functional well-being. The score for each subscale was added together to obtain the total FACT-G score that was evaluated on this study. The total FACT-G score ranges from 0 to 108 with higher scores reflecting better quality of life. It was administered at the time of study entry, every 4 months for the first year, and at the time patient went off treatment. Due to limited data after 4 months on treatment, the analysis was restricted to the four-month time point.
Overall Survival Assessed every 3 months for 2 years, every 6 months for 3 subsequent years, and annually thereafter Time from randomization to death from any cause. Patients alive at the time of analysis were censored at the date of last contact.
