Antithymocyte Globulin Compared With Supportive Care in Treating Patients With Myelodysplastic Syndrome
RATIONALE: Immunosuppressive therapy may improve bone marrow abnormalities and may be effective treatment for myelodysplastic syndrome. It is not yet known whether immunosuppressive therapy is more effective than supportive care in treating myelodysplastic syndrome.
PURPOSE: Randomized phase II trial to compare the effectiveness of antithymocyte globulin with that of supportive care in treating patients who have myelodysplastic syndrome.
|Study Design:||Allocation: Randomized
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||An Open Label, Prospective, Stratified, Randomized, Controlled, Multi-Center, Phase IIB Study of the Impact of Thymoglobulin Therapy on Transfusion Needs of Patients With Early Myelodysplastic Syndrome (MDS)|
|Study Start Date:||August 2001|
- Compare the clinical response rate of patients with early myelodysplastic syndrome treated with rabbit anti-thymocyte globulin vs standard supportive care.
- Evaluate the safety of anti-thymocyte globulin in these patients.
- Compare the time to and duration of clinical response, rates of partial response and therapy failure, and rate of disease progression in patients treated with these regimens.
- Compare the ECOG performance score, number of transfusions and/or growth factor use, and maximum time between transfusions in patients treated with these regimens.
- Compare the infection risk, use of medical resources, and quality of clinical response in patients treated with these regimens.
OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to myelodysplastic syndrome (MDS) subtype (refractory anemia (RA) vs RA with excess blasts or hypocellular MDS). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive rabbit anti-thymocyte globulin (ATG) IV over at least 8-12 hours on days 1-4.
- Arm II: Patients receive standard supportive therapy for 6 months. At the end of 6 months, patients may receive ATG as in arm I.
Patients are followed for 6 months.
PROJECTED ACCRUAL: A total of 72 patients (48 in arm I and 24 in arm II) will be accrued within a minimum of 6 months.
