Antithymocyte Globulin and Cyclosporine Compared With Standard Therapy in Treating Patients With Myelodysplastic Syndrome

2014-08-27 03:58:20 | BioPortfolio


RATIONALE: Antithymocyte globulin and cyclosporine may improve blood counts in patients with myelodysplastic syndrome. It is not yet known whether antithymocyte globulin and cyclosporine are more effective than standard therapy for myelodysplastic syndrome.

PURPOSE: This randomized phase III trial is studying antithymocyte globulin and cyclosporine to see how well they work compared to standard therapy in treating patients with myelodysplastic syndrome.



- Compare the efficacy and toxicity of antithymocyte globulin and cyclosporine versus best supportive care in patients with transfusion dependent low or intermediate risk myelodysplastic syndrome.

- Determine whether immunosuppression improves hematopoiesis and reduces transfusion requirements of these patients.

- Determine whether immunosuppression accelerates leukemic transformation and influences survival of these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified by center and risk group.

Patients are randomized to 1 of 2 treatment arms:

- Arm I: Patients receive antithymocyte globulin IV over 3 hours on days 1-5 and oral cyclosporine twice daily on days 1-180.

- Arm II: Patients receive standard supportive care without antithymocyte globulin and cyclosporine.

Patients are followed at 1, 3, and 6 months, then every 6 months for 1.5 years, and then annually for 3 years.

PROJECTED ACCRUAL: A total of 84 patients (42 per arm) will be accrued for this study.

Medical and Biotech [MESH] Definitions

Clonal myeloid disorders that possess both dysplastic and proliferative features but are not properly classified as either MYELODYSPLASTIC SYNDROMES or MYELOPROLIFERATIVE DISORDERS.

These growth factors comprise a family of hematopoietic regulators with biological specificities defined by their ability to support proliferation and differentiation of blood cells of different lineages. ERYTHROPOIETIN and the COLONY-STIMULATING FACTORS belong to this family. Some of these factors have been studied and used in the treatment of chemotherapy-induced neutropenia, myelodysplastic syndromes, and bone marrow failure syndromes.

Clonal hematopoietic stem cell disorders characterized by dysplasia in one or more hematopoietic cell lineages. They predominantly affect patients over 60, are considered preleukemic conditions, and have high probability of transformation into ACUTE MYELOID LEUKEMIA.

Neoplasms located in the blood and blood-forming tissue (the bone marrow and lymphatic tissue). The commonest forms are the various types of LEUKEMIA, of LYMPHOMA, and of the progressive, life-threatening forms of the MYELODYSPLASTIC SYNDROMES.

Immunizing agent containing IMMUNOGLOBULIN G anti-Rho(D) used for preventing Rh immunization in Rh-negative individuals exposed to Rh-positive red blood cells.
