Brief Summary

The purpose of this study is to see if a condensed version of the chemotherapy regimen busulfan, melphalan, fludarabine (bu/mel/flu) and the drug antithymocyte globulin (ATG-also referred to as rATG or thymoglobulin) can have the same or fewer number of severe side effects in people with various blood cancers 30 days after they receive an allogeneic hematopoietic cell transplantation.

Study Groups

patients hematologic malignancies other than multiple myeloma

A. Busulfan 3.2 mg/kg/day, with dose adjustments made according to pharmacokinetic (PK) levels. B. Melphalan (70mg/m2/day) administered on days -6 and -5. C. Fludarabine (25mg/m2/ day) administered on days -6, -5, -4, -3, and -2. All patients receiving matched related or unrelated donor allografts receive anti-thymocyte globulin (ATG) 2.5 mg/kg/day on days -3 and -2 to deplete chemotherapy resistant host T-cells that could hinder engraftment, and it may provide additional GVHD prophylaxis.

Group Type: EXPERIMENTAL

Intervention Type: DRUG

Busulfan 3.2 mg/kg/day, with dose adjustments made according to pharmacokinetic (PK) levels.

Antithymocyte globulin (ATG)

Intervention Type: DRUG

Intervention Type: PROCEDURE
