Post-Transplant Bendamustine (PT-BEN) for GVHD Prophylaxis
This phase I/II trial studies the side effects and best dose of bendamustine when given with or without cyclophosphamide in preventing graft versus host disease (GVHD) in patients undergoing stem cell transplant. Drugs used in chemotherapy, such as bendamustine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy and total body irradiation before or after a stem cell transplant helps kills cancer cells that are in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. Sometimes, the transplanted cells from a donor can attack the body's normal cells called GVHD. Giving tacrolimus, mycophenolate mofetil, and filgrastim after the transplant may stop this from happening.
• Patient with hematologic malignancies.
• Donor: Matched sibling, matched unrelated, mismatched or haploidentical
• Zubrod performance 0 to 2 or Karnofsky of at least 60.
• Adequate organ function at time of study entry:
‣ Creatinine less than or equal to 1.6 mg/dL and creatinine clearance \>/= 30 ml/min. Creatinine clearance will be calculated using the Cockcroft-Gault equation
⁃ Total bilirubin less than \< 1.5 x UNL
⁃ SGPT \< 2.5 x ULN
⁃ Ejection fraction \>/= 40%
⁃ FEV1, FVC and DLCO \>/= 40%
• Female patients of childbearing potential must agree to use an effective method of birth control while on study and for 6 months after the last dose of bendamustine. Male patients with female partners of childbearing potential must agree to use an effective method of birth control while on study and for 3 months after the last dose of bendamustine.
