About

This randomized clinical trial studies standard GVHD prophylaxis with tacrolimus and methotrexate compared to tacrolimus, mycophenolate mofetil and a reduced-dose methotrexate in patients with hematologic malignancies undergoing allogeneic hematopoietic cell transplant. Both mycophenolate mofetil and reduced-dose methotrexate, in combination with a calcineurin inhibitor, have been shown to be safe and effective in GVHD prevention with less toxicity than standard dose methotrexate. It is not yet known, however, whether this combination of mycophenolate mofetil and reduced-dose methotrexate with tacrolimus is more effective than tacrolimus and standard dose methotrexate in preventing GVHD.

Full description

Study Design This is a prospective randomized trial to determine the effectiveness of different doses of GVHD prophylaxis on mucositis, engraftment and aGVHD. Study consists of two study groups of 50 subjects each.

Group A will receive Tac and MTX (15 mg/m2 day +1, 10 mg/m2 day +3, +6, +11). Group B will receive Tac, Mini-dose MTX (5 mg/m2 on day +1, +3, +6) and MMF.

101 participants in 2 patient groups

Group A (tacrolimus, methotrexate)
Active Comparator group
Description:
Participants receive tacrolimus IV over 24 hours beginning on day -1 (or tacrolimus orally beginning on day -3) and then PO BID after engraftment with a taper from day 100 to day 180 (in the absence of GVHD). Patients also receive methotrexate IV on days 1, 3, 6, and 11.
Treatment:
Drug: methotrexate
Drug: tacrolimus
Group B (tacrolimus, methotrexate, mycophenolate mofetil)
Experimental group
Description:
Patients receive tacrolimus as in group A and methotrexate (low dose) IV on days 1, 3, and 6. Patients also receive oral mycophenolate mofetil BID beginning on day 1, with a taper from day 45 to day 100 (in the absence of GVHD).
Treatment:
Drug: Methotrexate (low dose)
Drug: Mycophenolate mofetil
Drug: tacrolimus
