What was measured

The number of days to reach a platelet count of greater than or equal to 20,000/ul for three consecutive laboratory values obtained on different days, independent of platelet transfusions the prior 7 days. The day of engraftment will be the first day of the three consecutive laboratory values. For cases of delayed engraftment beyond 28 days, results will be recorded once the participant engrafts.

Analysis population: participants that were able to engraft platelets

Groups in this outcome

Group A (Tacrolimus, Methotrexate)

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. tacrolimus: Tacrolimus 0.03 mg/kg/day beginning day -1 or tacrolimus 0.03mg/kg/dose BID orally beginning on day -3. If Tac is administered intravenously, it will be given over 24 hours and will be converted to oral administration 2 times a day when the patient has engrafted and/or can tolerate oral medication. Levels of Tac will be obtained to maintain a recommended target serum level of 5-12 ng/mL methotrexate: MTX 15mg/m2 IV on day +1, followed by 10mg/m2 on day +3, +6, +11. If patient \< 10 kg then MTX will be given at 0.5 mg/kg IV on day +1. Then MTX will be given at 0.33 mg/kg on days +3, +6 and +11.

Group B (Tacrolimus, Methotrexate, Mycophenolate Mofetil)

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). tacrolimus: Tacrolimus 0.03 mg/kg/day beginning day -1 or tacrolimus 0.03mg/kg/dose BID orally beginning on day -3. If Tac is administered intravenously, it will be given over 24 hours and will be converted to oral administration 2 times a day when the patient has engrafted and/or can tolerate oral medication. Levels of Tac will be obtained to maintain a recommended target serum level of 5-12 ng/mL Mycophenolate mofetil: Patients will receive Mycophenolate beginning on day +1. Patients \>40 kg will receive Mycophenolate 1000 mg twice a day. Mycophenolate should be given orally twice a day. IV formulation may be used if the patient cannot tolerate oral route. Patients \< 40 kg will receive MMF 45 mg/kg/day (15 mg/kg three times a day). MMF may be given orally or intravenously as per institutional protocol Methotrexate (low dose): MTX 5mg/m2 IV on day +1, +3, +6. If patient\<10 kg MTX will be given at 0.17 mg/kg on day +1, +3, and +6.
