Brief summary

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.

Detailed 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.

Interventions

DRUGtacrolimus

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

DRUGmethotrexate

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.

DRUGMycophenolate 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

DRUGMethotrexate (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.

MeasureTime frameDescription
Cumulative Incidence of Participants With Acute GVHDDay 7- Day 100Acute GVHD by grade will be estimated using cumulative incidence methods and compared using the Gray test. A lower clinical grade and/or stage of GVHD corresponds to a better participant outcome and a higher grade corresponds to a worse participant outcome. Grading is as follows: Grade 0: No stage 1-4 of any organ Grade 1: Stage 1-2 skin without liver, upper GI, or lower GI involvement. Grade 2: Stage 3 rash and/or stage 1 liver and/or stage 1 upper GI and/or stage 1 lower GI. Grade 3: Stage 2-3 liver and/or stage 2-3 lower GI, with stage 0-3 skin and/or stage 0-1 upper GI. Grade 4: Stage 4 skin, liver, or lower GI involvement, with stage 0-1 upper GI. A greater stage of GVHD involves worsening end-organ involvement and worse participant outcomes based on the skin, liver, lower GI, and upper GI.
Percentage of Severe (Grade 3-4) Mucositis Graded According to the World Health Organization (WHO) Grading ScaleUp to day 28Participants (percentage of) will be graded three times per week through day 28 of the study. Incidence will be compared through Wilcoxon rank sum tests. The WHO grading scale for mucositis is scaled depending on the severity of mucositis symptoms, with a lower stage associated with a better outcome and greater stages associated with worse outcomes. The staging is as follows: Stage 0: None Stage 1 (mild): Oral soreness, erythema Stage 2 (moderate): Oral erythema, ulcers, solid diet tolerated Stage 3 (severe): Oral ulcers, liquid diet only Stage 4 (life-threatening): Oral alimentation impossible
Time to Neutrophil EngraftmentUp to 28 daysThe number of days to reach a neutrophil count of greater than or equal to 500/ul for three consecutive laboratory values obtained on different days. The day of engraftment will be the first day of the three consecutive laboratory values.
Time to Platelet EngraftmentThe date the participant engrafts, up to 28 daysThe 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.

Cumulative Incidence of Participants With Acute GVHD

Acute GVHD by grade will be estimated using cumulative incidence methods and compared using the Gray test. A lower clinical grade and/or stage of GVHD corresponds to a better participant outcome and a higher grade corresponds to a worse participant outcome. Grading is as follows: Grade 0: No stage 1-4 of any organ Grade 1: Stage 1-2 skin without liver, upper GI, or lower GI involvement. Grade 2: Stage 3 rash and/or stage 1 liver and/or stage 1 upper GI and/or stage 1 lower GI. Grade 3: Stage 2-3 liver and/or stage 2-3 lower GI, with stage 0-3 skin and/or stage 0-1 upper GI. Grade 4: Stage 4 skin, liver, or lower GI involvement, with stage 0-1 upper GI. A greater stage of GVHD involves worsening end-organ involvement and worse participant outcomes based on the skin, liver, lower GI, and upper GI.

Chimerism Results

Donor chimerism will be assessed by analysis of single-tandem repeats on whole marrow and in lymphocyte enriched or sorted CD3+ T cells and CD33+ granulocytes. Blood will be obtained for donor chimerism Bone Marrow Engraftment analysis at approximately 1, 2, 3, 6, 9 and 12 months or as clinically indicated.
