- Brief Summary
This phase II trial tests how well ruxolitinib with tacrolimus and methotrexate work to prevent the development of graft versus host disease in pediatric and young adult patients undergoing allogeneic hematopoietic cell transplant for acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome. Ruxolitinib is a type of medication called a kinase inhibitor. It works by blocking the signals of cells that cause inflammation and cell proliferation, which may help prevent graft versus host disease (GVHD). Tacrolimus is a drug used to help reduce the risk of rejection by the body of organ and bone marrow transplants by suppressing the immune system. Methotrexate stops cells from making DNA, may kill cancer cells, and also suppress the immune system, which may reduce the risk of GVHD. Giving ruxolitinib with tacrolimus and methotrexate may prevent GVHD in pediatric and young adults undergoing allogeneic hematopoietic cell transplants.
- Detailed Description
PRIMARY OBJECTIVES:
I. Determine if the addition of ruxolitinib phosphate (ruxolitinib) to tacrolimus and methotrexate as graft-versus-host disease (GVHD) prophylaxis, is safe in pediatric and young adult patients with hematologic malignancies who are eligible to undergo allogeneic hematopoietic cell transplantation (HCT) from a matched donor. (Safety lead-in segment) II. Following a patient safety lead-in, evaluate the efficacy of ruxolitinib, when given as part of reduced intensity HCT from a matched related/unrelated donor, as assessed by 1 year graft-versus-host disease-free and relapse-free (GRFS) rates in pediatric and young adult patients. (Phase II segment)
SECONDARY OBJECTIVES:
I. Estimate the cumulative incidence of acute GVHD (aGVHD) and non-relapse mortality (NRM) at 100-days after transplant.
II. Estimate the cumulative incidence of chronic GVHD (cGVHD) at 1- and 2-years after transplant.
III. Estimate the probabilities of overall and progression-free survival (OS/PFS) at 1- and 2-years after transplant.
IV. Estimate the relapse/progression rate. V. Estimate rate of infection and development of second malignancies including lymphoproliferative disorders at 1- and 2-years post-transplant.
VI. Further evaluate the safety of this regimen by assessing:
VIa. Adverse event type, frequency, severity, attribution, time-course, and duration; VIb. Complications including: infection, and delayed engraftment.
EXPLORATORY OBJECTIVES:
I. Characterize and evaluate hematologic recovery, donor cell engraftment and immune reconstitution by cell count and flow cytometry of lymphocyte subsets.
II. Characterize changes in aGVHD biomarkers (Reg-3alpha, sTNF RI, IL2Ralpha), JAK-regulated pro-inflammatory cytokines (i.e. IL-6, TNFalpha, C-reactive protein \[CRP\], beta2Microglubuolin) and STAT3 phosphorylation (downstream of JAK signaling) over time and by aGVHD status/grade.
III. Evaluate the pharmacokinetics of ruxolitinib in pediatric and young adult patients.
OUTLINE:
Patients receive ruxolitinib orally (PO) twice daily (BID) from day -1 to day +100, tacrolimus intravenously (IV) on day -1, and methotrexate IV on days +1, +3, +6, and +11, and undergo HCT on day 0. Patients also undergo chest computed tomography (CT) and echocardiography (ECHO)/multigated acquisition scan (MUGA) at screening and undergo collection of blood samples throughout the trial.
After completion of study treatment, patients are followed up at 30 days after the last dose of ruxolitinib and at 1 and 2 years post transplant.
