简要总结
This randomized phase III trial is studying tacrolimus, methotrexate, and sirolimus to see how well they work compared to tacrolimus and methotrexate in preventing graft-versus-host disease in young patients who are undergoing donor stem cell transplant for intermediate-risk or high-risk acute lymphoblastic leukemia in second complete remission and high risk acute lymphoblastic leukemia in first remission. Giving chemotherapy, such as thiotepa and cyclophosphamide, and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus, methotrexate, and sirolimus after the transplant may stop this from happening. It is not yet known whether tacrolimus and methotrexate are more effective with or without sirolimus in preventing graft-versus-host disease.
详细描述
PRIMARY OBJECTIVES:
I. Compare the post-transplant 2-year event-free survival of pediatric patients with intermediate-risk or high-risk acute lymphoblastic leukemia (ALL) in second complete remission or high risk ALL in first remission undergoing allogeneic hematopoietic stem cell transplantation treated with graft-versus-host disease (GVHD) prophylaxis comprising tacrolimus and methotrexate with or without sirolimus.
SECONDARY OBJECTIVES:
I. Compare rates of relapses, transplant-related mortality, and acute and chronic GVHD in these patients.
II. Evaluate the relative contribution of resistance by ALL blasts to cytolytic therapy (e.g., chemotherapy/irradiation) as a cause of relapse post-transplantation by correlating ALL in vivo blast resistance with in vivo sirolimus, inhibition levels of the mTOR pathway in patients treated with sirolimus, and altered resistance pathways in ALL blasts measured by microarray analysis.
