Filter by:GVHD prevention using a combination of post-transplantation cyclophosphamide in combination with abatacept, vedolizumab and calcineurin inhibitor in children and young adults with hematoloblastosis after myeloablative conditioning regimen with treosulfan/TBI, cyclophosphamide/etoposide, fludarabine after HSCT from matched unrelated and haploidentical donors
This phase II trial studies how well trametinib works in treating patients with juvenile myelomonocytic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This is a prospective non-therapeutic study, assessing the long-term toxicity of pediatric HCT for hematologic malignancies. This study is a collaboration between the Pediatric Blood and Marrow Transplant Consortium (PBMTC), the Center for International Blood and Marrow Transplant Research (CIBMTR), the National Marrow Transplant Program (NMDP) and the Resource for Clinical Investigation in Blood and Marrow Transplantation (RCI-BMT) of the CIBMTR. The study will enroll pediatric patients who undergo myeloablative HCT for hematologic malignancies at PBMTC sites.
There is no curative therapy once acute leukemia patients relapse after transplant. Patients who develop clinically significant graft versus host disease (GVHD) have a lower rate of relapse than those who do not develop GVHD. We are initiating this study of post-transplant fast withdrawal of immunosuppression and donor lymphocyte infusions, with a goal of achieving full donor chimerism in children with hematologic malignancies. If our hypothesis that full donor chimerism results in leukemia-free survival is correct, using immune modulation to achieve full donor chimerism should decrease relapse rate and thus increase survival. The goal of this Phase II study is to identify if achieving full donor chimerism in whole blood CD3+ and leukemia-specific (CD14/15+, CD19+, CD33+ and CD34+) subset may decrease the risk of relapse of patients undergoing allogeneic transplant for hematologic malignancy.
The aim of the study is to improve the accuracy of diagnosis for children and adolescents with MDS by a standardized review of morphology and standardized cytogenetic and molecular analysis. The primary objectives of the study are: - To evaluate the frequency of the different subtypes of MDS in childhood and adolescence by a standardized diagnostic approach - To evaluate the frequency of cytogenetic and molecular abnormalities: Specifically using array-CGH to evaluate the frequency of subtle chromosomal imbalances, i.e. gains and losses of defined chromosomal regions, and amplifications. Specifically using mFISH to identify unknown chromosomal aberrations, particularly subtle translocations involving new candidate genes, and to better define chromosomal breakpoints. The secondary objectives of the study are: - To assess survival for children and adolescents with MDS and JMML - To evaluate relapse rate, morbidity and mortality in children with MDS and JMML treated by HSCT
This phase II trial is studying the side effects and best dose of alemtuzumab when given together with fludarabine phosphate and total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients who are undergoing a donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, a monoclonal antibody, such as alemtuzumab, and radiation therapy before a donor stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's bone marrow 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 cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.
