Filter by:This is a phase II trial using a non-myeloablative cyclophosphamide/ fludarabine/total body irradiation (TBI) preparative regimen with modifications based on factors including diagnosis, disease status, and prior treatment. Single or double unit selected according to current University of Minnesota umbilical cord blood graft selection algorithm.
Allogeneic hematopoietic cell transplantation(Allo-HSCT) is currently an effective treatment for Acute leukemia (AL). Relapse after transplantation, being a main obstacle for patient survival, is so far treated by second transplantation and donor leukocyte infusion (DLI), which seems to have high risk and low survival. Need for a new medication on relapse is urgent. The immunotherapy using Dendritic cells (DCs) combined with cytokine induced killer (CIK) cells holds promise for the adjuvant treatment of AL to eradicate or control residual disease. This randomized study was conducted to evaluate the feasibility and effective of genetically modified DCs combining to CIK immunotherapy in relapse AL after allo-HSCT.
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.
As one of the nation's largest cooperative cancer treatment groups, the Alliance for Clinical Trials in Oncology (Alliance) is in a unique position to organize a Leukemia Tissue Bank. The member institutions diagnose hundreds of patients with leukemia or myelodysplastic syndrome each year, and uniformly treat these patients with chemotherapy regimens. The Alliance offers centralized data management for the clinical history, the classification of the leukemia and myelodysplastic syndrome, cytogenetics, flow cytometric analysis, treatment and follow-up. The highly skilled health care providers at each member institution are familiar with obtaining informed consent, completing data questionnaires and shipping specimens. There currently exists a central processing facility where samples are prepared for a variety of cellular and molecular studies. Hence, the patient resources, the health care providers, and a processing facility for a Leukemia Tissue Bank are all in place. What is needed, however, and is addressed in the current protocol, is a formal mechanism to procure bone marrow, blood and normal tissue from patients with hematologic malignancies who are to be enrolled on Alliance (Cancer and Leukemia Group B [CALGB]) treatment studies.
Chromosomal analysis or the study of genetic differences in patients previously untreated with AML, ALL, MDS or MM may be helpful in the diagnosis and classification of disease. It may also improve the ability to predict the course of disease and the selection of therapy. Institutions must have either an Alliance-approved cytogeneticist or an agreement from an Alliance-approved main member cytogenetics laboratory to enroll a patient on CALGB 8461. The Alliance Approved Institutional Cytogeneticists list is posted on the Alliance for Clinical Trials in Oncology website.
