Filter by:Blood and marrow stem cell transplant has improved the outcome for patients with high-risk hematologic malignancies. However, most patients do not have an appropriate HLA (immune type) matched sibling donor available and/or are unable to identify an acceptable unrelated HLA matched donor through the registries in a timely manner. Another option is haploidentical transplant using a partially matched family member donor. Although haploidentical transplant has proven curative in many patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including GVHD and infection due to delayed immune reconstitution. These can, in part, be due to certain white blood cells in the graft called T cells. GVHD happens when the donor T cells recognize the body tissues of the patient (the host) are different and attack these cells. Although too many T cells increase the possibility of GVHD, too few may cause the recipient's immune system to reconstitute slowly or the graft to fail to grow, leaving the patient at high-risk for significant infection. For these reasons, a primary focus for researchers is to engineer the graft to provide a T cell dose that will reduce the risk for GVHD, yet provide a sufficient number of cells to facilitate immune reconstitution and graft integrity. Building on prior institutional trials, this study will provide patients with a haploidentical graft engineered to specific T cell target values using the CliniMACS system. A reduced intensity, preparative regimen will be used in an effort to reduce regimen-related toxicity and mortality. Two groups of patients were enrolled on this study. One group included those with high-risk hematologic malignancies and the second group included participants with refractory hematologic malignancies or undergoing a second transplant. The primary aim of the study was to estimate the relapse rate in the one group of research participants with refractory hematologic malignancies or those undergoing second allogeneic transplant. Both groups will be followed and analyzed separately in regards to the secondary objectives. This study was closed to accrual on April 2006 as it met the specific safety stopping rules regarding occurrence of severe graft vs. host disease. Although this study is no longer open to accrual, the treated participants continue to be followed as directed by the protocol.
This purpose of this study is to assess the toxicity and the rate of complete and overall response using fludarabine, rituximab, and alemtuzumab to treat patients with B-chronic lymphocytic leukemia or small lymphocytic leukemia who have received previous treatment.
The primary objective is to estimate the overall event-free survival of children at least one year of age at diagnosis who are treated with risk-directed therapy and to monitor the molecular remission induction rate.
The purpose of this study is to determine the safety and optimal dosing of L-asparaginase in adult patients with acute lymphoblastic leukemia (ALL) between the ages of 18 and 50 years.
The purpose of this study is to measure the effectiveness of 2 drugs, tacrolimus and sirolimus, in preventing graft versus host disease (GVHD) after treatment with chemotherapy followed by donor cord blood transplantation.
This phase I trial is studying the side effects and best dose of sorafenib in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, or chronic myelogenous leukemia. Sorafenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer
This research study measures the safety and efficacy of the combination of three drugs that are approved, Nipent, Rituxan and Cytoxan in the treatment of Chronic Lymphocytic Leukemia (CLL). These drugs are being given together for investigational purposes as the specific combination of these three drugs has not been approved for treatment of CLL by the FDA.
The purpose of this study is to investigate the efficacy and safety for treating adult ALL patients with the pediatric protocol.
The purpose of this study is to investigate the clinical efficacy of high-dose methotrexate consolidation therapy for adult patients with BCR-ABL-negative ALL.
The purpose of this study is to investigate possible genetic factors that contribute to the development of lymphomas. The databank will be used to determine whether familial lymphomas have unique genetic characteristics different from sporadic lymphomas and to attempt to identify a gene that confers an increased risk of lymphoma.
