Filter by:RATIONALE: Giving chemotherapy drugs, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells and prepares the patient's bone marrow for the stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing an umbilical cord blood transplant for hematologic cancer.
Primary Objective: A. To determine whether stable allogeneic hematopoietic engraftment can be safely established in patients receiving a non-myeloablative allogeneic SCT from a matched sibling donor, with fludarabine and low-dose TBI, with pre- and post-transplant immunosuppression with tacrolimus and MMF. B. To evaluate the incidence of grade II-IV GVHD associated with this treatment.
This is a Phase I/II multi-center, open label, dose escalation study to identify the maximum tolerated dose (MTD) of liposomal annamycin and to evaluate the safety of liposomal annamycin in patients with refractory or relapsed acute lymphocytic leukemia.
The purpose of this study is to evaluate the side effects of 9-Aminocamptothecin (9-AC) and to determine the best dose which should be used to treat leukemia.
The purpose of this research study is to identify better ways to treat children and young adults with acute lymphocytic leukemia (ALL). At the same time, doctors hope to define methods to identify those patients at higher risk for certain side effects, as well as those who are at higher risk for relapse of their leukemia.
Bone marrow consists of a complex hematopoietic cellular component.When the blood progenitor cells differentiate to mature cells, they will exit unassisted to peripheral blood. On the other hand, the immature cells trapped by marrow-blood barrier. However, malignant transformation of the hematopoietic progenitor cells in AML and CML results in a blockade of their ability to terminally differentiate, causing a rapid accumulation of immature cells.Chemokines have been shown to direct the movement of cells between intravascular and extravascular compartments.The CXC chemokine CXCL12, the ligand of CXCR4, activates distinct signaling pathways that may mediate cell migration.In the preliminary research, we analyze the CXCR4 expression and the chemotactic response of CXCL12 and peripheral plasma in six leukemia cell lines (HL-60, HL-CZ, K562, U937, Raji and Jurkat) and found that three categories among them could be suggested: one is CXCR4 (-) and CXCL12 response (-), such as HL-CZ and K562 cells; the other is CXCR4 (+) and CXCL12 response (-), such as HL-60 and Raji cells; the rest is CXCR4 (+) and CXCL12 response (+), such as Jurkat and U937 cells. These results make us wonder that the leukemic cells could egress to PB from BM is due to destruction of homing process or the activation of mobilization process through CXCR4-CXCL12 axis dysfunction. Therefore,we will focus on evaluating the mechanism of CXCR4-CXCL12 axis dysfunction in the various leukemic cell lines and primary leukemic cells.
ALL patients aged 55 years or older were treated with steroids during one week and Ph+ve cases were then offered a specific therapy including an induction treatment with steroids, cyclophosphamide, daunorubicin and vincristine, followed, irrespective of response to induction chemotherapy, by imatinib, 600 mg daily, combined with intermittent steroids during 2 months. Patients in complete response (CR) were then given 10 blocks of alternating chemotherapy, including 2 additional two-month blocks of imatinib, for a total treatment duration of 2 years. Therapy of occult central nervous system leukemia included 5 intrathecal injections of methotrexate and cranial irradiation. Duration of therapy : 2 years.
Recent studies of conventional chemotherapy for infants with high-risk hematologic malignancies show that the long-term disease-free survival is low. Although blood and marrow stem cell transplantation using an HLA identical sibling has improved the outcome for these children, less than 25% have this donor source available. Another option is haploidentical transplantation using a partially matched family member donor (i.e. parental donor). Although haploidentical transplantation has proven curative for some patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including infection and graft versus host disease (GVHD). Building on prior institutional trials, this study will provide patients a haploidentical graft depleted of T lymphocytes using the investigational device, CliniMACS selection system. One week after the transplant procedure, patients will also receive an infusion of additional donor derived white blood cells called Natural Killer (NK) cells in an effort to decrease risks for rejection of the graft, disease relapse, and regimen related toxicity. The primary objective of the study is to evaluate 1 year survival in infants with high risk hematologic malignancies who receive this study treatment.
The goals and objectives of this project are to evaluate the antileukemic activity of the investigational agent clofarabine in patients with acute myelogenous leukemia (AML), acute lymphocytic leukemia (ALL), and chronic myelogenous leukemia (CML) in accelerated and blastic phases.
This study hopes to show that specially treated umbilical cord cells, called stem cells, can be safely given to a person after they receive chemoradiation therapy or chemotherapy for their illness. During chemoradiation therapy or chemotherapy, a person loses all of the cells that are needed to make the different types of cells in their blood, including their immune system cells. These cells must be replaced in order for the blood and immune systems to work properly. Some people receive bone marrow transplants or other types of stem cell transplants to get the cells they need. CB001 is being developed as an option for people who need bone marrow transplants or other types of transplants to replace those cells. It is also being developed for people who do not have the option of other types of transplants.
