Filter by:This phase I trial is studying the side effects and best dose of dasatinib in treating young patients with recurrent or refractory solid tumors or Philadelphia chromosome-positive acute lymphoblastic leukemia or chronic myelogenous leukemia that did not respond to imatinib mesylate. Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth
Bexarotene may be useful in the treatment of Acute Myeloid Leukemia (AML). This is the first study on the use of bexarotene to treat patients with AML. The main purpose of this study is to establish the proper dose of bexarotene when used to treat AML. The side effect profile of bexarotene in patients with AML will also be explored.
Clofarabine (injection) is approved by the Food and Drug Administration (FDA) for the treatment of pediatric patients 1 to 21 years old with relapsed or refractory acute lymphoblastic leukemia (ALL) who have had at least 2 prior treatment regimens. This use is based on the induction of complete responses. Randomized trials demonstrating increased survival or other clinical benefit have not been conducted. The purpose of the phase 1 portion of this study was to determine if clofarabine added to a combination of etoposide and cyclophosphamide is safe in children with relapsed or refractory acute lymphoblastic leukemia (ALL) or acute myelogenous leukemia (AML). The purpose of the phase 2 portion of the study was to measure the effectiveness of the combination therapy in children with ALL.
This randomized phase II trial studies azacitidine with or without entinostat to see how well they work compared to azacitidine alone in treating patients with myelodysplastic syndromes, chronic myelomonocytic leukemia, or acute myeloid leukemia. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Entinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine together with entinostat may work better in treating patients with myelodysplastic syndromes, chronic myelomonocytic leukemia, or acute myeloid leukemia.
This phase II trial is studying how well etanercept works in treating young patients with idiopathic pneumonia syndrome after undergoing a donor stem cell transplant. Etanercept may be effective in treating patients with idiopathic pneumonia syndrome after undergoing a donor stem cell transplant.
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.
T-cell and B-cell depletion in allogeneic peripheral blood stem cell transplantation by using immunomagnetic negative and positive selection procedures Background: Removal of T-cells from the donor graft (T-cell depletion) offers the possibility for prevention of GVHD and subsequently less transplant related morbidity and mortality after allogeneic stem cell transplantation (SCT). There are several techniques to deplete T-cells from the stem cell grafts e.g. physical, immunological and combined physical / immunological separation methods. All these techniques result in a stem cell graft with sufficient CD34+ stem cells combined with an adequate depletion of T and B cells. CD34+ selected stem cell grafts are very pure and do not contain any additional cell populations. In contrast, CD3+/CD19+ depleted grafts still contain NK-cells, monocytes and dendritic cells that are part of the innate immune system. Theoretically,the presence of these cells may positively influence immunological reconstitution and the graft-versus-leukaemia (GVL) effect, respectively, resulting in improved outcome after SCT Objectives: To evaluate the differences in immunological reconstitution, transplant related mortality, disease-free survival and overall survival after T-cell depleted allogeneic SCT for haematological malignancies using either immunomagnetic CD34+ selection or immunomagnetic CD3+/CD19+ depletion using the CliniMACS system in approximately 270 consecutive patients. Additionally in this study in 20 consecutive patients the kinetics of NK-cel reconstitution and differences in NK-cell repertoire will be monitored. NK-cell mediated anti-tumor reactivity will be monitored in patients transplanted with and without NK-cells in the stem cell graft (CD3+/CD19+ depletion, versus CD34+ selection). Secondary objectives are to evaluate the clinical relevance of minor histocompatibility-specific cytotoxic T-cell responses for the GVL effect, the kinetics of NK-cell reconstitution and differences in NK-cell repertoire using the different T-cell depletion protocols. Design: Single center prospective randomised phase III study Population: Patients eligible for allogeneic SCT according to the standard criteria of our institution who will receive an allogeneic T- and B-cell depleted SCT with peripheral stem cells of an HLA-identical sibling donor or an HLA-identical unrelated voluntary (VUD) donor. Intervention: T-cell depletion will be conducted using two different techniques: either immunomagnetic CD34+ selection or immunomagnetic CD3+/CD19+ depletion. Endpoints: Primary endpoints are immunological reconstitution, relapse, disease free survival and overall survival. Secondary endpoints: NK-cell reconstitution and NK-cell mediated anti-tumour reactivity. Cytotoxic T-cell responses for the GVL effect. Estimated efforts and risks for participating patients: We don't expect any extra patient efforts or risks because T-cell depletion is a standard procedure in our clinic for many years. There is extensive experience with immunological T-cell depletion techniques. We hypothesize CD3+/CD19+ depletion will favour stem cell transplant outcome. Immunological and molecular biological studies will be performed on blood samples already obtained as part of the standard protocol.
Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for their growth. Giving the drug in different ways may kill more cancer cells. This randomized phase II trial is studying two different schedules of vorinostat to see how well they work in treating patients with acute myeloid leukemia.
RATIONALE: Drugs used in chemotherapy, such as busulfan and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. A donor peripheral blood, bone marrow , or umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving antithymocyte globulin before the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects of busulfan, antithymocyte globulin, and fludarabine when given together with a donor stem cell transplant in treating young patients with blood disorders, bone marrow disorders, chronic myelogenous leukemia in first chronic phase, or acute myeloid leukemia in first remission.
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.
