Filter by:This phase I trial is studying the side effects and best dose of giving PDX101 together with 17-AAG in treating patients with metastatic or unresectable solid tumors or lymphoma. PDX101 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. Drugs used in chemotherapy, such as 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving PXD101 together with 17-AAG may kill more cancer cells.
RATIONALE: Giving chemotherapy, natural killer cells, aldesleukin, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of abnormal cells and cancer cells. It also helps stop the patient's immune system from rejecting the donor's 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, mycophenolate mofetil, and methylprednisolone before and after transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation followed by donor umbilical cord blood natural killer cells, aldesleukin, and umbilical cord blood transplant works in treating patients with refractory hematologic cancer or other diseases.
Non-randomized, open, dose ranging and dose scheduling study of ascending doses of KW-2449 in subjects with AML, ALL, MDS and CML.
RATIONALE: A donor stem cell transplant can lower the body's immune system, making it difficult to fight off infection. Giving antibiotics, such as moxifloxacin, may help prevent bacterial infections in patients who have recently undergone donor stem cell transplant. It is not yet known whether moxifloxacin is more effective than a placebo in preventing bacterial infections in patients who have recently undergone donor stem cell transplant. PURPOSE: This randomized phase III trial is studying moxifloxacin to see how well it works compared with a placebo in preventing bacterial infections in patients who have recently undergone donor stem cell transplant.
This clinical study is being conducted at multiple sites to determine the activity, safety and tolerability of XL999 when given weekly to patients with relapsed or newly-diagnosed AML. XL999 is a small molecule inhibitor against Flk1/kinase insert domain receptor (KDR), PDGFR, c-Kit, FLT3 and SRC. c-Kit and FLT3 are receptors commonly expressed on AML blasts.
The purpose of this study is to compare the efficacy of dasatinib with that of high-dose (800-mg) imatinib in participants with chronic phase chronic myeloid leukemia who achieved only a suboptimal response after at least 3 months of monotherapy with 400-mg imatinib. The safety of these treatments will also be evaluated.
This is a phase I trial in patients with relapsed or refractory leukemia of a human monoclonal antibody that kills B cell acute lymphoblastic leukemia. The trial will study the safety, pharmacokinetics, and anti-tumor activity of the antibody given as a single agent and with vincristine.
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.
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 phase II trial is studying how well sorafenib works in treating patients with relapsed chronic lymphocytic leukemia.
RATIONALE: A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy and radiation therapy, or that have become cancer. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclophosphamide and fludarabine together with total-body irradiation followed by cyclosporine and mycophenolate mofetil before the transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving combination chemotherapy together with radiation therapy followed by cyclosporine and mycophenolate mofetil works in treating patients who are undergoing a donor stem cell transplant for hematologic cancer, metastatic breast cancer, or kidney cancer.
