Filter by:The purpose of the study is to evaluate the effects of increasing doses of CNF1010 on pharmacodynamic markers and hematological response.
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.
This is a multi-center, open-label, single arm Phase 1/2 study evaluating the feasibility, safety, and tolerability of a series of 16 immunizations of Id-KLH with GM-CSF in patients with previously untreated B-CLL. The length of the controlled portion of the study is two years. The study will be conducted at investigative sites in the United States.
This phase I trial is studying the side effects and best dose of SJG-136 in treating patients with relapsed or refractory acute leukemia, myelodysplastic syndromes, blastic phase chronic myelogenous leukemia, or chronic lymphocytic leukemia. Drugs used in chemotherapy, such as SJG-136, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
The purpose of this study is to determine how well subjects respond to treatment with Rituximab plus Beta-Glucan.
This phase I/II trial is studying the side effects and best dose of fenretinide and to see how well it works when given together with rituximab in treating patients with B-cell non-Hodgkin lymphoma. Drugs used in chemotherapy, such as fenretinide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some find cancer cells and kill them or carry cancer-killing substances to them. Others interfere with the ability of cancer cells to grow and spread. Giving fenretinide together with rituximab may kill more cancer cells.
RATIONALE: Drugs used in chemotherapy, such as methotrexate and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well methotrexate works as first-line therapy and fludarabine works as second-line therapy in treating patients with T-cell large granular lymphocytic leukemia.
RATIONALE: Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving rituximab together with GM-CSF may be an effective treatment for chronic lymphocytic leukemia. PURPOSE: This phase II trial is studying how well giving rituximab together with GM-CSF works in treating patients with B-cell chronic lymphocytic leukemia.
