Active clinical trials for "Precursor Cell Lymphoblastic Leukemia-Lymphoma"

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 (HAPLO) 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. The primary aim of the study is to help improve overall survival with haploidentical stem cell transplant in this high risk patient population by 1) limiting the complication of graft versus host disease (GVHD), 2) enhancing post-transplant immune reconstitution, and 3) reducing non-relapse mortality.

This phase I/II trial is studying the side effects and best dose of vorinostat when given together with rituximab, ifosfamide, carboplatin, and etoposide and to see how well they work in treating patients with relapsed or refractory lymphoma or previously untreated T-cell non-Hodgkin lymphoma or mantle cell lymphoma. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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. Drugs used in chemotherapy, such as ifosfamide, carboplatin, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving vorinostat together with rituximab and combination chemotherapy may kill more cancer cells

This pilot clinical trial studies the side effects of pegaspargase when given together with combination chemotherapy in treating patients with newly diagnosed high-risk acute lymphoblastic leukemia. Pegaspargase may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy 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. Giving more than one drug (combination chemotherapy) together with pegaspargase may kill more cancer cells.

Objectives: A. Primary objective: 1 To assess the feasibility and the effectiveness of pediatric type therapy (augmented BFM) in patients age 12 through 40 with untreated precursor-B or T acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LL). B. Secondary objective: To evaluate the prognostic significance of minimal residual disease in bone marrow samples at the end of induction and at the end of consolidation in this group of patients. To prospectively evaluate gene hypermethylation status in this group of patients. To prospectively analyze asparaginase activity and anti-asparaginase antibody formation in this population of patients.

The aim of this clinical study in adult ALL is to compare by risk category (1) the feasibility of two different CNS prophylaxis regimens and (2) the overall disease-free survival in relation to the achievement of an early MRD negative status and following consolidation with lineage-targeted methotrexate infusions and other disease-specific therapeutic elements, with or without the application of allogeneic or autologous SCT depending on risk class and MRD study results. In this multicentric prospective pilot randomized phase II trial on CNS prophylaxis, all patients receive induction/consolidation therapy incorporating lineage-targeted high-dose methotrexate plus other drugs (with additional imatinib in Ph/BCR-ABL+ ALL), for the achievement of an early negative MRD status. The MRD study supports a risk/MRD-oriented final consolidation phase.

This research study is for people with a specific type of leukemia called Philadelphia chromosome positive acute lymphoblastic leukemia (the type the patients have). The investigators plan to give you combination of 3 drugs (dasatinib, mitoxantrone, cytarabine) for the first part of the chemotherapy (called Induction). The investigators have previously shown that the combination of mitoxantrone and cytarabine is very effective in your kind of leukemia. The purpose of this study is to establish a safe dose range of dasatinib in combination with this standard induction chemotherapy based on side effects. If possible, the trial will also give us an idea of how well this combination might work in treating your leukemia. Previous studies have shown that dasatinib can produce responses when given alone for your kind of leukemia. By using the dasatinib together with the chemotherapy, the investigators believe that we can kill even more leukemia cells than with either treatment alone. The investigators will initially treat patients with a low dose of dasatinib and monitor for side-effects. If the initial group of patients is able to tolerate this low-dose of dasatinib, then future patients will receive higher doses of dasatinib. Mitoxantrone and cytarabine chemotherapy is the standard therapy at the investigators' institution for the patient's leukemia and it is the combination of dasatinib with this chemotherapy that is new and investigational in this study.

This phase I/II trial studies the side effects and best dose of donor natural killer (NK) cell therapy and to see how well it works when given together with fludarabine phosphate, cyclophosphamide, total-body irradiation, donor bone marrow transplant, mycophenolate mofetil, and tacrolimus in treating patients with hematologic cancer. Giving chemotherapy, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells. It may also 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. Giving an infusion of the donor's T cells (donor lymphocyte infusion) may help the patient's immune system see any remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving mycophenolate mofetil and tacrolimus after the transplant may stop this from happening.

This multicentric phase III study is designed to assess the efficacy and safety of recombinant asparaginase (rASNase) in comparison to Asparaginase medac™ during treatment of children with de novo ALL

The goal of this clinical research study is to find the highest tolerable dose of the drugs clofarabine and cyclophosphamide that can be given together in the treatment of relapsed or refractory ALL. The safety of the combination treatment will also be studied. Objectives: Phase I: To establish toxicities and safety of the proposed combination To establish the dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of the combination to proceed with the phase II part of the study Phase II: To establish the efficacy (complete and overall response) of the proposed combination. To analyze pharmacokinetic (PK) and pharmacodynamic (PD) properties of clofarabine as well as the impact on DNA repair of leukemic blasts with the proposed combination.

In Japan, patients with relapsed or refractory T-ALL/T-LBL represent an extremely small patient population. While the small number of patients presents a practical limitation to the size of a clinical trial, patients whose disease has not responded to or has relapsed after treatment with multiple prior chemotherapy regimens have no accepted standard therapies available. Japanese leukemia experts have expressed interest in evaluating 506U78 in Japanese patients with relapsed or refractory T-ALL/T-LBL. In order to obtain safety, tolerability, and pharmacokinetic data of 506U78 in Japanese patients, this study is designed to maximize the contribution of each available patient.
