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

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. This phase II trial is studying several different combination chemotherapy regimens to see how well they work in treating patients with newly diagnosed acute lymphoblastic leukemia

This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. Giving low doses of chemotherapy, such as fludarabine, and TBI before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.

The purpose of this clinical research study is to understand the safety and efficacy of BMS-354825 in patients with chronic, accelerated, or blast phase chronic myelogenous leukemia (CML) or Philadelphia positive acute lymphoblastic leukemia (ALL) who are resistant to or intolerant of imatinib mesylate (Gleevec).

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Phase I trial to study the effectiveness of imatinib mesylate in treating patients who have advanced cancer and liver dysfunction

Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have chronic lymphocytic leukemia, lymphocytic lymphoma, acute lymphoblastic leukemia, or acute myeloid leukemia.

The study evaluates the efficacy and tolerability of an intensified induction and consolidation therapy. Thereafter patients receive individualised treatment stratified according to relapse risk with stem cell transplantation for patients with high and very high risk of relapse. Patients with standard risk receive further consolidation and reinduction chemotherapy. In parallel minimal residual disease (MRD) is evaluated. After six months and one year the decision on intensification or discontinuation of therapy is made based on the results of MRD evaluation.

The study evaluates the efficacy and tolerability of alternating short cycles of high-dose and conventional chemotherapy in combination with rituximab in CD20 positive patients, followed by local radiation therapy in the case of initial mediastinal or central nervous system (CNS) involvement or a residual tumor after chemotherapy. A dose-reduced regimen is offered for patients estimated to be over 55 years, biologically.

Patients with acute lymphoblastic leukaemia or very aggressive lymphoma and documented isolated CNS relapse or CNS relapse combined with other relapse sites should receive therapy with intrathecal DepoCyte at least once. Treatment may be repeated during induction phase each 2 weeks and monthly during maintenance phase. The study aim is to replace the usual 2-3 weekly applications of intrathecal triple therapy with one application of DepoCyte. Primary objective is the response rate after one application of DepoCyte. Further objectives are the compilation of data regarding safety and toxicity

Childhood leukemias which cannot be cured by chemotherapy alone may be effectively treated by allogeneic bone marrow transplantation. Moreover, for patients with chronic myelogenous leukemia (CML), allogeneic hematopoietic stem cell transplantation (HSCT) is the only proven curative modality of treatment. Patients who have received hematopoietic stem cells from an HLA matched sibling donor have proven to be less at risk for disease relapse and regimen related toxicity. However, about 70% of patients in need of HSCT do not have an HLA matched sibling donor. This necessitates the search for alternative donors, which may increase the risk of a poor outcome. The nature of the hematopoietic stem cell graft has been implicated as a primary factor determining these outcomes. The standard stem cell graft has been unmanipulated bone marrow, but recently several advantages of T-lymphocyte depleted bone marrow and mobilized peripheral blood progenitor cells (PBPC) have been demonstrated. However, T-cell depletion may increase the risk of infectious complications and leukemic recurrence while an unmanipulated stem cell graft may increase the risk of graft vs. host disease (GVHD). A key element in long range strategies in improving outcomes for patients undergoing matched unrelated donor (MUD) HSCT is to provide the optimal graft. The primary objective of this clinical trial is to estimate the incidence of acute GVHD in pediatric patients with hematologic malignancies who receive HSCT with an unmanipulated marrow graft. The results of this study can be used as the foundation for future trials related to engineering unrelated donor graft.

The objectives of Part 1 of the study were: To determine the rate of hematologic response (HR) lasting ≥4 weeks in participants with Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) in the accelerated phase (AP). To evaluate duration of HR, overall survival, cytogenetic response (CyR), time to blast crisis in CML participants in the AP, improvement of symptomatic parameters, tolerability and safety of STI571 treatment. The objective of the extension (Part 2) was: -To enable participants to have access to study drug and continue study treatment and to decrease data collection to include only overall survival and serious adverse events.
