Active clinical trials for "Leukemia"

Background: Mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), multiple myeloma (MM), and other lymphoid malignancies are all incurable lymphoid malignancies that mainly affect persons in their late 60s and early 70s. Conventional chemotherapy can achieve high rates of clinical response, but relapse following these responses is almost universal. Patients with lymphoid malignancies relapse because their tumor cells become resistant to chemotherapy; therefore, new types of drugs are needed for better treatment responses. The investigational drug ON 01910.Na has been shown to be active against MCL and CLL cells, but further research is needed to determine the most safe and effective dose for this drug. Objectives: To determine the maximum tolerated dose (the highest dose that does not cause unacceptable side effects) of ON 01910.Na in patients with cancers of the lymphoid cells. To study the effects that ON 01910.Na has on cancers of the lymphoid cells. Eligibility: Patients 18 years of age and older who have been diagnosed with cancer of the lymphoid cells, and who have not been able to take or have not benefitted from existing treatment options. Design: Evaluations before the treatment period: Full medical history and physical examination, and pregnancy test for women. Blood and urine tests. Disease evaluation with computerized tomography (CT) scan, magnetic resonance imaging (MRI), electrocardiogram; bone marrow and lymph node biopsies; and skeletal x-rays, if clinically indicated. Treatment with ON 01910.Na: Different research subjects will receive increasing doses of ON 01910.Na to determine which dose is considered safe. To reduce the risk of one rare serious side effect of treatment for myeloid malignancies, patients will take allopurinol 12 hours before and 7 days after each drug infusion, one 300 mg pill each day. Cycles 1 2: Patients will be admitted to the clinical center for 2 days at the beginning of each cycle. Each cycle involves intravenous infusion of ON 01910.Na continuously for a period of 48 hours, followed by 12 days of observation. Researchers will try to maintain the schedule of 2 days of infusion every 14 days, but the interval between doses may be extended if patients experience delayed recovery blood counts. Cycles 3 4: Patients who are doing well and choose to continue may receive an additional two cycles (2 days of inpatient infusion followed by 12 days of outpatient observation). At the end of cycle 4, researchers will determine if the disease is responding to therapy. Patients who experience side effects may continue to take ON 01910.Na at a lower dose or may stop receiving the drug. Patients who respond well to four cycles of ON 01910.Na may be eligible for additional cycles of ON 01910.Na. Patients who need to start another medication to treat their disease will stop taking ON 01910.Na, and the researchers will perform a final study visit 2 weeks after the last dose of ON 01910.Na. After that, participation in the study will be complete.

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 purpose of this study was to determine the efficacy and safety of twice daily (bid) oral midostaurin in patients with Aggressive Systemic Mastocytosis (ASM) or Mast Cell Leukemia (MCL) with or without an Associated Hematological clonal Non-Mast cell lineage Disease (AHNMD).

In this study, patients were randomly assigned to either receive fludarabine or not (20 mg/m2/d) in addition to induction chemotherapy, consolidation chemotherapy and the 3 subsequent re-induction courses during maintenance.

RATIONALE: Monoclonal antibodies, such as alemtuzumab and 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. Giving alemtuzumab together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying the side effects of giving alemtuzumab together with rituximab and to see how well it works in treating patients with previously untreated B-cell chronic lymphocytic leukemia.

Standard therapy with Imatinib (IM) significantly prolongs the survival of Ph+CML patients who obtain a complete cytogenetic response (CCgR). Elderly patients (i.e., at least 65 years) have similar cytogenetic responses and survival, but they usually show a low compliance. The aim of the study is to evaluate the percentage of elderly patients who maintain a CCgR with intermittent imatinib therapy with respect to standard daily administration.

RATIONALE: Vaccines made from a patient's white blood cells (dendritic cells) and a specific leukemia antigen (Wilms tumor antigen-1) may induce an effective immune response to kill residual leukemic cells and/or prevent leukemia relapse. PURPOSE: This phase I/II trial is studying the feasibility, safety and efficacy of intradermal mRNA-transfected dendritic cell vaccination therapy in patients with acute myeloid leukemia.

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.
