Active clinical trials for "Leukemia"

This study was a multi-center, open, randomized-control study on the effects and safety of idarubicin 60mg/M2 combined with BUCY pretreatment program or BUCY pretreatment program on the overall survival rate and disease-free survival rate of acute myeloid leukemia patient in high-risk group over a period of 2 years.

Allo - hematopoietic stem cell transplantation is currently the only way to cure myelodysplastic syndrome /acute leukemia . The existing experimental results showed that decitabine and 5-azacytidine up-regulated the expression of tumor Ags on leukemic blasts in vitro and expanded the numbers of immunomodulatory T regulatory cells in animal models. Reasoning that decitabine might selectively augment a graft versus leukemia effect, the investigators used decitabine administration after allogeneic stem cell transplantation to studied the immunologic sequelae.

Trial try to assess the efficacy of dasatinib in terms of major molecular response rate at 6 months in patients with CP-CML who have achieved complete cytogenetic response without major molecular response after at least 18 months on Imatinib 400/600.

Chronic Lymphocytic Leukemia (CLL) is still an incurable disease. However recent advances have established correlation between the quality of the response (in particular achievement of negativity of minimal residual disease (MRD) and progression free and overall survival. That is why MRD negative complete remission (CR) is the current goal in CLL treatment. The association of Rituximab fludarabine cyclophosphamide leads to the best response rate with 52 to 72% CR in "medically" fit untreated CLL patients. MRD results in this setting are still preliminary and around 50%. However many other situations (unfit, elderly, relapse, haematological toxicity leading to early interruption of treatment…) are associated with much lower response rate that would be improved by consolidation treatment. Monoclonal antibodies are the treatment of choice for consolidation because of sparing marrow and targeting CLL cells. Alemtuzumab has been used for this purpose and results confirm improvement of CR and MRD negative responses but alemtuzumab induced immunodeficiency lead to unacceptable infectious complications. Rituximab monotherapy induces low response rate at standard dose regimen. This is at least partially due to shaving of CD20, mechanism by which CD20 is lost from the leukemic cells but these cells are not cleared. Using low doses of rituximab reduced shaving and allowed CLL cells clearance by the mononuclear phagocytic system. Such low doses of rituximab can be administered subcutaneously. The investigators then propose subcutaneous low dose rituximab in consolidation to CLL patients responding after induction but having not achieved MRD negative CR.

It is an open-label, randomized, multi-center study. The efficacy and safety of two flumatinib doses, 400 mg once daily and 600 mg once daily, will be compared with imatinib 400 mg once daily in newly diagnosed (within 6 months) patients with Philadelphia chromosome-positive (Ph+) Chronic Myelogenous Leukemia in the chronic phase (CML-CP).

The proposed phase II trial is a multicenter, randomized, open-label study that will evaluate the efficacy and safety of azacitidine alone or in combination with lenalidomide in high-risk Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML) with a karyotype including del(5q). The primary objective will be to evaluate the efficacy in terms of response according to International Working Group (IWG) criteria for MDS and AML after 6 cycles of azacitidine or azacitidine + lenalidomide treatment, or at end of study if this occurs at an earlier time point.

RATIONALE: Conditioning with total body irradiation (TBI) and fludarabine, cyclophosphamide and anti-thymocyte globulin may induce the engraftment cross the immunologic barrier in the setting of HLA-haploidentical allogeneic hematopoietic cell transplantation. In addition, T-cell depletion may contribute to prevent developing severe acute graft versus host disease (GVHD) in haploidentical transplantation. PURPOSE: This phase I/II trial is to evaluate the safety and efficacy of TBI, fludarabine, cyclophosphamide and antithymocyte globulin with T-cell depleted graft from haploidentical donors in treating patients with acute leukemia and myelodysplastic syndrome.

RATIONALE: Low-dose cytarabine works in a minority of elderly patients with an acute myeloid leukemia unfit for intensive induction therapy by killing of leukemia cells. Addition of BIBF1120 to low-dose cytarabine might enhance the killing of leukemia cells. PURPOSE: This phase I / II trial is studying how safe BIBF1120 can be combined with low-dose cytarabine (phase I) and how well the combination of low-dose cytarabine and BIBF1120 works in elderly patients with acute myeloid leukemia unfit for intensive chemotherapy (phase II).

RATIONALE: Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as hydroxychloroquine, may stimulate the immune system in different ways and stop cancer cells from growing. It is not yet known whether imatinib mesylate is more effective when given with or without hydroxychloroquine in treating patients with chronic myeloid leukemia. PURPOSE: This randomized phase II trial is studying the side effects of giving imatinib mesylate with or without hydroxychloroquine and to see how well it works in treating patients with chronic myeloid leukemia.

Background: Allogeneic hematopoietic stem cell transplantation (or allotransplant; donor blood stem cells) have been used with varying degrees of success as an immune therapy for blood-system cancers (leukemias, myelodysplastic syndrome, lymphomas, multiple myeloma, etc.). Some people s cancer remains active (comes back or continues to spread) after an allotransplant, while other peoples cancer disappears and they are hopefully cured. National Institutes of Health (NIH) researchers are studying the reasons for these different treatment outcomes, and trying to develop better cancer treatments for people with active cancer after allotransplant. Researchers are collecting data from people who have had allotransplants for a cancer of the blood, whether or not the cancer is in remission, and from their donors. Those with active cancers may be eligible to participate in one of several NIH studies testing treatments for active cancer after allotransplant. Objectives: To develop a systematic, comprehensive evaluation of individuals with relapsed malignant blood cancers after allotransplant (and, if available, their donors) to identify potential treatment study options To compare the immune system after allotransplant between people whose cancers are growing with people whose cancers remain in remission. To compare the immune system after cancer relapse/progression treatment between people whose cancer responds to treatment with those whose cancers continue to grow. Eligibility: Individuals whose blood system cancer grows or comes back after receiving allotransplant treatment. Individuals whose blood system cancer is responding or in remission 100 days or more after receiving allotransplant treatment. Related stem-cell donors of eligible allotransplant recipients. Design: Participants will be evaluated with a full physical examination, detailed medical history (for recipients, including a history of allotransplant treatment process, side-effects, etc.), and blood tests. Recipients will also have imaging studies, possible tissue biopsies, quality of life questionnaires/assessments, and other tests to evaluate the current state of their cancer, whether active or in remission. In some cases, it may be possible to substitute results from recent tests and/or biopsies. Healthy related donors will have apheresis to provide white blood cells for study and/or for use in potential treatment options. If stem cells would be medically helpful to a recipient, their donors might be asked to take injections of filgrastim before the apheresis procedure to stimulate the production of stem cells for collection. As feasible, all recipients will be asked to return to the NIH for detailed follow-up visits in conjunction with 6, 12, and 24 months post-allotransplant evaluations, and may be monitored between visits. Recipients whose cancers are active and who are found to be eligible for treatment protocols at the NIH will continue to be monitored on this study while participating on treatment protocols. Return visits and follow-up tests for this study will be coordinated with those required by the treatment protocol. Participants may return in the future to be evaluated for new treatment study options (recipients) or additional cell donations for therapy (donors).
