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

This is a pilot study designed to evaluate the safety and feasibility of performing umbilical cord blood transplants in older adults or younger infirm patients with high-risk hematopoeitic malignancies. A novel reduced-intensity preparative regimen for umbilical cord blood transplantation will be used. One to a maximum of three cord blood units, depending on cell count, will be administered to facilitate engraftment. Ten patients will be enrolled with an expected accrual rate of 3-4 patients per year and with a goal of completing accrual within 2-3 years.

The purpose of this study is to evaluate the incidence of neutrophil engraftment after transplantation of one or two cord blood units meeting a predetermined total minimum cell dose of 2.0 x 10 to the seventh total nucleated cell (TNC)/kg.

The aims of the study are to determine whether single agent imatinib (STI571; Glivec) is more effective as up-front remission induction therapy than conventional multi-agent induction chemotherapy for elderly patients with Philadelphia positive (Ph+)ALL, whether this treatment is better tolerated, and whether subsequent combination therapy with imatinib and chemotherapy of approximately a 1 year duration is tolerable and effective with respect to maintaining remissions.

This study is a single-arm, open label, phase I clinical trial to evaluate the safety and feasibility of CD19CAR-T in treatment of relapsed / refractory acute lymphoblasic leukemia.

This study is designed to explore the safety and efficacy of CD7 CAR-T Cells for patients with relapse/refractory CD7+ NK/T cell lymphoma ,T-lymphoblastic lymphoma and Acute Lymphocytic Leukemia. And to evaluate the pharmacokinetics of CD7 CAR-T cells in patients.

This is a single center, single arm, open-label phase 1 study to determine the safety and efficacy of autologous T cells expressing CD19 chimeric antigen receptors in adults with CD19+ B cell malignancies.

Recent advances in acute lymphoblastic leukemia treatment are based on a cytotoxic drug combination. Measurement of minimal residual disease in bone marrow samples at day 14 of treatment is the most powerful early predictive indicator of further relapse, and it can be applied practically to all patients with acute lymphoblastic leukemia. Even more so, it has been observed that patients who present negative minimal residual disease in bone marrow samples at day 7 during induction have a better prognosis than those achieving this at day 14. Relapse represents the main cause of treatment failure that related in the extreme with resistance to apoptosis, defining the latter as the principal mechanism of programmed cell death; it is also related with the induction of leukemic cells to senescent arrest. Pentoxifylline is a methyl-xanthine byproduct considered an unspecific inhibitor of phosphodiesterase. It inhibits nuclear factor-kappa-beta activation by different mechanisms and stimulates apoptosis induced by different drugs; thus, it can optimize the antineoplastic effect of actual treatments in order to increase the apoptosis of leukemic cells. This effect might improve the prognosis of these patients. Evaluate the safety and effect of Pentoxifylline together with antineoplastic drugs in order to study increased apoptosis and decreased senescence during the remission induction phase in pediatric patients with newly diagnosed acute lymphoblastic leukemia. To achieve this propose, we will divide patients in two groups, who will receive pentoxifylline or placebo depending on the group, in addition to conventional treatment according to the protocol standard chemotherapy schema for pediatric patients with acute lymphoblastic leukemia at our institution during the remission induction phase. In addition, we will test whether the study group exerts an impact on reaching remission earlier as compared with the control group.

B-acute lymphoblastic leukaemia (ALL) is the most common childhood malignancy. Despite enhancement of childhood B-ALL outcome, relapses remain difficult to treat. Several studies in adult acute myeloid leukaemia have shown that proliferation of immunosuppressive cells -particularly T regulatory (Treg) cells and deficient natural killer (NK) cells- was associated with poor response to chemotherapy. However, few studies have been done on childhood ALL and none on relapse of B-ALL. Moreover, a newly described immunosuppressive B cells subset (Breg cells) seems to have a role in oncogenesis in mice model, but its significance has never been evaluated in human cancers. The purpose of this study is to prospectively evaluate the immune status of children newly diagnosed with first relapse of B-cell ALL, and to compare results with those of children treated for B-ALL in complete remission. Classic lymphocytic phenotype, proportions of immunosuppressive cells (Treg cells, deficient NK cells, Cytotoxic T-lymphocyte-associated protein 4 and/or Programmed T cell death 1) and thymopoiesis will be evaluated. The investigators assume that increase of immunosuppressive cells proportions could be associated with B-ALL relapse.

The reconstitution of a functioning immune system after allogeneic stem cell transplantation takes months to years. Particularly memory B-lymphocytes reconstitute poorly with the current conditioning regimes. During the period of intense immune suppression the patients are extremely susceptible to bacterial, fungal and, most importantly, viral infections.The adoptive transfer of B-lymphocytes from the stem-cell donor might significantly enhance humoral immunity for the patient. Aim of the study is to evaluate a new cellular therapy with B-lymphocytes regarding safety. A booster vaccination after B-lymphocyte transfer will evaluate the functionality of the transferred B-lymphocytes in the patient.

The purpose of this study is to determine whether vincristine sulfate liposome could reduce less peripheral neuropathy than vincristine sulfate,and be as effective as vincristine sulfate in adults with Naïve Acute Lymphoblastic Leukemia.
