Active clinical trials for "Leukemia, Lymphoid"

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 purpose of this study is to document the pharmacological treatment strategies used in treatment naïve and previously treated relapsed/refractory iNHL/CLL patients in the Middle East and North African (MENA) region. This study will also record encountered tumor subtype and stage and the instituted pharmacological treatments, as well as assess the clinical outcomes of treatments.

The purpose of this study is to investigate efficacy and safety of fresh frozen plasma(FFP), high dose methylprednisolone(HDMP) and rituximab for ultra-high risk chronic lymphocytic leukemia.

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.

RATIONALE: Placing a tumor antigen chimeric receptor that has been created in the laboratory into patient autologous or donor-derived T cells may make the body build immune response to kill cancer cells. PURPOSE: This clinical trial is studying genetically engineered lymphocyte therapy in treating patients with B-cell leukemia or lymphoma that is relapsed (after stem cell transplantation or intensive chemotherapy) or refractory to chemotherapy.

This is a single-arm open-label phase I study to determine the effect of CD19- CAR-T Cells infusion followed by allogeneic stem cell transplantation in safety, efficacy and engraftment potential in patients with CD19+ B-lineage leukemia and lymphoma.

This is a single arm, open-label, uni-center, phase I/II study to determine the safety and efficacy of an experimental therapy called BinD19 cells in patients with B-cell acute lymphoblastic leukemia or lymphoma, who are chemo-refractory, relapsed after allogeneic SCT, or are otherwise ineligible for allogeneic stem cell transplant.

The major aim of this research is to assess the feasibility, safety and effectiveness of CD19 CAR-T Cell Therapy for Relapsed/ Refractory Acute Lymphoblastic Leukemia/ B cell Lymphoma patients who have applied it.

This study involves adding the kinase inhibitor Ruxolitinib to Ibrutinib to treat Chronic Lymphocytic Leukemia (CLL).

The purpose of this study is to explore the effect of G-CSF combination with GM-CSF on prevention and treatment of infection in children with malignant tumor.
