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

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.

This is a single arm, open-label, phase 1/2 study to evaluate the safety and efficacy of anti-CD19 CAR-T cells in patients with relapsed or refractory B cell Malignancies.

A chimeric antigen receptor gene-modified T cells (CART: 4SCAR19)by targeted the CD19 (cluster of differentiation antigen 19), treat patients with CD19 positive malignant B cells tumor, assess treatment safety, and observe therapeutic effects. At the same time,the change process of the CART and residual tumor status of the patient are observe dynamically， which summarizes the best therapeutic effect.

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.

ATG based conditioning regimen in HLA related allogeneic hematopoietic stem cell transplantation for aggressive T-cell tumors: multi-center, open, randomized controlled clinical study

The overall objective of this study is to continue to improve the cure rate of childhood acute lymphoblastic leukemia (ALL) in Singapore and Malaysia in the context of a multi-centre cooperative trial using a risk-stratified therapy based primarily on early response to therapy utilizing a simplified minimal residual disease (MRD-lite) platform.

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.

This study aims to evaluate the safety and clinical activity of CD19 Chimeric Antigen Receptor (CAR) redirected autologous T-cells in treating patients with recurrent or refractory CD19 positive B cell ccute lymphoblastic leukemia,and dynamically observe the changes of CAR-T in patients and the residual tumor.

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.
