Active clinical trials for "Leukemia"

The suppression of the immune system creates a permissive environment for development and progression of cancer. One population of immunosuppressive cells that have become the focus of intense study is myeloid derived suppressor cells , immature myeloid cells able to induce immune-escape, angiogenesis, and tumor progression. Two different subpopulations have been identified and studied: granulocytic and monocytic myeloid derived suppressor cells with a different immunophenotype and immunosuppressive properties

In this open-label, randomized, prospective clinical trial, CBF acute myeloid leukemia (AML) patients who have reached CR are randomised into two groups and receive high-dose cytarabine (HDAC) or high-dose cytarabine plus chidamide.The safety and efficacy of chidamide is evaluated.

The trial is a single arm, single-center, non-randomized phase I clinical trial which is designed to evaluate the safety and efficacy of C-CAR011 in treatment of adult subjects with relapsed/refractory CD19+ B cells acute lymphoblastic leukemia(r/r CD19+B-ALL)

The overall purpose of this study is to explore the therapeutic effect of CD123-targeted chimeric antigen receptor T(CAR-T) cells in the treatment of Myeloid Malignancies.

Allogenic hematopoietic stem cell transplant (Allo-HSCT) is routinely used for treatment of aggressive hematological malignancies. The biological foundation of allo-HSCT is the graft-versus-leukemia (GVL) effect, which is primarily mediated by donor T cells present in the graft and is able to eradicate malignant B cells either CD19+ or CD19-. Relapse following an allo-HSCT remains a major challenge in the treatment of B-ALL. CD19-directed CAR-T cell therapy has shown promising results for the treatment of relapsed or refractory B-cell malignancies; however, a subset of patients relapse due to the loss of CD19 in tumor cells. Co-infusion of donor-derived CD19/22 bispecific CAR-T cells or CD19-directed CAR-T cells and donor-derived-HSCT has the potential to combine the CAR-T cell mediated targeted elimination of CD19 expressing B cells with GVL effect, which could have clear advantages in reducing the risk of relapse and the evolution of CD19- escape variants or clonally related malignancies in other lineages. Therefore, a complete and durable tumor responses induced by this immunotherapy could be expected.

RATIONALE: Giving chemotherapy and total marrow and lymphoid irradiation before allogeneic hematopoietic cell transplant helps stop the growth of leukemia 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 achieve brand new hematopoietic recovery. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells, resulting in graft versus-host disease. PURPOSE: This study is to evaluate the toxicity and efficacy of total marrow and lymphoid irradiation conditioning when given together with combination chemotherapy and allogeneic peripheral blood stem cell transplant in treating patients with myelodysplastic syndrome or acute leukemia.

Based on the pediatric-inspired, PEG-L-asparaginase-intensified and MRD-directed PDT-ALL-2016 protocol, this open-label, one-arm, multi-site trial PDT-ALL-LBL is aimed to evaluate the safety and effect of oral histone deacetylase inhibitor chidamide for adult T-ALL/LBL. Compared to PDT-ALL-2016 for B-ALL, HDACi chidamide will be administrated from induction therapy to maintenance therapy, along with higher dose of consolidation regimen of cytarabine, methotrexate, cyclophosphamide.

ETP-ALL is a recently recognized high-risk subgroup and the optimal therapeutic approaches are poorly characterized. Based on the pediatric-inspired, PEG-L-asparaginase-intensified and MRD-directed PDT-ALL-2016 protocol, this open-label, one-arm, multi-site trial is aimed to evaluate the safety and effect of a novel oral histone deacetylase inhibitor chidamide for adult ETP-ALL/LBL in CHINA.

This is a single center, single arm, open-lable phase 1 study to determine the safety and efficacy of autologous or donor-derived allogeneic T cells expressing CD19 chimeric antigen receptors (referred to as "CD19-CAR-T cells") in patients with relapsed or refractory acute B-cell lymphoblastic leukemia (R/R B-ALL).

The purpose of this prospective, open-label, randomized multicenter study is to evaluate the safety and efficacy of low dose decitabine in combination with modified BUCY vs modified BUCY as a myeloablative conditioning regimen for high-risk patients with acute myeloid leukemia (AML) undergoing allogeneic hematopoietic stem cell transplantation (Allo-HSCT).
