Active clinical trials for "Leukemia"

This study aims to determine the safety and toxicity of incremental doses of Double Negative T (DNT) cells in human subjects with high risk acute myeloid leukemia (AML). DNT cells are mature T lymphocytes that comprise ~1% of white blood cells in humans. Injection of DNTs from healthy donors has been demonstrated to be effective against AML cells. DNT cells will be collected from healthy volunteers and injected into patients.

Acute myeloid leukemia (AML) is a heterogeneous group of diseases with distinct clinicopathologic features sharing in common an abnormal increase in myeloblasts in blood and bone marrow (BM). In about 5-10% patients, the myeloblasts exhibit chromosomal abnormalities (complex and/or monosomal karyotype, CK/MK*) that are associated with refractoriness to conventional chemotherapy and an extremely bad prognosis. Standard induction chemotherapy for AML comprises daunorubicin and cytarabine, the "7+3" regimen. However, treatment is largely ineffective for CK/MK AML with a temporary clearance of blasts achieved in only 30-40% cases and the cumulative toxicities resulting from repeated courses of chemotherapy have significantly increased the morbidity and mortality risks in subsequent allogeneic BMT. Therefore, standard treatment is unsatisfactory and there is an unmet clinical need for more effective and less toxic induction regimen. Both previous and recent studies showed that 10 day course of decitabine (20 mg/m2/day) induced remission in 70-100% patients with CK/MK AML, particularly those with TP53 mutations. In this study, patients with CK/MK AML will be treated with decitabine to induce remission. Bone marrow examination will be performed after each course until complete clearance of blasts or disease progression. Patients achieving CR/CRi (see below) will continue to receive 4 more courses, after which patients eligible for BMT and for whom donors are available will receive curative BMT. We reckon that the time it takes for 4 courses of decitabine will suffice for transplantation workup in HK. . Patients ineligible for BMT will continue to receive decitabine until leukemia progression. The response rate, leukemia free survival (LFS), overall survival (OS) and percentage of patients who can be bridged to BMT will be compared with historical 7+3 regimen control.

One-third to one-half of patients with AML relapse and in general relapsed AML patients have a poor prognosis. The treatment of relapsed AML consists of induction chemotherapy followed by Allogenic Stem Cell Transplant (ASCT). However, at present there is no standard salvage chemotherapy regimen for relapsed AML, as no study has shown any one regimen to be significantly superior. Anthracyclines, Fludarabine, Etoposide and cytarabineare active agents in AMLand have been used as monotherapy and in combination in refractory and relapsed AML patients. According to previous studies the present CR rate of different regimens ranges from 50-70%. A retrospective analysis (unpublished) conducted at IRCH, AIIMS on relapsed AML patients treated with ADE (Cytarabine, Daunorubicin and Etoposide) chemotherapy showed the CR rates of approximately 70%. Therefore, we have planned this study to test the efficacy and toxicity of ADE induction chemotherapy in relapsed AML patients in a prospective manner.

Allogeneic stem cell transplantation (SCT) remains a powerful therapeutic modality for patients with acute myeloid leukemia (AML).The superior clinical outcomes of allogeneic human SCT versus chemotherapy alone as post-remission treatment could be related to the graft-versus-leukemia (GVL) effects of recovered donor T cells. Our previous study investigated both the association of MRD status with transplant outcomes in haplo-SCT and matched sibling donor transplantation(MSDT)， and also possible differences in the transplant outcomes of patients with positive pre-MRD (as determined by MFC) who underwent haplo-SCT versus MSDT. It provided new evidence that unmanipulated haplo-SCT is superior to matched sibling donor transplantation in eradicating pre-transplantation MRD, indicating that unmanipulated haploidentical allografts have stronger GVL effects.As to the AML patients in standard-risk, who have a positive MRD before MSDT, whether these patients should be given any relapse prevention is the question to be answered in this study. Interferon α-2b exerts a relatively strong immunomodulatory effect. It can kill AL cells by regulating T-cell and/or natural killer cell functions.Consequently, interferon α-2b may have potential value for high-risk AL patients after transplantation. The study hypothesis: Using interferon α-2b following hematopoietic stem cell transplantation in patients with standard-risk AML can further reduce relapse rate and improve leukemia-free survival.

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 will evaluate the proportion of subjects with chronic myeloid leukemia chronic phase that sustain major molecular response after imatinib discontinuation. To be eligible for this protocol, the subject must have received imatinib as first line regiment for at least 3 years with sustained molecular response of 4log (RM4log) or higher for one year.

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.

The purpose of this study is to evaluate the safety, efficacy and blood kinetics of autologous T cells genetically modified to express CD19 Chimeric Antigen Receptor and PD-1 knockout engineered T cells in patients with relapsed or refractory B-Cell Non-Hodgkin Lymphoma and Leukaemia.

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