Active clinical trials for "Leukemia"

The CD123-Targeted CAR-NK cell therapy is a new treatment that is being investigated for treatment of acute myeloid leukemia (AML). The purpose of this study is to evaluate the safety of CD123-CAR NK cells given to these patients.

In recent years, the curative effect of AML has been greatly improved. However, 20% - 30% of young patients and 40% - 50% of old patients will relapse again. Its re induction response rate is low, the survival period is short, and the prognosis is very poor. At present, there is no standard treatment scheme. Although a small number of patients can benefit from allogeneic hematopoietic stem cell transplantation (allo HSCT), most patients lack suitable donors. The choice of high-dose chemotherapy is a rescue treatment scheme, but the treatment-related hematology or non hematology related toxicity and high mortality make the scheme controversial, especially for the elderly. Some studies have proposed a new treatment method combining chemotherapy with peripheral blood hematopoietic stem cell infusion after mobilization of HLA mismatched donors. Preliminary clinical studies verified that after more than 70 cases of elderly acute myeloid leukemia were treated with microtransplantation, the complete remission rate reached 80%, the 2-year disease-free survival rate reached 39%, the early mortality rate was only 6.7%, and the median recovery time of neutrophils and platelets was 11 and 14.5 days, respectively, which was significantly different from the control group of chemotherapy alone. After that, the micro transplantation technology was extended to the treatment of myelodysplastic syndrome and lymphoma, and good results were also obtained. Compared with peripheral blood / bone marrow hematopoietic stem cells, umbilical cord blood (UCB) hematopoietic stem cells have the advantages of rapid access, convenient source, no harm to donors, and low requirements for HLA matching. The immune cells in cord blood hematopoietic stem cells are mostly Na ï ve and immature immune cells, so the incidence and severity of graft-versus-host disease (GVHD) after unrelated cord blood transplantation are low, which not only reduces the failure of transplantation due to GVHD, but also avoids a series of complications and high costs brought by complex GVHD prevention and treatment techniques. Because cord blood is rich in CD16 + CD56 + NK cells and CD3 + T cells, cord blood hematopoietic stem cell transplantation also plays an important role in GVL.

This study aims to learn about the safety, tolerability, and different dose levels' safety profiles of Venetoclax and Bomedemstat (VenBom) combination therapy in participants with relapsed or refractory acute myeloid leukemia.

This research is being done to study the efficacy and safety of unrelated umbilical cord blood stem cell microtransplantation combined with azacitidine(AZA) based treatment for advanced myelodysplastic syndromes(MDS), Chronic myelomonocytic leukemia-2(CMML-2) and secondary acute myeloid leukemia(sAML). The study protocol involved unrelated umbilical cord blood stem cell combined with azacitidine based treatment, which including azacitidine alone and azacitidine plus a targeted agent or chemotherapy agent.

A study of acalabrutinib plus venetoclax (AV) versus venetoclax plus obinutuzumab (VO) in previously untreated chronic lymphocytic leukemia or small lymphocytic lymphoma.

This phase II trials studies the effect of treosulfan-based versus clofarabine-based conditioning regimens before donor hematopoietic stem cell transplant in treating patients with myelodysplastic syndromes or acute myeloid leukemia. Chemotherapy drugs, such as treosulfan, fludarabine, and clofarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy and total-body irradiation before a donor hematopoietic stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets and may help destroy any remaining cancer cells. This study may help doctors determine whether treosulfan-based or clofarabine-based conditioning regimen works better before donor hematopoietic stem cell transplant in treating patients with myelodysplastic syndromes or acute myeloid leukemia.

This is a pilot study designed to identify the effect of daunorubicin-cytarabine liposome (CPX-351) in combination with a FLT3-inhibitor (midostaurin) as induction and consolidation therapy for patients with high-risk FLT3 mutated acute myeloid leukemia (AML) and subsequent CD34+-selected allogeneic stem cell transplant from HLA compatible related or unrelated donors.

Prognosis of patients undergoing salvage allogeneic stem cell transplantation for refractory leukemia or other refractory myeloid malignanies is poor. One of the approaches to augment graft-versus-leukemia effect the use of post-transplantation bendamustine in graft-versus-host disease prophylaxis. Despite high frequency of responses and durable remissions after this approach majority of patients develop a serious complication - cytokine release syndrome, which can be life-threatening in some patients. On the other hand post-transplantation cyclophocphamide was reported to abort cytokine release syndrome that sometimes occurs after graft transfusion in patients after haploidentical graft transfusion. The aim of this study is to evaluate if the combination of post-transplantation bendamustine (PTB) and post-transplantation cyclophosphamide (PTCY) facilitates comparable graft-versus leukemia effect to PTB, but with better safety profile and reduced incidence of severe cytokine release syndrome.

This phase II trial is to evaluate the effects of acalabrutinib in combination with venetoclax in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma that does not respond to treatment (refractory) or that has come back (recurrent). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as venetoclax, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Given acalabrutinib and venetoclax may kill more cancer cells.

This study will be divided into two parts, Parts A and B and will enroll patients with relapsed/refractory AML or MDS/chronic myelomonocytic leukemia (CMML) patients who have failed up to 2 prior therapeutic regimens. Part A is a dose escalation study to explore the safety, efficacy, pharmacokinetic (PK) and pharmacodynamic (PD) profile of DSP107 when administered in combination with azacitidine (AZA). Part B is a dose escalation study to explore the safety, efficacy, PK and PD profile of DSP107 when administered in combination with AZA and venetoclax (VEN).
