An Open, Single Center, Randomized Controlled Clinical Study of UCB (Cord Blood) in the Treatment...
UCB (Cord Blood) Microtransplantation in the Treatment of Newly Diagnosed Acute Myeloid Leukemia (AML)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.

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.
Treosulfan-Based Versus Clofarabine-Based Conditioning Before Donor Hematopoietic Stem Cell Transplant...
Acute Myeloid LeukemiaMyelodysplastic SyndromeThis 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.

Acute Myeloid LeukemiaThis 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.
Post-transplantation Benadamustine and Cyclophosphamide in Patients With Refractory Myeloid Malignancies...
Myeloid LeukemiaAcute3 morePrognosis 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.
