HSCT from an allogeneic donor is the standard therapy for high-risk hematopoietic malignancies and a wide range of severe non-malignant diseases of the blood and immune system. The possibility of performing HSCT was significantly limited by the availability of donors compatible with the MHC system. However, modern ex-vivo and in vivo technologies for depletion of T lymphocytes have made it possible to improve the outcomes of HSCT from partially compatible related (haploidentical) donors. In representative groups, it was shown that the success of HSCT from haploidentical donors is not inferior to standard procedures of HSCT from HLA-compatible unrelated donors. HSCT from haploidentical donors in children associated with the deficit of the adaptive immune response, which persists up to 6 months after HSCT and can be an increased risk of death of the patient from opportunistic infections. To solve this problem, the method of infusion of low doses of donor memory T lymphocytes was introduced. This technology is based on the possibility of adoptive transfer of memory immune response to key viral pathogens from donor to recipient. Such infusions have been shown to be safe and to accelerate the recovery of the pathogen-specific immune response. The expansion of virus-specific T lymphocytes in the recipient's body depends on exposure to the relevant antigen in vivo. Thus, in the absence of contact with the viral antigen, the adoptive transfer of memory T lymphocytes is not accompanied in vivo by the expansion of virus-specific lymphocytes and does not form a circulating pool of memory T lymphocytes, that can protect the patient from infections. Therefore the investigators assume that ex-vivo priming of donor memory lymphocytes with relevant antigens can provide optimal antigenic stimulation and may solve the problem of restoring immunological reactivity in the early stages after HSCT. Technically ex-vivo primed memory T lymphocytes will be generated by short incubation of CD45RA-depleted fraction of the graft (a product of T lymphocyte depletion) with a pool of GMP-quality peptides representing a number of key proteins of the viral pathogens. The following are proposed as targeted antigens: CMV pp65, EBV EBNA-1, EBV LMP12A, Adeno AdV5 Hexon, BKV LT, BKV VP1. An infusion of donor memory lymphocytes will be performed on the day +1 after transplantation. Parameters of the assessment will be safety and efficacy (immune response by day 60 and stability (responses by day 180).
This study will be conducted to evaluate the safety, tolerability, cellular kinetics (CK), activity, and pharmacodynamics (PD) of NTLA-5001 in participants with Acute Myeloid Leukemia (AML).
This study is a phase Ib/II study of Max-40279-01 in combination with Azacitidine (AZA) in patients with Myelodysplastic Syndrome (MDS) or Relapsed/Refractory Acute Myeloid Leukemia (R/R AML). This study include Phase Ib and Phase II study. The phase Ib study is designed to evaluate the safety and tolerability of MAX-40279-01 in combination with Azacitidine (AZA) in patients with Relapsed or Refractory AML. The phase II study is designed to preliminarily assess the efficacy and safety of Max-40279-01 in combination with Azacitidine (AZA) in patients with Myelodysplastic Syndrome (MDS) or Relapsed/Refractory Acute Myeloid Leukemia (R/R AML).
Patients with extramedullary leukemia were identified over 10 years (January 2003 to September 2019). Clinicopathological,genetic-molecular features were identified and survival outcomes were studied and analyzed.
In this prospective study, 30 newly untreated elderly patients with acute myeloid leukemia(AML) who were not suitable for standard chemotherapy were enrolled to observe the efficacy and side effects of venetoclax (VEN) combined with azacytidine (AZA) and chemotherapy in newly treated elderly patients with AML. Overall survival (OS), complete remission rate/complete remission with incomplete recovery of blood cell count (CR/ CRi) were used as the primary endpoints, and time to response (TTR), duration of response (DOR), mortality, and recurrence rate were used as secondary endpoints,and the incidence of adverse events were evaluated.
This project is a prospective, single-center study to evaluate the efficacy, safety and related mechanisms of azacitidine combined with low-dose dasatinib in maintenance therapy in patients with intermediate and high-risk acute myeloid leukemia(AML). The patients were randomly divided into azacitidine group and azacitidine combined with low-dose dasatinib group. The overall survival and disease-free survival were taken as the main end points, and the mortality and recurrence rate were taken as the secondary end points, meanwhile, the incidence of adverse events were evaluated. At the same time, the mRNA expressions of DNA methyltransferase (DNMT1, DNMT3a, DNMT3b), tumor suppressor genes (TP53, P15, P16, P21, CDH1, DOK6, SHP1, PTPN11) and differentiation genes (pu.1, C/EBP α, C/EBP β) were detected. Pyrophosphate sequencing was used to detect the methylation level of the promoter region of these tumor suppressor genes. Western Blot was used to detect apoptosis proteins (caspase3, caspase8) and phosphorylated proteins (pSTAT3, pSTAT5, pAKT). The proportion of apoptotic population of bone marrow cells was determined by flow cytometry. Therefore, the data in this study will reflect the efficacy and safety of azacitidine or azacitidine combined with low-dose dasatinib in real-world maintenance therapy in patients with medium and high-risk AML.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and recommended Phase 2 dose (RP2D) of MK-0482. There are 2 parts of this study. Part 1 is a dose escalation which will follow an accelerated titration design (ATD) for participants with relapsed/refractory (R/R) AML or CMML. Part 2 is a dose expansion for participants with R/R AML.
This clinical trial assesses how the immune system responds to leukemia tumors after low dose radiation delivered as part of standard of care. The information learned in this study may help them know if adding immunotherapy (a type of treatment that uses the immune system to fight cancer) can be helpful in future leukemia patients receiving radiation.
This phase II clinical trial evaluates whether a modified modality of conditioning reduces treatment-related mortality (TRM) in patients who undergo a hematopoietic stem cell transplant (HSCT) for a hematological malignancy. HSCT is a curative therapy for many hematopoietic malignancies, however this regimen results in higher rates of TRM than other forms of treatment. In recent years, less intense conditioning regimens with radiation and chemotherapy prior to HSCT have been developed. Radiation therapy uses high energy sources to kill cancer cells and shrink tumors while chemotherapy drugs like fludarabine and cyclophosphamide work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This study evaluates whether a two-step approach with lower-intensity regimens of these treatments prior to HSCT reduces the rate of TRM.
