Filter by:C-Kit is involved in an essential pathway of disease occurrence and is closely related to the poor prognosis of patients. However, the clinical significance of c-Kit mutation as molecular MRD monitoring is still unclear. What are the differences and advantages of using c-Kit mutation as MRD in prognostic assessment compared with other MRDs (MFC or RUNX1::RUNX1T1) widely used today? Existing data suggest that patients with one positive and one negative MRD results obtained by two different techniques have a higher risk of recurrence than patients with two negative MRD results but a lower risk of recurrence than patients with two positive MRD results. Therefore, can combining multiple MRD markers, including c-Kit mutations, overcome the shortcomings of a single molecular marker as MRD monitoring? Therefore, this project intends to confirm the clinical significance of quantitative detection of c-Kit mutation as MRD in acute myeloid leukemia.
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only curative therapy in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). Most of the patients requiring an allo-HSCT are above 50 years of age and are transplanted with a reduced intensity conditioning (RIC) regimen. The optimal RIC and Graft Versus Host Disease (GVHD) prophylaxis regimen allowing a good control of the disease while preventing GVHD remains to be determined for elderly patients. A phase III trial comparing the conventional RIC fludarabine-busulfan 2 days to fludarabine-treosulfan demonstrated an advantage for the flu-treosulfan arm in terms of event free survival (EFS), that should therefore be considered as the new standard of RIC regimen for AML and MDS. GVHD prevention has a crucial role in post-transplant outcomes by potentially interfering with the graft-versus-leukemia (GVL) effect and immune reconstitution. Anti-thymocyte globulins (ATG) are recommended to reduce the risk of acute and chronic GVHD in transplants performed with matched unrelated donors. However, the optimal type of ATG between the 2 approved brands (ATG-thymoglobulin and ATLG-grafalon) displaying distinct characteristics and the optimal dose of ATG are still unknown. In a retrospective study of patients transplanted mainly with RIC with matched related and unrelated donors for haematological malignancies, we observed that Anti-T lymphocyte globulin (ATLG) was associated with a reduction of grade II-IV acute GVHD in comparison to ATG without increasing the incidence of relapse. In this phase III randomised study, we propose to compare GVHD prevention with ATG versus ATLG in AML and MDS patients above 50 years of age transplanted with a matched unrelated donor following a fludarabine-treosulfan RIC, with the hypothesis that ATLG would better control GVHD in this population of patients thus limiting the risk of morbidity and mortality of the procedure.
Combining the results of previous studies and based on the clinical practice in our center, we designed the Venetoclax in combination with 3days-Decitabine regimen for induction therapy in elderly or unfit AML patients with a primary diagnosis, and set Venetoclax in combination with Azacitidine (VIALE-A) as a control group to compare the efficacy and safety and to provide evidence for the optimal selection of the clinical treatment regimen. PRIMARY ENDPOINT: To assess whether Venetoclax in combination with 3 days-diascitabine versus standard dose Venetoclax in combination with azacitidine improves event-free survival (EFS) in elderly or adult patients with unfit AML during the maximum follow-up period. Event-free survival was defined as the absence of events such as treatment failure, intolerance withdrawal, all-cause death, or achievement of CR or CRi, or relapse after MLFS, whichever occurred first, between patients' randomization and the maximum follow-up period. Treatment failure was defined as failure to achieve CR or CRi, MLFS after 2 courses of induction therapy.
The optimal induction chemotherapy regimen for newly diagnosed elderly AML patients who are eligible for intense chemotherapy is currently not well defined. Thus, we intend to conduct a multicenter, randomized, controlled clinical trial to compare the safety and efficacy of three different induction regimens (Ven+AZA vs DA/IA 3+7 vs DA/IA 2+5+VEN). A total of 90 patients will be enrolled in this study and segregated into thress groups with 30 in each group. Patients who achieve CR/CRi/CRh after using different induction regimens will receive the same consolidation and maintenance therapy. Allogeneic hematopoietic stem cell transplantation is recommended for patients in the high-risk group or those with persist MRD positivity. After completion of the treatment phase, patients entered the follow-up period.
The goal of this clinical trial is to learn about the efficacy of DASATINIB monotherapy in acute myeloid leukemia patients refractory to VENETOCLAX-AZACITIDINE. The main question it aims to answer is to assess the tumor response after 2 cycles of DASATINIB monotherapy treatment for patients with chemotherapy-ineligible acute myeloid leukemia refractory to VENETOCLAX-AZACITIDINE therapy. Participants will be given DASATINIB treatment up to 3 months. Response will be assessed by a myelogram and a complete blood count at the end of every cycle. Follow up will last 6 months.
Reduced intensive 3 + 5 idarubicin and cytarabine chemotherapy plus venetoclax as first-line treatment for adults with acute myeloid leukaemia and high-risk myelodysplastic syndrome
This is a prospective single-arm clinical study to evaluate the role of NAC after chemotherapy among patients with AML can promote hematopoietic recovery and does not affect the remission rate of the leukemia.
Myeloproliferative neoplasms (MPN) are chronic myeloid malignancies characterized by a risk of evolution to acute myeloid leukemia (AML). This unpredictable complication is associated with a grim outcome with median overall survival ranging between 2 to 10 months. To date, even allogeneic transplantation fails to significantly improve the prognosis. Biological and molecular mechanisms driving leukemic transformation are complex, ill-defined, and heterogeneous between patients. The investigator hypothesize that deciphering the molecular heterogeneity of post-MPN AML may lead identifying efficient drugs targeting of the most relevant leukemogenic pathways. Our main objective is to identify new targeted therapeutic approaches in post-MPN AML through in-depth characterization of the dysregulated pathways. The investigator will first characterize in an already annotated cohort of 120 post-MPN AML homogeneous patients subgroups using comprehensive multiomic analyses. Dysregulated pathways will be identified in each subgroup using the omics data and single-cell RNA-sequencing will be performed in a subset of patients in each subgroup. A customised drug-panel will be derived from the dysregulated pathway for an ex vivo drug screening, which will use a flow-cytometry read-out enabling to identity drug effect on cells survival, differentiation, and stemness. The 3 most promising drugs will be validated in a preclinical in vivo model of patient's derived xenograft (PDX) and their impact on clonal architecture will be studied in primary cell cultures using single-cell DNA-sequencing. Overall, this proposal may provide a better understanding of MPN leukemic transformation mechanisms and provide a path for personalized therapies. Our findings may therefore pave the way to drugs development in post-MPN AML that would provide a rationale for implementation of early clinical trials in these dreadful diseases.
This is an open-label phase I study designed to evaluate the safety of venetoclax-navitoclax with cladribine-based salvage therapy.
This is a phase 1, first-in-human (FIH), open-label, multicohort study to evaluate the safety, tolerability and preliminary efficacy of iPSC NK cells in patients with relapsed/refractory AML or AML Minimal Residual Disease (MRD).
