A Platform Protocol to Investigate Post-Transplant Cyclophosphamide-Based Graft-Versus-Host Disease Prophylaxis in Patients With Hematologic Malignancies Undergoing Mismatched Unrelated Donor Peripheral Blood Stem Cell Transplantation

The purpose of this clinical trial is to compare drug combinations to learn which drugs work best to prevent graft-versus-host-disease (GVHD) in people who have received a stem cell transplant. The source of stem cells is from someone who is not related and has a different blood cell type than the study participant. The researchers will compare the new drug combination to a standard drug combination. They will also learn about the safety of each drug combination. Participants will: * Receive the standard or new drug combination after transplant * Visit the doctor's office for check-ups and tests after transplant that are routine for most transplant patients * Take surveys about physical and emotional well-being * Give blood and stool samples.

A Phase 1 Study of CG009301 for Injection in Adult Subjects With Recurrent or Refractory Haematological Malignancies

The goal of this clinical trial is to learn about the safety of drug CG009301. It also learns if drug CG009301 works to treat in Participants with relapsed or refractory adult haematological malignancies. The main question\[s\] it aims to answer are: 1. To determine the maximum tolerated dose (MTD) and/or objective best dose (OBD) of CG009301 for injection in subjects with relapsed or refractory adult haematological malignancies. 2. To establish subsequent dosing regimens for CG009301 for injection. 3. To characterise the safety profile and tolerability of CG009301 for injection. Participants will Receive treatment with CG009301 until disease progression.

The Efficacy of Therapy in Patients With Acute Myeloid Leukemia and Down Syndrome in Russia

This prospective non-randomized multicenter trial created based on protocol ML DS 2006 and aimed at standardization of current therapy approaches and creating a national network for diagnostic, treatment and monitoring of children (0-18 years) with AML and Down syndrome in Russia. Based on the results the investigators expect to increase long-term overall and event-free survival in children with AML and DS and reduce the immediate and remote toxicity of chemotherapy by reducing the dose load of chemotherapeutic drugs. The study protocol therapy for all patients includes four chemotherapy blocks: Course 1 AIE (cytarabine/idarubicin/etoposide) Course 2 AI (cytarabine/idarubicin) Course 3 HAD (high -dose cytarabine (1g)/daunorubicin) Course 4 HA (high-dose cytarabine) Safety to be monitored based on CTCAE v5.0

The Efficacy and Safety Assessment of Allogeneic γδ T Cells in Patients With MRD-positive AML After Allo-HSCT

The purpose of this study is to evaluate the efficacy and safety of allogeneic γδ T cells in patients with MRD-positive AML after allo-HSCT.

The Application of CAR-T Cell Therapy in Relapsed and Refractory Malignant Hematologic Tumors

This study is an open, single-arm, prospective, Phase I/II clinical study using "3+3" dose escalation and dose expansion to investigate the safety, maximum tolerated dose, in vivo pharmacokinetic profile, and preliminary efficacy of CAR-T cell injections for the treatment of relapsed/refractory malignant hematological neoplasms in subjects.

Targeting Acute Myeloid Leukemia Immunosuppressive Microenvironment by combinedIDO1 Inhibition and PD-1 Blockade

The combination of azacitidine and venetoclax is currently considered a therapeutic strategy innovative in AML through the addition of new compounds (triplet therapies), including inhibitors of the immune checkpoint inhibitors. Despite strong motivation, the clinical results of these approaches have been disappointing overall. The mechanisms leading to treatment failure of immunotherapies in AML are poorly elucidated as the effects on the AML microenvironment induced by basic azactidine and venetoclax therapy are largely unknown. In particular, the activity of the IDO1 enzyme as a potential mechanism of microenvironment resistance has been scarcely studied. The products of the IDO1-catalysed pathway activate the signalling of the AHR in mesenchymal stem cells and enhance their immunosuppressive effects, including the ability to reprogram the phenotype of M1/M2 macrophages. Furthermore, activation of the AHR by by products of the IDO1 pathway kinurenine-promotes tolerogenic dendritic cells and the generation of regulatory T cells. Based on this rationale, TALETE-2023 will aim to analyse the leukaemia immune microenvironment through multiomics (epigenomics transcriptomics, proteomics, metabolomics) and assess its contribution to the effect of the combination of azacitidine and venetoclax.

CD123-CD16-NK Cells Immunotherapy for AML

The goal of this clinical trial is to evaluate the effectiveness of CD123-CD16 bispecific antibody-modified NK cells in treating patients with CD123-positive relapsed or refractory Acute Myeloid Leukemia (RR AML). It will also assess the safety of this modified NK cell therapy. The main questions： Does the infusion of CD123-CD16 bispecific antibody-modified NK cells induce remission in RR AML patients? What are the safety and potential adverse effects associated with the administration of these modified NK cells? Researchers will administer CD123-CD16 bispecific antibody-modified NK cells to RR AML patients and compare the outcomes to existing treatment options to determine efficacy and safety. Participants will: Undergo lymphocyte-depleting chemotherapy Fludarabine\&Cyclophosphamide from day -5 to day -3 before NK cell infusion. Receive intravenous infusions of modified NK cells at escalating doses: The first three patients will receive 1×10⁷ cells/kg. The next three patients will receive 2×10⁷ cells/kg. The final three patients will receive 4×10⁷ cells/kg. Have NK cell infusions administered every 96-120 hours for a total of three infusions, with each infusion completed within 10 to 15 minutes. Undergo dose escalation with subsequent groups only after confirming the safety of the previous dose group. Have their vital signs (temperature, heart rate, respiratory rate, blood pressure, etc.) monitored before and after each infusion. Keep baseline data records during NK cell infusions. Participate in follow-up assessments to monitor disease remission and detect any adverse events. This trial aims to provide new treatment options for RR AML patients by leveraging the targeted cytotoxic effects of CD123-CD16 bispecific antibody-modified NK cells to achieve disease remission.

Avapritinib Combined With Azacitidine and Venetoclax in the Treatment of Relapsed AML After Allo-HSCT

This is a single-center, prospective, single-arm, exploratory clinical study. To explore the efficacy and safety of avapritinib in patients with recurrent acute myeloid leukemia after allogeneic hematopoietic stem cell transplantation with C-KIT mutation RUNX1::RUNX1T1 or CBFB::MYH11.

Efficacy of Venetoclax Combined with Intensive Chemotherapy in Different Subgroups of AML

Acute myeloid leukemia (AML) is a common hematological malignancy. Intensive chemotherapy is the main treatment in fit patients. Retrospective studies have shown that Venetoclax is highly effective in elder AML patients with IDH2 and NPM1 mutations while in those with TP53 and FLT3 mutations, the combination of azacitidine with Venetoclax showed an increased remission rate without improved survival. Since AML is a highly heterogeneous disease, it is not clear which genetic type of adult AML patients would benefit from Venetoclax combined with intensive chemotherapy. Therefore, this study intends to conduct a phase II clinical trial to investigate the efficacy of intensive chemotherapy combined with Venetoclax in adult AML patients, and reveal the efficacy of Venetoclax added to chemotherapy regimens for AML with different cytogenetic and molecular subgroups.
