Acute Leukemia of Ambiguous Lineage

This phase II trial tests the addition of venetoclax and/or blinatumomab to usual chemotherapy for treating infants with newly diagnosed acute lymphoblastic leukemia (ALL) with a KMT2A gene rearrangement (KMT2A-rearranged \[R\]) or without a KMT2A gene rearrangement (KMT2A-germline \[G\]). Venetoclax is in a class of medications called B-cell lymphoma-2 (Bcl-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Blinatumomab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Chemotherapy drugs 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. Adding venetoclax and/or blinatumomab to standard chemotherapy may be more effective at treating patients with ALL than standard chemotherapy alone, but it may also cause more side effects. This clinical trial evaluates the safety and effectiveness of adding venetoclax and/or blinatumomab to chemotherapy for the treatment of infants with KMT2A-R or KMT2A-G ALL.

This clinical trial studies whether less fit adults with acute myeloid leukemia (AML) or myeloid neoplasms are willing to let a computer program decide (randomization) whether they receive lower- or higher-intensity chemotherapy. Historically, treatment decision-making for patients with AML or myeloid neoplasms has divided patients into two categories, with patients considered fit receiving intensive "curative" chemotherapy, and patients considered unfit, such as older patients with a higher risk of early death from therapy, receiving non-intensive "palliative" therapy or no therapy. With the introduction of new treatment agents, it has become difficult to determine the difference between intensive and non-intensive therapy, especially for patients considered unfit for whom treatment-related side effects remain a concern. Treatment intensity is best identified through randomized trials but often patients are unwilling to undergo randomization due to preset beliefs. However, with improved supportive care and the awareness that new treatment agents may have similar risks as intensive therapy, it may be possible that more patients are willing to be randomized. This may help identify the best treatment intensity for less fit adults with AML or myeloid neoplasms, which may improve outcomes.

This phase II trial tests how well adding revumenib to usual treatment (blinatumomab) compared to usual treatment alone works in treating patients with B-cell acute lymphoblastic leukemia (B-ALL) or acute leukemia with ambiguous lineage (ALAL) with KMT2A-translocation. Revumenib binds to a protein called menin and keeps it from binding to another protein called KMT2A. This stops or slows the growth of leukemia cells with changes in the KMT2A gene. Blinatumomab binds to CD19, which is found on most B cells (a type of white blood cell) and some types of leukemia cells. It also binds to a protein called CD3, which is found on T cells (another type of white blood cell). This may help the immune system kill cancer cells. In addition to blinatumomab, usual treatment also includes dexamethasone, methotrexate, cyclophosphamide, cytarabine, mercaptopurine, calaspargase pegol, doxorubicin, thioguanine, daunorubicin, vincristine and leucovorin. Dexamethasone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Methotrexate is in a class of medications called antimetabolites. It is also a type of antifolate. Methotrexate stops cells from using folic acid to make deoxyribonucleic acid (DNA) and may kill cancer cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Chemotherapy drugs, such as cytarabine, mercaptopurine, calaspargase pegol, doxorubicin, thioguanine, and daunorubicin, 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. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Leucovorin is also being studied in the treatment of cancer. It is a type of chemoprotective agent and a type of chemosensitizing agent. Adding revumenib to usual treatment with blinatumomab may be safe, tolerable and more effective than blinatumomab alone in lowering the amount of leukemia in patients with B-ALL or ALAL with the KMT2A translocation.

This phase II trial studies how well naive T-cell depletion works in preventing chronic graft-versus-host disease in children and young adults with blood cancers undergoing donor stem cell transplant. Sometimes the transplanted white blood cells from a donor attack the body's normal tissues (called graft versus host disease). Removing a particular type of T cell (naive T cells) from the donor cells before the transplant may stop this from happening.

This is a research study to find out if adding a new study drug called revumenib to commonly used chemotherapy drugs is safe and if they have beneficial effects in treating patients with acute myeloid leukemia (AML) or acute leukemia of ambiguous lineage (ALAL) that did not go into remission after treatment (refractory) or has come back after treatment (relapsed), and to determine the total dose of the 3-drug combination of revumenib, azacitidine and venetoclax that can be given safely in participants also taking an anti-fungal drug. Primary Objective * To determine the safety and tolerability of revumenib + azacitidine + venetoclax in pediatric patients with relapsed or refractory AML or ALAL. Secondary Objectives * Describe the rates of complete remission (CR), complete remission with incomplete count recovery (CRi), and overall survival for patients treated with revumenib + azacitidine + venetoclax at the recommended phase 2 dose (RP2D).

Phase 1 dose escalation will determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of revumenib in participants with acute leukemia. In Phase 2, participants will be enrolled in 4 indication-specific expansion cohorts to determine the efficacy, short- and long-term safety, and tolerability of revumenib.

This trial is evaluating the safety and tolerability of venetoclax with chemotherapy in pediatric and young adult patients with hematologic malignancies, including myelodysplastic syndrome (MDS), acute myeloid leukemia derived from myelodysplastic syndrome (MDS/AML), and acute lymphoblastic leukemia (ALL)/lymphoblastic lymphoma (LBL). The names of the study drugs involved in this study are below. Please note this is a list for the study as a whole, participants will receive drugs according to disease cohort. * Venetoclax * Azacitidine * Cytarabine * Methotrexate * Hydrocortisone * Leucovorin * Dexamethasone * Vincristine * Doxorubicin * Dexrazoxane * Calaspargase pegol * Hydrocortisone

This phase I trial tests the safety, side effects, best dose and effectiveness of revumenib in treating patients with acute leukemia after allogeneic stem cell transplant. Revumenib is in a class of medications called menin inhibitors. Revumenib targets and binds to the protein menin, thereby preventing the interaction between menin and the mixed lineage leukemia protein. Disrupting this interaction prevents the activation of specific genes that fuel the development of leukemia cells and inhibits the survival, growth, and production of certain kinds of leukemia cells. Giving revumenib may be safe, tolerable, and/or effective in treating patients with acute leukemia after allogeneic stem cell transplant.

This phase II trial tests the safety, side effects, and how well combination chemotherapy with fludarabine, high-dose cytarabine, granulocyte colony-stimulating factor (G-CSF), and idarubicin (FLAG-Ida) followed immediately by reduced-intensity total body radiation therapy, called total body irradiation (TBI), and donor hematopoietic cell transplant (HCT) works in treating adults age 60 and older with newly diagnosed adverse-risk acute myeloid leukemia (AML) or other high-grade myeloid cancer. Despite advances in supportive care and the approval of more than 10 new drugs since 2017, the outcomes of older adults with adverse-risk acute myeloid leukemia and other high-grade myeloid cancers remains poor. Most patients are expected to die from their cancer or the consequences of treatment-related side effects. Donor HCT is a very important part of any curative-cancer treatment for these patients. However, while accepted as standard care for decades, this treatment exposes patients to long periods of drug-induced low blood cell counts and the problems associated with low blood counts, like infections and bleeding, which are associated with significant risk of chronic side effects and death. This study will use a different approach to the upfront curative-cancer treatment of older adults with an adverse-risk AML or other high-grade myeloid cancer. This study will use intense chemotherapy followed a few days later by lower-dose TBI and donor HCT. Chemotherapy drugs, such as idarubicin, fludarabine, high-dose cytarabine 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. G-CSF helps the bone marrow make more white blood cells in patients with low white blood cell count due to cancer treatment. This approach allows effective treatment of cancer cells and overall reduction of the period of low blood cells counts. This decreases the risk for problems associated with low blood counts, such as infection and chronic side effects. Decreasing these are important for older adults who undergo HCT. This treatment strategy may improve treatment outcomes by allowing more patients to successfully undergo donor HCT and reduce the risk of low blood cell counts and the problems associated with low blood counts. Giving chemotherapy followed immediately by reduced-intensity TBI and donor HCT may be safe, tolerable and/or effective in treating adults age 60 and older with newly diagnosed adverse-risk AML or other high-grade myeloid cancer.

This phase II trial studies how well giving an umbilical cord blood transplant together with cyclophosphamide, fludarabine, and total-body irradiation (TBI) works in treating patients with hematologic diseases. Giving chemotherapy, such as cyclophosphamide, fludarabine and thiotepa, and TBI before a donor cord blood transplant (CBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after transplant may stop this from happening in patients with high-risk hematologic diseases.

The prognosis of acute leukaemias of ambiguous lineage is poor. The effect of chemotherapy regimen and hematopoietic stem cell transplantation are still unclear. Therefore, we will explore new therapy to improve the remission rate of acute leukaemias of ambiguous lineage. Venetoclax can significantly improve the remission rate and prolong PFS and OS. At present, venetoclax combined with azacitidine or decitabine has become the preferred treatment regimen for elderly AML patients. It also shows a high response rate in relapsed/refractory AML or MDS patients. There are few clinical studies on the treatment of ALAL. The purpose of this study is to explore the efficacy and safety of venetoclax combined with azacitidine in the treatment of newly diagnosed ALAL patients.

In this prospective, single arm, open label, clinical trial, a total of 50 acute leukemia of ambiguous lineage patients will be enrolled. Patients will receive acute lymphoblastic leukemia (ALL) -based chemotherapy and are permitted to receive allogeneic hematopoietic stem cell transplantation (HSCT) after CR . Otherwise, they will finish the consolidation chemotherapy. Patients with t(9;22) will receive chemotherapy combined with tyrosine kinase inhibitors. The purpose of current study is to evaluate the clinical efficacy of ALL-based chemotherapy，effect of genetic abnormality and minimal residual disease (MRD) on prognosis in patients with acute leukemia of ambiguous lineage.

The goal of this clinical trial is to test the ability to restore gut microbiota to healthier levels in patients with blood cancers scheduled to have stem cell transplant. The main questions it aims to answer are: * Tolerability and acceptability of intestinal microbiota transplantation (IMT) versus placebo (as assessed via patient perspective questionnaires * Changes in gut microbiome diversity across all timepoints * Markers of general health, infective/microbiological and haematological outcomes including, days of fever, admission to intensive care unit, survival, non-relapsed mortality, and incidence of graft-versus-host disease across all time points measured. Participants will be asked at their routine follow up visits to, * Provide stool, urine and blood samples at the scheduled study visits * Complete questionnaires at selected visits * Swallow either Placebo or IMT capsules once at the second study visit which will occur 2 weeks prior to the stem cell transplant (+/-3 days) Researchers will compare IMT capsules and Placebo to investigate the change in gut microbiota diversity.
