B Acute Lymphoblastic Leukemia

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 pilot trial assesses the effect of the combination of blinatumomab with dasatinib or imatinib and standard chemotherapy for treating patients with Philadelphia chromosome positive (Ph+) or ABL-class Philadelphia chromosome-like (Ph-like) B-Cell acute lymphoblastic leukemia (B-ALL). Blinatumomab is a bispecific antibody that binds to two different proteins-one on the surface of cancer cells and one on the surface of cells in the immune system. An antibody is a protein made by the immune system to help fight infections and other harmful processes/cells/molecules. Blinatumomab may bind to the cancer cell and a T cell (which plays a key role in the immune system's fighting response) at the same time. Blinatumomab may strengthen the immune system's ability to fight cancer cells by activating the body's own immune cells to destroy the tumor. Dasatinib and imatinib are in a class of medications called tyrosine kinase inhibitors. They work by blocking the action of an abnormal protein that signals cancer cells to multiply, which may help keep cancer cells from growing. Giving blinatumomab and dasatinib or imatinib in combination with standard chemotherapy may work better in treating patients with Ph+ or Ph-like ABL-class B-ALL than dasatinib or imatinib with chemotherapy.

This phase III trial studies the side effects of inotuzumab ozogamicin and how well it works when given with frontline chemotherapy in treating patients with newly diagnosed B acute lymphoblastic leukemia. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug called ozogamicin. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers ozogamicin to kill them. Chemotherapy drugs, such as \[intervention\], 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 inotuzumab ozogamicin with chemotherapy may work better in treating young adults with B acute lymphoblastic leukemia.

This phase III trial studies whether inotuzumab ozogamicin added to post-induction chemotherapy and immunotherapy (chemo-immunotherapy) for patients with High-Risk B-cell Acute Lymphoblastic Leukemia (B-ALL) improves outcomes. Inotuzumab ozogamicin is a monoclonal antibody, which is a type of protein that can bind to certain targets on the surface of cells. Inotuzumab ozogamicin is a monoclonal antibody that is linked to a type of chemotherapy called calicheamicin. Inotuzumab attaches to cancer cells by binding to the CD22 protein on the surface of the cancer cell and delivering calicheamicin inside the cells to kill them. Other drugs used in the chemotherapy regimen, such as cyclophosphamide, cytarabine, dexamethasone, doxorubicin, daunorubicin, methotrexate, leucovorin, mercaptopurine, prednisone, thioguanine, vincristine, and pegaspargase or calaspargase pegol 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. Blinatumomab is a specialized type of monoclonal antibody known as a bispecific T-cell engager (BiTE). It works by simultaneously binding to CD19 on cancer cells and CD3 on normal immune cells, bringing them together to destroy leukemia cells. Blinatumomab is a standard part of chemo-immunotherapy treatment for B-ALL. This trial also studies the outcomes of patients with mixed phenotype acute leukemia (MPAL), and B-lymphoblastic lymphoma (B-LLy) when treated with ALL therapy without inotuzumab ozogamicin or blinatumomab. The overall goal of this study is to understand if adding inotuzumab ozogamicin to standard of care chemo-immunotherapy maintains or improves outcomes in High Risk B-cell Acute Lymphoblastic Leukemia (HR B-ALL). The first part of the study includes the first phase of therapy: Induction. This part will collect information on the leukemia, as well as the effects of the initial treatment, to classify patients into post-induction treatment groups. On the second part of this study, patients with HR B-ALL will receive the remainder of the chemotherapy cycles (consolidation, blinatumomab block 1, interim maintenance 1, blinatumomab block 2, delayed intensification, interim maintenance 2, maintenance), with some patients randomized to receive inotuzumab. The patients that receive inotuzumab will not receive part of consolidation or part of delayed intensification. Other aims of this study include evaluating 1) side effects of treatment using patient-reported outcomes and health-related quality of life, 2) the best ways to help patients adhere to oral chemotherapy regimens, 3) the relationship between levels of inotuzumab ozogamicin in the blood and side effects, 4) the impact of chemo-immunotherapy on the immune system and risk of infection, and 5) the impact of social determinants of health on outcomes. Finally, this study will be the first to track the outcomes of subjects with disseminated B-cell Lymphoblastic Leukemia (B-LLy) or Mixed Phenotype Acute Leukemia (MPAL) when treated with B-ALL chemotherapy.

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 \[G\]).

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 blinatumomab, inotuzumab ozogamicin, and combination chemotherapy work as frontline therapy in treating patients with B acute lymphoblastic leukemia. Immunotherapy with monoclonal antibodies, such as blinatumomab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a toxic agent called ozogamicin. Inotuzumab attaches to CD22 positive cancer cells in a targeted way and delivers ozogamicin to kill them. Drugs used in chemotherapy, such as cyclophosphamide, vincristine sulfate, doxorubicin hydrochloride, dexamethasone, cytarabine, mercaptopurine, methotrexate, and prednisone 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 blinatumomab, inotuzumab ozogamicin, and combination chemotherapy may work better in treating patients with B acute lymphoblastic leukemia than chemotherapy alone.

Evaluation of Sup19 CAR-T cells in cases where previous CD19-targeted therapy has failed or where CD19 Evaluation of Safety and Efficacy in the Treatment of Low-Grade Hematological Malignancies: A Prospective, Single-Arm Clinical Study Research

This clinical trial evaluates the effects of hemoglobin threshold-specific packed red blood cell (PRBC) transfusions on quality of life and functional outcomes in patients who have undergone chemotherapy or an allogeneic hematopoietic stem cell transplant for a high-grade myeloid neoplasm, acute myeloid leukemia, or B acute lymphoblastic lymphoma/leukemia. Some types of chemotherapy and stem cell transplants can induce low platelet counts and/or anemia that requires PRBC transfusions. Given critical shortages in blood supply, and risks associated with transfusion of PRBC, there has been much investigation into the "minimum" hemoglobin level that effectively balances safety and toxicity in patients. This clinical trial evaluates the effects of giving PRBC transfusions based on a more restrictive hemoglobin threshold (\> 7 gm/dL) compared to a more liberal hemoglobin threshold (\> 9 gm/dL) on quality of life and functional outcomes. A more restrictive threshold may be just as effective at maintaining patient quality of life and function while decreasing side effects from blood transfusions and helping to conserve blood supply resources.

This study is an investigator-initiated single center, single arm clinical study with a target population of patients with relapsed or refractory malignant hematological tumors. It is an early exploratory clinical study of the safety, tolerability and initial efficacy in the treatment of relapsed or refractory malignant hematological tumors.

Objectives: The primary objective of this study will be to evaluate the impact of pre-emptive use of anakinra on the rate of severe cytokine release syndrome (CRS) following CD19-directed chimeric antigen receptor (CAR) T-cell therapy for B-acute lymphoblastic leukemia (B-ALL) in children and young adults. Patient Population: Children and young adults \<25 years of age undergoing CAR T-cell therapy for B-ALL with bone marrow disease burden of ≥5% involvement or detectable peripheral blasts within 2 weeks of the initiation of lymphodepleting chemotherapy. Study Design: This is a pilot single arm study. The investigators will inquire into the efficacy and safety of using anakinra pre-emptively to reduce the rate of severe CRS in patients with \>/=5% bone marrow blasts or lymphoblasts in the peripheral blood. Treatment Plan: This is a single arm unblinded study in which patients will receive anakinra, 2.5 mg/kg (max 100mg), IV every 12 hours starting at the onset of persistent fever (fever \>38.5⁰ C x 2 occurrences separated by at least 4 hours in a 24 hour period). If there is persistence or progression of CRS, anakinra frequency will be increased to 2.5mg/kg IV (max 100mg), every 6 hours. Anakinra will be continued until 48 hours after resolution of CRS and ICANS, and at least 7 days post-CAR T infusion. If dose and frequency of anakinra is increased, the increased dose of anakinra will be continued until 48 hours after resolution of CRS and immune effector cell-associated neurotoxicity syndrome (ICANS) and at least 7 days post-CAR T infusion. For CRS worsening beyond dose escalation of anakinra, CRS will be managed as per standard of care management. Participants will be followed for 12 months following enrollment in the study and disease evaluations will be performed as per routine clinical care following CAR T-cell therapy.

Tisagenlecleucel (CTL019) is an anti-CD19 autologous Chimeric Antigen Receptor (CAR) T-cell therapy, which has shown dramatic early results in advanced ALLs. Early loss of B-cell aplasia (recovery of B-cells in marrow/ peripheral blood within 6 months after infusion), a marker of the loss or non-functionality of the CAR T-cells, is associated to a very high risk of relapse. A reinfusion of CTL019, even after Fludarabine-Cyclophosphamide reconditioning, frequently fails to induce further expansion as observed in UPENN studies and in the Robert Debré Hospital experience. Non-persistence of CAR T-cells may be due to immune- mediated rejection or environment-mediated suppression of their growth. Evidence for increased PD-1 expression in CAR T-cells between infusion and peak expansion has been demonstrated in clinical samples. Preclinical data and few clinical data support a role of PD- 1-PD-L1 blockade in improving the effectiveness of CAR T-cell therapy. The objectives of this phase I/II study is to determine the safety, efficacy and feasibility of Nivolumab (Opdivo®)- an anti-PD1 treatment- combined to tisagenlecleucel in a cohort of relapsed or refractory B-ALL patients, aged 1-25 years old, previously treated by tisagenlecleucel (Kymriah®), with a demonstrated early loss of B-cell aplasia (within 6 months), a surrogate marker of the loss of CAR T-cells or their non- functionality. More specifically, the main objectives are: • In cohort 1 that includes patients with a MRD negative disease status combined to an early loss (within 6 months) of B-cell aplasia : To determine the optimal starting time of Nivolumab (Opdivo®) in terms of safety and efficacy among 4 candidate time points (day 14, day 11, day 5, and day - 1). • In cohort 2 that includes relapsed patients with an early loss (within 6 months) of B-cell aplasia : To estimate the feasibility in terms of safety and efficacy of a very early start of nivolumab (day-1), prior to the reinfusion of tisagenlecleucel
