Blinatumomab and Combination Chemotherapy or Dasatinib, Prednisone, and Blinatumomab in Treating Older Patients With Acute Lymphoblastic Leukemia

This phase II trial studies the side effects and how well blinatumomab and combination chemotherapy or dasatinib, prednisone, and blinatumomab work in treating older patients with acute lymphoblastic leukemia. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as prednisone, vincristine sulfate, methotrexate, and mercaptopurine, 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. Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving blinatumomab with combination chemotherapy or dasatinib and prednisone may kill more cancer cells.

A Study of Revumenib in Combination With Chemotherapy for Patients Diagnosed With Relapsed or Refractory Leukemia

This phase II trial tests the safety and best dose of revumenib in combination with chemotherapy, and evaluates whether this treatment improves the outcome in infants and young children who have leukemia that has come back (relapsed) or does not respond to treatment (refractory) and is associated with a KMT2A (MLL) gene rearrangement (KMT2A-R). Leukemia is a cancer of the white blood cells, where too many underdeveloped (abnormal) white blood cells, called "blasts", are found in the bone marrow, which is the soft, spongy center of the bones that produces the three major blood cells: white blood cells to fight infection; red blood cells that carry oxygen; and platelets that help blood clot and stop bleeding. The blasts crowd out the normal blood cells in the bone marrow and spread to the blood. They can also spread to the brain, spinal cord, and/or other organs of the body. The leukemia cells of some children have a genetic change in which a gene (KMT2A) is broken and combined with other genes that typically do not interact with one another; this is called "rearranged". This genetic rearrangement alters how other genes are turned on or off in the cell, turning on genes that drive the development of leukemia. Patients with KMT2A rearrangement have higher risk for cancer coming back after treatment. Revumenib is an oral medicine that directly targets the changes that occur in a cell with a KMT2A rearrangement and has been shown to specifically kill these leukemia cells in preclinical laboratory settings and in animals. Drugs used in chemotherapy, such as vincristine, prednisone, asparaginase, fludarabine and 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. This trial is being done to find out if the combination of revumenib and chemotherapy would be safe and/or effective in treating infants and young children with relapsed or refractory KMT2A-R leukemia.

CAR T CELL Therapy for Pediatric, Adolescent and Young Adult Patients With CD19-Positive Leukemia

CAR19PK is a research study evaluating the use of lymphodepleting chemotherapy and chimeric antigen receptor (CAR) T cell therapy, a type of cellular therapy, for the treatment of refractory and/or relapsed leukemia. For this type of therapy, peripheral (circulating) immune cells are collected and then modified so that they can recognize an antigen, which is a particle present on the surface of a cancer cell. The CD19-CAR T cell product will be manufactured at the St. Jude Children's Research Hospital's Good Manufacturing Practice (GMP) facility. The main purpose of this study is to determine: * Evaluate different doses of fludarabine prior CAR T cell infusion * How your body processes fludarabine and cyclophosphamide, * How long the CAR T cells last in the body, * Whether or not treatment with this therapy is effective in treating people with refractory or relapsed leukemia, and * The side effects of this therapy.

CD5 Chimeric Antigen Receptor (CAR) T Cells in Subjects With Relapsed or Refractory T-cell Malignancies

This is a multi-center, open-label, non-randomized, phase 1/2 study of anti-CD5 CAR-T cell therapy in patients with CD5+ relapsed or refractory T-cell malignancies. A bayesian optimal interval (BOIN) 12 design will be used to explore the optimal biological dose (OBD) from starting dose level 1: 1×10\^6 (±20%) to dose level 2: 2×10\^6 (±20%) in three cohorts (autologous, previous-transplant-donor or newly matched donor-derived CD5 CAR T cells). If the manufactured cells are not sufficient to meet the preassigned standard dose criteria, patients will be given infusion at a low dose level of 5×10\^5 (±20%) /kg. The primary objective is to evaluate the safety and tolerability of CD5 CAR T cell therapy in subjects, determine the OBD and recommend phase 2 dose (RP2D) in phase 1, and evaluate the efficacy of CD5 CAR T cell therapy in phase 2. The primary endpoint is the type and incidence of dose-limiting toxicity (DLT) within 28 days, and the incidence and severity of adverse events (AEs) within 30 days after CD5 CAR T-cell infusion in phase 1, the best overall response (BOR) at 3 months (± 1 week) after CD5 CAR T-cell infusion in phase 2. A total number of 54 subjects will be enrolled.

Anti-CD19/20/22 Chimeric Antigen Receptor T Cells (TriCAR19.20.22 T Cells) for the Treatment of Relapsed or Refractory Non-Hodgkin Lymphoma, Acute Lymphoblastic Leukemia, and Chronic Lymphocytic Leukemia

This phase I trial tests the safety, side effects and best dose of anti-CD19/20/22 chimeric antigen receptor (CAR) T cells (TriCAR19.20.22 T cells) and how well they work in treating patients with non-Hodgkin lymphoma, acute lymphoblastic leukemia (ALL) and chronic lymphocytic leukemia (CLL) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein, such as CD19, CD20 and CD22, on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Giving TriCAR19.20.22 T cells may be safe, tolerable, and/or effective in treating patients with relapsed or refractory non-Hodgkin lymphoma, ALL and CLL.

211At-BC8-B10 Followed by Donor Stem Cell Transplant in Treating Patients With Relapsed or Refractory High-Risk Acute Leukemia or Myelodysplastic Syndrome

This phase I/II trial studies the side effects and best dose of a radioactive agent linked to an antibody (211At-BC8-B10) followed by donor stem cell transplant in treating patients with high-risk acute leukemia or myelodysplastic syndrome that has come back (recurrent) or isn't responding to treatment (refractory). 211At-BC8-B10 is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving chemotherapy and total body irradiation before a stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer 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 attack the body's normal cells, called graft versus host disease. Giving cyclophosphamide, mycophenolate mofetil, and tacrolimus after a transplant may stop this from happening.

Genetically Engineered Cells (Anti-CD19/CD20/CD22 CAR T-cells) for the Treatment of Relapsed or Refractory Lymphoid Malignancies

This phase I trial tests the safety, side effects and best infusion dose of genetically engineered cells called anti-CD19/CD20/CD22 chimeric antigen receptor (CAR) T-cells following a short course of chemotherapy with cyclophosphamide and fludarabine in treating patients with lymphoid cancers (malignancies) that have come back (recurrent) or do not respond to treatment (refractory). Lymphoid malignancies eligible for this trial are: non-Hodgkin lymphoma (NHL), acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), and B-prolymphocytic leukemia (B-PLL). T-cells (a type of white blood cell) form part of the body's immune system. CAR-T is a type of cell therapy that is used with gene-based therapies. CAR T-cells are made by taking a patient's own T-cells and genetically modifying them with a virus so that they are recognized by a group of proteins called CD19/CD20/CD22 which are found on the surface of cancer cells. Anti-CD19/CD20/CD22 CAR T-cells can recognize CD19/CD20/CD22, bind to the cancer cells and kill them. Giving combination chemotherapy helps prepare the body before CAR T-cell therapy. Giving CAR-T after cyclophosphamide and fludarabine may kill more tumor cells.
