211^At-BC8-B10 Before Donor Stem Cell Transplant in Treating Patients With High-Risk Acute Myeloid Leukemia, Acute Lymphoblastic Leukemia, Myelodysplastic Syndrome, or Mixed-Phenotype Acute Leukemia

This phase I/II trial studies the side effects and best dose of 211\^astatine(At)-BC8-B10 before donor stem cell transplant in treating patients with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or mixed-phenotype acute leukemia. Radioactive substances, such as astatine-211, linked to monoclonal antibodies, such as BC8, can bind to cancer cells and give off radiation which may help kill cancer cells and have less of an effect on healthy cells before donor stem cell transplant.

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.

Blinatumomab, Methotrexate, Cytarabine, and Ponatinib in Treating Patients With Philadelphia Chromosome-Positive, or BCR-ABL Positive, or Relapsed/Refractory, Acute Lymphoblastic Leukemia

This phase II trial studies how well blinatumomab, methotrexate, cytarabine, and ponatinib work in treating patients with Philadelphia chromosome (Ph)-positive, or BCR-ABL positive, or acute lymphoblastic leukemia that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as blinatumomab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as methotrexate 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. Ponatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving blinatumomab, methotrexate, cytarabine, and ponatinib may work better in treating patients with acute lymphoblastic leukemia.

HA-1 T TCR T Cell Immunotherapy for the Treatment of Patients With Relapsed or Refractory Acute Leukemia After Donor Stem Cell Transplant

This phase I trial studies the side effects and best dose of CD4+ and CD8+ HA-1 T cell receptor (TCR) (HA-1 T TCR) T cells in treating patients with acute leukemia that persists, has come back (recurrent) or does not respond to treatment (refractory) following donor stem cell transplant. T cell receptor is a special protein on T cells that helps them recognize proteins on other cells including leukemia. HA-1 is a protein that is present on the surface of some peoples' blood cells, including leukemia. HA-1 T cell immunotherapy enables genes to be added to the donor cells to make them recognize HA-1 markers on leukemia cells.

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.

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.

Bridging Allogeneic Hematopoietic Stem Cell Transplantation or Not After CD19 CAR - T (S1904) Cell Therapy for r/r B-cell Acute Lymphoblastic Leukemia

Traditional salvage chemotherapy has low efficacy and poor long-term prognosis for relapsed or refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL). Targeted CD19 CAR-T cell immunotherapy is an effective means of treating R/R B-ALL. Several clinical studies have shown that its remission rate for R/R B-ALL can reach 68-93%. However, long-term follow-up found that the remission time after CD19 CAR-T treatment is short and the relapse rate is high. Therefore, how to ensure the long-term survival of R/R B-ALL patients after remission by CAR-T therapy is an urgent problem to be solved. Some studies have shown that timely bridging allo-HSCT after CAR-T treatment can overcome the risk of relapse and further improve the long-term survival of patients. However, there is currently no randomized controlled study on whether to bridge transplantation after CAR-T. The purpose of this study is to evaluate the efficacy and safety of S1904 in the treatment of relapsed or refractory CD19-positive B-cell acute lymphoblastic leukemia with or without bridging to allogeneic hematopoietic stem cell transplantation after remission.
