Inotuzumab Ozogamicin and Blinatumomab With or Without Ponatinib in Treating Patients With Newly Diagnosed, Recurrent, or Refractory CD22-Positive B-Lineage Acute Lymphoblastic Leukemia
This phase II trial studies how well inotuzumab ozogamicin and blinatumomab with or without ponatinib work in treating patients with CD22-positive B-lineage acute lymphoblastic leukemia that is newly diagnosed, has come back after a period of improvement (recurrent), or does not respond to treatment (refractory). 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. Blinatumomab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Ponatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving inotuzumab ozogamicin and blinatumomab with or without ponatinib may be effective in treating patients with newly diagnosed, recurrent or refractory CD22 positive B-lineage acute lymphoblastic leukemia.

Recombinant Erwinia Asparaginase and Venetoclax in Combination With Blinatumomab for the Treatment of Relapsed or Refractory CD19 Positive B-cell Acute Lymphoblastic Leukemia
This phase I/Ib trial tests the safety and side effects of asparaginase Erwinia chrysanthemi-recombinant-rywn (recombinant Erwinia asparaginase) and venetoclax in combination with blinatumomab and how well the combination works in treating patients with CD19 positive B-cell acute lymphoblastic leukemia (ALL) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Asparaginase Erwinia chrysanthemi, a type of protein synthesis inhibitor, is a drug that is made up of the enzyme asparaginase, which comes from the bacterium Erwinia chrysanthemi. It is used in people who cannot take asparaginase that comes from the bacterium E. coli. Asparaginase Erwinia chrysanthemi breaks down the amino acid asparagine and may stop the growth of cancer cells that need asparagine to grow. It may also kill cancer cells. 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 drug used to treat certain types of B-cell acute lymphoblastic leukemia that are CD19 positive (expresses the protein CD19). 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. Blinatumomab is a type of bispecific T-cell engager. Giving asparaginase Erwinia chrysanthemi and venetoclax in combination with blinatumomab may be safe, tolerable, and/or effective in treating patients with relapsed or refractory ALL.

Venetoclax and Vincristine in Treating Patients With Relapsed or Refractory T-cell or B-cell Acute Lymphoblastic Leukemia
This phase Ib/II trial studies the side effects and best dose of venetoclax and how well it works when given together with vincristine in treating patients with T-cell or B-cell acute lymphoblastic leukemia that has come back (recurrent) or does not respond to treatment (refractory). Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Chemotherapy drugs, such as vincristine, 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 venetoclax together with vincristine may work better in treating patients with acute lymphoblastic leukemia compared to vincristine alone.

Inotuzumab Ozogamicin in Treating Younger Patients With B-Lymphoblastic Lymphoma or Relapsed or Refractory CD22 Positive B Acute Lymphoblastic Leukemia
This phase II trial studies how well inotuzumab ozogamicin works in treating younger patients with B-lymphoblastic lymphoma or CD22 positive B acute lymphoblastic leukemia that has come back (relapsed) or does not respond to treatment (refractory). 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.

Low-Intensity Chemotherapy and Venetoclax in Treating Patients With Relapsed or Refractory B- or T-Cell Acute Lymphoblastic Leukemia
This phase I/II trial studies the side effects and best dose of venetoclax and how well it works in combination with low-intensity chemotherapy in patients with B- or T-cell acute lymphoblastic leukemia that has not responded to treatment or that has come back. Venetoclax may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, including vincristine, cyclophosphamide, dexamethasone, rituximab, methotrexate, and cytarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax with low-intensity chemotherapy may work better in treating patient with B- or T-cell acute lymphoblastic leukemia.

Inotuzumab Ozogamicin and Combination Chemotherapy in Treating Patients With Acute Lymphoblastic Leukemia
This phase I/II trial studies the side effects and best dose of inotuzumab ozogamicin and to see how well it works when given together with combination chemotherapy in treating patients with acute lymphoblastic leukemia. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a toxic agent called N-acetyl-gamma-calicheamicin dimethyl hydrazide (CalichDMH). Inotuzumab attaches to CD22 positive cancer cells in a targeted way and delivers CalichDMH to kill them. 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. Drugs used in chemotherapy 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 together with combination chemotherapy may be a better treatment for acute lymphoblastic leukemia.

Blinatumomab and Nivolumab With or Without Ipilimumab in Treating Patients With Poor-Risk Relapsed or Refractory CD19+ Precursor B-Lymphoblastic Leukemia
This phase I trial studies the side effects and best dose of blinatumomab when given with nivolumab alone or nivolumab and ipilimumab in treating patients with poor-risk CD19+ precursor B-lymphoblastic leukemia that has come back after a period of improvement (relapsed) or has not responded to treatment (refractory). Immunotherapy with monoclonal antibodies, such as blinatumomab, nivolumab, and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

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.
