Lenalidomide, Ibrutinib, and Rituximab in Treating Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma That Is Metastatic or Cannot Be Removed by Surgery

This phase I trial studies the side effects and best dose of lenalidomide when given together with ibrutinib and rituximab in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma that has come back (relapsed), has not responded well to prior treatments (refractory), has spread to other parts of the body (metastatic), or cannot be removed by surgery. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide together with ibrutinib and rituximab may kill more cancer cells.

Testing the Effectiveness of the Anti-cancer Drug, Mirdametinib, in Treating Relapsed, Refractory Chronic Lymphocytic Leukemia

This phase II trial tests the effect of mirdametinib in treating patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Mirdametinib, a methyl ethyl ketone (MEK) inhibitor, works by blocking the action of an abnormal protein that signals cancer cells to multiply. This may help slow or stop the spread of cancer cells. Giving mirdametinib may be effective in treating patients with relapsed or refractory CLL or SLL.

Donor Stem Cell Transplant With Treosulfan, Fludarabine, and Total-Body Irradiation for the Treatment of Hematological Malignancies

This phase II trial studies how well a donor stem cell transplant, treosulfan, fludarabine, and total-body irradiation work in treating patients with blood cancers (hematological malignancies). Giving chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also 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. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells.

Acalabrutinib and Venetoclax With or Without Early Obinutuzumab for the Treatment of High Risk, Recurrent, or Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

This phase II trial studies how well acalabrutinib and venetoclax with or without early obinutuzumab work for the treatment of chronic lymphocytic leukemia or small lymphocytic lymphoma that is high risk, has come back (recurrent), or does not respond to treatment (refractory). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Venetoclax may stop the growth cancer cells by blocking BCL-2 protein needed for cell growth. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving acalabrutinib and venetoclax together with early obinutuzumab may improve clinical outcomes and control the disease.

B-Cell Activating Factor Receptor (BAFFR)-Based Chimeric Antigen Receptor T-Cells With Fludarabine and Cyclophosphamide Lymphodepletion for the Treatment of Relapsed or Refractory B-cell Hematologic Malignancies

This phase I trial tests safety, side effects and best dose of B-cell activating factor receptor (BAFFR)-based chimeric antigen receptor T-cells, with fludarabine and cyclophosphamide lymphodepletion, for the treatment of patients with B-cell hematologic malignancies that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). BAFFR-based chimeric antigen receptor T-cells 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 on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (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 chemotherapy, such as fludarabine and cyclophosphamide, helps ill cancer cells in the body and helps prepare the body to receive the BAFFR based chimeric antigen receptor T-cells. Giving BAFFR based chimeric antigen receptor T-cells with fludarabine and cyclophosphamide for lymphodepletion may work better for the treatment of patients with relapsed or refractory B-cell hematologic malignancies.

Sonrotoclax, Rituximab, and Zanubrutinib in Treating Participants With Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, and Mantle Cell Lymphoma

This phase II trial studies the side effects of an escalated ramp-up of sonrotoclax following initial debulking with zanubrutinib or rituximab in treating patients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), and mantle cell lymphoma (MCL) that is newly diagnosed, has come back after a period of improvement (relapsed) or does not respond to treatment (refractory). Rituximab is a monoclonal antibody that binds to a protein called CD20, which is found on B-cells, and may kill tumor cells. Zanubrutinib may stop the growth of tumor cells by blocking a protein called Bruton's tyrosine kinase (BTK), which is needed for tumor cell growth. Sonrotoclax works by blocking a protein called B-cell lymphoma-2 (BCL-2). This protein helps certain types of blood tumor cells to survive and grow. When sonrotoclax blocks Bcl-2 it slows down or stops the growth of tumor cells and helps them die. Giving an increased dose of sonrotoclax over a shorter period of time in combination with zanubrutinib or rituximab may be safe and tolerable in treating patients with newly diagnosed, relapsed or refractory CLL, SLL, and MCL.

Acalabrutinib in Combination With Venetoclax for the Treatment of Refractory or Recurrent Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma, The AVENUE-2 Trial

This phase II trial is to evaluate the effects of acalabrutinib in combination with venetoclax in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma that does not respond to treatment (refractory) or that has come back (recurrent). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as venetoclax, 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. Given acalabrutinib and venetoclax may kill more cancer cells.

Modified Immune Cells (CD19/CD20 CAR-T Cells) in Treating Patients With Recurrent or Refractory B-Cell Lymphoma or Chronic Lymphocytic Leukemia

This phase I trial studies the side effects and best dose of CD19/CD20 chimeric antigen receptor (CAR) T-cells when given together with chemotherapy, and to see how effective they are in treating patients with non-Hodgkin's B-cell lymphoma or chronic lymphocytic leukemia that has come back (recurrent) or has not responded to treatment (refractory). In CAR-T cell therapy, a patient's white blood cells (T cells) are changed in the laboratory to produce an engineered receptor that allows the T cell to recognize and respond to CD19 and CD20 proteins. CD19 and CD20 are commonly found on non-Hodgkin?s B-cell lymphoma and chronic lymphocytic leukemia cells. Chemotherapy drugs such as fludarabine phosphate and cyclophosphamide can control cancer cells by killing them, by preventing their growth, or by stopping them from spreading. Combining CD19/CD20 CAR-T cells and chemotherapy may help treat patients with recurrent or refractory B-cell lymphoma or chronic lymphocytic leukemia.

CD19-Directed CAR-T Cell Therapy for the Treatment of Relapsed/Refractory B Cell Malignancies

This phase I trial studies the effects of CD-19 directed chimeric antigen receptor (CAR)-T cell therapy for the treatment of patients with B cell malignancies that have come back (recurrent) or have not responded to treatment (refractory). CD-19 CAR-T cells use some of a patient's own immune cells, called T cells, to kill cancer. T cells fight infections and, in some cases, can also kill cancer cells. Some T cells are removed from the blood, and then laboratory, researchers will put a new gene into the T cells. This gene allows the T cells to recognize and possibly treat cancer. The new modified T cells are called the IC19/1563 treatment. IC19/1563 may help treat patients with relapsed/refractory B cell malignancies.
