Active clinical trials for "Leukemia, Prolymphocytic"

This phase I multicenter feasibility trial is studying the safety and potential efficacy of infusing ex vivo expanded cord blood progenitors with one unmanipulated umbilical cord blood unit for transplantation following conditioning with fludarabine, cyclophosphamide and total body irradiation (TBI), and immunosuppression with cyclosporine and mycophenolate mofetil (MMF) for patients with hematologic malignancies. Chemotherapy, such as fludarabine and cyclophosphamide, and TBI given before an umbilical cord blood transplant stops the growth of leukemia cells and works to prevent the patient's immune system from rejecting the donor's stem cells. The healthy stem cells from the donor's umbilical cord blood help the patient's bone marrow make new red blood cells, white blood cells, and platelets. It may take several weeks for these new blood cells to grow. During that period of time, patients are at increased risk for bleeding and infection. Faster recovery of white blood cells may decrease the number and severity of infections. Studies have shown that counts are more likely to recover more quickly if increased numbers of cord blood cells are given with the transplant. We have developed a way of growing or "expanding" the number of cord blood cells in the lab so that there are more cells available for transplant. We are doing this study to find out whether or not giving these expanded cells along with one unexpanded cord blood unit is safe and if use of expanded cells can decrease the time it takes for white blood cells to recover after transplant. We will study the time it takes for blood counts to recover, which of the two cord blood units makes up the patient's new blood system, and how quickly immune system cells return

This phase II trial studies how well tacrolimus and mycophenolate mofetil works in preventing graft-versus-host disease in patients who have undergone total-body irradiation (TBI) with or without fludarabine phosphate followed by donor peripheral blood stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and TBI before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening.

This is a Pilot/Phase I, single arm, single center, open label study to determine the safety, efficacy and cellular kinetics of CART19 (CTL019) in chemotherapy resistant or refractory CD19+ leukemia and lymphoma subjects. The study consists of three Phases: 1) a Screening Phase, followed by 2) an Intervention/Treatment Phase consisting of apheresis, lymphodepleting chemotherapy (determined by the Investigator and based on subject's disease burden and histology, as well as on the prior chemotherapy history received), infusions of CTL019, tumor collection by bone marrow aspiration or lymph node biopsy (optional, depending on availability), and 3) a Follow-up Phase. The suitability of subjects' T cells for CTL019 manufacturing was determined at study entry. Subjects with adequate T cells were leukapheresed to obtain large numbers of peripheral blood mononuclear cells for CTL019 manufacturing. The T cells were purified from the peripheral blood mononuclear cells, transduced with TCR-ζ/4-1BB lentiviral vector, expanded in vitro and then frozen for future administration. The number of subjects who had inadequate T cell collections, expansion or manufacturing compared to the number of subjects who had T cells successfully manufactured is a primary measure of feasibility of this study. Unless contraindicated and medically not advisable based on previous chemotherapy, subjects were given conditioning chemotherapy prior to CTL019 infusion. The chemotherapy was completed 1 to 4 days before the planned infusion of the first dose of CTL019. Up to 20 evaluable subjects with CD19+ leukemia or lymphoma were planned to be dosed with CTL019. A single dose of CTL019 (consisting of approximately 5x10^9 total cells, with a minimal acceptable dose for infusion of 1.5x10^7 CTL019 cells) was to be given to subjects as fractions (10%, 30% and 60% of the total dose) on Day 0, 1 and 2. A second 100% dose of CTL019 was initially permitted to be given on Day 11 to 14 to subjects, providing they had adequate tolerance to the first dose and sufficient CTL019 was manufactured.

This phase I/II trial studies how well autologous stem cell transplant followed by donor stem cell transplant works in treating patients with lymphoma that has returned or does not respond to treatment. Peripheral blood stem cell transplant using stem cells from the patient or a donor may be able to replace immune cells that were destroyed by chemotherapy used to kill cancer cells. The donated stem cells may also help destroy any remaining cancer cells (graft-versus-tumor effect).

This phase II trial studies the side effects of ex vivo-activated autologous lymph node lymphocytes infusion and to see how well they work in treating patients with chronic lymphocytic leukemia. Biological therapies, such as ex vivo-activated autologous lymph node lymphocytes, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop tumor cells from growing.

This phase I/II trial studies the side effect and best dose of entospletinib when giving together with obinutuzumab and to see how well they work in treating patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or non-Hodgkin lymphoma that has come back. Entospletinib may stop the growth of cancer cells by blocking some of the enzymes need for cell growth. Monoclonal antibodies, such as obinutuzumab, may interfere with the ability of cancer cells to grow and spread. Giving entospletinib and obinutuzumab together may work better in treating patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or non-Hodgkin lymphoma.

RATIONALE: Placing a tumor antigen chimeric receptor that has been created in the laboratory into patient autologous or donor-derived T cells may make the body build immune response to kill cancer cells. PURPOSE: This clinical trial is studying genetically engineered lymphocyte therapy in treating patients with B-cell leukemia or lymphoma that is relapsed (after stem cell transplantation or intensive chemotherapy) or refractory to chemotherapy.

RATIONALE: Giving chemotherapy before a donor umbilical cord blood transplant (UCBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from an unrelated donor, that do not exactly match the patient's blood, 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 make an immune response against the body's normal cells. Giving antithymocyte globulin before transplant and cyclosporine and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor umbilical cord blood stem cell transplant works in treating patients with hematologic malignancies.

In Part B to investigate the safety and tolerability of AZD6738 when given orally to patients with prospectively identified 11q deleted or ATM deficient, relapsed/refractory CLL

This phase II trial studies how well sirolimus, cyclosporine and mycophenolate mofetil works in preventing graft-vs-host disease (GVHD) in patients with blood cancer undergoing donor peripheral blood stem cell (PBSC) transplant. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving total-body irradiation together with sirolimus, cyclosporine, and mycophenolate mofetil before and after transplant may stop this from happening.
