Background: - Allogeneic hematopoietic stem cell transplantation (allotransplant) has been used to treat many kinds of cancer that develop in cells from the blood or immune system. After allotransplant, donor cells take over production of the recipient s blood and immune cells, and donor immune cells can directly attack and control tumor. However, for cancers that do not respond to allotransplant, there are no proven cures. - A single treatment with radiation can improve the potency of immune-cell therapies. This is probably because the tumor tissue is damaged in a way that new tumor proteins are exposed, attracting immune cells to the tumor. By giving only a single dose of radiation, the immune cells that are attracted to the tumor are allowed to survive and function in their usual way, traveling throughout the body and educating other immune cells to recognize tumor, and to activate and expand in order to kill the tumor cells. Some research has shown that radiation may have a widespread effect on stimulating the immune system, educating immune cells to recognize and control tumors that have not been radiated. Objectives: - To determine whether a single treatment of radiation will help donor immune cells control cancer after allotransplant without causing excessive side effects. Eligibility: - Recipients: Individuals 18 years of age and older who have blood cancers that have not responded to allotransplant. - Donors: Healthy individuals 18 years of age and older who were previous allotransplant donors for one of the study recipients. Design: - Donors will provide additional blood immune cells, called lymphocytes, through apheresis. Apheresis involves drawing blood, separating out the lymphocytes, and returning the rest of the blood to the donor. - Recipients will receive a single dose of radiation to the greatest amount of tumor that can be irradiated safely. Researchers will intentionally leave some tumor that will not be radiated in order to evaluate whether there is a widespread response to the treatment. - There are two treatment arms on the study. - Arm 1: Study participants who have donor lymphocytes available and who have not had major complications from the allotransplant will be given a dose of donor cells after they receive radiation, to provide an additional boost to the donor immune response. - Arm 2: Study participants who cannot receive donor lymphocytes because their donor is not available, they received an allotransplant from a partially matched relative, or they have had significant complications from the allotransplant - will receive radiation without additional donor lymphocytes. - All recipients will be followed closely for side effects and for tumor response to radiation with or without donor lymphocytes. Additional tests will be performed, including tumor biopsies, bone marrow samples, and blood draws, in order to study the immune effects of radiation and donor lymphocytes. - A separate, control group of allotransplant recipients will not receive radiation. This group will include participants whose transplant doctors plan to use donor lymphocyte therapy alone to control cancer progression. This group will donate blood immune cells through blood draws and apheresis. These cells will be examined to study the immune effects of receiving donor lymphocytes without radiation.
Background: - Allogeneic stem cell transplantation (SCT) has been used to treat many kinds of cancer or pre-cancerous conditions that develop in blood or immune system cells. Umbilical cord blood transplantation (UCBT) is a type of allogeneic transplant that is used when none of a patient s siblings are a match and an acceptable match cannot be identified from one of the bone marrow registries. Prior to receiving the cord blood stem cells, large doses of chemotherapy drugs and/or radiation have been traditionally used to eliminate most of the cancerous or abnormal cells from the recipient s system, along with most of his or her own stem cells and immune cells. Donor stem cells then replace the recipient s stem cells in the bone marrow, restoring normal blood production and immunity. In this way, an allogeneic SCT provides not only new blood cells but an entire new immune system. - In the past, allogeneic SCT was performed with very high doses of chemotherapy and/or radiation to get rid of as much of the recipient s cancer as possible and prevent rejection of the treatment. However, intensive chemotherapy or radiation can cause serious side effects, including death. A newer method uses smaller, less toxic doses of chemotherapy and/or radiation before allogeneic SCT. In these reduced-intensity stem cell transplants, the recipient s stem cells and immunity are not completely eliminated, but they are weakened enough to help prevent the donor s cells from being rejected. Objectives: - To study the safety and effectiveness of reduced-intensity stem cell transplants given with immune-depleting chemotherapy and umbilical cord blood provided by an unrelated donor. Eligibility: - Individuals between 18 and 69 years of age who have been diagnosed with any of a number of cancerous and pre-cancerous blood conditions, including lymphoma and leukemia. - Participants must not have a potential donor sibling or a readily available unrelated donor identified through one of the bone marrow donor registries. Design: - Patients will be matched with at least two umbilical cords with an acceptable cell dose. The two frozen umbilical cord blood units will be sent to the NIH prior to the date of transplant. - Patients will receive one, two, or three cycles of chemotherapy (based on the type of disease) to treat the disease and to weaken the immune system. Patients who already have a weakened immune system from other treatments will not receive this round of chemotherapy. - Patients will then receive 4 days of reduced-intensity transplant chemotherapy (also called the conditioning regimen ) to prepare for the transplant. - Two days after transplant chemotherapy, patients will receive the transplant, with the two umbilical cords infused one after the other on the same day. Patients will receive additional treatment to prevent complications. - Patients will remain in the hospital for 4 to 6 weeks after the transplant, and will be discharged for outpatient treatment when the study doctors deem it appropriate. - Patients will continue on medications at home to lower the risk of complications and infections, and will visit the NIH clinic regularly for the first 6 months after the transplant, and then less often for at least 5 years afterward.
A standard therapy is neither established in first-line patients nor in relapsed patients with PTCL, and there is still an unmet medical need to identify novel efficacious and safe therapy regimens. The aim of this study is to evaluate the potential of a Lenalidomide plus Vorinostat and Dexamethasone combination therapy as an effective and safe therapeutic regimen, in the treatment of relapsed PTCL following failure of prior regimens.
The purpose of this study is to determine whether the administration of a donor lymphocyte preparation depleted of functional host alloreactive T-cells (ATIR) after a T-cell depleted stem cell transplant from a related, haploidentical donor enhances survival by improving the immune effect against infections while preventing graft-versus-host disease .
Sarah Cannon Research Institute (SCRI) is committed to improvement and excellence in clinical research and correlative science. To this end, the SCRI Oncology Research Consortium will collect written consent from patients allowing the use of their tumor tissue sample(s) for testing/analysis at a future date. Future testing may include assays for newly identified markers of potential prognostic and/or therapeutic value. These markers may be specific to an individual cancer type, or they may be present more generally in cancer and/or other conditions.
RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase I trial is studying the safety of donor umbilical cord blood transplant after fludarabine phosphate, cyclophosphamide, and total-body irradiation in treating patients with high-risk hematologic cancer (now closed). The Phase II part of this trial is studying whether priming one of two UCB units with C3a facilitates engraftment of the treated unit.
This is an open-label, single arm phase 1 study to evaluate the dose-limiting toxicity, maximum tolerated dose, and recommended phase II dose of Clioquinol in patients with relapsed or refractory hematologic malignancies. The study will also characterize Cliquinol's safety, tolerability and pharmacodynamic effect.
This phase II trial studies the side effects and how well vorinostat works in treating patients with primary cutaneous T-cell lymphoma. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth
This phase 1 study of quarfloxin (CX-3543) is designed to test the safety, tolerability, and highest safe dose of this drug when administered intravenously weekly for three weeks of a four week cycle in patients with advanced solid tumors.
