17 Clinical Trials for Various Conditions
This is an single arm, open label, interventional phase II trial evaluating the efficacy of umbilical cord blood (UCB) hematopoietic stem and progenitor cells (HSPC) expanded in culture with stimulatory cytokines (SCF, Flt-3L, IL-6 and thromopoietin) on lympho-hematopoietic recovery. Patients will receive a uniform myeloablative conditioning and post-transplant immunoprophylaxis.
This is a Phase II study of allogeneic hematopoietic stem cell transplant (HCT) using a myeloablative preparative regimen (of either total body irradiation (TBI); or, fludarabine/busulfan for patients unable to receive further radiation). followed by a post-transplant graft-versus-host disease (GVHD) prophylaxis regimen of post-transplant cyclophosphamide (PTCy), tacrolimus (Tac), and mycophenolate mofetil (MMF).
This is a phase II trial using a non-myeloablative cyclophosphamide/ fludarabine/total body irradiation (TBI) preparative regimen with modifications based on factors including diagnosis, disease status, and prior treatment. Single or double unit selected according to current University of Minnesota umbilical cord blood graft selection algorithm.
This is a single institution phase II study of a reduced intensity conditioning (RIC) followed by a haploidentical hematopoietic cell transplant (haplo-HCT) in persons with diagnosis of hematologic malignancy. Conditioning will consists of fludarabine, cyclophosphamide, melphalan and total body irradiation (TBI) preparative regimen with a melphalan dose reduction for patients ≥55 years old and those with HCT Comorbidity Index (CI) \>3. This study uses a two-stage phase II design with accrual goal of 84 patients, using 28 patients separately for arms A, C and D
This phase II trial studies how well naive T-cell depletion works in preventing chronic graft-versus-host disease in children and young adults with blood cancers undergoing donor stem cell transplant. Sometimes the transplanted white blood cells from a donor attack the body's normal tissues (called graft versus host disease). Removing a particular type of T cell (naive T cells) from the donor cells before the transplant may stop this from happening.
This phase II trial studies how well donor peripheral blood stem cell (PBSC) transplant works in treating patients with hematologic malignancies. Cyclophosphamide when added to tacrolimus and mycophenolate mofetil is safe and effective in preventing severe graft-versus-host disease (GVHD) in most patients with hematologic malignancies undergoing transplantation of bone marrow from half-matched (haploidentical) donors. This approach has extended the transplant option to patients who do not have matched related or unrelated donors, especially for patients from ethnic minority groups. The graft contains cells of the donor's immune system which potentially can recognize and destroy the patient's cancer cells (graft-versus-tumor effect). Rejection of the donor's cells by the patient's own immune system is prevented by giving low doses of chemotherapy (fludarabine phosphate and cyclophosphamide) and total-body irradiation before transplant. Patients can experience low blood cell counts after transplant. Using stem cells and immune cells collected from the donor's circulating blood may result in quicker recovery of blood counts and may be more effective in treating the patient's disease than using bone marrow.
This is a Phase II study following subjects proceeding with our Institutional non-myeloablative cyclophosphamide/ fludarabine/total body irradiation (TBI) preparative regimen followed by a related, unrelated, or partially matched family donor stem cell infusion using post-transplant cyclophosphamide (PTCy), sirolimus and MMF GVHD prophylaxis.
The goal of this clinical trial is to determine the safety and feasibility of allogeneic transplantation with bone marrow from a deceased donor in patients with acute and chronic leukemias, myelodysplastic syndrome, and certain lymphomas. Patients will either receive myeloablative conditioning or reduced intensity conditioning regimen prior to the transplant. Patients will be followed for 56 days for safety endpoints and remain in follow-up for one year.
This is a single arm, phase II trial of HLA-haploidentical related hematopoietic cells transplant (Haplo-HCT) using reduced intensity conditioning (fludarabine and melphalan and total body irradiation). Peripheral blood is the donor graft source. This study is designed to estimate disease-free survival (DFS) at 18 months post-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.
This is a single center pilot study of a non-myeloablative umbilical cord blood transplant for the treatment of a hematological malignancy with a single infusion of T regulatory (Treg) given shortly after UCB transplantation.
This is a multi-center, single arm Phase II study of hematopoietic cell transplantation (HCT) using human leukocyte antigen (HLA)-mismatched unrelated bone marrow transplantation donors and post-transplantation cyclophosphamide (PTCy), sirolimus and mycophenolate mofetil (MMF) for graft versus host disease (GVHD) prophylaxis in patients with hematologic malignancies.
This phase II trial is for patients with acute lymphocytic leukemia, acute myeloid leukemia, myelodysplastic syndrome or chronic myeloid leukemia who have been referred for a peripheral blood stem cell transplantation to treat their cancer. In these transplants, chemotherapy and total-body radiotherapy ('conditioning') are used to kill residual leukemia cells and the patient's normal blood cells, especially immune cells that could reject the donor cells. Following the chemo/radiotherapy, blood stem cells from the donor are infused. These stem cells will grow and eventually replace the patient's original blood system, including red cells that carry oxygen to our tissues, platelets that stop bleeding from damaged vessels, and multiple types of immune-system white blood cells that fight infections. Mature donor immune cells, especially a type of immune cell called T lymphocytes (or T cells) are transferred along with these blood-forming stem cells. T cells are a major part of the curative power of transplantation because they can attack leukemia cells that have survived the chemo/radiation therapy and also help to fight infections after transplantation. However, donor T cells can also attack a patient's healthy tissues in an often-dangerous condition known as Graft-Versus-Host-Disease (GVHD). Drugs that suppress immune cells are used to decrease the severity of GVHD; however, they are incompletely effective and prolonged immunosuppression used to prevent and treat GVHD significantly increases the risk of serious infections. Removing all donor T cells from the transplant graft can prevent GVHD, but doing so also profoundly delays infection-fighting immune reconstitution and eliminates the possibility that donor immune cells will kill residual leukemia cells. Work in animal models found that depleting a type of T cell, called naïve T cells or T cells that have never responded to an infection, can diminish GVHD while at least in part preserving some of the benefits of donor T cells including resistance to infection and the ability to kill leukemia cells. This clinical trial studies how well the selective removal of naïve T cells works in preventing GVHD after peripheral blood stem cell transplants. This study will include patients conditioned with high or medium intensity chemo/radiotherapy who can receive donor grafts from related or unrelated donors.
This phase II trial studies how well clofarabine, idarubicin, cytarabine, vincristine sulfate, and dexamethasone work in treating patients with mixed phenotype acute leukemia that is newly diagnosed or has returned after a period of improvement (relapsed). Drugs used in chemotherapy, such as clofarabine, idarubicin, cytarabine, vincristine sulfate, and dexamethasone, 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.
This phase II trial studies how well T cell depleted donor peripheral blood stem cell transplant works in preventing graft-versus-host disease in younger patients with high risk hematologic malignancies. 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. Removing a subset of the T cells from the donor cells before transplant may stop this from happening.
The primary objective of the study is to determine the safety and tolerability when adding abatacept to acute Graft versus Host Disease in transplants for malignant diseases using unrelated donor bone marrow or peripheral blood stem cell grafts.
The purpose of this study is to learn about possible changes in brain anatomy and in thinking abilities, such as memory skills, in patients with cancer who receive treatment with chemotherapy alone or in combination with total body radiation before undergoing stem cell transplantation.
