Filter by:Objectives: Primary: 1. To establish the feasibility of delayed infusion of ex vivo anergized donor peripheral blood mononuclear cells (PBMC) after CD34 selected megadose haploidentical hematopoietic stem cell transplant (HSCT) Determine the feasibility of collecting parental allogeneic stimulator cells to induce anergy to the non-shared donor:recipient haplotype Determine the feasibility of collecting donor PBMC as a source of T cells for ex vivo anergization Determine the number of transplanted individuals who meet the criteria for proceeding to delayed infusion of ex vivo anergized donor PBMC 2. To establish the safety of delayed infusion of ex vivo anergized donor PBMC by establishing the maximal number of donor T cells that can be infused without unacceptable graft-versus-host disease (GVHD) Secondary: 1. To evaluate in vitro the induction and specificity of alloantigen hyporesponsiveness in donor PBMC after ex vivo anergization 2. To assess in vitro the function of immune cells engrafted in the recipient To assess in vitro whether alloantigen hyporesponsive donor T cells are present in the recipient after HSCT To develop preliminary in vitro data on the extent of pathogen-specific immunity and its rate of recovery To describe the patterns of opportunistic infections in patients so treated
Drugs used in chemotherapy, such as flavopiridol, cytarabine, and mitoxantrone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving a new schedule of more than one drug (combination chemotherapy) may kill more cancer cells. This phase I trial is studying the side effects, best dose, and best schedule for flavopiridol when given together with cytarabine and mitoxantrone in treating patients with relapsed or refractory acute leukemia.
RATIONALE: Vaccines made from the patient's cancer cells may help the body build an effective immune response to kill cancer cells. Giving vaccine therapy together with donor lymphocyte infusion after a stem cell transplant from the patient's brother or sister may kill any cancer cells that remain after transplant. PURPOSE: This clinical trial is studying the side effects, best dose, and how well vaccine therapy with or without donor lymphocyte infusion works in treating patients with acute myeloid leukemia, acute lymphoblastic leukemia, or multiple myeloma undergoing donor stem cell transplant.
The purpose of this study is to determine the efficacy and safety of transplanting StemEx® in patients with certain hematological malignancies. For these patients, it is suggested that StemEx® can improve upon the outcome of transplanting a single, unmanipulated cord blood unit by significantly increasing the number of stem/progenitor cells available to the patient.
This study will try to improve the safety and effectiveness of stem cell transplant procedures in patients with cancers of the blood. It will use a special machine to separate immune cells (T cells) from the blood of both the donor and the patient and will use photodepletion, a laboratory procedure that selectively kills cancer cells exposed to light. These special procedures may reduce the risk of graft-versus-host-disease (GVHD), a serious complication of stem cell transplants in which the donor's immune cells destroy the patient's healthy tissues, and at the same time may permit a greater graft-versus-leukemia effect, in which the donated cells fight any residual tumor cells that might remain in the body. Patients between 18 and 75 years of age with a life-threatening disease of the bone marrow (acute or chronic leukemia, myelodysplastic syndrome, or myeloproliferative syndrome) may be eligible for this study. Candidates must have a family member who is a suitable tissue match.
Phase I Study of Lenalidomide in Acute Leukemias and Chronic Lymphocytic Leukemia.
RATIONALE: Using T cells from the patient that have been treated in the laboratory may help the body build an effective immune response to kill cancer cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving laboratory-treated T cells together with cyclophosphamide may kill more cancer cells. PURPOSE: This is a two-stage protocol, consisting of a single-institution phase I safety study and multi-institution phase IIa extension study.
Multicenter, open-label, study of alvocidib in previously treated chronic lymphocytic leukemia patients. Primary objective is to determine overall response rate. The secondary objectives are: - to assess overall safety, - to assess duration of response, progression free survival, and overall survival. Clinical benefit and pharmacokinetics parameters are also evaluated.
The purpose of this study is to determine the safest dose of the BCR-ABL inhibitor XL228, how often it should be taken, and how well people with leukemia tolerate XL228.
This phase II trial is studying how well giving MS-275 together with GM-CSF works in treating patients with myelodysplastic syndrome and/or relapsed or refractory acute myeloid leukemia. MS-275 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving MS-275 together with GM-CSF may be an effective treatment for myelodysplastic syndrome and acute myeloid leukemia
