Filter by:In this trial the investigators seek to determine if injecting cord blood cells directly into the bone marrow (intraosseous injection), rather than infusing them intravenously, can improve engraftment. The rational for doing this is that most hematopoietic stem cells (HSCs) infused intravenously never reach the bone marrow, getting trapped by other organs, such as the lungs, instead. The potential advantage of intraosseous infusion is suggested by studies in rodents that have demonstrated that in HSC transplants where the cell dose is limiting intraosseous injection is a more effective route of administration. The safety of intraosseous injections, in general, is underscored by the vast experience using intraosseous injections for resuscitation of critically ill children. The safety of injecting HSCs intraosseously has been demonstrated in a clinical trial of transplanting bone marrow cells. To safeguard against problems that might result, if intraosseous infusion fails to improve engraftment in this trial, the investigators will integrate a recently introduced strategy proven to improve engraftment-the transplantation of two cord blood units. Transplanting two unrelated cord blood units by intravenous infusion has been shown to improve engraftment (although there is still room for improvement). In this trial one unit will be injected intraosseously and the other unit will be infused intravenously. This study is being conducted as a forerunner to a larger, multi-center trial. The investigators intend to enroll five patients over 1-2 years.
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.
The goal of this clinical research study is to learn if LBH589 can help to control lower-risk (low or intermediate-1 risk) MDS. The safety of this drug will also be studied.
Primary aim: 1. To determine the immunologic response, using a PR1-HLA-A2 tetramer assay, to 4 subcutaneous (SQ) injections of TVC-PR1 vaccine formulated in Montanide ISA 51 VG followed by granulocyte macrophage colony-stimulating factor (GM-CSF) in low risk and intermediate-1 myelodysplastic syndrome (MDS) patients. Secondary aims: 1. To determine if non-immunologic responders to 4 subcutaneous (SQ) injections of TVCPR1 vaccine formulated in Montanide ISA 51 VG followed by GM-CSF can be converted to immunologic responders by administering 4 additional doses of TVC-PR1 vaccine formulated in Montanide ISA 51 VG followed by GM-CSF. 2. To determine the clinical response to 4 or 8 subcutaneous (SQ) injections of TVC-PR1 vaccine formulated in Montanide ISA 51 VG followed by GM-CSF in patients low risk and intermediate-1 MDS.
This is a phase II study of lenalidomide in patients with myelodysplastic syndrome (MDS) and with acute myeloid leukemia (AML) with trilineage dysplasia. Patients will receive two cycles of lenalidomide. Patients who respond may given additional cycles of lenalidomide until disease progression.
This is a Phase I study designed to determine the MTD and assess the toxicity associated with clofarabine followed by fractionated cyclophosphamide in patients > 1 year of age or < 21 years of age with relapsed or refractory acute leukemias. There will be 25 to 35 patients enrolled. Cohorts of 3 to 6 patients each will receive escalated doses of clofarabine followed by fractionated cyclophosphamide until the MTD is reached. There will be no intra-patient dose escalation. Single-agent cyclophosphamide will be administered by 2-hour IVI on Day 0 of cycle 1. On Days 1, 2, and 3 and Days 8, 9, and 10 clofarabine will be administered by IVI 2 hours before each dose of cyclophosphamide (see the treatment schema below). A cycle is defined as 28 days.
Lenalidomide has shown significant efficacy in the treatment of anemia associated with both 5q- and non 5q- MDS patients. The mechanism(s) of action of lenalidomide in MDS is still to be determined, but given the differences in response rates seen, it is probable that the mechanism is different for patients with 5q- disease compared to non 5q- patients. T-cell mediated activation of intramedullary apoptosis in patients with early MDS leading to impaired hematopoiesis has been well described. Immunomodulation with agents such as ATG, cyclosporine and thalidomide have demonstrated clear activity in some patients with MDS. Lenalidomide, among its many effects, is a potent immunomodulator, which may contribute to its ability to improve red blood cell counts in patients with MDS. It is possible that this effect could be augmented with the addition of cyclosporine A (CSA), in a similar manner to CSA effects in patients with other bone marrow failure syndromes such as aplastic anemia. Subjects will be treated with lenalidomide 10 mg PO daily days 1-28 of a 28-day cycle. Cyclosporine A will be started on day 1 of cycle 2 (day 29) at a dose of 5 mg/kg per day given orally in 2 divided doses. Cyclosporine A levels will be assessed weekly and doses will be adjusted to maintain a serum trough level between 100-450 mg/ml. Patients will continue on therapy for minimum of 16 weeks unless toxicity occurs which precludes continuation on therapy, disease progression and/or patient withdrawal of consent. Patients not achieving response after completing 16 weeks of therapy will discontinue treatment. Patients achieving response will continue therapy until disease progression, unacceptable toxicity or loss of response.
RATIONALE: Bortezomib and vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving bortezomib together with vorinostat may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with vorinostat works in treating patients with high-risk myelodysplastic syndrome or acute myelogenous leukemia.
The goal of the Phase I part of this clinical research study is to find the highest safe dose of bendamustine that can be given to patients with acute myelogenous leukemia (AML), Acute lymphoblastic leukemia (ALL), Chronic myelogenous (or myeloid) leukemia (CML) in blastic phase, Chronic Myelomonocytic Leukemia (CMML), and myelodysplastic syndromes (MDS). The goal of the Phase II part of this clinical research study is to learn if bendamustine can help to control AML, ALL and MDS. The safety of this drug will continue to be studied.
