Filter by:The hypothesis of this study is that 5-aza and lenalidomide act synergistically in MDS and AML patients with chromosomal abnormalities involving monosomy 5 or del5q. Therefore, this phase I study will investigate the maximum tolerated dose (MTD) of lenalidomide in combination with a fixed dose of 5-aza in this patient population.
The purpose of this study is to determine the safety and feasibility of unrelated double and single cord blood transplantation in patients with haematological malignancies using reduced-intensity or myeloablative conditioning regimens.
The purpose of this study is to determine the safety and feasibility of conditioning with fludarabine, busulphan and thymoglobuline in patients with myelodysplastic syndrome (MDS), myelodysplastic/myeloproliferative disorders (MDS/MPD) or acute myeloid leukaemia (AML) undergoing haematopoietic stem cell allograft with granulocyte colony-stimulating factor (G-CSF)-mobilised peripheral blood stem cells (PBSC) (or bone marrow) from HLA compatible sibling donors.
RATIONALE: Allogeneic hematopoietic stem cell transplant (HSCT) is a treatment that can cure acute leukemia and myelodysplasia. After giving the patient chemotherapy and total body irradiation to stop the growth of cancer and remove the patient's diseased bone marrow, healthy stem cells from a donor are infused into the patient to replace the patient's bone marrow and make red and white blood cells and platelets. Unfortunately HSCT is often complicated by 'graft versus host disease' (GVHD) in which the transplanted cells from a donor can make an immune response against the body's normal cells and cause tissue damage and severe symptoms. Removing a subset of the donor T cells, called 'naive T cells', before transplant may reduce the frequency and intensity of GVHD. PURPOSE: This phase II trial will determine whether the removal of the naive T cells from donor cells can decrease the rate and severity of graft-vs-host disease while preserving specific immunity against infections in patients with acute leukemia or advanced myelodysplastic syndromes.
RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about nausea and vomiting caused by cancer treatment. PURPOSE: This laboratory study is looking at blood samples from patients with cancer who were treated on a clinical trial to control nausea and vomiting during donor stem cell transplant.
RATIONALE: Studying blood samples from cancer patients undergoing pain treatment in the laboratory may help doctors learn more about how pain drugs work in the body. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at fentanyl in patients with cancer.
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.
