Filter by:Primary Objective: - To determine if there is significant toxicity associated with the administration of CD34-TK75 transduced donor lymphocytes after allogeneic BMT for relapsed hematologic malignancies Secondary Objectives: - To determine if the patient develops any evidence of anti-leukemic effect from the administration of CD34-TK75 transduced donor lymphocytes - To determine if ganciclovir administration to patients who develop Graft versus Host Disease (GVHD)results in clinical improvement after infusions of CD34-TK75 transduced lymphocytes. Sub-Study Objective The primary purpose is to perform PET imaging of CD34-TK transduced allogeneic donor T cells in patients who have relapsed hematologic malignancies after allogeneic hematopoietic stem cell transplantation (SCT). At this time the limited amount of cGMP quality virus produced by the NGVL will likely permit the imaging of only 3 patients. Consequently our current objective will be to establish that the TK-expressing cells can be detected by 18FHBG-PET in patient organs relevant for performing additional studies that are currently in the planning stages and for which we are working to produce additional virus. The ultimate objective will be to use the TK substrate 18FHBG to locate the donor T cells within the recipient as they exert anti-leukemic effects, and the T cells can then be eliminated in response to in vivo administration of ganciclovir, before morbidity and mortality from GvHD occurs. We will use the imaging strategy to define patterns of T cell trafficking in humans pre and post-DLI infusion, and to determine where the cells reside while they mediate GVL in contrast to GvHD. We expect to obtain in vivo PET imaging markers predictive of GvHD before clinical symptoms occur.
Primary Objective: Determining the maximum tolerated dose (MTD) and pharmacokinetics (PK) of FTS (S-Trans, Trans-Farnesylthiosalicylic Acid) after daily oral administration on Days 1 through 21 of a 28-Day cycle to patients with advanced hematologic malignancies that have progressed following effective therapy or for which no effective therapy exists.
The main purpose of this trial is to study whether the drug sitagliptin can be given safely to patients undergoing umbilical cord blood transplantation to speed up engraftment (recovery of blood counts after transplant).
This phase II trial is studying how well giving treosulfan together with fludarabine phosphate and total-body irradiation followed by donor stem cell transplant works in treating patients with high-risk acute myeloid leukemia, myelodysplastic syndrome, acute lymphoblastic leukemia. Giving chemotherapy, such as treosulfan and fludarabine phosphate, and total-body irradiation before a donor bone marrow or 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. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and methotrexate before and after transplant may stop this from happening
This clinical trial is studying how well giving fludarabine phosphate and melphalan together with total-body irradiation followed by donor stem cell transplant works in treating patients with hematologic cancer or bone marrow failure disorders. Giving low doses of chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells or abnormal 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 or abnormal cells (graft-versus-tumor effect)
The primary objective of this study is to evaluate the efficacy and safety of ON 01910.Na Concentrate when it is administered as an intravenous continuous infusion (IVCI) over 72 hours once every 2 weeks in a broad population of MDS patients. Rationale for this study is based on the activity observed in another study with ON 01910.Na in patients with refractory anemia with excess blasts (RAEB) 1 and 2 MDS. This study will examine ON 01910.Na in a broader population of MDS and AML patients. This phase I/II study will establish the Maximum Tolerated Dose (MTD) starting with a dose of 800 mg/m2 per day administered over 24 hours for 2 consecutive days as a continuous intravenous infusion, once a week for 3 weeks of a 4-week cycle and examine the efficacy and safety profile at the MTD.
This is an open-label, Phase I study to determine the highest amount of the study drug, ON 01910.Na, that can be safety given to patients with high risk myelodysplastic syndromes (MDS) or refractory leukemias. Patients will receive ON 01910.Na (at a starting dose of 650 mg/m2) intravenously by 3-day continuous infusion once every 2 weeks. Successive courses will use longer infusion times and/or higher doses of the drug until toxicity, effectiveness, or ineffectiveness is recognized. In addition, the amount of drug in the blood will be measured, any antitumor activity will be documented, and the biological effect of ON 01910.Na on cell-cycle pathways will be evaluated in peripheral blood mononuclear cells.
The purpose of this study is to determine whether Clofarabine in combination with Busulfan is effective as a preparative transplant regimen for the treatment of leukemia and myelodysplastic syndromes
RATIONALE: Gathering information about patients with myelodysplastic syndrome or acute myeloid leukemia who are discharged after finishing chemotherapy, or who stay in the hospital until blood counts return to normal, may help doctors learn more about a patient's quality of life, use of medical services, and the cost of these services. PURPOSE: This clinical trial is studying early discharge and outpatient care in patients who have undergone chemotherapy for myelodysplastic syndrome or acute myeloid leukemia.
The purpose of this study is to find out the maximum tolerated dose (MTD) of the combined therapy of lenalidomide (Revlimid®) and Granulocyte/macrophage colony stimulating factor and CD40 Ligand expressed in the K562 cell line (GM.CD40L) bystander vaccine. This research is also being done to see how well the combination of these drugs works to fight myelodysplastic syndrome (MDS).
