Filter by:The main objectives of this study are to evaluate the side effects of MKC-1 and to determine a safe dose of MKC-1 for future studies in patients with hematological malignancies
Primary Objective: 1. To assess the self-reported symptoms and the plasma cytokine levels of AML/MDS patients pretransplantation and posttransplantation with allogeneic blood and marrow in order to identify changes in symptoms (or symptom clusters) and changes in cytokines that may be related to the conditioning regimen and/or to the development of GVHD during the 100 days posttransplant. Based on the current literature, both animal and human research, in this study we hypothesize that increases in TNF alpha to be associated with poor appetite, sleep disturbance and fatigue, but not with increases in pain, depression and numbness.
Primary Objectives: 1. To administer multiple doses of an intravenous formulation of busulfan (Bu) at a dose adjusted to yield a blood drug level with a median daily area under the plasma concentration curve (AUC) of approximately 6,500 µMol-min. This dose will be given intravenously over three hours once daily for four (4) days, in combination with Fludarabine at a dose of 40 mg/m2 as preparation for bone marrow or peripheral stern cell transplantation in patients with acute myeloid leukemia or myelodysplastic syndromes. 2. To determine the outcome of Acute Myeloid Leukemia (AML)/myelodysplastic syndromes (MDS) patients undergoing treatment with this regimen. Data regarding engraftment, toxicity, relapse rate, long-term (disease-free) outcome, and overall survival will be collected. 3. To determine the safety profile of this regimen when utilized as preparation for allogeneic transplantation. 4. To describe the plasma pharmacokinetics of busulfan when administered intravenously in this regimen.
This study is a phase I, open-label, single-arm, dose escalation trial to determine the safety and activity of lenalidomide combined with lintuzumab in patients with MDS. Small groups of 3-6 patients will be treated with pre-specified doses of lenalidomide and lintuzumab and will receive 3-week cycles of combination therapy.
RATIONALE: Studying biopsy, bone marrow, and blood samples from patients with cytopenia that did not respond to treatment may help doctors learn more about the disease and plan the best treatment. PURPOSE: This laboratory study is assessing immune function in young patients with cytopenia that did not respond to treatment.
The goal of this clinical research study is to learn if combining cord blood units will be safe and result in the cells "taking" faster in recipients. The cord blood units will have their cell number increased in the lab using cells from a family member or they will be collected from an unrelated healthy donor.
The goal of this clinical research study is to find the highest tolerable dose of gimatecan that can be given to treat myelodysplastic syndrome (MDS).
The study hypotheses is that the introduction of dose escalated treosulfan, in substitution to busulfan, will reduce toxicity after allogeneic transplantation while improving myeloablation and and disease control in patients with AML and MDS not eligible for standard transplantation.
RATIONALE: Beclomethasone dipropionate may be effective in preventing acute graft-versus-host disease in patients undergoing a stem cell transplant for hematologic cancer. PURPOSE: This randomized phase II trial is studying how well beclomethasone dipropionate works in preventing acute graft-versus-host disease in patients undergoing a donor stem cell transplant for hematologic cancer.
This study will test the safety and effectiveness of two vaccines on slowing disease progression, improving blood counts, reducing the need for transfusions of blood and platelets, or achieving remission in patients with myelodysplastic syndrome (MDS, also known as myelodysplasia), acute myeloid leukemia (AML) or chronic myeloid leukemia (CML). The vaccines consist of peptides (parts of proteins) found in MDS, AML and CML stem cells, combined with a substance called "MontanideTM". They are administered with granulocyte- macrophage colony- stimulating factor (GM-CSF). The Montanide and the GM-CSF help the immune system respond to the vaccines. People 18 years of age or older with MDS, AML or CML may be eligible for this study. Participants receive six injections of the vaccines, one dose every other week for a total of 10 weeks. The injections are given in the upper arm, upper leg, or abdomen. A separate injection of GM-CSF is given in the same area as the vaccine injections. Subjects are observed for 2 hours after the first vaccination and at least 30 minutes after each subsequent vaccination for allergic reactions. In addition to the vaccination, subjects undergo the following: - History and physical exam, chest x-ray, blood tests and bone marrow aspirate and biopsy before starting the vaccinations. - Safety monitoring during vaccine administration (every other week for 10 weeks) with blood tests and check of vital signs. - Follow-up safety monitoring (weeks 12 and 16) with blood tests every visit, chest x-ray at week 12 and bone marrow biopsy visit 16.
