Active clinical trials for "Myelodysplastic Syndromes"

This study is a Phase III, randomized, open-label, multi-center, prospective study of single umbilical cord blood (UCB) transplantation versus double UCB transplantation in pediatric patients with hematologic malignancies.

The goal of this clinical research study is to find out if decitabine, given with or without valproic acid, can help to control AML or MDS. The safety of both treatments will also be studied.

This study will determine the safety and effectiveness of an experimental vaccine in controlling the abnormal growth of cells in patients with myelodysplastic syndrome (MDS, also known as myelodysplasia), acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and chronic myeloid leukemia (CML). It will test whether the vaccine can increase the number of immune cells responding to the cancer and thereby slow progression of the illness, improve blood counts, reduce the need for transfusions of blood and platelets, or even achieve a disease remission. The vaccine contains part of a protein that is produced in large amounts by cells of patients with these cancers and an added substance called Montanide that helps the immune system respond to the vaccine. Sargramostim, another substances that boosts the immune response, is also given. Patients 18 to 85 years of age with MDS, AML, ALL or CML may be eligible for this study. Candidates are screened with a medical history, physical examination, blood tests, chest x-ray and bone marrow biopsy. Women of childbearing age also have a pregnancy test. Participants undergo the following: Chemotherapy entering the study. Leukapheresis to collect large amounts of white blood cells for infusion before vaccine administration. Participants may need placement of a central line (plastic tube, or catheter) in the upper part of the chest to be used for giving chemotherapy, blood or platelet transfusions, antibiotics and white blood cells, and for collecting blood samples. Weekly vaccine injections for nine weeks, given in the upper arm, upper leg or abdomen. Sargramostim injections following each vaccination. Standard of care treatment for MDS, AML, ALL or CML, which may include blood or platelet transfusions, growth factors, and drugs to control underlying disease and potential side effects of the vaccine. Weekly safety monitoring, including vital signs check, brief health assessment, blood tests and observation after the vaccination, on the day of each vaccination. Follow-up evaluations with blood tests and chest x-ray 3 weeks after the last vaccine dose and with blood tests and bone marrow biopsy 7 weeks after the last vaccine dose.

The purpose of this study is to investigate the effects of iron chelation using deferasirox in low and INT-1 risk (referring to the international prognostic scoring system, IPSS) MDS patients who show signs of iron overload due to repeated blood transfusions. This trial is not recruiting patients in the United States.

A phase I/II study to explore the feasibility and efficacy of autologous CIK cells in patients with acute myeloid leukemia (AML)/ high grade myelodysplastic syndrome (MDS) Group 1: As adjuvant therapy in minimal residual disease state after autologous PBSCT. Group 2: As an adoptive immunotherapy in untreated disease state when conventional therapy with curative intent is not applicable

The primary endpoint of this study is to estimate morphologic complete remission rate. Estimation of response rate is also a secondary objection.

The goal of this safety/pharmacology study is to determine MTD of sapacitabine when administered in patients with advanced leukemias or myelodysplastic syndromes.

This phase III trial is studying how well combination chemotherapy works in treating young patients with Down syndrome and acute myeloid leukemia or myelodysplastic syndromes. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.

RATIONALE: Giving low doses of chemotherapy and radiation therapy before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells when they do not exactly match the patient's blood. The donated stem cells may replace the patient's immune system 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 antithymocyte globulin before transplant and cyclosporine and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects of giving combination chemotherapy together with total-body irradiation before donor umbilical cord blood transplant and to see how well they work in treating patients with advanced hematologic cancer, metastatic breast cancer, or kidney cancer.

RATIONALE: Giving chemotherapy and total-body irradiation before a donor bone marrow transplant or peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant may stop this from happening. PURPOSE: This randomized phase III trial is studying donor bone marrow that is treated in the laboratory using two different devices to compare how well they work in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.
