Filter by:RATIONALE: 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. Monoclonal antibodies, such as gemtuzumab ozogamicin, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving combination chemotherapy together with gemtuzumab ozogamicin or tipifarnib may kill more cancer cells. PURPOSE: This randomized phase II/III trial is studying different combination chemotherapy regimens to compare how well they work when given with or without gemtuzumab ozogamicin or tipifarnib in treating patients with acute myeloid leukemia or high-risk myelodysplastic syndromes.
The goal of this clinical research study is to learn if the combination of Gleevec (imatinib mesylate) and low doses of Cytarabine (ara-C) may help to control leukemia while causing fewer side effects than standard high dose chemotherapy.
This randomized phase III trial is studying donor bone marrow transplant with or without G-CSF to compare how well they work in treating young patients with hematologic cancer or other diseases. Giving chemotherapy and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy 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. Giving methotrexate and tacrolimus or cyclosporine before and after transplant may stop this from happening. It is not yet known whether donor bone marrow transplant is more effective with or without G-CSF in treating hematologic cancer or other diseases.
This trial is studying the side effects and how well giving cyclophosphamide and busulfan followed by donor stem cell transplant works in treating patients with myelofibrosis, acute myeloid leukemia, or myelodysplastic syndrome. Giving chemotherapy, such as cyclophosphamide and busulfan, before a donor stem cell transplant helps stops the growth of cancer cells. It also helps 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 after the transplant may stop this from happening
Numerous studies about the potential role of NK alloreactive during a n hematopoietic stem cells graft are based on genotypical analyses of the KIR receptors and on genotypic incompatibilities between KIR and HLA for couple donor/recipient. There is still a lot of issues non resolved: Are KIR really expressed and how occur their expression during time when hematopoietic reconstitution? Is it depending on HLA of the recipient?If KIR are expressed, what are the mechanisms of alloreactivity of NK cells? Are NK able to lyse tumoral cells? Could alloreactive NK cells constitute a therapeutic tool able to induce tolerance and elimination of leukemia during hematopoietic stem cells grafts?
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.
RATIONALE: Gathering information about patients with chronic myelogenous leukemia may help doctors learn more about the disease and find better methods of treatment and on-going care. PURPOSE: This natural history study is collecting health information and disease-related information over time from patients with newly diagnosed chronic myelogenous leukemia.
A non-randomized, open-label study to investigate the effects of imatinib mesylate on the pharmacokinetics of acetaminophen/paracetamol in patients with newly diagnosed, previously untreated chronic myeloid leukemia in chronic phase (CML-CP)
Core binding factor (CBF) acute myeloid leukemias (AML) include AMLs carrying the t(8;21) translocation as well as AMLs carrying either the inversion of chromosome 16 or translocation t(16;16). CBF-AMLs are characterized by their high sensitivity to standard chemotherapeutical agents, especially to cytarabine when administered as high-dose bolus infusions, and thus by a relative good prognosis. However, relapse rates are still comprised between 30 and 50% in these patients, even if overall survival may reach approximately 65% due to the potential salvage of late relapses. The primary purpose of the protocol is to compare two modalities of timed-sequential induction in order to improve the results of the treatment of CBF-AML patients. This protocol also includes the biological characterization of the heterogeneity of these diseases (gene mutation and transcription profiles), as well as a centralized minimal residual disease monitoring and centralized evaluation of pharmacogenetic polymorphisms.
The purpose of this study is to investigate whether the addition of a vaccine after participants reduced intensity transplant will be safe and beneficial. The vaccine used in this trial, called GVAX, will be made from the participants own leukemia cells, and will be given between 1-4 months after transplant. In recent years, researchers have discovered that GVAX vaccine made from the patient's own cancer calls that have been engineered in the laboratory to produce a protein called GM-CSF, can be effective in stimulating a powerful immune response specific to that cancer.
