NCT ID: NCT00438958 Completed - Lymphoma Clinical Trials

Sibling Donor Peripheral Stem Cell Transplant or Sibling Donor Bone Marrow Transplant in Treating Patients With Hematologic Cancers or Other Diseases

Start date: March 2007
Phase: Phase 3
Study type: Interventional

RATIONALE: Giving chemotherapy before a donor peripheral stem cell transplant or bone marrow transplant using stem cells from a brother or sister that closely match the patient's stem cells, 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. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal 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 colony-stimulating factors, such as G-CSF, to the donor helps the stem cells move from the bone marrow to the blood so they can be collected and stored. Giving methotrexate and cyclosporine before and after transplant may stop this from happening. It is not yet known whether a donor peripheral stem cell transplant is more effective than a donor bone marrow transplant in treating hematologic cancers or other diseases. PURPOSE: This randomized phase III trial is studying filgrastim-mobilized sibling donor peripheral stem cell transplant to see how well it works compared with sibling donor bone marrow transplant in treating patients with hematologic cancers or other diseases.

NCT ID: NCT00433745 Completed - Clinical trials for Myelodysplastic Syndrome

Wilm's Tumor 1 (WT1) Peptide Vaccine for High Risk Hematologic Malignancy

Start date: February 2007
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT00426205 Completed - Clinical trials for Refractory Acute Myeloid Leukemia

GM-CSF Vaccinations After Allogeneic Blood Stem Cell Transplantation in Patients With Advanced Myeloid Malignancies

Start date: June 2004
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00425477 Completed - Leukemia Clinical Trials

Bexarotene and GM-CSF in Treating Patients With Myelodysplastic Syndrome or Acute Myeloid Leukemia

Start date: November 2006
Phase: Phase 2
Study type: Interventional

RATIONALE: Bexarotene may help cancer or abnormal cells become more like normal cells, and to grow and spread more slowly. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving bexarotene together with GM-CSF may be an effective treatment for myelodysplastic syndrome (MDS) or acute myeloid leukemia. PURPOSE: This phase II trial is studying how well giving bexarotene together with GM-CSF works in treating patients with MDS or acute myeloid leukemia.

NCT ID: NCT00424242 Completed - Lymphoma Clinical Trials

Pemetrexed Disodium in the Cerebrospinal Fluid of Patients With Leptomeningeal Metastases

Start date: January 2007
Phase: Early Phase 1
Study type: Interventional

RATIONALE: Pemetrexed disodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Studying samples of cerebrospinal fluid and blood from patients with cancer in the laboratory may help doctors learn how pemetrexed disodium works in the body and identify biomarkers related to cancer. PURPOSE: This clinical trial is studying the side effects and how well pemetrexed disodium works in treating patients with leptomeningeal metastases.

NCT ID: NCT00423514 Completed - Leukemia Clinical Trials

Clofarabine, Melphalan, and Thiotepa Followed By a Donor Stem Cell Transplant in Treating Patients With High-Risk and/or Advanced Hematologic Cancer or Other Disease

Start date: November 20, 2006
Phase: Phase 1/Phase 2
Study type: Interventional

RATIONALE: Giving chemotherapy, such as clofarabine, melphalan, and thiotepa, before a donor stem cell 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 also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil before the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects and best dose of clofarabine when given together with melphalan and thiotepa, followed by a donor stem cell transplant and to see how well it works in treating patients with high-risk and/or advanced hematologic cancer or other disease.
