Filter by:This study will evaluate the safety and effectiveness of stem cell transplantation in which the donor's T cells (a type of lymphocyte, or white blood cell) are removed and then added back. Certain patients with bone marrow malignancies undergo transplantation of donated stem cells to generate new and normally functioning bone marrow. However, T-cells from the donor may see the patient's cells as foreign and mount an immune response to reject them, causing what is called "graft-versus-host-disease" (GVHD). Therefore, in this protocol, T-cells are removed from the donor cells to prevent this complication. However, because T-cells are important in fighting viral infections as well as any remaining malignant cells (called graft-versus-leukemia effect), the donor T-cells are given to the patient (added back) at a later time after the transplant when they can provide needed immunity with less risk of causing GVHD. Patients between 10 and 55 years of age with acute or chronic leukemia, myelodysplastic syndrome, or myeloproliferative syndrome may be eligible for this study. Prospective participants and their donors are screened with a medical history and physical examination, blood tests (including a test to match for genetic compatibility), breathing tests, chest and sinus x-rays, and tests of heart function. They also undergo a bone marrow biopsy and aspiration. For this procedure, done under local anesthetic, about a tablespoon of bone marrow is withdrawn through a needle inserted into the hipbone. They undergo apheresis to collect lymphocytes for research studies. This procedure involves collecting blood through a needle in the arm, similar to donating a unit of blood. The lymphocytes are then separated and removed by a cell separator machine, and the rest of the blood is returned through a needle in the other arm. Before treatment begins, patients have a central intravenous line (flexible plastic tube) placed in a vein in the chest. This line remains in place during the stem cell transplant and recovery period for drawing and transfusing blood, giving medications, and infusing the donated cells. Preparation for the transfusion includes high-dose radiation and chemotherapy. Patients undergo total body irradiation in 8 doses given in two 30-minute sessions a day for 4 days. Eight days before the transplant, they begin taking fludarabine, and 3 days before the procedure they start cyclophosphamide.
This phase I/II trial studies whether stopping cyclosporine before mycophenolate mofetil is better at reducing the risk of life-threatening graft-versus-host disease (GVHD) than the previous approach where mycophenolate mofetil was stopped before cyclosporine. The other reason this study is being done because at the present time there are no curative therapies known outside of stem cell transplantation for these types of cancer. Because of age or underlying health status, patients may have a higher likelihood of experiencing harm from a conventional blood stem cell transplant. This study tests whether this new blood stem cell transplant method can be made safer by changing the order and length of time that immune suppressing drugs are given after transplant.
This is a first-in-man, open-label, non-randomized, multiple dose, multiple cycle, dose escalation study to determine the MTD, safety, PK, and pharmacodynamics of E7820 in patients with a malignant solid tumor or lymphoma.
Phase 2B, multicenter study evaluating the safety and efficacy of weekly TOCOSOL Paclitaxel in taxane-naive patients receiving second line chemotherapy for metastatic or locally advanced, unresectable transitional cell carcinoma of the urothelium
This phase I trial is studying the side effects and best dose of erlotinib when given with temozolomide in treating young patients with recurrent or refractory solid tumors. Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving erlotinib with temozolomide may kill more tumor cells.
The purpose of this study is to demonstrate improvement in overall survival for the combination of whole brain radiation therapy (WBRT) plus temozolomide (TMZ) versus WBRT alone. Secondary objective is to demonstrate an improvement in the time to radiological CNS progression with the addition of TMZ to WBRT.
This randomized phase III trial is studying total-body irradiation (TBI) and fludarabine phosphate to see how it works compared with TBI alone followed by donor stem cell transplant in treating patients with hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and radiation therapy before a donor 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. The donated stem cells may replace the patient's immune system 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 cyclosporine and mycophenolate mofetil after transplant may stop this from happening. It is not yet known whether TBI followed by donor stem cell transplant is more effective with or without fludarabine phosphate in treating hematologic cancer.
This phase II trial is studying how well gefitinib works in treating patients with progressive metastatic neuroendocrine tumors. Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth.
This study will compare the effectiveness of craniotomy to that of stereotactic surgery (SRS) for the treatment of metastatic brain tumors - tumors that first develop elsewhere in the body and then travel to the brain. Craniotomy is surgical removal of the tumors through an operation. SRS consists of highly focused radiation doses to the tumors. Neither treatment is experimental and both have shown benefits to patients with metastatic brain tumors. This study will determine whether one treatment is superior to the other in prolonging patient survival. Patients 21 years of age and older with one to three metastatic brain tumors may be eligible for this study. Participants will have a medical history and physical examination, blood and urine tests, an electrocardiogram, and chest x-ray. They will then be randomly assigned to undergo either surgery or SRS. Before either procedure, patients will have a magnetic resonance imaging (MRI) scan. MRI uses a strong magnetic field and radio waves to obtain images of the brain. Patients scheduled for SRS will have a computed tomography (CT) scan in addition to the MRI. CT uses X-rays to obtain images of the brain. During the CT, a contrast agent is injected through an IV tube placed in a vein to enhance the CT images. For both the MRI and CT tests, the patient lies on a table that slides into a cylindrical scanner. The MRI usually lasts between 45 and 90 minutes, while the CT scan lasts for about 30 to 60 minutes. Patients scheduled for surgery will have general anesthesia or local anesthesia with sedation. They will be in intensive care after the surgery until their condition is stable. Before being discharged home, they will have another MRI scan. The surgical sutures or staples will be removed 7 to 10 days after surgery. Patients scheduled for SRS will have their scalp numbed with medicine and their head will be placed in a head frame. A CT scan will be done on the morning of the procedure to plan the treatment. Around noon, the treatment, which consists of brief exposures to radiation, will be administered with the patient positioned comfortably on a treatment couch. The treatment will be completed in 1 to 2 hours, after which the head frame will be removed. After a brief period of observation, the patient will be discharged home. Patients will return to NIH for follow-up visits within 4 weeks after surgery or SRS and then every 3 months after that for a medical history, physical examination, and MRI scan, and to complete a quality of life questionnaire.
The purpose of this study is to determine whether CP-547,632, an oral VEGFR-2 tyrosine kinase inhibitor is effective in the treatment of epithelial ovarian cancer, primary peritoneal serous cancer, or fallopian tube cancer for patients who have failed first line platinum-based therapy and have a persistent rising CA-125.
