Filter by:The purpose of this clinical research study is to learn if vinflunine can shrink or slow the growth of the cancer or increase survival in patients with transitional cell carcinoma of the urothelium. The safety of this treatment will also be studied.
This phase I trial is studying the side effects and best dose of oxaliplatin when given together with irinotecan in treating young patients with refractory solid tumors or lymphomas. Drugs used in chemotherapy, such as oxaliplatin and irinotecan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Oxaliplatin may help irinotecan kill more cancer cells by making cancer cells more sensitive to the drug. Giving oxaliplatin together with irinotecan may kill more cancer cells.
This phase I trial is studying the side effects and best dose of lenalidomide in treating young patients with recurrent, progressive, or refractory CNS tumors. Lenalidomide may stop the growth of CNS tumors by blocking blood flow to the tumor. It may also stimulate the immune system in different ways and stop tumor cells from growing.
This phase II trial is studying how well giving radiation therapy together with temozolomide and lomustine works in treating young patients with newly diagnosed gliomas. Radiation therapy uses high energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide and lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with temozolomide and lomustine after surgery may kill any remaining tumor cells.
The primary purpose of this study is to identify a dose of Liposome Entrapped c-raf Antisense Oligonucleotide Easy-to-Use (LErafAON-ETU) which maximizes potential benefits of the compound to patients with advanced cancer, without compromising their safety. This study will also assess the processing of LErafAON-ETU by the body over time. Patients will receive an intravenous infusion of LErafAON-ETU each week. Multiple blood samples will be taken for pharmacokinetic analysis during the first treatment; two samples will be taken during both the second and third treatments. Patients will be eligible to continue treatment until the occurrence of unacceptable toxicity or disease progression. In LErafAON-ETU, antisense oligonucleotides specific to c-raf, are associated with liposomes, which are microscopic membrane-like structures created from lipids (fats). Raf-1 is a protein which plays a critical role in many aspects of cellular activation and growth. Therefore, it is thought to be an important factor that may support tumor development. LErafAON-ETU potentially limits the ability of a cell to produce the Raf-1 protein.
This study will use a procedure called selective venous catheterization in patients with tumor-induced osteomalacia (TIO) or oncogenic osteomalacia (OOM) to try to locate very small tumors that produce proteins called phosphatonins. Too much phosphatonin in the blood causes the kidneys to allow large amounts of phosphorus to be excreted in the urine, leading to low blood levels of phosphorus and, in turn, to osteomalacia (a condition of soft bones). Osteomalacia can cause bone fractures requiring many surgical procedures that can leave patients in pain. Patients may also feel weak and can lose height from massive bone loss. Selective venous catheterization is a way to measure the amount of phosphatonin in the blood and may be used as a way to locate phosphatonin-producing tumors that cannot be found using standard imaging techniques. Patients with TIO or OOM are screened under NIDR Protocol 01-D-0184 with a medical history, review of medical records and routine physical examination. Other procedures may include blood tests, urine tests, and imaging tests, such as x-rays, bone densitometry, bone scan, computed tomography (CT) and magnetic resonance imaging (MRI). This study will include mostly patients whose tumors were not able to be located through imaging procedures, but also a few patients whose tumors were located. All participants, regardless of whether or not their tumor was located, undergo selective venous catheterization. For this procedure, a radiologist inserts a catheter (thin flexible tube) into the body and uses fluoroscopy (a type of x-ray) to guide the tip of the catheter to different places in the body to collect small amounts of blood from the different areas. After the procedure, the patient lies flat for 2 hours and avoids moving his or her leg on the side where the catheter was placed. The blood is analyzed to measure the amount phosphatonin is in each sample, and the amounts are compared to the average amount of phosphatonin in the general blood circulation. If a higher level of phosphatonin is found in one area and the location of the tumor is unknown, the patient undergoes imaging in that area. If a tumor is found and it is in an area where it can be removed surgically, the patient is given the option to have the surgery. If the tumor is not found by imaging done after the first catheterization procedure, the patient has the option to have a second catheterization, taking samples of blood only from the area where the phosphatonin was found to be the highest during the sampling procedure.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, effect of food, and continue exploratory research of BMS-354825 in patients with solid tumors not responding to standard treatment, or for which no effective standard treatment exists.
This study will explore what research patients understand about financial collaborations in the research setting and their concerns about these collaborations. Financial partnerships are crucial to advancing medical research; however, they are giving rise to increasing concerns about financial conflicts of interest and possible impacts on the integrity of research and patient safety. This study will examine patients' views about financial ties between drug companies and the doctors running research studies, as well as ties between the drug companies and the cancer centers where the studies are conducted. Patients 18 years of age and older who are enrolled in cancer studies at the National Cancer Institute in Bethesda, MD; the Fred Hutchinson Cancer Research Center in Seattle, WA; the Dana-Farber Cancer Institute in Boston, MA; the Columbia Comprehensive University Herbert Irving Cancer Center in New York, NY; and the University of Colorado Cancer Center in Denver, CO, may be eligible for this study. Participants are interviewed about the following: - Patients' awareness and understanding about individual and institutional financial conflicts of interest, and how such conflicts, if they exist, are being managed - The impact of a researcher's financial ties on the patient's decision to participate in that researcher's study - The impact of the institution's financial ties on the patient's decision to participate in research at that institution - Attitudes about policies and practices regarding conflicts of interest in the research setting - Attitudes about disclosure of conflicts of interest in the research setting - Patient symptoms and performance - Patient's cancer trial - Patient's cancer history - Patient's trust - Patient demographics (gender, age, race, religion, education, income, health insurance, employment).
Background: - BAY 43-9006 is an inhibitor of wild-type and mutant B-Raf and c-Raf kinase isoforms in vitro, but it also inhibits p38, c-kit, VEGFR-2 and PDGFR-Beta affecting tumor growth as well as possibly promoting apoptosis by events downstream of c-Raf. - Bevacizumab is a humanized IgG1 monoclonal antibody (MAb) that binds all biologically active isoforms of human vascular endothelial growth factor (VEGF, or VEGF-A) with high affinity (k(d)= 1.1nM) - The most common adverse events associated with bevacizumab of any severity include asthenia, pain, headache, hypertension, diarrhea, stomatitis, constipation, epistaxis, dyspnea, dermatitis and proteinuria. - This Phase I trial is open to patients with all solid tumors. Objectives: - Determine the safety and toxicity of the combination of BAY 43-9006 (Sorafenib) and bevacizumab. - Determine estimates of biochemical changes in the Ras-Raf-MAPK and VEGF signal transduction pathways in tumor and stromal cells in response to treatment at the MTD, at least in a pilot fashion, if those changes are statistically significant.
