Filter by:The purpose of this clinical trial is to establish the safest doses for the combination of a farnesyl transferase inhibitor, R115777 plus topotecan in patients with advanced solid tumors, previously treated or beyond standard therapy of clinical benefit. Maximum tolerated dose, dose limiting toxicity and the activity of this combination will be assessed. This chemotherapy regimen is a two-pronged attack at the way cancer cells replicate. R115777 is a compound that may inhibit cancer cell growth by interfering with the p21 ras oncogene, while topotecan, a topoisomerase-1 inhibitor, works on cancer cells not subject to control by the ras oncogene. Animal studies suggest that the combination may be synergistic. Another advantage is that R115777 can be taken by mouth.
Promoting Healthy Lifestyles: Alternative Models' Effects (PHLAME) is a research study to evaluate and compare two ways to promote healthy behaviors, (regular physical activity, less than 30% calories from fat, 5 or more servings of fruits plus vegetables each day and maintain a healthy weight). Unhealthy nutrition practices and sedentary (inactive) lifestyles are the two most common harmful behaviors in the United States. Our two health promotion methods are 1) a team-based approach and 2) a one-on-one approach involving meetings with a health counselor. A third group only receives the same evaluation and their results and is the control group. Study participants are firefighters from 36 fire stations in Oregon and Washington. The goals of the study are increased physical activity and fitness, improved nutrition, and improved energy balance (reduced body fat). Changes in these factors can help lower risks for heart disease, some types of cancer, diabetes, hypertension and musculoskeletal injuries. Results from PHLAME will provide information on how best to help adults achieve and maintain healthy lifestyles.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of oxaliplatin with or without floxuridine and leucovorin in treating patients who have metastatic cancer of the peritoneum.
Phase I trial to study the effectiveness of trastuzumab plus R115777 in treating patients who have advanced or metastatic cancer. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining trastuzumab with R115777 may kill more tumor cells.
This study will examine the safety and toxicities of intravenously administering a genetically modified type of Salmonella bacteria (VNP20009) and its impact on tumor growth in advanced or metastatic cancer (cancer that has spread from the primary site). The first patients in the study will be given the smallest dose of VNP20009, and those who enter later will receive increasingly larger doses. This will be done to determine the maximum dose that can be given without serious side effects. Normally, Salmonella bacteria ingested in food or water can cause diarrhea or more severe illness. The bacteria in this study are altered genetically so they can be injected through a vein and circulate in the blood with less likelihood of causing side effects. It is believed that the bacteria will travel in the blood to the tumor and infect it. In studies of mice, tumor growth slowed in animals whose tumors were infected with VNP0009. Patients with advanced or metastatic cancer 18 years of age or older whose disease is not responding to standard treatment, or for which there is no treatment, may be eligible for this study. Candidates will undergo a medical history and physical examination, including blood tests, scans, X-rays, electrocardiogram, and urine, stool and blood cultures. Study participants will be admitted to the hospital for 2 to 4 days. On day 1, they will receive the first dose of VNP0009, infused over a 30-minute period through an intravenous catheter (a small plastic tube inserted into a vein). Blood will be drawn every day to determine if the bacteria are still in the body. After discharge, patients will return to the hospital on days after approximately 1-2 weeks and again after 4-5 weeks for additional blood tests to measure levels of the bacteria and for collection of blood, urine and stool samples. Patients whose tumors are on or just beneath the skin may be asked to have one or two tumors removed surgically. Patients will have tests after approximately 4-5 weeks, including CTs and X-rays, to determine the size and extent of the tumor. Patients whose tumor remained the same size or smaller than before starting treatment, and whose side effects were acceptable will be offered a second treatment cycle. Those whose tumor grew during treatment will be taken off the study. Patients remaining in the study will begin the second cycle on approximately day 36. Tumor growth will be evaluated again between days 64 and 70, and a third cycle will be offered to patients whose tumors have remained stable or have shrunk. Patients may have up to 12 treatment cycles as long as evaluations continue to show the tumor is stable or shrinking. Completing all 12 cycles takes about 13 months. Patients will continue to be evaluated after treatment ends, if they agree to continued follow-up. Patients must follow health precautions to prevent infecting others with Salmonella bacteria as long as they, themselves, remain infected. These include, for example, stringent hand washing practices and avoiding contact with people with weakened immune systems. All the precautions will be explained to the study participants. Patients who leave the study must take antibiotic therapy to rid the body of any remaining bacteria. They will return for urine, stool and blood cultures 30 days after the start of antibiotics, and may undergo three types of scans to look for sites of infection. Treatment will be given as needed.
RATIONALE: Captopril may protect the lungs from the side effects of bone marrow or stem cell transplantation. PURPOSE: Randomized phase III trial to determine the effectiveness of captopril to lessen the side effects in patients who are undergoing bone marrow or stem cell transplantation following chemotherapy and radiation therapy.
RATIONALE: Inserting a gene that has been created in the laboratory into a person's white blood cells may make the body build an immune response to kill cancer cells. PURPOSE: Phase I trial to study the effectiveness of gene therapy in treating patients who have cancer that has not responded to previous therapy.
RATIONALE: Liposomal amphotericin B may be effective in controlling fever and granulocytopenia. It is not yet known which regimen of liposomal amphotericin B is more effective in treating cancer patients who have these conditions. PURPOSE: Randomized phase III trial to compare the effectiveness of two regimens of liposomal amphotericin B in treating granulocytopenia and fever in cancer patients.
RATIONALE: Giving itraconazole or fluconazole may be effective in preventing infections in patients undergoing peripheral stem cell or bone marrow transplantation. It is not yet known whether itraconazole is more effective than fluconazole for preventing infections. PURPOSE: Randomized phase III trial to compare the effectiveness of itraconazole with fluconazole to prevent infections in patients undergoing peripheral stem cell or bone marrow transplantation.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of irinotecan and capecitabine in treating patients who have solid tumors that have not responded to previous treatment.
