There are about 9403 clinical studies being (or have been) conducted in Switzerland. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
To compare the sequential administration of exemestane with administration of further tamoxifen until 5 years in postmenopausal women with operable breast cancer who have already received 2-3 years of adjuvant tamoxifen, in terms of disease-free survival (DFS), overall survival (OS), incidence of contralateral breast cancer and long-term tolerability.
This study is being done to evaluate the safety and efficacy of atrasentan in men with metastatic hormone-refractory prostate cancer.
The purposes of this study are to determine: 1. If treatment with LY900003 plus gemcitabine and cisplatin can help you live longer, compared with gemcitabine and cisplatin alone. 2. The safety of LY900003 plus gemcitabine and cisplatin and any side effects that might be associated with the combination of these three drugs. 3. Whether LY900003 plus gemcitabine and cisplatin can make your tumor smaller or disappear, and for how long, compared with gemcitabine and cisplatin alone. It is possible that information collected during this study will be analyzed by the sponsor in the future to evaluate LY900003 plus gemcitabine and cisplatin for other possible uses or for other medical or scientific purposes other than those currently proposed. LY900003 may not add any benefit to gemcitabine plus cisplatin.
RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Hormone therapy using exemestane plus bicalutamide may fight prostate cancer by reducing the production of androgens. It is not yet known if exemestane is more effective with or without bicalutamide in treating prostate cancer. PURPOSE: Randomized phase II trial to study the effectiveness of exemestane with or without bicalutamide in treating patients who have stage IV prostate cancer that has been previously treated with hormone therapy or surgery.
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/II trial to determine the effectiveness of combining capecitabine and paclitaxel in treating patients who have metastatic breast cancer.
RATIONALE: Hydroxychloroquine may decrease the immune response and be effective in treating chronic graft-versus-host disease. It is not yet known if standard therapy for graft-versus-host disease is more effective with or without hydroxychloroquine. PURPOSE: Randomized phase III trial to compare the effectiveness of standard therapy alone with that of standard therapy plus hydroxychloroquine in treating patients who have newly diagnosed chronic graft-versus-host disease.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high energy x-rays to damage tumor cells. Combining chemotherapy with radiation therapy before surgery may shrink the tumor so that it can be removed during surgery. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by radiation therapy before surgery in treating patients who have stage IIIB non-small cell lung cancer.
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: Randomized phase II trial to study the effectiveness of combination chemotherapy in treating patients who have advanced or metastatic colorectal cancer.
RATIONALE: Drugs used in chemotherapy, such as docetaxel and cisplatin, use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Giving chemotherapy with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. It is not yet known if chemotherapy plus radiation therapy is more effective than chemotherapy alone before surgery in treating non-small cell lung cancer. PURPOSE: This randomized phase III trial is studying docetaxel and cisplatin with or without radiation therapy to see how well they work when given before surgery in treating patients with stage IIIA non-small cell lung cancer that has spread to lymph nodes in the chest.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy drugs before surgery may shrink the tumor so that it can be removed during surgery. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have mesothelioma of the lung.
