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.
RATIONALE: Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known whether trastuzumab is effective in treating primary breast cancer in women who have completed adjuvant chemotherapy. PURPOSE: This randomized phase III trial is studying two different regimens of trastuzumab and observation only to compare how well they work in treating women with breast cancer.
RATIONALE: Decitabine may help myelodysplasia cells develop into normal stem cells. It is not yet known if decitabine is more effective than standard supportive care in treating myelodysplastic syndrome. PURPOSE: Randomized phase III trial to compare the effectiveness of low-dose decitabine with that of standard supportive care in treating older patients who have myelodysplastic syndrome.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplant may allow the doctors to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known which combination chemotherapy regimen given before peripheral stem cell transplant is more effective in treating relapsed Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is comparing different regimens of combination chemotherapy followed by peripheral stem cell transplant to see how well they work in treating patients with relapsed Hodgkin's lymphoma.
RATIONALE: Giving chemotherapy, such as hydroxyurea, cytarabine, idarubicin, and etoposide before a donor bone marrow transplant or stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. Interferon alfa may interfere with the growth of cancer cells and slow the growth of cancer. 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. It is not yet known whether chemotherapy is more effective with or without interferon alfa and/or bone marrow or stem cell transplant in treating patients with chronic myelogenous leukemia. PURPOSE: This randomized phase III trial is studying chemotherapy and biological therapy to see how well it works compared with chemotherapy, biological therapy, and donor bone marrow transplant or autologous stem cell transplant in treating patients with chronic phase chronic myelogenous leukemia.
This randomized, phase III trial was designed to test the efficacy of a low-dose chemotherapy-maintenance regimen, hypothesized to have anti-angiogenic activity, administered following standard chemotherapy in patients with early breast cancer whose tumors are hormone receptor negative.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy with peripheral stem cell transplant or bone marrow transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. It is not yet known whether high-dose chemotherapy plus peripheral stem cell or bone marrow transplant is more effective than chemotherapy alone in treating small cell lung cancer. PURPOSE: This randomized phase III trial is studying how well chemotherapy followed by peripheral stem cell or bone marrow transplant works compared to chemotherapy alone in treating patients with limited-stage or extensive-stage small cell lung cancer.
RATIONALE: Interferon alfa may interfere with the growth of the cancer cells. It is not yet known if this treatment is more effective than observation following surgery for stage III melanoma. PURPOSE: Randomized phase III trial to determine the effectiveness of interferon alfa in treating patients who have undergone surgery for stage III melanoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Combining chemotherapy with radiation therapy may kill more cancer cells. It is not yet known which combination chemotherapy regimen is most effective in treating Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of combination chemotherapy with or without radiation therapy in treating patients who have Hodgkin's lymphoma.
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. It is not yet known whether vaccine therapy is more effective than observation alone for melanoma. PURPOSE: This randomized phase III trial is studying vaccine therapy to see how well it works compared to observation alone in treating patients with primary stage II melanoma.
RATIONALE: Amifostine may improve blood counts in patients with myelodysplastic syndrome. Epoetin alfa may stimulate red blood cell production and be an effective treatment for anemia in patients with myelodysplastic syndrome. PURPOSE: Phase II trial to study the effectiveness of amifostine with or without epoetin alfa in treating patients who have myelodysplastic syndrome.
