There are about 6461 clinical studies being (or have been) conducted in Russian Federation. 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.
The purpose of this study is to provide evidence that the Refined Ventricular Pacing Algorithm leads to clinically relevant reduction (at least 50% reduction) of the incidence of ventricular pacing.
The purpose of this study is to assess the benefits and risks of treating very elderly (those aged 80 or older) individuals with hypertension.
The purpose of this study is to evaluate the efficacy of a new dose of 500 mg Fulvestrant with the standard dose of 250 mg in postmenopausal women with oestrogen receptor positive advanced breast cancer who have failed on a previous endocrine treatment.
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: Drugs used in chemotherapy such as docetaxel use different ways to stop tumor cells from dividing so they stop growing or die. Oblimersen may increase the effectiveness of docetaxel by making the tumor cells more sensitive to the drug. It is not yet known if docetaxel is more effective with or without oblimersen in treating non-small cell lung cancer. PURPOSE: Randomized phase II/III trial to compare the effectiveness of docetaxel with or without oblimersen in treating patients who have relapsed or refractory non-small cell lung cancer that has been previously treated.
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: Interferon alfa may interfere with the growth of cancer cells. It is not known whether giving high-dose or low-dose interferon alfa is more effective than no further therapy in treating patients with stage III melanoma. PURPOSE: Randomized phase III trial to compare the effectiveness of high- or low-dose interferon alfa with that of no further therapy following surgery in treating patients who have stage III melanoma.
