There are about 1129 clinical studies being (or have been) conducted in Estonia. 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.
This study is being conducted to evaluate the effectiveness and safety of LAMICTAL added to the current therapy of pediatric patients age 1-24 months old with partial seizures. The medication used in this study has been approved by FDA for the adjunctive treatment of partial seizures in patients 2 years and older.
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.
The purpose of this study is to compare two ways of using anti-HIV drugs to help health care providers and patients decide how to best use anti-HIV treatments over many years. Many health care providers now treat patients with daily drugs to keep the viral load as low as possible. This approach helps patients with CD4 counts less than 200-250 cells/mm3 live longer without serious diseases. But it is not known if this is the best way to treat patients with higher CD4 counts. There is information suggesting that these patients may be able to wait to use anti-HIV drugs while CD4 counts are above 250 cells/mm3. Because this study will be carried out over several years, it will provide information on the long-term advantages and disadvantages of these two treatment strategies.
Primary objective: - Compare disease-free survival in women with HER2-neu-expressing node-positive or high-risk node-negative operable breast cancer treated with adjuvant doxorubicin, cyclophosphamide, and docetaxel with or without trastuzumab (Herceptin) vs trastuzumab, docetaxel, and carboplatin. Secondary objective: - Compare overall survival of patients treated with these regimens. - Compare the toxic effects (including cardiac) of these regimens in these patients. - Compare quality of life of patients treated with these regimens. - Compare pathologic and molecular markers for predicting efficacy of these regimens in these patients. - For substudy: Compare peripheral levels of shed HER2-neu extracellular domain with fluorescence in situ hybridization in predicting outcome in patients treated with these regimens.
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: 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: Interleukin-2 may stimulate a person's white blood cells to kill acute myeloid leukemia cells. Histamine dihydrochloride may prolong remission and reduce the risk of relapse in patients with acute myeloid leukemia in remission. PURPOSE: Randomized phase III trial to determine the effectiveness of interleukin-2 plus histamine dihydrochloride in treating patients who have acute myeloid leukemia that is in remission following previous therapy.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining surgery with chemotherapy may kill more tumor cells. It is not yet known which treatment regimen is more effective for breast cancer. PURPOSE: Randomized phase III trial to study the effectiveness of chemotherapy plus surgery in treating women who have breast cancer.
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.
