There are about 173942 clinical studies being (or have been) conducted in United States. 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 see if the amount of stem cells (cells that can develop into many kinds of cells) in the blood before anti-HIV drugs are taken can predict if the immune system will become stronger after anti-HIV drugs are given and if anti-HIV drugs can restore stem cells. HIV infection has been shown to cause stem cells not to function well. Granulocyte colony-stimulating factor (G-CSF), which causes stem cells to go from the bone marrow (tissues in the bones where blood cells are formed) into the bloodstream, could possibly help boost immunity after anti-HIV treatment. This study examines the effects of G-CSF in helping the immune system become stronger after beginning anti-HIV treatment.
RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill cancer cells. PURPOSE: Randomized phase II/III trial to determine the effectiveness of bone marrow transplantation in treating patients who have leukemia.
The purpose of this study is to find out if anti-HIV drugs, taken by patients who are newly infected with HIV, can make the level of HIV in the body too low to detect. Studying patients who recently have been infected with HIV may help researchers understand how HIV infection works and how anti-HIV drugs may help these patients. Approved anti-HIV drugs can reduce the amount of HIV, but more research needs to be done in newly infected patients. This study will look at recently HIV-infected patients to study the progression of HIV disease and to see whether anti-HIV drugs can reduce the level of HIV.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known which regimen of radiation therapy may be more effective in preventing brain metastases. PURPOSE: Randomized phase III trial to study the effectiveness of radiation therapy in preventing brain metastases in patients who have small cell lung cancer that has been diagnosed within the past year.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of combining carboplatin, temozolomide, and filgrastim in treating patients who have newly diagnosed or recurrent high-grade glioma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. Donor lymphocytes may attack and destroy cancer cells. PURPOSE: This phase II trial is studying the effectiveness of combination chemotherapy, peripheral stem cell transplantation, and donor lymphocyte infusion in treating women with stage IV breast cancer.
RATIONALE: Chemotherapy uses different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase I/II trial to study the effectiveness of chemotherapy and peripheral stem cell transplantation followed by trastuzumab in treating women who have metastatic breast cancer.
RATIONALE: A specially modified virus called ONYX-015 may be able to kill tumor cells while leaving normal cells undamaged. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining ONYX-015 with chemotherapy may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of ONYX-015 combined with cisplatin and fluorouracil in treating patients who have advanced head and neck cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Randomized phase I trial to determine the effectiveness of genistein in treating patients who have stage II, stage III, or stage IV prostate cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of ILX-295501 in treating patients who have stage III or stage IV ovarian cancer that has not responded to previous therapy.
