There are about 10004 clinical studies being (or have been) conducted in Brazil. 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 it is effective to give HIV positive patients recombinant interleukin-2 (rIL-2) in addition to anti-HIV therapy. Patients will be followed over a minimum of 4 years to study the long-term effects of rIL-2 on their HIV disease progression. Anti-HIV therapy has been very successful in treating HIV positive patients and in keeping viral load (level of HIV in the blood) low. However, anti-HIV drugs cannot completely rid the body of the virus, and the immune system is never completely restored in HIV positive patients. Doctors hope that giving patients recombinant interleukin-2 (rIL-2) in addition to their anti-HIV therapy will help improve their immune systems and keep them healthier over a longer period of time. rIL-2 is a hormone naturally produced by the body during an immune response to a microbial infection.
The purpose of this study is to look at the safety and effectiveness of receiving lamivudine (3TC) once a day versus twice a day as part of an anti-HIV drug combination.
Compare the outcome of two primary surgeries techniques (von Langenbeck and Furlow double z-plasty) performed on children with cleft lip/palate to determine if one results in significantly better velopharyngeal competency for speech.
The purpose of this study is to see how safe a new protease inhibitor (PI) is and how well it fights HIV infection. A PI is a drug that stops HIV from using healthy cells to make more virus. This study will compare the new PI combination of ABT-378 plus ritonavir (RTV) with another PI, nelfinavir (NFV). Earlier studies suggest ABT-378/RTV will be just as good as and perhaps better than NFV at fighting HIV infection.
The purpose of this study is to compare the safety and effectiveness of 2 anti-HIV drug combinations in HIV-infected patients. Both combinations will include nevirapine (NVP), 2 nucleoside reverse transcriptase inhibitors (NRTIs), and at least 1 protease inhibitor (PI). One combination will include a new protease inhibitor, ABT-378, combined in a capsule with ritonavir (RTV).
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 fluorouracil given as a continuous infusion in treating patients with recurrent or metastatic bladder cancer.
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. It is not yet known whether chemotherapy is more effective than radiation therapy for testicular cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of carboplatin with that of radiation therapy in treating patients who have stage I testicular cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if combination chemotherapy given after surgery is more effective than surgery alone for non-small cell lung cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy following surgery with that of surgery alone in treating patients who have stage I, stage II, or stage IIIA non-small cell lung cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective for intermediate-grade or immunoblastic non-Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of two combination chemotherapy regimens in treating patients who have intermediate-grade or immunoblastic non-Hodgkin's lymphoma.
To compare the effect of AS-101 to that of placebo on clinical efficacy and immunologic function in HIV positive patients with advanced disease. To compare the effect of AS-101 to that of placebo on occurrence of disease progression in HIV positive patients with advanced disease as defined by: (1) development of new diagnostically confirmed major opportunistic infection(s); or (2) development of AIDS-related dementia. To compare the effect of zidovudine (AZT) plus AS-101 versus AZT alone (placebo arm) on clinical efficacy and immunologic function in patients who require anti-viral therapy due to disease progression. Garlic capsules will be given to all study participants to mask the obvious garlic odor of AS-101.
