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 determine if implementing a policy of widespread INH (Isoniazid) prophylaxis therapy in HIV-infected patients with access to antiretroviral therapy reduces the incidence of active TB disease in the HIV clinic population.
Hepatitis B is a contagious virus that can damage a person's liver. It can be prevented by vaccination, but for many HIV-positive people, the vaccines do not help them achieve adequate protection against this virus. In an attempt to improve response to vaccination and achieve protection from hepatitis B, this trial will compare the immune system response to 3 hepatitis B vaccine regimens in HIV-positive adolescents 12 through 24 years of age.
The purpose of this study is to compare Muraglitazar and Pioglitazone in patients with Type 2 Diabetes. Both the safety and blood sugar lowering effects of these treatments will be studied.
This 2 arm study will compare the safety and efficacy, with regard to reduction of signs and symptoms, of tocilizumab versus placebo in combination with traditional Disease-Modifying Anti-Rheumatic Drug (DMARD) therapy in patients with moderate to severe active rheumatoid arthritis (RA) who have had an inadequate response to current DMARD therapy. Patients will be randomized to receive tocilizumab 8mg/kg iv or placebo iv every 4 weeks, in conjunction with stable DMARD therapy. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
This 3 arm study will compare the safety and efficacy, with regard to reduction of signs and symptoms, of tocilizumab versus placebo, both in combination with methotrexate (MTX). in patients with moderate to severe active rheumatoid arthritis (RA) who currently have an inadequate response to MTX. Patients wil be randomized to receive tocilizumab 4mg/kg iv, tocilizumab 8mg/mg iv, or placebo iv, every 4 weeks; all patients will also receive methotrexate 10-25mg weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
This 3 arm study will compare the safety and efficacy, with respect to a reduction in signs and symptoms and prevention of joint damage, of tocilizumab versus placebo, both in combination with methotrexate (MTX) in patients with moderate to severe active rheumatoid arthritis. Patients will be randomized to receive tocilizumab 4 mg/kg IV, tocilizumab 8 mg/kg IV or placebo IV, every 4 weeks. All patients will also receive methotrexate, 10-25 mg/week. The anticipated time on study treatment is 1-2 years and the target sample size is 500+ individuals. After completion of the 2 year study participants could participate in the optional 3 year open label extension phase (year 3 to 5).
The purpose of the study is: Find out if patients receiving sorafenib will live longer. Find out if sorafenib has any effect on patient reported outcomes. Find out if sorafenib prevents the growth of or shrinks liver tumors and/or their metastases. Determine the pharmacokinetics (PK) in patients with liver cancer.
The purpose of the study is to determine the safety and effectiveness of two dose levels of micafungin versus caspofungin in the treatment of proven invasive candidiasis or candidemia.
This study is being conducted to compare the efficacy and safety of LAMICTAL (lamotrigine) extended-release with placebo in the treatment of Primary Generalized Tonic-Clonic (PGTC) seizures. LAMICTAL extended-release is an investigational drug. Placebo tablets look like LAMICTAL extended-release tablets but do not contain active medication. In this study, LAMICTAL extended-release or placebo tablets will be added to current seizure treatments.
The primary purpose of this study is to estimate the major cytogenetic response rates of BMS-354825 and imatinib (800 mg/d) in subjects with chronic phase, Philadelphia chromosome positive, chronic myeloid leukemia (PH+ CML) with disease resistant to imatinib at a dose of 400-600 mg/d.
