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 the study is to see if one plan for identifying and treating tuberculosis (TB) works better than another in reducing new cases of TB. The first plan is the DOTS program, which provides free TB treatment to people seeking it. The second plan provides free TB treatment to people seeking it and involves program staff going door-to-door in communities to identify new cases of TB, DOTS plus active case-finding program (ACF). Researchers believe that by detecting TB cases earlier and supervising treatment it will help to prevent spreading and decrease TB in these areas. The study population will be 200,000 people in 6 communities of Santa Cruz and 14 communities of Northeast Rio de Janeiro, Brazil, receiving DOTS or DOTS plus ACF. Individuals in the DOTS plus ACF part of the study will be interviewed 2-4 times during a 9 month period. Patients with symptoms will provide a sputum specimen. Patients identified as having TB will begin treatment and be observed for 6.
The purpose of this study is to follow the health of subjects who have previously been enrolled in studies of CP-690,550 for treatment of their rheumatoid arthritis. Subjects are only eligible for this study after they have completed all participation in other studies of CP-690,550.
The purpose of this study is to determine the long-term effectiveness and safety of CP-690,550 for the treatment of rheumatoid arthritis. Subjects are eligible for this study only after participating in another "qualifying" study of CP-690,550 A sub-study will be conducted within the A3921024 study, this study will evaluate the immune response to pneumococcal and influenza vaccines in patients receiving CP-690,550
The purpose of this study is to determine the effectiveness and safety, over 6 months, of 6 dose regimens of CP-690,550, combined with methotrexate, for the treatment of adults with active rheumatoid arthritis.
The purpose of the study is to compare the safety and efficacy of isavuconazole versus caspofungin followed by voriconazole in the treatment of candidemia and other invasive Candida infections.
The trial seeks to determine if apixaban, an investigational anticoagulant (blood-thinner) is as effective as standard therapy (warfarin) in preventing stroke and systemic embolism in subjects with atrial fibrillation and risk factors for stroke.
The purpose of this study is to compare the efficacy and safety of isavuconazole versus voriconazole in the treatment of patients with invasive aspergillosis.
This is a phase 3, randomized, multi-center study to evaluate the efficacy and safety of albumin interferon alfa-2b (alb-IFN)in combination with ribavirin compared with peginterferon alfa-2a (PEGASYS or PEG-IFNa2a) in combination with ribavirin in subjects with chronic hepatitis C, genotype 2/3 who are IFNa treatment naive.
To evaluate the efficacy and safety of three insulin algorithms in medical ICU patients (MICU).
The purpose of this clinical research study is to learn if abatacept can improve signs and symptoms of active ulcerative colitis in patients who have not had an adequate response to other therapies. The safety of this treatment will also be studied
