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 investigators raised the hypothesis that exercise training would be associated with improvement in exercise tolerance and VO2 kinetics in hemodialysis patients.
This is a Phase 3 randomized, double blind, placebo controlled study of tasquinimod in asymptomatic to mildly symptomatic patients with metastatic CRPC to confirm the effect of tasquinimod on delaying disease progression compared with placebo. Approximately 1200 eligible patients with metastatic CRPC will be randomly assigned in a 2:1 ratio to 1 of 2 treatment groups: Treatment Group A (tasquinimod 0.25, 0.5, or 1 mg/day; n=800) or Treatment Group B (placebo; n=400).
The purpose of this study is to test the external validity of the systemic ultrasound protocol for data acquisition and interpretation, in order to diagnose soft tissue and osteochondral abnormalities in hemophilic children.
This randomized, parallel-group, placebo-controlled, multicenter study will evaluate the reduction in disease activity and the safety of tocilizumab (RoActemra/Actemra) in combination with traditional disease-modifying anti-rheumatic drugs (DMARDs) in patients with active, moderate to severe rheumatoid arthritis. In the double-blind part of the study, patients will be randomized to receive either 162 mg tocilizumab or placebo subcutaneously every 2 weeks for 24 weeks using a pre-filled syringe. In the open-label part of the study, patients will be randomized to receive 162 mg tocilizumab subcutaneously every 2 weeks from Week 24 to Week 96 using a pre-filled syringe or an auto-injector.
The primary purpose of this study is to evaluate the hypothesis that cixutumumab given in combination with cisplatin and pemetrexed is superior to cisplatin and pemetrexed as first-line therapy for patients with advanced nonsquamous non-small cell lung carcinoma (NSCLC).
The purpose of this study is to test the safety and efficacy of zanamivir given intravenously and how well it works at two different doses in hospitalized adolescents and adults with flu. Zanamivir will be compared with oseltamivir, which is used for treating flu.
ING111762 is a 48 week, randomized, double-blind, active-controlled, multicenter, parallel group, non-inferiority study. The study will be conducted in at least 688 HIV-1 infected antiretroviral experienced, integrase-naïve subjects. Subjects will be randomized 1:1 to receive GSK1349572 50 mg once daily or raltegravir (RAL) 400 mg twice daily, each added to an investigator selected background regimen consisting of at least one fully active agent plus no more than one second single agent which may or may not be active. Antiviral activity, safety, pharmacokinetics (PK), and development of viral resistance will be evaluated.
The aim of the present study was to evaluate the effects of anaesthesia with sevoflurane and surgery on cytokines response.
There is a controversy in the dentistry literature about how the use of associated light to activate 35% hydrogen peroxide gel during in-office tooth bleaching may increase the bleaching effectiveness. The studies that demonstrated an increased level of bleaching using light activation employed lower hydrogen peroxide gels while the ones reporting no statistical difference employed higher hydrogen peroxide gels. The hypothesis of this study is that the effectiveness of light activation tooth bleaching in dependent on the hydrogen peroxide concentration employed.
The purpose of this study is to evaluate the blood loss in induced vaginal delivery by misoprostol and caesarians section with induction attempt.
