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.
Prospective, multicentric, single-arm study to evaluate fast and effective tissue repair in patients undergone percutaneous coronary intervention with drug eluting stent Inspiron.
The purpose of this study is to determine whether the combination of pevonedistat and azacitidine improves event-free survival (EFS) when compared with single-agent azacitidine. (An event is defined as death or transformation to AML in participants with MDS or CMML, whichever occurs first, and is defined as death in participants with low-blast AML).
Two-center randomized, parallel, controlled trial which will compare a pragmatic combined training program with a health education program in 184 older adults with hypertension. This study will last 12 weeks with assessments conducted at baseline, previously to the group allocation, and after interventions. There is a set of secondary outcomes which show clinical importance to the elderly population and are possibly influenced by the tested intervention.
The purpose of this study is to evaluate the efficacy and safety of dTMS used as a tool for the smoking cessation; therefore, the subjects will be randomized to be treated on the active group or to receive placebo stimulation.
The aim of this study is to evaluate the additional effect of antimicrobial photodynamic therapy regeneration treatment of mandibular furcation lesions when associated to bovine bone and porcine collagen membrane.
The objective of this randomized clinical trial is to compare pain levels during and after insufflation with carbon dioxide or in subjects that will undergo endoscopic fulguration with argon to reduce the diameter of the gastrojejunal anastomosis. The investigators hypothesize that carbon dioxide will be superior in causing less pain and leading to less discomfort.
Compare the use of nandrolone associated with corticosteroid for the treatment of cancer-induced malnutrition to treatment with corticosteroids alone in patients with tumors in the high gastro-intestinal tract, liver, pancreas and bile ducts in palliative treatment.
Post-marketing, prospective, multicentric, non-randomized registry to evaluate the safety and efficacy of Inspiron Sirolimus Eluting Coronary Stent at the treatment of "real-world" patients.
The current project aims to investigate the efficacy of the visual imaging training (VIT) and alphabet search training in comparison to an active control intervention, namely psychoeducation information (PI) using fMRI in patients with amnestic mild cognitive impairment (MCI) and healthy elderly controls (HE). MCI patients will be grouped according to biomarkers (PET PIB, PET FDG and liquor).
The purpose of this study is to compare the incidence of Zika virus (ZIKV) infection among pregnant women with and without Human Immunodeficiency Virus (HIV) infection and to determine the risk of adverse maternal and child outcomes associated with ZIKV/HIV co-infection across clinical sites in the continental United States (U.S.), Puerto Rico (P.R.) and Brazil.
