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 objective this study is evaluate the performance and safety of Chronus® cobalt-chromium coronary stent in patients with "de novo" native coronary artery lesions treated with 19-mm-long stents in long-term 9 months.
The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF Registry) is a non-interventional, observational study that characterized a global population of non-valvular atrial fibrillation patients. The registry was used to document global baseline characteristics, current treatment strategies and outcome measures. Characterisation of a number of AF sub-populations was also completed. GARFIELD-AF is an independent academic research initiative sponsored by the Thrombosis Research Institute (London, UK) and supported by an unrestricted research grant from Bayer AG (Berlin, Germany).
The aim of the study was to evaluate the effect of eccentric strength training for shoulder abductors on force steadiness in subjects with subacromial impingement syndrome (SIS).
Several studies have demonstrated the efficacy of asthma treatment but despite being correctly diagnosed, conveniently prescribed and adherent to the therapeutics, 5% to 10% of asthmatics do not reach disease control. The aim of this study is to measure asthma control, evaluate inflammatory and functional characteristics, describe comorbidities and aggravating factors and phenotypes derived from the characteristics of a severe asthmatic population followed at an outpatient university service in Sao Paolo, Brazil.
The primary objective of phase 1 of this study is to establish the recommended phase II dose (RP2D). The primary objective of phase 2 of this study is to evaluate the safety and efficacy of bendamustine at the recommended pediatric dose for the treatment of pediatric patients with relapsed or refractory acute leukemia.
Acute effects of CPAP on diastolic function in patients with compensated heart failure (CHF) are unknown. The investigators hypothesized that acutely CPAP improves diastolic function, which is associated with increases exercise tolerance. Objective: To evaluate the acute effects of CPAP on functional capacity and diastolic indices of patients with CHF. This is a randomized trial including 44 patients with compensated heart failure (functional classes II or III, NYHA). Patients will be allocated in CPAP(CPAP with 10cmH2O) or simulated CPAP (null pressure) after computed randomization, in a 1:1 ratio. All subjects shall complete a 6-minute walk test (6MWT) before and after CPAP (30 minutes; 10 cm H2O pressure). Doppler-echocardiogram will be performed before and at the end of CPAP. Wilcoxon or paired t tests were used to compare results, with significance level at p < 0.05.
Phase 3, multicenter, randomized, double-blind, parallel-group, placebo-controlled study to evaluate the efficacy and safety of Certolizumab Pegol (CZP) in subjects with adult onset active and progressive Psoriatic Arthritis (PsA).
The study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of two dose regimens of Certolizumab Pegol (CZP) in subjects with active axial Spondyloarthritis (axial SpA).
This Phase II, randomized, open-label, international, multicenter trial is designed to evaluate the safety and efficacy of rituximab monotherapy when given according to a dose intense regimen and to assess the safety, efficacy, and pharmacokinetics of ABT-263 when combined with dose-intense rituximab in previously untreated patients with B-cell CLL.
The three major Soil-Transmitted Helminths (STH), Ascaris lumbricoides, Necator americanus/Ancylostoma duodenal and Trichuris trichiura are among the most prevalent parasites worldwide. The objective of this multicentre international study is to define the efficacy of a single 400 milligram dose of albendazole (ALB) against these three STHs using a standardised protocol. The trial will be undertaken among school age children in seven countries - Brazil, Cameroon, Cambodia, Ethiopia, India, Tanzania (Zanzibar) and Vietnam - each with a different epidemiologic pattern of infection. A trial of this nature is urgently required because in spite of the wide usage of albendazole over the last 3 decades, there is still no key publication reporting the efficacy of the anthelmintic accurately, and to modern conventional standards, that can act as a central reference for the baseline efficacy. The latter is critically important because albendazole is now being used even more widely, as large scale mass treatment campaigns are being implemented in Africa and elsewhere, with the intention of reducing morbidity in children. Such large scale usage of a drug risks resistance developing, but resistance cannot be detected unless benchmark values for baseline efficacy are widely known.
