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.

A single-arm, open-label study to assess the overall safety of rovalpituzumab tesirine in participants with relapsed or refractory delta-like protein 3 (DLL3) expressing small cell lung cancer by evaluating the frequency of high grade (>= Grade 3) select treatment-emergent adverse events (TEAEs).
Introduction: The Obstructive Sleep Apnea (OSA) is characterized by obstructed superior airway during sleeping period promoting intermittent hypoxia-reoxygenation events. These events cause consequences such as cardiorespiratory and peripheric muscle structure alterations, which can cause reduction of the exercise tolerance. In this sense the continuous positive airway pressure (CPAP) is important to decrease the repercussions of the illness and cooperate to maintain the exercise functional capacity. To measure this capacity, one good option is the six-minute step test (6MST), that is low cost and submaximal, in addition to being adaptable and portable. However, there are doubts if it´s really capable to determinate the functional capacity of exercise of individuals with OSA treated with CPAP. Objective: Evaluate the validity and reproducibility of 6MST to determine the functional capacity of exercise in individual with OSA treated with CPAP and develop a model of a reference equation for the performance of the test in this population. Material and methods: This is an observational, prospective and cross-sectional study, in which will be evaluated 132 volunteers (66 men and 66 women), with age between 18 and 65 years, diagnosed with OSA of moderate and severe degree, treated with CPAP for a minimum of three months, recruited of the ambulatory of pneumology of Otávio de Freitas Hospital. Initially will be collected personal and anthropometric information, answered to sleep questioners, quality of sleep and physical exercise, also respiratory muscle strength and lung function. The realization of the tests to evaluate the functional capacity of exercise will be done in two days with a maximum of seven days between the tests. In each day, the volunteers will do two 6MST and two six-minute walk test (6MWT), which order will be determined by randomization. Expected Results: It is expected that the 6MST to be showed as reproducible and capable to quantify the functional capability of exercise in individuals with OSA treated with CPAP.
Breast cancer is the most frequent tumor site among women in the world (FERLAY et al., 2015). In Brazil, estimates for the year 2017 indicate the occurrence of about 57,960 new cases (56.2 cases per 100,000 women); (Brazil - Ministry of Health, 2015). The increase in adjuvant therapies resulted in an estimated increase of 22 million cancer survivors worldwide (GOLDSTEIN et al., 2012). However, as survival rates increased, more women faced complications related to diagnosis and treatment (ABRAHMS et al., 2016). Adjuvant radiotherapy is a frequent treatment in breast cancer and fatigue it is the main adverse effects (HICKOK et al., 2005). Measures of intervention through physical activity have shown benefits in the increase of the functional capacity that generates a reduction of effort and decrease of the fatigue (MARKES et al., 2009). General Objective: To evaluate the influence of Mat Pilates on fatigue, quality of life, functional capacity, flexibility, lymphedema, radiodermatitis and depression, in the women with breast cancer and with an indication of adjuvant radiotherapy, at the Cancer Hospital III of the National Cancer Institute (INCA). After recruitment, women will be allocated randomly in: Intervention Group (Mat Pilates and usual activities) and Control Group (usual activities). Patients in the intervention group will be submitted to 10 sessions of Mat Pilates for a period of 5 weeks (from beginning to end of adjuvant radiotherapy). Patients assigned to the control group will not participate in the Mat Pilates program, but will maintain the usual exercises for upper limbs, guided by physiotherapists in the postoperative period. In both groups, patients will be submitted, functional capacity assessment, flexibility assessment, assessment of the presence of lymphedema, and questionnaire application of fatigue, quality of life, level of physical activity and depression. Will be performed a descriptive analysis of the population. Univariate logistic regression will be performed between the outcomes according to the exercise groups and also, for the possible confounding variables. The variables with p<0.20 will be selected for adjustment in the construction of the multiple logistic regression model. Those with p<0.05 and/or with clinical significance will be maintained in the model.
This study evaluate the Duodenal Ileal Interposition with Sleeve Gastrectomy for Type 2 Diabetes Mellitus in grade 1 obesity and overweight patients.
Sepsis has been characterised as a dysregulated host response to infection. Adjunctive therapies targeting the inflammatory cascade are being increasingly explored, although to date, have failed to demonstrate consistent benefit, and sepsis continues to manifest poor outcomes. Hospital mortality in patients with septic shock remains as high as 22% in Australia and New Zealand. From a global perspective, 31 million sepsis and 19 million severe sepsis cases are expected to be treated in hospitals all over the world per year. To date, experimental data have reported that both high dose intravenous vitamin C and corticosteroids attenuate the acceleration of the inflammatory cascade and possibly reduce the endothelial injury characteristic of sepsis, enhance the release of endogenous catecholamines and improve vasopressor responsiveness. Therefore, the investigators plan to conduct a feasibility pilot prospective, multi-centre, randomised, open-label, trial in ICU patients with septic shock to test whether the intravenous administration of high dose Vitamin C (6g/d), Thiamine (400mg/d) and Hydrocortisone (200mg/d) leads to a more rapid resolution shock and vasopressor dependence.
The overall aim of this study is to evaluate the safety, immunogenicity and dose sparing effects of H7N9 influenza antigen formulated with 2 different adjuvants .
Microcephaly associated with Congenital Syndrome of the Zika virus (SCVZ) was highlighted due to atypical structural and behavioral changes of the central nervous system. Such changes contribute to the appearance of functional impairments and difficulties of adaptation of the child to the necessary therapeutic follow-up. In this context, the search for adjuvant therapies that allow better management of these alterations has grown and, given its advantages, aquatic physiotherapy may be an auxiliary resource in the care of this population. The aquatic environment is capable of promoting a state of relaxation that, when associated with a kinesiotherapy protocol, is believed to have this potentiated effect. Thus, our objective will be to evaluate the efficacy of aquatic physiotherapy on the level of stress and muscle tone in children with microcephaly associated with SCVZ. A crossover, randomized, controlled and blind study will be carried out with children between 3 and 24 months of age, who will undergo two interventions: aquatic physiotherapy and water immersion. The evaluation of muscle tone will be performed through the Tardieu scale before and after the intervention; the physiological parameters (heart and respiratory rate, oxygen saturation and temperature) and the stress level will be evaluated before, immediately after and 30 minutes after the intervention. In addition, questionnaires will assess the child's behavioral state, level of irritation and sleep characteristics. For data normalization the Shapiro Wilk Test will be applied; the percentage values and relative frequency will be used for the descriptive analysis and for the numerical variables the values of mean and standard deviation or median and interquartile range. The paired T and ANOVA tests for repeated samples will be applied, which will analyze the intra-group time factor for the dependent variables of each individual. And for intergroup analysis, the variables may be submitted to the T-Test for independent or Mann-Whitney samples.
