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 study aims to investigate the behavioral effects, neural correlates and functional connectivity of cognitive training in patients with stroke
Mucopolysaccharidoses (MPS) are multisystemic diseases with significant clinical overlap between their types, with cardiac problems being among the most commonly observed manifestations and are also among the main causes of mortality in these patients. For some of the cardiovascular manifestations, such as aortic root dilation and valve diseases, there is no effective treatment currently available. Losartan, on the other hand, has been shown to be an effective drug for dilation of the aortic root, at least in animal models. This study aims to evaluate the safety and efficacy of losartan in patients with MPS VI and other mucopolysaccharidoses.
The purpose of the study is to evaluate the efficacy and safety of bintrafusp alfa (M7824) compared with pembrolizumab in participants with advanced NSCLC with high PD-L1-tumor expression, with no epidermal growth factor receptor (EGFR) mutation or anaplastic lymphoma kinase (ALK) translocation. The Phase III adaptive design allows for the option to recruit up to 584 patients based on pre-specified rules.
This is a phase III study of pembrolizumab plus platinum-based doublet chemotherapy with or without canakinumab in previously untreated locally advanced or metastatic non-squamous and squamous NSCLC subjects. The study will assess primarily the safety and tolerability (safety run-in part) of pembrolizumab plus platinum-based doublet chemotherapy with canakinumab and then the efficacy (double-blind, randomized, placebo controlled part) of pembrolizumab plus platinum-based doublet chemotherapy with or without canakinumab.
The study will compare the efficacy and safety of pembrolizumab plus trastuzumab in combination with standard of care (SOC) chemotherapy versus trastuzumab in combination with SOC chemotherapy in participants with HER2-positive gastric cancer. The primary hypotheses of the study are that pembrolizumab plus trastuzumab in combination with chemotherapy is superior to trastuzumab plus chemotherapy in terms of 1) progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR), and 2) overall survival (OS).
Growing evidences indicates that the Kangaroo Mother Method is associated with health benefits for the child and her mother. Improvements have been found in physiological parameters of the preterm infants assisted by the method. Some of them are the reduction of the heart rate and respiratory, as well as the increase of the body temperature and of the arterial saturation of oxygen. More recently, it has been observed that children submitted to the method present an improvement in muscle tone, by the increase in the electromyographic activity of the biceps brachii and hamstrings. These physiological changes can result in benefits for the child, with a positive influence on their development. It is well established that the preterm newborn has an important circulatory vulnerability, since the transition from fetal life to extrauterine life is a complex process in which the major changes are concentrated in the cardiovascular system and occur during the first Hours after birth accompanied by important consequences in physiological parameters, such as systemic vascular resistance, heart rate and blood flow in the organs. Therefore, global hemodynamic parameters have been studied in premature infants, especially after some intervention. It is worth noting, however, that these global parameters such as blood pressure, heart rate and arterial oxygen saturation do not reflect the existence of adequate tissue oxygenation, since they are macrocirculatory and non-microcirculatory parameters. In order to obtain reliable signals on tissue oxygenation, it is essential to study the microcirculation. To further explore the effects that Kangaroo Position promotes on the physiological aspects of the newborn, especially on hemodynamic parameters, we consider it important to study aspects that may, in fact, represent an adequate tissue oxygenation. Therefore, the objective of this study is to evaluate the effect of Kangaroo Position in the electromyographic activity and on hemodynamic parameters, by means of microcirculation/macrocirculation measurements.
Evaluate the safety and tolerability of sotorasib in adult subjects with KRAS p.G12C mutant advanced solid tumors. Estimate the maximum tolerated dose (MTD) and/or a recommended phase 2 dose (RP2D) in adult subjects with KRAS p.G12C mutant advanced solid tumors.
Stroke is a frequent complication of sickle cell disease (SCD), with varying levels of central nervous system (CNS) involvement. The summation of several ischemic events, even when silent, can lead to devastating consequences, from reduced academic performance to physical dependence. Despite knowledge that brain flow velocities evaluated by Doppler ultrasound identify pediatric SCD patients at a greater stroke risk (Adams et al, NEJM 1998; 339:5-11), this method is not able to predict the occurrence of strokes in adults. There is also no consensus on the management of adult patients in relation to primary and secondary prevention. The aim of this study is to evaluate the effects of the administration of Simvastatin on CNS structural and functional vascular changes in 30 adult patients with SCD (SS and Sβ), above 35 years of age, observed through Magnetic Resonance Imaging (MRI). The data on the effect of simvastatin on disease manifestations is quite scarce, however this drug reportedly significantly reduces plasma concentrations of adhesion molecules and inflammatory markers, such as E-selectin, VEGF, CRP and IL-6 (Hoppe et al, BJH 2011; 153:655-663; Hoppe et al, BJH 2017;177:620-629). Thus, in addition to the search for early diagnostic markers and risk stratification for primary or recurrent stroke, we will also compare CNS images before and 12 months after the administration of Simvastatin. The drug alter stroke recurrence rates in the general adult population, but their effects on vascular changes in patients with SCD have not yet been adequately elucidated. This is particularly important because these are low cost drugs which present good tolerability, and could be part of the therapeutic arsenal of SCD, even in low income settings. Concomitantly with the CNS evaluation, this study also intends to investigate molecular pathways that may be affected by the drugs. We will evaluate microvesicle release patterns, as well as the content of microRNAs possibly involved in the occurrence of stroke, in addition to metabolomic studies and plasma cytokine profile.
This extension study will evaluate the effectiveness and safety of ocrelizumab in multiple sclerosis (MS) participants who were previously enrolled in a F. Hoffmann-La Roche (Roche) sponsored ocrelizumab phase IIIb/IV trial (i.e. the Parent, P-trial).
The purpose of this study is to evaluate efficacy of golimumab in inducing clinical remission as assessed by the Mayo score, in pediatric participants with moderately to severely active ulcerative colitis (UC). In addition, the safety profile of golimumab, in pediatric participants with moderately to severely active UC will be assessed.
