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.
Beta-blockers are useful tools for the prevention of hemodynamic instability in the manipulation of airways. The main objective of the present study is to evaluate the effectiveness of using esmolol in attenuating hemodynamic responses at the time of tracheal extubation, by assessing the incidence of tachycardia in relation to placebo.
In this study the investigators will evaluate chronotype, food intake pattern, and cardiovascular risk markers of elder individuals with OSA, in use of CPAP, when submitted to two weeks of CPAP withdrawal.
IMC-F106C is an immune-mobilizing monoclonal T cell receptor against cancer (ImmTAC ®) designed for the treatment of cancers positive for the tumor-associated antigen PRAME. This is a first-in-human trial designed to evaluate the safety and efficacy of IMC-F106C in adult patients who have the appropriate HLA-A2 tissue marker and whose cancer is positive for PRAME.
A phase III, randomized, multi-center, open label clinical trial that will examine whether endovascular treatment is superior to standard medical therapy alone in patients who suffer a large vessel anterior circulation ischemic stroke within 8-24 hours from time last seen well
This study will evaluate the safety, tolerability, pharmacokinetics, and activity of XmAb24306 alone or in combination with a checkpoint inhibitor treatment in participants with locally advanced or metastatic solid tumors.
Currently, there is no standard and indicated standard access route for uterine removal in the uterine transplant donor patient. The aim of the study is to show the feasibility of performing this procedure by replicating in our center the results found in other recent studies and to try to reduce the surgery time for both the donor and recipient patients.
Ventricular tachycardia (VT) is the main cause of sudden death in patients with structural heart diseases. The use of ICD (implantable cardio-defibrillator) could prevent sudden death, however, the occurrence of repetitive shock decreases significantly the quality of life and could increase the mortality rate. Chagas disease in our environment is the most common heart disease and often associated with the occurrence appropriate ICD therapies. The chronic treatment of VT aims to prevent recurrences with the use of antiarrhythmic drugs and catheter ablation, but in many cases, these treatments are insufficient to control the VT. Cardiac Sympathetic Denervation by bilateral sympathectomy has been described as an alternative treatment of VT refractory to medical treatment and radiofrequency ablation, especially in patients with channelopathies. This treatment could have a role in patients with structural heart disease. The objective of this study is to evaluate the efficacy of the bilateral sympathectomy in the reduction of ventricular tachycardia in patients with Chagas cardiomyopathy. In this pilot study, the investigators will select 45 patients with Chagas cardiomyopathy with ICD who presented at least four ICD therapies in the prior six months. These patients will be randomly assigned to three groups, 15 patients in medical therapy group, 15 in catheter ablation and 15 in bilateral sympathectomy.
Tumors in the oral region occur more frequently in men over 40, but can affect people of both gender and all ages, even children. The prevention of oral cancer acquires relevance in public health, particularly if the investigators consider that the preventive approach is compatible with the nature of this disease, as the mouth favors easy visual access. The objective of this study is evaluation the prevalence of oral and perioral injuries in workers who were exposed to the sun on the beaches, investigating possible associations of a sociodemographic, occupational and general health nature.
A study to find out whether olaparib is safe and well tolerated when administered to children and adolescents with solid tumours.
