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.
This is a randomized, open label, multicenter phase III trial comparing the efficacy, safety, and tolerability of tisagenlecleucel to Standard Of Care in adult patients with aggressive B-cell Non-Hodgkin Lymphoma after failure of rituximab and anthracycline containing frontline immunochemotherapy.
A randomized, double-blind and prospective trial meant to evaluate the use of Glibenclamide on acute aneurysmatic subarachnoid hemorrhage. Patients will allocated randomly in two groups, one for 05 mg daily intake of glibenclamide for 21 days and another for control with placebo. General clinical data and late cognitive status will be accessed in both groups.
The purpose of this study is to compare the efficacy of ibuprofen, acetaminophen, chewing gum in reducing orthodontic pain. This study include 81 patients to be classified into 4 groups of 19 each: ibuprofen (400 mg), acetaminophen (500 mg), chewing gum and control. The patients in each group will receive 1 method immediately after placement of the initial archwire and every 6 hours for a week if they experiences pain. Pain perception will be recorded by the patients while jaw rest position and fitting back teeth at 2 hours, 24 hours, 2 days, 3 days, 7 days and 21 days after archwire placement, using a visual analog scale.
The purpose of this study is to compare the efficacy and safety of 26 weeks of delamanid (DLM) versus 26 weeks of isoniazid (INH) for preventing confirmed or probable active tuberculosis (TB) during 96 weeks of follow-up among high-risk household contacts (HHCs) of adults with multidrug-resistant tuberculosis (MDR-TB) (index cases). High-risk HHCs are those with HIV or non-HIV immunosuppression, latent TB infection, and young children below the age of 5 years.
To compare the efficacy of intramuscular injection of two anti-inflammatory drugs, Traumeel and Dexamethasone, used in the control of postoperative complications pain, edema and trismus after third molar extraction mandibular
The purpose of this trial is to investigate the mechanisms leading to weight gain during CPAP treatment for obstructive sleep apnea (OSA).
The purpose of this study is to termine if a different attentional focus would alter the motor control in cervical muscles during the cranio-cervical test.
Providing high quality care for dying patients and their families is very important. One way one can assess the care provided is to ask bereaved relatives to complete a questionnaire after their family member has died. The questionnaire can ask about their experiences and their thoughts about the care provided to their family member. One such questionnaire is the 'Care Of the Dying Evaluation' (or CODE). CODE has been developed with the help and support of bereaved relatives and has been used extensively within the United Kingdom. In this project the investigators want to use the CODE questionnaire to look at bereaved relatives' views about care provided in seven different countries within Europe and Latin America. In the first part of the project CODE was translated into the main language of each country. Volunteers and bereaved relatives in each country were asked to give feedback about whether CODE was easy to understand, sensitive, and easy to complete. Based on the feedback a common version of CODE that is suitable for use across all the countries was developed. In the next phase of the project, relatives who have recently experienced a bereavement where one of their family members has died from cancer in a hospital, will be invited to complete the CODE questionnaire about two months after the patient's death. The relatives may complete CODE on paper, using a computer, or by interview. The aim is to have 100 completed CODE questionnaires from each of the seven countries. The data from the questionnaires will be used to make a report on the current quality of care for dying cancer patients in hospitals across the seven countries. It will also be possible to compare the care between the countries and identify areas needing improvement. In the next phase of the project, health care professionals, researchers and bereaved relatives together will use their knowledge and experience to find effective ways to improve the weak areas identified, and assess the results of putting these changes into practice.
Mechanical heart valves (MHV) demand lifelong anticoagulation with vitamin K antagonists (VKA) due to the high thrombogenicity of the prosthesis. Rivaroxaban has previously been tested in experimental and animal models with encouraging results. The investigators recently sent for publication an experiment with 7 patients who used rivaroxaban in metallic prosthesis with encouraging results. In this way it was decided to do a randomized non-inferiority clinical trial comparing rivaroxaban with warfarin in patients with metallic prosthesis.
Recent studies have shown positive results in the application of phototherapy for the improvement of performance and acceleration of the healing process of the body homeostasis. Among the methods used to assess the recovery post-exercise has cardiac autonomic modulation assessed by heart rate variability (HRV), a tool widely used in sports to evaluate medium global behavior of the autonomic nervous system. Objective: analyze and compare the effect of a special protocol of phototherapy using different light sources interacting with a combined training with an autonomic modulation of heart rate in different moments (baseline; tracking daily; recovery post-exercise and after training). Method: 45 male participants will be allocated from a stratified randomization into three groups: control (n=15), placebo (n=15) and group special protocol of phototherapy (n=15). Participants will perform a combined training of sprints and squats twice a week for twelve weeks divided into two phases. The application of phototherapy and placebo was administered in phase 2, after sprints and just before the squat. The phototherapy was used combine different light sources and wavelength (red and infrared). Was analyze HRV in five moments: baseline; traking daily; week target of phase I and II; after training. The weeks target consist of training sessions with greater energy expenditure (largest intensity). The sphericity of the data was tested by Mauchly test. In case of violation of the sphericity assumption, the correction of Greenhouse-Geisser was performed. The data was analyzed using analysis of variance for repeated measures (Bonferroni post-test), which provide information on the effects of time, group and interaction. All statistical analyzes assume the significance level of 5%.
