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 purpose of this study is to determine whether nivolmab alone or the combination of nivolumab and ipilimumab versus placebo, is safe and effective for delaying or preventing recurrence of cancer in participants who have experienced partial or entire removal of a kidney.
The main purpose of this study for patients with gastric or gastroesophageal cancer is to evaluate how well the tumor is responding to treatment with nivolumab by itself, or in combination with ipilimumab. For patients with esophageal cancer, the main purpose is to evaluate how well the tumor is responding to treatment with the combination of nivolumab and ipilimumab.
Study was designed to evaluate efficacy of autologous platelet rich plasma (PRP) injections guided by ultrasound for treatment of knee osteoarthritis.
This study is a randomized controlled trial, designed to evaluate the effect of structured physical exercise sessions on the spontaneous physical activity energy expenditure and caloric intake in overweight adults. The design employs a parallel three-group experimental arms: (1) a moderate exercise group (MEG); (2) a vigorous exercise group (VEG); and a control group (CG) without physical exercise sessions.
This clinical study has as main objective to evaluate if the Nasal Septum Autologous Chondrocytes Transplantation for Condylar Resorption is safe and effective in the treatment of degenerative lesions of temporomandibular joint (TMJ). It is a case series, in which 10 participants with diagnosis of condylar reabsorption of TMJ will be selected, with orthognathic surgery indicated. Orthognathic surgery is conventionally indicated for patients with condylar resorption to correct dentofacial deformity and, therefore, will not be performed only in function of this clinical study. The selected participants will be submitted to nasal cartilage biopsy, for isolation and preparation of the chondrocytes. The only experimental group to be evaluated will be the group treated with autologous chondrocytes diluted in hyaluronic acid. The experimental treatment will be performed 15 days after orthognathic surgery, and will be injected through arthrocentesis. Clinical follow- up will be performed in the following periods: 7 and 15 days and 1, 3, 6 and 12 months after treatment. During the consultations, participants will also be evaluated for the intensity and severity of the pain experienced, as well as the disability related to it, through the same system used for the diagnostic classification (RDC / TMD). Imaging of the TMJ will be performed before, 6 and 12 months after the injection of the experimental treatment for bone and cartilaginous joint tissue analysis. Autologous chondrocyte implantation is expected to promote the regeneration of TMJ cartilage tissue safely and effectively.
Autonomic and endothelial imbalance in post menopause women raise the need to manage cardiovascular risk. Yoga poses and breathing control present controversial results on prevention and treatment of hypertension.. The aim of this study is to compare the effect of 12 week intervention based on yoga poses and their muscle contractions known as bandhas (pelvic floor, core and throat/neck) and ujjayi pranayama (victorious breath) on autonomic modulation, endothelial function, arterial stiffness, aerobic capacity and cognitive function of hypertensive post-menopausal women.
This trial is conducted in Africa, Asia, Europe, North and South America. The aim of the trial is to compare the effect of once-weekly (OW) dosing of subcutaneous semaglutide (1.0 mg) versus once-daily dosing of oral canagliflozin (300 mg) on glycaemic control in subjects with type 2 diabetes (T2D) on a background treatment of metformin
This study evaluated whether physiotherapy is efficient in sputum induction and in evaluation of pulmonary inflammation in asthmatic children.
The present study is a randomized school-based trial of a sample of 5th and 6th grade students from 10 public schools in the municipality of Duque de Caxias, metropolitan area of Rio de Janeiro, Brazil. The aim is to investigate whether adding nudging actions to the intervention group of PAAPPAS trial (PAAPAS Study, NCT02711488) increase fruits, vegetables and water consumption and daily energy expenditure, in a factorial design.
The aim of this project is to compare the efficacy and the local effect of the association of single or repeated application of photodynamic therapy (PDT) with antibiotic agents using Amoxicillin + Metronidazole or Clarithromycin in the treatment of patients with Generalized Aggressive Periodontitis (GAgP).
