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.
Data from niraparib treatment is not available in real-world setting in Latin America. The present study aims to collect data from patients treated with niraparib within the Latin America Expanded Access Program (EAP) in clinical practice in Brazil and Argentina and who meet the eligibility criteria for this study, without additional intervention.
Participants with moderate depressive symptoms measured by PHQ-9 will be randomized to receive auricular acupuncture. The triple blinded procedure will be conducted in 12 sessions (6 weeks). The primary outcome is the response to the treatment 3 months after inclusion.
The primary purpose of this study is to evaluate the efficacy of perioperative dostarlimab compared with standard of care (SOC) in participants with untreated T4N0 or Stage III (resectable), defective mismatch repair/ microsatellite instability high (dMMR/MSI-H) colon cancer.
This study will evaluate the efficacy of two dosing regimens of adagrasib (600 mg BID versus 400 mg BID) in patients with NSCLC with KRAS G12C mutation.
The purpose of this study is to assess the efficacy and safety of a novel immunotherapy candidate, tobemstomig, in combination with nab-paclitaxel, for patients with previously untreated, locally advanced, unresectable or metastatic (Stage IV) programmed death-ligand 1 (PD-L1)-positive triple-negative breast cancer (TNBC).
The aim of this study is to evaluate the effectiveness of reorganization in Primary Health Care teams and individualized glycemic targets for type 2 diabetes.
Prospective phase 2 study to evaluate the safety and efficacy of ultra-hypofractionated adjuvant radiotherapy in 5 fractions of 5.7 Gy in patients aged over 65 years.
This is an international, open-label, stratified randomized controlled trial with Bayesian adaptive stopping rules to compare the effects of therapeutic-dose heparin vs. usual care pharmacological thromboprophylaxis on outcomes in patients admitted to hospital with community acquired pneumonia (CAP).
The aim of this study is to compare different non-pharmacological interventions in Type 2 diabetic people, testing their efficiency to improve metabolism and inflammation. The investigators will compare the effects of Heat Therapy (HT) and Strength training (ST), for 12 weeks, to test which one is more effective to improve participants health. Heat Therapy consists in submitting a person to an environmental chamber, initially set at 55 degrees Celsius on three non-consecutive days of the week. Each session will last 60 min. ST consists in supervised exercise in a gym on three non-consecutive days of the week. Each session will last ~60 min and will consist of a warm up, the resistance training and a cool down. All sessions will be conducted by qualified sport and exercise scientists for 12 weeks. A third group of people will stay sedentary without any other intervention for 12 weeks. Before, and after the end of the intervention blood samples will be collected to analyze metabolic parameters as well as inflammatory markers. The investigators hypothesize that ST and HT will reduce HbA1c levels, improve metabolic and inflammatory profile, dysbiosis, and the anti-inflammatory heat shock response (HSR).
The role of obstructive sleep apnea (OSA) on chronic kidney disease (CKD) is not clear. This randomized clinical trial will test the impact of OSA treatment on blood pressure (BP) and on the estimated glomerular filtration rate (eGFR) in patients with CKD IIIb and IV (eGFR 44-15 ml/min). A polygraph will be performed to assess the presence of OSA (defined by an apnea-hypopnea index ≥15 events/hour). Patients with OSA will be randomized to use continuous positive upper airway pressure (CPAP) or to maintain optimized clinical treatment for BP control. Antihypertensive medication adjustments will be allowed using a standard protocol for both groups by the same researcher, who will not have access to CPAP follow-up. In addition to clinical (including BP and ambulatory BP monitoring, ABPM) and laboratory assessments at baseline, we will follow up at 3 months, 6 months, 9 months and 12 months after randomization of the proposed outcomes. Target organ damage analyses, such as the retina and echocardiography, will be performed at baseline and after 1 year of randomization. Primary objective: to compare the effect of CPAP on the need to adjust antihypertensive medication to control systolic BP (<130mmHg) in patients with CKD; secondary objectives: 1) to evaluate the reduction in systolic and diastolic BP by office and ABPM; 2) assessment of nocturnal BP dipping; 3) to evaluate the impact of OSA treatment with CPAP on eGFR during follow-up; 4) to evaluate the impact of OSA treatment with CPAP on the evolution of albuminuria; 5) assessment of other target organ damage such as retinopathy and cardiac remodeling; 6) to evaluate the impact of OSA treatment with CPAP on the possible delay for renal replacement therapy or end-stage renal disease (eGFR <15ml/min and dialysis); 7) to evaluate the impact of OSA treatment with CPAP on the quality of life of patients with CKD. With a significance level of 5% and study power of 90%, two-tailed hypothesis testing, 74 patients with OSA per group, i.e., 148 patients in total, will be required to assess the primary endpoint (we estimate that 25% and 50% of patients in control and CPAP groups will not need to adjust their antihypertensive medication at follow-up, respectively).
