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 objective of the study is to evaluate the effectiveness of telemonitoring in the dysfunctions of the upper limbs in activities of daily living, quality of life and prevention of lymphedema in women undergoing treatment for breast cancer. Secondarily, to analyze the degree of satisfaction in the proposed treatment modality. This is a randomized controlled trial, double blind (evaluator and patient), parallel in three groups (synchronous telemonitoring group, asynchronous telemonitoring group and control group). The protocol will last six weeks, and quality of life, upper limb functionality, and risk of lymphedema will be evaluated. Both intervention groups will be submitted to a kinesiotherapy program three times a week, with synchronous and asynchronous monitoring, while the control group will receive usual post cancer orientations. Kinesiotherapy protocol in synchronous form compared to the usual recommendations in remote form is expected to show superior result in upper limb function and quality of life of women after breast cancer.
This study will evaluate the safety, pharmacokinetics, and efficacy of alectinib in children and adolescents with ALK fusion-positive solid or CNS tumors for whom prior treatment has proven to be ineffective or for whom there is no satisfactory standard treatment available.
The purpose of this pediatric study is to evaluate the drug levels, efficacy and safety of Deucravacitinib in pediatric participants aged 4 to <18 years with moderate to severe plaque psoriasis. This study includes two cohorts; Cohort 1 (age 12 to <18 years) and Cohort 2 (age 4 to <12 years), with two parts; for each cohort. Part A will evaluate the drug levels of BMS-986165 to enable selection of 2 dose levels to be studied in Part B. Part B will assess the efficacy and safety of two dose levels in pediatric participants with moderate to severe plaque psoriasis. The 5-year long-term extension (LTE) period will observe the long-term safety and tolerability of deucravacitinib in pediatric participants with psoriasis who have completed Parts A or B of the study.
The primary purpose of this study is to evaluate the efficacy of ION363 on clinical function and survival in carriers of fused in sarcoma mutations with amyotrophic lateral sclerosis (FUS-ALS).
Neurological dysfunction continues to be one of the complications of considerable concern in patients undergoing cardiac surgery. It was previously reported in the literature, that cerebral oxygen desaturation during cardiac surgery was associated with an increased incidence of cognitive impairment. This study aims to determine whether continuous monitoring of cerebral oximetry improves the neurocognitive outcome in coronary artery bypass surgery when associated with predetermined intervention protocol to optimize cerebral oxygenation.
Acute myocardial injury has been a finding of variable frequency among patients diagnosed with COVID-19. It is now recognized that cTnI levels are strongly associated with increased mortality. The mechanisms underlying the myocardial injury remain unknown, and it is not clear whether they reflect local/systemic inflammatory process and/or cellular ischemia. Both myocardial ischemia and ventricular dysfunction result in dramatic changes in mitochondrial oxidative metabolism. These changes involve an increase in the rate of cytoplasmic anaerobic glycolysis to compensate for the decrease in mitochondrial adenosine triphosphate (ATP) production. The rest of the mitochondrial oxidative metabolism originates mainly from the β-oxidation of free fatty acids, which occurs at the expense of glucose oxidation. Trimetazidine is a competitive inhibitor of the enzyme 3-ketoacyl coenzyme A (CoA) long-chain thiolase (3-KAT), the last enzyme involved in the oxidation of fatty acids. Stimulation of glucose oxidation by trimetazidine results in a better coupling between glycolysis and glucose oxidation, with a consequent decrease in lactate production and intracellular acidosis, present in situations of myocardial ischemia or heart failure. Thus, the PREMIER-COVID-19 study was designed to test the hypothesis that the use of trimetazidine associated with usual therapy in patients admitted with a diagnosis of moderate to severe acute respiratory syndrome by SARS-CoV2 infection reduces the extent of acute myocardial injury assessed by the peak release of ultra-sensitive troponin compared to usual therapy.
A 2-year, phase 3, multicentre, randomised, parallel-group, sham-controlled, double-masked study. Primary efficacy will be determined at Week 52.
To evaluate the efficacy and safety of second uterine curettage in patients with low-risk non-metastatic GTN.
Around 230 million major procedures are performed worldwide each year. Postoperative complications after major surgery, especially in solid organ transplants, are associated with a significant increase in costs and mortality. Major bleeding episodes in major surgeries such as liver transplantation are related to a significant impact on morbidity and mortality. In this multicenter study, we aimed to compare the efficacy of tranexamic acid when compared to placebo, administered after anesthetic induction and in continuous infusion during the procedure, on the rate of intraoperative bleeding in adult patients undergoing liver transplantation. Considering its mechanism of action and its pharmacological and clinical properties, we expect to observe a significant reduction in the bleeding rate and in the need for blood components in the perioperative period of adult patients undergoing orthotopic liver transplantation. In this study, only adult ASA III to IV patients (18 to 70 years old), scheduled for orthotopic liver transplantation at the Hospital de Clínicas de Porto Alegre, Santa Casa de Porto Alegre and at the Hospital das Clínicas of the University of Sao Paulo will be included. Exclusion criteria consider patients with a history of acute arterial thrombosis or venous thromboembolism (<1 month), patients with a history of known thrombophilia, Budd-Chiari syndrome, primary biliary cholangitis, primary sclerosing cholangitis, patients with reduced left ventricular function ( ejection fraction <40%), pulmonary hypertension, preoperative pulmonary edema, or severe preoperative hemodynamic changes requiring the use of vasoactive drugs, planned use of tranexamic acid systemically during surgery, hypersensitivity or known allergy to acid tranexamic, history of seizure disorder, patients who have recently suffered a stroke or myocardial infarction (<1 month), patients with subarachnoid hemorrhage in the last 30 days and patients previously undergoing cranial neurosurgery. Major bleeding in this study will be defined as bleeding that results in hemoglobin ≤ 8.0 g / dL and the patient receiving a transfusion of ≥ 1 unit of red blood cells; results in a drop in hemoglobin ≥ 4.0 g / dL and the patient receives a transfusion of ≥ 1 unit of red blood cells; results in the patient receiving a transfusion of ≥ 4 units of red blood cells over a 24-hour period; or bleeding leading to surgical reintervention.
