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.
Comparison between internal jugular vein versus via axillary vein with single-incision for placement of implantable ports in cancer patients. Investigators are recruiting 240 patients and randomizing 120 for each arm. Primary outcome is early complications, until 30 days and secondary outcome late complications, between 30 days and 6 months. The follow-up is 12 months.
To achieve global hepatitis C virus (HCV) elimination by 2030, 80% of the ~71 million people with chronic HCV infection will need to be treated, necessitating simplification of treatment delivery and associated laboratory monitoring without compromising efficacy or safety. The COVID-19 pandemic has further highlighted the need for innovative models of health care delivery that minimize face-to-face patient-provider contact. The purpose of this study was to evaluate the feasibility, safety, and efficacy of a minimal monitoring (MINMON) strategy to deliver interferon- and RBV-free, pan-genotypic DAA therapy to treat active HCV in HCV treatment naïve participants.
The purpose of this study was to confirm the preliminary evidence from early clinical trials that midostaurin may provide clinical benefit not only to AML patients with the FLT3-mutations but also in FLT3-MN (SR<0.05) AML (FLT3 mutant to wild type signal ratio below the 0.05 clinical cut-off). This study evaluated the efficacy and safety of midostaurin in combination with daunorubicin or idarubicin and cytarabine for induction and intermediate-dose cytarabine for consolidation, and midostaurin single agent post-consolidation therapy in newly diagnosed patients with FLT3-MN (SR<0.05) AML.
The aim of this clinical trial is to evaluate, the effects of inspiratory muscle training program in inspiratory muscle function, functional capacity, quality of life, lung function, breathing pattern and chest wall motion in patients with advanced lung disease. Patients were evaluated before the inspiratory muscle training, after 8 weeks of training and at follow-up which was performed 3 months after the end of the intervention.
Primary Objective: To evaluate the efficacy of alirocumab administered every 2 weeks (Q2W) and every 4 weeks (Q4W) versus placebo after 24 weeks of double-blind (DB) treatment on low-density lipoprotein cholesterol (LDL-C) levels in participants with heterozygous familial hypercholesterolemia (heFH) 8 to 17 years of age on optimal stable daily dose of statin therapy ± other lipid modifying therapies (LMTs) or a stable dose of non-statin LMTs in case of intolerance to statins. Secondary Objectives: - To evaluate the efficacy of alirocumab versus placebo on LDL-C levels. - To evaluate the effects of alirocumab versus placebo on other lipid parameters. - To evaluate the safety and tolerability of alirocumab in comparison with placebo. - To evaluate the efficacy, safety, and tolerability of alirocumab after open label treatment. - To evaluate the development of anti-alirocumab antibodies.
Primary Objective: To evaluate the efficacy of alirocumab (75 or 150 milligrams [mg] depending on body weight [BW]), administered every 2 weeks (Q2W), on low-density lipoprotein cholesterol (LDL-C) levels at Week 12 of treatment in children and adolescents with homozygous familial hypercholesterolemia (hoFH) of 8 to 17 years of age on top of background treatments. Secondary Objectives: - To evaluate the efficacy of alirocumab after 24 and 48 weeks of treatment on LDL-C levels. - To evaluate the effects of alirocumab on other lipid parameters (eg, apolipoprotein B [Apo B], non-high density lipoprotein cholesterol [non-HDL-C], total cholesterol [Total-C], high density lipoprotein cholesterol [HDL-C], lipoprotein a [Lp (a)], triglycerides [TG], apolipoprotein A-1 [Apo A-1] levels) after 12, 24, and 48 weeks of treatment. - To evaluate the safety and tolerability of alirocumab up to 48 weeks of treatment.
Professionals working in polluted areas may present increased airways symptoms and dysfunction. Rhinopharyngeal retrograde clearance (RRC) has been used to improve mucus clearance in infants with bronchitis and bronchiolitis. Flushing the nasal cavity with saline (S) has been used to reduce nasal inflammation in rhinitis and sinupathies. The aim of this study was to assess the effects of RRC and RRC plus S (RRC+S) on the airways in professional motorcyclists. Twenty-four male motorcyclists (mean age 36 years) were randomly assigned to RRC or RRC+S. Subjects were assessed at baseline and 15 days after interventions for airways assessments by saccharin test, mucus contact angle, cellularity in nasal lavage and airways symptoms with the use of SNOT-20 questionnaire. Data were analyzed by nonparametric ANOVA for repeated measures with Bonferroni´s correction. A passive nitrogen dioxide monitoring system was used to assess the mean personal air pollution exposure along the study period (NO2). The association between NO2 and the airways outcomes was analyzed by Spearman correlation test. At baseline, the two groups were similar in clinical, demographics and working aspects. From them, 100% had airways symptoms complaints and 33% had nasal MCC impairment. After treatments, both groups presented improvements in airways symptoms and nasal MCC. However, increased number of macrophages and ciliated cells were observed in nasal lavage of both groups. No associations between nitrogen dioxide and the outcome variables were detected. Rhinopharyngeal retrograde clearance seems to be useful in the clinical management of the upper airways symptoms and dysfunction in adults.
The mortality and postoperative complications of high risk surgeries vary in the different series. The management of this group of patients in intensive care unit (ICU) is fundamental to improve these outcomes. The objective of this study will be to evaluate whether the use of bedside ultrasound has an impact on the management of this group of patients with a consequent reduction in the incidence of acute renal failure in ICU and, secondarily, the incidence of associated complications. All adult patients (≥ 18 years old) admitted to ICU at Hospital das Clinicas of UFMG in the immediate postoperative period of major surgery with indication of ICU monitoring will be included and randomly randomized to the control or intervention group. The control group will be conducted by the intensive care physicians in charge without the US, while the second group will be conducted based in US findings. The US protocol will consist of a pulmonary US in four windows in each hemithorax , qualitative assessment of contractility and variation of inferior vena cava diameter. The primary outcome will be the development of acute renal failure as measured by the KDIGO score. Secondary outcomes will be length of ICU and hospital stay, ICU and 28 days mortality, length spent in mechanical ventilation, accumulated water balance, noradrenaline and dobutamine dose. Serum and urinary biomarkers will also be evaluated. Key words: ultrasound, high-risk surgery, intensive care
The purpose of this study is to present a descriptive analysis of demographic and clinical characteristics of the participants, as well as of the treatment patterns for multiple myeloma (MM) in Brazil.
This study is a multicentre, international, randomized controlled trial of tranexamic acid (TXA) versus placebo and, using a partial factorial design, of a perioperative hypotension-avoidance versus hypertension-avoidance strategy.
