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.
Randomized, Double-blind, Controlled, Crossover, in which 68 subjects (34 males and 34 females) will receive, in each stage, an application of 4 UI, subcutaneous, single dose, of the investigational drug (Recombinant Human Somatropin - Biomatrop) and the comparator (Recombinant Human Somatropin - Hormotrop) according to randomization to evaluate the Non-inferiority of Pain Intensity After the Application of Hormotrop, using Visual Analogue Scale (0-10cm) and record the incidence of adverse events.
This Phase 4, randomized, double-blind, placebo-controlled study will evaluate the pharmacokinetics (PK) and safety of OCA treatment in participants with PBC and moderate to severe hepatic impairment over a 48-week treatment period. Participants who have completed their 48-week double blind treatment period will continue double-blind treatment until all randomized participants have completed their 48-week treatment period and the database for that period is locked. An open-label extension study in which all participants receive OCA will be considered following review of blinded safety and PK data.
Approximately 50% of coronary events occur in previously asymptomatic patients. Thus, the early detection of the individuals at higher risk became an important research target within the current cardiology. The various clinical scores used present a predictive accuracy for ischemic events, evaluated by the ROC curve, which ranges from 0.73 to 0, 79. Therefore, the introduction of new non-invasive techniques for the detection of atherosclerosis aims to allow a more adequate classification of risk. The development of radiological techniques, fundamentally coronary angiotomography of multiple detectors (CAMD) and electron beam computed tomography-EBCT‖, demonstrated that the degree of coronary calcification correlates with endothelial lesion and individual prognosis in the long term. Notably, the calcium score has a weak correlation with the severity of coronary stenosis per se, possibly due to variations in arterial remodeling due to coronary calcification. On the other hand, the CAMD allows the detection of a small magnitude atheromatous disease, not diagnosed clinically, nor by tests provoking ischemia, or even by coronary catheterization. The clinical relevance of the small magnitude atheromatous disease diagnosed by the ACMD and its correlation with plaque vulnerability markers, mainly platelet aggregation, vascular reactivity, and inflammation are still not well determined. This is a case and control study and we will enrolled 90 patients with low and medium risk of cardiovascular event whose cases should present discrete plaques in the CAMD e controls should present none plaque in coronary stenosis
Mucopolysaccharidoses (MPS) are multisystemic diseases with significant clinical overlap between their types, with cardiac problems being among the most commonly observed manifestations and are also among the main causes of mortality in these patients. For some of the cardiovascular manifestations, such as aortic root dilation and valve diseases, there is no effective treatment currently available. Losartan, on the other hand, has been shown to be an effective drug for dilation of the aortic root, at least in animal models. This study aims to evaluate the safety and efficacy of losartan in patients with MPS VI and other mucopolysaccharidoses.
Xerostomia is a quantitative and qualitative alteration of saliva, a symptom present in individuals who make continuous use of medications to control chronic diseases, including hypertension. Difficulties in mastication, swallowing, phonation and palate are present, besides oral burning syndrome, periodontal disease, root caries and bad breath that will interfere in the quality of life, making it difficult to socialize in society. Currently, the methods presented for treatment of xerostomia are palliative, so their use does not consist of an effective treatment. The objective of this study is to evaluate the efficacy of photobiomodulation in the production of saliva in patients with xerostomia induced by antihypertensive drugs. The method consists in the application of the low intensity laser in the three pairs of salivary glands - parotid, submandibular and sublingual. The parameters that will be used are: Laser Diode ArGaAl, DMC, 808nm, 4J per point, continuously and in contact with the irradiated surface, resulting in irradiance of 3571 mW/cm2, distributed as follows: 6 points in each parotid, 2 points in each sublingual (external) and two in each submandibular (internal), totaling 16 extra oral and 4 intra oral, totaling 20 points. The exposure time will be 40s per point, corresponding to 800s per session and 3600s at the end of the four treatment sessions. The radiant exposure will be 142J/cm2. The control group will have a simulation of the application of the laser, with the device turned off. Because it is an infrared light, it is invisible and this will not induce the patient to notice that the device is turned off. In the group that receives the photobiomodulation the device will have its timer turned off, to avoid the perception of sound difference. At the end of the sessions, a sample of saliva will be collected, which will be compared to the initial sample.
The purpose of the study is to evaluate the efficacy and safety of bintrafusp alfa (M7824) compared with pembrolizumab in participants with advanced NSCLC with high PD-L1-tumor expression, with no epidermal growth factor receptor (EGFR) mutation or anaplastic lymphoma kinase (ALK) translocation. The Phase III adaptive design allows for the option to recruit up to 584 patients based on pre-specified rules.
The hyperinflation ventilator was performed in different modalities and ventilatory adjustments, with total pressure of 40cmH2O. The inspiratory volume, inspiratory time, mean airway pressure, inspiratory and expiratory flow, and bias flow were evaluated.
This is a phase III study of pembrolizumab plus platinum-based doublet chemotherapy with or without canakinumab in previously untreated locally advanced or metastatic non-squamous and squamous NSCLC subjects. The study will assess primarily the safety and tolerability (safety run-in part) of pembrolizumab plus platinum-based doublet chemotherapy with canakinumab and then the efficacy (double-blind, randomized, placebo controlled part) of pembrolizumab plus platinum-based doublet chemotherapy with or without canakinumab.
Olanzapine has been used as prophylactic antiemetic for chemotherapy induced nausea and vomiting. The project aims to evaluate the efficacy of olanzapine in combination with ondansetron and dexamethasone in patients at high risk of postoperative nausea and vomiting, with previous history of nausea and vomiting induced by prior chemotherapy, submitted to medium and large surgery.
The main purpose of this study is to compare myocardial injury of patients undergoing congenital cardiac defects repair surgery (RACHS Risk Score one, two or three) under total intravenous anesthesia compared to inhalation anesthesia with sevoflurane. The primary aim of the study is to evaluate the troponin I levels in patients following congenital heart surgery and elucidate if one of the two anesthetic techniques (TIVA x inhalation anesthesia) is more effective in reducing troponin I levels in the first 72h after surgery.. Sixty six are planned to be included in the study and the follow-up will take approximately 3 days for the primary outcome. As a secondary outcome evaluate the BNP, CPK and CKMB postoperative levels in the same period (72h), also ICU and hospital lengh of stay (LOS), duration of mechanical ventilation, inotropic/vasoactive drugs use and incidence of renal injury (according to pediatric RIFLE score).
