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.
RADICAL PC1 is a prospective cohort study of men with a new diagnosis of prostate cancer. RADICAL PC2 is a randomized, controlled trial of a systematic approach to modifying cardiovascular and lifestyle risk factors in men with a new diagnosis of prostate cancer.
This Phase III study will compare the efficacy and tolerability of a Fixed Dose Combination of Etodolac + Cyclobenzaprine versus the isolated drugs in postoperative pain control after impacted third molar extraction.
To determine whether the implantation of an intrastromal corneal ring is an effective treatment for a homogeneous group of mild keratoconus patients.
For the non-surgical treatment of distal radius fractures in adults a variety cast options are available, including or not the elbow joint. The literature is inconclusive regarding the need to immobilize the elbow joint after reduction of the distal radius fracture.This study was undertaken to evaluate the best method of immobilization between the above and below-elbow cast groups at the end of 6 months of follow-up.
This Phase 3, multicenter, randomized, double-blind, placebo controlled study is designed to evaluate the efficacy and safety of atezolizumab (MPDL3280A, an anti-programmed death-ligand 1 [PD-L1] antibody) administered in combination with paclitaxel compared with placebo in combination with paclitaxel in participants with previously untreated, inoperable locally advanced or metastatic, centrally confirmed TNBC. Participants will be randomized in a 2:1 ratio to receive atezolizumab or placebo plus paclitaxel until disease progression or unacceptable toxicity or end of study, whichever occurs first (maximum up to approximately 40 months). In addition, the Sponsor may decide to terminate the study at any time.
The purpose of this study is to test an educational program with telephone follow-up to improve health-related quality of life (HRQoL), treatment adherence, and reduce anxiety and depression symptoms in patients who are starting oral anticoagulants (OA).
The purpose of this phase I study is to know the pharmacodynamic profile in in intravenous application in humans of the sodium heparin of porcine origin of the company União Química, building from the pharmacodynamic data generated its pharmacokinetic profile, due to the dosage limitation of heparin directly in biological samples. In addition, the toxicity of the product will be evaluated in healthy male participants.
The aim of the present study is analyze the effects of combined training program (resistance and aerobics) in comparison with a non-training group on quality of life, as well as on neuromuscular and cardiorespiratory parameters in breast cancer patients in stages one to three who have finished their treatment, such as surgery, chemotherapy and radiotherapy. Therefore, 42 women will be randomly divided into two groups: combined training group and control group. The subjects of the combined training group will undergo the intervention three times a week for eight weeks. The combined group will carry out both resistance and aerobic exercises in the same session. The resistance training will be comprised by ten exercises which will alternate body segments with maximum repetitions in the first set and the lower limit of the repetitions interval in the next sets. Along the training, the number of series will be increased whereas the number of repetitions will be decreased. The intensity of the aerobic exercises will be based on the percentage of the heart rate of the anaerobic threshold on the first weeks and on the speed of the anaerobic and aerobic threshold on the last weeks. Before and after the intervention, there will be evaluation of maximal dynamic strength of knee extensors and elbow flexors, maximum voluntary isometric contraction of knee extensors, maximum muscular activity of vastus lateralis and rectus femoris, muscle thickness of knee extensors, peak oxygen uptake and ventilatory threshold, quality of life and cancer-related fatigue. Data will be analyzed by Generalized Estimating Equations (GEE) and Bonferroni's post-hoc (α=0,05), including both protocol and intention to treat.
No drug treatment is completely free of risk and lack of response, adverse events and poor adherence may affect its effectiveness. Within this context, this project aims to evaluate the importance of monitoring blood levels and salivary drug used in rheumatic autoimmune diseases in the monitoring of adherence to therapy. In addition, this project intends to use the monitoring of drug levels, based on pharmacokinetic studies and pharmacokinetics/pharmacodynamics modeling, to broaden the understanding of the possible cellular, tissue and immunological mechanisms involved in efficacy and adverse effects of these drugs with the prospect of reducing the damage and maintain therapeutic efficacy. The high-performance liquid chromatography (HPLC) coupled to mass spectrometry, which will be used to evaluate hydroxychloroquine, thalidomide, glucocorticoids, is considered the gold standard technology to qualitative and quantitative analysis of drugs in blood and its comparison with the dosage in the saliva is an improvement in simplification of the process. For biological agents the focus will be on the understanding the loss of efficacy and the possible role of anti-TNF antibodies using ELISA capture methodology.This project will be divided into four sections with their respective sub-projects according to the medications that will be studied: hydroxychloroquine, thalidomide, biologic agents and glucocorticoids.
Introduction: Expiratory flow limitation (EFL) and ventilatory inefficiency during dynamic exercise have been identified in patients with recent myocardial infarction (RMI) with preserved ventricular and pulmonary function. However, it is not known what is the prevalence of EFL in this population and what are the effects of physical and respiratory training on this limitation. Objectives: To evaluate the prevalence of EFL and ventilatory inefficiency during dynamic exercise in individuals with uncomplicated RMI, and to evaluate the effects of interval physical training (IT) in addition to inspiratory muscle training (IMT), exclusive IT and absence of cardiopulmonary rehabilitation (CR) on EFL and ventilatory efficiency. Methods: 54 patients will be included, divided into three groups with 18 participants each. All will be submitted to evaluations of heart rate variability, hematological and biochemical profile, erythrocytes membrane deformability and stability, inflammatory markers, respiratory pressures, plethysmography, spirometry, carbon monoxide diffusion capacity, ankle brachial index, electrical bioimpedance, echocardiogram, quality of life questionnaires, cardiopulmonary exercise testing and constant load tests. Then, groups 1 (IT) and group 2 (IT + IMT) will participate in a physical training program for 12 weeks and will be re-evaluated after this period. In addition, they will be monitored for a 6 month period after discharge, with returns every two months to measure the energy expenditure through an accelerometer, and at the end of this period they will repeat all the tests again. Group 3 (absence of CR), will consist of patients who do not live in the city or those who can not participate in the CR program for any other reason, and will only participate in the evaluations.
