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.
Parkinson's disease is a progressive, degenerative neurological disease associated with profound changes in the quality of life of its survivors. Therapeutic exercises are widely employed in the attempt to delay or minimize disease progression, characterized by significant motor and sensory deficits. Recent evidence has demonstrated the potential use of transcranial direct current stimulation (TDCs) as a complement to therapeutic exercises. However, few studies have investigated the effects of TDCs combined with therapeutic exercises in patients with Parkinson's disease. This study aims to investigate the effect of TDCs combined with therapeutic exercises in people with Parkinson's disease. Thirty patients will be randomized into two distinct groups to receive either TDCs(anodal) + therapeutic exercises or TDCs (sham) + therapeutic exercises for 24 sessions over a five-week period. The primary clinical outcome (balance) and secondary outcomes (functional capacity, quality of life and perception of overall effect) will be collected before treatment after two and five weeks at month 3 and month 6 after randomization. The data will be collected by a blind examiner to the treatment allocation.
This is a phase 3, multicenter, double-blind, randomized, placebo-controlled, parallel-group study to evaluate the efficacy and safety of CSL112 on reducing the risk of major adverse CV events [MACE - cardiovascular (CV) death, myocardial infarction (MI), and stroke] in subjects with acute coronary syndrome (ACS) diagnosed with either ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI), including those managed with percutaneous coronary intervention (PCI) or medically managed.
Clinical non-inferiority study between Diosmin 600 mg tablets and Diosmin 900 mg + Hesperidin 100 mg tablets in symptomatic chronic venous insufficiency after 6 months of treatment. Prospective, single-blind, randomized study in parallel groups (total patient population 120, 60 subjects per treatment group), with a total of 4 clinical assessment at months 0, 2, 4, and 6 of treatment.
Prospective, multicenter, single arm registry to monitor post-market clinical outcomes of patients treated with Inspiron Sirolimus-Eluting Stent with Biodegradable Polymer.
This study analyse the impact of high protein intake associated to early programed exercise on functional outcomes of adult intensive care patients.
To develop and validate a specific questionnaire of sexual quality of life in several languages and cultures (France, Brazil, Australia) allowing a meaningful and comprehensive assessment of the sexuality of patients infected with HIV and HCV; Propose reference scoring for sub-populations.
This study was designed to compare 3 immunosuppression regimens: sirolimus and tacrolimus versus everolimus and tacrolimus versus mycophenolate and tacrolimus. The primary outcome is the incidence of cytomegalovirus infection / disease, a relevant medical need in the absence of pharmacological prophylaxis.
Soil-transmitted helminths (STHs) are a group of parasitic worms that infect millions of children in sub-tropical and tropical countries, resulting in malnutrition, growth stunting, intellectual retardation and cognitive deficits. To control the morbidity due to these worms, school-based deworming programs are implemented, in which anthelminthic drugs are administered to children without prior diagnosis. The continued fight against these worms is aided by the London declaration on neglected tropical diseases, which helps sustain and expand global drug donation program, resulting in an unprecedented growth of deworming programs. However, the high degree of drug pressure makes deworming programs vulnerable to the development of anthelmintic resistance because they only rely on one drug with sometimes suboptimal efficacy and there is no availability of alternative drugs. Moreover, at present, there is no surveillance system to monitor the emergence and spread of anthelmintic resistance. It remains unclear to what extent the efficacy of drugs may have dropped and whether anthelmintic resistance is already present. This project aims to strengthen the monitoring and surveillance of drug efficacy and anthelmintic resistance in STH programs. As such, it will support deworming programs in their quest to eliminate STHs as a public health problem. The specific objectives of the first work package are to validate diagnostic tools to monitor drug efficacy and the spread of anthelmintic resistance, and to validate molecular markers for benzimidazole resistance. This study will be conducted at four different sites (Ethiopia, Tanzania, Lao PDR and Brazil) and will focus on school-aged children (age 5-14). At baseline subjects will be asked to provide a recent stool sample which will be processed using 3 different microscopic techniques (KK, Mini-Flotac and FECPAKG2). All children will be treated with a single-oral dose of albendazole (ALB) 400 mg and 14-21 days after treatment, a second stool sample will be collected from all children to again determine the fecal egg counts. At each sampling, stool is stored in preservative. Stored stool will be shipped to Belgium for DNA extraction and quantitative PCR (qPCR) analysis. A subset of the samples will be analysed by pyrosequencing to evaluate the single nucleotide polymorphisms in the b-tubulin gene. Pooling of the stored samples will also be performed to compare with the values obtained from analysing individual samples.
Physical exercises proves to be an option to revert a vicious cycle and aggravation of the painful that chronic low back pain can provide, which can improve the mobility and stabilization of the spine, muscle strength, motor coordination and general aerobic conditioning. In addition, photobiomodulation using light emitting diodes (LEDs) has attracted attention for acute and chronic pain and wound healing, being used as a resource for prevention and recovery of lesions. Thus, the present study aims to analyze the efficacy of aerobic training systematized with Deep Water Running associated with photobiomodulation in individuals with chronic nonspecific low back pain. Individuals of both sexes, sedentary, who present chronic low back pain, aged between 30 and 55 years (middle-aged individuals) who meet the inclusion and exclusion criteria will be invited to participate. Anthropometric measurements, maximal stress test, functional tests, physiological measures and questionnaires concerning disability and pain, besides psychological ones, will be carried out. After the evaluations, the participants will be randomized into three experimental groups with 15 participants in each: the first group will be the training group that will hold interval training sessions in addition to continuous training sessions (GT). The second group will perform the same training model, and before the training sessions the LED will be applied (GTL). And the third group will only receive the LED application (GL).
The purpose of this study is to compare the efficacy of treatment with ustekinumab or adalimumab in biologic naive participants with moderately-to-severely active Crohn's disease (CD) who have previously failed or were intolerant to conventional therapy (corticosteroids and/or immunomodulators, such as azathioprine, 6-mercaptopurine, or methotrexate), as measured by clinical remission at one year.
