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 purpose of this trial is to assess the efficacy, safety and tolerability of lacosamide administered as add-on therapy with 1 to 3 anti-seizure medications. This trial is for children aged 1 month to less than 4 years with epilepsy who currently have uncontrolled partial-onset seizures.
Na-GST-1 and Na-APR-1 are proteins expressed during the adult stage of the Necator americanus hookworm life cycle that are thought to play a role in the parasite's degradation of host hemoglobin for use as an energy source. Vaccination wtih recombinant GST-1 or APR-1 has protected dogs and hamsters from infection in challenge studies. This study will evaluate the safety and immunogenicity of co-administering Na-GST-1 and Na-APR-1 to healthy Brazilian adults living in an area of endemic hookworm infection.
Intervention studies do not account for high within-individual variation potentially compromising the magnitude of an effect. Repeat administration of a treatment allows quantification of individual responses and determination of the consistency of responses. The investigators aim to determine the consistency of metabolic and exercise responses following repeated administration of sodium bicarbonate (SB). Design and Methods: 15 physically active males will complete six cycling capacity tests at 110% of maximum power output (CCT110%) following ingestion of either 0.3 g∙kg-1Body Mass of SB (4 trials) or placebo (PL, 2 trials). Blood pH, bicarbonate, base excess and lactate will be determined at baseline, pre-exercise, post-exercise and 5-min post-exercise. Total work done (TWD) will be recorded as the exercise outcome.
The effects of phototherapy has been widely studied by some research groups. The investigators know that there are positive results with light application to improve muscle performance and delay fatigue. However, there are few studies showing its´ effects on muscular training. Therefore, the aim of this study was to assess the effects of phototherapy applied at different times during 12 weeks of strength training. For such, 48 volunteers, healthy male, from 18 to 35 years old were recruited to perform a strength training protocol for the anterior muscle of the thigh development. Volunteers performed the training protocol twice a week for 12 weeks. There were assessed isometric peak torque in isokinetic dynamometer, 1-repetition maximum test in the leg extension and leg press machines and bilateral thigh perimetry.
To clinically evaluate the treatment of mandibular class II furcation defects with enamel matrix derivative (EMD) and/or a bone substitute graft make of beta tricalcium phosphate/hydroxyapatite (βTCP/HA).
The aim of this study is to assess the efficacy and safety of single agent AZD9291 in a real world setting in adult patients with advanced or metastatic, epidermal growth factor receptor (EGFR) T790M mutation-positive Non-Small Cell Lung Cancer (NSCLC), who have received prior EGFR-tyrosine kinase inhibitor (TKI) therapy.
The present study aims to evaluate the impact of detecting active initial caries lesions in primary teeth regarding effectiveness, cost-effectiveness, applicability (acceptability and satisfaction) and quality of life. For this, 248 children 3-6 years with complete primary dentition will be examined and treated in a mobile dental unit, which will temporarily be parked in public schools of Sao Paulo. The caries detection will be conducted using the International Caries Detection and Assessment System (ICDAS) and, depending on allocation, an adjunct criterion for caries activity assessment. Children will be randomized in two groups according to the caries threshold to be detected: Group A (only advanced lesions will be detected and treated, independently of their activity status) and Group B (all caries lesions, including initial ones, will be detected and all active lesions will be treated). After this, the treatment plan for each child will be made according to strategies mentioned above. Data concerning the cost-effectiveness of the procedures, acceptability / satisfaction of children and quality of life will be collected after diagnosis, after the end of treatment and 12 and 24 months from the initial examination. For comparison between groups, multilevel regression analyses will be performed. The primary outcome will be sites which need of operative treatment during the follow-up periods and the secondary outcomes will be the cost-effectiveness of each strategy, the acceptability / satisfaction of the child and the impact on quality of life.
A multicenter, double-blind, randomized, parallel-group, Phase III study of the efficacy and safety of Hercules( Myl 1401O, Mylan Trastuzumab) plus taxane versus Herceptin® plus taxane as first line therapy in patients with HER2-positive metastatic breast cancer.
In the past few years, studies have evaluated the effect of systemic use of sodium alendronate, especially in the treatment of structural bone defects caused by periodontal diseases. This study evaluated the effects of non-surgical periodontal treatment associated with the topical application of 1% sodium alendronate on clinical and topographical parameters. Chronic periodontitis patients were recruited for the present study and were monitored at 3 and 6 months after baseline examinations. A placebo gel was used as control.
This study aims to assess whether there is change in the growth and development of newborns whose mothers will have a etonogestrel (ENG) releasing implant inserted in the first 24 to 48 hours of delivery compared with those with standard implant insertion (6 week postpartum).
