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.
This was a long-term, open-label study of the safety, tolerability and effectiveness of RP103 in cystinosis patients who were naïve to any form of cysteamine treatment. Participants received RP103 treatment for at least 12 months. U.S. participants transitioned to the commercially approved drug PROCYSBI®. In Brazil, after at least 12 months of study participation and upon approval by the Brazilian regulatory authorities, participants were eligible to transition to a post-study drug supply program, and continue to receive the drug at no personal cost.
A study to research whether subconjunctival bevacizumab injection may potentially suppress neovascularization in pterygium, retarding and decreasing the size of recurrent pterygium.
This a multi-center study to examine whether supplementation with omega 3 fatty acids will reduce seizure frequency in patients with epilepsy .
Left ventricle diastolic dysfunction (LVDD) is associated with resistant hypertension. In addition, brain natriuretic peptide (BNP) levels are elevated when LVDD is present. It has been shown that phosphodiesterase-5 (PDE5) inhibition improves left ventricle diastolic function in hypertensive rats, despite any difference in blood pressure levels. Also, left ventricle diastolic function enhancement reduces BNP concentration in hypertensive patients. However, it is unknown if these effects exists in humans with resistant hypertension. Therefore, this study was developed to evaluate if the use of a PDE5 inhibitor (tadalafil) for 2 weeks improves LVDD and its effects in BNP levels in resistant hypertensive patients.
To evaluate corneal sensitivity changes following corneal cross-linking (CXL) in patients with progressive lower stage keratoconus.
This study aims to evaluate pulmonary function and respiratory muscle strength in a group of elderly women with hypertension before and after a respiratory muscle training.
Anesthesia of the soft and hard tissues in the maxilla may require up to five injections. Thus, the aim of the present study was to evaluate the anesthetic efficacy in buccal tissues after the use of the anterior middle superior alveolar (AMSA) and supraperiosteal techniques during subgingival scaling and root planning (SRP).
The purpose of this project is to determine the effectiveness of an eyewash osmoprotective lubricant comparing to castor oil containing and non-osmoprotective lubricants in different types of DTS and post refractive surgery patients.
Experimental studies suggest that anti-inflammatory and immunomodulatory drugs could reduce the inflammatory profile in acute ischemic disease and reduce the area of ischemia. Methotrexate is a drug that has shown promise in ischemic disease in animal studies.
The objective of this work was to compare the effects of two balance training programs, one Nintendo Wii Fit-based and the other traditionally-based without the use of a gaming system, on the (1) balance, (2) gait, (3) functionality and (4) cognition ability in older adults. It is a prospective, single blinded, randomized clinical trial performed at Center of Research of the courses of Speech Therapy, Physical Therapy and Occupational Therapy of São Paulo University. Thirty-two older adults are randomly in control and experimental group, 16 each one. The study includes only participants scoring at least 24 in the Mini-Mental State Examination to rule out effects of dementia; without the presence of depression, according to the Geriatric Depression Scale of Yesaváge - version 15 (GDS-15 ≤ 5) and scores on the Berg Balance Scale (EBB ≥ 41).
