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.
Subjects referred for a routine CTA (computed tomography angiography) or MRA (magnetic resonance angiography) will be invited to participate in the study and subjects will be involved in the study for between 2 and 12 days. Two to three visits to the study doctor will be required. This study will compare the diagnostic results of Gadobutrol enhanced MRA images with MRA images taken without contrast agent using images from a CTA as the standard of reference, which may have been performed up to 60 days prior to enrolment. If a CTA has not been performed in this prior time period, a CTA is required for the study. MRA and CTA images will be collected for an independent review (blinded read).
The purpose of this study is to determine the clinical and radiologic implications of the intraoperative microemboli during carotid revascularization.
The purpose of this study is to evaluate whether overall survival for the trabectedin group is superior to the dacarbazine group for patients with advanced L-sarcoma (liposarcoma or leiomyosarcoma).
The purpose of this study is to determine whether BA058 (abaloparatide), a parathyroid hormone-related peptide, is effective in preventing fractures in postmenopausal women with severe osteoporosis who are at risk of fractures.
The purpose of this study is to determine whether inexpensive, flexible and non-heeled footwear is effective in improving of clinical, functional and gait biomechanics in elderly women with knee osteoarthritis.
The purpose of this study is to compare the effects of a balance reeducation protocol and an evidenced based protocol on pain, function and postural control of low back pain patients.
The purpose of this study is to elaborate an educative program that includes telephone follow-up and assess its impact on the perceived health status of patients submitted to percutaneous coronary intervention.
To determine the Chamomilla recutita solution dose needed to reduce the intensity and evolution time of oral mucositis in adult subjects submitted to HSCT.
The study investigated 100 subjects, both genders, with chronic Chagas disease, confirmed by at least two distinct serological tests, and classified according to Los Andes classification in a long term follow-up aiming at identifying the predictive value of the signal-averaged electrocardiogram for cardiac death and ventricular tachycardia. All subjects admitted to the study were submitted to clinical history taking, physical examination, and noninvasive assessment, including blood pressure measurement, resting 12-lead surface electrocardiogram, 24h ambulatory electrocardiogram monitoring, M-Mode/two-dimensional echocardiogram, signal-averaged electrocardiogram in both time and frequency domains. Selected subjects were further submitted to treadmill stress test and coronary angiography to rule out coronary heart disease. Subjects were followed by non-investigational primary care assistance at three to six months scheduled clinical visits on an outpatients basis. Both noninvasive and invasive evaluation during follow-up were requested at discretion of primary evaluation. Adverse outcomes were ascertained by review of medical records and active contact to either study subjects or their relatives.
The aim of this study is to compare the efficacy of super-LED reverse phototherapy with the fluorescent reverse phototherapy in term and late preterm newborns.
