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.
To determine whether "continuous use" of celecoxib over a 6-month period is more efficacious than "usual or intermittent use" in preventing spontaneous osteoarthritis flares of the knee and hip.
A One Year Clinical Trial Assessing the Usefulness and Safety of Inhaled Insulin in Diabetics with Asthma
The main objectives of this study is to determine vaccine efficacy against severe rotavirus (RV) gastroenteritis (GE) during the period starting from 2 weeks after Dose 2 until one year of age.
The purpose of this study is to determine whether there is any additional benefit from abciximab administration during percutaneous coronary intervention in patients presenting with acute coronary syndromes after pre-treatment with 600mg of clopidogrel.
Tuberculosis (TB) is a serious infection that can affect the lungs and other parts of the body. The usual way to treat TB is to take 4 medicines by mouth every day for 2 months, then take 2 of the same medicines for 4 more months, for a total of 6 months. The purpose of this study is to see if taking 4 months of TB medicines is as effective in curing some TB patients as taking 6 months of TB medicines. Study participants will include 758 human immunodeficiency virus (HIV)-non-infected individuals, ages 18-60. Participants will be treated with 4 standard drugs called isoniazid, rifampicin, pyrazinamide and ethambutol. All individuals will take TB medicines for at least 4 months. After 4 months of treatment, if no TB germs are growing in sputum samples, participants will be assigned to either stop taking TB medicine (4 months of treatment) or to continue taking TB drugs for 2 more months (6 months of treatment). Participants will be involved in study procedures for up to 30 months.
The primary objective of this study was to compare the safety and efficacy of motavizumab to palivizumab when administered monthly by intramuscular (IM) injection for the reduction of the incidence of RSV hospitalization among children at high risk for serious RSV disease. A secondary objective was to compare the incidence of medically-attended lower respiratory infections (LRIs) between treatment groups.
Two groups of preterm infants with birth weight equal to or less than 1500 grams will be studied. One group will receive the standard care and the other will receive standard care plus maternal special tactile stimulation. Gain of weight, length and head circumference, date of the beginning of enteral feedings, length of time to recover birth weight and age of hospital discharge will be recorded and compared between both groups.
This study concerns the safety of blood transfusion. Prior to transfusion, staff should perform a number of essential safety checks to ensure that the correct patient is receiving the correct blood product. Evidence suggests that these safety checks are not always done. This study has been designed to assess the effect of a simple intervention on the performance of the bedside safety check. The hypothesis is that a simple intervention will improve the performance of the bedside check.
This trial is conducted in Asia, Europe, Middle East, North America, Oceania, and South America. The purpose of this study is to evaluate the treatment of Recombinant Factor VIIa (eptacog alfa (activated)) in patients with acute intracerebral bleeding. It is expected that more patients will recover without severe permanent disability after acute treatment with Recombinant Factor VIIa by reducing further intracerebral bleeding.
The purpose of the study is to determine the safety of and immune response to a DNA HIV vaccine followed by an adenoviral vector HIV vaccine in HIV uninfected adults.
