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 objective of the study is to evaluate quantitative changes in mammographic breast density from baseline to 24 months in postmenopausal women receiving daily doses of either BZA 20 mg/CE 0.45 mg, BZA 20 mg/CE 0.625 mg, Raloxifene or placebo. The primary endpoint in this study is the change in mammographic breast density between baseline and month 24 for each group.
The purpose of this study is to investigate the association of adverse environmental factors, parental psychopathology, family functioning and genetic factors and the response to methylphenidate treatment in children and adolescents with Attention Deficit/Hyperactivity Disorder.
This 2 arm safety study will compare the outcome with respect to a composite endpoint of all-cause mortality and non-fatal cardiovascular events (myocardial infarction, stroke) in CKD participants either on dialysis or not receiving renal replacement therapy under treatment with methoxy polyethylene glycol-epoetin beta or reference ESAs. Participants will be randomized to receive intravenous (iv) or subcutaneous (sc) methoxy polyethylene glycol-epoetin beta at the following doses: for participants not already receiving ESA treatment, methoxy polyethylene glycol-epoetin beta will be administered at a starting dose of 0.6 micrograms per kilograms every 2 weeks (mcg/kg/2wks) iv or sc; for participants receiving maintenance ESA treatment, iv or sc methoxy polyethylene glycol-epoetin beta will be administered at an initial monthly dose of 120, 200 or 360 micrograms (mcg) depending on the weekly dose of ESA received prior to first methoxy polyethylene glycol-epoetin beta administration. Participants randomized to reference ESA treatment will receive iv or sc ESAs in accordance with their prescribed dosing information.
The investigators hypothesized that the group of patients receiving the medication interventions and CBT would show significant changes in their behavior, such as remission or reduction in anxiety, panic attacks, anticipatory anxiety, fear of body sensations, loss of control, and agoraphobia avoidance. And also, in the general evaluation of well-being, in the beginning and end of the treatment, in comparison to the control group (medication without CBT), during the same period.
This is a pharmacokinetic, descriptive, open-label, prospective, multicentric, national study in Aids and tuberculosis co-infected patients, to be laboratory and clinically monitored during the treatment with lopinavir-ritonavir and rifampin medications. Study population: Thirty patients older than 18 years, both male and female, which present active tuberculosis and failure or contraindication for any motive to an efavirenz will be selected to participate in the study. Objectives: - Evaluate the pharmacokinetics of lopinavir-800mg / ritonavir-200mg combination (every 12 h) in association with rifampin-containing anti-tuberculosis regimens, in patients presenting tuberculosis and HIV-infected with indication to antiretroviral treatment according to Brazilian Ministry of Health's guidelines, with contraindication to the use of NNTRI. - Describe the adverse events observed during the tuberculosis treatment period with rifampin associated with antiretroviral therapy consisting of lopinavir-800mg / ritonavir-200mg every 12 hours. - Describe clinical, immunological and virological endpoints throughout the study with these drugs.
180 women with genital prolapse will be submitted to genital prolapse surgical correction, half of them with human fascia, and the other half with Prolift.
The goal of this study is verify if the energy expenditure in preterm infant fed with human milk is different from preterm formula. A randomized, controlled, crossover, double blind clinical trial will be carried out in which the newborn will be its own control. Randomization will be according to the type of diet at the beginning of the study. Half of the participants will be randomly assigned to begin the study using one type of milk (for example, human milk) and later another type of milk (preterm infant formula) and the other half will do the opposite.
This study will compare PF-00299804 given orally on continuous schedule to the approved drug, erlotinib, in patients whose non-small cell lung cancer has progressed after chemotherapy; patients will be randomized to receive one of these drugs, and followed for efficacy and tolerance of each.
The purpose of this study is to determine whether patients with obstructive sleep apnea have any changes in left ventricular function and structure after 06 months of continuous positive airway pressure treatment.
The purpose of this study is: 1. To determine the frequency of cardiovascular diseases in patients with OSA, obese, overweight, and lean (BMI<25) 2. To analyze the CPAP treatment over the clinical evolution of OSA patients 3. To determine if OSA is a independent predictor of cardiovascular risk
