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 overall objective of this multisite, multicountry Zika in Infants and Pregnancy (ZIP) study is to assess the strength of the association between Zika virus infection (ZIKV) during pregnancy and adverse maternal/fetal outcomes and the risk of vertical transmission. The study will prospectively enroll a cohort of pregnant women up to 17 weeks and 6 days gestation and subjects at any gestational age with acute Zika infection, confirmed by serology or PCR (polymerase chain reaction) test. The study will follow these women through their pregnancy to identify for clinical evidence of acute ZIKV, while controlling for potential confounders. Outcomes in the women, the developing fetus, and infants will be assessed. All protocol-specified data will be recorded and entered in a central data management system for the purposes of analysis of composite data from the study.
This study evaluates the efficacy of Mirvaso® in the treatment of chronic persistent vascular facial erythema, after 4 weeks of treatment, by the Clinician erythema assessment.
The primary purpose of this study is to evaluate the efficacy of alogliptin 25 milligram (mg) once daily compared to placebo when administered as monotherapy, or when added onto a background of metformin alone, insulin alone, or a combination of metformin and insulin, as measured by the glycosylated hemoglobin (HbA1c) change from Baseline at Week 26 in pediatric participants with type 2 diabetes mellitus (T2DM).
The purpose of this study is to determine how patients with ovarian, fallopian tube, and primary peritoneal cancer will best respond to treatment with rucaparib versus chemotherapy.
Alpha-agonist in anesthesia display immunomodulatory effect in addition to antiadrenergic control. This effect of the immune system can be a key to a better perioperative safety and quality. The association of dexmedetomidine at general anesthesia adds up organic protection and inflammatory control to a surgery trauma owing to antinociception and immunomodulatory effect. The aim this study is evaluate if the association of dexmedetomidine at general anesthesia standing effective immunomodulatory control to trauma and improve changes at outcomes in patients undergoing to spinal fusion.
The purpose of this study is to assess the efficacy, safety, and pharmacokinetics of niraparib in men with metastatic castration-resistant prostate cancer (mCRPC) and deoxyribonucleic acid (DNA) repair anomalies.
In decompensation of heart failure, it may occur low cardiac output. For patients in this situation, the use of inotropic may be necessary. Prolonged intravenous infusion of inotropic agents can lead to phlebitis in peripherally venous access. On the other hand, central venous access presents complications inherent in the procedure. The peripherally inserted central catheter (PICC) may be an option in this situation. The present research project is a randomized clinical trial to evaluate the incidence of phlebitis by using the PICC in comparison to the peripheral venous access. The criteria for inclusion are: advanced congestive heart failure, in use of intravenous inotropic; platelets > 50.000 mm3 and left ventricular ejection fraction (LVEF) < 0.45. Patients will be randomized to receive the PICC or keep the peripheral venous access. The main outcome will be the occurrence of phlebitis. The sample size will be of 40 patients for each group (PICC and control). The data will be analyzed by logistic regression. Will be considered significant P 0.05.
Locally advanced cervical cancer at higher risk for recurrence (HRLACC) following concurrent chemotherapy and radiation therapy. This is a group of participants with a significant unmet need. The estimated probability of disease recurrence or death within 4 years of diagnosis is 50% and the prognosis is very grave for those who experience a recurrence. The purpose of the study was to compare the disease free survival (DFS) of ADXS11-001 to placebo administered following cisplatin-based combination chemotherapy and radiation (CCRT) with curative intent in participants with HRLACC.
National clinical trial, phase III, multicenter, single-arm, efficacy study, 80 participants of both sexes, aged equal or more than 12 and less than 65 years. The group will use Busonid® (budesonide 200mcg and 400mcg) one application (inhalation) of 200 mcg every 12 hours (400mcg / day). During follow-up visits if the participant has not shown an increase in forced expiratory volume in one second greater than 12% and greater than 0,20L or 200ml in spirometry compared with baseline visit, will increase the dose to 800 mcg / day (2x 400 mcg day). The study aims to revalidate by the National Health Surveillance Agency (ANVISA) the registration of the drug Busonid® which there is a vast scientific literature on the pre-clinical and clinical evidence that the efficacy and safety of budesonide. Thus, outlined is a single-arm study, which is applied to the study of the group of participants the same intervention for a certain period and the participants are evaluated for response.
The purpose of this study was to determine whether clonazepam and paroxetine are effective in the treatment of panic disorder. Efficacy was evaluated in short-term, long-term and post-treatment.
