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 purpose of this study is to determine if the isoniazid is effective in the prevention of tuberculosis in a prison population, exposed to the high endemicity of the disease.
This is a Phase III, multicenter, randomized, placebo-controlled, double-blind study to evaluate the efficacy and safety of atezolizumab versus placebo in participants with RCC who are at high risk of disease recurrence following nephrectomy.
This is a prospective, multicenter, non-randomized registry/observational study. The study will enroll up to 200 patients with successful St. Jude Medical (SJM) Cardiac Resynchronization Therapy (CRT) MP device implant from up to 10 centers.
Introduction: Recently sphenopalatine block emerged as an alternative to epidural blood patch for post dural puncture headache but the investigators do not know if it has significant efficacy when compared to epidural blood patch. Method: randomized trial where patients will randomly receive either sphenopalatine block or epidural blood patch. Pain relief to no pain or low intensity pain will be the main outcome
Synthetic phosphoethanolamine is a primary amine which has a critical role in the biosynthesis of cell membranes. Pre-clinical models have shown potential anticancer activity.
The purpose of this study is to characterize the Pharmacokinetic and to confirm the popPK model derived from healthy volunteers in hospitalized adults who are infected with respiratory syncytial virus (RSV) and to determine in adults who are hospitalized with respiratory syncytial virus (RSV) infection the dose response relationship of multiple regimens of lumicitabine on antiviral activity based on nasal RSV shedding using quantitative real-time reverse transcriptase-polymerase chain reaction (qRT-PCR) assay.
The primary objective of Part 1 of the study is to determine if BIIB093 improves functional outcome at Day 90 as measured by the modified Rankin Scale (mRS) when compared with placebo in participants with Large Hemispheric Infarction (LHI). The secondary objectives of Part 1 of the study are to determine if BIIB093 improves overall survival at Day 90 when compared with placebo, if BIIB093 improves functional outcome at Day 90 on the mRS dichotomized 0-4 vs. 5-6 when compared with placebo, if BIIB093 reduces midline shift at 72 hours (or at time of decompressive craniectomy [DC] or comfort measures only [CMO], if earlier) when compared with placebo, and to evaluate the safety and tolerability of BIIB093 in participants with LHI. The objectives of Part 2 of the study are to evaluate long-term disability following LHI, to evaluate long-term outcome measures of clinical function, quality of life, and healthcare utilization, and to assess the safety of BIIB093 in subjects with LHI during the follow-up period.
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.
Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
The use of antiretroviral therapy (ART) could prevent depression of the immune system of patients harboring with Human Immunodeficiency Virus (HIV), providing increased life expectancy, changing the classification of HIV / AIDS into a chronic illness. However prolonged use of ARTincreases the prevalence of lipodystrophy syndrome (SL), characterized by inadequate distribution of body fat and changes in lipid profile, associated with a significantly increased cardiovascular risk, among others. The practice of strength training (ST) helps in controlling SL, providing improved lipid profile and the quality of life of these patients. However, due to increased cardiovascular risk and physical weakness resulting from SL, the ST with vascular occlusion (STOV) could be a viable alternative training, to use low load (10-30% of maximal work capacity) with similar benefits ST traditional (STT), as already proven in other populations. The STOV is justified by the lower neuromuscular overhead, increasing the number of patients able to participate in this complementary therapy. The objective was to assess the impact of the combined strength training with vascular occlusion on SL and the skeletal muscle tissue in people harboring with HIV/Aids.
