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.
This is a randomized study that sought to compare the rule-out capacity and antibiotics prescriptions associated with two different diagnostic imaging strategies (ultra-low-dose chest computed tomography versus chest radiography) in a group of healthy adults presenting to the emergency department (ED) with suspected community-acquired pneumonia (CAP).
Long-term sequelae in TBI is a well-recognized burn. We designed a proof of concept study, randomized, double-blind, placebo-controlled to evaluate 36 adult TBI patients. To evaluate the early and late effects of 10 days of 20 minutes applying transcranial direct-current stimulation (tDCS) in the dorsolateral prefrontal cortex (DLPFC), bilateral temporal cortex (CTB) and compare to sham stimulation, and online cognitive training. We expect that the active group will differ from the sham group, showing larger effect sizes in the cognitive assessment.
The purpose of this study is in Part 1, to determine the safety of nivolumab, bempegaldesleukin (BEMPEG: NKTR-214), and Tyrosine Kinase Inhibitor (TKI) combination.
Phase III randomized clinical trial evaluating the sequencing of anthracyclines and taxanes in neoadjuvant therapy for locally advanced HER2-negative breast cancer.
More than five decades have passed since the identification of the etiologic agent of hepatitis B and yet this infection is a challenge for public health worldwide. The development and availability of the first hepatitis B vaccines, still in the 1980s, was a milestone for the prevention of the hepatitis B virus, and currently known as the gold standard strategy for the elimination of this infectious disease. In several countries, the introduction of the immunobiological occurred gradually, by age groups and risk groups, and in general, started with newborns and children. This universal immunization strategy has contributed to reducing the incidence and changing the epidemiological profile of HBV worldwide. At the beginning of the 21st century, it was already possible to shift the epidemiological curve of the infection to parasitize with 50 years or more. On the other hand, despite vaccination against hepatitis B being the most assertive tool for the prevention of HBV, the low performance of the vaccine in older groups remains a challenge for public health and the object of this study. To our knowledge, there are no data showing the efficacy of doses of enhanced hepatitis B vaccines for older adults, and the purpose of this study is to investigate and compare the immunogenicity of the hepatitis B vaccine in adult adults aged 50 years and over, using conventional doses (20μg) versus (vs) booster doses.
The purpose of the study is to demonstrate the safety and efficacy of the Merit WRAPSODY Endovascular Stent Graft for treatment of stenosis or occlusion within the dialysis access outflow circuit
DESTINY-Breast07 will investigate the safety, tolerability, and anti-tumour activity of trastuzumab deruxtecan (T-DXd) in combination with other anti-cancer agents in patients with HER2-positive Metastatic Breast Cancer
The purpose of this study is to compare the efficacy, as demonstrated by progression-free survival (PFS), in participants treated with amivantamab in combination with chemotherapy, versus chemotherapy alone in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) characterized by EGFR Exon 20ins mutations.
The aim of this study is to analyze if the use of oral antimicrobial solutions and dentifricies are able to reduce the SARS-CoV-2 load in the saliva and oral mucosa. It will be allocated hospitalized patients positive for SARS-CoV-2 (confirmed by RT-PCR of nasopharynx swab tests) and with signs and symptoms of COVID-19. These patients will be divided into two groups: patients enrolled in negative pressure rooms (NPR), and patients enrolled in intensive care units (ICU) with orotracheal intubation. These two groups will receive interventions with oral antimicrobial solutions or dentifrices, containing different compounds. Saliva and oral mucosa swabs will be collected before the intervention, immediately after the intervention, and after 30min and 1h. The primary outcome is to verify if these products can reduce the SARS-CoV-2 load in the saliva and oral mucosa at these time periods, detected by the measurement of the viral load and the fold-reduction.
The purpose of this study is to compare the safety and efficacy of the study drug tirzepatide to insulin lispro (U100) three times a day in participants with type 2 diabetes that are already on insulin glargine (U100), with or without metformin.
