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 Phase 2, randomized, double-blind, placebo-controlled, multicenter study of ALXN2050 (120 and 180 milligrams [mg]) in addition to background therapy consistent with the standard of care in adult participants (≥ 18 to ≤ 75 years of age) with either LN or IgAN. The study will consist of an up to 6-week Screening Period, a 26-week blinded Initial Evaluation Period, a 24-week blinded Extended Treatment Period, and an Open-label Extension (OLE) Period of up to 2 years. Safety will be monitored throughout the study.
Dietary supplementation with methyl donors has been demonstrated to increase DNA methylation in leucocytes whereas a limited dietary intake of methyl donors was associated with DNA hypomethylation. Considering SLE disease, previously study showed that high doses of vitamin B6 and folate were associated with less severe SLE. Furthermore, some evidences reported a relatively high incidence of decreased serum B12 levels in rheumatic patients. This led to the suggestion that diets rich in methyl group donors could have beneficial effects on SLE.
This is an interventional, randomized, parallel group, treatment, Phase 3b/4, double blind, 2-arm study to assess the effect of dupilumab compared to standard of care therapy on preventing or slowing the rate of lung function decline in adult patients with uncontrolled moderate to severe asthma. The estimated duration is 4±1 weeks of screening and run-in period, followed by a 3-year double blinded treatment period. There will be a post-treatment follow-up (FU) period up to 12 weeks.
The present study is a clinical intervention applied to patients with urinary incontinence, with the intention of verifying the effects of the Pilates method associated or not with photobiomodulation with static magnetic field. The sample will consist of women with stress urinary incontinence from Bento Gonçalves attended at the school clinic of Faculdade Cenecista de Bento Gonçalves.
This is an observational study carried out in Brazil in patients with P. vivax malaria. The study will be carried out in the municipalities of Manaus (state of Amazonas) and Porto Velho (state of Rondônia). G6PD and TQ tests will be provided to health facilities by municipal health authorities using the common route for the provision of drugs and diagnostics. PQ and other antimalarial drugs are already available in Brazil. Designated personnel at the health facilities will be trained to perform the G6PD quantitative test procedure and the radical healing treatment algorithm by the Lead Researcher (RP) team and municipal authorities using teaching materials developed by the sponsors. The study design is based on the secondary use of data routinely collected from all malaria patients in the Epidemiological Surveillance Information System for Malaria (SIVEP-Malaria) by the Ministry of Health (MS). Data from all malaria patients are routinely collected through SIVEP forms by health professionals (HP) and entered into the SIVEP database by the municipality staff. The SIVEP form will be adapted by the MS to collect information about the G6PD test, TQ treatment and signs of hemolysis. The retrospective data from all patients will be entered into a new database by the municipality staff during the study period and the relevant data will be automatically exported weekly to the SIVEP database. The study team will only have access to unidentified data, according to the access levels that will be assigned to each member in the system. Only the municipality's team will have access to the identified patient data. In addition to the data collected on the SIVEP forms, the PR team will ask the two referral hospitals that routinely receive all admissions due to AHA to perform a regular screening of electronic hospital admission records for patients with signs of AHA (renal failure, jaundice, blood transfusion, malaria). All identified cases will be investigated using hospital records and SIVEP forms. Confirmed information about drug-induced AHA will be linked to the patient record recorded in the database. The PR team will also contribute to pharmacovigilance training. Physicians at tertiary-level health units will report side effects through the VigiMed system, from the National Health Surveillance Agency (ANVISA).Finally, the additional costs of implementing the G6PD and TQ tests will be collected along with the study at the health facilities. Since the study is based on retrospective data collection, and the adoption of TQ and G6PD testing will be done by the municipality, the G6PD testing and the treatment of patients with TQ or PQ will be carried out in accordance with the treatment policy , that is, regardless of the study. The study will be carried out in phases: - 1st phase (approximately 3 months): Training and provision of G6PD and TQ tests will initially be limited to 10 high-complexity and intermediate-complexity units (referral hospitals, hospitals, emergency care units, polyclinics). Data will be collected from patients with P. vivax treated at these health facilities. An interim analysis will be performed after collecting data from 600 patients with P. vivax ≥ 16 years, who have not been treated for vivax malaria in the past 60 days, in the study database in order to decide whether the study can be extended to less complex health units. The decision will be made by an Independent Study Oversight Committee (ISOC). If the interim results of Phase 1 are found to be unsatisfactory, ISOC may decide not to extend the study to primary care units until improvements in the educational program are implemented and/or additional support is provided to health professionals. Additional interim analyzes will be performed as appropriate. - 2nd phase (approximately 9 months) [CURRENT PHASE]: if approved by ISOC, the study will be extended to less complex health units (basic health units, family health units and other primary care services) and other high and medium complexity of health in the selected municipalities. After staff training, G6PD and TQ testing will be provided to these health facilities by municipal health authorities. During this 2nd phase, data will continue to be collected from patients with P. vivax treated by the 1st phase tertiary care units. - An additional interim analysis will be performed after data from 600 patients with P. vivax ≥16 years old, who have not been treated for P. vivax malaria in the past 60 days, from primary care units are collected in the study database ( approximately 3 months after the start of the 2nd phase). The study will continue while the interim analyzes are being carried out. Final results will be analyzed and validated by ISOC. The study is expected to take approximately 15 months.
The purpose of this study is to evaluate the efficacy and safety of vericiguat in participants with chronic heart failure with reduced ejection fraction (HFrEF), specifically those with symptomatic chronic HFrEF who have not had a recent hospitalization for heart failure or need for outpatient intravenous (IV) diuretics. The primary hypothesis is that vericiguat is superior to placebo in reducing the risk of cardiovascular death or heart failure hospitalization.
Hypotension is a common complication of intermittent renal replacement therapy. Methylene blue, an inhibitor of nitric oxide synthesis, has been suggested to improve hemodynamics during renal replacement therapy in ambulatory patients, but evidence is lacking for critically ill patients. This trial will assess whether methylene blue can improve hemodynamics and blood pressure for patients with shock requiring renal replacement therapy.
Rapid-sequence intubation is routinely performed in critically ill patients. It is unclear whether different sedative agents may influence short-term outcomes after intubation, specially hemodynamic stability.
Early diagnosis of LC in the asymptomatic stage through intentional screening programs and/or incidental pulmonary nodule identification and follow-up are known to improve outcomes significantly. There are large gaps in the screening and early detection of LC, especially in LMIC - driven by multifactorial aspects, including a variety of socioeconomic and infrastructural factors, mainly due to limitations in the required network of specialized human resources and technical capacity. Identifying LC at an early stage allows for treatment that is more likely to be curative, thereby improving survival. The present study aims to characterize the lung nodule journey in different hospitals/clinics across Latin America, describing the use of health resources, time to diagnosis, stage at diagnosis, and time to treatment depending on the source of nodule identification in two different cohorts (retrospective and prospective).
This Phase 2, Randomized, Double-Blind, Placebo-Controlled Study is intended to evaluate the Efficacy, Safety, and Tolerability and PK of INCB000928 administered to participants with a clinical diagnosis of fibrodysplasia ossificans progressiva (FOP).
