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.
Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and in infected patients, it produces symptoms which range from completely asymptomatic to those expressing severe illness. Early recognition of those developing severe manifestations allows for rapid and appropriate intervention, including admission to intensive care unit and intensive care therapy, such as mechanical ventilation. A current problem is that only limited data exist predicting the clinical course of COVID-19. This study will determine whether non-invasive urinalysis is useful in assessing and predicting the severity or clinical course of patients with COVID-19.
Trastuzumab is an important treatment for HER 2 positive breast cancer. But trastuzumab can cause injury to the heart, and this is one of the main reasons it cannot be administered as planned. Heart injury can often be successfully treated using cardiac medications. The objectives of SCHOLAR-2 are to evaluate whether is it safe and effective to continue trastuzumab, pertuzumab or trastuzumab-emtansine (T-DM1) in patients with early stage HER-2 positive breast cancer despite mild, minimally symptomatic or asymptomatic systolic left ventricular dysfunction as compared with a guideline-driven approach of withholding or discontinuing trastuzumab, pertuzumab or trastuzumab-emtansine (T-DM1). In SCHOLAR-2, we will compare two thresholds of withholding or discontinuing trastuzumab/pertuzumab/trastuzumab-emtansine: a threshold that is currently advocated for by existing treatment practice guidelines versus a more aggressive threshold that allows trastuzumab/pertuzumab/trastuzumab-emtansine to continue at lower levels of LVEF than currently supported by guideline documents.
Systemic autoimmune myopathies are rheumatic diseases that affect the striatum skeletal muscles. The transcranial direct current stimulation technique has been frequent, for example, in patients with ischemic stroke or for the optimization of muscular performance in athletes. However, to date, there are no studies evaluating this technique in patients with systemic autoimmune myopathies. Therefore, the main objective of the present prospective, randomized, double-blind, placebo-controlled study is to evaluate the safety and efficacy of the application of chronic transcranial direct current stimulation sessions - associated with aerobic exercises - in the patients with systemic autoimmune myopathies.
NEAT is an observational cohort (Prospective registry of real world data) of patients with coronary and peripheral artery disease in an outopatient setting.
The reason for this study is to determine if the study drug LY3471851 is safe and effective in adult participants with active ulcerative colitis (UC). The study treatment will last about 52 weeks.
The main objective of this study is to evaluate the efficacy of SZC as compared with placebo in keeping potassium levels within the normal range (3.5-5.0 mEq/L) while on spironolactone ≥25 mg daily without assistance of rescue therapy for hyperkalaemia (HK).
Short-course radiotherapy followed by consolidation chemotherapy has shown a better response rate when compared to chemoradiotherapy treatment. In addition, recent studies have shown better tolerance with total neoadjuvant treatment, with induction or consolidation chemotherapy. Induction chemotherapy could reduce the size of the tumor, treat micrometastases early and allow treatment to start immediately (avoiding potential delays in waiting for radiotherapy). While consolidation chemotherapy allows longer waiting times for surgery, with higher response rates.
This is a phase 3 study to compare the efficacy and safety of HBI-8000 or Placebo combined with nivolumab on patients with unresectable or metastatic melanoma and eligible patients who are not adolescents or patients with new, progressive brain metastasis will be stratified by PD-L1 expression and LDH level.
Background: Recent reports increasingly recognize neurological manifestations in COVID-19 patients. However, the full spectrum of the disease and risk factors are not well understood. Aim: To describe the full spectrum of neurological manifestations in COVID-19 and assess the clinical characteristics, risks and prognostic factors. Outcomes: Identification of COVID-19 associated neurological disease is the primary outcome while requirement for admission to critical care unit, mortality, length of hospital stay, quality of life, and neurological disability are the secondary outcomes. Participants: Patients above Age more than 18 years enrolled based on new-onset acute neurological disease and COVID19 positive will serve as cases while patient with confirmed COVID-19 without neurological manifestation will serve as controls. Design and Procedures: The study is prospective case control in design and is divided into three phases in India, Brazil and Malawi ; the first phase will address role of hypoxia in causation of neurological diseases, the second phase will compare characteristics of patients hospitalized with COVID-19 with and without neurological disease and the third phase will assess the long-term follow up (at 3 months and 9 months) of cases.
This is a randomized, multicenter, placebo-controlled, double-blind clinical study in patients hospitalized due to severe Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection.
