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 objectives of this study are to evaluate the safety, tolerability, antiviral activity and efficacy of AT-527 in adult subjects ≥18 years of age with moderate COVID-19 and risk factors for poor outcomes (such as obesity (BMI>30), hypertension, diabetes or asthma). Eligible subjects will be randomized to blinded AT-527 (nucleotide analog) tablets or matching placebo tablets to be administered orally for 5 days. Part A will evaluate an AT-527 dose of 550 mg BID and Part B will evaluate a second dose of AT-527 (1100 mg BID). Local supportive standard of care (SOC) will be allowed for all subjects. Efficacy, antiviral activity and safety observations will be compared for treatment with active AT-527 tablets vs. placebo tablets.
A phase 2/3, randomized, double blind, placebo-controlled study to evaluate the efficacy and the safety of ABX464 in treating inflammation and preventing acute respiratory failure in patients aged ≥65 and patients aged ≥18 with at least one additional risk factor who are infected with SARS-CoV-2 (the MiR-AGE study).
This is a double-blinded, randomized control trial to assess the efficacy and safety of anti-SARS-CoV-2 convalescent plasma as early treatment. Participants will be randomized 2:1 to receive either convalescent plasma qualitatively positive for SARS-CoV-2 antibody ("anti-SARS-CoV-2 plasma") or control (albumin 5%). This study will investigate the potential of convalescent plasma (CP) to reduce severity of and/or help treat SARS-CoV-2 disease in patients with mild disease.
This study compare the efficacy and safety of tocilizumab versus methylprednisolone in the cytokine release syndrome of patients with COVID-19
This is an open-label, multicenter, rollover study to evaluate the safety, tolerability, and efficacy of long-term administration of open-label gantenerumab in participants with AD who completed Study WN29922 or WN39658, either the double-blind or open-label extension (OLE) part.
There is currently no treatment available for COVID-19, the acute respiratory illness caused by the novel SAR-CoV-2. Convalescent plasma from patients who have recovered from COVID-19 that contains antibodies to the virus is a potential therapy. On March 25th, 2020, the FDA approved the use of convalescent plasma under the emergency investigational new drug (eIND) category. Randomized trials are needed to determine the efficacy and safety of COVID-19 convalescent plasma for acute COVID-19 infection. The objective of the CONCOR-1 trial is to determine the efficacy of transfusion of COVID-19 convalescent plasma to adult patients admitted to hospital with COVID-19 infection at decreasing the frequency of in-hospital mortality in patients hospitalized for COVID-19. It is hypothesized that treating hospitalized COVID-19 patients with convalescent plasma early in their clinical course will reduce the risk of death, and that other outcomes will be improved including risk of intubation, and length of ICU and hospital stay. This pan-Canadian clinical trial has the potential to improve patient outcomes and reduce the burden on health care resources including reducing the need for ICU beds and ventilators.
The study is to evaluate the efficacy and safety of evobrutinib administered orally twice daily versus Teriflunomide (Aubagio®), administered orally once daily in participants with Relapsing Multiple Sclerosis (RMS). Participants who complete the double-blind treatment period (DBTP) and double-blind extension period (DBEP) prior to approval of a separate long-term follow-up study in their country will get an option for evobrutinib treatment continuation through a 96-week open-label extension (OLE) period.
The aim of the present study is to evaluate the effects of neuromuscular electrical stimulation (NMES) combined with conventional physiotherapy (Experimental Group), compared to conventional physiotherapy only (Control Group) in critically ill Intensive Care Unit (ICU) patients, by means of a randomized controlled clinical trial. The investigators expect that the NMES program will be able to reduce muscle structure and function losses compared to control group, and will improve muscle quality faster, will reduce the ventilation time and the total time spent at the ICU, as well as improve functionality of these patients. In addition, the researchers expect to understand which mechanisms determine such adaptations in the musculoskeletal system of these patients.
The Severe Acute Respiratory Syndrome COronaVirus 2 (SARS-CoV2) is a new and recognized infectious disease of the respiratory tract. Most cases are mild or asymptomatic. However, around 5% of all patients develop Acute Respiratory Distress Syndrome (ARDS), which is the leading mortality cause in these patients. Corticosteroids have been tested in deferent scenarios of ARDS, including viral pneumonia, and the early use of dexamethasone is safe and appears to reduce the duration of mechanical ventilation in ARDS patients. Nevertheless, no large, randomized, controlled trial was performed evaluating the role of corticosteroids in patients with ARDS due SARS-CoV2 virus. Therefore, the present study will evaluate the effectiveness of dexamethasone compared to control (no corticosteroids) in patients with moderate and severe ARDS due to SARS-CoV2 virus.
This is a phase 3, randomized, double-blind, placebo-controlled multicenter study to evaluate the efficacy and safety of colchicine in adult patients diagnosed with COVID-19 infection and have at least one high-risk criterion. Approximately 6000 subjects meeting all inclusion and no exclusion criteria will be randomized to receive either colchicine or placebo tablets for 30 days.
