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 study is a randomized, double-blind, multicenter, placebo-controlled trial to evaluate the safety and efficacy of a novel therapeutic agent, Novaferon, in hospitalized adult patients diagnosed with COVID-19. The study is comprised of two cohorts: - Cohort A: This is a blinded safety lead-in comprising two arms. 40 patients will be randomized on a 1:1 basis to receive either Novaferon or matched placebo via a commercial nebulizer, plus Standard of Care (SOC) - Cohort B: This is the main portion of the study, which comprises two arms. Up to 874 patients will be randomized on a 1:1 basis to receive either Novaferon or matched placebo via a commercial nebulizer, plus SOC
The purpose of this study is to evaluate the efficacy and safety of Praga formulation in the treatment of neuropathic pain.
Acute gastrointestinal bleeding is potentially lethal in liver cirrhosis. Accurate assessment of prognosis is critical in a timely fashion. A novel model, CAGIB score, has been developed based on our Chinese multicenter retrospective study. Now, a prospective, international multicenter, observational study will be performed to further compare the performance of CAGIB versus Child-Pugh and MELD scores for evaluating the in-hospital mortality of patients with liver cirrhosis and acute gastrointestinal bleeding.
This is a global Phase III, randomized, placebo-controlled, double-blind study designed to evaluate the efficacy and safety of adjuvant treatment with atezolizumab compared with placebo in participants with MIBC who are ctDNA positive and are at high risk for recurrence following cystectomy.
The purpose of study is to compare bladder intact-event free survival (BI-EFS) in participants receiving TAR-200 in combination with intravenous (IV) cetrelimab versus concurrent chemoradiotherapy.
This is a multi-center multi-national rollover study to allow continued access to crizanlizumab for patients with sickle cell disease (SCD) who are on crizanlizumab treatment in a Novartis-sponsored study (parent study) and are benefiting from the treatment as judged by the investigator.
Study WR42221 is a Phase IIIb, global, multicenter, randomized, visual assessor-masked study designed to assess the efficacy, safety, and pharmacokinetics of the Port Delivery System with ranibizumab (PDS) 100 mg/mL delivered every 36 weeks (Q36W) compared with every 24 weeks (Q24W) in patients with neovascular age-related macular degeneration (nAMD).
This study evaluates TL-895, a potent, orally-available and highly selective irreversible tyrosine kinase inhibitor for the treatment of Myelofibrosis (Cohorts 1-3) or Indolent Systemic Mastocytosis (Cohort 5). Participants must be diagnosed with Myelofibrosis and be relapsed/refractory (e.g., having failed prior therapy), intolerant, or ineligible to receive JAKi treatment, or be diagnosed with Indolent Systemic Mastocytosis.
This is a case series of patients with COVID-19 admitted to the northeast Brazil region, in a referenced hospital for COVID-19, during the 2020 COVID-19 pandemic. Data will be collected prospectively and retrospectively. The main objective is to describe the characteristics of critically ill patients with COVID-19 and their clinical outcomes, and to identify risk factors associated with survival, to guide the strategy to mitigate the epidemic, both within each hospital and ICU and in public health management.
The present study aims to describe the results of a modified gastric bypass surgery to ensure endoscopic access to the excluded remaining stomach, as well as to monitor the clinical conditions of comorbidities and the patient's quality of life, since associated complications can be found to the excluded stomach, such as: bile reflux, gastritis and / or gastric and duodenal ulcer, H. pylori infection, bleeding, gastric polyps and the possibility of gastric cancer in patients undergoing RYGB (Roux-en-Y gastric bypass), with one of the probable factors being the occurrence reflux of the duodenal content into the excluded portion of the stomach. In this sense, based on technical concepts of an established surgical procedure, the RYGB, the present project is not a proposal for a new procedure, but an adaptation of an existing technique. The proposal of the present study is about adaptations in RYGB surgery, which will enable endoscopic access to the remaining stomach, through the creation of a gastric communication.
