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 purpose of this double-blind, randomized, controlled study is to evaluate the efficacy, immunogenicity, reactogenicity and safety of an adjuvanted recombinant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) trimeric spike (S)-protein subunit vaccine (SCB-2019) for the prevention of SARS-CoV-2-mediated COVID-19 in Participants Aged 12 Years and Older.
Radiotherapy has been confirmed as an important treatment breast-conserving surgery reducing the risk of any recurrence of breast cancer and breast cancer-related mortality in patients with early breast cancer. There are no comparative data on the ideal radiotherapy treatment regimen for patients with early stage breast cancer who underwent conservative surgery in the Brazilian population.
This is a longitudinal, one arm, prospective phase II study, designed to evaluate the efficacy of Olanzapine Netupitant and Palonosetron in the controll of nausea and vomiting induced by highly emetogenic chemotherapy.
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
Estimated number of participants: 342 participants with COVID-19 Design: Phase III, single-center, randomized, double-blind, parallel, placebo-controlled clinical study. In December 2021, there was a drop in the number of hospitalizations and the cases of COPD, tuberculosis and HIV associated with COVID-19, which are outside the inclusion criteria of this study. After the initial data of the study, there was a discussion with Anvisa and the size of the sample calculation was revised by amendment 4 (180 participants), and the methodology of statistical analysis for a new sample calculation was "a formula for sample calculation for superiority studies using proportions, according to the book do Chow et al (Chow, S.-C., Shao, J., Wang, H., &Lokhnygina, Y. Eds. 2017. Sample Size Calculations in Clinical Research: Third Edition, Chapman and Hall/CRC). Thus, Anvisa concluded that the adjustments are in accordance with the agency's guidelines, approving E4, which was later also approved by the Ethics Committee.
The primary objective of this study is to provide expanded access to and characterize the safety profile of Sotorasib in participants with previously treated locally advanced/unresectable/metastatic non small-cell lung cancer (NSCLC) with KRAS p.G12C mutation in a real-world setting.
The purpose of this study is to evaluate the efficacy and safety of Praga formulation in the treatment of neuropathic pain.
The current understanding of dental caries has not been completely transferred into the clinical practice to control caries lesion progression (severity / activity) and the individual risk of caries. This situation led to the development of the CariesCare International CCI Caries Management System (2018), derived from ICCMS™- International Caries Classification and Management System (2012) and the ICDAS - International Caries Detection and Assessment System (2002) in a consensus among more than 45 cariologists, epidemiologists, public health professionals, researchers and cliniciansfrom all over the world. The consensus aimed to guide dentists and dental teams in clinical practice, facilitating the control of the caries process and the maintenance of oral health in their patients. The general lack of implementation of an updated management of dental caries is evident in Colombia, in the survey of 1094 clinicians, teachers and students, failures were reported to adopt related behaviours, motivation barriers (remuneration), opportunity (in terms of relevance, physical/infrastructure resources, time) and training. As an additional barrier, the Colombian Chapter of the Alliance for a Cavity-Free Future (ACFF), evidences the absence of a facilitating Oral Health Record (OHR), this situation lead to stablish a new Alliance between the Ministry of Health and Social Protection (MSPS) and the AFLC to develop an inter-institutional consensus at the national level, of a clinical history for diagnosis and management of lesions and caries risk. Finally, 55 institutions participated in this consensus, and we have just finished a pilot test of the forms to submit a proposal for national standardization from the MSPS. The aim of this multicentre case series is to assess after 3, 6 and 12 months in children oral health outcomes, caregivers' satisfaction and in dentists' process outcomes, after the implementation of the CCI system adapted for the COVID-19 era -non-aerosol generating procedures. Oral health outcomes will be evaluated in terms of: - Effectiveness of CCI to control bacterial plaque, caries progression and caries risk, and to achieve behavioural change in oral health in children. - Acceptance of CCI caries management adapted for COVID-19 through Treatment Evaluation Interventory in dentists, and in children/parents through satisfaction questionnaire. - Costs of CCI adapted for caries management, in economic terms, number and appointment time.
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.
The Michelle trial is expected to provide high-quality evidence around the role of extended thromboprophylaxis in COVID-19 and will help guide medical decisions in clinical practice.
