Abstract
Clinical trials must be approved and monitored by ethical and regulatory authorities to ensure that the ethical conduct and technical aspects of the research are in compliance with required standards. The in-depth understanding of this process is crucial for studies to be delineated and conducted in accordance with applicable standards, being an essential part of national technical and scientific training. The evaluation of the studies in Brazil is performed by the research ethics committees, by the National Research Ethics Commission and by the Brazilian regulatory agency, the Agência Nacional de Vigilância Sanitária (National Health Surveillance Agency). Researchers and sponsors claim that the time taken for approval and initiation of clinical trials limits further studies. However, Brazilian standards are constantly improving, demonstrating the interest and ability to improve procedures, without losing quality in ethical evaluation.
