The Research Ethics Committee (CEP) has become an essential mechanism for social control in Brazilian research involving human subjects, contributing to the development of studies guided by ethical standards and to the protection of research participants. This article analyzes the performance of CEP in Western Amazonian institution, its history, operating conditions, trends, and different aspects between 2018 to 2022. The theoretical framework addresses the history of research involving human subjects, the origins and evolution of bioethics in the international context, bioethics in Brazil, and regulations on the ethical analysis of research. The data were collected through the Brazil Platform and reports from the institution's CEP. The CEP evaluated 865 research protocols, most of which were from Health Sciences. Additionally, it was observed that during 2018 to 2022 the covid-19 pandemic had a negative impact on the number of projects submitted for evaluation to the CEP. The 57% drop in the number of projects registered during 2020/2022 reveals the negative impact of this event on the execution of projects with human participants.
