This article provides a concise overview of the clinical research landscape concerning Rare Diseases in Brazil. Rare Diseases, affecting a small portion of the population, present a substantial public health concern. Estimates suggest that between 7 to 12 million Brazilians may be affected by these conditions. Despite incomplete epidemiological data on Rare Diseases in Brazil, collaborative efforts among various institutions are underway to address this gap. The Brazilian Policy of Comprehensive Care for People with Rare Diseases was launched in 2014 aiming to enhance diagnosis and follow-up care, thereby facilitating recruitment for clinical trials. The approval process for clinical studies in Brazil involves rigorous ethical evaluation by CEPs-Comitês de Ética em Pesquisa (Research Ethics Committees) and CONEP-Comissão Nacional de Ética em Pesquisa (National Commission on Ethics in Research), along with regulatory assessment by Anvisa-Agência Nacional de Vigilância Sanitária (the Brazilian Health Regulatory Agency). While timelines for approval can be lengthy, recent regulatory changes are streamlining the process. Despite challenges, conducting clinical research on Rare Diseases in Brazil offers unique opportunities for large, inclusive and diverse patient populations. The evolving regulatory landscape and collaborative initiatives hold promise for accelerating clinical trial participation and advancing therapeutic options for Rare Diseases, consequently improving patient outcomes and quality of life.
