RESUMO
The SARS-CoV-2 outbreak focused global attention on the shortcomings of the drug discovery process. It led to its acceleration in several areas, particularly in the processes associated with the development and approval of COVID-19 vaccines. This situation contrasts with the low approval rates of new drugs for respiratory system diseases (e.g. asthma, chronic obstructive pulmonary disease, cancer, tuberculosis), which are leading causes of morbidity and mortality worldwide. In this context, innovation in respiratory system drug discovery is surely needed, and it is most likely to succeed through the use of preclinical models that are cost-effective, high-throughput and generate predictive human-relevant outcomes. Here, we highlight several non-animal new approach methodologies (NAMs) and their applications in respiratory research. We describe their potential uses for efficacy and toxicity assessments, to optimise the drug development process and reduce the high failure rates in clinical trials.

The use of animals in research and education is a controversial topic that has raised extensive debates. Undergraduate students (n = 404) and lecturers (n = 62) from biomedical science schools at the Federal University of Goiás (UFG) in the municipality of Goiânia, Jataí and Catalão, Goiás, Brazil, were asked about their knowledge and opinions on bioethics, the use and importance of animals in education, the replacement of animal use with non-animal alternatives, and the current legislation of the National Council for the Control of Animal Experimentation (CONCEA) that bans animal use in some practical classes within technical and higher education (i.e. Resolution No. 53/2021). Most students and lecturers agreed not only that animal use can contribute to education, but also that it is important to replace this animal use with innovative non-animal alternatives where appropriate. The lecturers emphasised that the replacement of animal models will be possible only with the provision of appropriate training to improve the skills of educators in their use, as well as ensuring reliable access to suitable facilities and materials.
