In medical research, ethical committees are responsible for ensuring that experimentation and methodological studies on human subjects are carried out in accordance with national and international well-established guidelines. In general, experimentation on human subjects is framed in a line of phased clinical trials. The ethics committees are organizations composed of medical specialists, scientific researchers, non-medical and non-scientific members who work together to ensure the protection of the rights, health and safety of the human subjects involved in such clinical trials.
