O.S.A is a non-profit Italian Association that recognizes the human relevance and translational limitations of the current paradigm in biomedical research and drug discovery, and the need for change.  We bring together scientists, researchers, graduated in medicine, veterinary, biology, psychology, pharmacology, etc. and volunteers to promote human-based and human-relevant alternatives to animal use in research, testing, and education.

We aim to provide members of the public, patients, policy makers, journalists, teachers and students, scientifically accurate, evidence-based information about human-based / human-relevant research and why it's a scientific necessity for the advancement of human medicine to move away from conventional research paradigm, and start implementing modern technologies.
