3D-printed chip showing body’s reaction to drugs could end need for animal tests

She added: “This device shows really strong potential to reduce the large number of animals that are used worldwide for testing drugs and other compounds, particularly in the early stages, where only 2% of compounds progress through the discovery pipeline.”

Tavares said there were other benefits beyond simply eliminating the need for using animals in early drug development.

“This non-animal approach could significantly reduce cost of drug discovery, accelerate translation of drugs into the clinic, and improve our understanding of systemic effects of human diseases, by using models that are more representative to human biology than animal models.”
