The US Food and Drug Administration recently announced that, for the development of certain drugs, it will be phasing out animal testing in favor of more effective, human-centered methods — like AI-based models, organoids and organ-on-a-chip systems.

Artificial intelligence can predict a drug’s behavior in the human body. Organoids are clusters of lab-grown human cells that mimic individual organs, which can be used to assess a drug’s safety. Organs-on-a-chip are thumb drive sized translucent chips that contain tiny channels lined with organ-specific human cells. They’re designed to recreate the physiology of the organ, such as the flow of blood or air, making them exquisite models for diseases and drugs.

Not only will these systems be human-specific — they’ll save countless animals’ lives.
