The pandemic has forced a rethink of clinical research, but the pharma industry continues to rely on animal testing. While pundits have observed that computer modeling and techniques such as microdosing can reduce animal testing, animal testing continues to be integral in preclinical studies.
But computer models are now sufficiently accurate to predict the response of many drugs, said David Harel, CEO of CytoReason (Tel Aviv, Israel). “We are getting to the point that computer models of certain diseases can generate better predictions than animal models,” he said.
But there are caveats. It could take longer to move from animal-based safety testing, which often involve rodents. Such animal trials tend to be limited in size. “They’re not a big burden. And they’re not super expensive,” Harel said. And regulators frequently consider animal data when evaluating drug safety. But …
