AI-Driven Drug Discovery Accelerates as FDA Pushes to Reduce Animal Testing

AI Revolutionizes Drug Discovery and Testing

In a significant shift for the pharmaceutical industry, drug developers are increasingly turning to artificial intelligence (AI) technologies for discovery and safety testing. This move aligns with the U.S. Food and Drug Administration's (FDA) push to reduce animal testing in the near future, potentially transforming the landscape of drug development 1

Dramatic Reduction in Time and Costs

According to experts from contract research firms, biotech companies, and brokerages, the adoption of AI and reduction in animal testing could slash drug development timelines and costs by at least half within the next three to five years 1

. This aligns with the development of "new approach methodologies" (NAMs), which include:

• AI and machine learning
• Computer-based modeling
• Human-based models like organs-on-chips

Charles River, a major research contractor, has already generated about $200 million in annual revenue from its NAM portfolio 1
