1. Charles River Laboratories International, Inc. (NYSE:CRL)

Charles River’s share prices fell by 28.13 percent on Thursday to end at $99.95 apiece as investors sold off on news that the Food and Drug Administration (FDA) officially phased out animal testing requirements to switch to Artificial Intelligence methods.

The move was a low blow to the company, having specialized in traditional animal trials.

According to the FDA, the initiative was designed to replace animal testing with more effective human-relevant methods in the development of monoclonal antibody therapies and other drugs.

The move was not only expected to improve drug safety and expedite the evaluation process, but it could also result in lower research and development costs, thereby reducing drug prices for the end consumers.

According to the FDA, it will begin to encourage the inclusion of New Approach Methodologies (NAMs) data in investigational new drug applications.
