Animal Rule Information
Before a medical product can be approved by FDA, the sponsor must prove efficacy—that the product works. In some cases, such as developing medical countermeasures for potential bioterror threats, human challenge studies (exposing people to the threat agent) would not be ethical or feasible.
In these cases, FDA may grant approval based on well-controlled animal studies, when the results of those studies establish that the drug or biologic product is reasonably likely to produce clinical benefit in humans. The product sponsor must still demonstrate the product’s safety in humans.
