S. 705: Innovation in Pediatric Drugs Act of 2025

This bill expands the Food and Drug Administration’s (FDA’s) authority with respect to research on rare pediatric diseases, including by permitting the FDA to require pediatric studies on certain orphan drugs and to take enforcement action against drug sponsors that fail to satisfy pediatric study requirements.

Specifically, the bill would impose pediatric study requirements on drugs for rare diseases or conditions (i.e., orphan drugs) if the FDA determines that (1) the drug could improve the treatment, diagnosis, or prevention of a disease compared with currently available products for the relevant pediatric population; or (2) there is a need for additional options within the drug’s class or indication. (Under current law, pediatric study requirements generally do not apply to orphan drugs.) The FDA must issue guidance describing how these changes will be implemented, including information on how waivers will be granted.

The bill also permits the FDA to take enforcement action against drug sponsors that fail to comply with pediatric study requirements, if such sponsors demonstrated a lack of due diligence in satisfying the requirements.
