The Transforming the Regulatory Environment to Accelerate Access to Treatments (TREAT) proposed by Senator Kay Hagen (D,NC) would create two new FDA approval pathways. Drugs would be eligible for "progressive" or "exceptional" approval if they provide meaningful advances in the treatment of an unmet serious or life threatening condition. FDA could also approve drugs based on approval in the EU as well as in Australia, Canada and some other countries.
TREAT would permit progressive approval based on data "reasonably likely" to predict clinical benefit, the standard currently used for accelerated approval. Unlike accelerated approval, drugs could receive progressive approval without data from a surrogate endpoint. Exceptional approval could be granted when the data necessary to satisfy the standard for approval "cannot ethically, feasibly or practicably be generated." would also relax conflict of interest restrictions for advisory committee members, create a fixed term for the FDA commissioner, and revise FDA's mission statement to emphasize the promotion of biomedical innovation.
