Drug Development Tools: Fit-for-Purpose Initiative


The Fit-for-Purpose (FFP) Initiative provides a pathway for regulatory acceptance of dynamic tools for use in drug development programs. Due to the evolving nature of these types of drug development tools (DDTs) and the inability to provide formal qualification, a designation of ‘fit-for-purpose’ (FFP) has been established. A DDT is deemed FFP based on the acceptance of the proposed tool following a thorough evaluation of the information provided. The FFP determination is made publicly available in an effort to facilitate greater utilization of these tools in drug development programs.
