In response to Executive Order (EO) 14293, FDA has developed a proposal, FDA PreCheck to accelerate the establishment of high priority new pharmaceutical manufacturing facilities in the U.S. and strengthen the domestic pharmaceutical supply chain. Specifically, the proposal consists of a two-phase approach: (1) Facility Readiness Phase, and (2) Application Submission Phase. In Phase 1, the Facility Readiness Phase, selected manufacturers can engage with FDA for early technical advice before a facility is operational through pre-operational reviews and utilization of a facility-specific Drug Master File to facilitate efficient evaluation of facility-specific elements prior to, and in support of, the submission of a drug application. In Phase 2, the Application Submission Phase, FDA and applicants build upon Phase 1 and engage through pre-submission meetings to resolve issues and expedite assessments of quality information in a drug application and inspections.
