What is ESG NextGen?
The Food and Drug Administration (FDA) Electronic Submissions Gateway Next Generation (ESG NextGen) is the FDA’s modernized platform for securely receiving and processing electronic regulatory submissions with improved architecture that supports greatly expanding submission bandwidth and storage. ESG NextGen provides a high-performance gateway for FDA and its global partners, allowing the seamless submission of regulatory documents and enabling the FDA to streamline review processes. ESG NextGen functions as a unified solution, serving as a single-entry point for the secure submission, receipt, acknowledgment, routing, and notification of all regulatory submissions to the FDA.
- Unified Submission Portal (USP): The ESG NextGen USP is a user-friendly web-based platform which replaces the legacy WebTrader user interface. The USP provides the ability to submit regulatory information to the FDA and track the status through Center receipt.
- API Integration: ESG NextGen’s suite of APIs enables programmatic submissions, allowing organizations to integrate submission processes directly into their internal systems. This option supports the automation of submission workflows and real-time status tracking through Center receipt of the submission.
- Applicability Statement 2 (AS2): A system-to-system connection for an automated data exchange between the FDA and its partners.
Where Do Submissions Go?
ESG NextGen acts as a secure conduit for all electronic submissions to the FDA. Each submission is automatically routed to the appropriate FDA Center or Office based on user selections chosen during the submission process. ESG NextGen itself does not open or review submissions but serves as a secure and efficient channel for ensuring regulatory information reaches its destination.
