• File Naming Conventions: FDA mandates unique file names based on specific syntax, which must include the document type and content. This prevents naming conflicts during submission.
• Validation Reports: It is crucial to review the validation reports produced by the FDA’s eCTD validator. These reports indicate issues and need to be thoroughly addressed prior to resubmission.

To successfully navigate the FDA’s validation process, organizations should engage with eCTD validation services that specialize in pre-submission checks. This proactive approach minimizes the likelihood of technical rejections during the initial submission.

Step 3: eCTD Validation Services for the EMA

In the European Union, the EMA accepts eCTD submissions, but with some distinct validation criteria compared to the FDA. The EMA has published its own guidelines for eCTD validation, which can be accessed through the EMA’s official website.

Key elements of the EMA’s validation criteria include:

• Structured Metadata: Metadata must be arranged in a specific format to ensure proper referencing and linking within the eCTD submission. Misalignment can lead to validation failures.
• Document Accessibility: All documents need to be accessible for review. The EMA employs specific accessibility validators to ensure compliance.
• Submission Size:** eCTD submissions to the EMA must not exceed 10 GB, a limitation that may differ from other agencies and necessitate careful planning when assembling the submission files.
