Updates on ISO 14155 and N=1 Therapeutics Discussed by TGA
Investigators need to modify trial protocols and safety reporting mechanisms in line with the latest ISO 14155 updates to ensure compliance for upcoming high-risk clinical trials.
Primary source: Food and Drug Administration (FDA)
Introduction of stricter technical validation rules for electronic submissions; reports lacking fields B5 (event description) and H1 (reportable event type) in Form 3500A will be rejected starting July 20, 2026. ISO 3166-1 alpha-2 country codes will no longer be accepted.
This change ensures accurate and compliant reporting in line with international standards, impacting all users of the eMDR system and potentially affecting the usability of electronic safety reporting systems.
Update electronic safety reporting systems and pharmacovigilance databases to implement new rules to ensure all submissions use GENC 3-letter country codes and include the required fields as of July 20, 2026.
Regulatory Intelligence Lead
Review before 2026-06-29.
Scheduled maintenance outage from July 22 to July 27, 2026; mandatory transition to GENC 3-letter country codes for electronic submissions; implementation of IMDRF 2025 maintenance updates for Adverse Event problem codes in sections F10 and H6 of Form 3500A; minor changes to Ack3 error messages due to AEMS consolidation.
Manufacturers and importers of medical devices must update their electronic reporting systems and internal coding libraries to support GENC 3-letter country codes and updated IMDRF AE codes. PV operations should account for the July 22-27 outage window by including a specific statement in Block H11 for impacted reports and preparing for delays in receiving electronic submission acknowledgments. System updates for AS2/API users must be completed by March 31, 2027.
Delay in acknowledgment messages Ack3 and Ack4 during outage; submitters should avoid submissions.
Outage period for electronic submissions
Submitters must transition to GENC 3-letter country codes for accurate submissions.
No longer accepting specific country codes
Update electronic safety reporting systems and pharmacovigilance databases to implement new rules to ensure all submissions use GENC 3-letter country codes and include the required fields as of July 20, 2026.
The FDA’s eMDR system will undergo significant enhancements including the rejection of reports missing critical fields and the transition from ISO 3166-1 alpha-2 country codes to GENC alpha-3 codes. Compliance updates are required by July 20, 2026, to avoid report rejections.
What changed: Introduction of stricter technical validation rules for electronic submissions; reports lacking fields B5 (event description) and H1 (reportable event type) in Form 3500A will be rejected starting July 20, 2026. ISO 3166-1 alpha-2 country codes will no longer be accepted.
Why it matters: This change ensures accurate and compliant reporting in line with international standards, impacting all users of the eMDR system and potentially affecting the usability of electronic safety reporting systems.
Practical implication: Update electronic safety reporting systems and pharmacovigilance databases to implement new rules to ensure all submissions use GENC 3-letter country codes and include the required fields as of July 20, 2026.

Investigators need to modify trial protocols and safety reporting mechanisms in line with the latest ISO 14155 updates to ensure compliance for upcoming high-risk clinical trials.
Safety lead to: (1) perform a UK-clinical-trial safety reporting gap assessment against MHRA’s effective guidance sections (MedDRA coding; AE/SAE; RSI governance; SUSARs; annual safety reporting; USMs; serious breaches; temporary suspension), (2) update controlled SOPs/WIs and training records to reflect “effective” status as of 28 Apr 2026, and (3) document deviations/gaps and open CAPA where needed for ongoing UK trials and new submissions.
Sponsors and MAHs must review and align safety data collection and reporting protocols with the newly adopted guidelines while preparing for implementation of PRAC recommendations stemming from this meeting.
Healthcare facilities must utilize the new checklist during inspections to conduct gap analyses and ensure compliance with reporting requirements associated with their vigilance systems.
