The European Commission (EC), the United States (US) Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have signed a new confidentiality commitment that allows the US regulator to share non-public and commercially confidential information, including trade secret information relating to medicine inspections with EU regulators. This confidentiality commitment is a milestone in the ongoing implementation of the mutual recognition of inspections of medicine manufacturers and it aims to strengthen the EU-US relationship. Ultimately it will contribute to a more efficient use of inspection resources by regulators for the protection of human and animal health.
