The use of the updated EU Module 1 Specification v3.0 and/or v3.0.1 is now mandatory for all eCTD format submissions in the EU. The use of the XML delivery files for submissions via the eSubmission Gateway and the Web Client is now mandatory. The use of XML delivery files has replaced the use of filenaming conventions for majority of human and veterinary submissions to the EMA. The Annexes describing the filenaming conventions have been updated. Applicants are reminded that the section 2 of the electronic Application Form (eAF) should be filled in. The use of the footnote is only allowed for form and strength information for complex vaccines/combination products.
