Implementation of new guidelines for variations to the terms of Marketing Authorisations

On the 2nd of December, INFARMED I. P. issued an Informative Note 136/CD/100.20.200 notifying a transitional period leading up to 15th January, 2026, after which the new Guidelines for Variations to the terms of Marketing Authorisations (MA) (C/2025/5045) will take place. From 15th January, variations submitted according to the categories defined in the current guidelines in force since 2013 will not be accepted.

For Type IA variations:

• All variations implemented in 2025 must be included in an annual update in December 2025 or by the 14th January, 2026.

• The type IA variations not included on the annual update could be submitted on an anticipated annual update or by submission of a single IA variation.

• Variations foreseen as exceptions to the annual updates may be submitted as individual notifications.

• A new annual update cycle will start from the first implemented type IA variation after the 15th January 2026, excluding the exceptions to the annual updates.

Concerning the SMUH-Alter platform, every variation submitted until 14th January 2026  with a payment issued will be assessed according to the current guidelines, however, all submissions after this date, the SMUH-Alter will only have available the variations covered by the new guidelines.

As the industry moves toward the new legal framework reflecting the 2024 amendment of the Variations Regulation, proactive adaptation is essential for all ongoing and future variation submissions.
