EMA Checklist: Updated Validation checklist for Type II quality variations
Recently on 10th February 2023, the European Medicines Agency (EMA) updated and released their "Validation checklist for Type II quality variations".

The EMA defines variation as a change to the terms of a marketing authorisation. A variation regulation governs the procedures for amending the marketing authorisation and technical dossier following the decision.
The following categories of variations are defined in Article 2 of the Variations Regulation:
Minor variations of Type IA
Minor variations of Type IB
Major variations of Type II
Extensions
Urgent safety restriction
According to Commission Regulation (EC) No 1234/2008 (the Variations Regulation), a major variation of type II is a variation that does not extend the marketing authorisation (line extension) but may significantly affect the safety, quality, or efficacy of a medicinal product.
