Teams may interpret document freeze differently during submission preparation. Some understand that content cannot change, while others mean only that a particular compilation is preserved. Sponsors should state which package version is fixed for which purpose and leave a controlled route for necessary later changes.
Decision framework
Define package scope, cut-off time, document owners and open exceptions. Do not use a freeze as a substitute for scientific review or authorised approval. The compilation owner should identify accepted versions and pending inputs. Establish responsibility for impact assessment and recompilation before a change becomes necessary during final preparation.
Worked example
For example, a source product document changes after freeze while a local team has completed translation from the older file. The team does not silently insert the revision. It assesses affected documents and the need for further review. The frozen version and the new candidate package are distinguished so that a mixed compilation is not submitted accidentally.
Implementation checks
- Prepare a readable inventory of the frozen package showing document versions and the exceptions that remain open.
- Define who assesses new information and which authorised decision would reopen the package for further compilation work.
- Use appropriate checks to confirm that the version sent for submission matches the latest package accepted for that purpose.
Acceptance and boundaries
Accept handover when recipients can distinguish the applicable package from working drafts. This example defines no official filing rule or fixed deadline. Verify platform and country requirements separately; a freeze decision must not become a reason to avoid assessing necessary new safety information.
Frequently asked questions
- Can nothing change after a freeze?
- Necessary changes can follow suitable impact assessment and an authorised decision route.
- Is a folder name sufficient evidence?
- No. Content versions, intended purpose and acceptance status must also be clear.
