Established Conditions
ECs
What a definition is not
A definition is SPEQ’s plain-language decode of how a term is used in practice, cited to the documents that define it. It is a practitioner reference, not legal or regulatory advice, it does not replace the definition in the source, and where a regulator’s wording differs the regulator’s wording governs.
Established conditions are the legally binding elements of an approved application — descriptions of the product, manufacturing process, facilities, and controls — that assure product quality, and to which a change requires notification to the regulatory authority. Information in a dossier that is not an established condition can be updated under the firm's pharmaceutical quality system without a submission. Distinguishing the two is the core mechanic that ICH Q12 uses to make post-approval change management risk-based.
The practical exercise is to identify, for each part of the process and control strategy, which specific parameters and their reporting categories are binding — versus supportive detail that can evolve internally. A well-defined set of ECs reduces the volume of low-value regulatory submissions.
The approach to identifying ECs depends on how the process was developed (a parameter-based versus an enhanced/QbD approach can shift where the binding lines sit), so ECs connect back to the control strategy and CQAs/CPPs.
- —Legally binding dossier elements assuring quality; a change requires notification
- —Non-EC information can change under the PQS without a submission
- —Identification depends on the development approach and control strategy
- —The linchpin concept of ICH Q12 lifecycle management
