Prospective Validation
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.
Validation performed and completed before a new or modified process is released for routine commercial production or clinical use, with protocols approved and executed on a predetermined number of batches or runs prior to any distribution of product made under that process.
Prospective validation is the default, expected approach under current FDA and EU GMP guidance: no product from the validation runs reaches the market or the clinic until the full protocol has executed and its results have been reviewed and accepted. It corresponds to Stage 2 — Process Performance Qualification — within the modern three-stage process validation lifecycle.
It is distinguished from concurrent validation, where product from the qualification runs is released in real time under heightened controls, and from retrospective validation, which relies on historical production and testing data alone — an approach current guidance treats as acceptable only in narrow, exceptional circumstances, if at all.
