Questions & Answers: Positions on specific questions addressed to the EWP therapeutic subgroup on Pharmacokinetics

Background
In the context of assessment procedures, the Therapeutic Subgroup on Pharmacokinetics of the Efficacy Working Party (EWP-PK subgroup) is occasionally consulted by the CHMP or, following CHMP’s agreement, by other Committees, Working parties or the CMD(h). The objective is to address specific questions in relation to pharmacokinetic evaluations and particularly the requirements and assessment of bioequivalence studies. The positions, which are being elaborated by the EWP-PK subgroup in response to such questions, are being forwarded to the enquiring party for consideration in their assessment.

It is understood that such position will be reflected in the procedure-related assessment reports if applicable. In some cases however, these position might also be of more general interest as they interpret a very specific aspect that would not necessarily be covered by guidelines. This paper summarises these positions which have been identified as being within this scope.

It should be noted that these positions are based on the current scientific knowledge as well as regulatory precedents. They should be read in conjunction with the applicable guidelines on bioequivalence in their current version. As the questions have initially been raised in the context of specific assessment procedures, details of these procedures have been redacted for reasons of confidentiality.

This compilation will be updated with new positions as soon as they become available. Likewise, if a position is being considered outdated, e.g. due to new evolutions in the scientific knowledge including revisions to the applicable guidelines, positions will be removed from this document.

The positions in this document are addressing very specific aspects. They should not be quoted as product-specific advice on a particular matter as this may require reflection of specific data available for this product. By no means should these positions be understood as being legally enforceable.
