A comprehensive understanding of the performance of an analytical procedure is a key element in the enhanced (Quality-by-Design) development approach described in the ICH Draft Guideline Q14 “Analytical Procedure Development”, but is also beneficial in more traditional approaches to method development and validation. Besides the identification and (as far as possible) elimination of systematic bias (thus ensuring accuracy), an appropriate knowledge of the random variability (common cause variation) is essential, as this error type contributes to all other performance characteristics.
Having established a reliable knowledge of the respective precision, statistical simulations can facilitate to evaluate the consequences to other performance attributes or investigations, such as calibration models, design of precision or transfer studies, reportable values etc. This approach allows to perform a large number of (simulated) “experimental” investigations, to gain a “feeling” on the interplay of precision, number of determinations, as well as acceptance criteria.
- Analytical laboratory managers and their colleagues charged with the day to day management and evaluation of laboratory data throughout the lifecycle, i.e. in method development, validation, transfer, specification setting, batch release and stability, continuous performance verification and change control.
- QA, manufacturing and regulatory affairs professionals
The participants will learn what statistical simulations are and how they can be applied to relevant questions in pharmaceutical analysis, such as
- Expected spread of data, standard deviations, means
- Interplay of standard deviation, number of determinations, and specification Limits
- Link between variability contributions of precision levels and expected mean difference (e.g. for transfer of analytical procedures)
The participants will receive an Excel file with simulation worksheets, which will be explained in the webinar and which can be used later for own applications.
