Established Conditions in Analytical Procedure: Overview, Regulatory Examples and an FDA Laboratory Study



17th September 2024 | 10:00am EDT / 7:00am PDT / 3:00pm BST / 4:00pm CEST | Jinhui Zhang, Chemist at FDA/CDER and Dimple Shah, Pr. Scientist at Waters Corporation |BOOK FREE SEAT FOR THIS WEBINAR

Established conditions (ECs) are manufacturing and control elements considered necessary to assure product quality (e.g., ECs in manufacturing process) and to help assure method performance (e.g., ECs in analytical procedures). ECs in analytical procedures help to maintain reliable results that can ensure the efficient product control strategy during the product life cycle. Changing ECs in analytical procedures may necessitate a certain level of regulatory activity and the level of regulatory activity can be different depending on the strategy defining ECs and the extent of changes. The presentation will first provide a high-level overview of harmonized scientific risk-based approaches for identifying ECs and determining the corresponding reporting categories based on scientific principles described in ICH Q12 and Q14 guidelines. Then, two regulatory examples involving ECs in analytical procedures will be discussed. It is noteworthy mentioning that both parameter and performance-based ECs in an analytical procedure are defined in these two examples. The last part of the presentation will be an FDA laboratory study on a mass spectrometry method for a recently identified NDSRI (Nitrosamine drug substance-related impurity). In this case study, analytical variables and method robustness were investigated according to recommendations from the ICH Q2R2 (draft) Guideline. Based on the impact of each variable on method performance, categorical and numerical ECs were proposed.
