The aim of this two day course is to provide guidance to apply the principles of the modern concept of lifecycle management to analytical methods, as initiated by the PhRMA/EFPIA Position Paper [QbD Analytics. Implications and Opportunities of Applying QbD Principles to Analytical Measurements, Pharmaceutical Technology, Feb. 2010, 2-8] and further elaborated by USP’s Validation and Verification Expert Panel in a Stimuli Article for a proposed USP General Information Chapter [1220 The Analytical Procedure Lifecycle. Pharm. Forum 43(1)]. The application of Quality-by-Design principles during the whole analytical lifecycle provides opportunities, not only for new development products, but also for drugs already marketed. This course will deal among others with the following questions:
- What is the content of the three stages of analytical lifecycle aligned current process validation concepts?
- What are the opportunities of applying QbD principles to analytical lifecycle management?
- How can the Analytical Target Profile (ATP) help to define the measurement requirements and increase regulatory flexibility?
- Why is it important to have a clear understanding and expectation of method performance?
- What is the benefit of a risk-based method development and establishment of an appropriate Method Control Strategy?
- What is the impact and benefit of an integrated lifecycle approach on method verification, transfer, and changes?
- Why is a continued method performance monitoring important, and how can it be achieved?
Six interactive workshops will be provided throughout the two days which will enable delegates to understand and discuss the concepts in more detail, and to be able to apply what they have learned. Delegates will have the opportunity to work through the whole analytical lifecycle by gaining “hands-on experience” using several case studies.
During the course an overview of the PhRMA/EFPIA Position Paper and the Stimuli Article for a proposed USP General Information Chapter <1210> will be provided which are based on the Analytical Target Profile (ATP) concept. The ATP defines the objective of the test and quality requirements for the reportable value. It therefore aligns with the ICH definition of QbD as “a systematic approach that begins with predefined objectives and emphasizes product and process understanding and process control, based on sound science and quality risk management” [ICH Q8]. Besides serving as focal point throughout the analytical lifecycle, the ATP has the potential to facilitate continuous improvement if regulatory authorities would approve the requirement-based ATP instead of specific methods. Each method conforming to the ATP requirements could be implemented by the company’s internal change control management system, thus providing regulatory flexibility.
The three stages of the analytical lifecycle align with current process validation concepts. In Stage 1, the ATP is used to drive method design and development activities. Risk assessment tools and statistical methods used to facilitate understanding of the method (e.g. robustness, design of experiments) and its performance characteristics (e.g. accuracy and precision) and their acceptance criteria will be discussed in the course.
Stage 2, Method Performance Qualification, confirms that the analytical procedure, operated in the routine
environment is capable of delivering reproducible data which consistently meet the ATP. This includes the finalisation of the Method Control Strategy, e.g. a science-based definition of the replication level of the reportable value. This stage includes also holistically analytical transfer and implementation of compendial procedures.
An important aspect in the lifecycle approach is Stage 3, the Continued Method Performance Verification, i.e. the ongoing assurance that the analytical procedure remains continuously in a state of control. This includes an ongoing program for routine monitoring of analytical performance data, as discussed in the FDA Method Validation Guideline from July 2015, and the systematic evaluation of changes.
Note: In order to fully benefit from the workshops, attendees should preferably bring a notebook with Excel®.
This course is designed for analytical managers and scientists who are responsible for performing or reviewing activities like method development, validation, transfer, operation of methods in a QC environment, statistical evaluation of method performance, analytical change control etc.
In addition, QA and regulatory affairs professionals will benefit from this course by gaining an understanding in future CMC trends. This will aid more effective multifunctional discussions on these topics within industry.
