Focusing Analytical Resources on Critical Parameters

A core tenet of modern quality management is the Risk-Based Approach Implementation, which dictates that resources should be allocated based on the potential impact on product quality. In the context of Process Analytical Technology, this means using risk assessment tools like Failure Mode and Effects Analysis (FMEA) to identify Critical Quality Attributes (CQAs) and their associated Critical Process Parameters (CPPs). PAT sensors and control strategies are then preferentially applied to monitor the most impactful steps, ensuring that the highest risks are continuously mitigated with the most rigorous control and analytical oversight.

Systematic Process Risk Prioritization

Systematic Process Risk Prioritization allows manufacturers to deploy PAT sensors strategically, maximizing the return on investment by focusing on the parameters most likely to affect the final product's efficacy and safety. This approach is highly favored by regulatory bodies, as it demonstrates a deep understanding of the manufacturing process and a proactive stance on quality control. This risk-based framework forms the basis for the regulatory strategy, allowing manufacturers to justify which parameters require continuous monitoring and which can be controlled through less intensive methods. Comprehensive technical guidance on applying this essential Process Risk Prioritization strategy is essential for all new product filings.

Continuous Process Verification by 2026

By 2026, the Risk-Based Approach Implementation will evolve into Continuous Process Verification (CPV). Instead of relying on periodic validation campaigns, the PAT system itself will continually collect and analyze data, proving that the process remains in a state of control year-round. This move from static validation to dynamic, real-time verification not only reduces compliance burden but provides unprecedented assurance of product consistency and quality throughout the entire product lifecycle.

Q: What is the main principle of the Risk-Based Approach Implementation in PAT? A: Allocating analytical resources (sensors, monitoring) preferentially to process parameters that have the highest potential impact on the product's quality attributes.

Q: What analytical tool is used to identify critical quality attributes (CQAs)? A: Risk assessment tools such as Failure Mode and Effects Analysis (FMEA) are used to systematically identify CQAs and the Critical Process Parameters (CPPs) that influence them.

Q: What is Continuous Process Verification (CPV)? A: A method where the PAT system continually collects and analyzes data to prove that the manufacturing process remains in a state of control throughout the product's entire lifecycle, replacing periodic validation campaigns.
