RESUMEN
The analytical procedure life cycle (APLC) provides a holistic framework to ensure analytical procedure fitness for purpose. USP's general chapter <1220> considers the validation activities that take place across the entire analytical procedure lifecycle and provides a three-stage framework for its implementation. Performing ongoing analytical procedure performance verification (OPPV) (stage 3) ensures that the procedure remains in a state of control across its lifecycle of use post validation (qualification) and involves an ongoing program to collect and analyze data that relate to the performance of the procedure. Knowledge generated during stages 1 (procedure design) and 2 (procedure performance qualification) is used as the basis for the design of the routine monitoring plan to support performance verification (stage 3). The extent of the routine monitoring required should be defined based on risk assessment, considering the complexity of the procedure, its intended purpose, and knowledge about process/procedure variability. The analytical target profile (ATP) can be used to provide or guide the establishment of acceptance criteria used to verify the procedure performance during routine use (e.g., through a system/sample suitability test (SST) or verification criteria applicable to procedure changes or transfers). An ATP however is not essentially required to perform OPPV, and a procedure performance monitoring program can be implemented even if the full APLC framework has not been applied. In these situations, verification criteria can be derived from existing validation or system suitability criteria. Elements of the life cycle approach can also be applied retrospectively if deemed useful.
RESUMEN
Recent changes in the pharmaceutical industry have led to significant paradigm shifts in the pharmaceutical quality environment. Globalization of the pharmaceutical industry, increasingly rapid development of novel therapies, and adoption of new manufacturing techniques have presented numerous challenges for the established regulatory framework and quality environment and are impacting the approaches utilized to ensure the quality of pharmaceutical products. Regulators, industry, and standards-setting organizations have begun to recognize the need to rely more on integrated risk-based approaches and to create more nimble and flexible standards to complement these efforts. They also increasingly have recognized that quality needs to be built into systems and processes throughout the lifecycle of the product. Moreover, the recent COVID-19 crisis has emphasized the need to adopt practices that better promote global supply chain resilience. In this paper, the USP Quality Advisory Group explores the various paradigm shifts currently impacting pharmaceutical quality and the approaches that are being taken to adapt to this new environment. Broad adoption of the Analytical Procedure Lifecycle approach, improved data management, and utilization of digital technologies are identified as potential solutions that can help meet the challenges of these quality paradigm shifts. Further discussion and collaboration among stakeholders are needed to pursue these and other solutions that can ensure a continued focus on quality while facilitating pharmaceutical innovation and development.
