Which Firms Will the FDA Inspect More Frequently in the Future?
Can you identify alternative approaches that would systematically prioritize manufacturing sites for GMP inspections?
One member suggested distinguishing between different risks associated with the products and processing lines, although the Subcommittee recognized the importance of an effective quality system associated with pharmaceutical production.
One member suggested the use of a decision tree in order to prioritize sites according to the expected utilities.
In addition, the Subcommittee recommended that FDA consider the distribution of sites selected by the model to consider whether there is a representative balance between generic and innovator sites and between biotech and conventional manufacturing sites.
In what areas would additional data provide the most value added in prioritizing manufacturing sites for GMP inspections?
One member expressed concern that high volume of production should not be given too much weight as a criterion to prioritize sites for inspection and suggested a "volume-risk index" that would fully take into account factors that mitigate risks, some of which may be associated with high volume production.
The Subcommittee emphasized that historical inconsistency among investigator findings might limit the utility of such findings in prioritizing sites for inspection, but the Subcommittee recognized that this limitation should become less problematic over time as the new Pharmaceutical Inspectorate program is implemented.
The Subcommittee agreed that it would be crucial to ensure that the model promotes the correct incentives that encourage robust quality systems, continued availability of medically important drugs, and continuous improvement.
Are there other metrics that should be incorporated, e.g., measuring process control?
The members felt that companies with a high turnover of personnel might be a helpful indicator to include but that it may be difficult to obtain good data on this factor. One member stated that expert testimonies are a positive step in the agency's risk-based analyses, but wanted to ensure that such testimonies would be formally incorporated into the analyses.
The members highlighted that understanding of high-risk areas is a helpful tool for both FDA and industry in allocating resources. The members emphasized that FDA needs to help industry understand the model ranking factors with appropriate transparency, to allow firms to improve their ranking by moving toward the desired state, and to allow them to appropriately allocate their internal resources.
