Although QRM is not new (cf. CHQ9 - 2005), the regulatory focus on QRM will increase with the arrival of the European Medicines Agency’s Annex 1, which was reviewed by the US Food and Drug Administration, the World Health Organization, and the Pharmaceutical Inspection Convention Scheme. Integrity testing of sterilizing-grade filters is a key focus of QRM because it is a fundamental element of sterility assurance.The following presentation points out the insufficiency of traditional QRM for filter-integrity testing and advocates for a comprehensive approach. Such a method offers thorough identification of possible failure modes, ways to prevent failures, and improved detectability through use of program-specific parameters for automatic detection of abnormal conditions, thus avoiding false passed and false failed test results.
