Findings

1Cleaning validation

Your firm failed to establish and follow adequate written procedures for cleaning and maintenance of equipment (21 CFR 211.67(b)). Your cleaning procedures lack sufficient detail to ensure repeatability between operators. We observed cleaning deficiencies and variability between operators, including wiping technique, using the same cleaning cloths for multiple areas, and failure to clean on top of the overhead light casings of the filling line. Further, the disinfection…

2Aseptic processing and sterility assurance

Your firm failed to perform operations within specifically defined areas of adequate size and to have separate or defined areas or such other control systems necessary to prevent contamination or mix-ups in aseptic processing areas (21 CFR 211.42(c)(10)). Equipment as a Route of Contamination The design of the aseptic processing line used to manufacture over-the-counter (b)(4) drug products was inadequate. Line (b)(4) is a traditional filling line consisting of an ISO 5 area…

For example: Lack of Written Procedures (211.100) Numerous written procedures were either missing or lacked sufficient detail to ensure consistent repeatability between operators. For example…

5Aseptic processing and sterility assurance

Your firm failed to establish and follow appropriate written procedures that are designed to prevent microbiological contamination of drug products purporting to be sterile, and that include validation of all aseptic and sterilization processes (21 CFR 211.113(b)). Inadequate Smoke Studies Smoke studies showed a lack of unidirectional airflow in your ISO 5 aseptic processing operation. Multiple instances of turbulent airflow in critical areas of filling line (b)(4) were…
