Inspection Cites Thermo Fisher Manufacturing Facility
FDA has cited significant manufacturing and quality control deficiencies at a facility operated by Thermo Fisher Scientific (Patheon Italia unit) in Ferentino, Italy, following a 2/2025 inspection. The inspection identified lapses in quality unit oversight, including failures to properly document and investigate deviations, inadequate control over testing and inspection processes, and insufficient verification of sample handling and microbial testing timelines, according to a just-posted FDA Form 483.
Regulators also flagged concerns with process controls, noting the company did not adequately validate certain manufacturing steps or ensure consistent performance of critical equipment. In one instance, repeated production stoppages were not fully investigated, raising questions about process reliability and product consistency.
FDA further cited shortcomings in sterility assurance practices, including gaps in aseptic process simulations and operator training. Inspectors observed instances where sterile components may have been compromised during handling, and noted delays in implementing corrective actions for previously identified risks.
Additional observations pointed to weaknesses in visual inspection programs for injectable drug products, with inadequate training, poorly designed qualification procedures, and insufficient assurance that products are free from particulate contamination. The agency also raised concerns about environmental monitoring and cleaning practices in classified manufacturing areas, including limited sampling, insufficient validation of disinfectants, and failure to simulate worst-case conditions during qualification studies.
