FDA Cites Sterile Compounding Lapses at Nubratori
FDA has cited Nubratori Inc., a California-based sterile drug outsourcing facility, for multiple manufacturing and contamination-control deficiencies following a December inspection of the company’s Torrance site, according to an agency inspection report. The Form FDA 483 said the company failed to establish adequate written procedures for cleaning and maintaining manufacturing equipment. Inspectors also faulted the company for selecting a non-sterile product as its designated “worst-case” compound without sufficient scientific justification and for continuing to rely on that designation even after introducing new sterile injectable products with potentially greater cross-contamination risks. In addition, FDA said Nubratori performed a cleaning verification activity in 2025 without first completing adequate cleaning validation studies, a step the agency said is required to demonstrate consistent cleaning effectiveness.
The inspection also identified deficiencies in production and process controls. FDA said Nubratori modified vial filling configurations for two sterile injectable products — Lidocidex I and Lidomar — without conducting appropriate process validation. Investigators noted that the company’s risk assessment did not adequately evaluate critical factors such as sterility assurance, filling dynamics, and aseptic manipulation techniques. The agency said that media fill studies alone were improperly used as a substitute for full process validation with actual drug products.
In a third major observation, FDA investigators said Nubratori lacked adequate written procedures to prevent microbiological contamination of sterile drugs. The agency cited deficiencies in airflow smoke studies and described practices observed during compounding that could disrupt unidirectional airflow in laminar airflow hoods. Inspectors reported seeing personnel prepare environmental monitoring plates inside critical aseptic areas, including opening packaging and labeling plates with non-sterile markers, actions the FDA said introduced unnecessary contamination risks.
