FDA Warning Letter: Pest Activity, Water Leaks, and Misuse of QC Laboratory in U.S. Drug Manufacturing Facility
Recommendation
Tuesday, 14 January 2025 13.00 - 17.30 h
On 29 October 2024, the U.S. Food and Drug Administration (FDA) has published a Warning Letter dated 21 October 2024. The document goes back to an inspection performed earlier this year at a manufacturer of over-the-counter (OTC) topical drug products in North Carolina.
The Warning Letter summarizes a couple of significant violations of Current Good Manufacturing Practice (CGMP) regulations for finished pharmaceuticals
Condition of the Laboratory
The initial observation already says a lot about the condition of the buildings and facilities, especially the laboratory. The authority writes: "Our investigator observed pest activity in your raw material storage area, and evidence of water leaks and missing ceiling tiles in your drug manufacturing area. In addition, our investigator observed that your quality control (QC) laboratory was used by employees for meal preparation, dishwashing, and storage of soiled employee garments."
This misuse of the laboratory environment poses a high risk of contamination and compromises the reliability of product testing and quality control procedures. As the company failed to maintain clean and sanitary conditions in their manufacturing areas and was unable to provide sufficient measures to improve the condition in its response to the inspection report, the FDA is now demanding a series of measures, including:
- A detailled corrective action and preventive action (CAPA) plan
- Creation of detailed procedures
- A risk assessment for all drug products distributed to the U.S. market
Laboratory Testing and Stability Testing Program
The company did not conduct appropriate laboratory tests for each batch of drug product to ensure conformance to specifications, including the identity and strength of active ingredients and microbial contamination. This oversight meant that products were released into the U.S. market without sufficient proof of their safety and effectiveness.
Furthermore, the firm failed to establish and maintain an ongoing stability testing program to support the labeled expiry of the distributed drug products. The FDA concludes: "There is no assurance that [the] drug products will remain acceptable throughout their labeled expiry period without an ongoing stability program."
Unapproved New Drug Violations and Misbranded Drug Violations
Another focus of the FDA's Warning Letter was the violation concerning the marketing of unapproved new drugs. Some of the company's products were found to be unapproved new drugs, violating various sections of the Federal Food, Drug, and Cosmetic Act. The Warning Letter also addressed issues related to misbranding under section 502 of the FD&C Act. The FDA explains in detail why the products did not meet the “generally recognized as safe and effective” (GRASE) standard required for OTC drugs
Conclusion
The FDA warned that failure to promptly address these issues could result in severe regulatory actions, including product seizures, injunctions, and restrictions on new application approvals. The letter emphasized that the company's executive management must oversee and ensure compliance with CGMP requirements.
