Warning Letter: Lack of security for electronic data (ucm197966)

Your firm has not exercised appropriate controls over computer or related systems to assure that changes in master production and control records or other records are instituted only by authorized personnel [21 CFR 211.68(b)].

For example, your firm lacks systems to ensure that all electronic data generated in your Quality Control laboratory is secure and remains unaltered. All analysts have system administrator privileges that allow them to modify, overwrite, and delete original raw data files on the [redacted] used [redacted] in the High Performance Liquid Chromatography (HPLC) units. There are no procedures that address the security measures in place for generation and modification of electronic data files for these instruments used for raw material, in-process, finished product and stability testing. In addition, your firm’s review of laboratory data does not include a review of an audit trail or revision history to determine if unapproved changes have been made.
