FDA Cites SGS France Life Sciences Over Bioanalytical Method Validation

Share

FDA has cited SGS France Life Sciences following an 8/2025 inspection, identifying multiple deficiencies involving bioanalytical method validation, study documentation and adherence to standard operating procedures at the company's Saint-Benoît, France, facility. According to a just-posted three-page Form FDA 483, investigators documented four inspectional observations related to method validation and study sample activities for a redacted product or program.

The agency's primary observation stated that a chiral analytical method used in method validation lacked sufficient specificity to accurately measure low concentrations of the analyte in the presence of high concentrations of an interfering compound. FDA said a peak exceeding 20% of the lower limit of quantitation was consistently detected despite repeated efforts to identify the source of the interference, yet the method continued to be used to measure subject samples.

FDA also criticized the company's reporting practices, saying not all tested analytical sequences were disclosed in method validation and bioanalytical reports. Investigators cited multiple instances in which failed analytical runs were rejected and repeated, but the original failures, reasons for rejection and subsequent reinjections were omitted from the final reports. These included a 12/2022 method validation run with erratic internal standard signals and two 2024 study sample runs that failed because of a reconstitution error and carryover observed in a blank sample.

Additionally, investigators found that established standard operating procedures were not consistently followed. FDA said a study director overruled a technician's decision to reject a validation run that failed pre-established acceptance criteria without documenting the deviation required under the company's methodology SOP.
