CGMP Deviations at Mexican Signa Facility
A 12/16-12/20/19 FDA inspection at the Signa SA de CV facility in Toluca De Lerdo, Mexico, found significant deviations from current good manufacturing practice (CGMP) regulations for active pharmaceutical ingredients. A 7/14 Warning Letter says the specific violation was failing to adequately investigate out-of-specification results and to implement appropriate corrective action.
The letter acknowledges that Signa initiated efforts to remediate and improve its investigation programs and says the company response lacked adequate details on the remediation approach and the scope of its assessment was insufficient.
FDA notes that it cited similar CGMP deviations at other facilities in the Canadian company’s network and said the repeated failure at multiple sites demonstrate that management oversight and control over the manufacture of drugs is inadequate.
Signa was told to respond with a list of specific steps taken since the inspection to correct the deviations and prevent their recurrence, with a schedule for completing the steps.
