Findings extracted from the letter

Selected FDA passages, not the complete letter.

01
Your firm failed to conduct adequate investigations and take appropriate corrective action when a failure of a production batch or any component of the batch failed to meet any of its specifications (21 CFR 212.20(d)).
02
You failed to conduct adequate effectiveness checks for CAPAs to prevent recurrence.
03
You failed to adequately control your EM contact plates used to monitor your production operations.
04
Your firm failed to ensure adequate control of airflow in the ISO 5 critical aseptic processing area. Smoke studies conducted at your facility did not include a dynamic evaluation of LAFW or **(b)(4)** operations and therefore do not adequately demonstrate that unidirectional airflow effectively controls air quality during aseptic manufacturing.
05
You failed to adequately disinfect the exterior surfaces of the **(b)(4)** prior to aseptic manufacturing operations and failed to establish written procedures for the cleaning and disinfection of **(b)(4)** surfaces.
