Allergan’s Ireland Plant Hit With 483 After Inspection

Share

FDA has cited multiple manufacturing and quality control deficiencies at a facility operated by Allergan Pharmaceuticals in Ireland following an inspection last year, according to a just-released agency inspection report.

The Form 483 outlines concerns spanning testing procedures, cleaning validation and environmental monitoring in aseptic areas. Among the observations, FDA investigators say the company’s examination and testing practices did not adequately ensure that drug products and in-process materials met specifications. Inspectors cite insufficiently defined rejection limits for visual inspections, noting that limits were set for individual defect types but not for total critical, major or minor defects.

The agency also flags gaps in laboratory controls, including the absence of written procedures for endotoxin testing of certain in-process and finished drug products, as well as a lack of documentation governing sample handling timelines and tracking.

In addition, FDA says cleaning validation had not been conducted for some equipment components that come into indirect contact with sterile products during filling operations, raising concerns about potential contamination risks. Inspectors also point to shortcomings in environmental monitoring practices in aseptic processing areas, including unclear procedures for incubation and reading of monitoring samples.

Additionally, the report notes deficiencies in shipping validation, including the lack of standard operating procedures for packaging quality control and stability samples sent to external testing facilities.
