Revised procedure for coordinating GMP inspections of centrally authorised products

Version 3 of the guideline, adopted in April 2026 and entering into force on 10 September 2026, describes EMA coordination of GMP inspections conducted by EEA competent authorities for centrally authorised products. It covers pre-approval inspections, for-cause inspections and routine risk-based re-inspections, including inspection triggers, authority selection, preparation, site contacts and report submission through IRIS. The revision clarifies that, where a Supporting Authority is unnecessary, one Authority may perform both leading and supporting roles. Applicants should identify proposed manufacturing, testing and batch-release sites before submission, and all listed sites should be inspection-ready and compliant with EU or equivalent GMP from submission.

FDA Warning Letter: PReye cited for unsuitable aseptic processing and inadequate quality systems

FDA states that its March 17–19, 2026, inspection of PReye’s drug manufacturing facility found significant finished-pharmaceutical CGMP violations. The firm manually filled multiple drug products from bulk liquid using a small flow hood on an office desk. FDA observed that the hood was neither certified nor qualified and was located in unclassified office space without HEPA filtration. FDA stated that these conditions lacked appropriate facilities, equipment, and process controls to protect products from microbiological contamination. FDA also found no quality unit function or written procedures defining its responsibilities. Basic procedures were absent, including complaint review, supplier qualification, release testing, change management, cleaning, disinfection, and deviation handling. FDA further reported missing batch numbers for sterile ophthalmic products manufactured since 2024, impairing traceability. The firm committed to cease U.S. manufacturing and distribution of PReye Vitamin SEE; it later voluntarily recalled the product because sterility testing had not been performed.

The guidance sets out product information, patient-impact assessment, supply-chain mapping, shortage history, risk classification and proportionate management measures. It also identifies additional crisis-related information for listed critical medicines, including production and supply capacity, alternative sites and minimum stock levels. Plans should be updated after relevant changes and may form part of annual product quality review.
