Annex 1 Demystified:
Your Top Questions Answered

Annex 1 Made Simple:
Answers to Your Most Asked Questions

Annex 1 sets EU standards for sterile drug manufacturing, revised in 2022 to align globally. Contamination control is now more strategic, with Annex 1 emphasizing CCS, expanded cleanroom guidance, and QRM to drive proactive, integrated monitoring and compliance.

This paper addresses key questions raised during our Annex 1 webinar, grouped into the following categories:

  • Limits, Alerts, and Alarms

  • Preparation and Qualification (CCS)

  • Continuous Monitoring

  • Specific Technologies

  • Specific Industries

  • Gear and Personnel

  • Recovery

  • Miscellaneous

Examples of questions covered: 

  • Why was the limit of 0.5 micron particles raised from 20 particles/m3 to 29 particles/m3 in this revision?
  • How do you prepare to implement the Contamination Control Strategy (CCS)?
  • Is it necessary to have a continuous monitoring system for particles in Grade A if we can justify in the CCS/QRM that a continuous one is not necessary?
  • How does Annex 1 apply to Cell and Gene Therapy?
  • Annex 1 refers to ISO 14644 which says the recovery test is not recommended for ISO 8 and 9? This would slightly contradict the Annex 1’s requirement. Could you explain?
  • ….and more!
