Leading the Way in Annex 1 Compliance and Innovation in Freeze-Drying Technology

August 24, 2024

In a proactive move to adhere to the updated Annex 1 guidelines, GEA Pharma & Healthcare has been setting the benchmark for compliance and innovation in freeze-drying technology. As the new regulations come into effect this August, GEA has long been prepared, seamlessly integrating the changes to ensure that both current and future projects meet the stringent requirements set forth by the European Commission’s revised good manufacturing practice (GMP) guidelines.

Staying Ahead of Compliance

"Many of the revisions in Annex 1 are new to the guidelines but not new to GEA," explains Jessica Wagner, Validation Engineer at GEA Pharma & Healthcare. For instance, one of the new stipulations requires users to detect any leaks that could compromise product integrity. GEA addresses this with its state-of-the-art LYOPLUS® mass spectrometer, which is capable of detecting various types of silicone oil and hydraulic fluids. This device also monitors moisture levels in the freeze-drying chamber, reducing leak detection times to just one hour.

GEA’s commitment to minimizing contamination risks is further demonstrated through its ALUS® Automatic Loading and Unloading Systems. By reducing human intervention, these systems not only cut down processing times and boost productivity but also lower operational costs via advanced monitoring technologies.

Looking ahead, GEA is embracing the rise of automation with the introduction of the ALUS Robot. This innovation aligns with industry trends toward enhanced product protection and reduced operator intervention. The robotic system ensures flawless product handling by using nests to prevent container falls, minimize glass-on-glass contact, and achieve processing speeds of up to 1000 vials per minute in larger systems. Additionally, GEA is staying ahead of compliance requirements by offering Contamination Control Strategy (CCS) documents, including CFD studies, GMP risk analysis, and rationale-based monitoring concepts.

Meeting and Exceeding Annex 1 Standards

Jessica notes that while Annex 1 now defines current best practices, GEA has long been operating at these high standards. The only significant updates involved adding a second temperature sensor and the option to install a remote camera for observing production activities from outside grade A and B areas.

Annex 1 mandates that "freeze-drying systems should be monitored for temperature, pressure, and time at appropriate locations during routine use to ensure all areas are effectively and reproducibly sterilized." GEA has made this a default setting for its machines, ensuring that all updates were relatively minor yet crucial for compliance.

Retrofitting and Upgrading Existing Equipment

In conclusion, Jessica affirms that GEA freeze dryers are fully compliant with Annex 1 and that older machines can be retrofitted to meet the new standards. "Whatever the requirements of Annex 1, whether new or updated, GEA has a solution," she says. "We’ve implemented remote cameras, added sterilize-in-place (SIP) safeguards, and are continuously developing robotic applications to enhance our technology. This commitment goes beyond compliance; it's about serving our customers in the best possible way."

GEA also offers to update third-party equipment to ensure complete compliance with the new regulations. "Don’t hesitate to contact us for a full assessment of your current needs or future requirements," Jessica advises. "With the legislation now in force, it's crucial to act promptly to ensure you’re fully compliant."
