As the landscape of sterilization methods evolves, the FDA has taken a significant step by updating its guidance to include vaporized hydrogen peroxide (VHP) as an acceptable method for the submission and review of sterility information in Premarket Notification 510(k) submissions. 

This update, detailed in the FDA’s recent document, “Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile Guidance for Industry and Food and Drug Administration Staff” marks a pivotal moment for the sterilization industry, recognizing the extensive history and efficacy of peroxide-based sterilization methods.

Additionally, recent efforts have been made to implement ISO 22441:2022, establishing a standardized framework for validating VHP processes. This development is expected to streamline validation procedures and reduce the regulatory burden associated with alternatives to ethylene oxide (EO).

VHP, widely utilized in compact, rigid chambers for sterilizing both single-use and reusable medical devices, offers notable advantages such as short cycle times and low operating temperatures. However, challenges persist, including the meticulous management of residual sterilant to ensure patient and operator safety, as well as limitations in material penetration and compatibility, particularly with common cellulose-based items such as paper instructions for use (IFUs) and common product packaging materials - namely cardboard. In short - the typical approach to packaging and shipping devices in large quantities - palletized cardboard shipper boxes - are non-compatible.

In light of these considerations, electron beam (E-beam) sterilization remains the most compelling volume alternative, from a material-compatibility perspective, to EO. While E-Beam will not be suitable for all EO applications, it offers better overall material compatibility than other mature and high-volume modalities including gamma, steam, and dry heat. With its established Category A classification and broader materials compatibility compared to VHP, E-beam offers a solution for processing items with IFUs and packaging. Unlike VHP, E-beam technology boasts the capability to sterilize products at an industrial scale, making it suitable for a wide range of medical device manufacturers.

"At NextBeam, we are dedicated to providing innovative solutions that meet the evolving needs of the medical device industry," commented Andrew Patton, Founder & CEO. "If you are seeking a terminal sterilization method as an alternative to EO, we invite you to explore the potential of E-beam technology. Our team is equipped to assess your product materials and design to determine if E-beam sterilization is the right fit for your needs."
