Cerus Corporation Announces Receipt of CE Mark for Next-Generation INTERCEPT Illumination Device (INT200)

Regulatory Approval Allows Company to Initiate Commercialization of the Illumination Device throughout the European Union

Cerus Corporation (NASDAQ:CERS) announced today the CE mark approval of its next-generation LED-based illumination device, or the INT200, for the INTERCEPT Blood System for platelets and plasma under the European Union (EU) Medical Device Regulation (MDR). This approval allows Cerus to market the INT200 throughout the EU and in other regions that recognize the CE mark. Some countries may require additional in-country regulatory approval prior to commercialization. With the receipt of CE mark approvals of the INTERCEPT processing sets for platelets and plasma under the MDR in 2023, today's announced approval completes the authorization of the INTERCEPT Blood System for both platelets and plasma within the EU MDR framework.

"We are delighted to achieve this important commercial milestone. We believe the INT200 will be the foundational platform for geographic expansion and future growth of the INTERCEPT business," said Obi Greenman, Cerus' president and chief executive officer. "Today's news also demonstrates our continued commitment to customer-centric innovation for the global transfusion medicine community."

"Taking into account feedback received from our customers, we designed the INT200 to provide a significantly improved user experience and operational benefits through enhanced physical design and a novel software interface while maintaining compatibility with the same disposable processing sets and pathogen inactivation process currently in use," said Vivek Jayaraman, Cerus' chief operating officer. "Critically, we believe the INT200 will provide blood centers with the robust and reliable pathogen inactivation platform that they have come to expect from Cerus. We look forward to supporting our existing customers as they transition to this new device over the next few years as well as new customers as INTERCEPT is introduced in additional geographies."

The CE mark is the first regulatory approval received for Cerus' next-generation illuminator. The Company continues to plan for additional regulatory submissions over the next several years, and future innovation of the INTERCEPT platelet and plasma systems will utilize the INT200.
