Mainz Biomed Announces Commercial Launch of ColoAlert® in Switzerland

Company Provides Update on eAArly DETECT 2 Study

BERKELEY, Calif. and MAINZ, Germany, Sept. 23, 2025 (GLOBE NEWSWIRE) — Mainz Biomed N.V. (NASDAQ:MYNZ) (“Mainz Biomed” or the “Company”), a molecular genetics diagnostic company specializing in the early detection of cancer, is pleased to announce the commercial launch of its flagship product, ColoAlert®, in Switzerland.

This milestone comes as the result of several key achievements. Earlier this year, Mainz Biomed signed a strategic partnership with labor team w ag (“labor team”), one of the country’s leading diagnostic laboratories. This collaboration provides a strong foundation for ColoAlert’s successful introduction, ensuring that patients and physicians across Switzerland will have access to the test through an established and trusted network.

Following this, Swissmedic, the Swiss authority responsible for therapeutic product regulation, granted official registration and marketing approval for ColoAlert®. This authorization enables the test to be distributed in Switzerland and marks an important regulatory step toward expanding patient access to innovative colorectal cancer screening solutions.

In addition, Mainz Biomed successfully completed a comprehensive technology transfer with labor team, enabling the laboratory to process and analyze ColoAlert® samples directly at its state-of-the-art facility in Goldach, Switzerland. This local implementation not only ensures operational efficiency but also guarantees that Swiss patients benefit from high-quality diagnostics performed within their own healthcare system.

Together, these accomplishments have paved the way for the commercial launch of ColoAlert®, making the test available to patients and healthcare providers throughout Switzerland.

The Company continues to make progress on recruitment for its 2,000 patient, average risk population study. With its goal of completing enrollment by the end of 2025, management has decided not to pause the study for an interim readout, but instead completing enrollment, analysis, and read out on the completed study.
