BERKELEY, Calif. and MAINZ, Germany, Sept. 02, 2025 — Mainz Biomed N.V. (NASDAQ:MYNZ) (“Mainz Biomed” or the “Company”), a molecular genetics diagnostic company specializing in the early detection of cancer, today announced that ColoAlert® has achieved official registration with the Medicines and Healthcare products Regulatory Agency (MHRA), thereby authorizing its marketing in the United Kingdom.

This achievement follows the technology partnership unveiled earlier this year with EDX Medical Group plc, a prominent UK laboratory, and signifies a crucial advance towards making Mainz Biomed’s DNA-based colorectal cancer (CRC) screening test, ColoAlert, broadly accessible to patients across the nation.

Colorectal cancer stands as the fourth most common cancer in the UK, with roughly 44,000 new diagnoses reported annually. ColoAlert offers a non-invasive method for CRC screening by identifying DNA biomarkers in stool samples. The test aims to complement the existing Bowel Cancer Screening Program, which currently invites approximately 4 million individuals aged 50 to 74 for an annual FIT test, by introducing an additional, convenient option that could enhance participation.

“With this approval, ColoAlert is now cleared for use throughout the UK,” stated Guido Baechler, CEO of Mainz Biomed. “This regulatory milestone enables our UK laboratory partner to provide a dependable and user-friendly test to a large populace, supporting our mutual objective of increasing engagement in preventative screening and, ultimately, preserving more lives.”

The UK approval for ColoAlert highlights Mainz Biomed’s dedication to broadening access to advanced diagnostic options for early cancer identification. By furnishing healthcare professionals and patients with an extra resource for colorectal cancer prevention, the Company is progressing its mission to tackle a primary global cause of cancer-related deaths.
