Mainz Biomed and OncoVanguard8 Enter into Agreement to bring ColoAlert to South America

OncoVanguard8 is a leading service provider for innovative healthcare products for insurance companies operating in Peru, Colombia and Ecuador 

BERKELEY, US and MAINZ, Germany – November 18, 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 the signing of a Memorandum of Understanding (“MOU”) with OncoVanguard8, a distributor of oncological innovations. The collaboration aims to introduce ColoAlert®, a DNA-based colorectal cancer (CRC) screening test, to South America, starting with Peru.

Colorectal cancer continues to represent one of the most prevalent yet largely preventable cancer types on a global scale. In the three initial launch markets Peru, Colombia and Ecuador alone, approximately 17,000 new cases are diagnosed each year, highlighting the pressing demand for effective early detection and preventive strategies. The rollout of a DNA-based CRC screening solution presents a significant step forward, with the potential to markedly raise screening participation, facilitate timely diagnosis, and align seamlessly with national public health initiatives aimed at reducing CRC-related mortality and enhancing long-term population health outcomes.

In their common MOU, Mainz Biomed and OncoVanguard8 have outlined core commercial, legal and regulatory terms as well as the go-to-market strategy for the initial territory to be part of a final distribution agreement aimed to be signed within the next weeks.
