Study Demonstrated a Sensitivity of 100% and Specificity of 95% 

BERKELEY, US and MAINZ, Germany – October 8, 2025 - Mainz Biomed N.V. (NASDAQ:MYNZ) (“Mainz Biomed” or the “Company”), a molecular genetics diagnostic company specializing in the early detection of cancer, announces positive topline results from its feasibility study, examining a non-invasive blood-based screening test for the early detection of pancreatic cancer, initiated earlier this year. The study confirmed the strong clinical accuracy and utility of licensed proprietary biomarkers from Liquid Biosciences for developing an innovative screening test for pancreatic cancer. Researchers evaluated 18 licensed biomarkers across multiple candidate panels to streamline assay complexity. The leading panel achieved 100% sensitivity and 95% specificity, successfully distinguishing pancreatic cancer patients from healthy controls in a 30-subject cohort, reflecting different stages of the disease as well as precursors.

These findings are consistent with the strong performance previously demonstrated in discovery and validation datasets, which achieved 95% sensitivity and 98% specificity earlier this year. The reproducibility of these results further strengthens confidence in the robustness of the biomarker panel and its potential as the foundation of a reliable, non-invasive screening test.

Importantly, the algorithm developed by Liquid Biosciences not only distinguished pancreatic cancer from healthy controls but also successfully detected precancerous lesions that have the potential to develop into pancreatic cancer if left untreated. The ability to identify these lesions through a blood test opens the door to monitoring at-risk individuals, intervening earlier in the disease process, and ultimately reducing the incidence and mortality associated with pancreatic cancer.
