New Lynx Dx Urine Test Outperforms MRI in Identifying Prostate Cancer Upgrading During Active Surveillance

Clinical Validation Study Supports a Non-Invasive Monitoring Approach Where MPS2-AS Accurately Guides the Need for Surveillance Biopsies

ANN ARBOR, Mich., May 5, 2026 /PRNewswire/ -- Lynx Dx, a leader in innovative diagnostic solutions, announced today the validation of MyProstateScore 2.0 – Active Surveillance (MPS2-AS), the company's latest breakthrough and the first non-invasive urine-based assay designed to guide biopsy decisions in men with Grade Group (GG) 1 prostate cancer. In a multisite external validation study published in The Journal of Urology, the test outperformed multiparametric MRI (mpMRI) in biopsy decision-making during active surveillance.

Unmet Need
Active surveillance is widely used for men with low-risk prostate cancer, but existing tools have important limitations and monitoring relies on repeated biopsies that burden patients and practices. MPS2-AS was developed as a more patient-friendly, non-invasive approach to help determine when a biopsy may or may not be necessary.

"Active surveillance works best when clinicians can reliably identify the patients who need a biopsy while sparing those who do not," said Spencer Heaton, MD, CMO at Lynx Dx. "MPS2-AS is a promising non-invasive tool that helps reduce the burden of repeat biopsies, personalize monitoring, and support more confident decision-making for men living with low-risk prostate cancer."

Validated Accuracy, Unprecedented Flexibility
MPS2-AS provides personalized risk estimates to help urologists and patients make more informed, individualized biopsy decisions during active surveillance. Published data in The Journal of Urology demonstrated that MPS2-AS outperformed mpMRI in a multisite validation study for detecting upgrading and could have avoided up to 64% of unnecessary biopsies. The test showed strong performance across clinically important endpoints, delivering 97% sensitivity and 99% NPV for GG≥3 upgrading, and 95% sensitivity and 92% NPV for GG≥2 upgrading.

About MyProstateScore 2.0 – Active Surveillance (MPS2-AS)
MPS2-AS is the first validated urine test designed to help guide biopsy decision-making for men with GG1 prostate cancer by providing personalized risk estimates for upgrading to both GG≥3 and GG≥2 disease, supporting more individualized, patient-friendly monitoring to help reduce unnecessary biopsies. MPS2-AS builds on the science behind the commercially available MyProstateScore 2.0, which supports biopsy decision-making before diagnosis. Similar to MPS2, MPS2-AS will fit a convenient at-home or in-office collection process, without the need for DRE or temperature-controlled shipping, expanding access and flexibility for men undergoing long-term surveillance.

Lynx Dx plans to make MPS2-AS available with Medicare coverage and will announce additional launch details at LynxDx.com/ActiveSurveillance.
