TEST:

ExoDx™ Prostate (IntelliScore) Test

While most exosomal biomarkers remain in early validation phases requiring comprehensive clinical development, the convergence of advancing analytical technologies, evolving regulatory frameworks, and collaborative research initiatives positions exosomes as promising tools for advancing precision medicine in leukemia. However, realistic timelines and sustained investment in methodological standardization remain essential for successful clinical translation.

"MDxHealth SA...today announced the closing of the ExoDx business acquisition from Bio-Techne Corporation, which includes the ExoDx Prostate test...On August 5, 2025, mdxhealth signed a definitive agreement to acquire Exosome Diagnostics, Inc. from Bio-Techne, including the ExoDx Prostate (EPI) test, CLIA-certified clinical laboratory and related assets. Total consideration for the acquisition is $15 million, with $5 million in stock paid at closing and $2.5 million to be paid annually over the following 4 years with 50% in cash and 50% in cash or stock at mdxhealth’s discretion."

Commercially-available, noninvasive biomarker tests consistently outperformed PSA and PSA-based risk calculators for detection of csPCa. Clinical use of these tests appears to substantially reduce the proportion of unnecessary biopsies performed, while maintaining detection of the vast majority of significant cancers.

Prostate cancer biomarkers improve risk stratification and may lower healthcare costs. However, variations in cost-effectiveness, reimbursement policies, and guideline recommendations limit widespread adoption. Prospective studies are needed to validate real-world cost savings and refine biomarker integration into clinical practice. Addressing financial and policy challenges is essential to ensure equitable access and maximize their impact on prostate cancer management.

By assessing genetic mutations (e.g. BRCA1, BRCA2 genes, single nucleotide polymorphism) or the presence of splice variants of the androgen receptor (ARV7), we are able to identify patients in whom the planned treatment may be expected to be ineffective and thus choose other treatment modalities. In the present review article, we offer a comprehensive overview of current diagnostic tests that find application in the diagnosis of early and advanced prostate cancer.

Based on these interim results, the ExoDx TM Prostate Test is valuable both as a standalone tool and when utilized alongside mpMRI to reduce unnecessary procedures and improve management decisions for men on AS. Also, test utilization provides an objective risk assessment and easy access for men considering AS protocols.

Conclusions In conclusion, an EPI test score > 31.47 was more sensitive and specific for biopsy-proven prostate cancer when compared to a PI-RADS score 3 or more. Hence, we may consider using EPI test either as an adjunct to MRI prostate to avoid unnecessary biopsies or in patients with contradication to MRI prostate.

Additionally, the review explores the role of tumor-associated microbiota in PCa, offering new insights into its potential contributions to disease understanding. By examining the latest advancements in PCa biomarkers, this review enhances understanding their roles in disease management.

This manuscript describes the characteristics and diagnostic performance of each biomarker alone and in combination with mpMRI, with the intension to provide a basis for decision-making in the diagnosis and treatment of HGPCa. Additionally, we explored the applicability of the combination protocol to the Asian population.

The contemporary literature further supports the proposed role of post-PSA biomarker testing to reduce the use of invasive biopsy while maintaining highly sensitive detection of GG ≥ 2 cancer. Questions remain regarding the optimal application of biomarkers in combination or in sequence with mpMRI.
