NucleoBio and PreCheck Health Services Announce Strategic Collaboration to Advance Non-Invasive Prostate Cancer Testing

September 18, 2025 at 06:00 AM EDT

NucleoBio, Corp., a leading biotechnology innovator in precision oncology diagnostics, and PreCheck Health Services, a high-complexity CLIA-certified and CAP-accredited clinical laboratory, today announced a strategic collaboration to support clinical development and processing of the proprietary Prostac™ assay. This partnership aims to enable future application of the test across a broader clinical setting, supporting ongoing research and validation efforts for early detection and risk stratification in prostate cancer.

The collaboration will leverage PreCheck’s advanced laboratory infrastructure and operational expertise to further validate and process Prostac™—a qPCR-based composite assay developed by NucleoBio to assess expression levels of specific long non-coding RNA biomarkers derived from the PVT1 gene.

Prostac™: A Novel Biomarker-Based Composite Score

At the core of this collaboration is Prostac™, a composite diagnostic score derived from the quantification of PVT1 exons 4A, 4B, and 9. These specific exons are significantly overexpressed in prostate cancer tissue in men of African ancestry and have demonstrated high accuracy in both preclinical and clinical models for distinguishing malignant from non-malignant samples.

Prostac™ integrates the measured expression levels using supervised machine learning techniques—specifically, support vector classifiers—to generate a score that accurately predicts the likelihood of prostate cancer. The assay has shown promising early results, with 100% sensitivity and specificity in preliminary in vitro evaluations using prostate epithelial and prostate cancer cell lines.

“Combining novel molecular markers with mathematical oncology through machine learning allows for robust and scalable diagnostic solutions,” stated Dr. Olorunseun Ogunwobi, co-developer of Prostac™ and co-founder of NucleoBio. “The ability to accurately identify early and aggressive cases of prostate cancer—non-invasively—represents a paradigm shift.”

“The process of moving scientific findings or innovations from research institutions into the commercial sector and generating social impact is the main goal of any tech transfer,” says Neeti Mitra, Associate Director, CUNY Technology Commercialization Office, from where the core technology was licensed. “The vision of CUNY and NucleoBio was same from the beginning; to turn cutting edge research into market-ready products. Hence, we are excited about this collaboration between NucleoBio and Precheck Health Services.”

Enabling Scalable, CLIA-Compliant Processing

PreCheck Health Services will serve as the exclusive laboratory processing facility for clinical samples analyzed using the Prostac™ assay during its validation phase. Leveraging PreCheck’s robust genetic testing platform and automation infrastructure, this collaboration ensures consistency, compliance, and scalability under CLIA and CAP regulations.

“As a clinical lab focused on precision medicine, we are proud to support a next-generation assay like Prostac™,” said Francis Pittilloni, Chief Operating Officer at PreCheck Health Services. “This initiative exemplifies our mission to bring forward validated, clinically actionable genetic tests that meet the highest standards of scientific and operational integrity.”

The assay will initially be utilized for research use only (RUO) and early validation studies. Both companies affirm their commitment to maintaining full compliance with FDA and CMS guidelines concerning laboratory-developed tests (LDTs), including appropriate use disclosures.

Addressing a Critical Clinical Gap

Prostate cancer remains the most diagnosed solid tumor among men globally, with significant racial disparities in incidence and mortality. While PSA testing remains the current standard, its limitations—high false-positive rates, lack of specificity, and poor predictive value—have underscored the need for new biomarkers. “This is improved medical care,” says Neeti Mitra, Associate Director CUNY TCO, “transferring medical technologies like this with the future goal of bringing good quality healthcare to remote areas, reducing mortality and improving well-being. It will revolutionize treatment, making healthcare more personalized and accessible.”

According to studies published in Frontiers in Oncology, PLOS ONE, and Genes, the PVT1 locus, particularly exon 9, plays a key oncogenic role in the initiation and progression of prostate cancer. Its upregulation correlates with castration resistance, increased cell proliferation, and poor prognosis.

The Prostac™ composite score is being developed to address this unmet need—offering clinicians a more precise and biologically relevant indicator of disease activity, with the potential to reduce unnecessary biopsies and enhance early intervention.
