ProPhase Labs Announces Successful Study Demonstrating Performance of BE-Smart™ Test in Detecting Esophageal Cancer

BE-Smart represents a significant advance in diagnosis and management of Esophageal disease that affects an estimated 60 million people in the United States

Study shows >95% success rate, validating BE-Smart for use with esophageal brush cytology.

UNIONDALE, NY, June 17, 2025 (GLOBE NEWSWIRE) -- ProPhase Labs Inc. (NASDAQ:PRPH), (the "Company" or "ProPhase") a next generation biotech, genomics and consumer products company, today announced the successful completion of a key validation study evaluating the performance of the BE-Smart^™ molecular diagnostic test compatibility with samples obtained from esophageal brush cytology. The study demonstrated BE-Smart^™ achieved greater than a 95% technical success rate, confirming the BE-Smart's ability to reliably and accurately detect our panel of biomarkers, designed to assess progression risk in Barrett's esophagus and other distal esophageal conditions. Prophase will now move to accelerated commercialization of BE-Smart^™ with expected clinical launch in the next 2-3 quarters.

BE-Smart uses a proprietary panel of biomarkers and a multi-modal analysis method which together significantly increase detection of deadly cancer cells in one of the fastest growing cancer indications, esophageal denocarcinoma cancer or "EAC". EAC has a 5-year mortality rate of over 79% and surged in annual incidence over 750% since the 1970s. BE-Smart represents a technical advance in detection and prognosis which has the potential to change cost and outcomes for the large population affected by GERD, Barrett's and EAC globally.

"The ability to run BE-Smart on brush biopsy samples opens the door to much broader clinical use," said Ted Karkus, CEO at ProPhase Labs. "Many leading molecular diagnostics cannot be used with brush biopsies. BE-Smart now stands apart as the only advanced molecular test designed to work with both forceps biopsies and brush-based tissue collection. We are now working toward commercialization as a laboratory developed test (LDT) with a target market of roughly $10 billion dollars, representing an exciting future for our Company."

The dual capability of BE-Smart now validated to analyze both "pinch" and "brush" standard of care biopsies enables a powerful tool for comprehensive esophageal disease surveillance and clinical management. Pinch biopsies enable detailed analysis of specific areas, while brush biopsies gather a wider sample of epithelial cells, improving detection of disease across broader regions. Importantly, BE-Smart is commercially and clinically compatible with both of these broadly used approaches making it a dynamic and one-of-a-kind test.

Brush biopsies are rapidly emerging into mainstream clinical practice due to decreased cost and possibility of health complications associated with forceps biopsies. U.S. endoscopists perform approximately 6-7 million upper endoscopies (EGDs) each year, the majority of which still rely on traditional forceps biopsies alone. However, forceps sampling can miss up to 50% of focal areas of Barrett's esophagus, particularly when the disease is patchy or limited to the squamous epithelium.

This shift toward brush biopsies is driven by their improved diagnostic yield and safety profile, addressing some of the limitations of traditional forceps biopsies. As clinical evidence mounts, these non-invasive techniques are gaining traction in both the U.S. and abroad, transforming the landscape of esophageal diagnostics. With expanded payer coverage now reaching over 73 million U.S. lives, and inclusion in leading gastroenterology guidelines, brush biopsies are increasingly recognized for their ability to capture a broader, more representative cell population compared to forceps alone.

Brush biopsies continue to grow in popularity among gastroenterologists and endoscopists, particularly for patients with GERD, Barrett's esophagus, and other distal esophageal disorders. BE-Smart has been designed as the ideal molecular add-on testing platform for improving cancer risk stratification and disease monitoring. Improved measurement ability addresses the critical unmet need of early detection, treatment and improved outcomes.
