ProPhase Labs Announces Collaboration with mProbe, Inc. and Mayo Clinic for the Continuing Development of BE-Smart Esophageal Pre-Cancer Diagnostic Screening Test

Company Outlines BE-Smart Test Roadmap for Commercialization in the U.S.

Company in Early Stages of Exploring Development for Commercialization in Other Countries

Garden City, NY, March 1, 2023 (GLOBE NEWSWIRE) — ProPhase Labs, Inc. (NASDAQ: PRPH) (“ProPhase”), a growth oriented and diversified diagnostics, genomics and biotech company, today announced a collaboration with mProbe, Inc. (“mProbe”), a precision health and medicine company utilizing clinical proteomics in the oncology space, and Dr. Christopher Hartley of Mayo Clinic for the continued development of its BE-Smart Esophageal Pre-Cancer Diagnostic Screening test.

mProbe plans to continue testing specimens provided by the Mayo Clinic in the first quarter of 2023. ProPhase Labs intends to pursue initial commercialization of the BE-Smart test as a laboratory developed test (LDT) and for research use only (RUO) in the third quarter of 2023, once 500 specimens have been tested by mProbe. Clinical validation of the BE-Smart test for mass spectrometry for non-insurance payers is estimated to commence in the third quarter of 2023. Full commercialization backed by insurance is expected to commence by mid-2024.

The BE-Smart test has been previously tested on over 200 human samples to date by mProbe in conjunction with Dr. Christopher Hartley and Mayo Clinic and has shown an area under curve of greater than 99% in distinguishing highly impactful histologic classifications.^[1] The initial protein-histologic correlations have also been redemonstrated in an unrelated RNA sequencing data set. Additional pilot findings include 100% accuracy in predicting invasive carcinoma in biopsy specimens that were otherwise uninformative about invasion histologically. The assay’s performance in this regard was confirmed with subsequent resection or synchronous endoscopic ultrasound findings.

Ted Karkus, ProPhase Lab’s Chief Executive Officer, commented, “We are excited to announce this continued collaboration and outline our development and early commercialization strategy for the BE-Smart diagnostic test, which we believe could become an important and potentially lifesaving test. Approximately 83% of esophageal adenocarcinoma (EAC) patients die of this terrible disease within six months to five years of diagnosis.^[2] If diagnosed potentially years earlier with our diagnostic test, an ablation procedure may destroy the pre-cancerous cells before developing into cancer. With partners like mProbe and Dr. Hartley of the Mayo Clinic, we are optimistic that we can meet our commercialization goals for this potentially life-saving test. We are also in preliminary discussions to license, develop and ultimately commercialize our BE-Smart test in other countries.”

Mr. Karkus continued, “ProPhase is ahead of schedule in hiring an expert consultant to initiate its evaluation and cost benefit analysis toward obtaining CPT codes. The Company expects to pursue reimbursement rates in the range of $1,000 to $2,000 per test, based on CPT codes of similarly complex tests^[3] and with gross profit margins approaching 75% as volumes grow. Our initial target market is 2 million endoscopies performed annually on patients with Barrett’s esophagus, which equates to a $2 billion to $4 billion potential market just in the U.S. mProbe and Mayo Clinic aim to study 1,000 specimens in total by the end of 2023, which will enable ProPhase to pursue full commercialization as an LDT.”

ProPhase Labs has also begun to establish various touchpoints with key opinion leaders (KOLs) and will continue to do so throughout 2023 to increase awareness of the Company’s ongoing development of the BE-Smart test and lay the groundwork for its eventual adoption once fully validated and commercially available.

About the BE-Smart Test

The BE-Smart Esophageal Pre-Cancer Diagnostic Screening test is aimed at early detection of esophageal cancer. It has already been tested by an independent test lab, mProbe, Inc. on over 200 human samples and has shown an area under curve of greater than 99% in distinguishing highly impactful histologic classifications.^[1] ProPhase Labs plans to pursue initial commercialization of the BE-Smart test as an LDT and RUO. The goal of widespread adoption of the BE-Smart diagnostic test would allow health care providers to initiate potentially lifesaving early treatment processes such as an ablation procedure to remove the precancerous cells and could also significantly reduce unnecessary endoscopies.

(Nasdaq: PRPH) (“ProPhase”) is a growth oriented and diversified diagnostics, genomics and biotech company that seeks to leverage its CLIA lab services to provide whole genome sequencing and research direct to consumers and build a genomics database to be used for further research. The Company provides traditional CLIA molecular laboratory services, including COVID-19 testing. The Company also operates Pharmaloz, a rapidly growing contract manufacturing subsidiary, and offers the TK Supplements line of dietary supplements, which are distributed in food, drug, and mass stores throughout the country.

ProPhase Diagnostics, Inc., a wholly owned subsidiary of ProPhase, offers a broad array of clinical diagnostic and testing services at its CLIA certified laboratories including polymerase chain reaction (PCR) testing for SARS-CoV-2 (COVID-19) and Influenza A and Influenza B. Critical to COVID-19 testing, ProPhase Diagnostics provides fast turnaround times for results. ProPhase Diagnostics also offers best-in-class rapid antigen tests to broaden its COVID-19 testing beyond RT-PCR testing. The Company has announced plans for the expansion of the lab to include traditional clinical testing and genomics sequencing.

Nebula Genomics, a rapidly growing and wholly owned subsidiary of ProPhase, focuses on genomics sequencing and testing technologies, a comprehensive method for analyzing entire genomes, including the genes and chromosomes in DNA. The data obtained from genomic sequencing may help to identify inherited disorders and tendencies, help predict disease risk, help identify expected drug response, and characterize genetic mutations, including those that drive cancer progression. The Company currently offers Nebula Genomics whole genome sequencing products direct-to-consumer online, with plans to sell in food, drug and mass (FDM) stores and to provide testing for universities conducting genomic research.

ProPhase BioPharma, Inc. (PBIO), a wholly owned subsidiary of ProPhase, was formed for the licensing, development and commercialization of novel drugs and compounds.
