PARSIPPANY, NJ, Sept. 01, 2022 (GLOBE NEWSWIRE) -- Interpace Biosciences, Inc. (“Interpace” or the “Company”) (OTCQX: IDXG), a fully integrated commercial company that provides clinically relevant molecular diagnostic tests and pathology services for improved patient diagnosis and management, today announced new clinical validation data for their thyroid cancer test platform which is comprised of a mutation panel (ThyGeNEXT®) and a microRNA (miRNA) risk classifier. The new data demonstrates that the addition of miRNA pairwise expression profiling (ThyraMIR®v2) provides clinically and statistically superior risk stratification of indeterminate thyroid nodules (ITN) beyond that of the algorithmic classification analysis provided by the original ThyraMIR® assay.
ThyraMIRv2 was developed and validated in a fully blinded cohort (n=197) from a previous retrospective validation study. The new data analysis revealed improvement in the number of true negative results and reduction of false positive results with a subsequent improvement in the specificity and PPV at positive threshold, while preserving a high sensitivity and NPV. The ROC AUC increased from 0.85 to 0.97 (p<0.001), and the diagnostic accuracy at the positive threshold increased significantly (p<0.05) from 83% (CI, 76-88) to 93% (CI, 89-96). ThyraMIRv2 optimized risk stratification of nodules with RAS-like (weak driver) mutations, minimally invasive follicular carcinomas, low-grade PTC, and Hürthle cell predominant nodules—providing significant improvement in test accuracy and the highest NPV and PPV of commercially available tests. The study has recently been published in THYROID®, the leading peer-reviewed journal for original research on thyroid cancer, and can also be accessed by visiting www.thyroiddx.com/pairwise.
Dr. Syd Finkelstein, Chief Scientific Officer of Interpace Diagnostics, commented that “miRNA analysis may also reduce the risk of RNA sampling error because miRNAs can migrate throughout the thyroid nodule. As a result, they may be less affected by spatial variability than the distribution of cells with DNA mutations.“
Further commenting was Dr. Carl Malchoff, Professor Emeritus, Medicine/Endocrinology, Founder of the Endocrine Neoplasia Program at UConn Health, and a co-author of the manuscript, “The addition of pairwise microRNA expression profiling represents a clinically important development in precision molecular diagnosis of indeterminate thyroid nodules. For 87% of samples, the positive and negative predictive values are ≥90% across a broad range of cancer prevalence (16% to 84%). Furthermore, as with earlier versions, this assay is performed using fresh FNA samples or diagnostic cytology slides, eliminating the need for an additional biopsy, refrigerated storage, or special shipping.”
Tom Burnell, PhD, President and CEO of Interpace Biosciences, added: “Mutational analysis alone is often insufficient to accurately “rule-in” or “rule-out” malignancy in indeterminate thyroid nodules. We have previously demonstrated the utility of pairwise miRNA analysis in the diagnosis of medullary thyroid cancer and are excited to be able to bring this more precise risk estimation to clinicians, who must integrate various risks and benefits when deciding for or against surgery.” He further stated, “The diagnosis and prognosis of thyroid and other cancers aligns fully to the Interpace corporate goal of improving healthcare by enabling personalized medicine.”
About Interpace Biosciences
Interpace Biosciences is an emerging leader in enabling personalized medicine, offering specialized services along the therapeutic value chain from early diagnosis and prognostic planning to targeted therapeutic applications.
Clinical services, through Interpace Diagnostics, provides clinically useful molecular diagnostic tests, bioinformatics and pathology services for evaluating risk of cancer by leveraging the latest technology in personalized medicine for improved patient diagnosis and management. Interpace has five commercialized molecular tests and one test in a clinical evaluation program (CEP): PancraGEN® for the diagnosis and prognosis of pancreatic cancer from pancreatic cysts; PanDNA®, a “molecular only” version of PancraGEN that provides physicians a snapshot of a limited number of factors; ThyGeNEXT® for the diagnosis of thyroid cancer from thyroid nodules utilizing a next generation sequencing assay; ThyraMIR®v2 ,used in combination with ThyGeNEXT®, for the diagnosis of thyroid cancer utilizing a proprietary microRNA pairwise expression along with algorithmic classification, and RespriDX® that differentiates lung cancer of primary versus metastatic origin. In addition, BarreGEN®, a molecular based assay that helps resolve the risk of progression of Barrett’s Esophagus to esophageal cancer, is currently in a CEP, whereby we gather information from physicians using BarreGEN to assist us in gathering clinical evidence relative to the safety and performance of the test and also providing data that will potentially support payer reimbursement.
