Clinical Data Highlights the Utility of ThyGeNEXT® and ThyraMIR®
PARSIPPANY, NJ, Nov. 04, 2019 (GLOBE NEWSWIRE) -- Interpace Group (IDXG) Interpace Diagnostics announced today the publication of two peer-reviewed journal articles and one textbook chapter supporting the clinical utility of ThyGeNEXT® when used alone and in combination with ThyraMIR®.
The most recent article was published in Diagnostic Cytopathology in a paper called “Incremental Utility of Expanded Mutation Panel When Used in Combination with MicroRNA Classification in Indeterminate Thyroid Nodules”. The study is now published on the Diagnostic Cytopathology website at https://doi.org/10.1002/dc.24328 and compares results of ThyGenX®, Interpace’s first-generation mutation panel, with ThyGeNEXT®, Interpace’s expanded second-generation mutation panel, showing that the expanded panel provides additional utility when used in combination with ThyraMIR®, Interpace’s microRNA risk classifier. The study concludes that expansion of the panel increases detection of mutations and fusions strongly associated with malignancy and aggressive thyroid cancer, increasing the panel’s utility in surgical decision making. Furthermore, the panel expansion also increases detection of less aggressive mutations also associated with malignancy, where ThyraMIR® plays a key role in providing additional risk stratification.
An independent peer-reviewed journal article has been published in the Journal of Otolaryngology related to a study lead by Dr. Rick Payne from McGill University, Montreal, QC, Canada. The article entitled “Molecular Mutations as a Possible Factor for Determining Extent of Thyroid Surgery” concluded that markers in Interpace’s ThyGeNEXT® may be useful in identifying aggressive thyroid tumors, assisting in the planning and timing of surgery for patients.
In addition, Interpace’s pathologist, Dr. Tina Narick contributed to a chapter entitled “Application of Molecular Tests in Indeterminate Thyroid FNA” in the Atlas of Thyroid Cytopathology on Liquid-Based Preparations. The chapter reviews the performance and utility of molecular testing on thyroid aspirates and specifically includes detailed information on ThyGenNEXT® and ThyraMIR® performance, with discussion of various specimen types including cytology slides. Importantly, it describes results of a comparison between ThyGeNEXT® and ThyGenX®, indicating 100% concordance between test results and the identification of additional markers of aggressive cancer using ThyGeNEXT®,
According to Jack Stover, Interpace’s CEO, “These publications provide further evidence of the clinical utility of our molecular products for thyroid cancer.” In addition, he stated, “our accumulation of data helps validate our claims with insurance companies who are effectively the gate keepers for patients needing our expertise.”
About Thyroid Nodules, ThyGeNEXT® and ThyraMIR® Testing
According to the American Thyroid Association, approximately 20% of the 525,000 thyroid fine needle aspirations (FNAs) performed on an annual basis in the U.S. are indeterminate for malignancy based on standard cytological evaluation, and thus are candidates for ThyGeNEXT® and ThyraMIR®.
ThyGeNEXT® and ThyraMIR® reflex testing yields high predictive value in determining the presence and absence of cancer in thyroid nodules. The combination of both tests can improve risk stratification and surgical decision-making when standard cytopathology does not provide a clear diagnosis for the presence of cancer.
ThyGeNEXT® utilizes state-of-the-art next-generation sequencing (NGS) to identify more than 100 genetic alterations associated with papillary and follicular thyroid carcinomas, the two most common forms of thyroid cancer. ThyraMIR® is the first microRNA gene expression classifier. MicroRNAs are small, non-coding RNAs that bind to messenger RNA and regulate expression of genes involved in human cancers, including every subtype of thyroid cancer. ThyraMIR® measures the expression of 10 microRNAs. Both ThyGeNEXT® and ThyraMIR® are covered by both Medicare and Commercial insurers, with more than 280 million patients covered.
Interpace is a leader in enabling personalized medicine, offering specialized services along the therapeutic value chain from early diagnosis and prognostic planning to targeted therapeutic applications.
Interpace’s Diagnostic Business is a fully integrated commercial and bioinformatics business unit that 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 four commercialized molecular tests and one test in a clinical evaluation process (CEP): PancraGEN® for the diagnosis and prognosis of pancreatic cancer from pancreatic cysts; ThyGeNEXT® for the diagnosis of thyroid cancer from thyroid nodules utilizing a next generation sequencing assay; ThyraMIR® for the diagnosis of thyroid cancer from thyroid nodules utilizing a proprietary gene expression assay; and RespriDX® that differentiates lung cancer of primary vs. metastatic origin. In addition, BarreGEN® for Barrett’s Esophagus, is currently in a clinical evaluation program whereby we gather information from physicians using BarreGEN® to assist us in positioning the product for full launch, partnering and potentially supporting reimbursement with payers.
