Study Demonstrates Superior Performance of ThyGeNEXT® and ThyraMIR® vs. Other Molecular Tests
PARSIPPANY, NJ, Oct. 26, 2020 (GLOBE NEWSWIRE) — Interpace Biosciences, Inc. (NASDAQ: IDXG) announced today that the study entitled “Multiplatform molecular test performance in indeterminate thyroid nodules” was published on-line in the peer-reviewed journal, Diagnostic Cytopathology. This paper represents the culmination of a multi-center, blinded clinical validation study in which gold standard unanimous histopathology consensus diagnosis was utilized. The study results demonstrate that ThyGeNEXT® + ThyraMIR® combination testing yield the highest positive predictive value (PPV) and similar negative predictive value (NPV) in comparison to other marketed tests for the same indication.
Approximately 25% of thyroid nodule fine needle aspirates (FNAs) have cytology that is indeterminate for malignant disease. Ancillary multiplatform testing with ThyGeNEXT® and ThyraMIR® assists in the accurate risk stratification of these FNAs, ultimately helping to distinguish patients who are more likely to benefit from conservative management from those who are more likely to benefit from surgical intervention.
The published manuscript is the first to report the performance characteristics of combination ThyGeNEXT® and ThyraMIR® testing in a blinded multicenter study. ThyGeNEXT® is the company’s most recent next generation sequencing based test that was expanded from its original version (ThyGenX®) to include markers that have targeted therapies and those that can identify aggressive forms of thyroid cancer. The study demonstrates that combination testing with ThyGeNEXT® and ThyraMIR® has both high sensitivity (95%) and high specificity (90%) for identifying disease. It also highlights the important role that ThyraMIR®—the company’s proprietary microRNA risk classifier—can play in helping to identify malignancy in nodules where single platform mutation panels commonly detect mutations that by themselves have suboptimal PPV for malignancy.
According to Jack Stover, President and CEO of Interpace, “The results of this independent study reported in a well-respected journal reflect the strong clinical performance and overall value of our combined thyroid assays in helping physicians manage their patients with potential thyroid cancer.”
About ThyGeNEXT® and ThyraMIR®
ThyGeNEXT® is Interpace’s most recent next generation sequencing test that was expanded from its original version (ThyGenX®) to include markers that have targeted therapies and those that can identify aggressive forms of thyroid 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, as well as Medullary Thyroid Carcinoma. 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 Medicare and most Commercial insurers.
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.
