HENDERSON, Nev, Nov. 17, 2023 /PRNewswire/ -- VolitionRx Limited (NYSE AMERICAN: VNRX) ("Volition"), a multi-national epigenetics company, is presenting at the 5th Annual Congress of Liquid Biopsy being held in Madrid, Spain. Lea Payen-Gay, Professor in Toxicology and Biochemistry, University of Lyon I Hospices Civils de Lyon, France and Dr. Jake Micallef, Chief Scientific Officer, Volition will present a one-hour session entitled "An Introduction to circulating nucleoproteins" on Monday November 20, 2023. Dr. Jake Micallef, Chief Scientific Officer at Volition, said: "We recently unveiled what we believe to be an entirely new cancer detection method1. This data has generated significant interest from large diagnostic and liquid biopsy companies alike. We are delighted to be presenting at the International Liquid Biopsy Society's Congress and furthering these discussions." In early-stage cancer, it is difficult to detect cancer-derived circulating tumor DNA (ctDNA) in the blood because it may comprise as little as 0.01% of the DNA present among a background of 99.99% normal DNA. Moreover, most of the cancer DNA has exactly the same sequence as normal DNA. As physical separation of tumor-derived and healthy circulating DNA has never before been achieved, current ctDNA detection methods involve DNA extraction, sequencing of all (cancer and normal) circulating DNA then analysis of the sequencing data using sophisticated computer bioinformatics, to tell them apart. Volition has developed a novel method for liquid biopsy involving the first reported physical isolation of a class of tumor-derived ctDNA fragments from blood. Cancer-derived ctDNA fragments are then extracted after removal of all normal background DNA of the same sequence for detection with a simple, low cost PCR test. Volition's proof of concept data1, demonstrates the isolation of tumor-derived ctDNA fragments from plasma. Volition tested the new method in a first small clinical experiment and detected a range of liquid and other cancers, including at early stage I disease. For example, 74% of leukemias were detected at 96% specificity and 77% of colorectal cancers were detected at 92% specificity with 2-qPCR assays. Notes: 1.

Cancer derived ctDNA fragments are then extracted after removal of all normal background DNA of the same sequence for detection with a simple, low cost PCR test. Dr. Jake Micallef, Chief Scientific Officer at Volition, explains: "Based on our 13 years of work on the chemistry of circulating chromatin fragments, we have developed a transformational wet chemistry pathway that identifies and physically isolates chromatin fragments that we know are tumor-derived from background DNA of the same sequence, using Chromatin Immunoprecipitation (ChIP), followed by quantitative real-time PCR (qPCR) testing to establish whether cancer is present. Removal of normal DNA obviates expensive and time-consuming DNA sequencing and bioinformatics allowing for rapid, cost-effective detection in a routine blood test." Volition's proof of concept data, presented at ESMO 2023, demonstrates the isolation of tumor derived ctDNA fragments from plasma. Volition tested the new method in a first small clinical experiment and detected a range of liquid and other cancers, including at early stage I disease. For example, 74% of leukemias were detected at 96% specificity and 77% of colorectal cancers were detected at 92% specificity with 2-qPCR assays. Dr. Micallef added: "These early assays were developed using a leukemia model, but surprisingly also detected many other cancers including detecting colorectal cancer in a blood test with an accuracy approaching that of current Fecal Immunochemical Tests (FIT). The results to date are exciting and may pave the way for a whole new class of undiscovered biomarkers, with hundreds or thousands of possible targets. We are now developing a range of cancer-specific assays which we expect to be more accurate and look forward to sharing our progress beginning in Q1 2024." Dr Michael Hubank, Professor of Translational Genomics at the Institute of Cancer Research, and Scientific Director of Clinical Genomics at The Royal Marsden NHS Foundation Trust, said: "The novel CTCF-ChIP/qPCR method developed by Volition shows great promise for the accurate, rapid, low-cost detection of cancer. The test complements existing approaches and has the potential to reach the high levels of sensitivity and specificity required to detect early-stage disease. It may also be suitable for automation, enabling application in hospital laboratories. We look forward to working with Volition on further research and development in this important and exciting area." Volition has organized a data insights webinar on Thursday 26th October at 10.30 AM U.S. Eastern to provide more information about the new cancer detection method. Click HERE to register.
