VolitionRx Announces CE Marks for Two NuQ Blood Assays for Detection of Colorectal Cancer

Reading time: 5 – 8 minutes

VolitionRx Limited (NYSE MKT: VNRX) recently announced CE marking for two blood-based diagnostic assays for the detection of colorectal cancer. The biomarker assays, NuQ®V001 and NuQ®T003, identify and analyze fragments of chromosomes, called nucleosomes, circulating within the blood for the presence of cancer signatures.

The two new CE marks follow the announcement last September of VolitionRx’s first CE mark, which was for the NuQ®X001S biomarker assay for detecting colorectal cancer. Each of the three biomarker assays now CE marked represent a different family of NuQ® assays that target different features of nucleosomes, which consist of short strands of DNA wrapped around a core of eight histone proteins. The NuQ®T family of biomarker assays target the whole nucleosome. The other family members, NuQ®X and NuQ®V, target epigenetic cancer signals within the nucleosome, which affect gene activity without altering the DNA sequence. These include modifications to the DNA (targeted by the NuQ®X family of biomarker assays) and variations to the histone proteins (targeted by the NuQ®V family).

VolitionRx plans to offer a commercial test for colorectal cancer consisting of a panel of 4-6 individual NuQ® biomarker assays that require only a single drop of blood from patients. The Company is currently conducting ongoing clinical trials and following the CE compliance process for further biomarker assays in order to refine the make-up of the panel and produce the highest accuracy detection rates. VolitionRx anticipates launching a CE marked panel test for the detection of colorectal cancer for clinical use in Europe toward the end of 2016.

The announcement of the two new CE marks also follows the recent release of data from a 430-subject trial, which demonstrated that VolitionRx’s NuQ® blood tests accurately detected 86% of early-stage colorectal cancers at 78% specificity, as well as 75% of high-risk colorectal adenomas, or pre-cancerous polyps that were most likely to become cancerous.

“We are delighted to announce CE marking for two new members of our family of NuQ® biomarker assays,” commented Gaetan Michel, PhD, Chief Executive Officer of Belgian Volition SA. “In recent months, VolitionRx has achieved consistently excellent results for colorectal cancer detection using a panel test of NuQ® assays and has successfully detected both early- and late-stage cancer, which is critical for improving five-year survival rates. Since we announced our first CE marked biomarker assay last September, the Company has continued its strategic work toward additional CE marking that will allow us to deliver first-class quality products to physicians and their patients. Through this strategy, we have widened the span of discovery for relevant biomarkers and moreover broadened the potential use of our products. The CE marks mean that these NuQ® products are compliant with EU legislation and meet EU in-vitro diagnostic medical device requirements for clinical use in the European market.”

“This CE marking is yet another very important milestone for the Company on our path to making our blood tests available to patients,” added Cameron Reynolds, President and Chief Executive Officer of VolitionRx. “We are now able to sell three biomarker assays clinically in the 28 member states of the European Union, as well as Switzerland, Turkey, Iceland, Norway and Liechtenstein — potentially reaching a population of nearly 600 million people including more than 150 million of screening age. We are currently in the process of CE marking other assays to finalise the panel for the anticipated European launch of our tests late this year. We are also progressing toward our goal of making our assays available for clinical use in the U.S. and the rest of the world. Due to the non-invasive, low-cost and patient friendly nature of NuQ® blood tests, we believe our technology has the potential to gain market acceptance and save lives in Europe, the U.S. and worldwide.”
