VolitionRx Demonstrates More Than 90% Accuracy for Colorectal Cancer NuQ(R) Blood Test in Completed Prospective Study

NAMUR, Belgium, Dec. 8, 2015 /PRNewswire/ -- VolitionRx Limited (NYSE MKT: VNRX) today announced results demonstrating that its NuQ® blood tests accurately detected 91% of colorectal cancer cases in a clinical study.

The study included 121 patients referred for colonoscopy at the university hospital, CHU Dinant Godinne - UCL Namur, in Belgium, who either presented with symptoms suggesting the presence of colorectal cancer or were high-risk subjects. Of these, 23 were found to have colorectal cancer. Investigators in the prospective study tested blood samples collected according to VolitionRx's standard procedures, taken from subjects prior to their colonoscopy, to determine whether a NuQ® test could accurately predict the subsequent findings of the colonoscopy.

Analysis of the results revealed that a panel test of four NuQ® biomarker assays, adjusted for age, detected 91% of colorectal cancer cases at 90% specificity. In addition the results showed equally accurate detection of early- and late-stage cancers. The analysis also revealed that the same panel test detected 67% of the type of polyps most likely to develop into cancer, demonstrating a potential for NuQ® tests to accurately detect the complete spectrum of cancer development from pre-cancerous polyps through early-stage to late-stage colorectal cancer.

Colorectal cancer is one of the most preventable cancers, yet there are still 50,000 deaths and more than 130,000 new cases diagnosed every year in the U.S. alone1. Colonoscopy examinations provide a high percentage of detection, yet due to their invasive and costly nature, more than one third of adults of screening age in the U.S. are not screened with such a procedure2. The five-year survival rate for colorectal cancer is 90% when detected at stage I but only 13% if detected at stage IV.

Professor Lionel D'Hondt, Head of the Department of Oncology at CHU Dinant Godinne - UCL Namur, remarked, "The development of better methods for the early detection of colorectal cancer is critical for the improvement of patients' survival rates. We have found that a NuQ® panel test detects colorectal cancer and pre-cancer, with high accuracy, indicating it may be useful as a routine clinical colorectal cancer blood test."

VolitionRx Chief Scientific Officer, Dr. Jake Micallef, Ph.D., added, "Current screening options for colorectal cancer are limited to invasive endoscopy procedures and fecal tests. Neither of these methods is patient-friendly and their uptake by the population at large is poor. In contrast, a NuQ® panel test uses a tiny amount of blood and could be added to a routine medical check-up along with cholesterol, blood sugar, liver function, and other commonly administered blood tests. The study results demonstrate detection of 91% of colorectal cancer cases using an age-adjusted panel of four NuQ® assays. Moreover, 87% of colorectal cancer cases and 67% of high-risk dysplastic pre-cancerous polyps were detected using an unadjusted panel of five NuQ® assays alone, and no patient information. The study data provide evidence of the significant potential of our diagnostic NuQ® tests for detecting colorectal cancer."

Cameron Reynolds, Chief Executive Officer of VolitionRx, commented, "To detect colorectal cancer and pre-cancerous polyps with such high accuracy in an affordable blood test is a notable development. VolitionRx has demonstrated detection rates of 90% or higher in pancreatic cancer, lung cancer and now colorectal cancer, showing our unique proprietary platform technology can accurately detect a variety of cancers. Even more encouraging is the accuracy in detecting early-stage cancers and pre-cancers; finding tumours before they spread is a truly crucial breakthrough that will improve the outcomes for cancer patients."

About VolitionRx

VolitionRx is a life sciences company focused on developing blood-based diagnostic tests for different types of cancer. The tests are based on the science of Nucleosomics which is the practice of identifying and measuring nucleosomes in the bloodstream – an indication that cancer is present.

VolitionRx's goal is to make the tests as common and simple to use, for both patients and doctors, as existing diabetic and cholesterol blood tests. VolitionRx's research and development activities are currently centred in Belgium as the company focuses on bringing its diagnostic products to market first in Europe, then in the U.S. and ultimately, worldwide.
