VolitionRx Limited (NYSE MKT: VNRX) today announced interim data demonstrating its NuQ® blood tests have accurately detected more than 90% of lung cancer cases in a study of 73 patients.
The clinical study is part of an ongoing larger prospective study of 240 subjects conducted with the Liege University Hospital (Belgium). The results were the outcome of an interim analysis of the first subjects recruited, including 29 subjects diagnosed with Non-Small Cell Lung Cancer, 22 diagnosed with another pulmonary disease (COPD) and 22 with healthy lungs.
The analysis revealed that, when combined with details of smoking history, a panel of four NuQ® biomarker assays detected 93% of lung cancer cases (27 of 29), with 91% specificity (2 false positive results among 22 healthy subjects).
Lung cancer is the second most common cancer in men and women, with around 220,000 new cases diagnosed each year and 158,000 deaths in the U.S. alone1. Lung cancer is the leading cause of cancer-related death in the U.S.2. Smoking history is the most important of the known and proven risk factors for lung cancer. While there are several types of lung cancer, Non-Small Cell Lung Cancer represents about 80% of those detected3. Typically, symptoms of lung cancer do not appear until the disease is already in an advanced stage, and they can be confused with others conditions. VolitionRx believes that there remains a high, unmet medical need for non-invasive and easy-to-use tests that detect early-stage cancer.
Professor Renaud Louis, Head of the Pneumology Department at Liege University Hospital (Belgium), said, "These data show that Lung Cancer is detected by a NuQ® blood test and confirm the findings of our previous pilot study, which we presented at BioWin Day in November 2014. We look forward to the results of the completed study."
VolitionRx Chief Scientific Officer, Dr. Jake Micallef, Ph.D., remarked, "The NuQ® blood test not only differentiates lung cancer from healthy subjects but also from the common lung disease, COPD, which is related to tobacco consumption. The best current test for lung cancer is a scan that has high accuracy but does not distinguish well between cancerous and non-cancerous fibrous nodules in the lung, leading to a high false positive rate2. Our interim data are exciting because they show both high sensitivity and very few false positives, indicating that a simple NuQ® blood test, used alone or in conjunction with current standards, may detect lung cancer and distinguish it from other lung diseases."
Cameron Reynolds, Chief Executive Officer of VolitionRx, added, "To be detecting more than 90% of cancers in this blinded trial is extremely exciting. VolitionRx's studies in colorectal cancer, pancreatic cancer and now lung cancer have consistently shown that our Nucleosomics® technology accurately detects cancers and is able to correctly distinguish among different diseases with a simple blood test. Using only a drop of blood, our NuQ® tests aim to be affordable, patient friendly, and to be as easy to use as they are simple to perform on existing hospital laboratory instruments."
VolitionRx expects to make full results of this ongoing lung cancer study available in 2016, as well as the results of another 600-subject lung cancer study conducted with the University Hospital Bonn in Germany.
