VolitionRx Limited has announced preliminary data from a pilot study demonstrating that the Company's NuQ® blood test detected 86% of subjects with a deadly lung disease, called Idiopathic Pulmonary Fibrosis (IPF). This is the first set of results from a non-cancer trial of VolitionRx's NuQ® blood tests, which demonstrates the technology's potential as a diagnostic for other diseases.
The clinical study was conducted with Liège University Hospital in Liège, Belgium. Of the 78 subjects, 21 were non-treated patients with IPF, 27 patients had been treated for IPF, and 30 were healthy volunteers. Analysis of the preliminary data revealed that a single NuQ® biomarker assay detected 86% of the non-treated IPF patients (18 of 21) from the healthy subjects with only 6 false positives (80% specificity).
IPF is a chronic, progressive and lethal lung disease characterised by scarring and reduction in the lungs' capacity to absorb oxygen. In the United States, around 100,000 people are currently affected by IPF, with approximately 30-40,000 new cases diagnosed each year1. The true incidence rate is likely higher given current difficulties in proper diagnosis, classification and reporting.
Diagnosis of IPF is based on a range of clinical, laboratory, radiological and pathological tests, often to exclude other conditions first. The key diagnostic test currently available is High Resolution Computed Tomography (HRCT), a costly procedure to which access is limited in many countries. Current treatments include pulmonary rehabilitation, oxygen therapy, medication, and, in a small number of cases, lung transplants. The disease has a poor prognosis, with many patients surviving only 3-5 years after diagnosis1.
VolitionRx's Chief Scientific Officer, Dr. Jake Micallef, said, "Some NuQ® biomarker assays are particularly appropriate for the detection of inflammatory diseases such as IPF. To have achieved such impressive accuracy for detecting IPF using only a single such NuQ® biomarker assay in this pilot study is very encouraging. Our next step will be to work on a larger study sample and to include additional NuQ® biomarker assays to form a panel blood test that could have even greater accuracy."
Dr. Julien Guiot, project coordinator from Liège University Hospital, said, "At present, relatively little is known about this deadly disease. An accurate, cost-effective diagnostic for IPF could have a significant impact in assisting researchers in their efforts to understand the disease and develop a more viable treatment and potential cure."
Cameron Reynolds, Chief Executive Officer of VolitionRx, commented, "Our recent results show that panels of NuQ® biomarker assays can detect colorectal, lung and pancreatic cancers with more than 90% accuracy. The excitement generated by the success of these cancer-related clinical trials has led to interest from clinical partners to investigate the effectiveness of NuQ® blood tests in detecting other diseases, starting with IPF. We believe that the success of this pilot study for IPF demonstrates the potential of our Nucleosomics® technology as a diagnostic platform for a broad range of diseases and establishes a lucrative potential new market for VolitionRx. Moreover, we are excited that our non-invasive blood tests may assist in creating better outcomes for patients with this deadly disease."
