VolitionRx Limited Announces Inclusion of its Nu.Q® NETs Assay as Innovative Biomarker in France's Real-World Evaluation of Early Detection of Sepsis

HENDERSON, Nev., Dec. 4, 2025 /PRNewswire/ -- VolitionRx Limited (NYSE AMERICAN: VNRX) ("Volition"), a multi-national epigenetics company, today announces the inclusion of its Nu.Q® NETs H3.1 assay in "DETECSEPS", a real-world evaluation of early detection of sepsis. DETECSEPS Consortium was awarded winner of the "Challenge Prevention" call for proposals launched by the French Health Innovation Agency and operated by the Banque Publique d'Investissement, as part of the France 2030 plan, during the official ceremony held yesterday,  December 3, in Paris, France.  This consortium will be financed with approximately €6.3 million (~$7.3 million) by the French government and is a key national strategic axis. As industry partners, Volition (XASE:VNRX) will provide the sole biomarker and Euroimmun, part of Revvity, will provide the  Immunodiagnostic Systems (IDS) i10® automated analyzer.

Professor Sébastien Beaune, Emergency Department, IHU SEPSIS, Ambroise Paré Hospital (AP-HP)  and Coordinating Investigator of DECTECSEPS program commented:

"DETECSEPS aims to significantly contribute to reducing the socio-economic burden of sepsis by proposing a radical change in the emergency care pathway for patients with an infection and at risk of progressing to sepsis.

"Sepsis carries a heavy social, economic and health burden worldwide; there are approximately 166 million cases worldwide resulting in 21.4 million deaths in 2021¹. Moreover, even survivors of sepsis go on to have significant health problems with 33% mortality within one year, 40% of survivors being re-admitted to hospital within 90 days of discharge and one sixth of survivors experiencing significant morbidity such as functional limitations.

"Early detection of sepsis in people with an infection and at risk of deteriorating is likely to have favorable public health impact."

Professor Djillali Annane, Intensive Care Department, IHU SEPSIS, Raymond Poincaré Hospital (AP-HP) and Scientific Director of DETECSEPS commented:

"DETECSEPS aims to implement in real life an original early screening strategy based on the combination of a clinical score (NEWS2) and Volition's Nu.Q® H3.1 biomarker as the sole biomarker, whose diagnostic performance is well established.

"Results show that H3.1 accurately distinguishes sepsis from non-infectious systemic inflammation, is highly correlated with disease severity, and provides excellent prognostic utility for outcomes such as organ failure and mortality². The prognostic power of H3.1 measured at ICU admission significantly exceeded existing severity scores such as APACHE II and SOFA scores³.

"We believe that combining the two diagnostic tests (NEWS2 and Nu.Q® H3.1) could improve test performance and make a huge difference in terms of early detection in an emergency setting.

"Our aim is to have a positive impact on the care pathway, including early discharge to home (progression to sepsis unlikely or very unlikely), hospitalization in ICU or non-ICU ward, and initiation of the "3-hour bundle" measures recommended by the Surviving Sepsis Campaign (progression to sepsis likely or very likely)."

Dr Andrew Retter, Chief Medical Officer, Volition, added:

"H3.1 levels can be routinely measured using the Immunodiagnostic Systems (IDS) i10® automated analyzer, provided by Euroimmun, with results available within one hour. The addition of the value of our biomarker could potentially enhance the application and reliability of NEWS 2 to triage the sickest patients. I believe that this is both a huge and realistic expectation.

"DETECSEPS aligns with Volition's core purpose of operationalizing our understanding of epigenetics and in particular, of H3.1 in clinical practice, to help identify and monitor the severity of disease. The DETECSEPS program provides an opportunity to receive individualized or personalized care, adjusted to the risk of deterioration and progression to sepsis."

Mr. Remi Rabeuf, VP Corporate Alliances and Strategic Partnership, Volition concluded:

"We are proud to be, alongside Euroimmun, industry members of this Consortium and are delighted that the program has been approved and financed by the French government.

"We hope that through the earlier identification of sepsis lives can be saved, the quality of life of survivors can be improved and importantly that the burden on healthcare systems can be reduced.

"As Professor Beaune said, sepsis carries a heavy social, economic and health burden worldwide; we believe this program could be rolled out not only nationally in France, but also in many other countries around the world. With approximately 166 million cases annually the opportunity for testing represents a multi-billion dollar Total Addressable Market."

About the Consortium

The Hospital-University Institute (IHU 3) SEPSIS (ex-PROMETHEUS) has been accredited under the France 2030 program. Led by Université Paris-Saclay, CEA, AP-HP, Inserm, and their academic, non-profit, and industrial partners, this world-class comprehensive center integrating research, training, and healthcare aims to halve, within ten years, the mortality and long-term complications caused by sepsis.

The institute's interdisciplinary approach places it in a unique position to break down barriers in sepsis research and thereby develop new diagnostic tests and therapeutics. The IHU brings together 60 research teams comprising 275 researchers, as well as several hospitals from AP-HP and the Hospices Civils de Lyon, representing 94 clinician-researchers. Over the past five years, the IHU's scientific community has produced more than 6,800 scientific publications and filed 115 patents.

In the DETECSEPS project, the two hospital partners of the IHU, AP-HP and HCL, are joining forces with two leading industrial partners (IDS France and Volition) to advance sepsis prevention.
