Volition Announces MARS Consortium Clinical Study Suggests Nu.Q® H3.1. Concentrations are Closely Associated with Sepsis and Organ Failure

Peer Reviewed Clinical Study for H3.1 Biomarker Published in Critical Care

HENDERSON, Nev., June 12, 2025 /PRNewswire/ -- VolitionRx Limited (NYSE AMERICAN: VNRX) ("Volition"), a multi-national epigenetics company, today announced the publication of a new clinical manuscript suggesting that the Nu.Q^® H3.1 biomarker has the potential to inform clinical care in critically-ill Intensive Care Unit (ICU) patients in the assessment of sepsis, organ failure and subphenotypes.

Dr. Andrew Retter, Chief Medical Officer, Volition said:

"This independent peer-reviewed and published study (1713 patients) clearly demonstrates that Nu.Q^® H3.1 is a clinically meaningful, biologically specific marker of NETosis, with actionable potential in defined patient subgroups."

"H3.1 nucleosomes reflect the biological process 'NETosis,' supporting the emerging paradigm of "treatable traits" and biologically-informed risk stratification of patients."

"This evidence positions the assay not as a traditional rule-in/rule-out diagnostic, but as a dynamic tool for prognostic enrichment, therapeutic targeting, and clinical monitoring."

Lieuwe D.J. Bos, PhD, ICU Research, Principle Investigator at the Amsterdam University Medical Center, Amsterdam and Senior Author of the paper added:

"In this large observational study, we demonstrated that plasma nucleosomes, represented by H3.1 nucleosome concentration, are associated with the presence of sepsis, the severity of organ dysfunction, and a hyperinflammatory host response."

"Patients with acute kidney injury (AKI), disseminated intravascular coagulation (DIC), and acute respiratory distress syndrome (ARDS) exhibit significantly higher Nu.Q^® H3.1 levels compared to those without these conditions."

"The implications of our results are that NETosis, and H3.1 nucleosomes in particular, play at the intersection of infection, organ failure and inflammation and is not simply a surrogate marker of these conditions."

"This in turn opens up the opportunity of how excessive NETosis can be treated in patients with evidence of a high NETosis phenotype as measured by Nu.Q^®H3.1."

Gael Forterre, Chief Commercial Officer, Volition commented:

"This is significant, not only for clinicians, patients and their families, but also for Volition: a peer reviewed publication of a large independent clinical study strongly supports our efforts to commercialize our Nu.Q^® NETs product in this multi-billion dollar market."

About the Study
This study aimed to evaluate H3.1 nucleosomes in critical illness, assessing their relationship with sepsis, organ failure, inflammatory subphenotypes and outcomes.

The MARS cohort was used, comprising of consecutive Intensive Care Unit patients (n=1713 patients), with plasma samples collected on days 0, 2 and 4 (n=3671 plasma samples).

H3.1 nucleosome concentrations were measured using the Nu.Q^® NETs Immunoassay at baseline and longitudinally.

The relationship between H3.1 nucleosome concentrations and clinical outcomes was investigated.
