Peer Reviewed Clinical Study for Nu.Q® Biomarkers Published in Shock Journal

HENDERSON, Nev. , March 30, 2026 /PRNewswire/ -- VolitionRx Limited (NYSE AMERICAN: VNRX) ("Volition"), a multi-national epigenetics company, announces the publication of a new clinical manuscript demonstrating that nucleosome levels, as measured by Volition's Nu.Q®H3.1 and Nu.Q®H3R8 Citrulline are elevated in people that have experienced a traumatic event and are even higher in those patients that go on to have complications from the trauma.

Principal Investigator and Senior Author, Myung S. Park, Professor of Surgery, Associate Medical Director of Research, Trauma Center, Director, Clinical Research Trials Unit, Center for Clinical and Translational Science, Department of Surgery, Division of Trauma, Critical Care & General Surgery, Mayo Clinic, Rochester commented:

"The identification of reliable biomarkers in trauma patients is a clinical challenge and remains an unmet need in the emergency and surgical setting.

"In this study we analyzed 674 trauma patients and found that levels of the H3.1 and H3R8 Citrulline nucleosomes are elevated early after traumatic injury, especially in those who developed Venous Thromboembolism ("VTE").

"These findings underscore the importance of understanding the pathophysiology of nucleosomes in inducing VTE and their role as biomarkers.  These biomarkers could aid in early risk identification and may inform targeted preventive strategies in trauma care.

"We have continued to work with the Volition team and look forward to publishing further findings."

Dr Andrew Retter, Medical Consultant, Volition commented:

"This is significant, not only for clinicians, patients and their families, but also for Volition: a peer reviewed publication with the Mayo Clinic research team strongly supports our efforts to commercialize our Nu.Q® NETs product.

"This study, together with previously published evidence^1-4 , demonstrates that Nu.Q® NETs may enable clinicians and researchers to anticipate disease, guide treatment decisions, and monitor patients over time, across acute and chronic conditions."
