On October 5, 2025, progress in clinical diagnostics took a promising step forward with the announcement of a new study focusing on nucleosome monitoring as an outcome predictor for critically ill patients. Sponsored by Erasme University Hospital and listed as not yet recruiting, this study explores how nucleosome levels—DNA fragments found in the blood—could influence care decisions for conditions such as sepsis, septic shock, cardiac arrest, pancreatitis, acute brain injury, trauma, and cardiogenic shock.
Critical care teams, clinical researchers, regulatory professionals, and device developers may find the study’s implications vital to shaping future diagnostic tools and methodologies. Below, we delve into the details of the study, its potential impact, and answers to related questions.
What changed?
Erasme University Hospital announced a significant focus on nucleosome monitoring via an upcoming clinical trial listed on ClinicalTrials.gov. While the trial is not yet recruiting, the study aims to evaluate whether nucleosome levels act as reliable biomarkers for predicting outcomes in critically ill patients across multiple conditions.
Conditions specified include sepsis, septic shock, cardiac arrest, pancreatitis, acute brain injuries, blunt trauma, and cardiogenic shock—areas of critical care demanding improved diagnostic precision.
Study details
Why nucleosome monitoring?
Nucleosomes are basic units of chromatin structure, composed of DNA wrapped around histone proteins. Elevated nucleosome levels may signal cell death or systemic inflammation, often encountered in critically ill patients. These measurements could guide therapeutic interventions by shedding light on disease progression and recovery potential.
The focus aligns with broader efforts to integrate biomarker-based diagnostics into critical care settings, addressing unmet needs in real-time disease monitoring and clinical decision-making.
Scope of the study
Under Erasme University Hospital’s sponsorship, the trial spans multiple severe conditions. Researchers aim to systematically measure circulating nucleosome levels and correlate them against patient outcomes. While recruitment has not begun, healthcare stakeholders should watch for developments in study methodology and data collection protocols.

Clinical implications
Who could benefit?
The study is particularly relevant to healthcare providers managing complex cases, such as septic shock or cardiac arrest, where predictive tools are limited. Regulators may also find insights valuable for assessing safety and performance parameters of future diagnostics.
Diagnostic device innovation
If nucleosome monitoring proves effective, device manufacturers could leverage these findings to engineer diagnostic platforms, addressing both regulatory standards and clinical needs. Such tools may integrate seamlessly into hospital workflows for rapid, real-time monitoring.
FAQs
1. What conditions does the study address?
The study targets sepsis, septic shock, cardiac arrest, pancreatitis, acute brain injuries, trauma (blunt), and cardiogenic shock.
2. Has recruitment started for this study?
No, recruitment is currently listed as “not yet recruiting” on ClinicalTrials.gov.
3. Why are nucleosomes significant in critical care?
Nucleosomes may serve as biomarkers for cell death and systemic inflammation, offering a diagnostic tool for predicting patient outcomes.
4. Can this study impact medical device development?
Yes, findings could inspire new diagnostic devices tailored to real-time nucleosome monitoring, meeting MDR safety and performance criteria.
Conclusion
Nucleosome monitoring holds promise as a predictive tool for critically ill patients across diverse conditions. While the study is still in the planning phase, its implications for patient care, regulatory policy, and device innovation are far-reaching. Clinicians, quality teams, and regulatory experts should stay informed about trial progress.
