Scientists seek to unravel hidden subtypes of Sepsis-Linked lung failure
NCT ID NCT07281911
First seen Jun 26, 2026 · Last updated Aug 28, 2026 · Updated 2 times
Summary
This study will closely monitor 180 adults with sepsis-related acute respiratory distress syndrome (ARDS) who are on breathing machines. Researchers will take fluid samples from the lungs and blood at several time points to measure inflammation and injury markers. The goal is to identify distinct biological and physical patterns of the disease, which could eventually help doctors tailor treatments to each patient's specific condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could identify distinct subtypes of sepsis-related ARDS, paving the way for more personalized treatments in the future.
- What could go wrong
- This is an early observational study, not a treatment trial. It will not directly test any therapy, and the findings may not lead to immediate clinical changes.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Participants are adult ICU patients admitted with sepsis or septic shock who require invasive mechanical ventilation within 72 hours of sepsis diagnosis. These patients represent a high-risk population for sepsis-associated lung injury and ARDS, with dynamic biological and physiological changes occurring during the earliest phase of critical illness. The study follows participants for the first 96 hours after sepsis diagnosis to capture these early trajectories.
