Blood filter aims to calm deadly inflammation in septic shock
NCT ID NCT07715110
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This pilot trial tests whether a special cartridge placed in a blood-filtering machine can improve outcomes for people with septic shock, a severe and often deadly infection response. The cartridge is designed to remove inflammatory molecules from the blood, which may reduce organ damage and help patients recover. The study includes two groups: those with standard septic shock and those with a more severe form called refractory septic shock. Researchers will compare a combination of survival and early improvements in inflammation, organ function, and blood pressure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A resin-based hemoadsorption cartridge inserted into a continuous renal replacement therapy circuit to filter inflammatory mediators from the blood.
- What this could lead to
- If successful, this approach could provide a new way to reduce inflammation and organ damage in septic shock, potentially lowering the high death rate.
- What could go wrong
- This is a very small pilot study with only 16 participants, so results may not apply broadly. The treatment is experimental and may not improve outcomes or could cause complications.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * All of the following: * Age ≥ 18 years. * Diagnosis of septic shock per Sepsis-3, with an identified or highly probable infectious focus. * Meeting the operational definition of one of the two severity strata (SS or RSS) detailed in 6.1. * Onset of septic shock within the last 24 hours (applied identically to both strata). * Large-bore vascular access. * Informed consent signed by the legal representative. Exclusion Criteria: * Decision to limit life-sustaining therapy made or anticipated within the next 48 hours. * Absolute contraindication to anticoagulation with heparin and citrate. * Predominant non-septic shock (hemorrhagic, primary cardiogenic, obstructive). * Ongoing pregnancy. * Platelet count \< 20,000/µL. * Significant pharmacological immunosuppression: chronic corticosteroids at doses \> 20 mg/day prednisone equivalent, biologics within the last 6 months, cytotoxic chemotherapy within the last 4 weeks. * Solid organ or hematopoietic stem cell transplantation. * Concurrent participation in another clinical trial.
