Blood filter could shield vessels in septic shock
NCT ID NCT07711197
First seen Jul 17, 2026 · Last updated Jul 17, 2026
Summary
This trial investigates whether a blood-filtering device called CytoSorb can reduce damage to blood vessels in people with septic shock, a life-threatening condition. The device removes inflammatory molecules from the blood. Researchers will measure changes in a marker of vessel injury and track organ function in 110 participants.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CytoSorb hemoadsorption device used to filter blood and remove inflammatory molecules
- What this could lead to
- If successful, this approach could offer a new way to stabilize blood vessels and reduce organ failure in septic shock, potentially saving lives.
- What could go wrong
- This is a relatively small, early-stage trial, and the treatment may not improve outcomes or could cause complications like bleeding or clotting.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Septic shock as defined by Sepsis-3 criteria. * Serum lactate levels \>2 and \<8 mmol/L at screening. * Fluid unresponsiveness: Objectively confirmed via dynamic tests or fluid challenges following initial resuscitation. * Vasopressor Dose Threshold: Norepinephrine base equivalent (NEE) dose \> 0.5 µg/kg/min. * Systemic corticosteroid treatment on board for at least 30 minutes. * Tissue perfusion impairment: Persistently elevated serum lactate AND/OR prolonged capillary refill time (\> 3 seconds) despite standard therapy. * Alternative causes of shock (e.g., obstructive or cardiogenic) must be ruled out using critical care ultrasonography (CCUS). * Arterial, central venous catheters and an invasive hemodynamic device (PiCCO, Getinge) in place. * Inclusion within a maximum of 12 hours after the onset of vasopressor need. * High likelihood of a dysregulated immune response (PCT ≥ 5 ng/mL AND/OR IL-6 ≥ 1000 pg/mL AND/OR Ferritin ≥ 1000 ng/mL). * Written informed, retrospective or prospective consent. Exclusion Criteria: * Patients under 18 years of age and over 80. * Unlikely to survive for 24 hours (Moribund). * Pregnancy. * SOFA-2 score ≥ 16 at ICU admission. * Source control is uncertain. * Thrombocytopenia (\<20,000/µL). * Criteria of standard guideline-based medical treatment not exhausted. * End-stage organ failure (chronic renal failure (estimated glomerular filtration rate (eGFR) \<15 mL/min/1.73 m2), chronic liver failure (MELD Score \>30, ChildPugh score class C.), chronic heart failure (New York Heart Association class IV.); severe chronic pulmonary disease (chronic obstructive pulmonary disease: GOLD D)). * Expected need to disconnect CytoSorb therapy for more than 2 hours (e.g., surgery, CT transfer).
