Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved

Summary

This study looks at whether a special blood filter called oXiris helps people with septic shock and kidney failure survive. Researchers will review medical records of 360 adults in the ICU who needed continuous blood filtering. They will compare those who got the oXiris filter with those who got standard filters, focusing on survival and how quickly patients recover.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
oXiris hemofilter
What this could lead to
If it works, this could point toward a better way to filter blood in septic shock, potentially improving survival and reducing organ failure.
What could go wrong
This is a retrospective study, not a randomized trial, so results may be biased. The oXiris filter is already used, but its survival benefit remains unproven.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of adult patients (aged 19 or older) diagnosed with septic shock and acute kidney injury (AKI) who required continuous renal replacement therapy (CRRT). The treatment group includes approximately 120 patients who received the oXiris® hemofilter at five tertiary academic hospitals in South Korea between March 2021 and August 2025. The control group comprises approximately 240 patients who received standard CRRT filters, identified from the Korea Sepsis Alliance (KSA) registry, a nationwide multicenter sepsis cohort. All subjects are selected based on the availability of electronic medical records (EMR) and registry data that include critical clinical covariates for Target Trial Emulation.
