European Registry for Hemadsorption in Sepsis With the Seraph Filter
An observational study of Sepsis and Acute Respiratory Distress Syndrome, run by Croatian Society for Organ Support at 1 site in Croatia.
Trial summary
Although new techniques like extracorporeal blood purification have lately emerged, septic patients still have very high hospital mortality rates. Sepsis can be induced by either viremia, bacteriemia or in some cases both. Read more about this study

- laboratory and clinical evidence of systemic inflammation: high levels of inflammatory cytokines such as IL-6 (>25 pg / ml); high values of inflammatory parameters from serum (leukocytes >15x10 9 / l, CRP >40 mg / l, procalcitonin >0.9 mg / l) and a high SOFA score (>2).
- clinical symptoms of hemodynamic instability requiring vasopressors
- diagnosis of ARDS

About this study
Official title: European Registry for Hemadsorption of Septic Patients With the Seraph 100 Microbind Affinity Blood Filter (ASTREA Study)
Although new techniques like extracorporeal blood purification have lately emerged, septic patients still have very high hospital mortality rates. Sepsis can be induced by either viremia, bacteriemia or in some cases both. Many studies have reported the effectiveness of different hemadsorbers, but patient sample sizes have been inadequate for definitive conclusions. Secondly, there are still no clear inclusion criteria as well as criteria for when to cease hemadsorption mostly due to immune dysregulation or cascade coagulation disorders. The aim of this observational prospective registry is to evaluate the effectiveness of the Seraph® 100 Microbind® Affinity Blood Filter (Seraph 100) in the treatment of septic ICU patients and to evaluate which cluster of these patients should benefit most with this therapy.
Read the detailed description
Hemadsorption was introduced in everyday clinical practice before the COVID-19 pandemic. The efficacy of hemadsorption removal of endotoxins and cytokines is still, by some, controversial due to the fact that most of the studies were performed in a small number of patients with very different diagnoses, comorbidities and disease severity. Furthemore, some studies enrolled patients over a prolonged period of time with very high SOFA scores and multi-organ failure where it is difficult to expect any significant effect of any kind of organ support therapy. The COSA registry reported that the treatment of COVID-19 patients with Seraph 100 was well tolerated and observed lower mortality in the registry when compared to calculated mortality.
The primary aim of this observational prospective, multi-center, multistate web-based registry is to define the effectiveness and outcome of Seraph 100 treatment(s), investigate possible advantages of early targeted treatment and to set indications/inclusion criteria for the treatment of ICU septic patients with the method of hemoadsorption.

Questions about this trial
What is this clinical trial studying?
An observational study of Sepsis and Acute Respiratory Distress Syndrome, run by Croatian Society for Organ Support at 1 site in Croatia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 8 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Croatia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Vedran Premuzic, M.D., Ph.D. (+385915274778, vpremuzic@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Survival (time frame: 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Nov 2022; AzTrials last refreshed its copy on 7 Nov 2026.
