Study summary

Hemoadsorpion in Patients With Septic Shock: Efficacy and Safety Evaluation. A Pilot Multicenter Randomized Controlled Trial.

The goal of this clinical trial is the estimation of the efficacy and safety of hemoadsorption procedures (LPS (Lipopolysaccharide) and inflammatory mediators adsorption) in participants with septic shock.

The main questions it aims to answer are:

Does hemoadsorption decrease the severity of MODS (multiple organ disfunction syndrome)?

The study will include participants aged 18 to 80 years with a verified diagnosis of septic shock according to SEPSIS 3 criteria, diagnosed within 12 hours, and a SOFA (sequential organ failure assessment) score of 9 or more.

In addition to Standard of Care (SOC), blood purification, including hemoadsorption, will be used. The minimum waiting time after diagnosis of septic shock and initiation of basic therapy before inclusion of the patient in the study therapy is 4 hours.

The choice of procedure will be based on the EAA (Endotoxin Activity Assay) result:

  • for an EAA level of 0.6-0.9, selective lipopolysaccharide (LPS) adsorption with duration from 2 to 10 hours;
  • for an EAA level less than 0.6, inflammatory mediator adsorption with duration from 6 to 12 hours.

The choice of a specific adsorbers within the LPS and inflammatory mediator adsorption group will be based on randomization.

The use of LPS adsorption is planned based on randomization: Toramyxin R-20 or Efferon LPS. The use of inflammatory mediator adsorption is planned based on randomization: Jafron (HA 330) or CytoSorb.

Read the detailed description

Every participant will receive 2 adsorption procedures. The second procedure will be initiated no later than 24 hours after the initiation of the first procedure.

LPS adsorption will be performed in 38 participants (Efferon LPS in 19 participants and Toramyxin in 19 participants), two procedures per participant.

Inflammatory mediator adsorption will be performed in 38 participants (Jafron HA 330 in 19 participants and CytoSorb in 19 participants), two procedures per participant.

Sample size calculations were performed separately for each treatment cohort. For the endotoxemia cohort (EAA level of 0.6-0.9), this randomized trial is designed to compare Efferron LPS and Toraymyxin with respect to change in SOFA score at 72 hours.

At present, no universally accepted minimal clinically important difference (MCID) has been established for the SOFA score in participants with septic shock. Therefore, the assumed treatment effect was derived from published evidence and expert clinical judgment.

In the EUPHAS trial, polymyxin B hemoperfusion was associated with a mean reduction in SOFA score of approximately 3.4 points at 72 hours, whereas minimal change was observed in the control group. Similarly, the LASSO study demonstrated substantial improvement in organ dysfunction following endotoxin adsorption therapy.

For the inflammatory mediator adsorption cohort (EAA level less than 0.6), this randomized trial is designed to compare CytoSorb and Jafron HA 330 with respect to change in SOFA score at 72 hours.

In the retrospective study Mehta et al., CytoSorb hemoperfusion was associated with a mean reduction in SOFA score of approximately 2.0 points after treatment in survival group. Similarly, the case series Onuk et al. demonstrated substantial improvement in organ dysfunction following inflammatory adsorption therapy with Jafron HA 330 with a mean reduction in SOFA score of approximately 3.5 points at 72 hours.

A between-group difference of 2.5 SOFA points was considered clinically meaningful for both Endotoxin hemoadsorption and inflammatory mediators hemoadsorption because it represents a substantial proportion of the treatment effect observed in previous hemoperfusion studies and corresponds to a clinically relevant difference in the degree of organ dysfunction improvement.

The sample size for both groups (LPS and inflammatory mediator adsorption) was calculated based on the following assumption: the primary endpoint was the change in SOFA score at 72 hours (ΔSOFA); the expected between-group difference - 2.5 points on the SOFA score; standard deviation of ΔSOFA - 2.5 points; equal allocation ratio (1:1); two-sided significance level (α) of 0.05; statistical power of 80%.

Sample size estimation was performed in R using the power.t.test() function. The calculation yielded a required sample size of 16.7 participants per group. Therefore, a minimum of 17 participants per group (34 participants in total) is required to achieve the planned statistical power.

To account for an anticipated 10% dropout rate, the final sample size will be 19 patients per group (38 participants in total for LPS+ 38 participants in total for Inflammatory mediators adsorption. 76 participants in total).

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Start is estimated for Jun 2026; primary completion for Jun 2027, 12 months later.

Of 164 non-industry interventional studies with no phase under Shock, Septic, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 41. This study's planned 12 months is below that.

Counting every sponsor, half of 172 studies reached it within 25 months; a quarter within 12 and three quarters within 42.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 2, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
