Hemoadsorption With CytoSorb® in Post-Cardiac Arrest Syndrome (CATCH)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT03523039

Brief Summary:
This prospective single-centre randomized control trial aims at evaluating the safety and efficacy of hemoadsorption with CytoSorb® in 40 patients with Post-Cardiac Arrest Syndrome admitted to the ICU.

Condition or disease Intervention/treatment Phase
Cardiac Arrest Device: CytoSorb® Hemoadsorption Not Applicable

Detailed Description:

Patients presenting Post-Cardiac Arrest Syndrome (PCAS) in the 24 hours following their admission in Intensive Care Unit will be randomly assigned either to a control group (standard of care) either to a "Hemoadsorption" group. In the latter, the patient will be connected in the 6 hours following randomization to an extracorporeal circuit, in which a Cytosorb ® cartridge will be placed. The circuit will be set up in hemoperfusion mode. The therapy will take place for a minimum of 12 hours and a maximum of 24 hours. Anticoagulation will be achieved using a regional heparin-protamin regimen.

Blood samples will be collected at randomization, T1 (6 hours post-randomization), T2 (12 hours after randomization), T3 (24 hours after randomization), T4 (48 hours after randomization) and T5 (48 hours after randomization), to assess change in inflammatory cytokine levels.

Arm Intervention/treatment
Experimental: Hemoadsorption
Hemoadsorption is performed using a CytoSorb® cartridge.
Device: CytoSorb® Hemoadsorption
The therapy is initiated within 6 hours from randomization and maintained for a minimum of 12 consecutive hours to a maximum of 24 consecutive hours.

No Intervention: Control
Post-cardiac arrest management will be conducted as per institutional protocols.

Primary Outcome Measures :
  1. Change in cytokine levels [ Time Frame: From baseline (randomization) to 72 hours after randomization ]
    Plasma levels reduction of the following inflammatory mediators: IL-1β,IL-1Ra, IL-6, IL-8, IL-10 and TNF-α.

  2. Incidence of Treatment-Emergent Adverse Events [ Time Frame: From beginning of hemoadsorption to 24 hours after the end of hemoadsorption, incidence of adverse events such as haemorrhagic complications, catheter-insertion related complications and anaphylactoid reactions ]
    Rate of intervention-related complications

Secondary Outcome Measures :
  1. Vasopressor requirements [ Time Frame: From baseline (randomization) to 72 hours after randomization ]
    Including the number of patients with a 50% decrease in the baseline vasopressor dose after 6, 12, 24, 36 and 48 hours, and the % of patients requiring a vasopressor dose increase within 24 hours of baseline

  2. In-hospital mortality [ Time Frame: Day 14, 28 and 90 after randomization ]
    All-cause mortality

  3. Shock reversal [ Time Frame: Within 24 hours from randomization ]
    Percentage of patients with shock reversal shock reversal being defined in the present study as a norepinephrine dose <0.1μg/kg/min to maintain MAP >60-70 mmHg and a serum lactate level ≤2 mmol/L

  4. Sequential Organ Failure Assessment Score (SOFA) [ Time Frame: Day 1 to 7 after randomization ]
    Total Daily SOFA Score. The score ranges from 0 (best outcome) to 24 (worst outcome).

  5. CRP and Procalcitonin Levels [ Time Frame: Day 1, 2, 3 after randomization ]
