About this study

Almost all patients with refractory cardiac arrest, who are primarily stabilized under ongoing cardiopulmonary resuscitation by transcutaneous implantation of a venoarterial extracorporeal membrane oxygenation system (va-ECMO for eCPR) develop post-cardiac arrest syndrome (PCAS). PCAS is characterised by cytokine storm resulting in vasodilation and membrane leakage, which is poorly controlled and often fatal. Case reports and data from the investigators' single-center registry indicate that cytokine adsorption with the CytoSorb removal column can be safely added to va-ECMO, but its efficacy and safety have not been examined systematically. This pilot study will assign all comers undergoing eCPR to va-ECMO with or without cytokine adsorber in a 1:1 fashion. This will ensure comparability and allow analysing clinical endpoints, but is limited by sample size (according to their experience the investigators expect approximately 20 cases per year). The investigators will however be able to generate important data about safety, secondary endpoints such as Interleukin-6-removal or vasopressor use and low-power data about efficacy concerning the primary endpoint 30-day survival.

Read the detailed description

Survival after out-of-hospital cardiac arrest (OHCA) as well as intra-hospital cardiac arrest (IHCA) is poor and remains on low levels over the past decades. Introduction of eCPR has promised to improve survival, however, so far there is no supporting data for this claim. In a recent registry study at the investigators' hospital they determined survival rates of 8.5% (OHCA) and 18.9% (IHCA), respectively. Almost all patients with refractory cardiac arrest, who are primarily stabilized under ongoing cardiopulmonary resuscitation by transcutaneous implantation of a veno-arterial extracorporeal membrane oxygenation system (va-ECMO for eCPR) develop post-cardiac arrest syndrome (PCAS). PCAS is characterised by cytokine storm resulting in vasodilation and membrane leakage, which is poorly controlled and often fatal. Case reports and data from the investigators' single-center registry indicate that cytokine adsorption with the CytoSorb removal column can be safely added to va-ECMO, but its efficacy and safety have not been examined systematically.

First, the investigators aim to assess the influence of treatment with the CytoSorb removal column over 72 hours after cardiac arrest and resuscitation using eCPR on 30-day-survival. As secondary endpoints, the investigators will assess the efficacy of Interleukin-6-removal, vasopressor-use and fluid-substitution, the latter two as a subsidiary of the degree of PCAS. Finally, the investigators will asses the safety of the use of the CytoSorb column in eCPR/va-ECMO.

The investigators hypothesize that the use of the CytoSorb column in eCPR/va-ECMO is a safe and efficient means to manage the consequences of PCAS and thus reduce 30-day mortality after eCPR.

All patients admitted to the investigators' hospital after successful CPR and implantation of va-ECMO/ ECLS (extracorporeal life support, eCPR) will be included in the trial. In a 1:1 manner participants will be assigned to the intervention and control groups.

Experimental intervention:

In addition to standard treatment in patients undergoing eCPR in the intervention group the CytoSorb removal column will be added to the ECLS-system.

Control intervention:

Patients in the control group will receive standard treatment established for eCPR patients on our ICU. This standard treatment includes, among others, targeted temperature management (TTM) for the first 72 hours. For the use of ECLS as well as TTM we are following well established standard operating procedures.

Duration of intervention per patient:

The duration of the intervention will be 72 hours. Each CytoSorb removal column can be used for 24 hours, so all patients in the intervention group will receive 3 subsequent filters during the study period.

Follow-up per patient:

The follow-up period for each patient in the trial will be 30 days.

Key inclusion criteria:

All patients admitted to our ICU after successful CPR undergoing eCPR will be included in the trial.

Key exclusion criteria:

The single exclusion criteria for the trial is, if decision has been made before admission to our ICU to terminate treatment within the next 24 hours.

The record lists 1 site in Germany. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

survival after 30 days (time frame: 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03685383, which also lists 1 linked publication.

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 15 Mar 2021.
