Study summary

The primary objective is to demonstrate the superiority of arginine-vasopressin (AVP) and hydrocortisone compared with norepinephrine regarding day-30 survival and neurological recovery in post-cardiac arrest patients with hemodynamic failure.

Read the detailed description

For patients successfully resuscitated who got restoration of spontaneous circulation (ROSC) after cardiopulmonary resuscitation (CPR), the course is usually marked by a post-resuscitation syndrome including multiple organ failures of various intensity and anoxic brain damage. The cardiocirculatory failure usually dominates the clinical picture, and it often leads to multiorgan failure. This hemodynamic failure is multifactorial, including at various levels vasoplegia, myocardial dysfunction, endotoxin release and adrenal dysfunction and is at least partly related to a hormonal defect that could be counteracted by hormonal supplementation. Such a substitutive opotherapy by hydrocortisone and AVP could improve hemodynamic failure and decrease overall mortality in this setting.

This trial is a superiority multicentric trial and patients will be randomized in a 1:1:1:1 ratio using an electronic CRF.

Investigational medicinal products:

  • Arginin-vasopressin or AVP (REVERPLEG) The solution for infusion is prepared by diluting 40 I.U. REVERPLEG® with sodium chloride 9 mg/ml (0.9%) solution. The total volume after dilution should be 50 ml (equivalent to 0.8 I.U. AVP per ml).

AVP will be administered according to mean arterial pressure to target a 65mmHg blood pressure for max 3 days.

  • HYDROCORTISONE HEMISUCCINATE Vials with lyophilisate (100mg hydrocortisone) are provided by SERB laboratory. Hydrocortisone hemisuccinate will be administered as a 50mg intravenous bolus every 6 hours after an initial dose of 100mg, for 7 consecutive days. Stop of treatment by hydrocortisone will be performed without tapering.

Comparator treatment: placebos.

17 ICU centers in France will participate to this study targetting 380 patient's enrollment in the study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adult patients (>18y)
  • Cardiac arrest (in-hospital or out-of-hospital) with sustained ROSC (> 30 minutes) admitted to the ICU
  • Post-resuscitation shock defined as arterial hypotension (SAP \< 90 mmHg or MAP \< 65 mmHg) unresponsive to adequate fluid loading, which occurred within the first 24 hours after ROSC and requiring norepinephrine/epinephrine continuous infusion at a dose greater or equal to 0.2µg/kg/min for at least 3 hours
  • A maximal delay between the start of norepinephrine infusion and randomization of 9 hours
  • Informed written consent of the patient or a legally authorized close relative.

Exclusion criteria

Exclusion Criteria:

  • Evidence for a traumatic or a neurological cause of cardiac arrest
  • Shock due to uncontrolled haemorrhage
  • Previously known adrenal insufficiency
  • Limitation of life-sustaining therapies
  • Ongoing treatment by any , whatever the dose
  • Ongoing extra-corporeal circulatory assistance
  • Gastrointestinal bleeding in the past 6 weeks
  • Pregnant or breastfeeding women
  • Participation in another interventional study involving human participants or being in the exclusion period at the end of a previous study involving human participants, if applicable
  • to arginin-vasopressin and to its
  • Hypersensitivity to hydrocortisone and to its excipients
  • Legal protection (i.e. incompetence to provide consent, guardianship, curator or incarceration)
  • No affiliation with the French health care system.
Terms in these criteria, in plain language(3)

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

What researchers measure

Primary outcomes

  1. Neurological outcome

    The primary endpoint will be the good neurological outcome at day-30. This will be evaluated using the Glasgow Outcome Scale (GOS, addendum 18.5.1) dichotomized as follow: good neurological outcome for categories 4 and 5 and poor neurological outcome or death for categories 3, 2 and 1. The GOS will be obtained at day-30 from an in-hospital visit if the patient is still hospitalized or from telephone contact with patients, relatives or general practitioners.

    Time frame: at day-30

Secondary outcomes

  1. All-cause mortality

    Vital status at day-30.

    Time frame: at day-30

  2. Mortality attributed to irreversible hemodynamic failure

    Time to irreversible cardiovascular failure defined as death in pharmacologically uncontrollable hypotension (mean arterial blood pressure \< 60 mmHg) despite maximal ICU care, or withdrawal of care based on same, as previously defined (Witten L, Resuscitation 2019).

    Time frame: at day-30

  3. Mortality attributed to neurological withdrawal of care

    Time to neurological withdrawal of care. Withdrawal of care will be based on expectations of a poor neurological recovery based on most recent guidelines (Sandroni C, ICM 2015).

    Time frame: at day-30

  4. Mortality attributed to comorbid withdrawal of care

    Time to comorbid withdrawal of care. Comorbid withdrawal of care or refusal of life-sustaining therapy based on the expectation of a poor quality of life. This may be related to a preexisting or newly discovered terminal illness or other serious medical condition (e.g. dementia or cancer).

    Time frame: at day-30

  5. Day-30 brain death

    Time to brain death (according to French legislation)

    Time frame: at day-30

  6. mortality attributed to recurrent cardiac arrest

    Time to recurrent cardiac arrest

    Time frame: at day-30

  7. Other causes

    Proportion of patients dead from a cause not listed above.

    Time frame: at day-30

  8. Neurological recovery at day-30

    Glasgow outcome score - extended at day-30. This score will be evaluated similarly to the primary endpoint

    Time frame: at day-30

  9. Brain damage

    Neuron-specific enolase (NSE) blood level measured 48 and 72 hours after CA

    Time frame: at 48 hours and at 72hours

What these dates mean
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 Jun 12, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
