What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This trial studies whether giving anti-seizure medication to comatose patients who have brain seizure activity after cardiac arrest can improve their recovery. Participants are randomly assigned to receive either standard care alone or standard care plus a stepwise anti-seizure treatment. The study measures functional recovery and healthcare costs to see if the treatment makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
anti-seizure medication and sedative agents
What this could lead to
If effective, this approach could improve functional recovery and quality of life for comatose patients after cardiac arrest.
What could go wrong
This is a mid-stage trial with 150 participants, so results may not apply broadly. Anti-seizure drugs can cause side effects like sedation or low blood pressure.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 150 people

The number the study aims to enrol. It can still change while the study runs.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Coma (Glasgow Coma Scale score ≤ 8) after out of hospital cardiac arrest and resuscitation 2. Age ≥ 18 years 3. Continuous EEG with at least eight electrodes started \< 24h after return of spontaneous circulation (ROSC) 4. ESE or possible ESE according to the Salzburg and ACNS criteria 5. Possibility to start treatment within three hours after detection of ESE Exclusion Criteria: 1. Known history of another medical condition with limited life expectancy (\< six months) 2. Any progressive brain illness, such as a brain tumor or neurodegenerative disease 3. Pre-admission Glasgow Outcome Scale score of 3 or lower 4. Reason other than the neurological condition to withdraw treatment 5. EEG background activity prior to the emergence of ESE indicative of extensive irreversible anoxic brain injury 6. Follow-up impossible due to logistic reasons, for example not living in the Netherlands or Belgium
