Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

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.

Summary

This study tests whether putting people into a deep sleep with strong sedatives works better than giving more seizure drugs for a serious condition called non-convulsive status epilepticus (NCSE). In NCSE, the brain has ongoing seizure activity without obvious shaking. The trial will include 140 adults who did not get better with standard treatments. Researchers will check if the seizures stop within 24 hours and track any side effects.

What this could mean

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

Active substance
Propofol (with possible low-dose Midazolam)
What this could lead to
If successful, this could establish a more effective standard treatment for a serious seizure emergency, potentially reducing brain damage and complications.
What could go wrong
This is a Phase 3 trial but still relatively small (140 participants). Deep sedation carries risks like breathing problems or infections, and the results may not apply to all patients.

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

Inclusion Criteria: * Adult patients (older than 18 years) with EEG-verified NCSE, according to the Salzburg criteria, who have not responded to appropriate treatment with benzodiazepines and at least one 2nd line i.v. anti-seizure medication according to the current Danish national neurological treatment guidelines (Levetiracetam, Fosfenytoin or Valproate).
