New trial tests deep sleep vs. strong meds for hidden seizures
NCT ID NCT05263674
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.

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).
