Comparing fast sedation to high-dose anti-seizure medication for non-convulsive status epilepticus

Fast Acute Sedation at Intensive Care vs. High-dose i.v. Anti-seizure Medication for Treatment of Non-convulsive Status Epilepticus (FAST-trial)

Phase 3 Interventional University of Southern Denmark · NCT05263674

This study is testing whether quick sedation or high-dose anti-seizure medication works better for adults with non-convulsive status epilepticus who haven’t responded to regular treatments.

What this trial studies

This open-label, randomized multicenter trial investigates the treatment options for patients suffering from non-convulsive status epilepticus (NCSE) who do not respond to standard therapies. Participants will be randomized into two groups: one receiving rapid sedation at intensive care and the other receiving high-dose intravenous anti-seizure medication. The study aims to clarify which approach is more effective in controlling seizures and improving patient outcomes. The trial will include adult patients with EEG-verified NCSE and will assess treatment efficacy based on clinical parameters.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years with EEG-verified non-convulsive status epilepticus who have not responded to benzodiazepines and at least one second-line intravenous anti-seizure medication.

Not a fit: Patients with acute neuroinfection, intracranial hemorrhage, or other specific contraindications to the treatments will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment protocol for patients with non-convulsive status epilepticus, potentially reducing mortality rates.

How similar studies have performed: While there is limited evidence-based guidance for treating non-convulsive status epilepticus, this approach is novel and aims to clarify treatment strategies that have not been rigorously tested in a randomized setting.

Eligibility criteria
