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

Short summary

This open-label, randomized multicenter trial aims at clarifying the standard of care of patients with non-convulsive status epilepticus not responding to treatment with benzodiazepines and at least one high-dose intra venous anti-seizure medication.


Persistent epileptic seizures, aka. status epilepticus (SE), are the second most common neurological cause of acute admissions. Around halv of the patients suffers from SE without prominent visible seizures ("convulsions"), which is referred to as non-convulsive status epilepticus (NCSE) and is afflicted with a long-term mortality of >50% also in patients without concomittant acute brain disease. There are no evidence-based treatment guidelines for NCSE but patients usually receive treatment with benzodiazepines followed by i.v. anti-seizure medication. If seizures continues, further treatment is controversial. The participating centers have long-standing experience in treating NCSE but use different, internationally accepted treatment strategies. Some initiate aggressive treatment with fast sedation at intensive care aiming at immediate seizure control, other estimate that the side effects of sedation does not outweigh the potential benefit and try high-dose i.v. anti-seizure medication that only slightly impair conciousness - often with success.

This randomized, open label, multicenter trial (Eudract 2021-003392-34) aims at clarifying the treatment of patients with NSCE not responding to standard therapy. Patients with verified NCSE based on clinical parameter or using electroencephalography (EEG) are randomized into a fast acute sedation group and a group that receives at least one additional, high-dose anti-seizure medication.

Primary objective endpoint is treatment failure 24 h after randomization as determined by EEG. Secondary endpoints are e.g. seizure-induced neurological damage, treatment-related complications and neurological long-term outcome.
