Established Status Epilepticus Treatment Trial

Phase 3
Completed
Conditions
Benzodiazepine Refractory Status Epilepticus
Interventions
Registration Number
NCT01960075
Lead Sponsor
University of Virginia
Brief Summary

The primary objective is to determine the most effective and/or the least effective treatment of benzodiazepine-refractory status epilepticus (SE) among patients older than 2 years. There are three active treatment arms being compared: fosphenytoin (FOS),levetiracetam (LEV), and valproic acid (VPA).

The second objective is comparison of three drugs with respect to secondary outcomes.

The final objective is to ensure that the trial is informative for treatment of established SE in children by describing the effectiveness, safety, and rate of adverse reactions of these drugs in children.

Valproic acidValproic acidAdminister 40 mg/Kg valproic acid intravenously up to a maximum dose of 3000 mg (75 Kg) over 10 minutes. Those weighing more than 75 Kg receive a fixed dose of 3000 valproic acidover 10 minutes.
Fosphenytoin (FOS)FosphenytoinAdminister 20 mg/Kg fosphenytoin intravenously up to a maximum dose of 1500 mg ( 75 Kg) over 10 minutes. Those weighing more than 75 Kg receive a fixed dose of 1500 fosphenytoin over 10 minutes.
LevetiracetamLevetiracetamAdminister 60 mg/Kg levetiracetam intravenously up to a maximum dose of 4500 mg ( 75 Kg) over 10 minutes. Those weighing more than 75 Kg receive a fixed dose of 4500 levetiracetam over 10 minutes.
Primary Outcome Measures
NameTimeMethod
Number of Participants With Clinical Cessation of Status Epilepticus - Intention to TreatWithin 60 minutes after the start of study drug infusion

Determined by the absence of clinically apparent seizures and improving consciousness at 1 hour without other anticonvulsant medications. Intention to treat

Number of Participants With Clinical Cessation of Status Epilepticus - Adjudicated Outcomes AnalysisWithin 60 minutes after the start of study drug infusion

Determined by the absence of clinically apparent seizures and improving consciousness at 1 hour without other anticonvulsant medications. The Adjudicated outcomes analysis is different from Outcome measure 1 because a central clinical phenomenology core of four neurologists adjudicated from the medical records the time to seizure cessation, the time in status epilepticus before trial-drug initiation, and the cause of the seizure. For each enrollment, two neurologists from this core group conducted independent initial reviews and then determined a consensus or consulted a third adjudicator, as needed. Adjudicators were unaware of the treatment assignments and made determinations by medical record review.

Number of Participants With Clinical Cessation of Status Epilepticus - Per-protocol AnalysisWithin 60 minutes after the start of study drug infusion

Determined by the absence of clinically apparent seizures and improving consciousness at 1 hour without other anticonvulsant medications. Per-protocol analysis

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Admission to Intensive Care UnitAdmission to intensive care unit after start of study drug infusion, where the ICU is the initial inpatient unit for the patient

ICU admission is recorded as occurring only if the ICU is the initial inpatient unit for the patient.

Length of ICU Staynumber of calendar days after the day of ED arrival until hospital discharge or subject end-of-study

Length of stay is determined by the number of calendar days after the day of ED arrival until hospital discharge or subject end-of-study.

Minutes From Start of Trial Drug Infusion to Termination of Seizures for Patients With Treatment Successstart of drug infusion to seizure cessation

The time to termination of seizures is the interval from the start of study drug infusion to cessation of clinically apparent seizure in those who meet the primary outcome.

Number of Participants With Seizure Cessation Within 20 Minutes for Patients With Treatment Successwithin 20 minutes

Number of participants with seizure cessation within 20 minutes of study drug initiation for patients with treatment success. This outcome measure was only reported in the Supplementary materials to the Primary Paper.
