Levetiracetam to Prevent Post-Traumatic Epilepsy

December 11, 2015 updated by: Pavel Klein

Pilot: Levetiracetam to Prevent Post-Traumatic Epilepsy

Head injury is the cause of approximately 5% of all epilepsy in the US. Past attempts at preventing epilepsy by treatment with older antiepileptic drugs have been unsuccessful. Levetiracetam is a novel AED with potent antiepileptogenic properties in animal models of epilepsy. It has a favorable side effect and pharmacokinetic profile. It is therefore a strong candidate for a clinical trial of epilepsy prevention following traumatic brain injury (TBI). However, there has been no experience in administering levetiracetam rapidly to individuals with acute TBI. The investigators propose to initiate the evaluation of levetiracetam in prevention of post-traumatic epilepsy by determining the safety, tolerability, pharmacokinetics and feasibility of acute and chronic administration of levetiracetam to individuals with head injury with a high risk for developing post-traumatic epilepsy. Further, the investigators will follow subjects for 2 years after injury in order to obtain pilot data about effect of levetiracetam on PTE. This pilot study is the first step in evaluation of levetiracetam in prevention of post-traumatic epilepsy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

    • Use of Antiepileptic Drugs (AEDs) within two months of enrollment, for any indication.
    • Allergy/sensitivity to study drugs or their formulations:
    • Active drug or alcohol dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements:
    • Inability or unwillingness of subject or legal guardian/representative to give written informed consent.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Levetiracetam
66 subjects with acute head injury with a high risk for developing post-traumatic epilepsy will receive levetiracetam 55 mg/kg/day in a b.i.d. schedule. Treatment will commence within 8 hours of the acute head injury and will last for 30 days. In addition, subjects will receive phenytoin for 1 week following head injury as standard clinical care.
Drug: Levetiracetam
55 mg/kg/day given in 2 divided doses 12 hours apart
Other Names:
  • Keppra (brand name)
No Intervention: No Intervention Control
60 subjects with acute head injury with a high risk for developing post-traumatic epilepsy enrolled 8-24 hours after injury will not receive levetiracetam. Subjects will receive phenytoin for 1 week following head injury as standard clinical care.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
