A 19-week Cognition Study of Levetiracetam in Children With Partial Onset Seizures

February 27, 2015 updated by: UCB Pharma

A 19-week, Randomized, Double-blind, Multicenter, Placebo-controlled Safety Study to Evaluate the Cognitive and Neuropsychological Effects of Levetiracetam 20 - 60 mg/kg/Day, Divided in Twice Daily Dosing, as Adjunctive Treatment in Children 4 - 16 Years Old, Inclusive, With Refractory Partial Onset Seizures

A 12-week Evaluation Period will be used to characterize potential cognitive and neuropsychological effects of LEV (20 - 60 mg/kg/day), as adjunctive treatment in children 4 - 16 years old, inclusive, with refractory partial onset seizures when compared to adjunctive treatment with placebo.

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

4 years to 16 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Pediatric subjects (4 - 16 years old) diagnosed with refractory partial onset seizures for a minimum of six months prior to Visit 1 experiencing at least two partial onset seizures during the four weeks prior to Visit 1 will be enrolled
  • Subjects should be on a stable regimen of one or a maximum of two other antiepileptic drugs (AEDs) for at least 2 weeks prior to Visit 1
  • Subject must have an Intelligence Quotient (IQ) as assessed during Visit 1 of at least 70
  • Subject and parent/guardian should be fluent in English

Exclusion Criteria:

  • Subject must not have had previous treatment with levetiracetam unless, in the opinion of the investigator, the subject's previous treatment was inadequate in dose or duration to provide an accurate assessment of the therapy, or the effect of levetiracetam was confounded by concomitant medication
  • Subject is receiving benzodiazepines on a routine or chronic basic and is unable to discontinue use four weeks prior to Visit 1
  • Subject has seizures too close together to accurately count
  • Subject has a current psychiatric disorder other than mild to moderate attention deficit, behavior, or learning disorders

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.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in the Leiter International Performance Scale-Revised (Leiter-R) Attention and Memory (AM) Battery's Memory Screen Composite Score from Baseline (Visit 2) to the end of the Evaluation Period (Week 12 or Early Discontinuation Visit)
Time Frame: Baseline (Visit 2) to the end of the Evaluation Period (Week 12 or Early Discontinuation Visit)
The Leiter-R includes two groupings of sub-tests: (1) the Visualization and Reasoning (VR) Battery with 10 sub-tests of nonverbal intellectual ability related to visualization, reasoning, and spatial ability; and (2) the Attention and Memory (AM) Battery with 10 sub-tests of nonverbal attention and memory function. The Examiner Rating Scale has 49 items that describe the child's activity level, attention, impulse control, and other emotional characteristics that may interact with test performance. The focus of the items is on actions, verbalizations, moods and other behaviors of the child. The examiner rates the child using the following scale: 0 = rarely or never; 1 = sometimes; 2 = often; 3 = usually or always.
Baseline (Visit 2) to the end of the Evaluation Period (Week 12 or Early Discontinuation Visit)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Wide Range Assessment of Memory and Learning-Second Edition (WRAML-2) General Memory from Baseline to Week 12 or Early Discontinuation Visit (EDV)
Time Frame: Baseline to Week 12 or EDV
The WRAML-2 is comprised of 2 Verbal, 2 Visual, and 2 Attention-Concentration sub-tests, yielding a Verbal Memory Index, a Visual Memory Index and an Attention-Concentration Index. Together these sub-tests yield a General Memory Index. Scaled and standard scores allow performance comparisons based on age and 4 delayed recall sub-tests include guidelines for determining the level of recall. A composite General Memory Index score will be computed.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
