Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

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

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • Currently being treated with an antiepileptic drug(s) (AED).
  • Benzodiazepines are allowed with some frequency restrictions.
  • Vagus nerve stimulation is allowed if in place for at least 6 months prior to starting the study with no changes to the settings having occured during the month immediately prior to starting the study, and if no changes will occur during all phases of the study.
  • History of primary generalized tonic-clonic seizures with no focal onset.
  • Have at least 1 primary generalized tonic-clonic (PGTC) seizure during the 8 consecutive weeks prior to the baseline period of the study.
  • Have at least 3 PGTC seizures occur anytime during the 8-week baseline phase of the study.
  • Females must agree to acceptable form of birth control.

EXCLUSION CRITERIA:

  • A history of partial seizures or interictal expression of partial seizures as evidenced by electroencephalogram.
  • Have Lennox-Gastaut syndrome.
  • Currently using or has previously used the drug being studied.
  • Is abusing alcohol and/or other substance(s).
  • Has taken an investigational drug during the 30 days prior to the study or plans to take an investigational drug anytime during the study.
  • Is receiving chronic (long-term) treatment with any medication that could influence seizure control.
  • Follows the ketogenic diet.
  • Is planning surgery to control seizures during the study.
  • Is suffering from acute or progressive neurological disease, severe psychiatric disease, or severe mental abnormality.
  • Has any clinically significant heart, kidney, or liver condition, or a condition that affects how drugs are absorbed, distributed, metabolized, or removed from the body.

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
% change from Baseline in average monthly PGTC seizure frequency

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
Proportion of subjects with >/= 25%, 50%, 75% or 100% reduction in PGTC seizures %change from Baseline in average monthly seizure frequency.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2000

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.
November 1, 2003

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
