Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
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.
60

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

18 years to 64 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Subjects that are male or female aged 18 to 64 years (inclusive) with a body mass index between 18 and 35 (kg/m2)
  • Subjects must have a diagnosis and history of treatment resistant partial onset seizures for which they are taking 1 to 4 concomitant antiepileptic drugs (AED). Treatment resistance is defined as failure to achieve seizure freedom despite adequate use of 2 different AEDs. All AED doses must remain stable for 4 weeks prior to the Screening Visit and throughout the entire study
  • Subjects must have had at least 1 electroencephalogram (EEG) consistent with partial epilepsy and a brain magnetic resource imaging (MRI) or computed tomography (CT) scan within 5 years of Screening Visit negative for other confounding conditions
  • Subjects must have had at least 6 observable partial seizures in 6 weeks prior to randomization, with at least 1 seizure per week during 3 of the 6 weeks within the Baseline Period
  • Subjects who are male or female must agree to use acceptable contraceptive methods as defined in the protocol
  • Subjects who are in otherwise good health

Exclusion Criteria:

  • Subjects with a history of non-epileptic transient alterations in consciousness
  • Subjects who have a history of status epilepticus in the past 12 months
  • Subjects whose seizure frequency cannot be quantified
  • Subjects who have significant medical illness including kidney, liver, pulmonary or gastrointestinal disease; or unstable or poorly controlled conditions
  • Subjects who have clinically significant psychiatric illness
  • Subjects with a positive drug screen (excluding any allowed prescribed medications) and history of alcoholism or drug addiction within past 2 years
  • Males subjects that have a female partner of childbearing potential who do not agree to use medically approved methods of birth control
  • Male subjects that have a female partner who is pregnant, nursing, or is planning to become pregnant during the study period, or within 90 days of the last dose of study drug
  • Female subjects who are pregnant or lactating, or who are of reproductive potential who do not agree to use medically approved birth-control methods
  • Subjects with a current or prior history of illness precluding them from immunomodulatory therapy (e.g. history of recurrent infections)
  • Subjects with active hepatitis B, hepatitis C, or human immunodeficiency virus (HIV)
  • Subjects who have participated in any other clinical trials involving an investigational product or device and have received the last dose of study drug within 45 days or 5 half-lives of the Screening Visit

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

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.

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.

Study Completion (Actual)

Study Completion
