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

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.

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

12 years to 65 years (ADULT, OLDER_ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  2. Has an established diagnosis of partial or generalized epilepsy that includes all the following:

    • A documented history of seizure clusters lasting a minimum of 10 minutes, seizure cluster pattern is observable, stereotyped, and recognizably different from the subject's other non-cluster seizure activity (if any)
    • A second seizure in the seizure cluster typically occurs within 6 hours from the time of recognition
    • A seizure cluster pattern composed of multiple (≥ 2) partial or generalized seizures
    • A seizure cluster pattern established >3 months before Visit 1
    • A frequency of ≥ 3 stereotyped seizure clusters during the year before Visit 1
    • At least 1 stereotyped seizure cluster occuring ≤ 4 months before Visit 1
  3. Currently on a stable regimen of AED(s) that includes a benzodiazepine
  4. Weight is 40 kg to 125 kg, inclusive

Exclusion Criteria:

  1. Has a neurological disorder that is likely to progress in the next year
  2. Has a severe chronic cardio-respiratory disease

  4. Has a history of their stereotypical seizure cluster progressing to status epilepticus within 2 years before Visit 1
  5. Has a history of acute narrow-angle glaucoma
  6. Has had active suicidal plan/intent or active suicidal thoughts in the 6 months before Visit 1 or a suicide attempt in the past 5 years

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
Number of Participants With Death, Serious Adverse Events, Treatment Emergent Adverse Events (TEAEs) Leading to Discontinuation
Time Frame: Duration of individual subject participation was open-ended. Study ended early. Longest subject participation approximately 6 months.
Number of Participants with Death, Serious Adverse Events, Treatment emergent adverse events (TEAEs) leading to subject discontinuation from study
Duration of individual subject participation was open-ended. Study ended early. Longest subject participation approximately 6 months.

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
Treatment Success
Time Frame: Duration of individual subject participation was open-ended. Study ended early. Longest subject participation approximately 6 months.
Termination of seizure(s) within 10 minutes and no recurrence within 6 hours after study drug administration. Due to early termination of the study, this data was not analyzed.
Duration of individual subject participation was open-ended. Study ended early. Longest subject participation approximately 6 months.

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.
