An add-on Study of E2007 in Patients With Refractory Partial Seizures Uncontrolled With Other Anti-epileptic Drugs (AEDs)

January 3, 2013 updated by: Eisai Co., Ltd.

A Phase II, Open-label, Ascending High-dose, add-on Study of E2007 in Patients With Refractory Partial Seizures Uncontrolled With Other Anti-epileptic Drugs (AEDs)

The purpose of this study is to explore the maximum tolerated dose of E2007 in Japanese patients with refractory partial seizures which are uncontrolled with other anti-epileptic drugs (AEDs). Thirty patients will receive E2007 (dose escalating to the maximum of 12 mg per day). The dose of E2007 will be adjusted during 6 weeks. Subsequently, the dose will be fixed and maintained during 4 weeks.

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

20 years to 64 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion criteria:

  1. Male or female aged between 20 and 64 years old.
  2. Patients diagnosed with partial seizure (including secondarily generalized seizure).
  3. Patients who have at least 3 counts of partial seizures during the previous 4 weeks prior to observation start and no seizure-free for 21 days during 8 weeks before the treatment start based on medical records. Simple partial seizure without motor signs will not be counted.
  4. Patients who have been treated for at least 12 weeks but confirmed to be uncontrolled with more than one standard AED for 2 years.

  5. Patients treated with stable doses of up to three AEDs. Only one cytochrome

    P450 (CYP) 3A4 inducer shown below will be allowed for concomitant use:

    • Carbamazepine
    • Phenytoin
    • Phenobarbital
    • Primidone
  6. Patients on stable dose of anti-depressants, anti-anxiety drugs, or mood stabilizers from before 8 weeks.

Exclusion criteria:

  1. Patients with present or a history of Lennox-Gastaut syndrome.
  2. Patients with present generalized seizures (e.g., absence, myoclonic).
  3. Patients with a history of status epilepticus within 1 year.
  4. Patients with seizure clusters where individual seizure cannot be counted within 8 weeks.
  5. Patients with a history of psychogenic seizure.
  6. Patients who underwent surgical operation for epilepsy within 2 years.
  7. Patients using rescue benzodiazepines at least twice in a 4-week duration within 8 weeks (if 1 or 2 doses over 24-hour period considered one-time rescue).
  8. Patients whose alanine aminotransferase (ALT) or aspartate aminotransferase (AST) at enrollment in observation period exceeds 1.5-fold the upper limit of normal (ULN), but those whose ALT or AST are constantly higher than ULN, they can enroll if ALT or AST remain in 3-fold the ULN.
  9. Patients with significant active hematological disease; white blood cell (WBC) count </=2500/uL or neutrophil count </=1000 uL.
  10. Patients on anti-psychotics or who have psychotic disorder and/or psychotic disorder(s) or unstable recurrent affective disorder(s) with a history of suicidal attempt within 2 years.
  11. Patients who operate heavy equipment or drive should not be recruited into the study.

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

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.
Experimental: 1
Drug: E2007
The dose of E2007 will start from 2 mg and will be increased by 2 mg every week up to 12 mg (the maximum dose). The dose will be adjusted during 6 weeks (i.e., titration period). Subsequently, the dose will be fixed and maintained during 4 weeks (Maintenance period). Patients must visit study site at Weeks -4, 1, 2, 3, 4, 5, 6, 8, 10 and 14 to confirm.

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
Maximum Tolerated Dose (MTD)
Time Frame: 10 weeks (Titration and Maintenance Periods)
MTD was defined by participants. For participants who completed treatment, MTD was dose at last administration. For subjects who discontinued due to adverse event (AE), the MTD depended on the number of days within down-titration. If these criteria were not applied, the MTD was determined based on suggestions from the Tolerability and Safety Evaluation Committee.
10 weeks (Titration and Maintenance Periods)

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
Percent Change in Total Seizure Frequency Per 28 Days From Baseline (Maintenance Period) ; LOCF
Time Frame: Baseline (Day -28 to Day 0), Week 1 to Week 10
The percent change in seizure frequency per 28 days during the maintenance period was collected via patient diary cards. This was calculated using the last observation carried forward (LOCF) method.
Baseline (Day -28 to Day 0), Week 1 to Week 10
