For Phenobarbital and Phenobarbital derivatives, a minimum of 4 weeks wash-out is requested before V1

Who cannot join

  • Subject has a current or previous diagnosis of pseudoseizures, conversion disorders, or other non-epileptic ictal events which could be confused with seizures
  • Subject taking 1 or more of the following medications on a regular basis within 28 days prior to Visit 1: neuroleptics, monoamine oxidase (MAO) inhibitors and narcotic analgesics
  • Subject taking any immunosuppressant within 28 days prior to Visit 1
  • Subject has a history of suicide attempt, has received professional counseling for suicidal ideation, or is currently experiencing active suicidal ideation

  • Subject suffering from seizures other than partial (IA, IB, IC, with clear focal origin) seizures
Show all 9Show fewer
  • Subject has a history of status epilepticus within last 3-month period prior to Visit 1
  • Subject has seizures that are uncountable due to clustering (ie, an episode lasting less than 30 minutes in which several seizures occur with such frequency that the initiation and completion of each individual seizure cannot be distinguished) during the 12-week period prior to Visit 1 and/or during the Screening Period
  • Body weight is lower than 40 kg (< 40 kg)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Subjects With a Treatment Failure

    Treatment failure is defined as (1) Dropout due to related intolerable adverse event, lack of efficacy or need for addition of another Antiepileptic Drug (AED), or (2) need of a 1-step down-Titration, within 50 weeks from the first dose of study medication.

    Measured: Week 0 (First Dose) to Week 50

Secondary outcomes (3)
  1. Time to the First Seizure Defined as the Time From the First Dose of Medication to the Occurrence of the First Seizure During the 48 Weeks Treatment Period

    Measured: From Week 2 to Week 50 (During Treatment Period )

  2. Percentage of Subjects Who Achieved Seizure Freedom for 24 Consecutive Weeks During the 48 Weeks Treatment Period at Any Time

    24-week Seizure Freedom (rate) defined as the number and percentage of subjects who achieved seizure freedom for 24 consecutive weeks during the Treatment Period at any time

    Measured: From Week 2 to Week 50 (During Treatment Period )

  3. Percentage of Subjects Who Achieved Seizure Freedom During the 48 Weeks Treatment Period

    48-week Seizure Freedom (rate) defined as the number and percentage of subjects who achieved seizure freedom during the Treatment Period

    Measured: From Week 2 to Week 50 (During Treatment Period )

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Levetiracetam and Oxcarbazepine in people with Epilepsy, run by Korea UCB Co., Ltd. at 23 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Aug 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Subjects With a Treatment Failure (time frame: Week 0 (First Dose) to Week 50). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01498822, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2015.
