  2. Maximum Seizure Free Period

    The maximum seizure free period over the last 3 months will be collected

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

  3. Seizure Severity

    Seizure severity is a categorical outcome and will be rated by the subject using the following categories: Very mild, Mild, Moderate, Severe, Very Severe

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

  4. Post-ictal Severity

    Seizure severity is a categorical outcome and will be rated by the subject using the following categories: Very mild, Mild, Moderate, Severe, Very Severe

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

  5. Change in Quality of Life

    Quality of life is a categorical outcome and will be rated by the subject using the following categories: Very good: could hardly be better, Pretty good, Good and bad parts about equal, Pretty bad, Very bad: could hardly be worse

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

  6. Quality of Sleep

    Quality of sleep will be reported using the Pittsburgh Sleep Quality Index for subjects 18 years and older and using the Children's Sleep Habit Questionnaire for subjects 2-17 years old; quality of sleep will not be assessed in children under 2 years old

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

  7. Anti-epileptic Drug Use

    The name and dose of anti-epileptic drugs used will be collected on a case report form

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

  8. Rescue Drug Use

    The number of times a rescue drug was used will be collected

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

  9. Seizure Related Emergency Department Visits

    The number of times a patient had a seizure related emergency department (ED) visit will be collected

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

  10. Seizure Related Hospitalizations

    The number of times a patient had a seizure related inpatient hospitalization and the length of each stay will be collected

    Measured: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable

Questions about this trial

What is this clinical trial studying?

An observational study of Epilepsy and Seizures, run by LivaNova at 62 sites in 16 countries.

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 3 inclusion and 1 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 22 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 62 sites in United States, United Kingdom, Australia, Canada, China and 11 more countries. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Seizure Frequency (time frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable). The study lists 10 primary outcomes in all. 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 NCT03529045, which also lists 9 linked publications.

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 22 Nov 2024; AzTrials last refreshed its copy on 8 Nov 2026.
