Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The study population consists of approximately 1,500 adult male and female patients with diagnosed focal-onset (partial-onset) seizures across multiple institutes/hospitals in Pakistan. Participants will include newly diagnosed, treatment-naïve patients and patients previously treated with carbamazepine or oxcarbazepine who have inadequate seizure control or intolerable adverse effects. Eslicarbazepine treatment will be initiated or switched at the discretion of the treating physician in accordance with routine clinical practice and applicable prescribing information.

Who may be able to join

  • Adult patients (aged at least 18 years) with diagnosed partial-onset seizures.
  • Newly diagnosed (treatment-naïve) or previously treated with Carbamazepine or Oxcarbazepine and inadequately controlled or intolerant.
  • Patient or Legal Representative is willing and able to provide informed consent, or, in the absence of a legal representative, an Independent Healthcare Professional provides authorization for patient enrolment.

Who cannot join

  • Any hypersensitivity to Eslicarbazepine.
  • Female patients who are pregnant or lactating.
  • Patients who have a contraindication to the medicine or any component of prescribed therapy.

About this study

Official title: A Prospective, Real-World Evidence, Multicenter Study to Evaluate the Efficacy and Safety of Eslicarbazepine in Managing Epilepsy

This prospective multicenter observational study will evaluate the effectiveness, safety, tolerability, and impact on quality of life of eslicarbazepine in adults with focal-onset seizures in routine clinical practice. Participants will include newly diagnosed patients and patients previously treated with carbamazepine or oxcarbazepine who have inadequate seizure control or intolerable adverse effects. Treatment with eslicarbazepine will be initiated or changed at the discretion of the treating physician in accordance with routine clinical practice. Participants will be followed for 3 months.

Read the detailed description

This prospective, multicenter observational study will assess the effectiveness, safety, and tolerability of eslicarbazepine in adults with focal-onset epilepsy, including newly diagnosed patients and patients previously treated with carbamazepine or oxcarbazepine who have inadequate seizure control or intolerable adverse effects.

Treatment decisions, including the decision to initiate eslicarbazepine or switch from another antiseizure medication, will be made by the treating physician according to routine clinical practice and the approved product information. The study will therefore observe outcomes associated with eslicarbazepine use without assigning participants to treatment.

Eslicarbazepine will be administered orally once daily. Newly diagnosed patients will typically start at 400 mg/day and increase to 800 mg/day after one week. Patients switching from carbamazepine or oxcarbazepine may start at 400-600 mg/day according to clinical judgment and may undergo an overnight switch or cross-titration. If clinically indicated and tolerated, the dose may be increased to a maximum of 1600 mg/day. Dose adjustments will be guided by tolerability, seizure control, and adverse-event monitoring.

Participants will be assessed at baseline, Day 7, and Month 3. Data collected will include demographic and clinical information, concomitant medications, seizure occurrence and frequency, quality of life using the Patient Quality of Life in Epilepsy (QOLIE-10-P) questionnaire, treatment compliance, and adverse events and serious adverse events.

The study will include approximately 1500 participants from multiple institutes/hospitals across Pakistan.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Eslicarbazepine acetateDrug

    Eslicarbazepine acetate administered orally once daily as prescribed by the treating physician in routine clinical practice. Newly diagnosed patients will typically initiate treatment at 400 mg/day and increase to 800 mg/day after one week. Patients switching from carbamazepine or oxcarbazepine may initiate treatment at 400-600 mg/day according to clinical judgment. Dose adjustments, including increases up to 1600 mg/day when clinically indicated and tolerated, will be determined by the treating physician.

What is being measured

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

  1. Change in Seizure Frequency

    Measured: From Baseline to Month 3

  2. Seizure Response Rate

    Measured: From Baseline to Month 3

Secondary outcomes (2)
  1. Change in QOLIE-10-P Score

    Patient Quality of Life in Epilepsy Score has 10 questions being scored 1 to 5 each with lower score indicating poorer quality of life and higher score indicating better quality of life with total score ranging from 10 to 50. An increase in score indicates improvement in quality of life.

    Measured: From Baseline to Month 3

  2. Adverse Events and Serious Adverse Events

    Measured: From Baseline through Month 3

Where is the study taking place?

The record lists 1 site in Pakistan. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Safia Assistant Professor Neurology, FCPS Neurology, PhD Scholar (+92-301-4154276, safiabano@kemu.edu.pk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Seizure Frequency (time frame: From Baseline to Month 3). The study lists 2 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 NCT07793396, which also lists 17 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.
