About this study

Official title: Prevention of Epilepsy in Stroke Patients at High Risk of Developing Unprovoked Seizures: Anti-epileptogenic Effects of Eslicarbazepine Acetate

This study aims to assess if eslicarbazepine acetate (ESL) treatment (started within 96 hours after stroke occurrence and continued for 30 days) changes the incidence of unprovoked seizures (USs) within the first 6 months after randomisation as compared to placebo

Read the detailed description

This is a multicentre, double-blind, randomised, placebo-controlled, parallel-group trial in patients with acute intracerebral haemorrhage with a Cortical involvement, Age <65 years, Volume of intracerebral haemorrhage > 10 ml and Early seizure within 7 days after intracerebral haemorrhage (CAVE) score ≥ 3 or an acute ischaemic stroke with a SeLECT score ≥ 6.

At the first visit (screening/baseline, V1a), patients will undergo several examinations to check eligibility. The next visit (V1b) has to be performed within 96 hours after primary stroke occurrence. After eligibility has been confirmed, patients will be randomised (randomisation ratio 1:1) to treatment with ESL 800 mg (Group A) or placebo (Group B).

Patients will start treatment with the investigational medicinal product (IMP), i.e. ESL or placebo, within 96 hours after primary stroke occurrence at V1b. They will continue treatment until Day 30 after randomisation and then be tapered off. Thereafter, patients will be followed up until 18 months after randomisation. Patients can concomitantly receive antiepileptic therapies, except commercially available ESL or oxcarbazepine, until Day 30.

Concomitant antiepileptic therapies have to be discontinued and down-titration has to be started according to the respective Summary of Product Characteristics (SmPC). If the antiepileptic drugs (AEDs)/benzodiazepine are not already discontinued before, downtitration must be started on Day 31 at the latest.

If one or more AS(s) occur(s) within 7 days after primary stroke, this will not result in change of IMP dose. Patients having a first US will discontinue IMP treatment and will be treated at the discretion of the investigator until 18 months after randomisation, except with commercially available ESL.

Further visits will be performed 7 days (V2, on-site), 37 days (V3, on-site), 12 weeks (V4, telephone), 26 weeks (V5, on-site), 38 weeks (V6, telephone), 52 weeks (V7, on-site), 64 weeks (V8, telephone) and 78 weeks (End of Trial (EoT) visit, on-site) after V1b.

What is being measured

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

  1. Proportion of Patients Who Experience the First Unprovoked Seizures (US) Within the First 6 Months After Randomisation (Failure Rate)

    Deaths before the first US or patients without evaluable assessment of the primary endpoint will be counted as treatment failures. To show that ESL (Group A) is superior to placebo (Group B), the primary null hypothesis will be tested against the alternative hypothesis

    Measured: First 6 months after randomisation

Secondary outcomes (19)

  1. Proportion of Patients Who Experience the First US During the First 12 Months After Randomisation

    Deaths before the first US or patients without evaluable assessment of the primary endpoint will be counted as treatment failures. To show that ESL (Group A) is superior to placebo (Group B), the primary null hypothesis will be tested against the alternative hypothesis

    Measured: First 12 months after randomisation

  2. Proportion of Patients Who Experience the First US During the Course of the Trial

    Deaths before the first US or patients without evaluable assessment of the primary endpoint will be counted as treatment failures. To show that ESL (Group A) is superior to placebo (Group B), the primary null hypothesis will be tested against the alternative hypothesis

    Measured: Until 18 months after randomisation

  3. Number of Acute Symptomatic Seizure (ASS)

    Number of ASSs will be summarised by means of descriptive statistics

    Measured: During the first 7 days after stroke

  4. Probability of Failure at 6, 12, and 18 Months After Randomization

    The time to first US after randomisation will be analysed and presented by means of the Kaplan-Meier estimate after 6, 12 and 18 months for the failure time. The time to first US will be analysed from the day of randomisation.

    Measured: Over 18 months follow-up period

  5. Time to First US After Stroke Occurrence.

    Analysis of time to first US will be performed using the day of stroke (before randomisation) as Day 1.

    The secondary objective and endpoint "Time to first US after stroke occurrence" was decided to be deleted as it is closely related to the forth secondary endpoint "Time to first US after randomisation" and therefore would not really have any additional value.

    Measured: Over 18 months follow-up period

  6. Number and 4-week Rate of USs (4-week Rate of USs Was Omitted With SAP, Final Version 1.0, 22 NOV 2023).

    The total number and rate of USs, standardised per 4 weeks, in all patients and in patients with US(s) only will be summarised by means of descriptive statistics.

    The secondary objective and endpoint "4-week rate of USs" was decided to be deleted as this information will not be meaningful for this trial.

    Measured: Over 18 months follow-up period

  7. Barthel Index (BI) Original 10-item Version

    The Barthel Index at baseline and post-baseline visits of each patient will be calculated adding the individual scores from each item. Baseline is the value assessed before first IMP intake. Endpoint is the last non-missing value collected after the first IMP intake. The BI is a widely used score to measure the performance in activities of daily living of patients with stroke and other neuromuscular or musculoskeletal disorders in the following 10 categories:

    1. Feeding (scored as 0, 5, 10)
    2. Moving from a wheelchair to a bed and back again (scored as 0, 5, 10, 15)
    3. Personal hygiene (scored as 0, 5)
    4. Getting on and off the toilet (scored as 0, 5, 10)
    5. Self-bathing (scored as 0, 5)
    6. Walking on a level surface (scored as 0, 5, 10, 15)
    7. Ascending and descending stairs (scored as 0, 5, 10)
    8. Dressing (scored as 0, 5, 10)
    9. Controlling bowels (scored as 0, 5, 10)
    10. Controlling bladder (scored as 0, 5, 10) The minimum value means with help and maximum independent

    Measured: Barthel Index data is collected at Baseline, V3 (+37 days), V5 (+26 weeks), V7 (+52 weeks), End of trial visit (EOT, +78 weeks) or Early discontinuation visit (EDV, on average 30 days), and Endpoint (18 months).

  8. National Institutes of Health Stroke Scale (NIHSS)

    The NIHSS is a systematic assessment tool that provides a quantitative measure of stroke-related neurologic deficits.

    The following questions will be asked:

    1a. Level of Consciousness (LOC) (scored as 0, 1, 2, 3)

    1b. LOC Questions (scored as 0, 1, 2)

    1c. LOC Commands (scored as 0, 1, 2) 2. Best Gaze (scored as 0, 1, 2) 3. Visual (scored as 0, 1, 2, 3) 4. Facial Palsy (scored as 0, 1, 2, 3) 5a. Motor Arm (Left Arm) (scored as 0, 1, 2, 3, 4) 5b. Motor Arm (Right Arm) (scored as 0, 1, 2, 3, 4) 6a. Motor Leg (Left Leg) (scored as 0, 1, 2, 3, 4) 6b. Motor Right (Right Leg) (scored as 0, 1, 2, 3, 4) 7. Limb Ataxia (scored as 0, 1, 2) 8. Sensory (scored as 0, 1, 2) 9. Best Language (scored as 0, 1, 2, 3) 10. Dysarthria (scored as 0, 1, 2) 11. Extinction and Inattention (formerly Neglect) (scored as 0, 1, 2) The sum of all 15 individual scores will provide the patient's total NIHSS score where 0 is "no stroke symptoms" and 42 is "severe stroke".

    Measured: National Institutes of Health Stroke Scale (NIHSS) data is collected at Baseline, V3 (+37 days), V5 (+26 weeks), V7 (+52 weeks), End of trial visit (EOT, +78 weeks) or Early discontinuation visit (EDV, on average 30 days), and Endpoint (18 months).

  9. Patient Health Questionnaire (PHQ-9)

    The PHQ-9 can be used for screening, diagnosing and measuring the severity of depression in stroke patients. The patient will rate on a scale from 0 (not at all) to 3 (nearly every day) how often each of the 9 symptoms occurred during the past 2 weeks. The individual scores from each item of the PHQ-9 will be added to calculate the total PHQ-9 score for each time of examination.

    Measured: Over 18 months follow-up period

  10. Overall Survival at 6, 12, and 18 Months After Randomization

    Overall survival (time to death relative to the date of randomization) will be analysed and presented by means of the Kaplan-Meier estimates (including censored data e.g. withdrawals) after 6 months (Day 182), 12 months (Day 365) and 18 months (Day 547) for the survival rates.

    Measured: Over 18 months follow-up period

  11. Treatment Emergent Adverse Events (TEAEs) Incl. Findings From Physical and Neurological Examinations

    Adverse events (AEs) not considered treatment-emergent according to this definition or with missing data will be medically reviewed during the data review meeting and will be considered treatment emergent if appropriate

    Measured: Over 18 months follow-up period

  12. Clinically Significant Haematology Abnormalities

    Based on haemoglobin, haematocrit, red blood cell count (RBC), white blood cell count (WBC), differential - neutrophils, eosinophils, lymphocytes, monocytes and basophils, and platelet count. All laboratory values will be classified as normal or abnormal according to the laboratories normal ranges and as clinically significant according to the assessment of the investigator. For these tests, approximately 12 mL of blood will be collected at each blood withdrawal.

    Measured: Over 18 months follow-up period

  13. Clinically Significant Biochemistry Abnormalities, Including eGFR (Estimated Glomerular Filtration Rate) and Coagulation

    The biochemistry analysis is based on sodium (will be monitored for signs of hyponatraemia), potassium, chloride, calcium, phosphate, blood urea nitrogen, aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH), alkaline phosphatase, creatine phosphokinase (CPK), creatinine, glucose, C-reactive protein, albumin, total protein, total cholesterol, low-density lipoproteincholesterol, high-density lipoprotein-cholesterol, triglycerides, and total bilirubin (bilirubin will be fractionated direct/indirect if elevated). eGFR will be estimated based on serum creatinine value using the according CKD-EPI formula using age, sex and race. Coagulation is based on international normalised ratio and activated partial thromboplastin time (aPTT). All laboratory values will be classified as normal or abnormal according to the laboratories normal ranges and as clinically significant according to the assessment of the investigator.

    Measured: Over 18 months follow-up period

  14. Clinically Significant Urinalysis Abnormalities

    The urinalysis is based on pH, specific gravity, protein, blood, glucose, ketones, bilirubin, urobilinogen (local dipstick). Microscopy and other appropriate tests (as needed) will be performed if dipstick indicates any significant abnormality. All laboratory values will be classified as normal or abnormal according to the laboratories normal ranges and as clinically significant according to the assessment of the investigator.

    Measured: Over 18 months follow-up period

  15. Clinically Significant Vital Sign Abnormalities: Blood Pressure

    The systolic and diastolic blood pressure (mmHg) were to be measured after the patient had rested for at least 5 minutes. Painful procedures, like drawing blood, had to be performed after vital signs measurements (not before). The analyses of variables for vital sign parameters will focus on the evaluation of the change from baseline to the scheduled time points after baseline. Descriptive statistics of the time course and of changes from baseline to each post-baseline time point will be presented by treatment group.

    Measured: Over 18 months follow-up period

  16. Clinically Significant Vital Sign Abnormalities: Heart Rate

    The Heart Rate (bpm) were to be measured after the patient had rested for at least 5 minutes. Painful procedures, like drawing blood, had to be performed after vital signs measurements (not before). The analyses of variables for vital sign parameters will focus on the evaluation of the change from baseline to the scheduled time points after baseline. Descriptive statistics of the time course and of changes from baseline to each post-baseline time point will be presented by treatment group.

    Measured: Over 18 months follow-up period

  17. Electrocardiogram (ECG)

    The ECG equipment is to be calibrated to 1 cm/mV and recording is to be done at 25 mm/sec and performed for a minimum of 10 sec. At V1a the investigator should examine the ECG for signs of cardiac disease that should exclude the patient from the trial. An assessment of normal or abnormal will be recorded and if the ECG abnormality is considered clinically significant, the abnormality will be documented in the electronic case report form (eCRF). If an ECG was done after primary stroke, the results should be used and the examination does not need to be repeated at V1a. After each recording of a simultaneous 12-lead resting ECG, a copy of the originally printed ECG records will be printed, assessed and filed by the investigator, in order to ensure that maintenance of the data will not be affected by thermolability of the paper.

    Measured: A standard 12-lead electrocardiogram (ECG) is performed at Baseline, V2 (+7 days), V3 (+37 days), Early discontinuation visit (if EDV performed before V3, on average 30 days).

  18. Suicidal Ideation and Behaviour, Assessed by PHQ-9 (Question 9)

    The individual scores from each item of the PHQ-9 will be added to calculate the total PHQ-9 score for each time of examination.Over the last 2 weeks, how often have you been bothered by any of the following problems?

    1. Little interest or pleasure in doing things
    2. Feeling down, depressed, or hopeless
    3. Trouble falling or staying asleep, or sleeping too much
    4. Feeling tired or having little energy
    5. Poor appetite or overeating
    6. Feeling bad about yourself - or that you are a failure or have let yourself or your family down
    7. Trouble concentrating on things, such as reading the newspaper or watching television
    8. Moving or speaking so slowly that other could have noticed. Or the opposite - being so fidgety or restless that you have been moving around a lot more than usual
    9. Thoughts that you would be better off dead or of hurting yourself in some way The individual scores from each item of the PHQ-9 will be added to calculate the total PHQ-9 score for each time of examination.

    Measured: The PHQ-9 will be collected at Baseline, V3 (+37 Days), V5 (+26 weeks), V7 (+52 weeks), End of trial visit (EOT, +78 weeks) or Early discontinuation visit (if EDV performed before V3, on average 30 days), and Endpoint (18 months).

  19. Number of Participants With and Without Seizures Based on Electroencephalogram (EEG)

    Routine EEG assessment (standard 10-20 set of electrodes, digital recording with 256 Hz sampling rate) for a minimum of 20 min will be performed at the discretion of the investigator. The EEG will be performed as exploratory analysis to support the development of a predictor for the development of post-stroke epilepsy and is therefore an optional assessment. All EEG analyses will be presented for the EEG analysis subset (all patients in the full analysis set with a baseline and a post-baseline EEG recording available). EEG parameters will be evaluated exploratively using descriptive statistics.

    For this outcome was decided that results would be possibly explored in an manuscript.

    Measured: Two recordings were provided: one carried out before in the initial phase of enrollment into the trial at V1a (< 96 hours) and the second one after termination of eslicarpazepine acetate intake (EOT, +78 weeks).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ESL 800 mg in people with Post Stroke Epilepsy, run by Bial - Portela C S.A. at 22 sites in 9 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 9 inclusion and 19 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 2 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in Germany, Austria, Italy, Israel, United Kingdom and 4 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 2 May 2025). 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?

Proportion of Patients Who Experience the First Unprovoked Seizures (US) Within the First 6 Months After Randomisation (Failure Rate) (time frame: First 6 months after randomisation). 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 NCT06597084.

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 2 May 2025.
