ZEBinix® Retention Rate in Epilepsy in Elderly Patients (ZEBRE)

January 7, 2020 updated by: Centre Hospitalier Saint Joseph Saint Luc de Lyon

ZEBinix Retention Rate in Epilepsy in Elderly Patients

The incidence of provoked and unprovoked seizures is known to increase with advancing age. Eslicarbazepine acetate (ESL) is one of the third generation of antiepileptic drugs (AEDs) that have been developed in the last ten years with a favorable safety profile. ESL is approved in Europe and the USA as adjunctive or monotherapy in adults with partial-onset seizures. Nevertheless, retrospective data in monotherapy condition in the elderly epileptic population are sparse. The aim of the ZEBRE study is to evaluate the efficacy and the safety of ESL in elderly epileptic patients (> 65 years). The completion of this study will provide crucial information on the most appropriate ESL treatment for elderly patients suffering from partial seizures.

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

65 years and older (Older Adult)

Sampling Method

Probability Sample

Study Population

Elderly patients ≥ 65 years that undergo at least one seizure in the last three months and with no history of ESL tratment or history of epilepsy status will be screened. ESL will be initiated by the investigator in patients with refractory partial seizures with or without generalized seizures or with PGTC seizures as a first line monotherapy or adjunctive therapy. In case of inefficacy or toxicity the dose of ESL will be gradually titrated up to 1 600 mg or titrated down to 600 mg, respectively.

Description

Inclusion Criteria:

  1. Age ≥ 65 years
  2. Ability of patient/legal representative to understand the study and to give his/her non-opposition (at the investigator's discretion)
  3. Epilepsy with refractory partial-onset seizures with or without secondary generalization confirmed or with primary generalized tonic-clonic (PGTC) seizures
  4. At least one seizure in the last three months
  5. Treatment for partial-onset seizures with ESL as a first line monotherapy or with an adjunctive therapy

Exclusion Criteria:

  1. History of ESL treatment
  2. History of status epilepticus, seizures occurring in cluster, pseudo-seizures
  3. History of severe hepatic impairment (aspartate aminotransferase (AST) and alanine aminotransferase (ALT) > 2 times ULN, gamma-glutamyltranspeptidase (GGT) > 5 times ULN)
  4. History of severe renal impairment (clearance CLCR <30ml/min)
  5. History of hypersensitivity to other carboxamide derivatives (e.g. carbamazepine, oxcarbazepine)
  6. History of severe hyponatremia (< 120 mmol/L)
  7. Second or third degree atrioventricular block
  8. More than one other antiepileptic drug

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
Retention rate of ESL treatment as assessed by the number of patients that are still included in the study.
Time Frame: at the end of the study treatment, at 6 months
The retention rate is representative of the effect of ESL since ESL will be pursued only if ESL has a sufficient efficacy without adverse effect. To evaluate the effect of ESL in elderly patients with partial-onset seizures, the retention rate will be measured after 6 months of treatment with ESL.
at the end of the study treatment, at 6 months

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
Quality of life of patients as assessed by QOLIE-10 questionnaire
Time Frame: at each visits required by the study (baseline, 3 months and 6 months)
QOLIE-10 (quality of life in epilepsy) is a quality of life questionnaire for adults with epilepsy. There are 10 questions about health and daily activities. All positive responses are lower numbers and all negative responses are higher numbers.
at each visits required by the study (baseline, 3 months and 6 months)
Quality of life of patients as assessed by QoL-AD questionnaire
Time Frame: at each visits required by the study (baseline, 3 months and 6 months)
Some patients with epilepsy also have cognitive decline. QOL-AD (quality of life in Alzheimer'disease) measure quality of life in people with severe cognitive decline. A total score of 13-52, with higher scores indicating better QoL.
at each visits required by the study (baseline, 3 months and 6 months)
Quality of life of patients as assessed by NDDIE questionnaire
Time Frame: at each visits required by the study (baseline, 3 months and 6 months)
NDDI-E (neurological disorder depression inventory for epilepsy) is used for detecting major depressive disorder; a total score above 15 should raise the suspicion of a major depressive episode.
at each visits required by the study (baseline, 3 months and 6 months)
Incidence of treatment- adverse events as assessed by adverse events reports
Time Frame: through study completion, an average of 6 months
Number of patients with treatment-related adverse events will be reported to the pharmacovigilance department. Number of participants with abnormal laboratory values and/or adverse events that are related to treatment will be assessed.
through study completion, an average of 6 months
Incidence of seizures as assessed by the occurrence of seizures
Time Frame: at each visits required by the study (baseline, 3 months and 6 months)
The number and the type of seizures or the number of seizure free in elderly patients will be reported
at each visits required by the study (baseline, 3 months and 6 months)
Observance of the treatment as recorded by the control of the drug administration
Time Frame: through study completion, an average of 6 months
The treatment delivery by the pharmacy be performed to assess the compliance of the treatment.
through study completion, an average of 6 months
