A Post-marketing Study Evaluating Eslicarbazepine Acetate (ESL) as Adjunctive Treatment in Partial-Onset Seizures (Study E2093-E044-404) (EPOS)

August 18, 2015 updated by: Eisai Inc.

An Open-label, Multi-centre, Multi-national Post-marketing Non-interventional Prospective Study Evaluating Retention Rate, Seizure Control and Tolerability of Eslicarbazepine Acetate (ESL) as Adjunctive Treatment to One Baseline Antiepileptic Drug in Adult Patients With Partial-Onset Seizures With or Without Secondary Generalisation

This was a Non-interventional Prospective Study. Centres enrolled adult patients with partial-onset seizures with or without secondary generalisation for whom the clinician had decided to initiate Eslicarbazepine Acetate (ESL) as an adjunctive therapy prior to the decision to take part in this study. Patients enrolled into the study were not sufficiently controlled with one drug licensed for the use as monotherapy in partial-onset seizures. Patients were seen at baseline and then during normal clinical visits at intervals. Patients in this study were assessed for efficacy and tolerability at baseline and then at least 3 and 6 months after the baseline.

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

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Normal clinical practice setting/ centre.

Description

Inclusion Criteria:

  • The decision to prescribe ESL was made by the physician before and independently of his/her decision to include the patient in the study
  • Patients treated with one drug licensed for monotherapy in partial onset seizures
  • Based on the physician's clinical judgment, the patient seizure activity was not controlled sufficiently with a current monotherapy and it was in the patient's best interest to be prescribed adjunctive ESL
  • Patient was prescribed ESL no longer than 2 weeks before the baseline
  • Treatment with ESL was to be commenced in line with the drug's license and Eslicarbazepine Acetate (ESL) Summary of Product Characteristics (SPC)
  • Aged 18 years or older
  • Signed written informed consent

Exclusion Criteria:

  • Patients that had started ESL outside the approved SPC at enrolment
  • Simultaneous participation in an interventional clinical trial

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Eslicarbazepine Acetate tablets
Drug: Eslicarbazepine Acetate tablets
The Eslicarbazepine Acetate (ESL) Summary of Product Characteristics (SPC) recommended a starting dose of 400 mg once-daily (QD) which was increased to 800 mg QD after one or two weeks. Based on individual response, the dose was increased to 1200 mg QD. Treatment decisions were made by clinicians in agreement with the participant, and were independent of participation in the study.

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
Time Frame
Retention Rate of Eslicarbazepine Acetate (ESL) After 6 months from Baseline
Time Frame: 6 months
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
Change in Overall Seizure Frequency after 3 and 6 months from Baseline
Time Frame: Baseline, 3 months and 6 months
Change in overall seizure frequency calculated as absolute and percent changes after 3 and 6 months from baseline compared to the seizure frequency 3 months before introduction of ESL.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
