Study summary

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.

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

Groups and cohorts

  • Eslicarbazepine Acetate tablets

    Drug: Eslicarbazepine Acetate tablets

Interventions

  • DrugEslicarbazepine 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 researchers measure

Primary outcomes

  1. Retention Rate of Eslicarbazepine Acetate (ESL) After 6 months from Baseline

    Time frame: 6 months

Secondary outcomes

  1. Change in Overall Seizure Frequency after 3 and 6 months from Baseline

    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.

    Time frame: Baseline, 3 months and 6 months
