Abstract
BACKGROUND
Due to inadequate seizure control achieved with antiepileptic drug (AED) monotherapy and the considerable side effects at high required doses, patients with partial-onset seizures (POS) often require AED combination therapy. Eslicarbazepine acetate (ESL) is licensed as an add-on therapy for POS and has a favorable tolerability profile.
OBJECTIVES
To investigate retention, utilization, reported efficacy, safety and tolerability as well as effects on health-related quality of life using ESL as an add-on treatment to an established monotherapy in a real-world adult population with POS in Germany.
PATIENTS AND METHODS
A subgroup analysis was performed on the data derived from the German study sites that had participated in an international, non-interventional, open-label study conducted in eight European countries (eslicarbazepine acetate in partial-onset seizures, EPOS). Adult patients with POS whose physician had decided to prescribe add-on treatment with ESL to an established monotherapy were followed over a total period of approximately six months (three visits: baseline and after periods of approximately three and six months). Data collection included patient retention, reported efficacy, safety and tolerability as well as quality of life (QOLIE-10).
RESULTS AND DISCUSSION
The subgroup analysis included 104 patients which had been enrolled at 38 German study sites. After 6 months, retention of ESL add-on therapy was 86.5 %, with 44.7 % of patients reporting seizure freedom over the 3 months prior to this visit. The overall tolerability of ESL add-on therapy was favorable: 32 adverse events (AE) were reported in 20 patients (19.2 %), while only two events in two patients were considered serious. No new safety signals were detected.
