Lacosamide as first add-on or conversion monotherapy: A retrospective real-life study

Research output: Contribution to journalArticlepeer-review

Abstract

PURPOSE: Lacosamide (LCM), the R-enantiomer of 2-acetamido-N-benzyl-3-methoxypropionamide, is a newer approved antiseizure medication characterized by a novel pharmacodynamic and favorable pharmacokinetic profile that was approved as adjunctive treatment for adults with focal onset and focal to bilateral tonic-clonic seizures in 2008, and recently also for monotherapy. The aim of this study was to evaluate the effectiveness and tolerability of LCM as first add-on or conversion monotherapy in adult subjects with focal epilepsy.

METHODS: We retrospectively included all adult patients who received LCM as first add-on regimen or as substitution monotherapy at least 12 months before starting the chart review, with a historical baseline of 6 months prior to day of the first administration of LCM. The choice of treatment was made independently by the epilepstologists, according to routine clinical practice. Clinical data were obtained at 3, 6, and 12 months after subjects started LCM and then analyzed to assess retention rate, seizure freedom, and adverse events (AE).

RESULTS: A total of 101 patients (58 men) with a mean age of 44 years and a median epilepsy duration of 6.6 years (range 1-53) were included in the study. At 12 months 72 patients retained LCM, 54 (75%) of them were seizure free, 44 (81.5%) in monotherapy and 10 (18.5%) in add-on LCM treatment. Among all subjects, 31 (57.4%) were free from seizure under LCM monotherapy throughout the entire observation period. Thirty one out of 72 (43%) PwE who retained LCM at 12 months, were free from seizures throughout the entire observation period. The maintenance median dosage of LCM was 200 mg/day. Ten (10%) subjects reported mild to moderate AE, most commonly drowsiness and dizziness. No serious AE were documented.

CONCLUSIONS: This real-life study confirms that LCM is an effective and well tolerated treatment option as first add-on or conversion monotherapy for focal seizures.
