ABSTRACT

OBJECTIVE:

To evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of lacosamide (LCM) (up to 12 mg/kg/day or 600 mg/day) as adjunctive therapy in pediatric patients with epilepsy syndromes associated with generalized seizures.

METHODS:

Phase 2, multicenter, open-label exploratory trial (SP0966; NCT01969851; 2012-001446-18) of oral LCM for epilepsy syndromes associated with generalized seizures in pediatric patients ≥1 month to <18 years of age taking one to three concomitant antiseizure medications. The trial comprised a 6-week prospective baseline period, 6-week flexible titration period, and 12-week maintenance period.

RESULTS:

Fifty-five patients (mean age 9.2 years; 56.4% male) took at least one dose of LCM and had at least one post-baseline efficacy-related assessment. The median treatment duration was 127.0 days. There were no clinically significant mean or median changes or worsening from baseline to end of the titration period in the count of generalized spike-wave discharges per interpretable hour on 24-h ambulatory electroencephalogram recordings, or from baseline to the maintenance period in mean and median days with any generalized or focal to bilateral tonic-clonic seizures per 28 days. Treatment-emergent adverse events (TEAEs) were reported by 49 patients (89.1%), and three patients (5.5%) discontinued due to TEAEs. The median change and median percentage change in days with any generalized or focal to bilateral tonic-clonic seizures per 28 days from baseline to the maintenance period were both 0. Trends toward improvement (decrease) were observed in median change and median percentage change in days with each individual seizure type (absence, myoclonic, clonic, tonic, tonic-clonic, atonic, and focal to bilateral tonic-clonic) per 28 days.

SIGNIFICANCE:

Safety findings were consistent with the known safety profile of LCM and were as expected for the pediatric population. There was no worsening of generalized seizures with LCM. Limitations include the inability to correlate spike and wave data with clinical outcomes, and the lack of similar studies against which the results can be compared.
