To report the efficacy and tolerability of lacosamide as an add-on treatment in patients with gliomas and uncontrolled seizures despite conventional antiepileptic drugs (AEDs).

A reduction ≥ 50% of seizures was observed in a proportion of patients with progressive disease on MRI. Age > 45 years (OR 0.11, 95% CI 0.02-0.63, p = 0.013) was a significant predictor of seizure freedom at 9 months on multivariate analysis. The study suggests that lacosamide, when added to any baseline AEDs, is effective in obtaining a high seizure reduction and seizure freedom regardless of the tumor activity and response to antineoplastic therapies.

Abstract

To report the efficacy and tolerability of lacosamide as an add-on treatment in patients with gliomas and uncontrolled seizures despite conventional antiepileptic drugs (AEDs). We conducted an observational study on 71 patients to describe patterns of response to lacosamide and the association between clinico-pathological factors and seizure control. We observed at 3, 6 and 9 months a seizure reduction ≥ 50% in 74.6, 76 and 86.2% of patients and a seizure freedom in 42.2, 43 and 50%, respectively. The median number of seizures in the 3 months before treatment was 13, and decreased to 3 between baseline and 6 months, and to 0.5 between 6 and 9 months. The best seizure response was observed at 3 months (62%). Sixty per cent of patients displayed the maximum seizure control with doses of lacosamide of 100-250 mg/day, while 21% needed doses up to 400 mg/day. Seizure reduction ≥ 50% and seizure freedom were higher in patients who received lacosamide as first add-on compared to those who received a later adjunctive therapy. A reduction ≥ 50% of seizures was observed in a proportion of patients with progressive disease on MRI. Age > 45 years (OR 0.11, 95% CI 0.02-0.63, p = 0.013) was a significant predictor of seizure freedom at 9 months on multivariate analysis. The study suggests that lacosamide, when added to any baseline AEDs, is effective in obtaining a high seizure reduction and seizure freedom regardless of the tumor activity and response to antineoplastic therapies.
