Purpose: The aim of this study was to evaluate the efficacy and tolerability of lacosamide (LCM) both as add-on therapy and monotherapy in patients with temporal lobe epilepsy (TLE) based on an observational, prospective, multicenter study. Methods: We enrolled 100 patients (mean age: 43.4 +/- 12.53 years, 57 females) with nonlesional TLE and TLE with hippocampal sclerosis (HS) that did not respond to the first drug and who were referred to epilepsy centers of the University of Catanzaro, University of Palermo, IRCSS Neuromed of Pozzilli, and Otto-von-Guericke University of Magdeburg. In this open-label, multicenter trial, patients were initiated on oral LCM as add-on therapy to first AED monotherapy or as a later add-on to two concomitant AEDs. Seizure frequency changes and adverse events were recorded for at least six months after LCM was added. Results: Fourteen patients dropped out because of positive MRI findings other than HS. Patients received LCM at 200-400 mg/day. Fifty-eight out of these 86 patients with seizures that were previously drug-resistant had reduced seizure frequency after introduction of LCM. Forty-five out of 86 patients were classified as responders (12 were seizure-free, 33 achieved a reduction >50%). Interestingly, five patients out of 86 achieved seizure freedom for at least one year and progressively switched to monotherapy with LCM, and all five remained seizure-free at follow-up (6-48 months). Conclusions: Our results may suggest that LCM at doses of 200 to 400 mg/day reduces seizure frequency in adults with TLE regardless of the presence of HS, and that it may be considered as a first add-on treatment for patients with pharmacoresistant TLE.

Abstract

Purpose: The aim of this study was to evaluate the efficacy and tolerability of lacosamide (LCM) both as add-on therapy and monotherapy in patients with temporal lobe epilepsy (TLE) based on an observational, prospective, multicenter study. Methods: We enrolled 100 patients (mean age: 43.4 +/- 12.53 years, 57 females) with nonlesional TLE and TLE with hippocampal sclerosis (HS) that did not respond to the first drug and who were referred to epilepsy centers of the University of Catanzaro, University of Palermo, IRCSS Neuromed of Pozzilli, and Otto-von-Guericke University of Magdeburg. In this open-label, multicenter trial, patients were initiated on oral LCM as add-on therapy to first AED monotherapy or as a later add-on to two concomitant AEDs. Seizure frequency changes and adverse events were recorded for at least six months after LCM was added. Results: Fourteen patients dropped out because of positive MRI findings other than HS. Patients received LCM at 200-400 mg/day. Fifty-eight out of these 86 patients with seizures that were previously drug-resistant had reduced seizure frequency after introduction of LCM. Forty-five out of 86 patients were classified as responders (12 were seizure-free, 33 achieved a reduction >50%). Interestingly, five patients out of 86 achieved seizure freedom for at least one year and progressively switched to monotherapy with LCM, and all five remained seizure-free at follow-up (6-48 months). Conclusions: Our results may suggest that LCM at doses of 200 to 400 mg/day reduces seizure frequency in adults with TLE regardless of the presence of HS, and that it may be considered as a first add-on treatment for patients with pharmacoresistant TLE.
