PURPOSE: Temporal lobe epilepsy (TLE) is often associated with drug-resistant seizures. We evaluated the efficacy and tolerability of lacosamide (LCM) versus controlled-release carbamazepine (CBZ-CR) monotherapy in adults with newly diagnosed TLE.
METHODS: Exploratory post hoc analysis of patients with temporal focus of localization (indicated as the only localization focus) in a double-blind, noninferiority, phase 3 trial (SP0993; NCT01243177) in patients aged ≥ 16 years with newly diagnosed epilepsy randomized 1:1 to LCM or CBZ-CR monotherapy.
RESULTS: Of 886 treated patients in this trial, temporal lobe focus of localization (TLE) was reported as the single focus for 287 (32.4%) patients (LCM 134, CBZ-CR 153). A similar proportion of patients with TLE on LCM (82 [61.2%]) and CBZ-CR (99 [64.7%]) completed the trial. Kaplan-Meier estimates for 6- and 12-month seizure freedom at the last evaluated dose level (stratified by number of seizures in the 3 months before screening [≤2 or >2 seizures]) were similar with LCM and CBZ-CR (6 months overall: 88.7% and 89.7%; 12 months overall: 78.3% and 81.7%). Treatment-emergent adverse events (TEAEs) were reported by fewer patients on LCM (73.9%) than CBZ-CR (81.0%). Drug-related TEAEs (assessed by the investigator) were reported in 41.8% of patients on LCM and 52.3% of patients on CBZ-CR; 11.2% of patients on LCM and 15.0% on CBZ-CR discontinued due to TEAEs.
CONCLUSION: Lacosamide was efficacious and generally well tolerated as monotherapy in patients with TLE with efficacy outcomes comparable with CBZ-CR, and fewer patients on LCM reported any TEAEs, drug-related TEAEs, or discontinued due to TEAEs.
