Long-term safety and tolerability of lacosamide monotherapy in patients with epilepsy: Results from a multicenter, open-label trial

• The primary objective of this trial (SP1042; NCT02582866) was to assess long-term safety and tolerability of lacosamide monotherapy (200-600 mg/day) in adults with focal (partial-onset) seizures or generalized tonic-clonic seizures (without clear focal origin). This Phase III, long-term, open-label, multicenter, follow-up trial enrolled patients with epilepsy who were taking lacosamide in, and completed, the previous double-blind trial (SP0994; NCT01465997). Primary safety outcomes were treatment-emergent adverse events (TEAEs), discontinuations due to TEAEs, and serious TEAEs. One hundred and six patients were enrolled and received lacosamide: 84 (79.2%) completed the trial and 22 (20.8%) discontinued. The median duration of exposure was 854.0 days, with a median modal dose of 200 mg/day. Ninety-six (90.6%), 64 (60.4%), and 44 (41.5%) patients had >= 12, >= 24, and >= 36 months of lacosamide exposure, respectively. At least one TEAE was reported by 61 (57.5%) patients. The most common (>= 4%) TEAEs were headache (10 [9.4%]), nasopharyngitis (eight [7.5%]), and back pain (five [4.7%]). One (0.9%) patient discontinued due to a TEAE (sudden unexpected death in epilepsy; not considered drug-related), 14 (13.2%) patients reported serious TEAEs, and seven (6.6%) patients reported TEAEs that were considered drug-related. Overall, long-term lacosamide monotherapy was generally well tolerated up to 600 mg/day, with no new safety signals identified.
