【 摘 要 】

BackgroundProspective observations on the effectiveness, safety, tolerance, and influence of comorbidity of add-on lacosamide (LCM) therapy are still lacking, especially for domestic generic LCM in China.ObjectiveIn this multicenter real-world study, we aimed to evaluate lacosamide (LCM) as the first add-on therapy in adult Chinese patients with focal epilepsy that had initially been treated with monotherapy.MethodsA cohort of consecutive focal epilepsy patients aged over 16 years were enrolled and followed at the multi-epilepsy centers in China. LCM was prescribed as the first add-on therapy. The main outcome measures included seizure frequency and response rate. Data on seizure-free rate, retention rate, scales of depression and anxiety, and adverse events were also collected as additional outcome measures.ResultsA total number of 107 adult subjects (60 men, 56.07%) were enrolled. The mean age was 37.16 ± 15.01 years, and the mean age at seizure onset was 312.35 ± 199.97 months. After the LCM add-on therapy, the ≥50% response rates were 76.19, 81.73, 94.12, and 95.79% at the visit at 4 weeks (visit 2), 8 weeks (visit 3), 16 weeks (visit 4), and 24 weeks (visit 5), respectively, compared to the baseline (visit 1). A total of 34 patients (31.78%) had no seizures during the whole follow-up period. The posttreatment emotional performance of the 97 subjects, defined as generalized anxiety disorder (GAD) and Neurological Disorders Depression Inventory (NDDI) scores, was significantly better than the baseline one. Only one patient suffered from mild dizziness.ConclusionLCM as the first add-on therapy in adult focal epilepsy in China was effective and safe. Further prospective studies with long-term follow-up periods are needed to confirm our present findings.Clinical trial registrationhttp://www.chictr.org.cn, ChiCTR2100042485.
