Long-term efficacy, safety, and tolerability, including behavior and executive functioning, during adjunctive lacosamide treatment in pediatric patients with uncontrolled epilepsy. Epilepsy Behav 2024; 159:109989. [PMID: 39216464 DOI: 10.1016/j.yebeh.2024.109989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Revised: 08/06/2024] [Accepted: 08/06/2024] [Indexed: 09/04/2024]
Abstract
OBJECTIVES To evaluate long-term efficacy, safety, and tolerability, including behavior and executive functioning, during adjunctive lacosamide (LCM) treatment in pediatric patients (≥1 month to <18 years of age) with focal-onset or generalized seizures enrolled in 2 open-label, long-term follow-up trials. METHODS Two open-label extension trials (SP848: NCT00938912; EP0034: NCT01964560) were conducted in pediatric patients who had participated in previous trials of adjunctive LCM (SP0847/NCT00938431; SP0966/NCT01969851; EP0060/NCT02710890; SP0967/NCT02477839; SP0969/NCT01921205); SP848 also directly enrolled eligible pediatric patients who had not previously participated in a clinical trial of LCM. Outcomes included retention, efficacy, and safety/tolerability. Patient improvement was assessed with Clinician's and Caregiver's Global Impression of Change scale. Behavior and emotional function was assessed with Achenbach Child Behavior Checklist (CBCL) and executive functioning was assessed with Behavior Rating Inventory of Executive Function® (BRIEF). RESULTS The pooled dataset from both trials included 905 patients (851 in the focal-onset seizure population and 47 in the generalized seizure population). In the overall population, Kaplan-Meier-estimated 1-year retention was 80 %. From baseline to the end of the treatment period, patients in the focal-onset seizure population had a median percent reduction in focal-onset seizure frequency per 28 days of 60.4 %, 55.4 % of patients were 50 % responders, and 40.8 % of patients were 75 % responders. In patients with ≥12 months of LCM treatment, ≥12 month seizure freedom during the LCM treatment period was achieved by 29.9 % of patients in the focal-onset seizure population (median duration of first ≥12-month seizure-free interval: 641 days) and 24.4 % of patients in the generalized seizure population (median duration of first ≥12-month seizure-free interval: 665 days). Improvement during LCM treatment was reported in >75 % of patients by both physicians and caregivers. Treatment-emergent adverse events (TEAEs) were reported by 749 (82.8 %) patients, most commonly pyrexia (18.9 %), upper respiratory tract infection (18.6 %), nasopharyngitis (16.2 %), vomiting (15.7 %), and somnolence (11.8 %). The most common drug-related TEAEs were somnolence (8.5 %), dizziness (7.6 %), and vomiting (5.4 %). Behavioral and emotional function was generally stable in patients 1.5-5 years of age and slightly improved in patients ≥6 years of age, and executive functioning was stable in patients <5 years of age and generally slightly improved in patients 5-18 years of age. CONCLUSIONS In this analysis of a large patient pool from 2 open-label trials, long-term adjunctive LCM was efficacious and generally well tolerated in children with epilepsy and focal-onset or generalized seizures. Behavior and executive functioning were generally stable without observable worsening during long-term adjunctive LCM treatment.

Seizure 2024; 118:71-79. [PMID: 38643678 DOI: 10.1016/j.seizure.2024.04.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 03/25/2024] [Accepted: 04/09/2024] [Indexed: 04/23/2024] Open
Abstract
BACKGROUND Lacosamide (LCM) has shown promising efficacy and safety outcomes in clinical trials. However, the evidence is limited among pediatric patients especially under four years in real-world. The study investigated the treatment outcomes and safety of LCM in patients under four years based on the data of the epilepsy registry of Children in China. METHODS A prospective cohort study was conducted among patients under 4 years who newly received LCM as monotherapy or adjunctive therapy. The treatment outcomes were measured by retention rate of LCM, 50 % response rates and seizure-free rates during follow-up. The retention rate of LCM was assessed using the Kaplan-Meier survival model. Adverse events were reported as a percentage of all participants. RESULTS Of 109 participants (mean follow-up: 18.6 months), 59 received LCM as monotherapy and 50 as adjunctive therapy. Sixty patients had focal epilepsy, 44 had generalized epilepsy and 5 had combined generalized and focal epilepsy. 70 % of patients in the monotherapy group and 41 % in the adjunctive therapy group remained on LCM treatment without additional treatments for at least one year. In patients with monotherapy, 50 % response rate and seizure-free rate were 75 % and 56 % at 12 months, respectively. In adjunctive therapy group, these rates were 51 % and 36 %, respectively. Lower baseline seizure frequency in both treatment groups (monotherapy: p < 0.001; adjunctive therapy: p = 0.02) and younger age groups within the monotherapy group (P = 0.04) correlated with a higher LCM retention rate. Adverse events were reported by 15 patients (13.8 %), with somnolence being the most common (7 of 15 patients). CONCLUSION With a comprehensive information and high-quality of data, the study demonstrates the effective treatment outcome and safety of LCM. The study adds reliable evidence to exiting real-word evidence of LCM in the specific age group of patients with epilepsy to fill the evidence gap.

Long-term effectiveness and safety of lacosamide as adjunctive therapy in children and adolescents with refractory epilepsy: a real-world study. BMC Pediatr 2023; 23:249. [PMID: 37210552 DOI: 10.1186/s12887-023-04039-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 04/26/2023] [Indexed: 05/22/2023] Open
Abstract
PURPOSE The effectiveness and tolerability of lacosamide (LCM) among Chinese children and adolescents with refractory epilepsy has not yet been established. Therefore, the objective of this study was to assess the effectiveness and tolerability of LCM among children and adolescents with refractory epilepsy in Xinjiang, Northwest China. METHODS Effectiveness was assessed by measuring changes in seizure frequency at 3, 6 and 12 months compared with baseline. Patients that achieved ≥ 50% reduction in the frequency of all seizures per month, relative to baseline, were considered to be responders. RESULTS 105 children and adolescents with refractory epilepsy were enrolled in the study. The responder rates were 47.6%, 39.2%, and 31.9%, respectively at 3, 6, and 12 months. Seizure freedom rates were 32.4%, 28.9%, and 23.6% at 3, 6, and 12 months, respectively. The retention rates at 3, 6, and 12 months were 92.4%, 78.1%, and 69.5%, respectively. The maintenance dose of LCM within the responder group (8.2 ± 4.5 mg·kg- 1·d- 1) was significantly higher compared to the non-responder group (7.3 ± 2.3 mg·kg- 1·d- 1) (p < 0.05). At first follow-up, 44 patients (41.9%) reported experiencing at least one treatment-emergent adverse events. CONCLUSION This real-world study of children and adolescents validated that LCM was both an effective and well-tolerated treatment option for the treatment of refractory epilepsy.

Abstract
OBJECTIVE To evaluate the efficacy and retention rate of lacosamide (LCM) over 36 months as a treatment for children and adolescents with focal and generalized epilepsy based on a retrospective study. METHODS All patients prescribed LCM as monotherapy and add-on therapy between October 2016 and September 2019 at Jichi Children's Medical Center Tochigi were included in the study. The response rate, retention rate, and adverse effects were calculated. RESULTS A total of 126 (female, n = 73) patients of 1.3 to 34.9 years old (median age: 12.8 years; mean ± SD 13.2 ± 6.6 years) received LCM as monotherapy or add-on treatment for focal, generalized, and combined focal and generalized epilepsy. The response rate was 40.5% at 3 months, 40.5% at 6 months, 38.1% at 9 months, 35.7% at 12 months, 25.9% at 24 months, and 29.4% at 36 months. For 34 patients who were observable for 36 months, the retention rate was 70.6% at 3 months, but then gradually declined to 34.8% at 36 months. According to the number of concomitant anti-seizure medications (ASMs), the retention rate was higher in patients receiving <3 ASMs than in those receiving ≥3 ASMs at all observation points. The most common adverse effects were somnolence in 21 patients (16.7%) and dizziness in 5 patients (39.7%). CONCLUSION Our response rate was lower and our retention rate was higher in comparison to a previous study that observed patients over 36 months. Further prospective studies in children are required to confirm the response rate and retention rate in patients treated with LCM over 36 months.

Abstract
PURPOSE To evaluate the efficacy and tolerability of adjunctive lacosamide (LCM) in patients with focal-onset seizures, with or without combined secondarily generalized seizures. METHODS 106 patients aged ≥ 16 years were recruited consecutively in this single-center prospective observational study. All patients received LCM as an add-on treatment on the basis of clinical judgement. Seizure frequency, adverse events (AEs) and retention rates were obtained at 3 and 6 months after LCM introduction. RESULT The overall response rates were 53.3 and 70.4% after 3 and 6 months, respectively, and the freedom of seizures at the same points was reached at 19 and 26.5%. The retention rates were 99.1% at the 3-month follow-up and 93.3% at the 6-month follow-up. The overall incidence of adverse events was 35.8%. The leading AEs were dizziness (16.98%) and sedation (6.6%). CONCLUSIONS Our study confirmed the efficacy and tolerability of adjunctive LCM in Chinese patients in real-life conditions. Based on our treatment experience, a universal maintenance dose of LCM would be needed in Chinese patients.

Abstract
OBJECTIVE Lacosamide (LCM), is a third-generation antiseizure medicine, with limited clinical evidence for use in pediatric populations. We aimed to evaluate evidence for the efficacy and safety of LCM in pediatric patients with epilepsy. METHODS A systematic review was performed using literature published from inception to February 2022 identified in MEDLINE, Embase, Cochrane Library, and four Chinese databases. Efficacy and safety outcome data were collected, and a meta-analysis was performed. RESULT Twenty-one studies involving 1230 pediatric patients were included. The median percent reduction in seizure frequency per 28 days from baseline to maintenance was 33.1% (95% confidence interval [CI] 22.7%, 43.5%). After 6 months of treatment, the 50%, 75%, and 100% responder rates were 53.3% (95% CI 40.7%, 65.9%), 28.3% (95% CI 20.8%, 35.8%), and 20.4% (95% CI 12.6%, 28.2%), respectively. After 12 months of treatment, the 50%, 75%, and 100% responder rates were 42.0% (95% CI 29.5%, 54.5%), 19.5% (95% CI 11.1%, 27.8%), and 15.2% (95% CI 6.6%, 23.8%), respectively. The most common adverse events (AEs) were drowsiness (15.0%), dizziness (9.9%), and somnolence (8.3%). CONCLUSION Lacosamide is generally effective and well tolerated to use in children with epilepsy. However, further research with high-quality data and long-term follow-up of LCM use in pediatric populations is needed.

Clinical impact of the dose and blood concentration of lacosamide in Japanese pediatric patients with epilepsy: A cohort study. Epilepsy Behav 2022; 129:108614. [PMID: 35203014 DOI: 10.1016/j.yebeh.2022.108614] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 02/05/2022] [Accepted: 02/05/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE The relationship between treatment efficacy/tolerability and the dose/blood concentration of lacosamide (LCM) was investigated in a clinical cohort of Japanese pediatric patients with epilepsy. METHODS This retrospective analysis reviewed the medical records of patients treated with LCM for >6 months at the Department of Pediatrics, Hiroshima University Hospital, from September 2017 to January 2021. The collected data included age, sex, epilepsy type, seizure type, seizure frequency before and after treatment initiation, adverse events leading to LCM discontinuation, dose at any evaluation point, serum concentration, and concomitant antiepileptic drugs (AEDs). RESULTS The study included 51 patients (31 male patients) between the ages of 2 and 19 years. All patients were Japanese. Epilepsy was classified as focal in 44 patients, generalized in six patients, and combined generalized and focal in one patient. The 50% responder rate for LCM treatment was 56.9%. Seven patients experienced complete seizure control (absence of seizures for 6 months before the follow-up visit). A relationship between dose and blood concentration was identified. Although the blood LCM concentration was higher in the responders than in the nonresponders (7.86 vs. 6.16 μg/mL; p = 0.028), there was no significant difference in dose between the two groups. Lacosamide showed efficacy at a dose >5 mg/kg/day in more than half of the 50% responders. The treatment-emergent adverse events (TEAEs) included seizure aggravation in five patients, irritability in two patients, and somnolence and drug eruption in one patient each. In six patients with TEAEs, the TEAEs developed within 1 month after treatment initiation and led to LCM discontinuation. CONCLUSION In Japanese pediatric patients with epilepsy, LCM treatment is effective, particularly at higher doses. The blood concentration may be related more to efficacy than to dose. Lacosamide is generally well-tolerated by pediatric patients, and should be used at the maximum tolerable dose (needed to be gradually increased) in patients with otherwise insufficient seizure control. As TEAEs leading to discontinue treatment likely occur in early phase, it is needed to monitor patients carefully if TEAEs would happen in that phase.

Lacosamide effectiveness and tolerability in patients with drug-resistant epilepsy and severe disability under polytherapy: Therapy optimization as emerging from an observational study. Epilepsy Behav 2022; 128:108598. [PMID: 35151192 DOI: 10.1016/j.yebeh.2022.108598] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 01/17/2022] [Accepted: 01/24/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVE We explored the efficacy and safety of lacosamide combined with inhibitors of fast-inactivated sodium channels or with other antiepileptic drugs, in patients with drug refractory focal epilepsy associated with intellectual or psychiatric disability. METHODS Observational study of lacosamide including the monitoring of lacosamide trough plasma levels and of electroencephalograms. RESULTS We followed up 44 patients from the start of lacosamide therapy for up to 3 years, with a clinical, electroencephalogram (EEG), and pharmacological follow-up. Median patients' age was 32.7 years, median age at epilepsy onset was 3.5 years. Intellectual disability was severe in 55.4% of the cohort and drug refractoriness was diagnosed in 88.6% of patients, who had predominantly focal seizures (80%). The severity of their epilepsy was suggested by the use of combined therapies with non-sodium blockers and sodium blockers in 75% of patients. Lacosamide was added to previous therapies and up-titrated to a median of 300 mg/d. Lacosamide add-on led to simplification of the previous drug regimen with a dose reduction in 87.9% of users of sodium blockers and in 66.7% of users of non-sodium blockers, and to withdrawal of previously administered sodium blockers in 48.5% users and non-sodium blockers in 47.6% users. Lacosamide was prescribed at lower doses in the presence of oxcarbazepine (p = 0.029), lamotrigine (p = 0.015), and topiramate (p < 0.001). Mean lacosamide plasma levels were 6.0 ± 2.4 mg/L; they were in linear correlation with the administered dose (R2 = 0.38, p < 0.001) and were influenced by the association with lamotrigine (p = 0.008), zonisamide (p = 0.012), and clobazam (p = 0.028). Lacosamide combination regimens led to an average reduction of 42% in baseline seizure frequency, with 50% patients reporting ≥50% seizure frequency reduction. Efficacy was directly correlated with lacosamide dose (R2 = 0.47, p < 0.001, B = 0.53) and trough plasma levels (R2 = 0.31, p < 0.001, B = 0.16). Electroencephalogram profiles were improved in 40.9% of patients and EEG improvement was not significantly correlated with seizure frequency reduction. Lacosamide safety was good, with 37 adverse reactions in 30 patients, of which 50% were attributed to lacosamide and led to lacosamide withdrawal in 18% of cases. The retention rate of lacosamide was of 88.6% at 1 year, 86.4% at 2 years, and 72.7% after three years. The severity of intellectual disability was directly correlated with increased possibility of lacosamide retention (OR = 0.46 per severity tier, p = 0.016). CONCLUSION Lacosamide add-on allowed dose reduction of previous therapies and reduced the frequency of seizures, showing good tolerability even at high doses, without exceeding reference plasma levels.

Front Pediatr 2022; 10:949783. [PMID: 36160782 PMCID: PMC9490115 DOI: 10.3389/fped.2022.949783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Accepted: 08/19/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Lacosamide (LCM) is a newer anti-seizure medication (ASM) that was approved in China in 2018, but its real-world clinical data and plasma concentrations in Chinese children with epilepsy are very limited. Of note, the reference range for routine LCM therapeutic drug monitoring is still unknown. The purpose of this study was to investigate the efficacy and safety of LCM as a monotherapy or an adjunctive treatment with other ASMs and to evaluate the potential factors affecting its efficacy and variable LCM plasma concentrations in Chinese children with epilepsy. METHODS Children with epilepsy (<18 years) with routine plasma LCM monitoring from March 2019 to December 2021 at the Department of Pharmacy, Children's Hospital of Nanjing Medical University were retrospectively collected. Clinical data were obtained from the hospital information system. RESULTS 76 pediatric patients (52 males) were finally enrolled. Mean age was 7.9 years (1.3-17.3 years) with a mean dose of LCM 6.3 mg/kg/day (2.0-11.3 mg/kg/day). The TDM data as a whole showed that the median plasma trough concentration (C 0) was 3.42 μg/mL (1.25-8.31 μg/mL). A 6-month LCM add-on therapy produced 70% of patients achieving ≥50% seizure frequency reductions, and the number was 81% for the one-year follow-up findings. Interestingly, more patients who took LCM monotherapy achieved seizure freedom over the same periods of follow-up observations. Under maintenance dosages, approximately 92.1% of the C 0 values were 2.0-7.0 μg/mL. The plasma-C 0-to-daily dose (C 0/Dose) ratio was significantly associated with age and body weight (BW). The C 0/Dose ratio in patients aged 1- ≤ 6 and 6- ≤ 12 years was significantly higher by 81% and 29% than those aged 12- ≤ 18 years, respectively. The C 0/Dose ratio in patients with a BW of ≥40 kg was 1.7-fold lower than in patients with a BW of ≤ 20 kg. In addition, complex LCM-ASMs interactions were observed. Oxcarbazepine significantly decreased the C 0/Dose ratio of LCM by 28%. CONCLUSION This retrospective study confirmed the effectiveness and tolerability of the LCM treatment used alone or with other ASMs in children with focal epilepsy. Children with higher BW and older age have lower C 0/Dose ratio. Complex drug interactions between LCM and other concomitant ASMs were revealed. Notably, based on the data in our hands, the reference range, i.e., 2.0-7.0 μg/mL, for routine LCM monitoring may be feasible. The real-world evidence of this study supports LCM as a promising option in children with focal epilepsy.

Abstract
Background: As a third-generation antiseizure medication (ASM), lacosamide (LCM) is recommended worldwide for patients with epilepsy. We aimed to provide more conclusive evidence for the safety and tolerability of LCM in patients with epilepsy. Methods: A systematic search was performed on MEDLINE, Embase, Cochrane Library, CBM, CNKI, IDB, VIP Database, and Wanfang Database from inception to 2021 March, and all studies assessing the safety of LCM were included. A meta-analysis was performed for safety data of LCM. Results: Eighty-three studies involving 12268 populations (11 randomized clinical trials (RCTs), 16 cohort studies, 53 case series, and 3 case reports) were included in our study. Meta-analysis of the total incidence of adverse events (AEs) of LCM was 38.7% [95% CI (35.1%, 45.8%); n=75 studies]. Incidence of withdrawal due to AEs was 10.8% [95% CI (9.1%, 12.6%); n=56 studies], and incidence of serious adverse events (SAEs) was 6.5% [95% CI (4.0%, 8.9%); n=13 studies]. Most AEs were in the nervous system and digestive system. The most common AEs were sedation (15.8%), dizziness (15.7%), fatigue (9.4%), and nausea/vomiting (9.3%). For children, the total incidence of AEs of LCM was 32.8% [95% CI (21.6%, 44.0%); n=16 studies], and the most common AEs were dizziness (8.6%), nausea/vomiting (8.6%), and somnolence (6.8%). Conclusion: Lacosamide is generally safe and well tolerated in patients with epilepsy. Common AEs were sedation, dizziness, and fatigue. It is necessary to pay more attention to the prevention and management of these AEs and conduct more large-scale and high-quality studies to update safety data.

Abstract
Glia, a non-excitable cell type once considered merely as the connective tissue between neurons, is nowadays acknowledged for its essential contribution to multiple physiological processes including learning, memory formation, excitability, synaptic plasticity, ion homeostasis, and energy metabolism. Moreover, as glia are key players in the brain immune system and provide structural and nutritional support for neurons, they are intimately involved in multiple neurological disorders. Recent advances have demonstrated that glial cells, specifically microglia and astroglia, are involved in several neurodegenerative diseases including Amyotrophic lateral sclerosis (ALS), Epilepsy, Parkinson's disease (PD), Alzheimer's disease (AD), and frontotemporal dementia (FTD). While there is compelling evidence for glial modulation of synaptic formation and regulation that affect neuronal signal processing and activity, in this manuscript we will review recent findings on neuronal activity that affect glial function, specifically during neurodegenerative disorders. We will discuss the nature of each glial malfunction, its specificity to each disorder, overall contribution to the disease progression and assess its potential as a future therapeutic target.

Role of observational studies in supporting extrapolation of efficacy data from adults to children with epilepsy - A systematic review of the literature using lacosamide as an example. Eur J Paediatr Neurol 2019; 23:589-603.

Abstract
Extrapolation of efficacy data from adults to children is accepted for focal epilepsy - the antiepileptic drug, lacosamide, has been approved for the treatment of children ≥4 years of age on this basis. Since many small-scale, open-label studies are reported in the literature before approval, a systematic review was conducted to ascertain whether results of these could be used to support extrapolation in epilepsy in the future. In the absence of randomised trials, a second analysis was conducted for reports on lacosamide use in adults with generalized epilepsies. Twenty-seven articles were included in the paediatric qualitative synthesis, and 14 in the adult. Paediatric studies were analysed separately based on seizure type: focal, generalised and mixed. In focal epilepsy, safety and seizure-related findings mirrored those observed in the adult Phase II/III trials, supporting the feasibility of data extrapolation. Few studies reported outcomes in children with epilepsies associated with generalised seizures, and those that included children with different seizure types, mostly did not provide results separately. Lacosamide treatment appeared beneficial for children and adults experiencing tonic-clonic and myoclonic seizures. Reports of seizure aggravation were inconsistent and, in many cases, could not be clearly attributed to lacosamide. Given the absence of sufficient data, evidence for the feasibility of extrapolation was not as clear-cut as it was in focal epilepsy. These results highlight the complexities of conducting trials in the generalised epilepsy setting, and the importance of studies in the real-life setting and of analysing efficacy data per generalized seizure type and syndrome.

Kim DW, Kim HK, Bae EK. Switching from traditional sodium channel blockers to lacosamide in patients with epilepsy. Seizure 2019; 65:172-175. [PMID: 30721874 DOI: 10.1016/j.seizure.2019.01.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2018] [Revised: 01/23/2019] [Accepted: 01/29/2019] [Indexed: 11/17/2022] Open
Abstract
PURPOSE Lacosamide (LCM) is a recently developed sodium channel blocker (SCB), which acts mainly on the slow activation state in sodium channels. Although LCM shares a range of dose-dependent adverse effects with traditional SCBs, it has several advantages in that it does not induce hepatic drug metabolizing enzymes and has less risk of drug interactions and idiosyncratic adverse effects. METHODS We retrospectively analyzed the efficacy and tolerability of switching from traditional SCBs to LCM. The reason for the switch was classified as insufficient efficacy, adverse effects, or concern about metabolic derangement, resulting in conditions such as atherosclerosis and osteoporosis, with long-term use of traditional SCBs. RESULTS Seventy-five patients were switched to LCM from traditional SCBs. The overall rate of successful switching was high (81.3%, 61/75 patients). However, the success rate was strongly dependent on the reason for the switch; patients with insufficient efficacy on SCBs had less chance of a successful switch (71.8%, 28/39 patients) than those with adverse effects (89.5%, 17/19) or concerns about metabolic derangement (94.1%, 16/17, p = 0.038). Patients with insufficient efficacy were significantly younger (p = 0.004) and had a higher chance of drug-resistant epilepsy (p = 0.004) than those in the other two groups. CONCLUSIONS Our study shows that switching from traditional SCBs to LCM is usually successful and the likelihood of a successful switch is higher in patients when the reason for the switch is adverse effects or concerns about metabolic derangement on traditional SCBs.
