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.

Retrospective Multicenter Cohort Study on Safety and Electroencephalographic Response to Lacosamide for Neonatal Seizures. Pediatr Neurol 2024; 155:18-25. [PMID: 38579433 DOI: 10.1016/j.pediatrneurol.2024.03.007] [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: 06/30/2023] [Revised: 02/06/2024] [Accepted: 03/07/2024] [Indexed: 04/07/2024]
Abstract
BACKGROUND There is growing evidence supporting the safety and effectiveness of lacosamide in older children. However, minimal data are available for neonates. We aimed to determine the incidence of adverse events associated with lacosamide use and explore the electroencephalographic seizure response to lacosamide in neonates. METHODS A retrospective cohort study was conducted using data from seven pediatric hospitals from January 2009 to February 2020. For safety outcomes, neonates were followed for ≤30 days from index date. Electroencephalographic response of lacosamide was evaluated based on electroencephalographic reports for ≤3 days. RESULTS Among 47 neonates, 98% received the first lacosamide dose in the intensive care units. During the median follow-up of 12 days, 19% of neonates died, and the crude incidence rate per 1000 patient-days (95% confidence interval) of the adverse events by diagnostic categories ranged from 2.8 (0.3, 10.2) for blood or lymphatic system disorders and nervous system disorders to 10.5 (4.2, 21.6) for cardiac disorders. Electroencephalographic seizures were observed in 31 of 34 patients with available electroencephalographic data on the index date. There was seizure improvement in 29% of neonates on day 1 and also in 29% of neonates on day 2. On day 3, there was no change in 50% of neonates and unknown change in 50% of neonates. CONCLUSIONS The results are reassuring regarding the safety of lacosamide in neonates. Although some neonates had fewer seizures after lacosamide administration, the lack of a comparator arm and reliance on qualitative statements in electroencephalographic reports limit the preliminary efficacy results.

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.

Abstract
AIM To assess the effectiveness and safety of lacosamide (LCM) as the first add-on therapy for children with focal epilepsy at multiple centres in China. METHOD Children aged 4-16 years with focal epilepsy from 13 epilepsy centres were included in this study. All patients were treated with LCM as the first add-on treatment and followed up for 26 weeks. The seizure frequency, seizure-free rate, ≥50% response rate, retention rate, and incidence of adverse drug reactions after the addition of LCM were analysed. RESULTS Ninety-nine children (58 males; aged 4-16 years; mean age 8.51 ± 2.95 years) were enroled. The mean age at first seizure was 5.74 ± 3.12 years. All patients were administered LCM as the first add-on treatment for focal epilepsy. Twenty-eight patients (28/99, 28.28%) did not experience seizures during the follow-up period. The ≥50% response rates were 80.81% (80/99), 93.88% (92/98), 98.98% (97/98), and 100.0% (98/98) at 6 weeks (visit two), 10 weeks (visit three), 18 weeks (visit four), and 26 weeks (visit five), respectively, compared to that at baseline (visit one). The intelligence scores decreased in 12 participants, remained unchanged in 64, and increased in 16. Adverse events occurred in three participants during the trial, all of which were mild. INTERPRETATION LCM was effective as the first add-on therapy in this real-life multi-centre study of a paediatric population with focal epilepsy. Further prospective studies with long-term follow-up periods are needed to confirm the effectiveness and tolerability of LCM.

Abstract
Objectives Levetiracetam (LEV) is a well-established broad spectrum antiseizure medication (ASM) effective in focal, generalized, and myoclonic seizures whereas lacosamide (LCM) is a comparatively newer ASM currently approved only as an add-on agent in focal seizures. The aim of the study was to assess the efficacy and the tolerability of oral LCM as monotherapy in adult people with epilepsy (PWE) with new onset focal onset epilepsy compared with those receiving LEV. Materials and Methods In this open-label single-center non-inferiority trial, PWE aged between 16 and 65 years suffering from new onset focal seizures, with or without secondary generalization were put on LCM monotherapy or LEV monotherapy. Data regarding demographic characteristics, seizure type and etiology, LCM and LEV daily dose, seizure frequency at baseline and at 6 months of follow-up, and seizure freedom rates were recorded. Results Thirty-five PWE on LCM (24 males), their mean age: 38.20 ± 16.62 years and 35 PWE on LEV (25 males, mean age: 38.91 ± 17.13 years) were enrolled. The most common type of seizure observed was focal to bilateral tonic-clonic seizure >70% followed by focal impaired awareness seizure and focal awareness seizure. Structural epilepsy was found in 21 among LCM group and 22 of LEV group. In the LCM group, the seizure frequency decreased from 3.33 ± 1.88 to 0.85 ± 1.09 (P = 0.001) at 6 months and from 3.61 ± 3.12 to 0.94 ± 1.24 (P = 0.001) in LEV group, intergroup difference (P = 0.74). At 6-month follow-up period, 78.9% in LCM arm and 87.9% in the LEV arm had experienced a 50% of reduction in seizure frequency while seizure freedom was attained in 43.3% of PWE in both the arms (P = 1). The most common treatment emergent adverse effects in the LCM group were fatiguability, dyspepsia, headache, and dizziness, while in the LEV group; somnolence and behavioral abnormality. Conclusion Treatment with LCM met the non-inferiority criteria when compared with LEV. Therefore, it might be useful as first-line monotherapy for adults with newly diagnosed focal epilepsy.

Abstract
Objective: This study aimed to investigate the efficacy and tolerability of Lacosamide (LCM) in a pediatric population with epilepsy using LCM serum concentration and its correlation to the age of the participants and the dosage of the drug. Methods: Demographic and clinical data were collected from the medical records of children with epilepsy treated with LCM at Shamir Medical Center between February 2019 to September 2021, in whom medication blood levels were measured. Trough serum LCM concentration was measured in the biochemical laboratory using High-Performance Liquid Chromatography (HPLC) and correlated with the administered weight-based medication dosing and clinical report. Results: Forty-two children aged 10.43 ± 5.13 years (range: 1-18) were included in the study. The average daily dose of LCM was 306.62 ± 133.20 mg (range: 100-600). The average number of seizures per day was 3.53 ± 7.25 compared to 0.87 ± 1.40 before and after LCM treatment, respectively. The mean LCM serum concentration was 6.74 ± 3.27 mg/L. No statistically significant association was found between LCM serum levels and the clinical response (p = 0.58), as well as the correlation between LCM dosage and the change in seizure rate (p = 0.30). Our study did not find a correlation between LCM serum concentration and LCM dosage and the gender of the participants: males (n = 17) females (n = 23) (p = 0.31 and p = 0.94, respectively). A positive trend was found between age and LCM serum concentrations (r = 0.26, p = 0.09). Conclusion: Based on the data that has been obtained from our study, it appears that therapeutic drug monitoring for LCM may not be necessary. Nonetheless, further research in this area is needed in the light of the relatively small sample size of the study.

Abstract
Epilepsy is a chronic neurological disorder associated with severe social and psychological effects, and most epilepsy patients often report at least one comorbidity. Accumulating evidence have suggested that lacosamide, a new generation of anti-seizure medications, may exhibit efficacy in the management of both epilepsy and its related comorbidities. Therefore, this narrative review aimed to elucidate the recent advancements regarding the therapeutic role of lacosamide in epilepsy-associated comorbidities. The possible pathophysiological mechanisms between epilepsy and epilepsy-associated comorbidities have been also partially described. Whether lacosamide improves cognitive and behavioral functions in patients with epilepsy has not been conclusively established. Some studies support that lacosamide may alleviate anxiety and depression in epilepsy patients. In addition, lacosamide has been found to be safe and effective in the treatment of epilepsy in people with intellectual disabilities, epilepsy of cerebrovascular etiology, and epilepsy associated with brain tumors. Moreover, lacosamide treatment has demonstrated fewer side effects on other systems. Hence, future larger and higher quality clinical studies are needed to further explore both the safety and efficacy of lacosamide in the treatment of epilepsy-associated comorbidities.

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.

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.

Abstract
Purpose
Lennox–Gastaut syndrome (LGS) is one of the most difficult to treat childhood-onset epileptic encephalopathies. There is growing evidence that lacosamide is safe and efficacious in patients and adults with refractory epilepsy. However, the evidence regarding the efficacy of lacosamide in LGS is controversial so far. We aimed to evaluate the efficacy and tolerability of lacosamide in patients with LGS.
Methods
We conducted a systematic review on MEDLINE, EMBASE, COCHRANE CENTRAL, Google Scholar, and Web of Science, collating all available literature till July 31, 2020. The qualitative review included case reports, case series, and both controlled/uncontrolled trials as well as retrospective studies, but for determining pooled estimates, we only included studies with a sample size of 5 or more. The primary outcome was the efficacy of lacosamide in patients with LGS. Clinical variables related to efficacy and adverse events attributed to lacosamide were extracted from each publication. The pooled estimate of variables related to these parameters was performed using a random-effect model.
Results
Of the 68 items identified by the search, 14 were reviewed as full-text. Eleven articles including two prospective and six retrospective studies fulfilled eligibility criteria and described outcomes in 81 patients (42 adults, 39 children, 60% male, range—1.4–61 years). On average, 35.2%, 27.9%, 7.3%, and 29.4% patients had > 50% reduction, < 50% reduction, no change, and worsening of seizure frequency, respectively. Although 36% of patients had adverse events like somnolence, behavioral abnormalities including irritability, aggressiveness, nausea, tremor, memory problems, dizziness, gastrointestinal discomfort, vomiting, and weight loss, no serious adverse events were noted.
Conclusion
The evidence available in the current literature is not sufficient to support or refute the use of lacosamide in patients with LGS. Although it is one of the possible therapeutic options worth exploring in patients with LGS, caution is still necessary, as there are reports of worsening of seizure frequency in some patients.

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
PURPOSE Lacosamide (LCM) was approved in China in 2018. However, the safety of LCM has not been established in pediatric patients. Therefore, the objective of this study was to investigate its safety, efficacy, and tolerability in pediatric patients living in Uygur, Northwest China. METHODS This is a retrospective analysis of pediatric patients diagnosed with epilepsy and on LCM therapy at a medical center. The seizure frequencies at 3, 6, and 12 months after starting LCM therapy were recorded and compared with the baseline monthly frequency. The primary outcome variables were the 50% responder and seizure-free rates. The secondary outcome variables included the terminal 6-month seizure remission and percentages of discontinuation due to a lack of efficacy and tolerability. Safety variables included the incidence and type of adverse reactions. RESULTS Seventy-two pediatric patients with epilepsy living in Uygur, China and receiving LCM treatment were included in the present study. Fifty (69%) children responded to LCM therapy with a more than 50% reduction in the frequency of seizures. Seizure-free rates increased over time, at 14%, 19%, and 20% at 3, 6, and 12 months, respectively. The number of baseline anti-seizure medications (ASMs) and order of LCM introduction significantly impacted the likelihood of seizure remission during the 12-month follow-up period (p < 0.05). During the entire period of LCM treatment, twenty-two children (30.5%) experienced at least one adverse reaction. CONCLUSION This retrospective study of 72 pediatric patients with epilepsy in Uygur, China, showed that LCM therapy is safe and effective for epilepsy in children, resulting in a reduction in the seizure rate.

Abstract
PURPOSE The aim of this study was to evaluate the tolerability and efficacy of lacosamide (LCM) in Lebanese children with focal-onset seizures and to determine if specific variables are predictive of better effectiveness. METHODS This is a retrospective analysis from three medical centers on consecutive children diagnosed with focal onset seizures and initiated on LCM. The seizure frequencies following the introduction of LCM were recorded and compared to the baseline monthly frequency at 3, 6, 12, 18, and 24 months. The primary efficacy variables were the 50% responder and seizure-free rates. The secondary outcome variables included the terminal 6-month seizure remission and percentages of discontinuation due to lack of efficacy or tolerability. RESULTS 58 patients with a mean age of 10 years experiencing a mean of 36.2 seizures per month during baseline were included. The seizure-free rates were 32.8%, 29.7%, and 12.5% at 6, 12 and 24 months follow up, respectively. Patients concomitantly treated with a sodium channel blocker were less likely to achieve a terminal 6-month seizure remission while the early introduction of LCM resulted in a significantly higher likelihood of attaining such a remission. 74.1% of patients were still maintained on LCM at the last follow-up. The most common adverse events consisted of dizziness, somnolence, nausea, vomiting, and rarely double vision. CONCLUSIONS LCM is efficacious and overall well tolerated in children with focal-onset seizures and exhibits higher efficacy with early introduction and when added to a non-sodium channel blocker.

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.

Abstract
PURPOSE To evaluate safety and tolerability of adjunctive lacosamide in children with focal seizures. METHODS Patients were eligible for this open-label, fixed-titration trial (SP0847; NCT00938431) if aged 1 month-17 years with focal seizures taking 1-3 antiepileptic drugs. Findings from Cohort 1, aged 5-11 years, who received lacosamide ≤8 mg/kg/day, informed dosing for age-based cohorts 2-5, who then received ≤12 mg/kg/day (≤600 mg/day). Oral lacosamide was initiated at 2 mg/kg/day (1 mg/kg bid) and uptitrated by 2 mg/kg/day/week to the maximum cohort-defined dose (maximum trial duration: 13 weeks). Patients who did not achieve the maximum cohort-defined dose were discontinued. RESULTS Forty-seven patients (aged 6 months-≤17 years) enrolled (≥1 month-<4 years: n = 15; ≥4-<12 years: n = 23; ≥12-≤17 years: n = 9). 24/47 (51.1%) patients completed the trial at the maximum cohort-defined dose and 40/47 (85.1%) continued lacosamide in the extension trial. Treatment-emergent adverse events (TEAEs) were reported by 42/47 (89.4%) patients. The most common TEAEs (≥10% of patients) were vomiting (21.3%), diarrhea (14.9%), somnolence (12.8%), irritability, dizziness, and pyrexia (10.6% each). Twenty (42.6%) patients discontinued due to TEAEs, most commonly vomiting (8.5%), gait disturbance, dizziness, and somnolence (6.4% each). Six (12.8%) patients reported serious TEAEs, most commonly status epilepticus (3/47; 6.4%). CONCLUSION This fixed-titration trial supports the safety of adjunctive lacosamide in children (aged 6 months-≤17 years) with focal seizures. The TEAE profile was generally consistent with that observed in trials in adults, and no new safety concerns were identified.

Abstract
AIM To assess the effectiveness and tolerability of lacosamide in paediatric clinical practice. METHODS A search of our hospital's pharmacy database yielded all children <16 years old dispensed lacosamide for drug-resistant epilepsy between January 2011 and June 2016. Medical records were reviewed for clinical and drug details. Continued treatment for ≥12 months was considered an indicator of effectiveness and tolerability. RESULTS A total of 107 children (61 boys) satisfied inclusion criteria. Median age at lacosamide commencement was 9.9 years (interquartile range 6.7-13.7). Of those children, 57 (53%) children had focal epilepsy, with focal motor or impaired awareness seizures most commonly reported; 50 (47%) children had generalised epilepsy, most with tonic-clonic seizures, tonic seizures or epileptic spasms; 83 (78%) children had an intellectual disability, 24 (22%) had a physical disability and 22 (21%) had an autism spectrum disorder; 69 (65%) children continued lacosamide for ≥12 months. Reasons for discontinuation before 12 months in 38 (35%) children included ineffectiveness in 25 (66%), adverse events in 7 (18%) and worsening of seizures in 2 (5%). The most common adverse events were drowsiness, behavioural changes, unsteadiness, nausea and vomiting. Epilepsy type and comorbidities were not associated with continuation or reasons for discontinuation. CONCLUSIONS Most children continued treatment with lacosamide, suggesting effectiveness and tolerability. Lacosamide may prove to be a useful, 'broad-spectrum' antiepileptic medication in children for focal and generalised epilepsies and in association with comorbidities.

Abstract
Among individuals diagnosed with epilepsy, as many as one in three develop resistance to antiepileptic drugs (AEDs) thus rendering their seizures refractory to treatment. Despite current antiepileptic drugs (AEDs) having a variety of modes of action, seizures in drug-resistant individuals often persist even after treatment with two or more drugs. The underlying cause of this broad resistance is currently under debate, but two dominant theories have emerged and have been widely studied. Here we discuss current literature investigating the "transporter theory", the idea that individuals present with drug resistance due to genetic variability in the ABCB1 gene encoding the efflux transporter multidrug resistance protein 1 (MDR1). Results of in vitro and in vivo studies suggest that variability in the expression of the MDR1 transporter may be closely tied to drug resistance. While there is much support for this hypothesis from molecular and mechanistic studies, population-based studies of ABCB1 polymorphisms are divergent in their conclusions, and there is need for additional investigations.

Abstract
INTRODUCTION Treatment of pediatric epilepsy requires a careful evaluation of the safety and tolerability profile of antiepileptic drugs (AEDs) to avoid or minimize as much as possible adverse events (AEs) on various organs, hematological parameters, and growth, pubertal, motor, cognitive and behavioral development. AREAS COVERED Treatment-emergent AEs (TEAEs) reported in the literature 2000-2018 regarding second- and third-generation AEDs used in the pediatric age, with exclusion of the neonatal period that exhibits specific peculiarities, have been described on the basis of their frequency, severity/tolerability, and particular association with a given AED. EXPERT OPINION Somnolence/sedation and behavioral changes, like irritability and nervousness, are among the most commonly observed TEAEs associated with almost all AEDs. Lamotrigine, Gabapentin, Oxcarbazepine, and Levetiracetam appear to be the best-tolerated AEDs with a ≤2% withdrawal rate, while Tiagabine and Everolimus are discontinued in up to >20% of the patients because of intolerable TEAEs. For some AEDs, literature data are scanty to draw a high-level evidence on their safety and tolerability profile. The reasons are: insufficient population size, short duration of treatments, or lack of controlled trials. A future goal is that of identifying clearer, easier, and more homogeneous methodological strategies to facilitate AED testing in pediatric populations.

Effectiveness and Adverse Effect of Intravenous Lacosamide in Nonconvulsive Status Epilepticus and Acute Repetitive Seizures in Children. Neurol Res Int 2018; 2018:8432859. [PMID: 29984000 PMCID: PMC6015664 DOI: 10.1155/2018/8432859] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Revised: 04/04/2018] [Accepted: 05/06/2018] [Indexed: 11/18/2022] Open
Abstract
Nonconvulsive status epilepticus (NCSE) and acute repetitive seizures (ARS) are associated with significant morbidity and mortality. Due to the lack of randomized-controlled trials of intravenous antiepileptic drugs (AEDs) in these conditions, trials of a new generation of AEDs in this aspect are needed. A prospective interventional study was conducted in children under 18 years of age with NCSE or ARS who either had contraindication to or were refractory to first-line AEDs and received intravenous lacosamide. Demographic data, the efficacy of treatment, and adverse effects were recorded. Eleven patients with a median age of 11 years, predominantly female (72.7%), were enrolled. Average loading dose was 227 mg (8.3 mg/kg/dose) and average daily maintenance dose was 249 mg (4.6 mg/kg/dose). All patients (100%) experienced a reduction in seizure frequency within 24 hours. Eight of eleven patients (72.7%) experienced a reduction in seizure frequency of more than 50% by the end of the study, and one patient became seizure-free. In terms of adverse events, one patient had a bradycardia without prolongation of the PR interval. Interestingly, there was a case of neuronal ceroid lipofuscinosis in which a significant improvement in seizure control was achieved. The results indicate that intravenous lacosamide may be an alternative treatment for NCSE or ARS in children. To our knowledge, this is the first study on the use of intravenous lacosamide in Asian children. This study is registered to Thai Clinical Trials Registry (TCTR) and the trial registration number is TCTR20180508004.

Abstract
Lacosamide (Vimpat®) is a functionalized amino acid (available orally and intravenously) approved in the EU and the USA for use as monotherapy and adjunctive therapy for the treatment of focal-onset seizures in adults, adolescents and children aged ≥ 4 years with epilepsy. In adults and adolescents (aged ≥ 16 years), oral lacosamide as adjunctive therapy to other antiepileptic drugs was generally effective in reducing seizure frequency during short-term (up to 18 weeks) treatment, with efficacy sustained over the longer-term (up to 8 years). Moreover, patients were effectively switched from adjunctive oral lacosamide to the same dosage of intravenous lacosamide. Oral lacosamide was an effective conversion to monotherapy agent in this patient population and as monotherapy demonstrated noninferiority to carbamazepine controlled release in terms of seizure freedom. Antiepileptic benefits were maintained during longer-term (≤ 2 years) monotherapy. The antiepileptic efficacy of lacosamide in children aged ≥ 4 years has been extrapolated from data from adults and adolescents, with a similar response expected provided paediatric dosage adaptations are used and safety is demonstrated. Indeed, preliminary data demonstrated the efficacy of short-term (16 weeks) adjunctive lacosamide in patients aged ≥ 4 to < 17 years. Oral lacosamide was generally well tolerated over the short- and longer-term when administered as adjunctive therapy, a conversion to monotherapy agent and monotherapy in adults and adolescents and when administered as adjunctive therapy in children aged ≥ 4 years. Thus, lacosamide is a useful option for the management of focal-onset seizures across a broad age range, starting as early as 4 years of age.

Abstract
BACKGROUND Seizures in up to 30% of children with epilepsy become refractory to treatment, decreasing their quality of life. Studies suggest that lacosamide may be effective in pediatric patients with refractory epilepsy. AIMS To assess the effectiveness and safety of lacosamide in a population of children with mostly focal refractory epilepsy. METHODS Retrospective analysis of children aged <18years presenting to a single hospital in Spain. Data from baseline, and 3, 6, and 12months after lacosamide initiation were collected and analyzed. Response to lacosamide was categorized by seizure frequency (seizure freedom or ≥75%, ≥50%, and <50% reduction in seizures). RESULTS One hundred ninety-one pediatric patients (~55% male) with focal epilepsy treated with lacosamide were included. The mean age at lacosamide initiation was 9.4years, and the mean duration of epilepsy was 5.4years. Seizure-free rates at 3, 6, and 12months were 9.7%, 11.8%, and 16.0%. At 12months, 44.4% of the population had a ≥50% reduction in seizure frequency. When analyzing response according to the number of previous/concomitant AEDs, those patients who received ≤2 previous AEDs/fewer concomitant AEDs had significantly greater response rates than those who received greater numbers of previous/concomitant AEDs; however, no predictive factors for response were identified. The most common adverse events were seizure number increased (14.7%), diplopia (5.2%), dizziness (3.7%), ataxia (2.1%), and drowsiness (2.1%). CONCLUSIONS Lacosamide use in children with refractory focal epilepsy can result in a reduction in seizure rate that improves progressively over time with few adverse effects, making lacosamide a promising option in these patients.

Abstract
PURPOSE Lacosamide (LCM) is an effective antiepileptic drug (AED) approved for the treatment of focal epilepsy in both children and adults. The aim of this observational study was to review our centre's experience with LCM and to characterise its efficacy and tolerability as an adjunct therapy in children with refractory focal epilepsy. METHODS We retrospectively reviewed the medical records of 12 paediatric patients who underwent treatment with LCM from January 2014 to December 2015. We recorded the treatment response at three time points: at 3 and 6 months after LCM therapy and at the final follow-up visit. Children showing seizure reduction ≥ 50% were considered responders. RESULTS We included 12 patients (five boys), and their mean age was 13.8 years (range: 6.2-17.6 years) at the end of LCM treatment. The average length of follow-up after starting LCM was 23 months (11-37 months). Eight patients (66%) had > 50% reduction in seizures at the 3-month follow-up visit, and seven (58%) had > 50% reduction at the 6-month follow-up visit. Six patients (50%) maintained ≥ 50% reduction in seizures at the final follow-up visit. Two patients (16.6%) were seizure free at the 6-month and final follow-up visits. Common adverse side effects included dizziness, ataxia, nausea, and vomiting. Two patients developed status epilepticus (SE), one each at 3 and 11 days after the first LCM dose; they both discontinued treatment. CONCLUSIONS Our study points to the efficacy of LCM in a small paediatric group. Furthermore, it was important to report status epilepticus after LCM administration in the paediatric population for the first time.

Abstract
Lacosamide is FDA-approved in patients 17 years or older with partial-onset epilepsy. We evaluated the efficacy and tolerability of lacosamide in children with refractory generalized epilepsy. We retrospectively reviewed records of 21 children with refractory generalized epilepsy treated with lacosamide in our institution from 2009-2013 divided into 2 subgroups- I, Lennox-Gastaut Syndrome, and II, other generalized epilepsies. Efficacy was defined as seizure freedom or ≥50% seizure reduction. Descriptive data analysis including seizure freedom was compared using c(2) analysis. There were eleven females and ten males with a mean age, of 11.9 years. Five patients became seizure free, nine had ≥50% seizure reduction, and seven had no response. Group I: seven had ≥50% improvement, one did not respond. Group II: five became seizure free, two had ≥50% improvement, five had no response. Lacosamide is effective and well tolerated in children with refractory generalized epilepsy particularly patients with Lennox-Gastaut Syndrome.

Abstract
OBJECTIVE To review our clinical experience with intravenous (iv) lacosamide (LCM) in children less than 12 years old. BACKGROUND Use of LCM to treat children with epilepsy has been supported by multiple studies with limited information on iv use in children. DESIGNS/METHODS All children given iv LCM were identified from 2009 to 2015. Records were audited for demographics, seizure classification, etiology, EEG, imaging, indication. Baseline seizure frequency was based on parental reporting, continuous video EEG and direct observation. RESULTS 47 patients were identified with median age 6.5 years, 18 less than 3 years old, including 8 younger than 12 months. LCM was an adjunctive therapy of ≥2 antiepileptic drugs (AEDs). LCM was administered intravenously to treat epilepsia partialis continua (n = 3, dose range 5-10 mg/kg), status epilepticus (n = 11, median dose 7.2 mg/kg, range 4-11 mg/kg), and acute exacerbation of seizure frequency (n = 18, median dose 4.5 mg/kg, range 1-11 mg/kg). Parenteral form was substituted for oral form for 10 children treated with maintenance LCM unable to ingest/tolerate enteral medication and 5 who were given iv LCM to initiate maintenance treatment (median dose 4 mg/kg, range: 2-10 mg/kg). The infusion was effective for 24 out of 37 children (65%) naive to LCM. Sedation (one with ataxia) was noted in 5/36 children (14%), without any other identified adverse events. CONCLUSION This is the first published retrospective study of very young critically ill children receiving iv LCM. The acute tolerability at this dosing range represents a positive trend and need confirmation from larger studies.

Abstract
PURPOSE To evaluate the efficacy, safety, and tolerability of lacosamide in adults with LGS in the clinical setting. METHOD The present report is a retrospective, open-label treatment study carried out from June 2013 to December 2014 at the National Institute of Colombia. Lacosamide was introduced as add-on therapy. All caregivers were instructed to initiate lacosamide at low doses (25-50 mg) and gradually increasing it every 2 weeks. The efficacy was evaluated based on the reduction in the rate of each countable type of seizure. We also evaluated the retention rate for lacosamide as the number of days with lacosamide during follow-up. The tolerability was evaluated base on account the adverse events. RESULTS We found that lacosamide only improves the seizure rate in three out of 19 patients with LGS, in two of them by more than 50%. The highest seizure reduction rate was observed in the focal and tonic-clonic seizures. The most commonly reported adverse events were worsening of seizures, aggressiveness and irritability. Nine patients (47.4%) showed worsening of their behavior during the treatment with lacosamide. CONCLUSION Lacosamide can exacerbate both, the tonic and astatic seizures, and the encephalopathy associated with this epileptic syndrome. However, it is interesting to consider the likelihood of suppression of generalized tonic-clonic and focal seizures. That is why; lacosamide could be an option after carefully balancing risks and benefits in each individual case.

Abstract
AIMS Lacosamide (LCM) is a novel anti-epileptic drug (AED) that enhances the slow inactivation of voltage-gated sodium channels. Its efficacy as adjunctive therapy for focal seizures is confirmed in adult placebo controlled trials with >50% reduction in seizure frequency in up to 50% patients. There is paucity of data on its efficacy and tolerance in treatment-resistant epilepsy in childhood (TREC). This study aims to assess efficacy and tolerance of LCM as adjunct therapy in TREC. METHODS Audit of medical records and seizure diaries in children with TREC on LCM. A response (RR) was defined as ≥50% reduction in seizure frequency. RESULTS Forty children (age range: 2-19 years) with TREC received LCM as add-on therapy. All had abnormal electroencephalograms, and 36 had abnormal neuroimaging. All children failed >2 AED trials, nine had trialled the ketogenic diet, five had failed the vagal nerve stimulator and 11 had failed resective epilepsy surgery. Median dose and duration of LCM therapy were 5.7 mg/kg/day and 10.5 months, respectively. RR was seen in 20% with persistence of RR in 8/36, 8/30 and 8/26 children on LCM at 3-, 6- and 9-month follow-up. Two children became seizure free. Retention on LCM was 65% at 9 months. LCM was well tolerated with minor side effects in seven children; no child discontinued LCM because of side effects. CONCLUSION LCM is a well-tolerated AED with RR in 20%: in 5%, it resulted in seizure freedom. LCM may be useful even in TREC when seizures have not responded to intervention with multiple modalities.

Abstract
OBJECTIVES The study was carried out to investigate the safety of lacosamide on children with refractory partial epilepsy. MATERIALS & METHODS The study was carried out at a tertiary care hospital after obtaining approval from the institutional ethics committee. Patients aged between 5 and 15 years taking oral lacosamide (LCM) tablets that were given orally as an adjunctive anti-epileptic drug were enrolled for assessing safety, tolerability and its effect on the behavioural life at every visit of titration, during the treatment period (3 months) and at 2 follow up visits that were done at monthly intervals. Adverse events reported by caregiver or by investigator were recorded. Patients/caregivers also completed a 25 items on Connor's behavioural rating clinical scale at every visit. RESULTS Out of 531 screened patients, 79 patients with refractory partial epilepsy were enrolled after they fulfilled the inclusion and exclusion criteria. Mean age of the children was 8.84 ± 3.09 years (5-15 years), of which 53 were males and 26 females. The mean age at onset of seizures in males was 6.46 ± 3.57 and in females, 6.38 ± 3.39 years. Seventy-six children of 79, completed 3 months of treatment period showed significant (p < 0.001) decrease in the frequency of seizures, significant improvement in behaviour and showed good tolerability. Three (3.79%) patients dropped out of the study due to hyperactive behaviour, vomiting and lack of seizure control respectively. CONCLUSIONS Lacosamide is a well-tolerated newer antiepileptic drug that is effective in refractory partial epilepsy paediatric patients and concurrently improved patient's behaviour.

Abstract
BACKGROUND A unicentre, prospective study was performed to investigate the efficacy of lacosamide as adjunctive therapy in children with refractory partial epilepsy. METHODS The study was performed at a tertiary care hospital over a period of 30 months between November 2011 and May 2014. Seventy-nine children with refractory partial epilepsy (age 5-15 years) who had failed two or more antiepileptic drugs and in whom lacosamide was used as an add-on drug were enrolled. Lacosamide tablets were administered orally, at a dose of 25 mg for 1 week followed by 50 mg twice daily for the remaining period. Efficacy and tolerability evaluation was performed at every visit of titration, maintenance period (3 months), and two follow-up visits at monthly interval. Electrocardiogram and liver function tests were performed before enrollment and at the end of 3 months of lacosamide therapy. Patient's caregiver or investigator observed adverse events were recorded in a predesigned pro forma. RESULTS A total of 79 patients with uncontrolled partial epilepsy screened from 531 epileptic children were enrolled, after they satisfied the inclusion and exclusion criteria. The mean age of children enrolled was 8.8 ± 3.1 years (range 5-15 years); 53 children (67.0%) were boys. Mean weight of the patients was 24.2 ± 9.8 kg. The mean age at the onset of seizures was 6.4 ± 3.5 years. The mean dose of lacosamide administered was 4.1 mg/kg. Three patients (3.8%) dropped out of the study, because of vomiting, aggressive behavior, and poor response, respectively. Of 76 patients (96.2%) entering the maintenance period, 35 patients (44.3%) were seizure free, 32 patients (40.6%) indicated ≥50% reduction in seizure frequency, 3 patients (3.8%) indicated 25-49% seizure reduction, and 9 patients (11.4%) either had no change in seizure frequency or experience increase in seizure frequency. CONCLUSION Lacosamide is an effective add-on antiepileptic drug for children with refractory partial epilepsy and is well tolerated.

Abstract
OBJECTIVE Available data on the efficacy of lacosamide in children with Lennox-Gastaut syndrome (LGS) are scarce and controversial. We present our experience with lacosamide therapy in children affected by LGS. MATERIAL AND METHODS Medical charts of all children affected by LGS receiving oral lacosamide adjunctive therapy in six paediatric neurology centres were retrospectively evaluated. Efficacy was determined according to the frequency of countable seizures during the 4 weeks prior to treatment and the frequency in the last 4 weeks of observation. Patients whose seizure frequency was reduced by at least 50% were defined as responders. RESULTS Eighteen children (mean age 12.3 years) were identified. After a mean follow-up period of 9 months, 33% of patients were responders. None of them was seizure-free during the study period. The overall seizure reduction rate was 29%. The percentage reductions from baseline in tonic seizures and drop-attacks rates were 31% and 20%, respectively. Adverse reactions occurred in 44% of patients. The drug was discontinued in four (22%) patients because of increased seizure frequency (three cases) and walking instability (another patient). CONCLUSIONS A third of children with LGS were responders after lacosamide adjunctive therapy. Although caution is still necessary when the drug is used in children with LGS, our preliminary observations suggest that lacosamide might be effective and represent a possible therapeutic option in children affected by LGS.

Abstract
BACKGROUND Lacosamide is effective and well-tolerated antiepileptic drug (AED) in both children and adults. AIM This multicentric, prospective study investigates the efficacy and safety of lacosamide adjunctive therapy in children aged less than four years presenting with refractory focal seizures. METHODS Lacosamide was added to the baseline therapy at a starting dose of 1-2 mg/kg/day and titrated to the final dose, ranging from 7 to 15.5 mg/kg/day. Efficacy was evaluated after a three-month period of therapy. When possible, we compared the initial efficacy and the retention after a minimum of 12 months of lacosamide, with regard to loss of efficacy (defined as the return to the baseline seizure frequency). RESULTS Twenty-four children were enrolled in the study. Mean age was 2.7 years. After a minimum three-month period of lacosamide add-on therapy, ten (42%) patients were responders (more than a 50% decrease in seizure frequency), of whom 4 (17%) became seizure free. Retention rate, after a minimum of 12 months of lacosamide, was evaluated in a group of 18 patients. In the latter group, eight patients (44%) were initial responders (three of whom seizure free). After 12 months of follow-up, four of them (22%) maintained the improvement, 2 (11%) of whom remained seizure free. A loss of efficacy was observed in 4 of the initial responders (50%). Adverse events were seen in 8 (33%) patients. CONCLUSION We conclude that lacosamide is an effective and a well-tolerated antiepileptic drug in an etiologically wide range of focal seizures. Therefore, lacosamide might represent a possible therapeutic option in infants and young children affected by uncontrolled focal epilepsy.

Control of seizures in different stages of partial epilepsy: LACO-EXP, a Spanish retrospective study of lacosamide. Epilepsy Behav 2013; 29:349-56. [PMID: 23999191 DOI: 10.1016/j.yebeh.2013.07.024] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2013] [Revised: 07/25/2013] [Accepted: 07/29/2013] [Indexed: 02/08/2023]
Abstract
Lacosamide is approved as adjunctive therapy for focal epilepsies. The number of antiepileptic drugs (AEDs) tried is associated with prognosis. This multicenter, retrospective, observational study (LACO-EXP) in Spain in 500 adult patients with focal epilepsies examined the efficacy and tolerability of add-on lacosamide. Factors associated with better efficacy/tolerability were analyzed. After 12months, the responder rate (≥50% reduction in seizure frequency) was 57.1%, and the seizure-free rate was 14.9%. Efficacy was better when lacosamide was the first or second add-on AED, although there was a small chance to be seizure-free even for patients who had received ≤10 prior AEDs. The mechanism of action of concomitant AEDs is important in all the stages, but differences are smaller in the early stages. Lacosamide was generally well tolerated. A slower dosage-titration schedule was associated with a lower adverse event rate. Further investigation of the timing of initiation of lacosamide add-on therapy and ideal combinations of AEDs is required.
