Neurological adverse events of new generation sodium blocker antiepileptic drugs. Meta-analysis of randomized, double-blinded studies with eslicarbazepine acetate, lacosamide and oxcarbazepine.
Analysis of overall tolerability and neurological adverse effects (AEs) of eslicarbazepine acetate (ESL), lacosamide (LCM) and oxcarbazepine (OXC) from double-blind, placebo-controlled trials. Indirect comparisons of patients withdrawing because of AEs, and the incidence of some vestibulocerebellar AEs between these three antiepileptic dugs (AEDs).. We searched MEDLINE for all randomized, double-blind, placebo-controlled trials investigating therapeutic effects of fixed oral doses of ESL, LCM and OXC in patients with drug resistant epilepsy. Withdrawal rate due to AEs, percentages of patients with serious AEs, and the proportion of patients experiencing any neurological AE, nausea and vomiting were assessed for their association with the experimental drug. Analyses were performed between recommended daily doses of each AED according to the approved summary of product characteristics (SPC). Risk differences were used to evaluate the association of any AE [99% confidence intervals (CIs)] or study withdrawals because of AEs (95% CIs) with the experimental drug. Indirect comparisons between withdrawal rate and AEs dizziness, coordination abnormal/ataxia and diplopia were estimated according to network meta-analysis (Net-MA).. Eight randomized, placebo-controlled, double-blind trials (4 with ESL, 3 with LCM, and 1 with OXC) were included in our analysis. At high doses (OXC 1200mg, ESL 1200mg and LCM 400mg) there was an increased risk of AE-related study withdrawals compared to placebo for all drugs. Several AEs were associated with the experimental drug. Both number and frequency of AEs were dose-related. At high recommended doses, patients treated with OXC withdrew from the experimental treatment significantly more frequently than patients treated with ESL and LCM. Furthermore, the AEs coordination abnormal/ataxia and diplopia were significantly more frequently observed in patients treated with OXC compared to patients treated with LCM and ESL.. The overall tolerability of AEDs and the incidence of several neurological AEs were clearly dose-dependent. Indirect comparisons between these AEDs, taking into account dose-effect, showed that OXC may be associated with more frequent neurological AEs than LCM and ESL.

Efficacy and safety of adjunctive lacosamide in the treatment of primary generalised tonic-clonic seizures: a double-blind, randomised, placebo-controlled trial.
To evaluate efficacy and safety of lacosamide (up to 12 mg/kg/day or 400 mg/day) as adjunctive treatment for uncontrolled primary generalised tonic-clonic seizures (PGTCS) in patients (≥4 years) with idiopathic generalised epilepsy (IGE).. Phase 3, double-blind, randomised, placebo-controlled trial (SP0982; NCT02408523) in patients with IGE and PGTCS taking 1-3 concomitant antiepileptic drugs. Primary outcome was time to second PGTCS during 24-week treatment.. 242 patients were randomised and received ≥1 dose of trial medication (lacosamide/placebo: n=121/n=121). Patients (mean age: 27.7 years; 58.7% female) had a history of generalised-onset seizures (tonic-clonic 99.6%; myoclonic 38.8%; absence 37.2%). Median treatment duration with lacosamide/placebo was 143/65 days. Risk of developing a second PGTCS during 24-week treatment was significantly lower with lacosamide than placebo (Kaplan-Meier survival estimates 55.27%/33.37%; HR 0.540, 95% CI 0.377 to 0.774; p<0.001; n=118/n=121). Median time to second PGTCS could not be estimated for lacosamide (>50% of patients did not experience a second PGTCS) and was 77.0 days for placebo. Kaplan-Meier estimated freedom from PGTCS at end of the 24-week treatment period (day 166) for lacosamide/placebo was 31.3%/17.2% (difference 14.1%; p=0.011). More patients on lacosamide than placebo had ≥50% (68.1%/46.3%) or ≥75% (57.1%/36.4%) reduction from baseline in PGTCS frequency/28 days, or observed freedom from PGTCS during treatment (27.5%/13.2%) (n=119/n=121). 96/121 (79.3%) patients on lacosamide had treatment-emergent adverse events (placebo 79/121 (65.3%)), most commonly dizziness (23.1%), somnolence (16.5%), headache (14.0%). No patients died during the trial.. Lacosamide was efficacious and generally safe as adjunctive treatment for uncontrolled PGTCS in patients with IGE.

Long-term safety and efficacy of lacosamide and controlled-release carbamazepine monotherapy in patients with newly diagnosed epilepsy.
A large-scale, double-blind trial (SP0993; NCT01243177) demonstrated that lacosamide was noninferior to controlled-release carbamazepine (carbamazepine-CR) in terms of efficacy, and well tolerated as first-line monotherapy in patients (≥16 years of age) with newly diagnosed epilepsy. We report primary safety outcomes from the double-blind extension of the noninferiority trial (SP0994; NCT01465997) and post hoc analyses of pooled long-term safety and efficacy data from both trials.. Patients were randomized 1:1 to lacosamide or carbamazepine-CR. Doses were escalated (lacosamide: 200/400/600 mg/d; carbamazepine-CR: 400/800/1200 mg/d) based on seizure control. Eligible patients continued randomized treatment in the extension. Primary outcomes of the extension were treatment-emergent adverse events (TEAEs), serious TEAEs, and discontinuations due to TEAEs. Post hoc analyses of data from combined trials included 12- and 24-month seizure freedom and TEAEs by number of comorbid conditions.. A total of 886 patients were treated in the initial trial and 548 in the extension; 211 of 279 patients (75.6%) on lacosamide and 180/269 (66.9%) on carbamazepine-CR completed the extension. In the extension, 181 patients (64.9%) on lacosamide and 182 (67.7%) on carbamazepine-CR reported TEAEs; in both groups, nasopharyngitis, headache, and dizziness were most common. Serious TEAEs were reported by 32 patients (11.5%) on lacosamide and 22 (8.2%) on carbamazepine-CR; 12 (4.3%) and 21 (7.8%) discontinued due to TEAEs. In the combined trials (median exposure: lacosamide 630 days; carbamazepine-CR 589 days), Kaplan-Meier estimated proportions of patients with 12- and 24-month seizure freedom from first dose were 50.8% (95% confidence interval 46.2%-55.4%) and 47.0% (42.2%-51.7%) on lacosamide, and 54.9% (50.3%-59.6%) and 50.9% (46.0%-55.7%) on carbamazepine-CR. Incidences of drug-related TEAEs and discontinuations due to TEAEs increased by number of comorbid conditions and were lower in patients on lacosamide.. Long-term (median ~2 years) lacosamide monotherapy was efficacious and generally well tolerated in adults with newly diagnosed epilepsy. Seizure freedom rates were similar with lacosamide and carbamazepine-CR.

Long-term safety and efficacy in patients with uncontrolled partial-onset seizures treated with adjunctive lacosamide: results from a Phase III open-label extension trial.
To evaluate the long-term (up to 5 years exposure) safety and efficacy of lacosamide as adjunctive therapy in patients with uncontrolled partial-onset seizures taking one to three concomitant antiepileptic drugs (AEDs) in open-label extension trial SP756 (NCT00522275).. Patients who completed the double-blind trial SP754 (NCT00136019) were eligible to participate in this open-label extension trial (SP756). At the conclusion of trial SP754, patients had transitioned to lacosamide 200 mg/day. Subsequent dosage adjustments of lacosamide (100-800 mg/day) and/or concomitant AEDs were allowed to optimize tolerability and seizure reduction. Treatment-emergent adverse events (TEAEs), vital signs, body weight, clinical laboratory data, electrocardiography studies, and seizure frequency were evaluated.. A total of 308 patients received open-label lacosamide and 138 patients (44.8%) completed the long-term trial. The median modal dose (defined as the daily lacosamide dose a patient received for the longest duration during the treatment period) was 500 mg/day. The percentages of patients with lacosamide exposure >1, >2, >3, or >4 years were 75%, 63%, 54%, and 29%, respectively. Primary reasons for discontinuation were lack of efficacy (26%) and adverse events (11%). Common TEAEs (≥15%) were dizziness, headache, contusion, nausea, convulsion, nasopharyngitis, fall, vomiting, and diplopia. TEAEs that led to discontinuation in ≥1.0% of patients were dizziness (1.6%) and convulsion (1.0%). The median percent reductions from baseline of trial SP754 in 28-day seizure frequency were 53.4%, 55.2%, 58.1%, and 62.5%, respectively, for 1-, 2-, 3-, and 4-year completers. The ≥50% responder rates were 52.8%, 56.5%, 58.7%, and 62.5% for 1-, 2-, 3-, and 4-year completers, respectively. Seven of eight patients on lacosamide monotherapy for ≥12 months were deemed 50% responders. Of patients exposed to lacosamide ≥2 years, 3.1% remained seizure-free for a period ≥2 years.. Long-term (up to 5 years) lacosamide treatment was generally well tolerated. The safety profile of lacosamide observed in this trial is consistent with that established in previous double-blind, placebo-controlled trials. Although the open-label trial design limits the analysis of efficacy, long-term reduction in seizure frequency and maintenance of efficacy was observed.

Lacosamide as adjunctive therapy for partial-onset seizures: a randomized controlled trial.
To evaluate the efficacy and safety of lacosamide (400 and 600 mg/day) as adjunctive treatment in patients with uncontrolled partial-onset seizures taking one to three concomitant antiepileptic drugs (AEDs).. This multicenter, double-blind, placebo-controlled trial randomized patients 1:2:1 to placebo, lacosamide 400 mg, or lacosamide 600 mg/day. After an 8-week baseline period, patients began treatment with placebo or lacosamide 100 mg/day, were force-titrated weekly (100 mg/day increments) to the target dose, and entered a 12-week maintenance period.. A total of 405 patients were randomized and received trial medication. Most (82.1%) were taking two to three concomitant AEDs. Median percent reductions in seizure frequency per 28 days from baseline to maintenance (intention-to-treat, ITT) were 37.3% for lacosamide 400 mg/day (p = 0.008) and 37.8% for lacosamide 600 mg/day (p = 0.006) compared to 20.8% for placebo, with responder rates of 38.3% and 41.2%, respectively, compared to placebo (18.3%, p < 0.001; ITT). Patients randomized to lacosamide showed large reductions in secondarily generalized tonic-clonic seizures, with median percent reductions in seizure frequency of 59.4% for lacosamide 400 mg/day and 93.0% for lacosamide 600 mg/day compared to 14.3% for placebo, and responder rates of 56.0% and 70.2% compared to placebo (33.3%). Dose-related adverse events included dizziness, nausea, and vomiting.. Adjunctive treatment with lacosamide 400 and 600 mg/day reduced seizure frequency for patients with uncontrolled partial-onset seizures. Lacosamide 400 mg/day provided a good balance of efficacy and tolerability; lacosamide 600 mg/day may provide additional benefit for some patients as suggested by secondary efficacy analyses, including response in patients with secondarily generalized tonic-clonic seizures.

Long-term oral lacosamide in painful diabetic neuropathy: a two-year open-label extension trial.
This open-label follow-on trial aimed to investigate long-term safety and efficacy of lacosamide in patients with painful diabetic neuropathy.. After 1-week baseline period, lacosamide 100mg/day was started. Each week, based on pain and safety assessments, doses were escalated by 100mg/day to an optimal level, up to a maximum of 400mg/day. Patients then entered the 20-week maintenance period (dose adjusted as needed). Thereafter, patients could opt to continue lacosamide up to about 2.5 years (extension period).. Of the 69 enrolled patients, 47 (68%) completed the 20-week maintenance period and elected to continue into the extension period; 37/69 (54%) patients were in the extension period for more than one year and 34/69 (49%) continued until study termination. The modal lacosamide dose in most patients (54%) was 400mg/day. Headache, upper respiratory tract infection, arthralgia, sinusitis, nasopharyngitis, and back pain were the most frequently reported adverse events (10% of patients). Significant reductions from baseline in Likert pain scores began during dose titration and were sustained throughout the study. Significant improvements were also seen in Neuropathic Pain Scale, Quality of Life scores, and Patient's Global Impression of Change assessment. Of 34 patients at study termination, 32 (90%) elected to continue with lacosamide treatment in another long-term open-label trial (NCT00235443).. The long-term safety profile and sustained efficacy of lacosamide observed in this trial support its continued development for treatment of painful diabetic neuropathy.

Intravenous lacosamide as replacement for oral lacosamide in patients with partial-onset seizures.
This multicenter, double-blind, double-dummy, randomized, inpatient trial evaluated the safety, tolerability, and pharmacokinetics of intravenous lacosamide as replacement for oral lacosamide in patients with partial-onset seizures.. Patients were enrolled from an ongoing open-label extension trial of oral lacosamide and randomized (2:1) to either intravenous lacosamide and oral placebo or intravenous placebo and oral lacosamide. During the 2-day inpatient treatment period, patients received twice-daily doses of lacosamide equivalent to their current daily dose of oral lacosamide. The first 30 patients enrolled received infusions with 60-min durations and the next 30 received infusions with 30-min durations.. Of 60 patients randomized, 59 completed the trial. Treatment-emergent adverse events (AEs) were reported by 16 patients and included dizziness, headache, back pain, somnolence, and injection site pain. The tolerability profile of intravenous lacosamide was consistent with that of oral lacosamide. All AEs were considered mild or moderate in intensity, and no serious AEs or AEs leading to withdrawal were reported.. Intravenous lacosamide, administered as 60- or 30-min twice-daily infusions, showed a similar safety and tolerability profile to oral lacosamide when used as replacement therapy. Results from this trial support further investigation of intravenous lacosamide at shorter infusion durations.

Efficacy and safety of oral lacosamide as adjunctive therapy in adults with partial-onset seizures.
To evaluate the efficacy and safety of lacosamide when added to 1 or 2 antiepileptic drugs (AEDs) in adults with uncontrolled partial-onset seizures, and assess plasma concentrations of concomitant AEDs to determine any potential for drug interactions.. During this multicenter, double-blind, placebo-controlled trial, patients were randomized to placebo or lacosamide 200, 400, or 600 mg/day after an 8-week baseline period. Lacosamide was titrated in weekly increments of 100 mg/day over 6 weeks and maintained for 12 weeks. Results were analyzed on an intention-to-treat basis.. Four hundred eighteen patients were randomized and received trial medication; 312 completed the trial. The median percent reduction in seizure frequency per 28 days was 10%, 26%, 39%, and 40% in the placebo, lacosamide 200, 400, and 600 mg/day treatment groups, respectively. The median percent reduction in seizure frequency over placebo was significant for lacosamide 400 mg/day (p=0.0023) and 600 mg/day (p=0.0084). The 50% responder rates were 22%, 33%, 41%, and 38% for placebo, lacosamide 200, 400, and 600 mg/day, respectively. The 50% responder rate over placebo was significant for lacosamide 400 mg/day (p=0.0038) and 600 mg/day (p=0.0141). Adverse events that appeared dose-related included dizziness, nausea, fatigue, ataxia, vision abnormal, diplopia, and nystagmus. Lacosamide did not affect mean plasma concentrations of concomitantly administered AEDs.. In this trial, adjunctive lacosamide significantly reduced seizure frequency in patients with uncontrolled partial-onset seizures. Along with favorable pharmacokinetic and tolerability profiles, these results support further development of lacosamide as an AED.

Perampanel and lacosamide monotherapy in pediatric patients with newly diagnosed focal epilepsy: A prospective study evaluating efficacy, tolerability, and behavior.
Perampanel (PER) and lacosamide (LCM) are the new third-generation anti-seizure medications (ASMs) that were approved for the monotherapy of focal epilepsy in children over four years of age in China, in 2021. Very few studies have analyzed the application of PER monotherapy among pediatric patients aged ≥four years, and no study compared the efficacy and tolerability of PER monotherapy with LCM monotherapy in pediatric patients with focal epilepsy. The present study aimed to investigate the efficacy, tolerability, and effect on behavior and emotion of PER and LCM as monotherapy in pediatric patients with newly diagnosed focal epilepsy, which is beneficial for clinicians to have more choices to treat pediatric patients with focal epilepsy.. This was a prospective, single-center, observational study that involved pediatric patients (disease onset age ≥four years) with newly diagnosed focal epilepsy treated with PER or LCM as primary monotherapy. Outcomes included retention, being responders, and seizure-free rates after 3, 6, and 12 months. Adverse events (AEs) were noticed throughout the follow-up period. Behavioral outcomes were evaluated with Achenbach Child Behavior Checklist (CBCL/4-16) at baseline and after three and six months.. Using randomization, 60 patients receiving PER (31 females, 29 males, median age: 7.79 [5.34, 10.16] years, median dose: 3.0 [2.0, 4.0] mg/day) and 60 patients receiving LCM (25 females, 35 males, median age: 7.72 [5.91, 10.72] years, median dose: 150.0 [100.0, 200.0] mg/day) were enrolled in the study. At the 12-month follow-up, the retention rates in the PER and LCM groups, both were 90.4%, and the responder rates were 65.4% and 71.2%, while seizure-free rates were 57.7% and 67.3%, respectively. There were no significant differences in the retention, responder and seizure-free rates between the two groups (P > 0.05). There were no significant differences in the responder rates between patients with BECTS, abnormal brain magnetic resonance imaging (MRI), or types of seizure in the two groups (P > 0.05). In the PER group, 28.8% (15/52) of patients experienced AEs, of which the most frequently reported were irritability (n = 7; 13.5%), dizziness (n = 5; 9.6%), somnolence (n = 3; 5.8%), ataxia (n = 1; 1.9%), headache (n = 1; 1.9%), and rash (n = 1; 1.9%). In the LCM group, 15.4% (8/52) of the patients had AEs, including headache (n = 4; 7.5%), dizziness (n = 4; 7.5%), nausea (n = 2; 3.8%), somnolence (n = 2; 3.8%), irritability (n = 1; 1.9%), stomach ache (n = 1; 1.9%), and vomiting (n = 1; 1.9%). The incidence of irritability was significantly higher in the PER group than in the LCM group (13.5% vs. 1.9%, P = 0.031), which occurred mainly within eight weeks after drug administration. Patients with irritability were not dangerous to surrounding people by the assessment of parental observation in the life. And the symptoms were relieved spontaneously within a few months. The outcomes of total scores, internalizing scores, and externalizing scores of the CBCL did not show statistically significant differences in the PER and LCM groups between baseline and three and six months. Characteristics of behavior and emotion did not have substantial changes in patients treated with PER and LCM monotherapy.. The present study documented similar good effectiveness and good tolerance of PER and LCM as monotherapy in pediatric patients with newly diagnosed focal epilepsy and showed no behavioral or emotional impact, as assessed by the CBCL. Though the incidence of irritability with PER monotherapy may be higher than that with LCM monotherapy soon after medication initiation, this side effect appears to resolve spontaneously within a few months. At present, this study was the first research about PER and LCM monotherapy in pediatric patients with newly diagnosed focal epilepsy evaluating efficacy, tolerability, and behavior in China.

The effectiveness and safety of lacosamide in children with epilepsy in a clinical practice setting.
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.. To assess the effectiveness and safety of lacosamide in a population of children with mostly focal refractory epilepsy.. 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).. 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%).. 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.

Efficacy and tolerability of treatment with lacosamide: Postmarketing experience from the Middle East region.
Lacosamide (LCM) was recently introduced in the Middle East. The aim of this study was to evaluate the safety, tolerability, and efficacy of LCM in patients with focal onset seizures and determine if our results are comparable with those derived from Western countries.. This is a retrospective analysis from two medical centers on consecutive patients diagnosed as having focal onset seizures and treated with add-on LCM. The primary efficacy variables were the 50% responder and seizure-free rates, and the secondary outcome variables included the percentages of patients who achieved seizure remission during the last 6-month follow-up period and the percentages of discontinuation due to lack of efficacy or tolerability.. One hundred four patients with a mean age of 30.9 years and experiencing a mean of 9.4 seizures per month during baseline were included. The 50% responder rates were 69% and 70% at 6- and 24-month follow-ups, respectively. Patients concomitantly treated with a sodium channel blocker were less likely to achieve seizure remission during the last 6-month follow-up period while the early introduction of LCM resulted in a significantly higher likelihood of achieving such a remission. Eighty-eight percent of patients were still maintained on LCM at the last follow-up, and the most common adverse events consisted of dizziness and somnolence, double vision, and nausea/vomiting.. Our data show similar efficacy and tolerability to those reported from Western countries. Our results also substantiate the early introduction of LCM and support the dose reduction of baseline AED especially that of sodium channel blockers to minimize adverse events.

Tolerability of lacosamide or zonisamide in elderly patients with seizures.
The prevalence of seizures in the elderly will increase as populations age. Data is currently limited regarding treatment and especially tolerability of newer antiseizure medications (ASMs). In the current study we aimed to investigate the tolerability of lacosamide (LCS) and zonisamide (ZNS).. We performed a retrospective chart review of patients with seizures older than 60 treated with LCS or ZNS in the outpatient setting. We examined seizure variables, medical comorbidities, and concomitant medications. Primary outcomes were the retention rates at last follow up, and the discontinuation rate due to side effects.. Seventy-one (71) LCS and 39 ZNS patients were identified. Average age at LCS initiation was 71.0±7.0 years and 49% were medically refractory. Average duration of follow up was 23.1±21.2 months. At last follow up, the retention rate was 60% and seizure freedom rate 52%. Of the 19 discontinuations due to side effects, 7 (37%) were due to dizziness/gait instability. No predictors of discontinuation were identified. Average age at ZNS initiation was 69.7±6.9 years and 51% were medically refractory. Average duration of follow up was 46.3±38.3 months. At last follow up, the retention rate was 64% and seizure freedom rate was 67%. Of the 12 discontinuations due to side effects, 4 (33%) were due to cognitive or behavioral side effects. Predictors of discontinuation included a lower starting dose.. Lacosamide and zonisamide are viable options for the treatment of epilepsy in the elderly and have similar retention rates.
