    Co-Authors: Yoko Ohtsuka, Harumi Yoshinaga, Rumiko Takayama, Hiroki Takano, Yukiyoshi Shirasaka, Kuniaki Iyoda
    Abstract:

    Summary Purpose To evaluate the efficacy, safety, and pharmacokinetics of rufinamide as an adjunctive therapy for patients with Lennox–Gastaut syndrome (LGS) in a randomized, double-blind, placebo-controlled trial. Methods We conducted a multicenter clinical trial with a 4-week baseline, a 2-week titration, a 10-week maintenance, and either a follow-up visit or entry into an open-label extension. Patients with LGS (4 to 30 years old) taking between one and three antiepileptic drugs were recruited. After the baseline period, patients were randomly assigned to rufinamide or placebo. The primary efficacy variable was the percent change in the tonic–Atonic Seizure frequency per 28 days. Key findings Of the 59 patients, 29 were randomized to the rufinamide group and 30 to the placebo group. The frequency of epileptic Seizures was significantly decreased in the rufinamide group than in the placebo group; the median percent change in frequency of tonic–Atonic Seizures was −24.2% and −3.3%, respectively, ( p =0.003) and that of total Seizures was −32.9% and −3.1%, respectively ( p Significance The present results showed a favorable risk-benefit profile for rufinamide as an adjunctive therapy for patients with LGS.

    Neurology, 2018
    Co-Authors: Alexis Arzimanoglou, Yoko Ohtsuka, Carlos Perdomo, Betsy Williams, G Kluger, Francesco Bibbiani, A Muller, Manoj Malhotra
    Abstract:

    Objective: Present an overview of efficacy and safety for adjunctive rufinamide in LGS patients aged 1–30 years. Background: LGS, a rare epilepsy syndrome, affects 1–4% of children with epilepsy. Limited treatment options demonstrate inadequate Seizure control and unfavorable tolerability. Design/Methods: Studies 022 (Glauser et al. Neurology 2008;70:1950–1958) and 304 (Ohtsuka et al. Epilepsy Res 2014;108:1627–1636) were Phase III, double-blind, placebo-controlled studies of adjunctive rufinamide in LGS patients aged 4–30 years (28-day Baseline; 84-day Treatment Phase). Rufinamide maintenance dose: 022, ≤45 mg/kg/day; 304, 800–3200 mg/day by body weight (15.0 to ≥70.1 kg). Patients completing 022 or 304 could enter an open-label extension (022E [Kluger et al. Acta Neurol Scand 2010;122:202–208]; 305 [Ohtsuka et al. Epilepsy Res 2016;121:1–7], respectively). The Phase III, randomized, open-label Study 303 (Arzimanoglou et al. EJPN 2016;20:393–402) assessed adjunctive rufinamide (45 mg/kg/day) versus any-other-AED (antiepileptic drug) in patients aged 1– Results: Median percent reduction in tonic-Atonic Seizure frequency: 022, 42.5% rufinamide (n=74) and −1.4% placebo (n=64; P P =0.003). Median percent reduction in total Seizure frequency: 022, 32.7% rufinamide and 11.7% placebo ( P =0.0015); 304, 32.9% and 3.1%, respectively ( P Conclusions: There were significant reductions in Seizure frequencies for adjunctive rufinamide versus placebo in LGS patients aged 4–30 years.

  • adjunctive rufinamide in lennox gastaut syndrome a long term open label extension study
    Acta Neurologica Scandinavica, 2010
    Co-Authors: Gerhard Kluger, Tracy A Glauser, Gregory Krauss, R Seeruthun, Carlos Perdomo, S Arroyo
    Abstract:

    Kluger G, Glauser T, Krauss G, Seeruthun R, Perdomo C, Arroyo S. Adjunctive rufinamide in Lennox-Gastaut syndrome: a long-term, open-label extension study. Acta Neurol Scand: 122: 202–208. © 2010 The Authors Journal compilation © 2010 Blackwell Munksgaard. Objective –  This open-label extension evaluated the long-term efficacy and tolerability of rufinamide in patients with Lennox-Gastaut syndrome (LGS) who had previously completed a 12-week double-blind study. Materials and methods –  In total, 124 patients (aged 4–37 years), receiving 1–3 concomitant antiepileptic drugs, were treated with rufinamide ∼25–60 mg/kg/day. Efficacy was assessed by Seizure frequency; tolerability by adverse events (AEs) and laboratory tests. Results –  Overall, patients were treated with rufinamide for a median (range) of 432 (10–1149) days. Reductions in Seizure frequency were observed throughout the study; during the last 12 months of treatment, 41.0% and 47.9% of patients had ≥50% reduction in total and tonic–Atonic Seizure frequency, respectively. The most common AEs were vomiting (30.6%) and pyrexia (25.8%). Conclusions –  In this open-label extension, rufinamide appeared to be an effective long-term adjunctive therapy for the treatment of LGS-associated Seizures in children and young adults.

  • Partial Epilepsy Manifesting Atonic Seizure: Report of Two Cases
    Epilepsia, 2002

    Abstract:

    Summary:  Purpose: Atonic Seizures are commonly seen in patients with generalized epilepsy but only infrequently in patients with partial epilepsy. Clinically generalized Atonic Seizures as a partial epilepsy have not been studied in detail with video/EEG monitoring. Here we describe the clinical and physiologic characteristics of Atonic Seizures due to partial epilepsy and discuss the underlying mechanism. Methods: Two patients with partial epilepsy manifesting Atonic Seizures, one with frontal lobe epilepsy (FLE) and the other with parietal lobe epilepsy (PLE), were reported. The long-term video/EEG monitoring, magnetic resonance imaging (MRI), and interictal fluorodeoxyglucose–positron emission tomography (FDG-PET) were investigated in each patient. Results: Paroxysmal diminution of muscle tone mainly involved the axial muscles in both patients. In contrast with the abrupt falls seen in patients with Lennox–Gastaut syndrome, the falls in these patients were slow, taking 2–5 s to fall down. Ictal EEG records showed low-voltage fast activity in the frontocentral area followed by repetitive spikes at the midline frontocentral area in the patient with FLE, and rhythmic spikes in the left central area in the patient with PLE. Interictal FDG-PET disclosed hypometabolic regions consistent with the clinical and EEG findings. Conclusions: Slow falls might be a feature of Atonic Seizures in partial epilepsy. Long-lasting atonia in partial epilepsy could be due to either one of the following two possible mechanisms: (a) epileptic activities arising from the negative motor area, of which 50-Hz electric stimulation causes motor inhibition, or (b) sustained atonia with successive electromyogram (EMG) silent periods caused by epileptic discharges arising from the inhibitory area of the primary sensorimotor area.
