MARLBOROUGH, Mass.
Sunovion Pharmaceuticals Inc. (Sunovion) is presenting new findings from sub-analyses of the pooled Phase 3 studies (Studies 301, 302 and 304) evaluating the safety and efficacy of Aptiom® (eslicarbazepine acetate) as adjunctive treatment of partial-onset seizures. These presentations at the 66th American Academy of Neurology (AAN) Annual Meeting (April 26 – May 3, Philadelphia) continue to demonstrate the importance of new treatment options for partial-onset seizures, such as APTIOM.
“APTIOM has been well-received by healthcare professionals since its recent market introduction in the United States. The APTIOM data presented at AAN support the efficacy and safety profile that led to its FDA approval for use as adjunctive treatment for partial-onset seizures,” said Fred Grossman, D.O., FAPA, Senior Vice President, Clinical Development and Medical Affairs at Sunovion.
APTIOM, a voltage-gated sodium channel blocker, is now available by prescription in pharmacies across the United States. Recognized as a new molecular entity by the U.S. Food and Drug Administration (FDA), APTIOM was approved on November 8, 2013, for use as adjunctive treatment of partial-onset seizures.1
Thirteen Sunovion-supported analyses will be presented at this year’s AAN Annual Meeting, including eight regarding APTIOM and five presentations of new healthcare economics and outcomes research in epilepsy.
APTIOM Poster Presentations
Poster Session III – Epilepsy and Clinical Neurophysiology: AED – Tuesday, April 29, 2014, from 3:00 p.m. EDT until 6:30 p.m. EDT
Poster 3.239 – Efficacy of Eslicarbazepine Acetate in Patients with Refractory Partial-Onset Seizures Treated With or Without Concomitant Carbamazepine: A Pooled Analysis of Three Phase III Controlled Studies
The efficacy analysis of the pooled Phase 3 APTIOM studies demonstrated that both APTIOM 800 mg and 1,200 mg once-daily for the adjunctive treatment of partial-onset seizures were efficacious in reducing standardized seizure frequency (SSF) among treatment-resistant epilepsy patients with partial-onset seizures, with or without concomitant carbamazepine use [-CBZ: 7.5 vs. 5.7 (p=0.01), 4.9 (p<0.0001); +CBZ: 8.0 vs. 6.5 (p<0.05), 6.6 (p<0.05)]. The data suggest that the efficacy of APTIOM is similar with and without the concomitant use of carbamazepine, an antiepileptic drug with a proposed mechanism of action similar to that of APTIOM.
Poster 3.237 – Safety of Eslicarbazepine Acetate in Patients with Refractory Partial-Onset Seizures Treated With or Without Concomitant Carbamazepine: A Pooled Analysis of Three Phase III Controlled Studies
Findings from the pooled APTIOM Phase 3 studies’ safety analysis in patients treated with or without carbamazepine suggest that some adverse events were more frequent in patients using concomitant carbamazepine. Results demonstrated dizziness (800 mg: 15.9% vs. 4.9%; 1,200 mg: 26.2% vs. 11.5%), diplopia (800 mg: 11.7% vs. 2.0%; 1,200 mg: 13.2% vs. 4.5%), vomiting (800 mg: 6.3% vs. 0.6%; 1,200 mg: 9.7% vs. 5.1%) and nausea (800 mg: 5.2% vs. 3.7%; 1,200 mg: 13.0% vs. 7.7%) were more frequent, and somnolence (1,200 mg: 4.1% vs. 14.8%) and tremor (1,200 mg: 0% vs. 6.9%) were less frequent.

- Poster 6.180 – Impact of Seizure Frequency Reduction on Health-Related Quality of Life Among Clinical Trial Subjects with Refractory Partial-Onset Seizures: A Pooled Analysis of Phase III Clinical Trials of Eslicarbazepine Acetate
About APTIOM Phase 3 Studies 301, 302 and 304
Studies 301, 302 and 304 were Phase 3 randomized, double-blind, placebo-controlled safety and efficacy trials of similar study design, involving more than 1,400 patients with partial-onset seizures inadequately controlled by one to three concomitant antiepileptic drugs (AEDs) (including carbamazepine, lamotrigine, valproic acid and levetiracetam) to evaluate the safety and efficacy of APTIOM for the adjunctive treatment of partial-onset seizures. The primary endpoint for all three studies was the standardized seizure frequency per four weeks during the maintenance phase. Secondary endpoints included relative change in seizure frequency from baseline and responder rates (percent of patients with ≥50 percent or ≥75 percent seizure reduction). Results demonstrated the safety and efficacy of APTIOM as an adjunctive therapy of partial-onset seizures. The FDA approval of APTIOM was supported by the findings of these pivotal studies.
About Partial-Onset Seizures
Epilepsy is one of the most common neurological disorders and affects nearly 2.2 million people in the United States.2 Epilepsy is characterized by abnormal firing of impulses from nerve cells in the brain.3 Partial-onset seizures are the most prevalent seizure type, accounting for approximately 60 percent of new epilepsy diagnoses.4 In partial-onset seizures, bursts of electrical activity are initially focused in specific areas of the brain, but may become more widespread, with symptoms varying according to the affected areas.5,6 The unpredictable nature of seizures can have a significant impact on those with epilepsy, affecting a number of areas of daily living, including education, employment, driving and recreation.2 Reducing the frequency of seizures can greatly lessen the burden of epilepsy.2
About APTIOM
APTIOM, a voltage-gated sodium channel blocker, is a prescription medicine approved for use as adjunctive treatment of partial-onset seizures. APTIOM is available in four tablet strengths (200 mg, 400 mg, 600 mg and 800 mg), which can be taken whole or crushed, with or without food.
The safety and efficacy of APTIOM was established in three Phase 3 randomized, double-blind, placebo-controlled trials of more than 1,400 people living with partial-onset seizures inadequately controlled by one to three concomitant AEDs (including carbamazepine, lamotrigine, valproic acid and levetiracetam). These studies showed that treatment with APTIOM demonstrated statistically significant reductions in standardized seizure frequency versus placebo, and more APTIOM treated patients experienced seizure frequency reduction of 50 percent or more from baseline (41% compared to 22% for placebo-treated patients). The most common side effects in patients taking APTIOM included dizziness, sleepiness, nausea, headache, double vision, vomiting, feeling tired, problems with coordination, blurred vision and shakiness.
Sunovion acquired the rights under an exclusive license to further develop and commercialize eslicarbazepine acetate in the United States and Canadian markets from BIAL-Portela & Ca, S.A. (BIAL), a privately held Portuguese research-based pharmaceutical company. BIAL conducted the initial research and development of eslicarbazepine acetate and, in April 2009, received approval from the European Commission for the use of eslicarbazepine acetate as adjunctive therapy in adult patients with partial-onset seizures with or without secondary generalization. In Europe, the product is marketed under the trade name Zebinix®.
