Sunovion Announces Results of Health Outcomes Analyses Exploring the Effectiveness of Aptiom® (eslicarbazepine acetate) in People with Partial-Onset Seizures
In
A post-hoc pooled analysis of two historical-controlled Phase 3 APTIOM monotherapy clinical trials (Studies 093-045 and 093-046) showed that patients with partial-onset seizures who achieved a clinical response after converting from a multi-AED regimen to APTIOM monotherapy experienced quality of life improvements after 10 weeks. A separate analysis of these studies also showed that patients with partial-onset seizures experienced statistically and clinically significant improvements in depressive symptoms after 10 weeks, following successful conversion from their current AED regimen to APTIOM monotherapy.
During AES, Sunovion also presented an analysis from the IMS PharMetrics Plus database. The results indicated that, after controlling for baseline confounders, patients initiating AED therapy with one pill/day had fewer annual hospitalizations and emergency room visits than initiating AED therapy with two or more pills/day.
“Seizures account for one million emergency department visits every year, and epilepsy has significant impacts on a person’s ability to drive or maintain employment,” said

Quality of Life Improvement among Patients with Refractory Partial-Onset Seizures: A Clinical Trial Analysis of Patients who Responded to Eslicarbazepine Acetate Monotherapy (Poster 1.182, Presented
Pooled data from two historical-controlled Phase 3 studies (093-045 and 093-046) evaluated patients who had completed 10 weeks of APTIOM monotherapy (n=224) for change in health-related quality of life, using Quality of Life in Epilepsy-31 (QOLIE-31) questionnaire. The QOLIE-31 is an instrument that assesses daily functioning and overall well-being in patients with epilepsy. The mean change in QOLIE-31 Total Score and seven subscale scores from baseline to Week 18 were compared to standard minimal clinically-important difference (MCID) change scores. The results showed that the mean change in QOLIE-31 Total Score and five of the seven subscales (Medication Effects, Seizure Worry, Social Functioning, Overall Quality of Life, Cognitive Functioning, and Energy/Fatigue) were greater than their respective MCIDs; these changes were statistically significant for Medication Effects (p=0.011), and Social Functioning (p=0.008).
Change in Depressive Symptoms Among Patients With Refractory Partial-Onset Seizures Treated With Eslicarbazepine Acetate Monotherapy: A Pooled Analysis of Clinical Trials (Poster 2.249, Presented
Pooled data from two historical-controlled Phase 3 studies (093-045 and 093-046) evaluated patients who had completed 10 weeks of APTIOM monotherapy (Completers, n=224), as well as a subset of these patients who achieved a clinical response after 10 weeks of treatment (Responders, n=117), for change in depressive symptoms, using the
Data showed that mean change in the MADRS scores was significantly decreased (indicating a reduction in depressive symptoms) and exceeded published MCID change scores (-2.1 for Completers and -2.6 for Responders, p<0.001 for both). Over half of all patients in these groups (56.3 percent of Completers and 56.4 percent of Responders) experienced significant reductions in depressive symptoms—with most patients (90.5 percent and 87.9 percent, respectively) reporting decreased MADRS scores of two or more points.
The Association Between Antiepileptic Drug Pill Burden at Monotherapy Initiation and Epilepsy-Related Hospital Admissions and Emergency Department Visits in the US (Poster 2.282, Presented
A retrospective analysis of health insurance claims data from more than 53,000 epilepsy patients who initiated AED monotherapy found that patients who initiated with a one pill/day regimen had fewer hospitalizations and emergency room visits over the following 12 months compared with patients initiating with two or more AEDs. Patients initiating with two, three, or more than three pill/day regimens had annual hospitalization rates that were 12.5, 23.1, and 19.4 percent higher respectively, compared to patients taking one pill/day. Patients initiating with larger pill burdens also had significantly higher rates of emergency room visits during the year of following-up (15.5 , 25.2, and 15.1 percent higher for patients taking two, three, or more than three pills/day, respectively).
About the Phase 3 Monotherapy Studies
Two identically designed Phase 3, dose-blinded, historical-controlled, multi-center, randomized clinical trials (Studies 093-045 and 093-046) evaluated the safety and efficacy of APTIOM (1,600 mg/day or 1,200 mg/day) as monotherapy for partial-onset seizures in patients 16 years of age or older whose seizures were not well-controlled with other antiepileptic drugs (AEDs).
The primary endpoint for both trials was the percentage of patients who exited the study due to pre-defined criteria identifying worsening seizure control, compared to historical controls from previous, similarly designed trials of epilepsy patients converting to AED monotherapy. Trial results showed that conversion to APTIOM monotherapy was associated with exit rates superior to historical controls in patients with partial-onset seizures, who were not well-controlled by one or two current AEDs.
APTIOM administered once-daily was generally well tolerated in both dose strengths. In the APTIOM monotherapy trials, the most common treatment-related adverse events, headache, dizziness, fatigue, somnolence, and nausea, were mainly mild or moderate in severity.

About Epilepsy and Partial-Onset Seizures
Epilepsy is the fourth most common neurological condition, and one in 26 people in the U.S. will develop epilepsy in his or her lifetime.i Epilepsy manifests as unprovoked seizures, which are caused by abnormal firing of impulses from nerve cells in the brain.ii Partial-onset seizures, the most common type of seizure, are characterized by bursts of electrical activity that are initially focused in specific areas of the brain and may become more widespread, with symptoms varying according to the affected areas.iii The unpredictable nature of seizures may have a significant impact on those with epilepsy. Reducing the frequency of seizures may lessen the burden of epilepsy.ii With approximately one-third of people living with epilepsy still unable to control seizures, there continues to be a need for new therapies.iv Up to 40 percent of people living with epilepsy do not respond to the first or second monotherapyv, and approximately 36 percent fail to achieve adequate control of seizures despite the use of two or more antiepileptic medicationsvi.
Please see Important Safety Information below.
INDICATION:
Aptiom® (eslicarbazepine acetate) is a prescription medicine used alone or with other medicines to treat partial-onset seizures.
