Brief summary
SP942 is a non-interventional post-authorization safety study (PASS) to evaluate the long-term safety and tolerability of Vimpat® (Lacosamide, LCM) as add-on treatment in patients with Epilepsy 16 years and older with partial-onset seizures who are uncontrolled on current therapy. Using reported adverse events, the incidence of certain cardiovascular and psychiatric events will be evaluated.
Interventions
Vimpat was used as per site routine practices, and in-line with the marketing authorization.

| The Incidence of Predefined Cardiovascular Treatment-Emergent Adverse Events (TEAEs) in Epilepsy Patients With Partial-onset Seizures While on Vimpat or Any Other add-on Antiepileptic Drug (AED) Treatment During the Study | From Baseline up to 12 months | Predefined cardiovascular-related Adverse Events (AEs), ie, Atrioventricular (AV) block, syncope, bradycardia, and PR prolongation, were identified as AEs coded to one of the following MedDRA Preferred Terms: Adams-Stokes syndrome, Atrioventricular block, Atrioventricular block complete, Atrioventricular block first degree, Atrioventricular block second degree, Syncope, Bradycardia, Bradyarrhythmia, Sinus bradycardia, or Electrocardiogram PR prolongation. Treatment-emergent Adverse Events (TEAEs) are those that start on or after the day of first intake of the add-on AED treatment and up to 30 days after the day of last add-on AED treatment intake. |

Participant flow
Recruitment details
Patients were enrolled into 1 of 2 groups in this study (500 unique patients per group) at the discretion of the treating physician: patients treated with Vimpat as add-on to their current Anti-Epileptic Drug (AED) therapy (group 1) and patients treated with other approved AEDs as add-on (group 2).
Pre-assignment details
Patient procedures and assessments were performed in the frame of the current standard practice at the discretion of the treating physician. Each patient was followed for the initial 12 months of add-on AED treatment. A Safety Follow-Up Visit is recommended for any patient who terminates add-on AED treatment before the end of the study period.

Outcome results
The Incidence of Predefined Cardiovascular Treatment-Emergent Adverse Events (TEAEs) in Epilepsy Patients With Partial-onset Seizures While on Vimpat or Any Other add-on Antiepileptic Drug (AED) Treatment During the Study
Predefined cardiovascular-related Adverse Events (AEs), ie, Atrioventricular (AV) block, syncope, bradycardia, and PR prolongation, were identified as AEs coded to one of the following MedDRA Preferred Terms: Adams-Stokes syndrome, Atrioventricular block, Atrioventricular block complete, Atrioventricular block first degree, Atrioventricular block second degree, Syncope, Bradycardia, Bradyarrhythmia, Sinus bradycardia, or Electrocardiogram PR prolongation. Treatment-emergent Adverse Events (TEAEs) are those that start on or after the day of first intake of the add-on AED treatment and up to 30 days after the day of last add-on AED treatment intake.
