Trial Outcomes & Findings for Study to Assess the Long-term Safety of Oral Lacosamide in Subjects With Partial-onset Seizures (NCT NCT00655486)

NCT ID: NCT00655486

Last Updated: 2018-07-17

Results Overview

An Adverse Event (AE) is any untoward medical occurrence (eg, noxious or pathological changes) in a subject or clinical investigation subject compared with pre-existing conditions, that occurs during any period of a clinical trial including Pre-treatment, Run-In, Wash-Out, or Follow-Up Periods. An AE is defined as being independent of assumption of any causality (eg, to study or concomitant medication, primary or concomitant disease, or study design).
