A Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of Lacosamide in Neonates With Repeated Electroencephalographic Neonatal Seizures


The purpose of the study is to evaluate the efficacy of lacosamide (LCM) versus an Active Comparator chosen based on standard of care (StOC) in severe and nonsevere seizure burden (defined as total minutes of electroencephalographic neonatal seizures (ENS) per hour) in neonates with seizures that are not adequately controlled with previous anti-epileptic drug (AED) treatment.


  • Electroencephalographic Neonatal Seizures
  • Epilepsy

Accepts Healthy Volunteers

Inclusion Criteria

  • Participant must be at least 34 weeks of gestational age (GA) - Participants who have confirmation on video-electroencephalogram (EEG) of ≥2 minutes of cumulative electroencephalographic neonatal seizures (ENS) or ≥3 identifiable ENS prior to entering the Treatment Period - Participants must have received either phenobarbital (PB), levetiracetam (LEV), or midazolam (MDZ) (in any combination) before entering the study - Participant weighs at least 2.3 kg at the time of enrollment Informed consent - An Independent Ethics Committee (IEC)-approved written informed consent form (ICF) is signed and dated by the participant's parent(s) or legal representative(s)

Exclusion Criteria

  • Participant with seizures responding to correction of metabolic disturbances (hypoglycemia, hypomagnesemia, or hypocalcemia) or with seizures for which a targeted, known treatment is available - Participant has seizures related to prenatal maternal drug use or drug withdrawal - Participant has a clinically relevant electrocardiogram (ECG) abnormality, in the opinion of the investigator - Participant receiving treatment with phenytoin (PHT), lidocaine (LDC), or other sodium channel blockers at any time

Arm Groups

ArmDescriptionAssigned Intervention
Study participants randomized to this arm will receive lacosamide (LCM) as an intravenous infusion in the Treatment Period and may continue to receive lacosamide in the Extension Period. Participants should be switched to oral dosing of LCM as soon as medically possible during the Extension Period.
  • Drug: Lacosamide intravenous
    Study participants will receive lacosamide (LCM) as an intravenous (iv) infusion during the Treatment Period.
    Other names:
    • LCM
  • Drug: Lacosamide oral
    Study participants may receive lacosamide (LCM) as an oral solution during the Extension Period.
    Other names:
    • LCM
Active Comparator
Active Comparator
Study participants randomized to this arm will receive Active Comparator chosen based on standard of care (StOC) in the Clinical Practice in the Treatment Period and may continue to receive in the Extension Period.
  • Other: Active Comparator
    Active Comparator treatment will be chosen and dosed based on StOC (per local practice and treatment guidelines).
