Inclusion criteria
✓. Signed informed consent by the parent(s) or legal representative(s) and, if applicable, assent from developmentally capable pediatric subjects.
✓. Diagnosis of EECSWS.
✓. Have diagnosis of EECSWS confirmed by the Diagnosis Confirmation Panel (DCP).
✓. Stable dosage and stable time of intake of at least 1 and up to 3 antiseizure medications (ASMs) excluding systemic corticosteroids and intravenous immunoglobulin (IVIG), from 4 weeks prior to screening and anticipated to be stable from screening until end of study (EOS). Vagal nerve stimulator (VNS) and ketogenic diet are not counted as ASMs.
✓. Treatment other than ASMs (excluding systemic corticosteroids and IVIG) must be at a stable dosage from 2 weeks prior to screening and anticipated to be stable from screening until EOS.
Exclusion criteria
✕. Lennox-Gastaut syndrome, Doose syndrome (epilepsy with myoclonic-atonic seizures), or Dravet syndrome.
✕. Presence of a relevant psychiatric disease interfering with cognitive or behavioral functioning (eg, depression, schizophrenia, autism spectrum disorder) unless associated with the EECSWS diagnosis as assessed by the investigator.
✕. Presence of relevant neurological disorders other than EECSWS and its underlying conditions as judged by the investigator. Symptomatic conditions underlying EECSWS (eg, neonatal strokes) have to be stable for at least 1 year prior to screening.
✕. Body weight \<10 kg at randomization.

Ratio of Spike-Wave Index (SWI) During First Hour of Nonrapid Eye Movement (NREM) Sleep at Week 6
. Clinically relevant findings in systolic blood pressure (SBP), diastolic blood pressure (DBP), or pulse rate at screening or Day 1 as determined by the investigator.
✕. Have an average triplicate ECG corrected QT interval using Fridericia's formula (QTcF) \>450 msec or presence of any significant cardiac abnormality at screening.
✕. Clinically relevant findings in clinical laboratory tests (hematology, clinical chemistry including thyroid function parameters, and urinalysis) at screening as determined by the investigator.
✕. Have aspartate aminotransferase (AST), alanine aminotransferase (ALT), or gamma-glutamyl transferase (GGT) levels \>2 × the upper limit of normal (ULN) at screening.
