15. Status epilepticus
16. Pregnancy

21. Any major neurological or psychiatric disorder associated with significant impairment of cognitive function or motor function e.g., Alzheimer’s disease with dementia, Parkinson’s disease, Huntington’s disease, alcohol or substance abuse
22. Participating in or has participated in other investigational interventional studies (drug or device) within the last 30 days (or 5 times the half-life of the previously administered investigational compound, whichever is longer) prior to study treatment initiation
