    Inclusion Criteria:

    1. Subject is willing and able to provide 2 forms of identification; at least 1 must have a photo.
    2. Subject has a body weight ≥50 kg and body mass index ≥18.0 and ≤30.0 kg/m2 at screening.

    3. Subject has a family history of epilepsy.
    4. Subject has evidence of any metal in the body that may be contraindicated for receiving an MRI. This includes, but is not limited to: cardiac pacemaker, surgical implants, previous accident resulting in metal or shrapnel lodged internally, tattoos inked with metallic dyes, or a history of metal work without using protective eyewear.
    5. Subject has claustrophobia or a history of claustrophobia.
    6. Subject is unable or unwilling to remove piercings and/or jewelry that contain metal.

    Primary Outcomes
    • Change in glutamate and glutamine (GLX) in the anterior cingulate cortex (ACC), hippocampus, and pons as measured with magnetic resonance spectroscopy (MRS) Between Day 1 and Day 11
    Secondary Outcomes
    • Change in glutamate in the ACC, hippocampus, and pons, as measured with MRS Between Day 1 and Day 11
    • Safety and tolerability of SAGE-718 alone and in combination with ketamine, as assessed by incidence of adverse events (AEs)/serious AEs (SAEs) Between Baseline and Day 27
    • Observed values and change from baseline in EEGs in patients post study drug administration

    • Observed values and change from baseline in ECGs in patients post study drug administration

    • Safety and tolerability of SAGE-718 alone and in combination with ketamine, as assessed by Columbia-Suicide Severity Rating Scale (C-SSRS) Between Baseline and Day 27
    • Safety and tolerability of SAGE-718 alone and in combination with ketamine, as assessed by Brief Psychiatric Rating Scale (BPRS) Between Baseline and Day 27
    • Safety and tolerability of SAGE-718 alone and in combination with ketamine, as assessed by Clinician Administered Dissociative State Scale (CADSS) Between Baseline and Day 27
    • Safety and tolerability of SAGE-718 alone and in combination with ketamine, as assessed by Observer's Assessment of Alertness and Sedation (OAAS) Between Baseline and Day 27
