| Number of Participants Able to be Weaned Off All Third-Line Agents Prior to End of Double-Blind SAGE-547 or Placebo Infusion, and Remain Off All Third-Line Agents for ≥ 24 Hours Following the End of SAGE-547 or Placebo Infusion | Third-line agents were anesthetic agents that were administered in order to reach a seizure or burst suppression electroencephalogram (EEG) pattern. For this study, third-line agents were defined as continuous intravenous infusions of pentobarbital/thiopental, midazolam, propofol, and ketamine at maintenance doses alone or in combination sufficient to produce a burst or seizure suppression pattern on the EEG. A responder was a participant who was able to be weaned off all third-line agents prior to the end of the SAGE-547 or placebo infusion and remain off all third-line agents for >=24 hours after the end of the study drug infusion. The primary analysis was a comparison between SAGE-547 and placebo of the proportion of responders. | 7 days |

Participants 2 years of age and older with Super-Refractory Status Epilepticus were eligible. One participant in the placebo group was erroneously given SAGE-547 and was, therefore, included in the SAGE- 547 group.
Participants took part in the study at 122 investigative sites in Canada, United States, Austria, Denmark, Estonia, Finland, France, Germany, Israel, Italy, Serbia, Spain and United Kingdom from 31 July 2015 to 11 August 2017.

| Change in Clinical Global Impression Scale (CGI) | The CGI scale was used to integrate several sources of information into a single rating of a participant's condition. The CGI was rated on a 7-point scale, from a minimum of 0 to a maximum of 7, where 0 = Not assessed; 1 = Normal, not at all ill; 2 = Borderline physically ill; 3 = Mildly ill; 4 = Moderately ill; 5 = Markedly ill; 6 = Severely ill; 7 = Among the most extremely ill participants. A negative change from baseline indicates improvement. A positive change from baseline indicates worsening. Here, study visits followed by "R" indicate the Open-label Treatment Period. | Up to 21 days |

SAGE-547 Injection was administered over the course of 6 days, beginning with a 1-hour 300 μg/kg/h loading dose, followed by a maintenance period achieving a maximum of 90 μg/kg/h (double-blind treatment) or 150 μg/kg/h (open-label treatment), both of which included a step-wise taper during the last 24 hours of treatment. Eligible participants, who did not respond to blinded study treatment, were allowed to enter an Open-label Treatment Period of identical duration. |
