Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | SAGE-547 | 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. | 38 | 66 | OG001 |
| Group 2 | Placebo | Placebo was administered over the course of 6 days, beginning with a 1-hour dose rate equivalent to 300 micrograms per kilogram per hour (μg/kg/h) of the active arm loading dose, followed by a maintenance period achieving a maximum of 90 μg/kg/h (double-blind treatment), which included a step-wise taper during the last 24 hours of treatment. | 45 | 66 | OG000 |

Outcome
- Type
- SECONDARY
- Title
- Number of Participants Able to be Weaned Off All Third-line Agents Before the End of the First SAGE-547 or Placebo Infusion
- Description
Third-line agents were anesthetic agents that were administered in order to reach a seizure or burst suppression 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.
- Time frame
- Day 6
- Population
- The Intent-to-Treat Analysis Set included all participants who had an infusion of blinded study drug initiated.
