- Simulated driving performance as measured by SDLP using the CRCDS-MiniSim for rapastinel compared with placebo and positive control (alprazolam) [ Time Frame: Day 1 of each intervention ]
- simulated driving performance as measured by SDLP using the CRCDS-MiniSim for rapastinel compared with a clinical comparator (ketamine) [ Time Frame: Day 1 of each intervention ]
- Karolinska Sleepiness Scale (KSS) [ Time Frame: Day 1 of each intervention ]The KSS is a participant self-reported measure of situational sleepiness and provides an assessment of alertness/sleepiness. The KSS is a 9-point categorical scale, where 1 = "extremely alert" and 9 = "extremely sleepy-fighting sleep".
- Self-perceived safety to drive ("Right now do you feel safe to drive?) [ Time Frame: Day 1 of each intervention ]
- Visual Analog Scale to assess participant's motivation and self-appraisal of their driving performance [ Time Frame: Day 1 of each intervention ]
- CogScreen SDC Test [ Time Frame: Day 1 of each intervention ]
- Proportion of abnormal lane exceedance events [ Time Frame: Day 1 of each intervention ]
- Average Speed (mph) [ Time Frame: Day 1 of each intervention ]
- Total collisions [ Time Frame: Day 1 of each intervention ]
- Number of exceeded cornering speed threshold events [ Time Frame: Day 1 of each intervention ]
- Divided attention: average number of correct responses [ Time Frame: Day 1 of each intervention ]Participants are asked to answer periodic questions during the driving simulation.
- Divided attention: average number of errors [ Time Frame: Day 1 of each intervention ]Participants are asked to answer periodic questions during the driving simulation.
- Divided attention: average reaction time [ Time Frame: Day 1 of each intervention ]
- Rapastinel blood plasma concentration [ Time Frame: Day 1 of each intervention ]
- Adverse Events [ Time Frame: Up to 66 days ]
- Proportion of abnormal electrocardiograms [ Time Frame: Up to 66 days ]
- Columbia-Suicide Severity Rating Scale [ Time Frame: Up to 66 days ]The C-SSRS is a clinician-ratedinstrument that reports theseverity of both suicidal ideation and behavior. Suicidal ideation is classified on a 5-item scale: 1 (least severe) to 5 (most severe).
