- Secondary Outcome Measures
Name Time Method Cmax: Maximum Observed Plasma Concentration for ORX142 in subjects receiving ORX142 Pre-dose and multiple post-dose timepoints, up to 48 hours Tmax: Time of Maximum Concentration for ORX142 in subjects receiving ORX142 Pre-dose and multiple post-dose timepoints, up to 48 hours Tmax: Time of Maximum Concentration for ORX142 in subjects receiving ORX142 in the fast and fed state Pre-dose and multiple post-dose timepoints, up to 48 hours AUClast: Area Under the Plasma Concentration-time Curve From Time 0 to the Time of the Last Quantifiable Concentration for ORX142 in subjects receiving ORX142 Pre-dose and multiple post-dose timepoints, up to 48 hours T 1/2 (terminal elimination half-life): The time required for the terminal phase blood concentration of ORX142 to decrease by half in subjects receiving ORX142 Pre-dose and multiple post-dose timepoints, up to 48 hours AUClast: Area Under the Plasma Concentration-time Curve From Time 0 to the Time of the Last Quantifiable Concentration for ORX142 in subjects receiving ORX142 in the fast and fed state Pre-dose and multiple post-dose timepoints, up to 48 hours T 1/2 (terminal elimination half-life): The time required for the terminal phase blood concentration of ORX142 to decrease by half in subjects receiving ORX142 in the fast and fed state Pre-dose and multiple post-dose timepoints, up to 48 hours Mean sleep latency in the Maintenance of Wakefulness Test (MWT) for ORX142 versus placebo. Part E: Day 2 Cmax: Maximum Observed Plasma Concentration for ORX142 in subjects receiving ORX142 in the fasted and fed state.
