Study Endpoints

Primary Endpoints

Percentage of Participants who Experience at Least One Treatment Emergent Adverse Event (TEAE)
Up to approximately 43 days

An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as an AE with an onset that occurs after receiving study drug.

Percentage of Participants who Meet the Markedly Abnormal Criteria for Clinical Safety Laboratory Tests at Least Once Post a Regimen
Up to approximately 43 days

Clinical laboratory evaluations include hematology, blood chemistry, and urinalysis.

Percentage of Participants who Meet the Markedly Abnormal Criteria for Vital Sign Measurements at Least Once Post a Regimen
Up to approximately 43 days

Vital signs include heart rate, respiratory rate, systolic blood pressure (SBP) and diastolic blood pressure (DBP).

Percentage of Participants who Meet the Markedly Abnormal Criteria for 12-Lead Safety Electrocardiogram (ECG) Parameters at Least Once Post a Regimen
Up to approximately 43 days

A standard 12-lead ECG will be performed.

Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs)
From the first dose of study drug up to 7 days after the last dose of study drug (up to Day 15)

An Adverse Event (AE) was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE was defined as an AE with an onset that occurs after receiving study drug.

Latency to Sleep Onset on Maintenance of Wakefulness Test (MWT) at 2 Hours Post-infusion Start
Day 1: 2 hours post-infusion start

The MWT is a validated objective measure that evaluates a person's ability to remain awake under soporific conditions for a defined period of time. This tendency to fall asleep is measured via electroencephalography-derived sleep latency. Sleep onset is defined as the first epoch of greater than 15 seconds of cumulative sleep in a 30-second epoch. Trials were ended after 40 minutes if no sleep occurs, or after unequivocal sleep, defined as 3 consecutive epochs of stage 1 sleep, or 1 epoch of any other stage of sleep. If no sleep has been observed according to these rules, then the latency is defined as 40 minutes. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake.

Latency to Sleep Onset on MWT at 4 Hours Post-infusion Start
Day 1: 4 hours post-infusion start

The MWT is a validated objective measure that evaluates a person's ability to remain awake under soporific conditions for a defined period of time.

Sleep onset is defined as the first epoch of greater than 15 seconds of cumulative sleep in a 30-second epoch. Trials were ended after 40 minutes if no sleep occurs, or after unequivocal sleep, defined as 3 consecutive epochs of stage 1 sleep, or 1 epoch of any other stage of sleep. If no sleep has been observed according to these rules, then the latency is defined as 40 minutes. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake.

Latency to Sleep Onset on MWT at 6 Hours Post-infusion Start
Day 1: 6 hours post-infusion start

The MWT is a validated objective measure that evaluates a person's ability to remain awake under soporific conditions for a defined period of time. This tendency to fall asleep is measured via electroencephalography-derived sleep latency. Sleep onset is defined as the first epoch of greater than 15 seconds of cumulative sleep in a 30-second epoch. Trials were ended after 40 minutes if no sleep occurs, or after unequivocal sleep, defined as 3 consecutive epochs of stage 1 sleep, or 1 epoch of any other stage of sleep. If no sleep has been observed according to these rules, then the latency is defined as 40 minutes. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake.

Latency to Sleep Onset on MWT at 8 Hours Post-infusion Start

Trials were ended after 40 minutes if no sleep occurs, or after unequivocal sleep, defined as 3 consecutive epochs of stage 1 sleep, or 1 epoch of any other stage of sleep. If no sleep has been observed according to these rules, then the latency is defined as 40 minutes. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake.

Latency to Sleep Onset on MWT at 1 Hour Post-end of Infusion
Day 1: 1 hour post-end of infusion
