What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Apnea-Hypopnea Index (AHI)
Time Frame: Day 4
|
Evaluation of the effect of multiple dose administration of suvorexant on AHI as measured by polysomnography. The AHI is an overall index of obstructive sleep apnea (OSA) severity. The AHI is calculated by dividing the number of apneas and hypopneas by the number of hours of sleep. AHI values are categorized as mild OSA = 5 to <15/hr and moderate OSA = 15 to <30/hr. |
Day 4
|
Number of Participants With an Adverse Event
Time Frame: Up to 14 days after last dose
|
An adverse event (AE) is any unfavorable and unintended change in the structure, function or chemistry of the body temporally associated with study drug administration whether or not considered related to the use of the product.
|
Up to 14 days after last dose
|
Number of Participants Who Discontinued Study Drug Due to an AE
Time Frame: Up to 13 days
|
An AE is any unfavorable and unintended change in the structure, function or chemistry of the body temporally associated with study drug administration whether or not considered related to the use of the product.
|
Up to 13 days
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Arterial Oxygen Saturation (SaO2) During Total Sleep Time
Time Frame: Day 1 and Day 4
|
Evaluation of the effect of multidose dose suvorexant on mean SaO2 during total sleep time as measured by pulse oximetry.
Total sleep time is the total of all rapid eye movement (REM) and non-REM sleep in a sleep episode.
|
Day 1 and Day 4
|
Percentage of Total Sleep Time That Arterial SaO2 is Less Than 90%, 85%, and 80%
Time Frame: Day 1 and Day 4
|
Evaluation of the percentage of the night in which SaO2 is less than 90%, less than 85% and less than 80% following multiple dose administration of suvorexant and placebo. Total sleep time is the total of all REM and non-REM sleep in a sleep episode. |
Day 1 and Day 4
|
Mean Arterial SaO2 for Different Sleep Stages
Time Frame: Day 1 and Day 4
|
Comparison of the mean SaO2 during different sleep stages (REM, Non-REM, and awake) following multiple dose administration of suvorexant and placebo.
Sleep stages were determined by polysomnography.
|
Day 1 and Day 4
|
Mean AHI
Time Frame: Day 1
|
Evaluation of the effect of multiple dose administration of suvorexant on AHI as measured by polysomnography. The AHI is an overall index of OSA severity. The AHI is calculated by dividing the number of apneas and hypopneas by the number of hours of sleep. AHI values are categorized as mild OSA = 5 to <15/hr and moderate OSA = 15 to <30/hr. |
