Measure Type Secondary
Measure Title Mean Change From Baseline In Subject-Reported Counts of Number of Naps Per Week at Various Study Time Points
Measure Description Change from baseline in the number of naps per week for subjects who napped during the baseline period. The change is calculated as value during double-blind phase(weeks 3,6,9,12), or the single-blind follow-up(week 14), or the non-drug treatment follow-up(week 16) minus the baseline value.
Time Frame Baseline (week 0), Weeks 3,6,9,12,14,16  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Intention to Treat (ITT) population; Only subjects in the ITT population with at least one post-dose assessment and who napped at baseline are included. Last Observation Carried Forward.

Certain Agreements:  
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The data gathered was subjective (except for actigraphy endpoints) and relied either on self reporting or patient assessments derived from standardized questionnaires.
