Measure Type Primary
Measure Title Area Under the Plasma Concentration Versus Time Curve (AUC) From Time 0 to 24 Hours Post-dose (AUC(0-24))
Measure Description AUC(0-24) is measure of area under the curve over the dosing interval (tau), where tau is the length of the dosing interval (24 hours), calculated using the linear trapezoidal rule. Pharmacokinetic parameters were derived using noncompartmental methods from the plasma concentrations of dexlansoprazole.
Time Frame Day 7 after 7 days of dosing with dexlansoprazole delayed release capsules.  
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.
Pharmacokinetic set included all participants with at least one estimable PK parameter for dexlansoprazole on Day 7.

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
