Measure Type Other Pre-specified
Measure Title Serious Adverse Events in Open Label run-in Period
Measure Description Serious adverse events occuring during the 2 week run-in period (Period II) when all participants were dosed with celecoxib 200 mg daily
Time Frame 2 weeks prior to double blind dosing  
Safety Issue Yes  

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.
1197 participants entered the open-label run-in (period II) to allow observation of successful treatment of an osteoarthritis flare. 875 participants were randomized to double blind treatment (period III). 322 participants were not randomized.

Reporting Groups

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
