Measure Type	Secondary
Measure Title	Adjusted Mean Change From Baseline of Circadian Variation in PEF(%) During the 20-Week Extension Treatment Period
Measure Description	Mean change from baseline = value at assessment period (mean of the values obtained at assessment period [Weeks 11-30]) minus baseline value. Baseline: Mean of the daily values over the last 7 days prior to the day of starting the Extension period (Weeks 11-30).
Time Frame	Extension Period weeks 11-30
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.
FAS (Full Analysis Set) during the Extension period: all subjects switched to Extension period and received GW815SF HFA MDI.

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:

	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.
	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.
	Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed. Restriction Description: GSK agreements may vary with individual investigators, but will not prohibit an investigator from publishing. GSK supports the publication of results from all centers of a multi-center trial but requests that reports based on single-site data not preceed the primary publication of the entire clinical trial.

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
