Measure Type	Secondary
Measure Title	Number of Participants With HIV-1 RNA <50 Copies/Milliliter (c/mL) and 400 c/mL at Week 96
Measure Description	HIV-1 RNA level (viral load) is a strong predictor of the rate of HIV disease progression. It was measured from plasma (participant blood samples) taken at all visits throughout the study. HIV, human immunodeficiency virus; RNA, ribonucleic acid. Viral load is a measure of the severity of the HIV infection.
Time Frame	Week 96
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.
ITT-E Population. Failures and missing values are derived according to the Time to Loss of Virologic Response (TLOVR) Food and Drug Administration (FDA) algorithm.

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 any 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 precede 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
