Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 219 participants were enrolled and 18 were never randomized (1 poor/noncompliance; 10 no longer met study criteria; 5 withdrew consent). 201 participants were randomized; however, 1 participant was never treated and is not included in the participant flow.

Reporting Groups

	Description
ATV/RTV Switch Arm	Participants switching their current treatment with a ritonavir (RTV)-boosted protease inhibitor (PI)-containing highly active antiretroviral therapy (HAART) regimen to atazanavir (ATV)/RTV (ATV: 2 x 150 mg capsules once daily (QD) / RTV: 1 x 100 mg capsule QD) while continuing their background nucleoside reverse transcriptase inhibitors (NRTIs).
PI/RTV Control Arm	Participants continued on their current treatment with an RTV-boosted, PI-containing HAART regimen while continuing their background NRTIs.

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: Bristol-Myers Squibb Co. agreements with investigators vary; constant is our right to embargo communications regarding trial results prior to public release for a period ≤60 days from submittal for review. We will not prohibit investigators from publishing, but will prohibit the disclosure of previously undisclosed confidential information other than study results, and request postponement of single-center publications until after disclosure of the clinical trial's primary publication.
