Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Participants were enrolled by HIV care providers between December 2005 and June 2008. When the main study ended in February 2009, patients who consented to a study extension were followed another 2 years, during which study drug was not given.

Reporting Groups
  Description
No IL-2 Participants will receive no aldesleukin or HAART during the main study or extension
IL-2 Without ART During the main study, participants will receive aldesleukin under the skin twice daily for 5 consecutive days every 8 weeks for 3 cycles, then as needed to maintain CD4 counts at or above a goal level. Patients did not receive aldesleukin during the extension phase.
IL-2 With Pericycle HAART During the main study, participants will receive aldesleukin under the skin twice daily for 5 consecutive days every 8 weeks for 3 cycles, then as needed to maintain CD4 counts at or above a goal level; in addition, this group will also take HAART for 3 days prior to the start of each aldesleukin cycle, throughout the 5-day aldesleukin cycle, and for 2 days after the end of each aldesleukin cycle (for a maximum of 10 days with each aldesleukin cycle). Patients did not receive aldesleukin during the extension phase.

Measure Type Post-Hoc
Measure Title Undetectable HIV-RNA
Measure Description Patients with undetectable HIV-RNA levels measured at 24 months after the close of the main study, at the end of the extension phase.

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.
All patients for whom an HIV-RNA measurement was available during the extension phase. Because the focus of the extension was on the safety of patients exposed to IL-2, the outcomes were summarized for the two groups exposed to IL-2 vs. the group that did not take IL-2.

Reporting Groups
  Description
IL-2 Consenting patients who were assigned IL-2 during the main phase of the study, including patients who took IL-2 alone as well as patients who took IL-2 with ART.
Control Consenting patients who were in the control group during the main phase of the trial.

  Serious Adverse Events


  Other Adverse Events


  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
All randomized patients were followed through 28 Feb 2009. A subset of 222 consenting patients were followed 2 additional years, through 28 Feb 2011.
