NCT00207142

Brief Summary

The purpose of this study is to compare the proportion of subjects with HIV-1 RNA viral load \< 50 c/mL through Week 48 of the Maintenance Phase among HIV-infected subjects with an initial undetectable viral load following an Induction Phase with an ATV/RTV containing HAART regimen, when switched to ATV versus remaining on ATV/RTV, whilst continuing their previous NRTI backbone.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With HIV-1 RNA <50 Copies/mL (c/mL) Through Week 48 of the Maintenance Phase

    Participants were considered successes unless they experienced treatment failure, or had missing Week 48 HIV-1 RNA. Treatment failure: virologic rebound (ie, 2 consecutive on-treatment HIV-1 RNA ≥ 50 c/mL, or last HIV-1 RNA ≥ 50 c/mL followed by discontinuation), or discontinuation before Week 48. Denominator included all randomized participants.

    From the end of Induction Phase (Week 26 to Week 30 of Induction Phase treatment) through Week 48 of Maintenance Phase

Secondary Outcomes (16)

  • Percentage of Participants With HIV-1 RNA <400 c/mL Through Week 48 of the Maintenance Phase

    From the end of Induction Phase (Week 26 to Week 30 of Induction Phase treatment) through Week 48 of Maintenance Phase

  • Kaplan-Meier Cumulative Proportion for Treatment Failure (HIV-1 RNA ≥50 c/mL) at Different Time Points Through Week 48 of the Maintenance Phase

    Weeks 6-8, Weeks 14-16, Weeks 22-24, Weeks 30-32, Weeks 38-40, Weeks 46-48

  • Kaplan-Meier Cumulative Proportion for Treatment Failure (HIV-1 RNA ≥400 c/mL) at Different Time Points Through Week 48 of the Maintenance Phase

    Weeks 6-8, Weeks 14-16, Weeks 22-24, Weeks 30-32, Weeks 38-40, Weeks 46-48

  • Change From End of Induction Phase in CD4 Cell Count at Week 48 of Maintenance Phase

    End of Induction Phase (Week 26 to Week 30 of Induction Phase treatment), Week 48 of Maintenance Phase

  • Change From Baseline in CD4 Cell Count at Week 24 of Induction Phase

    Baseline, Week 24 of Induction Phase

  • +11 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Treatment naive HIV-1 infected subjects ( \< 10 days of treatment with any ARV).
  • Subjects who have an HIV-1 RNA level ≥ 5000 c/mL at screening.
  • Subjects who have a CD4 count ≥ 50 cells/mm3.
  • Men and women, ages 18 years of age or older (or minimum age as determined by local regulatory or as legal requirements dictate).
  • Both females of child-bearing potential and males must utilize effective barrier contraception. Other contraception in addition to barrier methods is permitted; refer to the Investigator Brochure for details regarding potential interactions with ATV and some oral contraceptives

You may not qualify if:

  • WOCBP who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for up to 8 weeks after the study.
  • WOCBP using a prohibited contraceptive method. Caution is warranted with coadministration of oral contraceptives (ethinyl estradiol and norethindrone) - see Investigator Brochure for details
  • Women who are pregnant or breastfeeding
  • Women with a positive pregnancy test on enrollment or prior to study drug administration.
  • Presence of a newly diagnosed HIV-related opportunistic infection or any medical condition requiring acute therapy at the time of enrollment
  • Primary HIV infection
  • Medical History and Concurrent Diseases
  • Active alcohol or substance use sufficient, in the investigator's opinion, to prevent adequate compliance with study therapy or to increase the risk of developing pancreatitis or chemical hepatitis Physical and Laboratory Test Findings
  • Screening laboratory values measured as follows:
  • Grade IV glucose,
  • Grade IV electrolytes,
  • Grade IV transaminases,
  • Grade IV hematology.
  • Hypersensitivity to any component of the formulation of study drug
  • Prior history of taking any ARV for more than 10 days
  • +2 more criteria
