Atazanavir/Ritonavir, Once Daily + Raltegravir, Twice Daily, Switch Study in HIV-1-Infected Patients
SPARTAN
An Open-Label, Randomized Study Evaluating a Switch From a Regimen of Two Nucleoside Reverse Transcriptase Inhibitors Regimen Plus Any Third Agent to Either a Regimen of Atazanavir/Ritonavir Once Daily and Raltegravir Twice Daily or to a Regimen of Atazanavir/Ritonavir Once Daily and Tenofovir/Emtricitabine Once Daily in Virologically Suppressed HIV-1 Infected Subjects With Safety and/or Tolerability Issues on Their Present Treatment Regimen.

Brief Summary
The purpose of this study is to determine whether HIV-1-infected patients, who are virologically suppressed on a regimen of 2 nucleoside reverse transcriptase inhibitors plus any third agent but are experiencing safety and/or tolerability issues, will maintain virologic suppression after switching to a regimen of heat-stable ritonavir boosted atazanavir, 300/100 mg, once daily plus raltegravir, 400 mg, twice daily.

Outcome Measures
Primary Outcomes (1)
Percentage of Participants With HIV-1 RNA Level <40 c/mL at Week 24
HIV-1 RNA level was measured with the Abbott m2000rt® polymerase chain reaction assay. Response rates were assessed using an intent-to-treat algorithm, with numerator representing patients meeting the response criteria, and denominator representing all randomized patients. Randomized patients not meeting the criteria for treatment failure (eg, discontinuation of study therapy or virologic rebound at or before Week 24) were considered responders. Virologic rebound was defined as 2 consecutive on-treatment HIV-1 RNA levels ≥40 c/mL or the last on-treatment HIV-1 RNA level ≥40 c/mL followed by discontinuation. Patients who experienced treatment failure or had missing Week 24 HIV-1 RNA levels were considered failures. RNA=ribonucleic acid; HIV=human immunodeficiency virus.

Eligibility Criteria
You may qualify if:
- Current treatment regimen of 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus any third agent for at least 3 months immediately prior to screening
- Virologic suppression (HIV-1 RNA \<50 c/mL) for at least 3 months immediately prior to screening
- Virologic suppression (HIV-1 RNA \<40 c/mL) using the Abbott m2000rt® polymerase chain reaction assay during screening period
- Treatment-related safety and/or tolerability issues to a regimen consisting of 2 NRTIs plus any third agent
You may not qualify if:
- History of switch in highly active antiretroviral therapy due to virologic failure
- History of genotypic resistance to any component of the study regimen (atazanavir, raltegravir, tenofovir/emtricitabine)
- History of exposure to atazanavir/ritonavir or raltegravir prior to entering the study
- Experiencing safety and/or tolerability issues to tenofovir/emtricitabine or raltegravir
- Switch of any component of HIV antiretroviral medication regimen in the last 3 months immediately prior to or during the screening period
