Atazanavir/Ritonavir, Once Daily + Raltegravir, Twice Daily, Switch Study in HIV-1-Infected Patients (SPARTAN)

2 février 2015 mis à jour par: Bristol-Myers Squibb

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.

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.

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Percentage of Participants With HIV-1 RNA Level <40 c/mL at Week 24
Délai: From Day 1 to 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.
From Day 1 to Week 24

Délai
Percentage of Participants With HIV-1 RNA Level <40 c/mL at Week 48
Délai: From Day 1 to Week 48
Percentages of patients with HIV-1 RNA levels <40 c/mL were summarized at each scheduled visit. Longitudinal plots were created to display proportion versus visit week through Weeks 24 and 48 with error bars representing 95% confidence intervals.
From Day 1 to Week 48
Number of Participants With Virologic Rebound at Weeks 24 and 48
Délai: Day 1 to Weeks 28 and 48
Viral genotypic and phenotypic resistance profiles were assessed for virologic rebound (HIV-1 RNA level ≥40 c/mL). Only patients with HIV-1 RNA levels ≥500 c/mL met the criteria for resistance testing. Genotypic substitutions at baseline were summarized for virologic rebound. The genotypic resistance profile presented patients with genotypable isolates, those with protease inhibitor substitutions from genotypable isolates, those with integrase substitutions from genotypable isolates, and those with selected reverse transcriptase substitutions from genotypable isolates using the most current version of the International AIDS Society-USA list and Stanford HIV Drug Resistance Database. Newly emergent genotypic substitutions were summarized analogously for virologic rebound without baseline phenotypic resistance to atazanavir, ritonavir, or raltegravir, using all on-treatment isolates.
