Induction-Maintenance With Atazanavir in HIV Naïve Patients (The INDUMA Study) (INDUMA)

7 januari 2010 bijgewerkt door: Bristol-Myers Squibb

A Phase IV, Open-Label, Randomized, Multicenter Trial Assessing the Efficacy of a Treatment Maintenance Phase With Unboosted vs. Boosted Reyataz After an Induction Phase With Reyataz and Ritonavir in Treatment Naive HIV Patients (the INDUMA Study)

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.
