The purpose of this randomized, open-label study is to evaluate virological efficacy and safety of two double protease inhibitor regimens: atazanavir/fosamprenavir/ritonavir 300 mg once daily/ 700/100 mg twice daily, versus atazanavir/saquinavir/ritonavir 300/1500/100 mg once daily in protease inhibitor naive HIV-1 patients.~Patients with CD4 cell counts over or equal to 200/mm3, HIV viral load between 10,000 and 750,000 copies per milliliter, and wild-type genotype at baseline will be eligible. This multicenter study will enroll 60 patients (n=30 in each group). The planned duration of the study is 48 weeks from the enrolment of the last subject.~The primary efficacy endpoint will be virologic success defined as HIV RNA levels below 50 copies/ml after 16 weeks of initial treatment. The durability of this response will be evaluated and patients will be followed for 48 weeks.~The primary safety endpoint will be treatment interruptions because of adverse effects.
