A Study of Ritonavir-Boosted Invirase (Saquinavir) in Treatment-Naïve HIV-1 Infected Patients
To Determine the Effect of the Modified SQV/r (Saquinavir-boosted by Ritonavir) Regimen (500/100 mg for the 1st Week Followed by 1000/100 mg for the 2nd Week) on the QTc Interval, Pharmacokinetics, and Antiviral Activity in Treatment-naive HIV-1 Infected Patients
