A Nucleoside- and Ritonavir-Sparing Regimen Containing Atazanavir Plus Raltegravir in Antiretroviral Treatment-Naïve HIV-Infected Patients: SPARTAN Study Results

ATV+RAL, an experimental NRTI- and RTV-sparing regimen, achieved virologic suppression rates comparable to current standards of care for treatment-naïve patients. The overall profile did not appear optimal for further clinical development given its development of resistance to RAL and higher rates of hyperbilirubinemia with twice-daily ATV compared with ATV/RTV.
