Reporting Groups
  Description
ATV/Rtv 300/100 mg (Treatment A) Treatment-experienced human immunodeficiency virus – type 1 (HIV-1) infected participants took by mouth atazanavir (ATV)/low-dose ritonavir (rtv) 300/100 mg once daily + 2 nucleoside reverse transcriptase inhibitors (NRTIs) for pre-treatment for 2 weeks followed by ATV/rtv 300/100 mg once daily + etravirine (ETR) 200 mg twice daily + 1 NRTI for 48 weeks.
ATV/Rtv 400/100 mg (Treatment B) Treatment-experienced human immunodeficiency virus – type 1 (HIV-1) infected participants took by mouth atazanavir (ATV)/low-dose ritonavir (rtv) 300/100 mg once daily + 2 nucleoside reverse transcriptase inhibitors (NRTIs) pretreatment for 2 weeks followed by ATV/rtv 400/100 mg once daily + etravirine (ETR) 200 mg twice daily + 1 NRTI for 48 weeks.
