The table below shows pharmacokinetic (PK) results of atazanavir (ATZ) when administered as ATV/rtv 300/100 mg pretreatment (Reference) and at Week 2 after treatment (Test). Results are expressed as the predose plasma concentration (C0h), minimum plasma concentration (Cmin), and maximum plasma concentration (Cmax).
The table below shows pharmacokinetic (PK) results of atazanavir (ATZ) when administered as ATV/rtv 300/100 mg pretreatment (Reference) and at Week 2 after treatment (Test). Results are expressed as the area under the plasma concentration-time curve from time of intake to 24 hours after dosing (AUC24hr).

The table below shows the pharmacokinetic (PK) results of low-dose ritonavir (rtv) when administered as atazanavir (ATV)/rtv 300/100 mg pretreatment (Reference) and at Week 2 after treatment (Test). Results are expressed as the predose plasma concentration (C0h), minimum plasma concentration (Cmin), and maximum plasma concentration (Cmax).
The table below shows the pharmacokinetic (PK) results of low-dose ritonavir (rtv) when administered as atazanavir (ATV)/rtv 300/100 mg pretreatment (Reference) and at Week 2 after treatment (Test).

The table below shows pharmacokinetic (PK) results of low-dose ritonavir (rtv) when administered as atazanavir (ATV)/ritonavir (rtv) 300/100 mg pretreatment (Reference) and when administered as ATV/rtv 400/100 mg at Week 2 after treatment (Test). Results are expressed as the predose plasma concentration (C0h), minimum plasma concentration (Cmin), maximum plasma concentration (Cmax), and area under the plasma concentration-time curve from time of intake to 24 hours after dosing (AUC24hr).
The table below shows pharmacokinetic (PK) results of low-dose ritonavir (rtv) when administered as atazanavir (ATV)/ritonavir (rtv) 300/100 mg pretreatment (Reference) and when administered as ATV/rtv 400/100 mg at Week 2 after treatment (Test). Results are expressed as the area under the plasma concentration-time curve from time of intake to 24 hours after dosing (AUC24hr).
The table below shows pharmacokinetic (PK) results of ETR in the current study expressed as the predose plasma concentration (C0h), minimum plasma concentration (Cmin) and maximum plasma concentration (Cmax).
The table below shows pharmacokinetic (PK) results of ETR in the current study expressed as the area under the plasma concentration-time curve from time of intake to 12 hours after dosing (AUC12hr).
The table below shows the percentage of participants wih undetectable plasma viral load (VL) values (\<50 copies/mL) at Week 48 using the Non-Completing = Failure (NC=F) imputation method (ie, participants who discontinued early were counted as nonresponders by having their VL values after discontinuation imputed with their baseline value, thus resulting in a 0 change).
