Last Updated: 2013-09-30

Results Overview

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).

Participant Flow

Etravirine coadministered with 2 doses of atazanavir/low-dose ritonavir each combined with 1 nucleoside reverse transcriptase inhibitor was evaluated in human immunodeficiency virus - type 1 infected participants. The study was conducted between 25 June 2009 and 10 April 2012 and participants were recruited by 17 investigators in 4 countries.

Fifty (50) participants were enrolled in the study and received treatment with study drug during a 2-week Pre-treatment Period (Week -2 to Day -1) and a 48-week Treatment Period (Day 1 to Week 48). Efficacy data are reported for the 48-week Treatment Period.

PRIMARY outcome

Timeframe: Day -1 (Pretreatment); Week 2 (Test)

Population: The population analyzed included all randomized participants with at least 1 etravirine (ETR) intake regardless of their compliance with the protocol (ie, the efficacy ITT population) for which data was available for the PK parameter reported.

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 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).
