BACKGROUND Cobicistat is an alternative pharmacoenhancer to ritonavir. In healthy volunteers, darunavir exposure was comparable when darunavir 800 mg once daily was co-administered with cobicistat 150 mg once daily (as single agents or a fixed-dose combination) vs. with ritonavir 100 mg once daily. METHODS This 48-week, Phase IIIb, single-arm, US(More)
An existing population pharmacokinetic model of darunavir in adults was updated using pediatric data from two studies evaluating weight-based, once-daily dosing of darunavir/ritonavir (ARIEL, NCT00919854 and DIONE, NCT00915655). The model was then used to provide once-daily dosing recommendations for darunavir/ritonavir in pediatric patients aged ≥3 to <12(More)
INTRODUCTION In DUET, etravirine (ETR) 200 mg bid had durable efficacy and a favourable safety profile versus placebo, both arms with an optimised background regimen (BR) including darunavir/ritonavir (DRV/r). TMC125IFD3002 (VIOLIN; NCT01422330) investigated ETR plus ARVs other than DRV/r. MATERIALS AND METHODS This was a 48 week, Phase IV, open-label,(More)
INTRODUCTION COBI, a PK enhancer with no ARV activity is a more selective cytochrome P450 (CYP)3A inhibitor than ritonavir (RTV), does not induce CYP isozymes, and thus has less potential for drug-drug interactions. COBI boosts DRV PK as effectively as RTV in healthy volunteers. MATERIALS AND METHODS This 48-week, phase IIIb, open-label, single-arm, US(More)
