Switching to darunavir/ritonavir 800/100 mg once-daily containing regimen maintains virological control in fully suppressed pre-treated patients infected with HIV-1

The objective of this study was to evaluate the switch to once‐daily darunavir/ritonavir 800/100 mg in treatment‐experienced patients with suppressed HIV‐1 replication on a twice‐daily ritonavir‐boosted protease‐inhibitor (bid PI/r) containing regimen, that is in a setting where genotypic resistance test cannot be performed. In this open label, non‐comparative, multicenter study, patients on a bid PI/r‐containing triple combination, with suppressed viral replication, were switched to once‐daily darunavir/r 800/100 mg containing triple combination. The primary endpoint was the proportion of patients with plasma HIV‐RNA
