Monotherapy with darunavir/ritonavir or lopinavir/ritonavir versus standard antiretroviral therapy: a randomized clinical trial (2pm Study).

ABSTRACT

In a multicentre, open-label, clinical trial, 43 patients virologically suppressed while receiving a standard triple antiretroviral therapy were randomized (111) to switch to monotherapy with darunavir/ritonavir (DRV/r-MT arm), monotherapy with lopinavir/ritonavir (LPV/r-MT arm) or to continue on the ongoing regimen (cART arm). The proportion (95% CI) of patients with virological success (Snapshot analysis) at week 48 was 73% (48%-90%) in the DRV/r-MT arm, 69% (42%-88%) in the LPV/r-MT arm and 87% (61%-98%) in the cART arm. Virological failure was detected in only one patient receiving LPV/r-MT. The LPV/r-MT arm showed a modest worsening in lipid profile.
