Pilot Simplification Study to Lopinavir/Ritonavir 800/200 mg Monotherapy Regimen Once Daily
October 5, 2016 updated by: Daniel Podzamczer
Lopinavir/ritonavir monotherapy is currently a well known and widely used strategy, while Lopinavir/ritonavir 800/200 mg once a day in a triple-therapy was approved a few years ago.
The purpose of this study is to evaluate efficacy and safety of Lopinavir/ritonavir 800/200 mg monotherapy once a day.
