Brief Summary:
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.
