This is a randomized, controlled, open-label trial to investigate the antiviral activity, tolerability and safety of TMC114/r) versus lpv/rtv in treatment-naive HIV-1 infected patients. Six hundred sixty treatment-naïve HIV-1 infected patients will be randomized in a 1:1 ratio to either 800/100 mg of TMC114/r once daily, or a total daily dose of 800/200 mg of lpv/rtv. All patients will take TMC114/r or lpv/rtv in combination with an NRTI background of Truvada (a combination pill of tenofovir and emtricitabine, "TDF/FTC"). The trial will consist of a screening period of approximately 14 to 28 days and a 96-week treatment period, followed by a 4-week follow-up period. The anti HIV-1 therapy initiated at baseline cannot be changed until the end of the treatment period. After the end of the treatment period (maximum of 96 weeks), patients will be followed for an additional 4 weeks to follow-up on any adverse events or laboratory abnormalities until resolution. Patients who fail either virologically or due to intolerance from the TMC114/r or lpv/rtv therapy, as judged by the investigator, or who meet one of the withdrawal criteria will be withdrawn from the trial and may have the opportunity to participate in the rollover phase of the trial.
