This study is a Phase II single arm, open-label, multicenter, study of 50 human immunodeficiency virus-1 (HIV) infected adult patients, all of whom will receive etravirine (ETR) 400mg and DRV/r 800/100mg each given orally once daily. This trial is designed to evaluate the efficacy of the aforementioned ARV regimen, as measured by the percentage of patients with HIV RNA <50 copies/mL at 48 weeks, in early treatment-experienced HIV-infected patients. In addition to general safety parameter measurements, this trial will also assess changes in metabolic, inflammatory, immune restoration, and bone markers. Screening will occur over a 6-week period. The primary endpoint will be assessed at Week 48, and the treatment period is 48 weeks. The end of study endpoint will be met by either completing the Week 48 visit, or by early termination from the study for any reason.

Inclusion Criteria: - Male or female patients, aged 18 years or above - Patients with documented HIV-1 infection - On current HAART regimen for at least 12 weeks continuous duration at screening, and with an HIV-1 plasma viral load above 500 HIV-1 RNA copies/mL by site's currently utilized viral load assay (Note: For the purposes of this study, HAART is defined as treatment with a combination of 3 or more HIV antiretroviral medications from at least 2 different classes of medications (NRTIs, NNRTIs, PIs, integrase inhibitors, CCR5 antagonists, fusion inhibitors)) - No more than 2 previous virologic failures while on PI-containing HAART regimens where virologic failure is generally defined as either a lack of suppression of the subjects' viral load to lower limit of quantification (per standard assay historically used in care) after 24 weeks of treatment or, rebound of a previously suppressed viral load (undetectable per investigator's standard of care) to detectable limits and without demonstrated re-suppression on the same regimen - Demonstrated phenotypic sensitivity to both etravirine and darunavir based on resistance testing at Screening (FC= 2.9 for etravirine and FC = 10.0 for darunavir using the PhenoSense GT) - The absence of all of the following Resistance Associated Mutations (RAMS) at baseline: For Darunavir: V11I, V32I, L33F, I47V, I50V, I54L/M, T74P, L76V, I84V, L89V - For Etravirine: L100I, E138A, I167V, V179D, V179F, Y181I, Y181V, G190S - 7.
