The purpose of this study is to look at the safety and efficacy of a combination of 3 new antiretroviral drugs: darunavir, etravirine and MK-0518 (raltegravir) in patients who have multi-resistant viruses and limited treatment options. An optimized background regimen that may include nucleoside reverse transcriptase inhibitors (NRTIs) and enfuvirtide can be added, if possible, to this combination. Patients will undergo treatment for 48 weeks and virological efficacy will be evaluated at week 24.

The researchers are involved in a phase II, randomized, two-arm study, comparing the efficacy, safety, and tolerability of open-label ritonavir (RTV)-enhanced darunavir with Truvada to a 5-drug multi-class regimen including truvada, darunavir/ritonavir/maraviroc/and raltegravir on acutely HIV-1-infected, antiretroviral (ARV) drug-naïve men and women. Subjects will participate for at least 60 weeks and up to 96 weeks if in the opinion of the investigator and patient that continued therapy is in the patient's best interest. Hypotheses: - Multi-class antiretroviral therapy (ART) is superior to RTV-enhanced ATV in combination with Emtricitabine/Tenofovir DF (FTC/TDF) with respect to suppression of viral replication. - Multi-class ART is superior to RTV-enhanced ATV in combination with FTC/TDF with respect to immune reconstitution in peripheral blood and in the gastrointestinal mucosa. - Multi-class ART is equivalent to RTV-enhanced ATV in combination with FTC/TDF with respect to tolerability.
