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.
Major resistance-associated mutations include: NRTI: K65R or inserts Q151M, M184V/I, PI: I50L/V, I84V, N88S. --- K65R --- --- Q151M --- --- M184V --- --- I50L ---
