Intense Acute Infection Study

Acute HIV Infection Clinical Trial

Official title: Randomized, Double-blinded, Controlled Trial Assessing the Effect of Intensive Treatment With HAART and the Integrase Inhibitor, Raltegravir, and the CCR5 -Receptor Antagonist, Maraviroc, on HIV-1 Pro-viral DNA and Reservoir Decay in HIV-1-infected Individuals Initiating Antiretroviral Therapy During the Acute Phase of Infection

Status Completed

Clinical Trial Summary

This trial will investigate the efficacy and safety of intensified antiretroviral treatment that includes raltegravir and maraviroc during the early stages of HIV infection. With the proven efficacy of these antiviral drugs in pre- and post-clinical trials, we would like to investigate the ability of the combination of raltegravir and maraviroc plus a standard HAART backbone to further decrease the viral load in acutely infected treated HIV infected individuals.

Clinical Trial Description

The trial is a prospective, randomized, double-blinded, placebo-controlled study with follow-up to 5 years. Thirty-two individuals presenting with newly diagnosed acute or early HIV-1 infection as described in the inclusion criteria will be enrolled, with sixteen randomized to each arm. Individuals will be randomized to one of two arms: the "Intensive" arm with standard HAART (Emtricitabine 200mg /tenofovir 300mg QD + Lopinavir 400mg /ritonavir 100mg BID) + Raltegravir + Maraviroc or the "placebo" arm with standard HAART+ Placebo for 48 weeks. Another group of individuals diagnosed with acute or early HIV-1 who elect to forego early treatment will be followed as non-randomized, untreated controls. At week 48, all patients will be informed of study results. If results are positive in the intensive treatment group, the placebo group will be offered to roll-over to the intense treatment arm and followed as an open-label cohort out to five years. Participants may stop treatment at any time and withdraw from the study. If they choose to do so, they will be followed according to the standards employed for all HIV-1 patients at the Maple Leaf clinic. At the five year point, the decision to terminate treatment will be made based on the existing state of the HIV-1 literature at the time. ;
