Pilot Peg-Interferon-a2b in Decreasing Viral DNA in HIV

Completed · Phase 2

Conditions studied: HIV-1 Infection

In brief

We propose to test our primary hypothesis that treatment with Peg-IFN-α-2b will result in a decrease in integrated HIV DNA in peripheral blood and tissue in chronically HIV-infected immune-reconstituted individuals (see section 3.1) in a prospective, interventional, 1-arm, open label clinical trial. To this end, we propose to enroll 25 HIV-1-infected subjects (please refer to power calculations in section 10.1 below) currently stably suppressed (\> 1y with VL \< 50 copies/ml) on ART and with CD4 count \> 450 cells/µl. We hypothesize that 20 weeks of treatment with Peg-IFN-alpha-2b, in the presence of HIV reactivation (i.e.: ART interruption), will result in activation of intrinsic and/or immune-mediated anti-HIV mechanisms resulting in a decrease in the levels of viral reservoir in chronically HIV-infected, immune-reconstituted individuals.
