Summary
This study is a prospective, open-label, randomized, three-arm, dose-escalation exploratory pilot clinical trial involving HIV-1 infected participants treated with suppressive combination antiretroviral combination therapy (cART). The study will test whether combined treatment with the histone deacetylase inhibitor panobinostat and the immunomodulatory cytokine Interferon-alpha2a can reduce the residual reservoir of HIV-1 infected cells that persist during treatment with currently available antiretroviral drugs.
