Background: Activating the expression of latent virus is an approach that might form part of an HIV cure. We assessed the ability of the histone deacetylase inhibitor panobinostat to disrupt HIV-1 latency and the safety of this strategy. Methods: In this phase 1/2 clinical trial, we included aviraemic adults with HIV treated at Aarhus University Hospital, Denmark. Participants received oral panobinostat (20 mg) three times per week every other week for 8 weeks while maintaining combination antiretroviral therapy. The primary outcome was change from baseline of cell-associated unspliced HIV RNA. Secondary endpoints were safety, plasma HIV RNA, total and integrated HIV DNA, infectious units per million CD4 T cells, and time to viral rebound during an optional analytical treatment interruption of antiretroviral therapy. This trial is registered with, number NCT01680094. Findings: We enrolled 15 patients. The level of cell-associated unspliced HIV RNA increased signifi cantly at all timepoints when patients were taking panobinostat (p
