A Phase 1/2 Randomized, Placebo-Controlled Trial of Romidespin in Persons With HIV-1 on Suppressive Antiretroviral Therapy.

ABSTRACT:

Background

Romidepsin (RMD) is a histone deacetylase inhibitor reported to reverse HIV-1 latency. We sought to identify doses of RMD that were safe and induced HIV-1 expression.

Methods

Enrollees had HIV-1 RNA <40 copies/mL on antiretroviral therapy. Measurements included RMD levels, plasma viremia by single-copy HIV-1 RNA assay, HIV-1 DNA, cell-associated unspliced HIV-1 RNA (CA-RNA), acetylation of histone H3-lysine-9 (H3K9ac+), and phosphorylation of transcription factor P-TEFb. Wilcoxon tests were used for comparison.

Results

In the single-dose cohorts 1-3, 43 participants enrolled (36 participants 0.5, 2, 5 mg/m 2 RMD; 7 placebo) and 16 enrolled in the multidose cohort 4 (13 participants 5 mg/m 2 RMD; 3 placebo). One grade 3 event (neutropenia) was possibly treat
