39.Secondary Outcome
Title Change From Baseline in PTEF-b Phosphorylation (pS175+%) in CD4+ T-cells in Cohort 4
Hide Description Baseline is defined as the average of the pre-entry and entry values. Change was calculated as the value at 24 hours after each administration of Romidepsin or placebo (at entry, and days 14, 28 and 42) and 72 hours after the second administration (at day 14) minus the value at baseline.
Time Frame Pre-entry, entry, 24 hours after each administration of Romidepsin or placebo (at entry, and days 14, 28 and 42) and 72 hours after the second administration (at day 14)
