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)

Time Frame Adverse event data were collected from study entry until the end of study (28 days for Cohorts 1-3 and up to 48 weeks for Cohort 4).
Adverse Event Reporting Description The protocol required reporting of all diagnoses, all signs/symptoms/laboratory values Grade ≥ 2, and all signs/symptoms/laboratory values that led to treatment change and/or Grade ≥ 3 and/or met EAE or ICH reporting requirements. For grading, sites referred to the DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), Version 1.0, December 2004 (Clarification, August 2009), http://rsc.tech-res.com/clinical-research-sites/safety-reporting.
