Reasons for exclusion from the ATP immunogenicity analysis included essential data on CD4+ T-cell responses missing, concomitant infection and lack of compliance with the vaccination schedule. Reactogenicity during the 7-day post-vaccination period is shown in Table 2. Pain was the only solicited local AE reported by more than 1 subject in any group after either dose and was more common in the F4/AS01 groups than in the placebo

groups. The most common solicited general AEs were fatigue and headache in ART-experienced subjects and fatigue, headache, myalgia and sweating in ART-naïve subjects. No solicited grade 3/4 AEs were reported by more than 1 subject in any group. All solicited local AEs http://www.selleckchem.com/Wnt.html and most solicited general AEs were considered related to vaccination by the investigator. The percentage of subjects reporting unsolicited AEs during the 30-day post-vaccination period is shown in Table S1. After the 30-day post-vaccination period, 5 and 4 subjects in the ART-experienced vaccine and placebo groups and 9 and 10 subjects in the ART-naïve vaccine and

placebo experienced at least one unsolicited AE requiring medical attention. All unsolicited AEs were heterogeneous in nature and no apparent trends were noted. No grade 3/4 laboratory Selleckchem Cabozantinib parameters were reported in the vaccine group in either cohort, with the exception of grade 3 bilirubin in one ART-experienced subject which was related to atazanavir use. Table S1.   Percentage of subjects reporting unsolicited adverse events during the 30-day post-vaccination period (TVC). No SAEs were reported in the ART-experienced group. SAEs were reported by 3 ART-naïve vaccine recipients (injury of the rectum, hepatitis B and cholelithiasis) and 3 ART-naïve placebo recipients (ophthalmic

herpes zoster with bacterial superinfection, personality disorder with pyelonephritis and pyomyositis). All SAEs were considered unrelated to vaccination and resolved without sequelae. HIV-1-related AEs were observed in 6 subjects in each of the ART-experienced Dipeptidyl peptidase groups and 8 and 11 subjects in the ART-naïve vaccine and placebo groups, respectively (Table 3). Pre-existing F4-specific CD40L+CD4+ T-cells expressing at least IL-2 were detected at a low frequency in both groups in ART-experienced and ART-naïve subjects prior to vaccination. Exploratory analyses showed the frequency of F4-specific CD40L+CD4+ T-cells expressing at least IL-2 to be significantly higher (p < 0.05) in the vaccine group than in the placebo group two weeks post-dose 2 in both cohorts ( Fig. 1). In ART-experienced subjects, this difference between the vaccine and the placebo groups remained significant up to month 4 (p < 0.05), and F4-specific CD4+ T-cell responses were still detected in vaccine recipients at month 12.
