- Primary Outcome Measures
Name Time Method Serious Adverse Events within 32 weeks Incidence, relationship and intensity of any Serious Adverse Event (SAE)
- Secondary Outcome Measures
Name Time Method Unsolicited Adverse Events: Incidence within 29 days after any vaccination Incidence of any unsolicited adverse events
Unsolicited Adverse Events: Intensity within 29 days after any vaccination Occurrence of unsolicited adverse events by Intensity
Unsolicited Adverse Events: Relationship to Vaccination within 29 days after any vaccination Occurrence of unsolicited adverse events by relationship to study vaccine
CD4+ T-cell Counts within 32 weeks Median CD4+ T-cell counts over time
CD8+ T-cell Counts within 32 weeks Median CD8+ T-cell counts over time
Viral Load within 32 weeks Viral load (HIV-1 RNA levels) over time
Related Grade >=3 Adverse Events within 29 days after any vaccination Incidence of any Grade 3 or higher adverse drug reaction (missing, unknown, not evaluable, possibly, probably, or definitely related) to the study vaccine
Solicited Local Adverse Events within 8 days after any vaccination Incidence and intensity of solicited local AEs (pain, erythema, swelling). Percentages based on subjects with at least one completed diary card.
Solicited General Adverse Events within 8 days after any vaccination Incidence of solicited general AEs (increased body temperature, headache, myalgia, chills, nausea, and fatigue): Intensity and relationship to vaccination. Percentages based on subjects with at least one completed diary card.
PRNT Seroconversion Rate within 32 weeks Seroconversion rate based on vaccinia-specific Plaque Reduction Neutralization Test (PRNT). Seroconversion is defined as the appearance of antibody titers ≥ detection limit (6) for initially seronegative subjects, or a doubling or more of the antibody titer compared to Baseline titer for initially seropositive subjects. Percentages based on number of subjects with data available.
PRNT GMT within 32 weeks Geometric Mean Titers (GMT) based on vaccinia-specific Plaque Reduction Neutralization Test (PRNT). Titers below the detection limit are included with a value of '1'.
ELISA Seroconversion Rate within 32 weeks Seroconversion rate based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). Seroconversion is defined as the appearance of antibody titers ≥ detection limit (50) for initially seronegative subjects, or a doubling or more of the antibody titer compared to Baseline titer for initially seropositive subjects. Percentages based on number of subjects with data available.
ELISA GMT within 32 weeks Geometric Mean Titers (GMT) based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). Titers below the detection limit are included with a value of '1'.
ELISPOT IFN-γ: Response Rate within 32 weeks Response rate based on number of subjects with response in an interferon gamma (IFN-γ) ELISPOT assay. Response is defined as the appearance of a signal in subjects that had no signal at Baseline or a relative increase by a factor of ≥1.7 compared to Baseline in subjects that had a signal at Baseline. Percentages based on number of subjects with data available.
ELISPOT IFN-γ: SFU within 32 weeks Median number of interferon gamma (IFN-γ) secreting peripheral blood mononuclear cells (PBMC) in response to stimulation with MVA-BN detected by ELISPOT assay.
