Biological: IMVAMUNE (MVA-BN)
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized

Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: A Multicenter, Open-label, Controlled Phase II Study to Evaluate Safety and Immunogenicity of MVA-BN® (IMVAMUNE) Smallpox Vaccine in 18-55 Year Old Naive and Previously Vaccinated HIV Infected Subjects With CD4 Counts >200 - 750/µl.

Primary Outcome Measures:
  • Occurrence, relationship and intensity of any serious and/or unexpected adverse reaction at any time during the study [ Time Frame: 35 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Occurrence of any Grade 3 or higher adverse reaction (missing, unknown, not evaluable, possibly, probably, or definitely related) to the study vaccine [ Time Frame: 28 days after each vaccination ] [ Designated as safety issue: Yes ]
  • Occurrence, intensity and duration of solicited local adverse events (erythema, swelling and pain) within one week after each vaccination [ Time Frame: 8 days ] [ Designated as safety issue: Yes ]
  • Occurrence, intensity and duration of systemic adverse events (pyrexia, headache, myalgia, nausea, fatigue and chills) within 1 week after each vaccination. Relationship to vaccination [ Time Frame: 8 days ] [ Designated as safety issue: Yes ]
  • Occurrence, intensity and duration of all unsolicited adverse events (i.e. serious + non-serious) within 4 weeks after each vaccination. Relationship to vaccination [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]
  • Plaque Reduction Neutralization Test (PRNT) specific seroconversion rates and geometric mean titers (GMTs) (at all blood sampling time points). [ Time Frame: up to 35 weeks ] [ Designated as safety issue: No ]
  • ELISA specific seroconversion rates and geometric mean titers (at all blood sampling time points). [ Time Frame: up to 35 weeks ] [ Designated as safety issue: No ]
  • Interferon (IFN) gamma producing T-cells in response to stimulation with MVA-BN (IMVAMUNE) detected by Enzyme-Linked Immunospot (ELISPOT) (only for the 165 subjects in the main study). [ Time Frame: up to 35 weeks ] [ Designated as safety issue: No ]
  • Change in CD4+ and CD8+ T-cell counts in HIV-infected subjects [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
