  • Adverse Events collected per subject [ Time Frame: 6 to 24 months post vaccination ] [ Designated as safety issue: Yes ]
    AEs are recorded for 28 days post vaccination SAEs are recorded for the entire study period to assess the safety profile
  • Number of cases of TB are collected in the subjects entered in the study [ Time Frame: 24 months post vaccination ] [ Designated as safety issue: No ]
    To evaluate the efficacy of AERAS-402 in the prevention of TB in infants based on TB case definition endpoint #1 as described in the protocol.

  • Percentage of cells expressing various cytokines will be measured in all subjects [ Time Frame: 24 months post vaccination ] [ Designated as safety issue: No ]
    To evaluate the immunogenicity of AERAS-402 compared to controls, flow cytometric intracellular cytokine staining (ICS) of CD4 and CD8 T cells producing one, two or three cytokines (IFN-γ, TNF-α, and/or IL-2) simultaneously after stimulation with a peptide pool of mycobacterial peptides.
  • Number of subjects that have positive QuantiFERON tests after vaccination [ Time Frame: 24 months post vaccination ] [ Designated as safety issue: No ]
    To evaluate the proportion of on-study QuantiFERON conversions in infants that received AERAS-402 compared to controls.
  • Number of subjects with probable TB [ Time Frame: 24 months post vaccination ] [ Designated as safety issue: No ]
    To evaluate the efficacy of AERAS-402 in the prevention of TB in infants based on TB case definition endpoints #2 and #3 as specified in the protocol.

Study of AERAS-402 in Healthy Infants
A Phase II, Double-blind, Randomized, Placebo-controlled, Multicenter Study to Evaluate the Safety and Immunogenicity of AERAS-402 in BCG-vaccinated, HIV-uninfected Infants Without Evidence of Tuberculosis

AERAS-402 will be given to infants of at least 16 weeks of age who have already been vaccinated with BCG to determine if AERAS-402 will increase protection of infants to tuberculosis.

The only currently available tuberculosis vaccine, bacillus Calmette-Guérin (BCG), is estimated to reduce the risk of tuberculosis (TB) in children by up to 70-80%, but protection is incomplete. Efforts to increase TB protection in children include new vaccines for primary immunizations as well as combinations of vaccines given as primary and boosting vaccinations. AERAS 402 presents Mycobacterium tuberculosis (Mtb) antigens in the setting of a new, live, replication-deficient adenovirus vaccine that may increase T cell-mediated immunity and thus protection from tuberculosis. AERAS-402 appears safe and immunogenic in adults. Since BCG-vaccinated infants are the population for which AERAS-402 might be indicated, AERAS-402 will be administered to infants of at least 16 weeks of age who have already been vaccinated with BCG. This is the first Phase II study of AERAS-402 in infants.

  • Experimental: Group One - Dose Finding - Low Dose
    Subjects enrolled in Study Group 1 will be randomized in a ratio of 3:1 to receive two doses of AERAS-402 at the lowest dose level or placebo, once on Study Day 0 and again on Study Day 28.
    Intervention: Biological: AERAS-402
  • Experimental: Group 2 - Dose Finding - Middle dose -
    Subjects enrolled in Study Group 2 will be randomized in a ratio of 3:1 to receive two doses of AERAS-402 at the middle dose level or placebo, once on Study Day 0 and again on Study Day 28.
    Intervention: Biological: AERAS-402
  • Experimental: Group 3 - Dose Finding - High Dose
    Subjects enrolled in Study Group 3 will be randomized in a ratio of 3:1 to receive two doses of AERAS-402 at the highest dose level or placebo, once on Study Day 0 and again on Study Day 28.
    Intervention: Biological: AERAS-402
  • Experimental: Group 5 - Safety Cohort
    Subjects will receive three doses of AERAS-402 at the selected dose level or placebo, once on Study Day 0, again on Study Day 28, and again on Study Day 280.
    Intervention: Biological: AERAS-402
  • Experimental: Group 4 - Dose Finding Group 2
    These additional 96 subjects will be randomized (1:1:1:1) in a parallel design to receive two doses of either AERAS-402 (1.5 x 1010, 3.0 x 1010, or 1.0 x 1011 vp) or placebo, once on Study Day 0 and again on Study Day 28.
