Secondary Outcome Measures

Immunogenicity of AERAS-402 Based on the Percentage of CD4 Cells of Participants in the "on TB Treatment" Stratum
Assessment of immune response to AERAS-402 was based on the percentage of CD4 and CD8 T cells producing any combination of three cytokines (IFN-γ, TNF-α, and/or IL-2) following stimulation with mycobacterial peptide pools derived from and representing the entire amino acid sequences of mycobacterial antigens Ag85A, Ag85B, and TB10.4. Responses were measured by the intracellular cytokine staining (ICS) assay using flow cytometry.

5. Study Description

Brief Summary
This was a double-blind, randomized, placebo-controlled dose-escalation study in adults recently treated for pulmonary TB. The dose of AERAS-402 increased in successive dose groups. Enrollment into a dose group was sequential. Enrollees were stratified based on time from the start of TB treatment. The "on-TB-treatment" stratum started TB treatment between 1 and 4 months (30 to 120 calendar days) prior to Study Day 0. The "post-TB-treatment" stratum started TB treatment at least 12 months (360 calendar days) prior to Study Day 0. Subjects were randomized to receive a placebo or AERAS-402 vaccine. In Dose Groups 1 and 2, subjects were randomized to receive a single injection of AERAS-402 or placebo. Dose Group 3 subjects were randomized to receive two injections on study day 0 and study day 42 of AERAS-402 or placebo.
Detailed Description
A total of 72 subjects were randomized into the study. Subjects were stratified, based on time from the start of TB treatment, into the 'on-TB-treatment' stratum (TB treatment started between 1 and 4 months prior to Study Day 0) or the 'post-TB-treatment' stratum (TB treatment started at least 12 months before Study Day 0). In the on-TB-treatment stratum, 36 subjects were randomized to receive AERAS-402 or placebo as follows: 1 or 2 doses of placebo (N=5); 1 dose of AERAS-402 at 3 x 10^8 vp (N=5) or 3 x 10^9 vp (N=10), or 2 doses of AERAS-402 at 3 x 10^10 vp (N=16). In the post-TB-treatment stratum, 36 subjects were randomized to receive AERAS-402 or placebo as follows: 1 or 2 doses of placebo (N=6); 1 dose of AERAS-402 at 3 x 10^8 vp (N=5) or 3 x 109 vp (N=10), or 2 doses of AERAS-402 at 3 x 10^10 vp (N=15).
