A Phase I Study to Evaluate Safety and Immunogenicity of AERAS 404 Administered in Adults

A Phase I Randomized Placebo-Controlled, Double-Blind Study to Evaluate Safety and Immunogenicity of AERAS 404 When Administered as Different IC31 Adjuvant Amounts With Different AERAS-404 (HyVac4) Antigen Amounts in HIV-Negative BCG-Vaccinated Adults Without Evidence of Tuberculosis Infection

• Status: Completed
• Phase: Phase 1
• Study type: Interventional
• Enrollment: 60 (actual)
• Sponsor: Aeras · Academic / Other
• Sex: All
• Age: 18 Years – 45 Years
• Healthy volunteers: Accepted

Summary

This Phase I study will be conducted as a randomized, double-blind, dose-escalation study in five groups of healthy adult male and female subjects who are BCG-vaccinated, HIV-negative, and have no evidence of tuberculosis infection. Since BCG-vaccinated individuals are the target population for which AERAS 404 might be indicated, AERAS 404 will be administered to individuals already vaccinated with BCG

Detailed description

Sixty subjects will be sequentially enrolled into one of five study groups (i.e., Group 1, Group 2, Group 3, Group 4, or Group 5) with 10 subjects per group in Groups 1-4 and 20 subjects in Group 5. Within each study group, subjects will be randomized to a treatment assignment of either AERAS-404 or placebo control at a ratio of 4:1 (Groups 1-4) or two different dose amounts of AERAS-404 or placebo control at a ratio of 9:9:2 (Group 5) administered by intramuscular injection on Study Day 0 and Study Day 56. The principal investigator will determine an appropriate interval between the vaccinations such that the entire group is not dosed at the same time. All subjects will receive the same treatment on Study Day 0 as they receive on Study Day 56. All subjects will be followed for safety and immunogenicity evaluations for 182 days. A total of eleven clinic visits are planned (excluding screening) for all subjects

Interventions

Type	Name	Description
BIOLOGICAL	AERAS-404	AERAS-404 is comprised of the H4 antigen, a fusion protein of Mycobacterium tuberculosis antigens 85B and TB10.4; and IC31 adjuvant, a combination of a leucine-rich peptide and a synthetic oligonucleotide.
BIOLOGICAL	Placebo	Sterile buffer containing 10 mmol Tris and 169 mmol of NaCl in 0.8 mL of aqueous solution. This is the identical buffer solution in which H4 and IC31 are formulated.
