A Phase 3, Randomized, Double-blind, Parallel-group Trial to Evaluate the Lot Consistency, Immunogenicity, and Safety of AV7909 for Postexposure Prophylaxis of Anthrax in Healthy Adults

Emergent BioSolutions·interventional·Posted Mar 18, 2019·Updated May 6, 2026

In Brief

A Phase 3 clinical trial evaluating AV7909 and BioThrax for Anthrax. Completed, enrolled 3,689 participants across 35 sites.

Detailed Summary

This study is designed to evaluate the lot consistency (using three consecutively manufactured lots), safety, and ability of the AV7909 anthrax vaccine to generate an immune response in healthy adults and compare the response to that induced by the currently licensed vaccine, BioThrax®, (Anthrax Vaccine Adsorbed; AVA) for post-exposure of anthrax disease.

Interventions

AV7909biological

AV7909 consists of Anthrax Vaccine Adsorbed (AVA) drug substance and CPG 7909 adjuvant. AVA drug substance in AV7909 is similar in composition and manufactured using the same process as commercial BioThrax® vaccine. BioThrax is licensed for post-exposure prophylaxis of anthrax disease. CPG 7909 is an immunostimulatory synthetic oligodeoxynucleotide that functions as an adjuvant. It is designed to induce an enhanced immune response.

BioThraxbiological

BioThrax vaccine (Anthrax Vaccine Adsorbed; AVA) is licensed for post-exposure prophylaxis of anthrax disease.
