Altimmune was awarded a contract valued at up to $120.2 million over five years from the U.S. Biomedical Advanced Research and Development Authority (BARDA) to fund the clinical development of NasoShield, its first-in-class anthrax vaccine candidate. Under BARDA contract HHSO100201600008C, Altimmune has been awarded $14.3 million under the base contract to fund its Phase 1 trial for NasoShield, and options to receive up to an additional $105.9 million to fund further preclinical, clinical and manufacturing development activities.   

NasoShield has been supported by BARDA as a development stage medical countermeasure product and is designed to provide rapid, stable protection after one intranasal administration. In a head-to-head comparison with the existing approved anthrax vaccine in a gold-standard animal model, a single intranasal dose of NasoShield showed complete protection from inhalation anthrax and was non-inferior to multiple doses of the existing approved anthrax vaccine while providing for a more rapid and stable immune response.

“We are pleased to receive this continued validation of our RespirVec platform and BARDA’s support as we advance NasoShield into clinical development,” said Bill Enright, chief executive officer, Altimmune. “Our anthrax vaccine candidate has the potential to provide more rapid, stable and durable protection from a single intranasally administered dose based on preclinical studies. We remain on track to file an IND with the FDA and commence a Phase 1 trial in the second half of 2017.”

The initial award under the BARDA contract will cover the GMP manufacture and the Phase 1 trial. The remainder of the five-year contract is expected to encompass a dose-selection Phase 1b study; scale-up in manufacturing; non-clinical studies; Phase 2 studies for immunogenicity, effectiveness and interactions with antibiotics; regulatory efforts; and formulation development to improve stability.
