Altimmune Completes Enrollment in Phase 1b Clinical Trial of NasoShield™, a Single Dose Intranasal Anthrax Vaccine Candidate
The clinical trial has enrolled 42 evaluable healthy subjects to receive intranasally administered NasoShield or placebo and be followed for 6 months following dosing. The primary immunogenicity readouts are the serum antibody response to protective antigen and toxin-neutralizing antibody titer 28 and 56 days after dosing. As with Altimmune’s other vaccine programs, stimulation of a mucosal IgA immune response in the nasal cavity will also be assessed as a potential additional benefit to other immunologic responses. Nasal mucosal immunity, which can play an important role in the body’s defense against respiratory diseases, is best stimulated by the nasal route of vaccine administration.
The NasoShield program is being developed under a contract with the
NasoShield has the potential to be a convenient and simple alternative to the current approved multi-dose anthrax vaccine, as it is intended to confer protection after a single intranasal dose instead of the three-injection regimen required by the only licensed vaccine. Intranasal dosing provides the potential to be administered rapidly and without the need for needles, syringes or trained healthcare personnel in the event of an anthrax incident. In addition, NasoShield’s expected room temperature stability profile may allow for broad distribution of the vaccine without the need for expensive cold-chain logistics, such as refrigeration or freezing.
Earlier this quarter, the Company reported positive preclinical data on AdCOVID, a single dose intranasal COVID-19 vaccine candidate which is derived from the same replication-deficient adenovirus 5 vaccine platform technology as NasoShield. In these preclinical studies performed in collaboration with the
