"The data being presented clearly show NasoVAX’s potential as a safe, effective, and durable flu vaccine," said
About NasoVAX
NasoVAX, an intranasally administered recombinant influenza vaccine, uses an adenovector to achieve expression of the influenza antigen in the target cell, thereby potentially stimulating a broader immune response than traditional influenza vaccines. Our Phase 2a trial evaluating NasoVAX indicated that the vaccine was well-tolerated at all doses tested. Additionally, the achievement of 100% seroprotection and statistically significant increases in mucosal antibody at two of the three dose levels studied has set NasoVAX apart from other intranasally administered vaccines. Strong T-cell responses were also observed at the highest dose. This combination of serum antibody, mucosal antibody and Tcell responses provides the potential for improved ability to prevent infection and suggests that NasoVAX could have a greater impact on flu symptoms and shedding of the flu virus than currently approved influenza vaccines. As part of the Phase 2 study all subjects were followed for an additional six months after vaccination to assess the durability of the antibody response and approximately half of the subjects from the highest dose group were also evaluated between 12 and 14 months after initial dosing for additional immunogenicity assessment. These new NasoVAX data, obtained from the group of 8 subjects that returned for analysis show that the immune response elicited by NasoVAX remained at seroprotective levels for at least 13 months.
About
Altimmune is a clinical-stage immunotherapeutics company focused on the development of products to stimulate robust and durable immune responses for the prevention and treatment of disease. HepTcell is a synthetic peptide immunotherapeutic candidate designed to break immune tolerance in chronic Hepatitis B infection. ALT-702, a TLR7/8 agonist conjugate, is a tumor immunostimulant product candidate that has the potential to safely elicit or improve immune responses in a variety of cancer indications. NasoVAX, our influenza vaccine candidate, has unique characteristics that stimulate multiple arms of the immune system and offers the potential to stop infection and the spread of flu, while being easier to administer through an intranasal spray. NasoShield is a next-generation intranasal anthrax vaccine candidate that is designed to provide more rapid and stable protection than the only approved anthrax vaccine. By leveraging the complementary attributes of its proprietary technology platforms, Altimmune is able to design and develop immunotherapeutic products tailored to address a wide range of disease indications including both acute and chronic infections and cancer.
