GAITHERSBURG, MD, June 1, 2020 (GLOBE NEWSWIRE) -- Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced the U.S. Food and Drug Administration (FDA) has authorized the Company to proceed with a clinical trial of T-COVID, an investigational agent for the treatment of early COVID-19. Patient enrollment in the Phase 1/2 clinical trial is expected to commence in June, with data readout anticipated in Q4 2020.
T-COVID is based on the same replication-deficient adenovirus 5 (RD-Ad5) vector technology behind Altimmune’s intranasal vaccine candidates, which include NasoVAX for influenza, NasoShield for anthrax, and AdCOVID for COVID-19, but it acts through a different mechanism. In preclinical studies sponsored by the National Institute of Allergy and Infectious Diseases, intranasal administration of RD-Ad5 vectors modulated the innate immune response to lethal challenge with a respiratory virus in mice and protected them from death. The immunomodulatory effects resulted in significantly decreased cellular inflammation and lower concentrations of IL-6 and other inflammatory cytokines in the lungs of treated animals compared to controls.
