Item 7.01.Regulation FD Disclosure.


On June 29, 2021, Altimmune, Inc., or the Company, issued a press release announcing the results of, and an update on, the Phase 1 trial for AdCOVID, the Company’s intranasal COVID-19 vaccine candidate, as well as an update on the Phase 1/2 trial for T-COVID, the Company’s investigational agent for the treatment of early COVID-19.


 A copy of the press release is attached hereto as Exhibit 99.1.


The information in this Item 7.01, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing.


Item 8.01.Other Events.


On June 29, 2021, the Company issued a press release announcing the results of its Phase 1 trial for AdCOVID and the discontinuation of further development of AdCOVID, based in part on the Phase 1 results. The Company also announced that it has terminated further enrollment of its Phase 1/2 trial of T-COVID because of the Company’s inability to enroll subjects in the final cohort as a result of effective rollout in the United States of authorized COVID-19 vaccines and decreasing incidence of disease, which has significantly reduced the number of patients meeting these criteria. The Company is evaluating other development options for the T-COVID program.
