Researchers Present New Positive Interim Data on Appili Therapeutics’ ATI-1701 Biodefense Program at 2019 Chemical and Biological Defense Science & Technology Conference

New data demonstrate durable protective response for Appili’s vaccine candidate against Francisella tularensis, a Category A pathogen and potential biological weapons threat

Presentation provides additional safety and efficacy data supporting use of ATI-1701 as a medical countermeasure, supports ongoing development under U.S. Food and Drug Administration’s medical countermeasure development guidelines

HALIFAX, Nova Scotia--()--Appili Therapeutics Inc. (TSXV: APLI) (the Company or Appili), a biopharmaceutical company focused on anti-infective drug development, today announced that Dr. Carl Gelhaus, Senior Program Manager of the Medical Countermeasures Division at MRIGlobal, will present positive interim data on Appili’s ATI-1701 program at the Chemical and Biological Defense Science & Technology Conference (CBD S&T). The conference is being held from November 18-21 at the Duke Energy Convention Center in Cincinnati, Ohio.

The poster presentation at CBD S&T will summarize the latest findings from the ongoing preclinical study of ATI-1701, which showed complete (100%) protection 90 days after vaccination from a lethal exposure to the pathogen Francisca tularensis. This time period is the longest vaccine protection period tested to date in this model. Researchers will conduct an additional evaluation of vaccine efficacy up to 365 days in the same model in H1 2020. The U.S. Defense Threat Reduction Agency (DTRA), an arm of the U.S. Department of Defense (DOD), is funding this trial. MRIGlobal is managing the study under the DTRA contract HDTRA1-16-C-0028.

Together with our partners at the DOD, MRIGlobal, and the National Research Council of Canada, we are greatly encouraged by results from the 90-day vaccine challenge study,” said Kevin Sullivan, CEO of Appili Therapeutics. “Although results are preliminary, they add to a growing body of evidence supporting advanced development of ATI-1701. We look forward to sharing the 365-day challenge results next year, and working with our biodefense partners to potentially produce the first FDA-approved vaccine for the prevention of tularemia.”

​Presentation details are as follows:

Title: Development of Francisella Tularensis SCHU S4 DeltaclpB as a Vaccine for the Prevention of Pneumonic Tularemia in the Warfighter
Session: Medical Countermeasures in the Context of a Layered Medical Defense
Date: Wednesday, November 20, 2019
Time: 4:00 p.m. – 6:00 p.m. ET

About ATI-1701

Appili is developing ATI-1701 as a vaccine to combat Francisella tularensis, which the U.S. National Institutes of Health (NIH) defines as a Category A pathogen (an organism that poses the highest risk to national security and public health). As it is 1,000 times more infectious than anthrax, experts consider the aerosolized form to have a high potential use in a bioterrorist attack.1 Several countries may already have operational weapons programs leveraging this pathogen, making the need for a vaccine to counter this biological weapons threat exceedingly important.2
