Researchers Publish Manuscript on the Prevention and Emergency Response to Tularemia Outbreaks

A review of Russian and English literature suggests that Appili’s biodefense program ATI-1701 may have a role in preventing tularemia in Ukraine

HALIFAX, Nova Scotia, March 12, 2024 (GLOBE NEWSWIRE) -- Appili Therapeutics Inc. (TSX:APLI; OTCPink: APLIF) (the “Company” or “Appili”), a biopharmaceutical company focused on drug development for infectious diseases and biodefense products, today announced a publication in the journal Frontiers in Bacteriology on the prevention of tularemia. Appili’s Director of Non-Clinical Research, Dr. Carl Gelhaus, Ph.D., together with medical doctors from the United States Uniformed Services University of the Health Sciences and Ukrainian researchers published a perspective manuscript “Considerations for prevention of and emergency response to tularemia outbreaks in Ukraine: vaccine involvement”.

“Appili has been developing ATI-1701, a biodefense vaccine, to protect warfighters from tularemia.” said Carl Gelhaus, Ph.D., Director of Non-Clinical Research of Appili Therapeutics. “With the help of our Ukrainian colleagues and U.S. Army physicians, we have assessed the potential risk for tularemia outbreaks in Ukraine, by reviewing the literature of previous wartime outbreaks in Eastern Europe. Many of the conditions for tularemia outbreaks now exist in Ukraine, and their warfighters need protection. We suspected that rodent populations would explode and carry tularemia into war-affected areas. Even as we were preparing the manuscript, “Mouse fever”, an infection of unknown etiology, was reported in news outlets, underscoring the urgency of making sure Ukrainians are protected from the risk of many infectious diseases, including tularemia. The acceptance and publication of this perspective article recognizes that the epidemiological, medical, military, and scientific tularemia experts should prepare to prevent and respond to tularemia outbreaks in wartime Ukraine.”

The perspective manuscript explores the current war in Ukraine and the increased risk for outbreaks of tularemia. Several wartime tularemia outbreaks have been documented, as far back as the Siege of Stalingrad in WWII. Furthermore, F. tularensis was weaponized and stockpiled as an offensive agent, and experts consider tularemia to have a high potential use in a biological weapons attack. Russia administers its own tularemia vaccine, but that vaccine is not available in Ukraine. Furthermore, the legacy Russian vaccine is unlikely to meet the rigorous FDA and EMEA standards for safety and efficacy.
