Aquestive Therapeutics to Present Positive Data from Pharmacokinetic and Pharmacodynamic Studies for AQST-109 Epinephrine Sublingual Film at American Academy of Allergy, Asthma, and Immunology (AAAAI) Annual Meeting

WARREN, N.J., Feb. 21, 2023 (GLOBE NEWSWIRE) -- Aquestive Therapeutics, Inc. (NASDAQ: AQST) (the “Company” or “Aquestive”), a pharmaceutical company advancing medicines to solve patients’ problems with current standards of care and provide transformative products to improve their lives, today announced that four late breaking posters recapping the positive data from pharmacokinetic and pharmacodynamic studies of AQST-109 epinephrine sublingual film will be presented at the American Academy of Allergy, Asthma, and Immunology (AAAAI) annual meeting, which will be held from February 24-27 in San Antonio, Texas.

“We are excited to share the positive results from our two completed AQST-109 pharmacokinetic and pharmacodynamic studies at the upcoming AAAAI Conference,” said Dan Barber, Aquestive’s President and Chief Executive Officer. “We look forward to engaging with leaders in the allergy community and providing insights into how our therapeutic candidate has the potential to provide an important advancement for the treatment of acute allergic reactions, if approved by the FDA.”

“Collectively, the AQST-109 studies presented at the 2023 AAAAI add to an accumulating body of favorable evidence indicating that epinephrine delivered via sublingual film results in a rapid onset (i.e., Tmax) and an early, robust increase in other pharmacokinetic and pharmacodynamic parameters used to measure epinephrine efficacy,” stated John Oppenheimer, M.D., FAAAAI, Clinical Professor of Medicine at UMDNJ Rutgers, Pulmonary and Allergy Associated NJ. “The newly presented data also indicate that AQST-109 shows promise as a viable alternative for the management of anaphylaxis.”

About Anaphylaxis
Anaphylaxis is a serious systemic hypersensitivity reaction with rapid onset and potentially fatal. As many as 49 million people in the United States are at chronic risk for anaphylaxis. Lifetime prevalence is at least 5%, or more than 16 million people in the United States. Direct costs of anaphylaxis have been estimated at $1.2 billion per year, with direct expenditures of $294 million for epinephrine, and indirect costs of $609 million. The frequency of hospital admissions for anaphylaxis has increased 500–700% in the last 10–15 years. 52% of patients, who previously experienced anaphylaxis, had never received an epinephrine autoinjector prescription, and 60% did not have an autoinjector currently available. The most common causes of anaphylaxis are foods (such as peanuts), venom from insect stings, and medications. Epinephrine injection is the current standard of treatment intended to reverse the severe manifestation of anaphylaxis, which may include skin rash, throat swelling, respiratory problems, gastrointestinal distress, and loss of consciousness.

About AQST-109
AQST-109 is a polymer matrix-based epinephrine prodrug administered as a sublingual film that is applied under the tongue for the rapid delivery of epinephrine. The product is similar in size to a postage stamp, weighs less than an ounce, and begins to dissolve on contact. No water or swallowing is required for administration. The packaging for AQST-109 is thinner and smaller than an average credit card, can be carried in a pocket, and is designed to withstand weather excursions such as exposure to rain and/or sunlight.
