Aquestive Therapeutics Announces Successful Completion of Phase 1 Trial for AQST-108 (Sublingual Film Formulation Delivering Systemic Epinephrine)

- Represents Significant Proof-of-Concept Milestone for Sublingual Epinephrine Pipeline Product -

WARREN, N.J., Sept. 30, 2019 (GLOBE NEWSWIRE) -- Aquestive Therapeutics, Inc. (NASDAQ: AQST), a specialty pharmaceutical company focused on developing and commercializing differentiated products to solve therapeutic problems, today announced the successful completion of its Phase 1 dose escalation proof-of-concept study in healthy subjects for AQST-108.  AQST-108 is a “first of its kind” oral sublingual film formulation delivering systemic epinephrine that is in development for the treatment of anaphylaxis using Aquestive’s proprietary PharmFilm® technologies.

Importantly, the data demonstrated that AQST-108:

    • achieved similar ranges of mean values of maximum concentration (Cmax) and time to reach maximum concentration (Tmax) to that reported for injectables EpiPen® and Auvi-Q®
    • provided a greater total exposure (AUC0-t; area under the curve) than that reported for EpiPen and Auvi-Q
    • had less interpatient variability when compared to degree of variation (CV%) data reported for EpiPen and Auvi-Q
    • was well tolerated, with no study participants discontinuing participation due to an adverse event

Based on the results of this proof-of-concept study, Aquestive is in the process of scheduling a pre-IND meeting with the U.S. FDA.

“We’re very pleased with the proof-of-concept data that demonstrated our ability to deliver systemic epinephrine via our PharmFilm formulation,” said Keith J. Kendall, Chief Executive Officer of Aquestive. “Anaphylaxis is a serious condition that impacts a large patient population.  The only options currently available to patients require an injection.  We believe we have the technology that can bring meaningful innovation and positive change for patients. We plan on meeting with the U.S. FDA as soon as possible to discuss the further development of AQST-108 and we are focused on providing the first highly portable, easy-to-administer and anxiety-free oral sublingual film medication to treat this serious condition.”

Anaphylaxis is a potentially life-threatening systemic allergic reaction, with an estimated incidence of 50 to 112 episodes per 100,000 people per year. The frequency of hospital admissions for anaphylaxis has increased 500-700% in the last 10-15 years.1 The most common causes of reactions that can include anaphylaxis are medications, foods (such as peanuts), and venom from insect stings. Epinephrine injection is the current standard of treatment intended to reverse the potentially severe manifestation of anaphylaxis, which may include red rash, throat swelling, respiratory problems, gastrointestinal distress and loss of consciousness.
