WARREN, N.J., June 29, 2020 (GLOBE NEWSWIRE) -- Aquestive Therapeutics, Inc. (NASDAQ: AQST), a pharmaceutical company focused on developing and commercializing differentiated products that address patients' unmet needs and solve therapeutic problems, announced today that it has submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for pharmacokinetic (PK) clinical trials of its drug candidate AQST-108, 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. The Company intends to initiate its planned PK trials before the year end 2020.

Aquestive plans to initiate its PK clinical trials of AQST-108 in a crossover study to compare the pharmacokinetics and pharmacodynamics of epinephrine administered as sublingual film to that of epinephrine administered as an injection. As proposed by Aquestive and confirmed by the FDA at the pre-IND meeting held in February 2020, the clinical development for AQST-108 will be reviewed under the 505(b)(2) regulatory approval pathway. The FDA acknowledged that there appears to be an unmet medical need among patients who resist the standard of care use of subcutaneous and intramuscular injection in the treatment of anaphylaxis. The Company believes that AQST-108 may potentially address some of those unmet needs.

"As we have committed, we have completed the filing of the IND for AQST-108, which is a significant milestone for this development program. We are on track to commence our PK study before year end," said Keith J. Kendall, Chief Executive Officer of Aquestive. "Anaphylaxis is a serious condition that impacts a large patient population for which there is a significant unmet need. The only options currently available to patients require an injection and, if approved by the FDA, AQST-108 can potentially bring meaningful innovation and positive change for patients. We are focused on providing the first highly portable, easy-to-administer and anxiety-free sublingual film medication to treat this serious condition."

About 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.

The data from the previously completed Phase 1 dose escalation study 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, and was well tolerated, with no study participants discontinuing participation due to an adverse event.

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.
