Aquestive Therapeutics Reports Positive Topline Data from Part 1 of EPIPHAST Trial Evaluating AQST-109 Epinephrine Oral Film
WARREN, N.J., Feb. 25, 2022 (GLOBE NEWSWIRE) -- Aquestive Therapeutics, Inc. (NASDAQ: AQST), a pharmaceutical company advancing medicines to solve patients’ problems with current standards of care and provide transformative products to improve their lives, today announced positive topline results from Part 1 of the EPIPHAST study for its AQST-109 epinephrine oral film. Part 1 showed that key pharmacokinetic measures were aligned with previous favorable results for AQST-109 and that the product was well tolerated with no serious adverse events. A lead candidate is currently being evaluated in Part 2 of the EPIPHAST study.
EPIPHAST is a randomized, open-label, three-part adaptive design, crossover study in healthy adult subjects comparing the pharmacokinetics and pharmacodynamics of epinephrine delivered via Aquestive’s AQST-109 oral film compared to intramuscular injection of epinephrine. The study is being conducted pursuant to clearance from Health Canada.
In Part 1 of the EPIPHAST study, multiple oral film formulations and dosage strengths of AQST-109 were evaluated. As shown in the figure below, the lead formulation of AQST-109 rapidly reached clinically meaningful blood concentrations when delivered in two different physical configurations, with a median Tmax of 13.5 minutes and 22.5 minutes, respectively. Part 1 also demonstrated arithmetic mean maximum concentrations (Cmax) of 771 pg/mL and 580 pg/mL for the two configurations, or geometric mean Cmax values of 258pg/mL and 268pg/mL for the two configurations, respectively. These geometric mean Cmax and median Tmax values are consistent with those previously reported for approved injectable epinephrine devices such as EpiPen®.
As shown below, the healthy volunteers were also exposed to a 0.5mg intramuscular injection (IM) of epinephrine, allowing for a comparison with the pharmacokinetics, safety, and tolerability of the higher end of the approved dosage range of epinephrine, consistent with guidance received from the U.S. Food and Drug Administration (FDA) in a written response to the company’s pre-Investigational New Drug (pre-IND) submission.
The findings show that these two configurations of the selected AQST-109 formulation can deliver clinically meaningful blood concentrations of epinephrine sooner than that observed with the higher dose of epinephrine intramuscular injection, and in line with existing epinephrine autoinjectors, and without concerns for safety or tolerability.
“We are very pleased with the results from the first part of this study. We again showed pharmacokinetic results for AQST-109 that demonstrate delivery of epinephrine with the speed and absorption necessary for a rescue product,” said Keith Kendall, Chief Executive Officer of Aquestive. “With so many patients, for a variety of reasons, not having their rescue medication where they need it, when they need it, we believe AQST-109 can significantly improve how patients and caregivers manage anaphylaxis and look forward to our continued development in the next part of the EPIPHAST study.”
“Anaphylaxis is a disease state that has faced a lack of innovation for decades. Epinephrine has been in use for more than a century, yet epinephrine auto-injectors are often underutilized due to various factors, including needle phobia, delayed administration, and failure to carry,” said John Oppenheimer, M.D., FAAAAI, Clinical Professor of Medicine at UMDNJ Rutgers, Pulmonary and Allergy Associates NJ. “AQST-109 shows promise as a novel alternative for the treatment of anaphylaxis, given the small size, portability, and needleless delivery of the product. I look forward to further evaluation of this investigational medicine.”
Aquestive has commenced Part 2 of the EPIPHAST study and expects to report topline results in the first half of 2022. Part 2 is a randomized, crossover design comparing AQST-109 12mg to epinephrine IM 0.3mg.
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. 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.
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.
