[PRESS RELEASE]

Aquestive Therapeutics Reports Positive Results from Final Two Arms of EPIPHAST Trial Supporting Performance and Real-World Functionality of AQST-109 Epinephrine Oral Film

  • Study results for the sublingual administration of AQST-109 epinephrine oral film after consuming a peanut butter sandwich demonstrates consistent Tmax of 12 minutes.
  • Study results for swallowing AQST-109 whole immediately with water showed an unexpectedly high level of gastrointestinal absorption.
  • EPIPHAST II, a crossover study, is now underway, comparing AQST-109 to epi 0.3mg IM injection (repeat dose) and AQST-109 to EpiPen® 0.3mg (single dose)


WARREN, N.J., July 11, 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 the final two arms of Part 3 of the EPIPHAST study for its AQST-109 epinephrine oral film.

The purpose of Part 3 was to continue to study the administration of the film under a variety of conditions to further characterize its pharmacokinetics, pharmacodynamics, and safety. The final two arms were designed to assess the impact of (1) administering the film sublingually two minutes after consuming a peanut butter sandwich and (2) swallowing the film whole immediately with water.

The data showed that administering the film sublingually two minutes after consuming a peanut butter sandwich had no statistical impact on the resulting pharmacokinetics when compared to previous data from the initial Part 3 dataset. The medium time to maximum concentration (Tmax) and partial area under the curve (AUC) results were comparable and the time to reach Tmax remained 12 minutes when sublingually administered after consumption of a peanut butter sandwich. The geometric mean maximum concentration, or Cmax of 286 pg/mL was also comparable to previous data from Part 3.

The data also showed that swallowing the film whole immediately with water unexpectedly resulted in significant absorption of epinephrine. This finding has the potential of further de-risking the development program by lowering the risks associated with patient non-compliance to the administration instructions in a real-world setting. The Cmax was 313 pg/mL and the Tmax, while slower than the sublingual administration was significantly faster than the epinephrine 0.3mg IM injection from Parts 1 and 2 of the EPIPHAST study.

“We are thrilled to conclude and share the data from Part 3 of the EPIPHAST study further demonstrating AQST-109’s strong and differentiated pharmacokinetic performance under a variety of conditions which now includes dosing the sublingual film after eating a peanut butter sandwich and swallowing the film whole immediately with water,” said Dan Barber, Chief Executive Officer of Aquestive. “It is very promising that AQST-109 continues to perform well in challenging and less than ideal circumstances, further validating performance and real-world functionality.”

“Epinephrine is unquestionably the cornerstone of anaphylaxis management, yet studies have found that epinephrine is significantly underutilized during an anaphylactic emergency,” said David Bernstein, M.D., Professor: Division of Immunology, Allergy and Rheumatology University of Cincinnati. “As an allergist who treats patients at risk for anaphylaxis, I have witnessed the underutilization of epinephrine to be based on a number of factors, including fear of needles or the patient simply not having an epinephrine auto-injector with them when they need it. I am pleased to see the accumulating, positive data on AQST-109. These latest results from the EPIPHAST trial continue to show that sublingual administration of epinephrine has the potential to deliver epinephrine in a safe and effective way and may also make it easier for patients to carry and more quickly administer the medicine during a life-threatening allergic event.”

EPIPHAST was 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 was being conducted pursuant to clearance from Health Canada.

Aquestive received a written response from the U.S. Food and Drug Administration (FDA) in December 2021 to its Pre-Investigational New Drug Application (IND) meeting submission confirming that the development of AQST-109 for the treatment of anaphylaxis under the 505(b)(2) approval pathway is acceptable. Aquestive opened the IND for AQST-109 after receiving FDA clearance in February 2022. AQST-109 met the regulatory criteria for Fast Track designation as announced in March 2022.

Aquestive is conducting its EPIHPHAST II study comparing AQST-109 to epi 0.3mg IM injection (repeat dose) and AQST-109 to EpiPen 0.3mg (single dose). This data, along with the data from the complete EPIPHAST study, will be the basis for the End-of-Phase 2 meeting with the FDA that the Company plans to request in the fourth quarter 2022.

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.
