• Submitted NDA for Libervant™ (diazepam) Buccal Film for treatment of seizure clusters in patients between two and five years of age
• Appointed Carl N. Kraus, M.D. as Chief Medical Officer

WARREN, N.J., June 29, 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 provided an update on recent business developments and announced the appointment of Carl N. Kraus, M.D. as Chief Medical Officer of the Company.

NDA Filing for Libervant for Pediatric Population
Aquestive submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for approval of Libervant™ (diazepam) Buccal Film for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) in patients between two and five years of age. The Company received tentative approval for Libervant for the treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) in patients 12 years of age and older in August 2022, but is currently under an orphan drug block to market access until January 2027. Diastat® (diazepam) Rectal Gel is the only treatment currently available to this patient population for this indication. The Company expects to hear from the FDA on the acceptance of, and issuance of a target action date on, this pediatric NDA within approximately two months.

“We are hopeful that this important subpopulation may benefit from Libervant in the near term,” said Daniel Barber, Chief Executive Officer of Aquestive. “While there is inherent unpredictability in the orphan drug review process, we believe in patient choice and will continue to advocate for patient access to meaningful innovation across all age groups.”

Chief Medical Officer Appointment
“I am very pleased to welcome Carl to the Aquestive team. He brings over two decades of experience in drug development, ranging from discovery through late stage development, as well as a significant medical background,” said Mr. Barber. “His extensive clinical development experience will be invaluable in advancing the Anaphylm® development program as we plan to submit the pivotal study protocol to the FDA. I look forward to working with Carl as we continue to advance and expand our product development pipeline in 2023 and beyond.”

Dr. Kraus commented, “I recognize the potential for Anaphylm to transform the treatment of allergic reactions. Lowering the barriers to epinephrine use via a sublingual film could help many patients with severe allergic reactions. I look forward to joining the Aquestive team as the Company continues to advance this important development program.”

Aquestive named Carl N. Kraus, M.D. as Chief Medical Officer effective June 26, 2023. Dr. Kraus joins the Aquestive team from Aceragen, where he served as Chief Medical Officer from October 2021 to April 2023. Prior to that, Dr. Kraus founded and served as the Chief Executive Officer of Arrevus from January 2017 until the sale of Arrevus to Aceragen in October 2021. He previously served as Chief Medical Officer of Ology Bioservices (formerly Nanotherapeutics), which was acquired by National Resilience. Prior to joining the pharmaceutical industry, Dr. Kraus was a Medical Officer for the Center of Drug Evaluation and Research (“CDER”). Earlier in his career, he held inpatient and outpatient clinical appointments. Dr. Kraus earned his medical doctor degree from Washington University School of Medicine in St. Louis, MO, with post-graduate training in Internal Medicine (University of Chicago) and Infectious Diseases (National Institutes of Health).

About Libervant
Libervant is a buccally, or inside of the cheek, administered film formulation of diazepam, a benzodiazepine intended for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters) that are distinct from a patient’s usual seizure pattern. Aquestive developed Libervant as an alternative to the device-based products currently available for patients with refractory epilepsy, including a rectal gel and nasal spray products. The FDA has granted tentative approval for Libervant for treatment of these epilepsy patients 12 years of age and older, with U.S. market access for Libervant for this age group of patients subject to the expiration of the existing orphan drug market exclusivity of a previously FDA approved drug scheduled to expire in January 2027. The NDA submitted today for Libervant for epilepsy patients aged two to five is subject to FDA approval, including for U.S. market access.

About Anaphylm™
Anaphylm™ (AQST-109) is a polymer matrix-based epinephrine prodrug candidate product 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 Anaphylm 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. The tradename for AQST-109 “Anaphylm” has been conditionally approved by the FDA. Final approval of the Anaphylm™ proprietary name is conditioned on FDA approval of the product candidate.
