Anaphylm pharmacokinetic results unaffected by oral cavity exposure to liquids of different temperatures and pH Remains on track to complete Anaphylm supportive clinical studies and expects to request pre-NDA meeting with FDA in the third quarter 2024 Continues to anticipate filing a New Drug Application (NDA) shortly after completion of its pediatric study of Anaphylm WARREN, N.J., June 25, 2024 (GLOBE NEWSWIRE) -- Aquestive Therapeutics, Inc. (NASDAQ: AQST) (“Aquestive” or the “Company”), a pharmaceutical company advancing medicines to bring meaningful improvement to patients' lives through innovative science and delivery technologies, today released positive topline pharmacokinetic (PK) data from the temperature / pH study of its product candidate Anaphylm™ (epinephrine) Sublingual Film. Anaphylm is the Company’s first and only orally administered epinephrine prodrug product candidate under development for the treatment of severe life-threatening allergic reactions, including anaphylaxis. “The positive topline data from this study reinforce that Anaphylm has the potential to be seamlessly integrated into patients’ daily lives,” said Daniel Barber, President & Chief Executive Officer of Aquestive. “A recent independently conducted survey reported that 100% of patients and caregivers who participated in the survey indicated they would not return home to retrieve an autoinjector, if forgotten.1 Breaking this concerning cycle of not carrying epinephrine, the only first-line treatment for anaphylaxis, requires a product that is easy to remember, easy to carry, and easy to use even after consumption of a beverage or food. We believe Anaphylm possesses these essential attributes and has the potential to transform the lives of people at risk for severe and life-threatening allergic reactions, if approved by the FDA.” The single-dose, five-period, randomized crossover study was designed to compare the PK and pharmacodynamics (PD) of Anaphylm just after consuming normal water (hot, cold, and room temperature), lemon water, and baking soda water. The primary PK parameters were the maximum amount of epinephrine measured in plasma (Cmax) and exposure, or the area under the curve (AUC), at various times after dosing, in 30 healthy adult subjects. Topline PK data from the study showed no statistically significant difference in PK results based on changes in temperature and pH. The most consumed beverages, such as soda, milk, coffee, and juice, have acidity between lemon water and normal water. While not statistically significant, alkaline substances like baking soda showed a somewhat higher absorption level than room-temperature water. The table below provides the ratio of Cmax and AUC 0-60min following administration of Anaphylm under various test states when compared to room temperature water. Test Condition* Cmax (test condition / room temperature water) AUC 0-60min (test condition / room temperature water) Cold water 106% 98% Hot water 104% 107% Lemon water (target pH: 3) 98% 99% Baking soda water (target pH:8) 123% 132% *Topline pharmacodynamics (PD) data expected to be available for Q2 earnings update. “Patients experiencing an allergic reaction must have confidence that their rescue medication will provide sufficient medicine as quickly as possible and without fail,” said Eleanor Garrow-Holding, President & CEO of Food Allergy & Anaphylaxis Connection Team (FAACT). “We are pleased to see that the data released by Aquestive today supports this need. We continue to believe it is critical for patients, their caregivers, and providers to have innovative treatments, like Anaphylm, to improve care and outcomes if experiencing a severe allergic reaction, including anaphylaxis.” The Company’s remaining supportive studies, inclusive of the self-administration study and the oral allergy syndrome (OAS) challenge study, are all underway. The self-administration study's dosing is expected to conclude in the second quarter of 2024, and the OAS challenge study's initial dosing is expected to occur in July 2024. The table below indicates the remaining clinical studies anticipated before submission of the New Drug Application (NDA) for Anaphylm. Anticipated Timing** Pivotal PK Studies Supportive PK Studies FDA Meetings / Actions Completed in 2024 Phase 3 PK Study (including repeat dose) Temperature/pH PK Study Type C Meeting Currently Underway Self-administration PK Study Oral allergy syndrome (OAS) Challenge Study Remaining in 2024 Pediatric Study Pre-NDA Meeting FDA filing **Timeline does not include chemistry, manufacturing, and controls (CMC), preclinical and human factors activities. “I am incredibly proud of the rapid progress made by the team,” concluded Dan Barber. “We anticipate that, before the end of the third quarter, the adult studies that we believe are necessary for a robust NDA filing will be complete. We plan on requesting a pre-NDA meeting with the FDA upon receipt of topline data. We continue to anticipate conducting our pediatric study for Anaphylm in the fourth quarter 2024, if agreed upon with the FDA, and filing shortly thereafter. We remain committed to providing a novel solution that addresses unmet needs for the severe allergy community.” 1Source: About Anaphylaxis Anaphylaxis is a serious systemic hypersensitivity reaction with that is rapid in onset and potentially fatal. As many as 49 million people in the United States are at chronic risk for anaphylaxis. Lifetime prevalence is at least 5%, or more than 16 million people in the United States. Direct costs of anaphylaxis have been estimated at $1.2 billion per year, with direct expenditures of $294 million for epinephrine, and indirect costs of $609 million. The frequency of hospital admissions for anaphylaxis has increased 500–700% in the last 10–15 years. Of patients who previously experienced anaphylaxis, 52% had never received an epinephrine auto-injector prescription, and 60% did not have an auto-injector currently available. The most common causes of anaphylaxis are foods (such as peanuts), venom from insect stings, and medications. Epinephrine injection is the current standard of treatment intended to reverse the severe manifestation of anaphylaxis, which may include skin rash, throat swelling, respiratory difficulty, gastrointestinal distress, and loss of consciousness. About Anaphylm™ Anaphylm™ (epinephrine) Sublingual Film has the potential to be the first and only non-invasive, orally delivered epinephrine for the treatment of severe life-threatening allergic reactions, including anaphylaxis, if approved by the United States Food and Drug Administration (FDA). Anaphylm is a polymer matrix-based epinephrine prodrug candidate product. 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 “Anaphylm” for AQST-109 has been conditionally approved by the FDA. Final approval of the Anaphylm proprietary name is conditioned on FDA approval of the product candidate.

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 “Anaphylm” tradename for AQST-109 has been conditionally approved by the United States Food and Drug Administration (FDA). Final approval of the Anaphylm proprietary name is conditioned on FDA approval of the product candidate. In March 2024, Aquestive reported positive topline clinical data for the two-part, Phase 3, single-center, open-label, randomized study, which was designed to compare the pharmacokinetics (PK) and pharmacodynamics (PD) of single and repeat doses of Anaphylm versus single and repeat doses of the epinephrine intramuscular (IM) injection and epinephrine autoinjectors (EpiPen® and Auvi-Q®) in healthy adult subjects. The Company met all predefined primary and secondary PK endpoints in this study. About Libervant™ (diazepam) Buccal FilmLibervant™ (diazepam) Buccal Film is the first and only FDA approved orally administered rescue product for the treatment of seizure clusters in patients ages two to five. In April 2024, the FDA approved Libervant for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) that are distinct from a patient’s usual seizure pattern in patients with epilepsy between 2 to 5 years of age. Libervant for patients between the ages of two to five years old is immediately available in 5mg, 7.5mg, 10mg, 12.5mg, and 15mg, and the Company is currently able to accept and fill non-Medicaid prescriptions for these pediatric patients. The New Drug Application (NDA) for Libervant for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) in patients twelve years of age and older was tentatively approved by the FDA in August 2022 and is currently subject to an orphan drug market exclusivity block until January 2027 based on an FDA approved nasal spray product of another company. Important Safety InformationDo not give Libervant™ to your child if your child is allergic to diazepam or any of the ingredients in Libervant or has an eye problem called acute narrow angle glaucoma. What is the most important information I should know about Libervant? Libervant is a benzodiazepine medicine. Taking benzodiazepines with opioid medicines, alcohol, or other central nervous system (CNS) depressants (including street drugs) can cause severe drowsiness, breathing problems (respiratory depression), coma, and death. Get emergency help right away if any of the following happens: shallow or slowed breathing,breathing stops (which may lead to the heart stopping),excessive sleepiness (sedation). Do not allow your child to drive a motor vehicle, operate heavy machinery, or ride a bicycle until you know how taking Libervant with opioids affects your child. Risk of abuse, misuse, and addiction. Libervant is used in children 2 to 5 years of age. The unapproved use of Libervant has a risk for abuse, misuse, and addiction, which can lead to overdose and serious side effects including coma and death.Serious side effects including coma and death have happened in people who have abused or misused benzodiazepines, including diazepam (the active ingredient in Libervant). These serious side effects may also include delirium, paranoia, suicidal thoughts or actions, seizures, and difficulty breathing. Call your child’s healthcare provider or go to the nearest hospital emergency room right away if you get any of these serious side effects. Your child can develop an addiction even if your child takes Libervant as prescribed by your child’s healthcare provider.Give Libervant exactly as your child’s healthcare provider prescribed.Do not share Libervant with other people.Keep Libervant in a safe place and away from children. Physical dependence and withdrawal reactions. Libervant is intended for use if needed in order to treat higher than usual seizure activity. Benzodiazepines, including Libervant, can cause physical dependence and withdrawal reactions, especially if used daily. Libervant is not intended for daily use. Do not suddenly stop giving Libervant to your child without talking to your child’s healthcare provider. Stopping Libervant suddenly can cause serious and life-threatening side effects, including, unusual movements, responses, or expressions, seizures that will not stop (status epilepticus), sudden and severe mental or nervous system changes, depression, seeing or hearing things that others do not see or hear, homicidal thoughts, an extreme increase in activity or talking, losing touch with reality, and suicidal thoughts or actions. Call your child’s healthcare provider or go to the nearest hospital emergency room right away if your child gets any of these symptoms.Some people who suddenly stop benzodiazepines have symptoms that can last for several weeks to more than 12 months including, anxiety, trouble remembering, learning, or concentrating, depression, problems sleeping, feeling like insects are crawling under your skin, weakness, shaking, muscle twitching, burning, or prickling feeling in your hands, arms, legs or feet, and ringing in your ears.Physical dependence is not the same as drug addiction. Your child’s healthcare provider can tell you more about the differences between physical dependence and drug addiction. Do not give your child more Libervant than prescribed or give Libervant more often than prescribed. Libervant can make your child sleepy or dizzy and can slow your child’s thinking and motor skills.
