Aquestive Therapeutics Announces Positive Topline PK Results from its Pediatric Study and Completes the NDA Submission for Anaphylm™ (epinephrine) Sublingual Film

• Reports positive pharmacokinetic (PK) results from the recently completed pediatric study for Anaphylm™
• Completes submission of its New Drug Application (NDA) for Anaphylm to the FDA; NDA acceptance expected in Q2 2025

WARREN, N.J., April 01, 2025 (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 announced positive topline results from its pediatric study for Anaphylm™ (epinephrine) sublingual film in patients aged seven to seventeen and weighing greater that thirty kilograms with a personal history of allergic reactions. This marks the completion of the Anaphylm clinical program and supports the clinical data needed for the NDA submission. Aquestive has submitted the Anaphylm NDA to the U.S. Food and Drug Administration (FDA) and expects to receive potential acceptance of the NDA during the second quarter of 2025.

"We are extremely pleased with the positive results from our pediatric study, which further validate Anaphylm's potential as the first-ever sublingual film and convenient treatment option for all patients with severe allergic reactions, including anaphylaxis," said Daniel Barber, President and Chief Executive Officer of Aquestive. "These results demonstrate that Anaphylm maintains its consistent PK profile in pediatric patients between the ages of seven and seventeen and weighing greater than thirty kilograms. These data are an important component of the FDA review process and could enable Anaphylm to have a label that includes this pediatric patient population. We continue to prepare for commercial readiness and plan to launch Anaphylm in the first quarter of 2026, if approved by the FDA.”

The pediatric study was a multi-site, single treatment study designed to evaluate the PK, pharmacodynamics (PD), safety, and tolerability of Anaphylm. A total of thirty-two patients completed the study. The PK results were consistent with previous adult studies. Importantly, Anaphylm was shown to be safe and well-tolerated with no serious adverse events (SAEs) reported. Figure 1 below compares the pediatric study results to the previously announced pivotal adult study results.
