- FDA Acceptance of Libervant™ (diazepam) Buccal Film NDA for treatment of seizure clusters in patients between two and five years of age
- Prescription Drug User Fee Act (PDUFA) target goal date set for April 28, 2024
WARREN, N.J., Sept. 11, 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 announced acceptance by the U.S. Food and Drug Administration (FDA) of the Company’s NDA for Libervant™ (diazepam) Buccal Film in pediatric patients between two and five years of age and the assignment of a PDUFA goal date of April 28, 2024.
Aquestive’s NDA 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 has been accepted by the FDA. Diastat® (diazepam) Rectal Gel is the only treatment currently available to this patient population for this indication. 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 Libervant is currently under an orphan drug block to market access until January 2027.
“The FDA’s acceptance of our most recent filing for Libervant is another step forward in bringing this important treatment option to patients,” said Daniel Barber, Chief Executive Officer of Aquestive. “When it comes to the treatment of seizure clusters in pediatric patients with epilepsy five years of age and under, physicians and caregivers have limited options. We believe Libervant, as an oral alternative to existing device-based products, will be well-received by this patient population, if approved with market access.”
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, acute repetitive seizures) 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 between two and five years of age is subject to FDA approval, including for U.S. market access.
