Zogenix’s FINTEPLA® (Fenfluramine) Oral Solution Now Available in Germany for the Treatment of Seizures in Dravet Syndrome

• FINTEPLA offers a new treatment option for patients in Germany with Dravet syndrome, a rare, devastating, infant-onset epilepsy marked by frequent seizures, medical emergencies, and developmental impairments
• FINTEPLA was approved by the European Commission in December 2020 based on data from two Phase 3 studies demonstrating it safely and significantly reduced convulsive seizure frequency for Dravet syndrome patients whose seizures were not adequately controlled on their existing medications

EMERYVILLE, Calif., Feb. 01, 2021 (GLOBE NEWSWIRE) — Zogenix (NASDAQ: ZGNX), a global biopharmaceutical company developing rare disease therapies, announced today that FINTEPLA^® (fenfluramine) oral solution is now available in Germany for the treatment of seizures associated with Dravet syndrome in patients aged two years and older, as an add-on therapy to existing anti-epileptic medications. Dravet syndrome is a rare, lifelong epilepsy that begins in infancy and is marked by severe refractory seizures, frequent medical emergencies, significant cognitive and behavioral impairments, and an increased risk of sudden premature death (SUDEP).

“Patients with Dravet syndrome experience severe and often prolonged seizures that are highly resistant to existing anti-convulsant medications. Despite treatment with one or more of the currently available medications, most patients’ seizures are not adequately controlled,” said Dr. Jens Grünert, Medical Director, Zogenix Germany. “With the launch of FINTEPLA in Germany, physicians and caregivers here can now access an urgently needed, effective and generally well-tolerated new treatment option to help reach their goals of reducing the devastating seizures and improving outcomes and quality of life for patients and their families.”

FINTEPLA will be available in Germany starting on 1 February 2021 under a controlled access program requested by the European Medicines Agency. In Germany, physicians will register for an identification number before being able to prescribe FINTEPLA via the following website: www.fenfluramin-wichtige-infos.de/verschreiber. Further details regarding prescribing and patient monitoring requirements can be found on the European Medicines Agency website: https://www.ema.europa.eu/en/medicines/human/EPAR/fintepla.

The approval of FINTEPLA by the European Commission in December 2020 was based on positive safety and efficacy results from two randomized, international, multi-center, placebo-controlled Phase 3 trials (Study 1 and Study 2), as well as data from an interim analysis of a long-term, open-label extension study in 330 Dravet syndrome patients treated up to 3 years. In the studies, most patients given FINTEPLA in addition to their existing regimen of antiepileptic therapies, experienced a statistically significant and clinically meaningful reduction in convulsive seizure frequency. The most commonly reported adverse events that occurred in patients included decreased appetite, diarrhea, pyrexia, fatigue, upper respiratory tract infection, lethargy, somnolence and bronchitis.

About FINTEPLA^®
In 2020, FINTEPLA (fenfluramine) oral solution was approved by the U.S. Food & Drug Administration (FDA), and by the European Commission as an add on therapy to other anti-epileptic medicines, for the treatment of seizures associated with Dravet syndrome in patients aged two years and older. In addition, Zogenix recently reported positive results of a third Phase 3 study of FINTEPLA in Dravet syndrome to support planned registration in Japan, which corroborated the statistically significant and clinically meaningful convulsive seizure reductions seen in earlier multinational Phase 3 studies. FINTEPLA is also being studied for the potential treatment of seizures associated with other rare epilepsies.

About Dravet Syndrome
Dravet syndrome is a rare, devastating and life-long form of epilepsy that generally begins in infancy and is marked by frequent, treatment-resistant seizures, significant developmental, motor, and behavioral impairments, and an increased risk of sudden unexpected death in epilepsy (SUDEP). Affecting one in 15,700 live births in the U.S. and approximately one in 20,000 to 40,000 live births in Europe, most patients follow a course of developmental delay with cognitive, motor and behavioral deficits that persist into adulthood. Dravet syndrome severely impacts quality of life for patients, families and caregivers due to the high physical, emotional, caregiving, and financial burden associated with the disease.

The company’s first rare disease therapy, FINTEPLA^® (fenfluramine) oral solution has been approved by the U.S. FDA and the European Medicines Agency and is in development in Japan for the treatment of seizures associated with Dravet syndrome, a rare, severe lifelong epilepsy. The company has two additional late-stage development programs underway: one for FINTEPLA for the treatment of seizures associated with Lennox-Gastaut syndrome, another rare epilepsy, and one for MT1621, an investigational therapy for the treatment of a rare genetic disorder called TK2 deficiency (being developed through its subsidiary Modis Therapeutics). Zogenix is also collaborating with Tevard Biosciences to identify and develop potential next-generation gene therapies for genetic rare epilepsies.
