Zogenix Receives Orphan Drug Designation in the European Union for ZX008 in Lennox Gastaut Syndrome


EMERYVILLE, Calif., March 01, 2017 (GLOBE NEWSWIRE) -- Zogenix, Inc. (NASDAQ:ZGNX), a pharmaceutical company developing therapies for the treatment of orphan and central nervous system (CNS) disorders, today announced that the European Commission (EC) has designated ZX008 (fenfluramine) as an orphan medicinal product for the treatment of Lennox Gastaut Syndrome (LGS), a refractory, debilitating childhood-onset epilepsy. The EC’s approval follows a positive opinion in January from the European Medicine Agency’s (EMA) Committee for Orphan Medicinal Products (COMP).

“This Orphan Drug Designation is an important component in our strategy to evaluate potential expanded uses of ZX008 in other rare and severe epilepsy conditions,” said Stephen J. Farr, Ph.D., President and Chief Executive Officer of Zogenix.  “Compelling preliminary efficacy data from an on-going, open-label Phase 2 study for ZX008 in LGS were presented in December 2016 at the American Epilepsy Society Annual Meeting. Based on these promising results, we intend to move forward with a Phase 3 clinical study for ZX008 in LGS in the second half of 2017.”

Orphan Drug Designation is granted by the EC to drugs that are intended for the treatment of life-threatening or chronically debilitating, rare diseases where no satisfactory treatment of the condition concerned is authorized. If such a treatment exists, then the medicine must be of significant benefit to those affected by the condition. Rare diseases are those defined as having a prevalence of not more than five per 10,000 population in Europe. The Orphan Drug Designation provides potential incentives for the sponsor from the European Union to develop a medicine for a rare disease, such as protocol assistance, reduced fees, funding from the EC for clinical trials and protection from competition once the medicine is placed on the market, including ten years of market exclusivity.

Zogenix is currently enrolling patients in the U.S. and internationally for a ZX008 Phase 3 program in Dravet syndrome, another intractable, severe epilepsy that begins in infancy. ZX008 is designated as an orphan drug in both the U.S. and Europe, and it also received Fast Track designation in the U.S. for the treatment of Dravet syndrome.
