Zynerba Pharmaceuticals Initiates Open-Label Phase 2 Trial of ZYN002 in Developmental and Epileptic Encephalopathies (DEE)

DEVON, PA, USA I April 10, 2018 I Zynerba Pharmaceuticals, Inc. (NASDAQ:ZYNE), a clinical-stage specialty neuropsychiatric pharmaceutical company dedicated to developing and commercializing innovative pharmaceutically-produced transdermal cannabinoid treatments for rare and near-rare neurological and psychiatric disorders with high unmet medical needs, today announced that it has initiated the Phase 2 BELIEVE 1 (Open Label Study to Assess the Safety and Efficacy of ZYN002 Administered as a Transdermal Gel to Children and Adolescents with Developmental and Epileptic Encephalopathy) clinical trial. The study will assess the safety and efficacy of ZYN002 in DEE, including Lennox-Gastaut and Dravet syndromes. ZYN002 is the first and only pharmaceutically-produced cannabidiol (CBD) formulated as a patent-protected permeation-enhanced transdermal gel.

“DEE is a heterogeneous group of epilepsy syndromes that involve significant developmental impairment or regression of developmental progress, and are highly resistant to treatment,” said Dr. Liza Squires, Zynerba’s Chief Medical Officer. “Little attention is paid to DEE outside of Lennox-Gastaut and Dravet syndromes despite the high unmet need. The BELIEVE 1 study will assess children and adolescents with a variety of epilepsy syndromes that are characterized as DEE. Our goal is to deliver an effective, well tolerated, and easy to administer therapeutic option for individuals living with DEE and their families.”

The six-month BELIEVE 1 clinical trial is an open label multi-dose Phase 2 clinical trial designed to evaluate the efficacy and safety of ZYN002 in children and adolescents (three to <18 years) with DEE as classified by the International League Against Epilepsy (ILAE) (Scheffer et al. 2017). Approximately 50 patients with confirmed DEE will be enrolled in the clinical trial, approximately half of whom may have either Dravet or Lennox-Gastaut syndrome. Enrolled patients will receive weight-based initial doses of 125 mg BID (250 mg daily) or 250 mg BID (500 mg daily) of ZYN002 CBD gel. The primary efficacy assessment is change in seizure frequency. The Company expects to report topline results in 2019.

About Developmental and Epileptic Encephalopathies (DEE)
DEE is a heterogeneous group of epilepsy syndromes that may be associated with severe cognitive impairment and behavioral disturbances. These disorders are often progressive, and are highly resistant to treatment. DEE includes a number of rare and ultra-rare epilepsy syndromes including early myoclonic encephalopathy, epileptic encephalopathy with continuous spike and wave during sleep, and certain syndromes including Ohtahara, West, Landau-Kleffner, Lennox-Gastaut, Doose and Dravet. Improved seizure control may have a positive impact on development and quality of life.
